    Abstract:
    Steroidogenic key enzymes, i.e. delta 5-3 beta and 17 beta-hydroxysteroid dehydrogenase (delta 5-3 beta and 17 beta-HSD) activities, in the testis and Bidder's organ of the toad were inhibited and ascorbic acid synthesis in these organs was decreased by a wide range of lithium concentration in in vitro study. A significant inhibition was noted at a concentration of 2.0 mM, which is easily achieved in the blood during the treatment of manic patients by lithium chloride. This experiment reflected that lithium exerts a direct inhibitory effect on hydroxysteroid dehydrogenase activities in the testis and Bidder's organ--a rudimentary ovary in Bufo.
