Determination of dehydroisoandrosterone and 17-ketosteroids.
Methods for the quantitative determination of steroids have been developed, based on their specific chemical or physicochemical properties. The Zimmermann reaction (1) and the Kober reaction (2) have been found useful in the quantitative determination of certain individual steroids occurring in urine. Modifications of these reactions have been reported by Callow et al. (3), Holtorff and Koch (4...

متن کاملThe conversion in vitro of 17-hydroxypregnenolone to cortisol by a human adrenal tumor.
In the generally accepted schemes for the biosynthesis of adrenal cortical steroids (l-3), progesterone* is represented as the branch point in the formation of 17-hydroxycorticosteroids (Reactions D and F, Fig. l), on the one hand, and the 17-deoxycorticosteroids (Reaction E, Fig. l), on the other. Savard et al. (4) found that incubation of slices of an interstitial cell tumor of the testis wit...

متن کاملUrinary excretion of 17-ketosteroids in children.
Determination of the urinary excretion of 1 7-ketosteroids (17-oxosteroids) is the most important laboratory test in the investigation of endocrine disorders involving the adrenal cortex and gonads in children. The normal range of excretion varies with the method employed, since non-steroidal pigment may to a greater or lesser degree be measured as 17-ketosteroid. It is important therefore to k...
