Using the anteroposterior diameter of C3-C7 spinal canals to assess cervical stenosis among Ghanaian males: An anatomical study
type: item
description: Background and aim: Cervical stenosis (CS) occurs when the size of the spinal canal is narrower in an individual than that of the general population. Individuals with CS may be asymptomatic or may present with a wide array of neurological symptoms. There however appears to be paucity of information on the AP canal diameter among Ghanaians. This study therefore, aimed at using the diameter of C3-C7 spinal canals to assess the presence of cervical stenosis in the Ghanaian male population. Material and Methods: The study was carried out using 110 dry cervical vertebrae which the author harvested from 24 male cadavers. The anteroposterior diameter (AP) of the cervical spinal canal for C3-C7 vertebrae were measured using a digital Vernier caliper to 0.01mm precision. Using the means and standard deviations, the spinal canals were classified as relatively narrow or narrow. Results: The percentage of narrow and relatively narrow spinal canals was 1.82% (2) and 10.0% (11) respectively. The C4 vertebra was observed to have the smallest AP diameter 12.38±2.12mm, while C6 had the largest AP dimeter 13.88±1.47mm. AP diameters in the present study were found to differ from Caucasians and African-American males, but were similar to those reported in Asians and Female African-American females. Conclusion: In the present study 11.8% of cervical vertebrae showed some degree of narrowing. The mean AP diameters of the spinal canals in the present study were found to be smaller than those reported in Caucasians and African American males. The findings of the present study suggest the need to develop race and geographic specific criteria for diagnosing CS. Keywords: Cervical Stenosis; Spinal Canal; Cervical Vertebra; Ghana

Investigation of inheritance pattern of palmar creases among the Urhobo and Ogoni Ethnic Groups in South-South Nigeria
type: item
description: Background and aim: Qualitative and quantitative analysis of palmar creases have been implicated for diagnoses of congenital abnormalities as well as prediction of identity, ancestry, and ethnicity. Thus, suggesting the genetic basis of palmar creases. This study investigated the inheritance pattern of palmar creases among the Urhobo and Ogoni ethnic groups in South-South Nigeria. Methodology: In this family-based study 95 families- 60 Urhobo and 35 Ogoni families were recruited. Using dermatoglyphic capture technique, palm prints of the subjects were obtained. Proportion of Concordance was used to determine inheritability. Mendelian Chi-square analysis of trait dominance was used to establish dominant patterns. Results: Inheritance likelihood of pattern of origin of major palmar creases among the Urhobos was 78.3% and 83.3% on the right and left palms respectively while that of Ogoni showed 85.7% on the right palm and 77.1% on the left palm; shape of palmar creases of the Urhobos was 90.0% on the right palm and 93.3% on the left palm while that of the Ogoni was 88.6% and 88.6% on the right and left palms respectively; Middle/Mid longitudinal crease for Urhobo was 88.3% and 93.3% on the right and left palms respectively while that of the Ogoni was 85.7% on the right and left palms respectively. Conclusion: The inheritance of origin/meeting pattern of the major creases is purely under the influence of more than two alleles while that of shape and Middle longitudinal crease tend to suggest a di-allelic influenced expression. Middle longitudinal crease showed purely a dominant-recessive expression.

Zingiber Officinale-supplemented diet reversed lead-induced oxidative stress and cerebral cortex injuries in adult female Wistar rats
type: item
description: Background and aim: Ginger (Zingiber officinale), a widely recognized medicinal plant popularly used as spice has attracted attention due to its ability to boost the immune system and reverse conditions associated with organ toxicity via its anti-oxidative and anti-inflammatory properties. This study assessed the effects of Zingiber Officinale (ginger) on the changes in feed intake, oxidative stress markers (malondialdehyde and total antioxidant capacity) and cerebral cortex injury associated with lead treatment in rats. Materials and methods: Twenty adult female Wistar rats, each weighing between 150 and 170g, were randomly divided into four groups of five animals each (n = 5). Groups A and B; the negative and positive controls were fed with (distilled water) orally via gavage and basic lead carbonate at 30 mg/kg respectively. Both groups A and B were fed with measured standard diet. Groups C and D received a diet supplemented with powdered ginger at compositions of 1% and 5% of their feed respectively. All the administered substances were provided daily throughout the experimental period of 28 days. On day 29, the animals were euthanized by cervical dislocation and blood samples were collected through intra-cardiac puncture, stored in a heparinized bottle, and further processed to assess the levels of oxidative markers (Malondialdehyde and Anti-oxidant status). The brain tissues were extracted, visually examined, weighed, fixed in 10% neutral buffered formalin, processed for paraffin embedding, cut to a thickness of 5μm, and stained with Hemetoxylin and Eosin (H&E) for histological findings. Results: Result showed that ginger reversed decreased feed intake, oxidative impairment, and cerebral cortex injury induced by lead. Conclusion: The consumption of products supplemented with ginger and its usage as spice should be further encouraged. More findings are needed to ascertain its optimal consumption levels in humans.

Cannabinoid exposure during pregnancy: consequences for growth, memory and prefrontal cortex integrity in Wistar Rats
type: item
description: Background and aim: The increasing use of cannabis among pregnant women raises concerns about its potential impact on prenatal development. Many pregnant women use cannabis for its anti-emetic or anti-nausea effects, often under the belief that it is safe during pregnancy. However, prenatal exposure to the primary cannabinoids, THC and CBD, may result in neurodevelopmental deficits in offspring. This study aimed to assess the effects of late prenatal cannabis exposure on neurodevelopment in Wistar rats. Materials and methods: Twenty-four female Wistar rats (12 weeks old) were mated, and pregnancy was confirmed by the presence of spermatozoa in vaginal smears on day 1. The animals were divided into four groups: Control (Group A), Late CBD (Group B), Late THC (Group C), and Late THC/CBD (Group D), with six rats per group. From gestational days 15 to 19, Group A received olive oil, Group B received CBD (150mg/kg body weight), Group C received THC (150mg/kg body weight), and Group D received a combination of CBD and THC (150mg/kg body weight each) via oral administration. After birth, the pups were allowed to grow, and at week 7, the adolescent rats were subjected to neurobehavioral tests. Upon completion of behavioral assessments, the rats were euthanized, and their brains were dissected, fixed in 10% formal saline, and processed for histological analysis. Results: The results showed a significant reduction in birth weight at postnatal day 1 (PND 1) in the CBD, THC, and THC/CBD groups, with an increased percentage of alternate arm return at p< 0.05, morphological changes in pyramidal cells in the prefrontal cortex, indicating impaired cognition. Conclusion: These findings suggest that late prenatal exposure to cannabis, specifically THC and CBD, leads to low birth weight and cognitive impairments in offspring, particularly in the prefrontal cortex.

