Chemoprotection of ovarian follicles of mice against gamma irradiation by MPG (2-mercaptopropionylglycine).

Chemical protection/Ovarian follicle/Gamma irradiation Adult virgin female Swiss albino mice were irradiated with 2.5, 5 and 10 Gy of gamma radiation in the presence and absence of the drug MPG and changes in the ovarian follicular population were scored at various post irradiation intervals of 3 hours to 14 days. The results indicate that the drug has partially prevented the rapid reduction in the follicular number. Primordial follicles are protected to a greater extent than the growing and large follicles. The difference between the number of follicles of drug treated and non-drug treated animals is greater at low dose group.
