Enzymatic Hydrolysis of Urinary Sodium Pregnasediol Glucuronidate to Free Pregnanediol*
The available evidence suggests that most of the steriod hormone endproducts which are eliminated from the body by way of the urine are conjugated with an inorganic or organic acid. This conjugation presumably facilitates their transportation and excretion by rendering them soluble in water or urine. Examples of such conjugated steroids which have been isolated from urine as sulfates are andros...
متن کاملExcretion of Sodium Pregnanediol Glucuronidate
Venning and Browne (1 to 7) have shown that sodium pregnanediol glucuronidate is excreted in urine of human pregnancy in concentrations which become increasingly higher as gestation approaches term. Although this demonstration has been repeatedly confirmed (8 to 16), relatively few workers have studied the precise levels and ranges of normal excretion, or have secured long-continued records of ...
متن کاملInfluence of Nitrogen Bases on Epoxidation of Cyclooctene with Sodium Periodate Catalysed by Manganese(III) Porphyrins
Effects of imidazoles and substituted pyridines and pure s-donors on the oxidation of cyclooctene with NaIO4 by 5,10,15,20-tetraphenylporphyrinato-manganese(III) acetate, Mn(TPP)OAc, and 5,10,15,20-Tetramesitylporphyrinato-manganese(III) acetate, Mn(TMP)OAc, catalysts in CH2Cl2-H2O solvent are studied. Coordination of the nitrogen donors to the Mn...
متن کاملMonitoring the Reproductive Status of Dairy Cows by Urinary Pregnanediol Glucuronide
This study was undertaken with the aim to establish a reliable radioimmunoassay (RIA) system for urinary pregnanediol glucuronide (PdG) and to employ it for monitoring the reproductive status of dairy cows. Urine and blood samples were collected from the Holstein cows both pregnant and non-pregnant. The samples were then investigated for evaluating the relationship between progesterone (P4) in ...
متن کاملIdentification of anovulation and transient luteal function using a urinary pregnanediol-3-glucuronide ratio algorithm.
The sensitivity and specificity of a urinary pregnanediol-3-glucuronide (PdG) ratio algorithm to identify anovulatory cycles was studied prospectively in two independent populations of women. Urinary hormone data from the first group was used to develop the algorithm, and data from the second group was used for its validation. PdG ratios were calculated by a cycles method in which daily PdG con...