Chloroform fruit extract of Phoenix dactylifera L. (Date Palm) has neuroprotective effect against lead acetate-induced neurotoxicity in Wistar rats
type: item
description: Background and aim: Environmental and health hazards posed by lead, a heavy metal contaminant, in water and other media are rising. Different solvent-extract forms of the Phoenix dactylifera plant are of vast medicinal benefits. The neuroprotective effect of chloroform fruit pulp extract of P. dactylifera (CFPD) was assessed on lead acetate-induced cerebellar and cerebral toxicity in Wistar rats. Materials and methods: Twenty-four rats were divided into six groups: (A – F; n= 4): the control (group A) was administered distilled water (2 ml/kg p.o); group B received lead acetate (LA, 120 mg/kg body weight p.o) only; group C, received vitamin C (100 mg/kg body weight p.o) as reference drug concomitantly followed by LA (120 mg/kg body weight p.o); groups (D, E, F) received CFPD (125 mg/kg body weight, 250 mg/kg body weight and 500 mg/kg body weight p.o, respectively) concomitantly followed by LA (120 mg/kg body weight). Administrations lasted for 14 days. The neuroprotective effect of CFPD was evaluated using histological (H&E) stained sections of cortical cerebellar and cerebral– (layers III and V) regions as well as biochemical (oxidative stress markers; serum malondialdehyde, superoxide dismutase, catalase, and glutathione peroxidase) assessments. Results: Results revealed neurodegenerative changes in the LA-treated group's cerebellar and cerebral cortices, including perineuronal vacuolation and gliosis. However, the administration of CFPD remarkably ameliorated LA-induced cerebellar and cerebral changes. Relative to the control, the LA-treated group showed altered serum oxidative stress markers, which were ameliorated (p<0.05) with CFPD treatment. Conclusion: Results suggest that CFPD, especially at a dose of 250 mg/kg, has neuroprotective potential against LA-induced cerebellar and cerebral toxicity in rats which could be attributed to antioxidant properties.

The concept of forensic taphonomy: understanding the postmortem processes of dead remains
type: item
description: Taphonomy is the discipline that investigates and interprets all activities that occur to remains after death. Postmortem Interval (PMI) is a critical concept in forensic science and refers to the time elapsed between the death of an individual and the discovery and examination of their remains. Estimating the PMI is often one of the primary objectives in forensic investigations, as it can provide crucial information to investigators, such as the approximate time of death, which is vital in narrowing down potential suspects and reconstructing the events leading to the demise of an individual. By gaining insights into the PMI and the conditions surrounding a body after death, forensic taphonomy can aid law enforcement in solving crime by providing a scientific foundation for estimating when a crime might have occurred. The concept of forensic taphonomy is a dynamic and indispensable aspect of forensic science. It sheds light on the intricate processes that occur after death and helps solve mysteries, bring perpetrators to justice, and offer solace to those affected by the tragedy. As forensic science continues to evolve, so does our understanding of taphonomy, making it an ever-relevant field in the realm of criminal investigations and human identification. The accuracy and dependability of PMI estimates have been substantially improved globally by improvements in methodologies and the incorporation of advanced Systems. However, difficulties still exist, such as differences in insect behavior across geographical regions and the requirement for thorough databases for documented data. Forensic taphonomy is a critical aspect of modern forensic science and as such requires development and research in developing countries hence the purpose of this study.

Study of some anthropometric variables among menopausal women with type II diabetes in Lagos Mainland: Shomolu Local Government Area and its environ
type: item
description: BACKGROUND AND AIM: According to clinical criteria, menopause is when a woman stops having periods for at least 12 consecutive months which involves hormonal changes that can be challenging for diabetic women especially those reliant on insulin. Anthropometric parameters, including body mass index (BMI), waist-to-hip ratio (WHR), are critical indicators of metabolic health and disease risk in menopausal women. Postmenopausal women with type II diabetes often exhibit altered anthropometric parameters such as higher body mass index (BMI), waist circumference, and waist-to-hip ratio (WHR), compared to their non-diabetic counterparts. The aim was to study some anthropometric parameters among menopausal women with type II diabetes in Lagos mainland, Shomolu Local Government Area and its environ. METHODOLOGY: The study was a cross sectional study among the clinically diagnosed type II diabetic menopausal women who attends clinic in Lagos mainland: Shomolu local government and its environs. Seven hundred and two (702) clinically diagnosed type II diabetic menopausal women were recruited from some medical facilities at Lagos mainland. Anthropometric parameters such as height, weight, head, neck, mid upper arm, chest, waist, hip and thigh circumferences were taken using standard procedures. RESULTS: The results indicate the average age at menopause was 46.73±4.44 years and most of the women were diagnosed with Type II Diabetes after menopause (67.2%). CONCLUSION: In conclusion, weak relationship between some Anthropometric parameters, among menopausal women with type II diabetes in Lagos mainland, Lagos state Nigeria.

