Effect of Lead Acetate on Follicular Count of Mice Ovary and the Protective Role of Garlic Extract

Objective: The study was conducted to evaluate the effects of lead acetate and protective role of garlic extract on the histomorphology of the ovarian follicles in an animal model. Study Design: Laboratory based randomized control trial Place and Duration of Study: Department of Anatomy, Army Medical College in collaboration with National Institute of Health from April—June 2013 Material and Methods: Thirty female BALBc mice were selected. Mice were randomly divided into three groups. 10 animals were placed in each group. Group A being the control was given normal diet. Group B was given lead acetate at a dose of 30 mg/kg/day. Group C was given lead acetate 30mg/kg/day and garlic extract 500 mg/kg/day through oral lavage tube for 60 days. Animals were sacrificed and dissected at the end of 60th day. Length and width of the ovary were measured, right ovary was processed, embedded and stained for histological study. Primary, secondary and graafian follicles were counted and noted. Results: There was reduction in the number of primary and graafian follicles in group B when compared to group A. In group C there was relatively increase in number of follicles, when compared to group B. Number of secondary follicles was almost same in all the groups. The length of ovary was higher in group A as compared to group B. In group C results were same as group A regarding length of the ovary. Width of ovary was same between the respective groups. Conclusion: The follicular count was markedly affected in lead acetate treated group which improved when co treated with garlic extract in experimental group C. Hence, garlic had a protective role against lead induced changes in mice ovary.
