background & objectives:endocrine hormones, through their anabolic or catabolic function, contribute in body homeostasis. they can be used to assess the physical performance in athletes. this study was performed to determine the resistance training (rt) influences on serum cortisol and dehydroepiandrosterone in trained young females. materials & methods:the study population consisted o...

Numerous methods are available for measuring urinary steroids in evaluating endocrine dysfunctions. Measurements of these particular steroids, or groups of them, usually involve tedious isolation methods, corrections for interferences and losses of the steroid, and (or) expensive reagents. We show how gas-liquid chromatography provides a rapid, sensitive, and direct method for several steroid m...

The determination of urinary 17-ketosteroids has limited applications in the understanding and diagnosis of the nature of endocrine disorders associated with mild hirsutism and virilism in the female, because a very large number of these patients excretes 17-ketosteroids well within the normal range. Recent experience of Finkelstein, Forchielli and Dorfman (1) suggests that in these cases the b...

Mammalian steroid sulfatase which cleaves dehydroisoandrosterone sulfate* and certain other steroid sulfates with planar rings A and B, such as sulfates of the 3P-hydroxy-5aandrostane or 5a-pregnane series, was first discovered by Gibian and Bratfisch (1) in ox and rat liver and confirmed by Roy (2). The occurrence and intracellular distribution of the enzyme have been further studied by Roy (3...
