F Bhadrakom, 1 and Helmer have employed spirally cut strips of rabbit aorta in a bioassay method for estimation of urinary levels of catechol amines. In attempting to use this method for determination of adrenal venous plasma levels of epinephrine and norepinephrine, the possibility arose that adrenal steroids might alter the contraction of rabbit aortic smooth muscle produced by these eatechol...

It has long been recognized that the usual methods for cleavage of steroidal conjugates by strong acids may effect various transformations (1). In an earlier publication (1) one particular alteration, the conversion of a 3&hydroxy-17-ketosteroid to a non-digitonin-precipitable (“a”)-17-ketosteroid’ by standard HCl hydrolysis was studied. This conversion could be avoided by use of the hydrolytic...

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 c...
