CORTISOL UTILIZATION BY SALIVARY GLAND, KIDNEY AND ADRENAL CORTEX

Abstract
SUMMARY Cortisol utilization by salivary glands, kidneys and adrenals of various mammals has been compared by using a standard histochemical technique for the demonstration of hydroxysteroid dehydrogenases. 11β-Hydroxysteroid dehydrogenase activity was localized in salivary gland ducts, renal collecting and convoluted tubules and in the adrenal cortex of some species. There was no obvious relationship between the levels of enzyme activity in the salivary glands, kidneys and adrenals. Neither was the presence of 11β-hydroxysteroid dehydrogenase in salivary glands particularly associated with mucous or serous secretion, nor were sex differences in levels of activity evident.
