Effects of folic acid deficiency in pregnant Wistar rats on the activities of D5-3 beta hydroxysteroid dehydrogenase and glucose-6 phosphate dehydrogenase in the ovaries of their litters.
Histochemical studies of the activities of glucose-6-phosphate dehydrogenase (G-6-PD) and D5-3 beta-hydroxysteroid dehydrogenase (D5-3 beta-HSD) in the ovaries of 40 day old litters of Wistar rats whose mothers were folic acid deficient from the 13th day of gestation showed very weak or no enzyme activity. Biochemical estimations of these enzymes showed that the specific activity of 3 beta-HSD in the experimental animal was 20% that of control while that of G-6-PD in the experimental animals was 14% that of control. This implies that folic acid deficiency instituted at a critical period in gestation in Wistar rats adversely affects steroidogenesis in the ovaries of their litters.
