Histochemical observations on the adrenal gland of bat Vesperugo pipistrellus (Dobson).

The presence of delta 5-3 beta-hydroxysteroid dehydrogenase (delta 5-3 beta-HSDH), 11beta-hydroxysteroid dehydrogenase 11beta-HSDH), 17beta-hydroxysteroid dehydrogenase (17beta-HSDH) and glucose-6-phosphate dehydrogenase (G-6-PDH) has been histochemically demonstrated in the zona glomerulosa, fasciculata and reticularis and also in the cortical cells that are found interspersed in the medulla of the adrenal gland of the bat, Vesperugo pipistrellus. The present study indicates that the adrenal cortex of the bat is capable of synthesizing corticosteroids and also sex steroids.

Functional morphology of the interrenal and chromaffin cells in the teleosts, Rasbora daniconius (Hamilton), Barbus stigma (Cuv. et Val.) and Channa gachua (Hamilton).

The interrenal cells in Rasbora daniconius, Barbus stigma and Channa gachua are mainly found around the postcardinal vein and its major branches in the haemopoietic head-kidney. The chromaffin cells which are identified by the positive chromaffin reaction are found in the walls of the postcardinal vein or dispersed among the interrenal cells. delta5-3beta-HSDH and G-6-PDH activity was observed in the interrenal cells of all three teleosts. The present work indicates that the interrenal cells are capable of steroid biosynthesis and the chromaffin cells contain biologically active catecholamines.

Steroid dehydrogenases in the kidney of musk shrew, Crocidura caerulea: a histochemical study.

The presence of NADH diaphorase, G-6-PDH, ICDH, delta5-3beta-HSDH, 17beta-HSDH and 11beta-HSDH enzyme activity has been histochemically demonstrated in the renal and the collecting tubules of the kidney of the musk shrew, Crocidura caerulea, a primitive mammal. It is inferred that the kidney is capable of converting delta5-3beta, 17beta- and 11beta-hydroxysteroids to ketosteroids, presumably, during steroid excretion.

Hydroxysteroid dehydrogenases in the kidney of white-breasted water hen, Amaurornis phoenicurus chinensis (Boddaert).

Histochemical localization of delta5-3beta-hydroxysteroid dehydrogenase (delta5-3beta-HSDH), 17beta-hydroxysteroid dehydrogenase (17beta-HSDH), 11beta-hydroxysteroid dehydrogenase (11beta-HSDH) and glucose-6-phosphate dehydrogenase (G-6-PDH) have been studied in the kidney of white-breasted water hen, Amaurornis phoenicurus chinensis. All these enzyme activities occurred in the proximal and distal convoluted and collecting tubules, however, the intensity of these enzyme activities was more in the proximal convoluted tubules. It is suggested that these enzymes might have a role in converting certain hydroxysteroids to ketosteroids during steroid excretion.
