title: Development of the ovarian follicles in relation to changes in plasma parameters and 5 delta 3 beta HSD in snapping turtle, Chelydra serpentina.
abstract: Follicular development in snapping turtle, Chelydra serpentina, was studied in relation to changes in plasma levels of estradiol-17 beta, total protein, calcium, inorganic phosphate and cholesterol. Histochemical reaction for 3 beta-HSD in granulosa and theca cells of the follicles is strong during the preovulatory and vitellogenic phases when the follicles attain their maximum size (18-22 mm) and estradiol is at a high level. The reaction for 3 beta-HSD is weal during the postovulatory phase when the developing follicles are at their minimum size (5-7 mm) and estradiol is low. Administration of estradiol-17 beta causes a rise in plasma calcium, total protein, inorganic phosphate and cholesterol.
