    Description / Table of Contents: Zusammenfassung Vergleichende Daten über Glutathionperoxidase (GSH-Px)-Aktivität der Erythrozyten, Serum-Cholesterin und Serum-Fettsäuremuster von indischen Emigranten und Dänen werden dargestellt. Die GSH-Px-Aktivität in Erythrozyten indischer Emigranten wurde im Vergleich zu der von Dänen, bei Verwendung von t-Butylhydroperoxid als Substrat, signifikant erhöht. Auch bei Verwendung dreier Peroxide, nämlich Wasserstoffperoxid, Cumenhydroperoxid sowie t-Butylhydroperoxid, wurde eine signifikante Korrelation (R 0,9) in der indischen Gruppe gefunden. Eine solche Korrelation konnte jedoch bei der dänischen Gruppe nicht festgestellt werden. Der Serum-Cholesteringehalt lag bei der indischen Gruppe signifikant niedriger als bei der dänischen Gruppe. Auch die Gesamtfettsäuren-Muster des Serums beider Gruppen unterschieden sich beträchtlich.
    Notes: Summary A comparative data on erythrocyte glutathione peroxidase (GSH-Px) activity, serum cholesterol and serum fatty acid pattern between Indian immigrants and Danes have been presented. The erythrocyte GSH-Px activity in the Indian immigrants has been found to be significantly increased as compared to that in the Danish group when t-buthylhydroperoxide was used as a substrate. Also a significant correlation (R ≤ 0.9) was found in the GSH-Px activities in the Indian group with the three peroxides, viz., hydrogen peroxide, cumene hydroperoxide and t-butylhydroperoxide, used. This correlation was, however, missing in the Danish group. Serum cholesterol was found to be significantly lower in the Indian group as compared to the Danes. Also total serum fatty acid patterns between the two groups differed considerably.

    Notes: Abstract The bromination of crotonic acid by N-bromosuccinimide (NBS) is first order with respect to crotonic acid and zero order with respect toNBS and the rate of the reaction changes linearly with hydrogen ion concentration. The thermodynamic parameters have also been calculated.

    Description / Table of Contents: Summary A relatively simple procedure for the isolation and determination of the prostaglandins present in human seminal fluid is described. It involves preliminary chromatographic purification of these compounds from the major non-prostaglandin impurities followed by their total elution in one solvent (one-step elution). The prostaglandins thus obtained were almost free from other lipids and were further resolved into prostaglandin-groups and individual prostaglandins by repeated thin-layer chromatography. Data are also presented for prostaglandin contents of fresh semen samples from five individuals and results compared with those from the stored samples.
    Notes: Zusammenfassung Das Verfahren umfaßt eine chromatographische Abtrennung der Verbindungen von den hauptsächlichsten Verunreinigungen und die Gesamtelution mit einem Lösungsmittel. Die von anderen Lipiden fast völlig freien Prostaglandine werden durch wiederholte Dünnschicht-Chromatographie in Gruppen und Einzelverbindungen getrennt. Werte werden angegeben über die Prostaglandingehalte von frischem im Vergleich zu gelagertem Sperma.

    Description / Table of Contents: Summary A micro method for the determination of olefinic unsaturation in organic compounds has been developed. 2–10 mg sample dissolved in acetic acid is reacted with a known excess of N-bromosuccinimide at room temperature and the excess reagent is back titrated iodometrically. The maximum deviation in the results is ±2%. The compounds containing electron withdrawing groups close to the C=C site are not reactive and hence could not be determined by this procedure.
    Notes: Zusammenfassung 2–10mg der Probe werden in Essigsäure gelöst, mit überschüssigem Reagens versetzt und der Überschuß jodometrisch zurücktitriert. Der maximale Fehler der Ergebnisse beträgt ±2%. Verbindungen, die benachbart zur C=C-Doppelbindung elektronenentziehende Gruppen enthalten, können nicht analysiert werden.
