The Effect of Pesticide Residues on the Morphology of Liver of Rats

Abstract

The study of the effect of pesticide residues on the liver of rats was undertaken using thirty Wistar rats, which were randomly separated into three groups, (A,B and C) of ten rats each. The first group (A) was the control group and was fed on normal rat chow. The second group (B) was fed on diet that was stored with pesticide for seven weeks while the third group (C) was fed on diet that was stored with pesticide for fourteen weeks. The feeding experiment lasted for fourteen weeks. The result showed that the liver was affected in rats fed experimental diets. The liver of the test groups, showed various accumulations of degenerative fatty vacuoles and some areas of necrosis, which are more pronounced in group B that group C animals. This shows that the liver was affected due to the pesticide residues present in test diet.
