THE COLORIMETRIC ASSAY OF TOTAL, a-, AND p-17- KETOSTEROIDS IN EXTRACTS OF HUMAN URINE*
The present paper reports a method for determining the respective concentrations of total, o(-, and /3-17-ketosteroids in urine which is based upon the previously reported method of assaying mixtures of crystalline androsterone (a-steroid) and dehydroisoandrosterone (p-steroid) (1) and a simple means of eliminating the interfering effect of the non-ketonic substances from the calorimetric deter...
متن کاملThe conjugated steroids. IV. The hydrolysis of ketosteroid sulfates.
Specific hydrolysis of the separate groups of steroid conjugates appeared to offer the simplest technique for achieving the hydrolysis without chemical modification of the steroids (3-5). A partial solution to this problem was offered when it was found that steroid glucuronides could be hydrolyzed specifically by the use of /3-glucuronidase concentrates of either animal (Cohen (3)) or bacterial...
متن کاملUrinary Excretion of Individual 17-ketosteroids by Normal Children.
Our knowledge of the functions of the normal and diseased adrenal cortex in adults is still slight and we know even less about it in newborn babies and in children. In the past few years an increasing number of methods for examining adrenal function have been described. In addition to the determination of the total amount of 17-ketosteroids (17-KS) and of 17-hydroxycorticoids (17-OH) excreted i...
متن کاملTotal neutral 17-ketosteroids; clinical method for measurement.
ITH INCREASING DEMAND for the determination of urinary total 17-ketosteroids as a diagnostic tool, a need has developed for a , rapid method suitable for clinical use. Such a method was pubby Drekter et al. (1) and modified by Masuda and Thuline (2). We further modified the latter method to permit a larger number of s to be run at one time. We have substituted equipment which is akable and less...
متن کاملUrinary 17-ketosteroids in various endocrine disorders.
HE PURPOSE OF THE PRESENT REVIEW of the literature is an examination of the contemporary data on the clinical diagnostic value of the determination of the 17-ketosteroid content in the urine in various disorders of the endocrine glands. The basis of the chemical structure of the 17-ketosteroids is the perhydrocyclopentanophenanthrene ring. The 17-ketosteroids can be looked upon as derivatives o...
