✦ Synopsis

Since interrenal activity of A5-3P-hydroxysteroid dehydrogenase (A5-3P-HSD) in tadpoles during development follows the pattern of metamorphic progress (Hsu et al., '80) and A5-3P-HSD is a key enzyme in biosynthesis of corticosteroids, hypophysectomized (HX) tadpoles of Rana catesbeiana were injected with thyroxine (T4) or ACTH or T4 + ACTH. The un-

## Abstract Little information is available for neurosteroidogenesis in the central nervous system (CNS) of lower vertebrates. Therefore, in the present study, we examined the enzymatic activity and localization of 3β‐hydroxysteroid dehydrogenase/Δ^5^‐Δ^4^‐isomerase (3βHSD), a key steroidogenic enz
