title: [Effect of cortisol on adenylate cyclase and 3',5'-AMP phosphodiesterase activity and 3',5'-AMP concentration in tissues and biological fluids in experimental atherosclerosis].
abstract: Administration of hydrocortisone into healthy rabbits activated adenilate cyclase and phosphodiesterase in liver tissue; activity of the enzymes was normalized within 5 days after the treatment. The hormone, administered into animals with experimental cholesterol-induced atherosclerosis, caused an activation of adenilate cyclase and inhibition of phosphodiesterase; due to the phenomenon more distinct and long-term increase in cAMP concentration was observed in kidney, liver and fatty tissues. Concentration of cAMP exceeded considerably its initial content in the tissues within 5 days after the hydrocortisone administration. Hydrocortisone inhibited the adenilate cyclase system activity in adrenal cortex of experimental and control animals at early period of the experiment. In health rabbits content of cAMP was increased in adrenal cortex within 5 days after the hormone administration. As the similar effect was not found in animals with experimental atherosclerosis these data suggest that the hypophysis-adrenal cortex system under the experimental conditions studied was inhibited.