Modulatory role of cannabidiol and sleep recovery on hepato-renal functions and histological alterations triggered by sleep deprivation in adult male Wistar rats
type: item
description: BACKGROUND AND AIM: Sleep deprivation is a significant health concern, affecting various physiological systems, including hepatic and renal functions. Cannabidiol, a compound found in cannabis plants, has gained attention for its therapeutic potential through its antioxidant and anti-inflammatory activities. This study aimed to investigate the effect of cannabidiol and recovery sleep on hepatorenal functions and histological changes in the kidneys and liver of adult male Wistar rats. MATERIALS AND METHODS: Thirty adult male Wistar rats were divided into five groups (n=6) and were given the following treatments for 21 days: the control group (1ml/kg body weight distilled water), group II [1ml/kg body weight distilled water + 18 hours of sleep deprivation (SD)], group III [10mg/kg body weight of cannabidiol (CBD) + 18 hours SD], group IV [20mg/kg body weight of CBD + 18 hours SD] and group V [1ml/kg body weight distilled water + 18 hours SD + 7 days sleep recovery (SR)]. The modified multiple-platform method was used to induce rapid eye movement sleep deprivation. On completion, the animals were euthanized, and the blood samples were collected via cardiac puncture for biochemical analysis (Aspartate aminotransferase (AST), Alanine aminotransferase (ALT) & Alkaline phosphatase (ALP)], kidney electrolyte, urea and creatinine, serum proteins and oxidative stress biomarker [malondialdehyde (MDA)]. The kidney and liver were harvested, processed, and stained with haematoxylin & eosin for general histoarchitecture. RESULTS: Results from this study showed no notable differences in CBD and SR groups in the liver enzyme concentrations of AST, ALT and ALP], kidney electrolytes and proteins [potassium ions (K+), urea and creatinine] and oxidative stress biomarker (MDA), but there was a remarkable ameliorative effect in the histology of the kidneys and liver of CBD-treated and SR groups compared to the SD-alone group. CONCLUSION: Findings from this study showed that seven days of …

Photogrammetric Evaluation of Some Normative Facial Indices of Young Adults of Igbo Ethnic Group, Nigeria
type: item
description: BACKGROUND AND AIM: Evaluation of facial indices (nasal, canthal, and facial index) has always been of great interest because of its use in forensic science, plastic surgery, orofacial surgery, and population studies. The study aims to evaluate the normative facial indices of young adults of the Igbo ethnic group of Nigeria. METHOD: The study adopted a descriptive cross-sectional study design where 300 respondents participated in the study (150 males and 150 females) between the ages of 18 - 37 years with BMI of 18 – 29 were randomly selected. Subjects whose BMI fell within the category of slightly underweight (≤18.4) and slightly overweight (>24.9) according to conventional BMI classification, looked seemingly healthy and were included in the study. Minimum sample size was determined using the Cochran’s formula. Linear facial parameters and facial indices were calculated using the standard formula, and data obtained were analyzed using IBM SPSS version 23. Continuous variables were presented as mean±SD. Age was grouped into 18-21, 22-25, 26-29, 30-33 and 34-37. Data was presented as mean ± standard deviation. Independent T-test was used to test for significance in the variables between genders, one way ANOVA was used to test for significance in age and variables. A probability less than 0.05 (P<0.05) was considered statistically significant. RESULTS: Facial indices (canthal, nasal and facial index) were 37.67±5.14, 78.85±15.08 and 54.65±5.01 respectively among the males while among the females; 0.23±7.47, 61.26±12.44 and 46.22±14.04 respectively. The study parameters were found to be higher in males (p<0.05). The study analyzed respondents aged 18-21, 22-25, 26-29, 30-33 and 34-37 and found no significant association between canthal, nasal, and facial index and age. The Canthal index was higher in 22-25 years. nasal index values were higher in 34-37 years and facial index in ages 26-29 years. CONCLUSION: Facial indices show significant sex differences and would ser…

A multi-method comparison of body volume and body fat in healthy adults: source of caution for interchangeability of techniques
type: item
description: BACKGROUND AND AIM: The interchangeability of different techniques for volume measurements makes it important to cross-calibrate volumes from different scanning systems against a gold standard Air Displacement Plethysmography (ADP), and identify possible causes of the differences. MATERIALS AND METHODS: A sample of 121 adults (78 males and 43 females, aged 18 – 44 y underwent body volume measurement via ADP (Bodpod system, Cosmed, Rome, Italy) and 3D scanning using portable scanner (Artec L, Artec Luxembourg) and fixed laser scanner (Hamamatsu BLS, Hamamatsu, Japan). Duplicate measurements were undertaken in 12 participants. RESULTS: Measurements were highly correlated between techniques for volume (R=0.989; 0.977 and 0.979; P<0.0001) and inter-technique errors for volumes and girths were <1% technical error of measurement. Bland and Altman analysis revealed volume measurements differed between Hamamatsu and both Artec and Bodpod (P<0.05), but were similar between Artec and Bodpod (P>0.05) and these patterns remained when volumes were converted into %fat. There were no significant differences between anthropometric and 3DS-extracted waist and hip girths for either scanner type (P>0.05). CONCLUSION: Despite their comparability for extracted waist and hip girth, the scanners are not interchangeable for volume and %fat estimation.

Evaluating the anticonvulsant potential of kaurenoic acid isolated from
type: item
description: BACKGROUND AND AIM: Understanding seizure behavior is crucial for accurate diagnosis, effective treatment, and improved patient quality of life. While many antiepileptic drugs (AEDs) can suppress seizures, they often do not address the underlying pathophysiological mechanisms. They may adversely affect memory, mood, and cognition, as seen with phenobarbital (PB). This study aimed to characterize pentylenetetrazole (PTZ)-induced seizures, assess locomotor and exploratory behavior, evaluate hippocampal neuronal impact, and compare the therapeutic effects of kaurenoic acid (KNA) to phenobarbital. METHODOLOGY: Thirty adults male Wistar rats (150–250 g) were assigned to five groups (n = 6): Group 1 (vehicle control, water, 1 ml/kg, body weight), Group 2 (PTZ 40 mg/kg, body weight), Group 3 (PTZ 40 mg/kg, body weight + KNA 400 mg/kg, body weight), Group 4 (PTZ 40 mg/kg, body weight + KNA 800 mg/kg, body weight), and Group 5 (PTZ 40 mg/kg, body weight + PB 10 mg/kg, body weight). Rats' behavior was assessed and were anesthetized with Halothane, the whole brain was extracted and fixed with 10% formalin for histological analysis. RESULTS:The results demonstrated a significant delay in the onset of the first neck muscle jerk (F = 19.29, p < 0.0001) and clonic-tonic seizures (p < 0.0001 and p < 0.01) in KNA- and PB-treated groups compared to PTZ-only controls. Both KNA and PB improved anxiety-related behavior, locomotor activity, and hippocampal cellular condition, although these improvements were not statistically significant (p > 0.05). CONCLUSION: These findings suggest that KNA, like PB, can mitigate PTZ-induced behavioral and cellular disruptions, highlighting its potential as a therapeutic agent for seizure management.

