    Notes: Summary Cortisol-21-sulphate has been identified in the urine of three patients with Cushing's syndrome before and after total adrenalectomy (substitution with 200 mg F orally). The identification was based upon the following data: Identical behaviour of the standard cortisol-21-sulphate and the unknowns in two different paper chromatographic systems; positive methylene blue reaction and UV-contact-photogram; identical absorption spectra in concentrated sulphuric acid; correspondence with free cortisol of the steroid moiety liberated by dioxan solvolysis and formation of adrenosterone following treatment with chromic acid. The data support evidence that cortisol-21-sulphate may originate not only from the human adrenal gland but also from extra-adrenal sources, presumably the liver.

    Description / Table of Contents: Zusammenfassung Die Wirkung lokal applizierter Steroide und eines Dodecahydrophenanthrens auf die Talgdrüsen wurde mit Hilfe der gravimetrischen Bestimmung der Talgproduktion geprüft. Wenn der Testosteroneffekt gleich 1 gesetzt wurde, war der des 5α-Dihydrotestosterons 0,6 und der des 5β-Isomers 0,26. Epitestosteron zeigte bei Frauen keine Wirkung, bei einigen männlichen Probanden kam es zu einer deutlichen Steigerung der Sebumproduktion, die jedoch nicht signifikant war. Hinsichtlich einer Hemmung der Talgdrüsentätigkeit zeigten folgende Steroide keinen signifikanten Effekt: Retroprogesteron (Duphaston), 17α-Allylretrotestosteron, Allylestrenol, Δ1-6-chlororetroprogesteron. Dagegen verursachte das Nichtsteroid Ro 5-2537 [2-(1-Äthinyl-1-hydroxyäthyl)-7-oxo-1,2,3,4,4α,4β,5,6, 7,9,10,10α-dodecahydrophenanthren] bei allen Probanden eine signifikante Hemmung der Talgdrüsen.
    Notes: Summary The effects of topically applied steroids and of a dodecahydrophenanthrene were investigated by means of the sebaceous gland response. Compared with testosterone (= 1) the effects of 5α-dihydrotestosterone and 5β-dihydrotestosterone were found to be 0.6 and 0.26, respectively. Epitestosterone was ineffective in females, whereas in some males an increase in sebum production was observed. The following steroids showed no significant effects with regard to an inhibition of sebum production: Retroprogesterone (Duphaston), 17α-allyl-retrotestosterone, allylestrenol, Δ1-6-chloro-retroprogesterone. The nonsteroid Ro 5-2537 [2-(1-ethinyl-1-hydroxyethyl)-7-oxo-1, 2,3,4,4α,4β,5,6,7,9,10,10α-dodecahydrophenanthrene]-caused in all subjects a significant decrease in sebum production.

    Notes: Summary Testosterone sulphate has been isolated from the urine of a normal male subject. The characterization of the substance was based upon the following criteria: Identical Rf values of authentic testosterone sulphate and of the unknown compound in the paperchromatographic systemSi; positive methylene blue-reaction and UV contact photogram; identical absorption spectra in concentrated sulphuric acid. Following dioxan solvolysis, only testosterone has been detected. Epitestosterone could not been found.

    Description / Table of Contents: Summary A non-isotopic method for the determination of free and glucuronosid-conjugated testosterone in urine is described. Following hydrolysis withβ-glucuronidase the extract is purified on florisil. Testosterone is separated by chromatography in two thin-layer-chromatographic systems and in Bush B3 or BA. The hormone is quantitated as the isonicotinic acid-hydrazide. Possibly excreted epi-testosterone is not separated from testosterone. The mean excretion of testosterone in urine yielded the following figures: normal males 54 µg/24 hours, normal females 10 µg/24 hours. In two instances additional dioxan solvolysis liberated further amounts of testosterone from male urine, corresponding to 15 and 17 µg/24 hours.
    Notes: Zusammenfassung Es wird eine Methode zur Bestimmung des freien und des glucuronosid-konjugierten Testosterons im Urin beschrieben. Nach Hydrolyse wird der Extrakt an Florisil gereinigt und das Testosteron durch zweimalige Dünnschicht- und nachfolgende Papierchromatographie getrennt. Die quantitative Bestimmung erfolgt mit Hilfe der Isonicotinsäure-Hydrazid-Reaktion. Eventuell vorhandenes epi-Testosteron geht in die Reaktion mit ein. Die Spezifität und die Genauigkeit der Methode sind ausreichend gut, so daß der Zusatz von markiertem Testosteron nicht erforderlich ist. Die Testosteron-Ausscheidung betrug bei gesunden Männern im Mittel 54 µg/24 Std, bei gesunden Frauen im Mittel 10 µg/24 Std. In zwei Fällen konnte durch eine zusätzliche Dioxan-Solvolyse weiteres Testosteron in einer Größenordnung von 15 bzw. 17 µg/24 Std freigesetzt werden.
