Metabolites of Naloxone in Human Urine
Journal of Pharmaceutical Sciences, 1971Naloxone, 7,8-dihydro-14-hydroxynormorphinone, and N-allyl-7,8-dihydro-14-hydroxynormorphine have been idenfied in a human urine specimen after naloxone administration. The metabolites were isolated, after hydrolysis with glusulase, by column chromatography and identified by TLC and spectrofluorimetry.

Nature, 1970
So far, only circumstantial evidence has indicated that aflatoxin is involved in the aetiology of liver cancer1, but we have found that it is possible to investigate this relationship by measuring the urinary excretion of aflatoxin M1, which is the hydroxylated product of B1.

A SEARCH FOR PROGESTERONE IN HUMAN URINE
Acta Endocrinologica, 1965ABSTRACT The determination of testosterone in urine provides an easier means for the appreciation of androgenicity than plasma analysis. On this basis a search for progesterone in urine was made without success. Progesterone could not be detected by the gas chromatographic method used.

Multiple ribonucleases of human urine
Biochemistry, 1981Four major urine ribonuclease (RNase) activities, designated bands A-D, were identified by sodium dodecyl sulfate-polyacrylamide gel electrophoresis and activity staining. Bands A, B, and C have alkaline pH optima and display molecular weights of 31 000, 23 000, and 20 000, respectively, upon sodium dodecyl sulfate (NaDodSO4) gel electrophoresis and ...

The mucopolysaccharide of normal human urine
Clinica Chimica Acta, 1956Abstract Mucopolysaccharide has been demonstrated in human urine but its identity never determined. Acid mucopolysaccharide, precipitated from normal human urine by cetyl-trimethyl-ammonium bromide was purified after digestion with trypsin and papain to yield a homogeneous material.

Alpha-glucosidases in human urine
Clinica Chimica Acta, 1967Abstract Two α-glucosidases from human urine have been separated by means of Sephadex G-200 gel filtration and further purified by DEAE-Sephadex chromatography. Both enzymes hydrolyse maltose and glycogen to free glucose. Indirect evidence has been obtained of the possible occurrence of further α-glucosidases in human urine.

The excretion of sugars in human urine
Clinica Chimica Acta, 1984Normal humans excrete about 1 mmol of alditols mostly as mannitol and 1 mmol of neutral sugars chiefly allulose in a 24-h period.

Progesterone is conjugated in human urine
Clinica Chimica Acta, 1980The discovery of two previously unknown progesterone conjugates in human urine is presented. Urine from near-term pregnant women was applied to an anion exchange column and then eluted with an increasing concentration gradient of sodium chloride. Aliquots of collected fractions were subjected to four different treatments: (1) immediate extraction, (2 ...

Crithidia factors in human urine
Biochemical Medicine, 1974Abstract 7,8-Dihydrobiopterin is the major component of urinary activity for Crithidia fasciculata together with trace amounts of probably 5,6,7,8-tetrahydrobiopterin. Epileptics controlled by anticonvulsants and patients with rheumatoid arthritis have significantly lower levels of urinary Crithidia factor.

N'-methylnicotinamide in human urine
Biological Mass Spectrometry, 1981The presence of a hitherto unrecognized pyridine base, N'-methylnicotinamide, in human urine has been established by electron impact and field ionization mass spectrometry. The quantitative analysis was performed by gas chromatography and by gas chromatography mass spectrometry on extracts of alkalified urine.