Investigating the effects of aqueous fruit extract of Tamarindus indica on mercuric chloride-induced liver toxicity in adult Wistar rats
type: item
description: BACKGROUND AND AIM: Mercury is a highly toxic metal that poses substantial risks to human health due to its widespread environmental presence and industrial use. Exposure to mercury occurs through various routes, leading to tissue damage mostly liver. The aim of this study was to investigate the effects of aqueous fruit extract of Tamarindus indica on Mercuric chloride-induced liver damage in adult Wistar rats. METHODOLOGY: A total of 42 adult male Wistar rats were divided into six groups with seven rats per group and administered 250mg/kg and 500mg/kg doses of Tamarindus indica extracts and 1mg/kg of mercury chloride. Liver tissues were harvested after administration of the extracts for 60 days and mercury chloride administration for 30 days. The harvested liver tissues were fixed with 10% formal saline for about 24hrs and processed into microscopic slides, and subjected to microscopic examination. Biochemical assays were conducted also to investigate the levels of liver enzymes. RESULTS: Rats in group B treated with mercury chloride showed significant decreases in body weight and increases in liver weight, indicative of the inflammation of the hepatocytes. Elevated levels of liver enzymes and histological changes further indicated liver damage induced by mercury chloride. However, rats treated with Tamarindus indica extracts showed increase on body weight change, liver weight, liver enzymes, and histological alterations, suggesting potential hepatoprotective properties. CONCLUSION: Tamarindus indica demonstrates potential therapeutic benefits in attenuating mercury chloride-induced liver damage, highlighting its role as a natural hepatoprotective agent.

type: item
description: BACKGROUND AND AIM: Significant human exposure to heavy metals such as copper sulfate is a major health concern due to its adverse consequences to body tissue. Vitamin E, a potent anti-oxidant is being investigated for its potential to protect against heavy metal toxicity. This study aimed to investigate the role of vitamin E on copper sulfate-induced liver damage. METHOD: Twenty-five (25) adult Wistar rats weighing between 160g and 220g were divided equally into five groups (A to E). They received 1 ml of distilled water, 200 mg/kg of copper sulfate for 30 days, 200 mg/kg of vitamin E for 30 days, 200 mg/kg of copper sulfate for 30 days followed by 200 mg/kg of vitamin E for 30 days, 200 mg/kg of copper sulfate for 30 days followed by 1 ml of distilled water for 30 days. At the end of the study, blood and liver tissues were collected for analysis of serum Alanine aminotransaminase(ALT), Aspartate aminotransferase(AST), Alkaline Phosphatase(ALP), Total protein(TP), Total bilirubin(TB), Conjugated bilirubin(CB), liver Malondialdehyde(MDA), Superoxide dismutase(SOD), Catalase(CAT), Glutathione Peroxidase(GPx) and histology of the liver. RESULTS: There was significant increase in in ALT, AST, ALP, TB, CB, liver MDA and a significant decrease in TP, liver SOD, CAT, and GPx in copper sulfate treated rats when compared to control which were reversed with vitamin E treatment. Histological findings showed a reversal of vascular stenosis and inflammation induced by copper sulfate following co-treatment with vitamin E. CONCLUSION: Vitamin E possesses ant-oxidant and anti-inflammatory properties against copper-induced liver damage.

Anthropometric evaluation of percentage body fat using skinfold parameters among students of Ebonyi State University
type: item
description: AIM: This study investigates the anthropometric evaluation of percentage body fat using skinfold thickness among students at Ebonyi State University. MATHODOLOGY: A total of 498 participants (243 males and 255 females) aged between 18 to 32 years were recruited for this cross-sectional study. The data were analyzed using the IBM Statistical Package for Social Sciences (SPSS) version 26.0, with descriptive statistics expressed as mean ± standard deviation and correlation coefficients determined for various age groups at two-tailed significance levels of <0.001 and <0.05. The percentage body fat was calculated using the Jackson and Pollock equations and the Siri method. RESULTS: The results reveal significant differences in skinfold thickness and body composition between genders across various age groups. Males exhibited higher mean values in height (169.57 cm to 172.03 cm) and weight (59.06 kg to 62.59 kg) compared to females (165.19 cm to 167.16 cm and 55.15 kg to 56.97 kg). Notably, females showed higher skinfold measurements at most sites, with significant variations observed particularly in the triceps and anterior thigh skinfolds. The correlation analyses indicated that the relationships between various anthropometric parameters were generally weak, with all p-values exceeding 0.05, thus suggesting no significant correlation. The analysis of percentage body fat across different age groups highlighted a trend of decreasing body fat for both males and females after the age of 24, with males averaging between 21.29% to 24.31% and females ranging from 22.41% to 24.73%. CONCLUSION: These findings underscore the need for targeted health interventions in university populations to promote healthy body composition, particularly among younger adults, and suggest that lifestyle factors may contribute significantly to the observed differences in body fat distribution between genders as they age.

