Die C-17-Ketosteroidausschüttung nach Gaben von Äthanol und Wein
1955
Single or repeated doses of wine result in a statistically significant rise of excretion of C-17-Cetosteroids. After application of the same quantity of ethylalcohol, this effect was not seen. These results can be correlated with former observations on the changes of the nuclei-volumes of the zona fasciculata.
Ver�nderungen der Wasser- und Salzausscheidung sowie der Nierenstruktur w�hrend des 2.?10. Tages nach einmaliger intraven�ser Zufuhr von Chlormerodrin

Die renale Elektrolytausscheidung normaler und adrenalektomierter Ratten nach intraven�sen Salzinjektionen und ihre Beeinflussung durch Corticosteroi…
1959
Groups of normal rats of both sexes in moderate water diuresis received i.v. injections of 5 ml./kg, of hypertonic (5 times isoosmotic) solutions of sodium chloride, mannitol er sodium sulfate. The renal excretion of water, sodium, chloride and potassium in a 30 minute-period following this injection was measured. It was compared to control values obtained 40 minutes earlier in the same animals after an i.v. injection of isotonic glucose solution. All hypertonic solutions increased diuresis, natriuresis, chloruresis and kaliuresis. While the effects of mannitol and sodium chloride were comparable, sodium sulfate was more natriuretic and less chloruretic. The excretion of potassium after inj…
Die renale S�ure- und Ammonium-Ionen-Ausscheidung normaler und adrenalektomierter Ratten und ihre Beeinflussung durch Nebennierenrindenhormone
1959
The renal excretion of acid and ammonium ions after an oral load of monosodium-phosphate (1.2 mEq. per rat) was studied in groups of adrenalectomized er sham-operated rats, maintained on 0.9 per cent NaCI solution and water, on the 6th or 12th day after operation. Untreated groups were compared to groups receiving either Corticotropin (25 U./kg./day s.c.) or Cortisone acetate (12.5 mg./kg./day s.c.) er (7.5 mg./kg./day s.c.) or D,L-Aldosterone acetate Cortexone acetate (0.15 mg./kg./day s.c.) from the 3rd to the 12th day after opetarion. In sham-operated rats Cortisone increased H+ excretion and diuresis on the 6th day after operation (3rd day of treatment). This influence did not persist o…
Aufnahme und renale Ausscheidung von Wasser und Salzen bei freiem Nahrungs- und Trinkfl�ssigkeitsangebot; ihre Beeinflussung durch Adrenalektomie und…
1959
Water, sodium, potassium and chloride balances, food uptake and changes in body weight were determined in large groups of adrenalectomized or sham-operated rats having permanent access to water, 0.9 per cent saline and rat crackers. Measurements were done on the 5th to 8th day, or else on the 11th to 14th day after operation. From the 3rd day after operation the animals either received s.c. injections of 2.0 ml./kg. 0.9 per cent NaCl per day (controls) or of one of the following hormones: Corticotropin (25 U/kg. b.w./day), Cortisone acetate (12.5mg./kg./day), Cortexone acetate (7.5mg./kg./day) or D,L-Aldosterone acetate (0.15 mg./kg./day). Besides electrolyte balances, plasma concentrations…
Synthese, Verteilung und Ausscheidung von 14C markiertem 2-Phenyl-3-methyl-tetrahydro-1,4-oxazin (Preludin)
1958
A radioactive preludin preparation, C14 labelled on the 2-carbon of the tetrahydrooxazine ring, was injected into mice in doses of 100 mg/kg s.c. and rats in doses of 10 mg/kg i.v. The radioactivity of the tissues and excreta was followed for 48 hours. An activity concentration surpassing the average body concentration was obtained for a short time in the lungs and for a longer time in kidneys, liver and in the wall of stomach and small intestine. 95–99% of the total activity is found in the urine. The kidney excretion is virtually finished at the end of 8 hours; 1–5% appear after the 8th hour in faeces. No radioactivity was obtained from the expired CO2. The main excretion organs are kidne…

1956
An 13 Hypertonikern und 6 gesunden Personen wurden die Vergnderungen im funktionellen Zustand der BlutgefaBe der unteren Extremitaten nach Einspritzung yon isotonischer (1,8%) Magnesiumsulfatlosung in Dosen zu 5–25 cm3 und hypertonischer (10% und 25%) MagnesiumsulfatlSsung in Dosen yon 2–10 cm3 untersueht. Bei schnellem Einspritzen trat meistens Volumenverringerung der Extremitat ein, wahrend bei langsamem Einspritzen Vergroβerung oder Zweiphasenvergnderung erfolgte, die als Volumenverringerung und darauf folgende Volumenvergroβerung der Extremitat in Erscheinung trat. Die isotonische Losung verursacht entweder Volumenvergroβerung der Extremitat oder Zweiphasenveranderung — Verringerung und…
Die Ausbildung verschieden starker Stauungs�deme bei der Ratte und ihre Beseitigung durch Chlorothiazid
1960
1. After tying of the jugular veins a congestion edema of differing intensity was produced by oral loading of rats with varying amounts of saline. 2. Chlorothiazid (10 or 50 mg./kg. i.v.) given 24 hours after tying of the jugular veins increased the diuresis and sodium excretion to approximately the same values in edematous and normal animals. 3. The effect of chlorothiazid on renal excretion is not influenced by the severity of the edema and is not quantitatively related to reduction of edema.
