The physiological disposition and metabolic fate of cortisone in man.

چکیده
In an earlier paper we described studies on the physiological disposition and metabolic fate of hydrocortisone in man (1). This paper describes similar studies on cortisone. Although contributing very little to the body pool of adrenal cortical steroids, cortisone has been used extensively as a therapeutic agent, and it was therefore of interest to compare its metabolism with that of hydrocortisone. Large doses of cortisone and hydrocortisone were administered intravenously and rates of disappearance from the plasma determined in normal subjects and in patients with liver disease, myxedema, thyrotoxicosis, and rheumatoid arthritis. Trace quantities of cortisone-4-C" and hydrocortisone-4-C" were employed in certain studies. From these studies, information was obtained regarding rate of metabolic transformation, rate of absorption, rates and routes of excretion of cortisone and its metabolites, and, to some extent, the identity and amount of these metabolites. Information was also obtained on the in vivo conversion of cortisone to hydrocortisone.

The metabolism of corticosterone in man.
Corticosterone was the first biologically active hormone to be isolated from adrenal gland extracts (1, 2). Although contributing little to the body pool of adrenocortical steroids in man, it is one of the major adrenocortical secretory products in some animals, e.g., rodents (3). In man the major glucocorticosteroid is cortisol and the major mineralocorticosteroid is probably aldosterone; neve...

The dopamine agonist rotigotine was developed for the treatment of Parkinson's disease and restless legs syndrome. Disposition, metabolism, elimination, and absolute bioavailability of rotigotine were determined in six healthy male subjects by using two different forms of administration in a randomized sequence with a crossover design.

,Melatonin (N-acetyl-5-methoxytryptamine), the most potent melanocyte-contracting substance known, has been demonstrated in bovine pineal glands and peripheral nerve of man, monkey, and cattle (1,2). Its formation from seratonin, by.N-acotylation (3) and subsequent 0-methylation (4), has been indicated. In a preliminary communication, we provided evidence for 6-hydroxylation as the major metabo...
