Urinary Organic Metabolites
Studies of gas chromatography/mass spectrometry (GC-MS) techniques carried out in 1994 on human clinical samples had already suggested a “potential for diagnosis and studies of metabolism in situ” . Researchers found that, when this technique is applied to blood or urine, it gives an insight into the infected host microbial metabolism . A more recent study (2002) on urinary organic metabolites,...
متن کاملUrinary metabolites of radioactive histamine.
This laboratory has previously shown that, when animals are injected with microgram amounts of high specific activity C4-histamine, at least three radioactive metabolic products can be demonstrated in the urine. Paper chromatograms of the urine in butanol80, ethanol 10, and ammonia 30 showed three radioactive peaks. The following information regarding their identity has been published. Peak 1 i...
متن کاملIdentification of urinary metabolites of isoprene in rats and comparison with mouse urinary metabolites.
Isoprene, a major commodity chemical used in production of polyisoprene elastomers, has been shown to be carcinogenic in rodents. Similar to findings for the structurally related compound butadiene, mice are more susceptible than rats to isoprene-induced toxicity and carcinogenicity. Although differences in uptake, and disposition of isoprene in rats and mice have been described, its in vivo bi...
متن کاملNitrazepam in premedication.
The sedative effects of nitrazepam in a dose of 5 mg and 10 mg have been compared with Mandrax, a combination of methaqualone 250 mg with diphenhydramine 25 mg. Studies were carried out in gynaecological patients undergoing minor surgical operations using the scoring system previously described. The degree of sedation obtained after administration of the two dose levels of nitrazepam was compar...
متن کاملPolymorphic acetylation of nitrazepam.
Nitrazepam is metabolized in part by nitro-reduction to an amine followed by acetylation. This acetylation step has been shown to be under the control of the same genetic polymorphism as sulphamethazine (syn: sulphadimidine).
