The use of tetramethylammonium hydroxide (T.M.A.H.) in place of potassium hydroxide in the Zimmermann reaction has been investigated. Although various pure steroids have different colour equivalents, a comparison of the results of 17-ketosteroid and 17-hydroxycorticosteroid estimations on a series of urines showed that the differences for the two reagents were only small and may be ignored. Tet...
The urinary excretion of androsterone, aetiocholanolone, total 17-oxosteroids, and 17-hydroxycorticosteroids (17-OHCS) was measured in 40 patients with lung cancer three days before resection and again 10-15 days after resection of their lung tumours. There was a significant postoperative increase in the excretion of 17-OHCS but a significant decrease in the excretion of androsterone and aetioc...
Possible interference by chlordiazepoxide or its metabolites with some clinical chemical procedures.
We examined the effect on some clinical chemical assays of adding chlordiazepoxide or its two metabolites, the lactam and the N-desmethylchlordiazepoxide, to serum or urine. We also examined the effect on urinary steroid values of administering the drug for as long as 20 days. The drug, in 10-fold the expected concentrations in blood, or its metabohites, in 200-fold the expected Concentration i...
The determination of urinary corticosteroids by their conversion to 17-ketosteroids (17-KS) on treatment of urine with sodium bismuthate has been recently reported (Norymberski, 1952; Norymberski, Stubbs, and West, 1953). The group of corticosteroids thus determined has been termed 17-ketogenic steroids (17-KGS). The interest in this method shown by colleagues from other laboratories prompts us...