description: BACKGROUND AND AIM: Cadmium (Cd), a natural element of the earth’s crust, induce reproductive dysfunction through oxidative stress. Newbouldia laevis is a free radical scavenger. Our study investigated the effect of aqueous leaf extract of Newbouldia laevis (NBL) on cadmium chloride-induced toxicity in pituitary-testicular axis of adult male Wistar rats. METHODOLOGY: 25 male Wistar rats weighing 130-180g were divided into 5 groups of 5 rats each; control (distilled water), 3mg/kg body weight of CdCl2, 3mg/kg body weight of CdCl2 + 300mg/kg body weight of NBL, 3mg/kg body weight of CdCl2 + 450mg/kg body weight of NBL, 3mg/kg body weight of CdCl2 + 600mg/kg body weight of NBL Newbouldia laevis was administered orally and a single dose of 3mg/kg body weight of CdCl2 subcutaneously both for 4 weeks. Semen analysis was evaluated, also the serum was used for the oxidative stress markers, sex hormones and histoarchitecture of the testes were evaluated. RESULTS: There was a dose-dependent effect of NBL on the semen analysis and sex hormones when compared to the CdCl2 group. NBL significantly (P˂0.05) increased SOD, CAT, GSH activities, and decreased Malondialdehyde when compared to the CdCl2 group; and it was dose-dependent effect. Histologically; at the dose of 300mg/kg body weight, there was degeneration in the seminiferous tubules, widening of interstitial spaces and testicular necrosis; while at 450mg/kg body weight, there was a reduced portion of seminiferous epithelial diameter, no germ cells at any spermatogenic phases, cluster of Leydig cells seen in the interstitial space, degenerative changes of seminiferous tubule and reduction in the diameter of the seminiferous tubule. However, at the dose of 600 mg/kg body weight; the testes revealed seminiferous tubules with increased diameters, present of Sertoli cells around the basement membrane, spermatozoa are seen in the lumen of seminiferous tubule while cluster of Leydig cells are present in the interstitial space.

Histopathological Assessment of Cardiac Tissue in Arsenic Trioxide-Induced Wistar rats: Effects of Ethanol Leaf Extract of Irvingia gabonensis
type: item
description: BACKGROUND AND AIM: The toxic effects of drugs and other related substances have attracted concerns from scientists. The passion about the availability of effective and cheap substances against organotoxicity in humans is increasing daily. This work assessed the histopathological changes in the heart of arsenic trioxide-induced Wistar rats and the effects of ethanol leaf extract of Irvingia gabonensis. METHODOLOGY: Forty-two adult Wistar rats weighing between 160-190g were randomly divided into six groups of seven rats each. Group A served as the control, Group B received 10 mg/kg body weight of arsenic trioxide only, Groups C and D received 250 and 500 m/kg body weights of ethanol leaf extract of Irvingia gabonensis only respectively, Groups E and F received 250 and 500 mg/kg body weights of ethanol leaf extract of Irvingia gabonensis in addition to 10 mg/kg body weight of arsenic trioxide respectively. All administrations were through oral route for 28 days. After sacrifice, cardiac tissues were harvested, fixed in 10% neutral buffered formalin and processed for haematoxylin and eosin staining. RESULTS AND CONCLUSION: Histological findings show that arsenic trioxide caused vascular distortion, perivascular infiltrates of inflammatory cells and focal myocardial degeneration. Treatment with graded doses of ethanol leaf extract of Irvingia gabonensis achieved a remarkable amelioration, with 250 mg/kg body weight having a better ameliorative effect, thus suggesting that ethanol leaf extract of Irvingia gabonensis exhibits cardioprotective activity against arsenic trioxide-induced damage and could be a potential cardioprotective substance.

Comparative study on the contraceptive effects of butanol and dichloromethane fractions of Carica Papaya male tree bark in male Sprague Dawley rats
type: item
description: BACKGROUND: The use of Carica papaya extract in traditional medicine suggests that it might have contraceptive effects on reproductive indices. Traditional healers in Nigeria have used male tree bark of Carica Papaya as a source of antifertility agent. . However, there are few information in scientific literature concerning the male tree bark extract of Carica papaya and media of preparation. AIM: The aim of this study was to compare the contraceptive effects of butanol and dichloromethane fractions of male Carica papaya tree bark. METHODOLOGY: The male tree bark of Carica papaya was dried and blended into powdery form, then dissolved in water. The solution was fractionated by column chromatography with petroleum ether and further fractionated using butanol and dichloromethane to isolate butanol (CPFB) and dichloromethane (CPFD) fractions respectively. A total of fifteen animals were divided into three experimental study groups A, B and C. Groups A and B received moderate doses of 75 mg/kg body weight of CPFB and CPFD for 28 days respectively while group C received distilled water. Animals were euthanized after 4weeks of administration, the testes were removed, and used for sperm count and motility evaluations. Blood sample were collected via left ventricular cardiac puncture and used to assay testosterone, luteinizing hormone and follicle stimulating hormone levels. RESULTS: The fractions from both media have contraceptive effect, however the semen analysis of CPFB group showed significantly decrease (p<0.01) in reproductive hormones and corresponding decrease in sperm count and motility when compared with the CPFD group. Hence the CPFB group showed more contraceptive potential than the CPFD group when compared with the normal state of the control group. CONCLUSION: The findings from this present study showed that the butanol fractionation of male sex Carica papaya tree bark demonstrated more contraceptive effects than the dichloro methane fractionate, making Butan…

