متن کاملA Method for the Rapid Hydrolysis of Urinary Glucuronoside Metabolites of Testosterone.
..A.LMOST ALL the neutral urinary 17-ketosteroids are conjugated with either sulfuric or glucuronic acids. These conjugates can be cleaved by strong acids at elevated temperatures (1), or by solvolysis in either ethyl acetate or tetrahydrohiran, each containing perchioric acid (2). Selective hydrolysis of steroid-glucuronosicles is achieved with $-glucuromi_ idase, although in some 1i1#{149}ill...
متن کاملPlasma testosterone in preterm infants with cryptorchidism.
Cryptorchidism is common in infants born preterm, yet the mechanism for its occurrence is still debated. In a study of 21 premature babies with cryptorchidism at 18 months post-term and 21 case matched controls, cryptorchid preterm infants failed to show the normal rise in plasma testosterone in the first postnatal week. This rise is thought to relate to residual maternal human chorionic gonado...
