    Description / Table of Contents: Zusammenfassung Die Metabolitprodukte von Chlormethiazol wurden aus der Leber extrahiert und mittels Dünnschichtchromatographie isoliert. Es wurden Chlormethiazol und drei andere Produkte nachgewiesen, wobei ein Produkt schon vorher als 4-Methyl-5-β-hydroxy-ethylthiazol identifiziert wurde. Die Strukturformeln für die zwei anderen Produkte wurden vorgeschlagen. Ein vierter Metabolit (4-Methyl-5-thiazolessigsäure) wurde aus Urin erhalten. Die Proben wurden durch Gaschromatographie, Gaschromatographie-Massenspektrometrie und durch hochauflösende Massenspektrometrie analysiert.
    Notes: Summary The metabolic products of chlormethiazole were extracted from liver and isolated by thin layer chromatography. Chlormethiazole and three other products were obtained. One of these was identified earlier as being 4-methyl-5-β-hydroxy-ethylthiazole and now structures are proposed for the other two. A fourth metabolite, 4-methyl-5-thiazoleacetic acid, was formd in urine. The samples were analyzed by gas chromatography, gas chromatography-mass spectrometry and by high resolution mass spectrometry.

    Notes: Summary Gas-chromatographic odor-assay techniques have been used to study vaginal odors. An improved version of this technique was applied to compare the efficacy of a suppository containing phenylmercuric acetate, a feminine douche preparation, and a conventional vinegar douche in reducing the concentrations of malodorants in the vaginal vapors of ten normal women. Seven malodorants occurred frequently in vaginal vapors; seven more were noted less frequently, and additional ones occurred occasionally. A reduction in the malodorant concentrations was observed with all treatments, but this effect reached acceptable statistical probability levels,p〈0.05 (95% confidence levels), consistently only for the suppository. The effect of the phenylmercuric acetate suppository on the concentration of vaginal malodorants was statistically valid at 2, 6, and 10 hours after its use. In the case of the douche preparation, the degree of reduction in the malodorant concentrations did not reach statistical significance. A Sign Test, however, on the frequency of the malodorant concentration decreases as compared with the frequency of malodorant concentration increases indicated statistical significance for the decreases at 6 and 10 hours after the use of the douche preparation. The total number of malodorants per sample likewise tended to decrease with the various treatments, but this effect reached statistical significance only for the suppository 6 and 10 hours after the treatment.