Assessment of the Ameliorative Effect of Vitamin A on Heat Stress Using White Albino Mice
type: item
description: BACKGROUND AND AIM: Biofortification of food and food addictives with vitamin A is basically aimed at improving vision and or preventing the occurrences of vision related diseases. This usually entails the inclusion of a defined amont of the said micronutrient in a target food. Thus, fortification of animal feed with vitamin A to ameliorate heat stress and increase animal production is possible if the ideal concentration of the said micromutrient is determined for inclusion. Therefore, Aim: this study aims at assessing the ameliorative role of vitamin A (retinol) in the management of Heat Stress (HS). MATERIALS AND METHOD: Thirty adult male albino mice were divided into six (6) groups of five (5) rats per groups. Methodology: Group I was the normal control and was not exposed to heat stress.While groups III and IV were exposed to 57 mw/cm2 of solar radiation at 37oC, groups V and VI were exposed to 98 mw/cm2 of solar radiation at 47oC. Exposure to solar radiation lasted for 21 days during which groups II, III-VI were administered 30 mg/kg body weight of vitamin A for 21 days as well. RESULTS: Feed intake for groups III-VI was significantly (p<0.05) lower than that of groups I and II. Finial body weights for groups III-VI were significantly (p<0.05) lower than the initial body weight. Thiobarbituric Acid Reactive Substance (TBARS) for groups III-VI was significantly (p<0.05) higher than that of groups I-II. CONCLUSION: It can be deduced from this study that 30 mg/kg of vitamin A did not ameliorate varying magnitudes of heat stress studied.

Morphological Assessments and Sexual Dimorphism of the Visual Pathway Structures of Cricetomys gambianus (African Giant Rats Waterhouse-1840)
type: item
description: BACKGROUND AND AIM: Cricetomys gambianus (African Giant Rat (AGR) a nocturnal rodent has recently been a choice model for several areas of neuroscience research. This study assessed sexual differences in the morphometric parameters of visual pathway structures of the AGR. MATERIALS AND METHODS: Ten healthy adult AGRs (n=5; Male (M) and Female (F)) were captured from the wild and used for this study. The ARGs were sedated and body weight obtained before perfusion and decapitation. The weight and dimensions of the brain, eyeballs, optic nerve, optic chiasma and optic tract were obtained using digital weighing balance and Vernier caliper, respectively. Data obtained were analyzed using Statistical Package for the Social Sciences (SPPS) version 23. Results were expressed as mean ± SEM. RESULTS: Average body weight of AGRs was 787±208.6 g for males and 926±133.0 g for females; Brain weight was 6.7±0.6 g for males and 6.9±0.6 g females; while eyeball weight was 0.23±0.02 g for males and 0.22±0.02 g for females. Significant (p<0.05) sexual differences were observed in the dimensions of eyeball antero-posterior diameter (M=7.19±0.24 mm; F= 6.56±0.17 mm); Eyeball right-left diameter (M=6.12±0.11 mm; F= 5.27±0.19 mm); Optic nerve length (M=2.18±0.18 mm; F=1.42±0.13 mm); Optic tract length (M=1.21±0.16 mm; F=1.02±0.08 mm); Optic chiasma antero-posterior length (M=1.02±0.24 mm; F=0.66±0.05 mm) and Optic chiasma right-left length (M=0.80±0.07 mm; F=0.73±0.05 mm). CONCLUSION: There exists sexual dimorphism in the morphometric parameters of visual pathway structures in the AGR. These differences are suggestive of evolutionary advantage in males compared to females as they go out in search for food and easy escape from predators within their natural habitat.

Assessment of epidemiological risk factors of humeral fractures using x-ray findings of patients presenting at Irrua Specialist Teaching Hospital, Irrua, Edo State, Nigeria: A 2-year review
type: item
description: BACKGROUND AND AIM: Humeral fractures are among the most common fractures occurring today. In Nigeria, humeral fractures have been reported to account for nearly 3% of all fractures in adults and for about 20% of all fractures in some populations. This is expected to triple in the next three decades. This study aimed to assess the pattern of humeral fractures in Irrua Specialist Teaching Hospital (ISTH), Irrua, between January 1, 2020, and December 31, 2021, to provide baseline epidemiological data that can help practitioners prepare for effective treatment and management of humeral fractures. MATERIALS AND METHOD: The study was a retrospective descriptive study of records of humeral fracture patients who had x-rays done to determine the pattern of humeral fractures while being managed at ISTH, Irrua over the 2 years. All 35 cases that met the inclusion criteria were selected for the study. The resulting data was analyzed using Microsoft Excel and presented in distribution tables. RESULTS AND CONCLUSION: The result of this study shows that the incidence of humeral fracture was higher in males, while the adult age group (18 to 59 years) was the most affected by humeral fractures (n = 23, 65.70%). Road Transport Accidents were the leading cause of humeral fractures (n = 25, 71.40%) while the midshaft fractures of the humerus were more prevalent. There is a need for those in charge of healthcare planning at ISTH, Irrua to ensure that equipment and manpower needed for the treatment of humeral fractures are readily available and traffic authorities could devise means of reducing the incidence of Road Transport Accidents.

Effects of Vernonia ambigua on testicular histology, selected semen profiles and serum oxidative stress biomarkers of Wistar rats
type: item
description: BACKGROUND AND AIM: Infertility has become an ever-present growing reproductive concern worldwide, with male factors evading required scrutiny due to entrenched cultural beliefs, in lieu of scientific proofs. Though researchers’ contribution is palpable, there is still persistent need for more study in this area. This study aimed to evaluate the effects of Vernonia ambigua on testicular histology, selected semen profiles and serum oxidative stress biomarkers of Wistar rats METHODOLOGY: Twenty rats weighing 200-220g were grouped into four. Each group had five rats. Group A received feed and water. Groups B, C and D received 100mg/kg body weight, 200 mg/kg body weight and 400 mg/kg body weight of Vernonia ambigua respectively for 2 weeks. On the 15th day, blood (serum) samples were collected for oxidative stress biomarkers estimation. Histology of the testis and semen parameters were examined. One way Analysis of Variance in Statistical Package for Social Science was used for data analysis with significance difference set at P < 0.05. RESULTS: Mild testicular distortion was observed in group D. The levels of glutathione, catalase, superoxide dismutase and malondialdehyde in groups B, C and D showed no significant difference when compared to levels of the variables in group A. The same outcome was observed in the comparison of sperm viability, morphology and count of groups B, C and D to group A. CONCLUSION: Vernonia ambigua at lower dose, shows promising antioxidant and reproductive effects especially when sperm viability is preferred to sperm count.

Relationship between somatotype categories and musculoskeletal discomforts among Nigeria school students: A case study of selected secondary schools in Lagos State
type: item
description: BACKGROUND AND AIM: Dimethyl There are rare study on the impact of somatotype on musculoskeletal discomfort in young and adolescence students. This aim of this study was to investigate the association between musculoskeletal discomforts and somatotype (body form) of students in secondary schools. METHOD: A cross-sectional study of total sample size of 640 students from age 10 to17 was taken across privately operated schools and government operated schools, and were categorized into age group of 10-11, 12-13, 14-15 and 16-17. Anthropometry data of the students was collected using International Society for Anthropometric Analysis of Kinanthropometry (ISAK) model and Musculoskeletal discomfort (pain) level was taking using Numeric Rating Scale for Pain (NRPS) which ranges from No Pain to Severe Pain. The student’s somatotype category was determined using the Heath Carter method and the frequency for the pain analysed. A Descriptive Statistics and Chi-Square (χ2) Test Analysis was done between the two categorical variables to ascertain association and its significance. Statistical significance set at p< α=0.05. RESULTS: The results show variation in frequency of pain outcome for students across age groups and schools, however, in totality the frequency of students that reported no pain is low compared to other categories of pain. There is noticeable difference in the frequency somatotype categories of students in private school and public schools across age groups. The ectomorph in private school is high (117) as compared to public school (97), the mesomorph is 95 and 111 for private school and public school respectively while endomorph is 106 and 114 for both school category. The Pearson Chi-Squared test Analysis shows an association between somatotype categories and pain outcome, and there is statistical significance. CONCLUSION: Based on the results of the analysis, we therefore conclude that, Somatotype of any category does have association with any form musculoskel…

The anthropometric indices of physical development in medical students at the University of Lagos, Nigeria
type: item
description: BACKGROUND AND AIM: Limited data is available about the anthropometric indices of physical development of medical students of the University of Lagos Nigeria. This study aims to generate anthropometric data on selected body circumference variables of physical development among medical students in Urban Lagos. MATERIALS AND METHOD: Simple Random Sampling was deployed to select 157 undergraduate volunteers aged 16-26 years from Medical and Dental students of the College of Medicine the University of Lagos. Anthropometric measurements of weight (kg), height (cm), chest circumference (cm), mid-upper arm and arm flexed circumference (cm), waist circumference (cm) and hip circumference (cm) were taken in accordance with the recommendation of International Society for the Advancement of Kinanthropometry (ISAK). Body composition indices such as body mass index (BMI) and height-weight ratio (HWR) were calculated. The data obtained was collated and analysed for Descriptive Statistics (Mean and Standard Deviation). RESULTS: Results show that female medical students were taller and has accumulated more weight than their male counterpart. Both males and females had a slightly closer BMI. There is a slightly higher HWR for males than females. The Mid-Upper Arm circumference was higher in males than in females. The waist circumference revealed a higher girth in male medical students than female medical students. CONCLUSION: This is consistent with the fact that the females have an earlier adolescent rapid growth spurt than males. This study has generated a database on some specific anthropometric indices of growth and physical development in male and female medical students in urban Lagos, and the results indicated that there were differences in the pattern of variation depending on the specific dimensions and indices being evaluated.

Ameliorative effect of Vernonia amygdalina on lead-induced neurotoxicity on the premotor cortex of adult Wistar rats
type: item
description: BACKGROUND AND AIM: Lead toxicity affects different body systems including the nervous system, resulting in brain damage, neuromuscular weakness, and impaired cognitive functions. This study evaluated the ameliorative effect of aqueous leaf extract of Vernonia amygdalina (AEVA) on lead acetate-induced neurotoxicity of the premotor cortex of adult Wistar rats. METHODOLOGY: Thirty adult male Wistar rats were divided into six groups of five each. The rats were accessed for neurobehavioral studies using a foregrip strength test apparatus. Group I received 1ml/kg body weight of distilled water. Group II received only 120 mg/kg body weight of lead acetate. Group III received 120 mg/kg body weight of lead acetate for 1 week and 2 weeks of natural recovery. Group IV received 120mg/kg body weight of lead acetate and 10mg/kg body weight of Succimer. Group V and VI received 120mg/kg body weighr of lead acetate with 1000mg/kg, and 1500mg/kg body weight of AEVA respectively. Administration lasted for 21 days. At the end of the experimentation, the rats were euthanized and brains harvested for oxidative stress, and histological (H&E) assessments. RESULTS: A decrease in muscular strength of Wistar rats treated with lead acetate was observed, however, improvement was seen in all the treatment groups, although, it was statistically significant Oxidative stress was induced in rats exposed to lead acetate as indicated by decreased superoxide dismutase, and catalase respectively. However, 1500mg/kg AEVA treatment ameliorated these changes with a significant increase. The results revealed histopathological changes such as karyorrhexis, cytoplasmic vacuolations, pyknosis and karyolysis in the premotor cortices of lead acetate-exposed rats which were ameliorated when treated with AEVA at 1000 and 1500 mg/kg body weight. CONCLUSION: This study therefore concludes that aqueous leaf extract of Vernonia amygdalina ameliorated lead-induced neurotoxicity of the premotor cortex of adult Wistar r…

Reproductive impact of Mishenland Polyherbal Mixture on steroid hormone-induced gonadotoxic effects in male Wistar rats
type: item
description: BACKGROUND AND AIM: Testosterone and its analogs have been used for anabolic and androgenic purposes for several decades. Initially restricted to professional bodybuilders, these substances have become increasingly popular among recreational athletes. The Mishenland polyherbal mixture (MPM) is a herbal preparation used locally for managing benign prostatic hyperplasia (BPH) and is claimed to reverse infertility of unknown cause in men. The aim of study was to investigate ability of MPM to mitigate the gonadotoxic effects of prolonged steroid hormone exposures in the adult male Wistar rats. MATERIALS AND METHODS: This study used 25 adult male albino rats of age 9 weeks. The animals were divided into five groups of five rats each. After a two-week acclimatization period, all animals except the normal control group received combination doses of 4 mg/kg body weight (bw) testosterone (T) and 0.8 mg/kg bw estradiol (E2) subcutaneously on alternate days for 6 weeks. From the seventh week, experimental groups received 1 ml/kg, 2 ml/kg, and 4 ml/kg bw of MPM, while the control group received 2 ml/kg bw of distilled water. After 4 weeks of treatment, all animals were sacrificed, and their reproductive organs were removed for histological processing (H&E stain). RESULTS: The testes showed evidence of spermatogenic arrest with partial recovery of the spermatogonia stem cells following MPM treatment. The medium dose-2ml/kg herbal treatment group exhibited greater recovery compared to the control. Priapism persisted in hormone-induced hypogonadal control animals. The induced hypogonadic group (IHPG) had the highest mean packed cell volume (PCV), followed by the normal dose MPM group. CONCLUSION: MPM demonstrated a mild ability to restore impaired reproductive function in hormone induced gonadotoxic animals and prevented priapism development observed in untreated hormone-exposed animals.

Evaluation of common ultrasound findings in female patients who present with pelvic pain at Irrua Specialist Teaching Hospital (ISTH), Edo State, Nigeria
type: item
description: BACKGROUND AND AIM: Pelvic pain is the abdominal pain located below the level of the umbilicus including lower back pain with or without radiation into the thighs. It may be acute, intermittent or chronic. This usually affects women more than men possibly because of genetic, hormonal, sociocultural, reproductive organ differences, and anthropological reasons. In women, pelvic pain can be an indication that there may be a problem with one or more of the organs within the pelvic region such as the urogenital and reproductive organs. This study aimed to evaluate the common causes of pelvic pain in females using the ultrasound findings of patients presenting at Irrua Specialist Teaching Hospital, Irrua. MATERIALS AND METHOD: This study adopted a retrospective non-experimental design to obtain and analyze data from the Radiology Department, Irrua Specialist Teaching Hospital, Irrua over eighteen months. 1599 cases were obtained using a convenience sampling method. The resulting data was analyzed using SPSS software version 28.01.1. RESULTS AND CONCLUSION: Findings from this study showed that females aged 15-49 accounted for 52.60% of the cases whose ages were specified. The transabdominal scan was the dominant ultrasonographic technique used for pelvic evaluation. Uterine fibroid, pelvic inflammatory disease and ovarian cyst were responsible for the majority of the pelvic pain in the cases where pathology was identified, while ovarian adenocarcinoma, hepatitis, and leiomyosarcoma were least implicated in pelvic pain aetiology.

Protective effects of Moringa oleifera oil on permethrin-induced toxicity in the prefrontal cortex of young male Wistar rats
type: item
description: BACKGROUND AND AIM: Permethrin is a type I pyrethroid commonly used as an insecticide in pest control. Although it is intended for use in agricultural and textile settings, including residential areas, its extensive use poses a probable risk of human exposure. This study was conducted to determine the changes in the prefrontal cortex following permethrin exposure and the possible protective effects of Moringa oleifera oil. METHODOLOGY: Sixteen young male Wistar rats were randomly selected and divided into four (4) groups (n=4). Group A (Control group) received a normal rat diet, while Group B received a permethrin diet (0.6% Permethrin) at the dose of 1000 mg/kg. Group C received a normal diet and was administered 0.5 ml/kg of Moringa oleifera oil, while Group D received both the permethrin diet and Moringa oleifera oil simultaneously. Animals underwent behavioural analysis on the final day of treatment. The rats were then anesthetized and sacrificed, followed by transcardial perfusion with normal saline and 4% paraformaldehyde. The prefrontal cortex was excised from the brain and processed for tissue histochemistry and biochemical analysis. RESULTS: Results revealed reduced locomotory and exploratory activities and increase anxiety level in rats, as well as cytoarchitectural distortion, cell vacuolation, and redox imbalance in the prefrontal cortex. Administration of Moringa oleifera oil led to significant improvement in neurobehavioral deficits, a comparatively normal cytoarchitectural profile, and oxidative status caused by permethrin in prefrontal cortex of male rats. CONCLUSION: Findings in this study indicated that Moringa oleifera could ameliorate the damage caused by permethrin in prefrontal cortex of male Wistar rats.

Morphometric Study of Lower Lumbar spinal canal and canal/body ratio Using Computed Tomographic Images among apparently normal adult Nigerians
type: item
description: INTRODUCTION AND AIM: Lumbar spinal canal play an important role in causes of low back pain, with lumbar spinal canal stenosis being the major causative factor for back pain. Accurate morphometry of the Lumbar vertebrae may be needed for various purposes including spinal fixation in case of fracture. The aim of this study was to determine the morphometry of the lumbar spinal canal as well as the canal/body ratio. MATERIALS AND METHODS: Four hundred (200 males and 200 females) adults Nigerians with age ranged from 18-65 years. Sagittal diameter of spinal canal (SDC) and Sagittal diameter of vertebral body (SDB) were measured from the third to fifth lumbar vertebrae (L3 to L5) and their ratio calculated. The sexes of 3rd, 4th and 5th lumbar vertebrae were determined by demarking points using the formula: Mean ± 3×Standard Deviations. A probability value <0.05 were considered as statistically significant. RESULTS: The results showed mean SDC and SDB increased gradually from L3 to L5 with minimum at L3 and maximum at L5. On comparing SDC and SDB between male and female subjects, it was observed that both SDC and SDB were greater at all levels in male subjects compared to female subjects and were all statistically significant (p<0.001). Canal/body ratio ranged between 0.56 to 0.59 in male subjects and 0.59 to 0.62 in female subjects from L3 to L5 respectively. CONCLUSION: Transverse diameter was the largest dimension of spinal canal and proportional to the size of vertebral body at each level.
