    Description / Table of Contents: Zusammenfassung Sieben von 8 Patienten mit einem Phäochromocytom zeigten eine über die Norm erhöhte Plasma-Renin-Aktivität (〉3 ng/ml/3 h). Bei 4 der 7 Patienten mit Hyperreninismus konnte gleichzeitig auch ein abnorm hohes Plasma-Aldosteron nachgewiesen werden (〉120 pg/ml). Seitengetrennte Bestimmungen der Plasma-Renin-Aktivität im Nierenvenenblut zweier Patienten zeigten, daß als Ursachen des Hyperreninismus sowohl eine Verringerung der Nierendurchblutung durch Tumorkompression im Sinne eines Goldblattmechanismus als auch eine Stimulation der renalen Reninsekretion durch Katecholamine in Frage kommen können. Bei 2 unserer Patienten mit einem Phäochromocytom fand sich eine über die Norm gesteigerte Cortisolsekretion.
    Notes: Summary Seven of eight patients with pheochromocytoma showed elevated plasma renin activity (〉3 ng/ml/3 hr). Four of these seven patients simultaneously had abnormally high plasma aldosterone (〉120 pg/ml). It was found by selective determinations of plasma renin activity in both renal veins that two different mechanisms may be responsible for the observed hyperreninism. Firstly, the pheochromocytoma can lead mechanically to a reduction in renal blood flow inducing an increased renin secretion. Secondly, catecholamines are known to stimulate renin secretion. Two of the eight patients with pheochromocytoma showed an increased cortisol secretion.

    Notes: Summary Although a transitory maternal zinc deficiency has been shown to result in an increased cadmium-induced fetotoxicity, the results of the present investigation indicated that a maternal zinc deficiency apparently did not affect the placental transfer of cadmium. However, a zinc deficiency did alter the maternal distribution of cadmium. The increased cadmium fetotoxicity associated with a maternal zinc deficiency may be caused by a maternal alteration rather than a direct effect on the fetus. Further study is necessary prior to any definitive statement concerning the effects of a maternal zinc deficiency on cadmium. fetotoxicity.

    Fetal effects of cadmium in pregnant rats on normal and zinc deficient diets (1978)

    Notes: Summary This investigation has shown that not only the extent of fetal resorption and malformation but also the types of malformation seen in rats depend upon the strain used and day of gestation. Furthermore, the effects of zinc deficiency and cadmium administration on the fetus can be at least additive, as was seen for malformations. For fetal resorption, zinc deficiency potentiated the action of cadmium.

    Description / Table of Contents: Summary Percutaneous transluminal dilatation of a left sided renal artery stenosis was performed in a 61 year old patient with hypertension. Biochemical and hemodynamic activity of the renal artery stenosis was demonstrated by measurement of renal venous renin-activity and determination of renal plasma flow and of pre- and poststenotic blood pressure values. Shortly after the dilatation procedure hypertension disappeared and renal plasma flow increased. The described procedure might be an alternative method to renal vascular surgery.
    Notes: Zusammenfassung Bei einem 61jährigen Patienten mit renovasculärer Hypertonie bei linksseitiger arteriosklerotischer Nierenarterienstenose wurde eine perkutane transluminale Dilatation der Stenose vorgenommen. Die biochemische und hämodynamische Aktivität der Nierenarterienstenose wurde durch Messung der Plasmareninaktivität im Nierenvenenblut, Bestimmung des renalen Plasmaflusses und der prä- und poststenotischen Blutdruckwerte in der Nierenarterie belegt. Kurz nach der Dilatation der Stenose normalisierte sich der Blutdruck, und es kam zu einem Anstieg des renalen Plasmaflusses. Weitere Untersuchungen werden zeigen, ob die beschriebene Methode eine Alternative zur operativen Korrektur der Nierenarterienstenose bietet.

    Control of plasma aldosterone in diabetic patients with hyporeninemic hypoaldosteronism (1978)

    Description / Table of Contents: Summary In three patients with diabetes and hyporeninemic hypoaldosteronism changes in renin activity, plasma aldosterone and cortisol were examined under various conditions: orthostasis and intravenous furosemide, infusion of synthetic β1–24 ACTH on two consecutive days and diurnal variations in basal hormone fluctuations. Each patient showed unmeasurably low renin activity unresponsive to orthostasis and intravenous furosemide while plasma aldosterone was below normal range. Under ACTH-infusion only marked increases in aldosterone were observed in one patient whereas cortisol responded normally in all diabetics tested. Analysis of diurnal night day fluctuations (20.00–8.00) in plasma aldosterone and cortisol revealed a close and statistically significant relationship between both hormones in each of the three patients (p〈0.05–〈0.001). Variations in plasma aldosterone thus were mediated through changes in endogenous pituitary ACTH. Compared with normal controls however, diurnal aldosterone curves were set at a lower level. Our results demonstrate that a reduced sensitivity of the adrenal gland to ACTH is not responsible for the observed subnormal plasma aldosterone levels in these patients. Therefore, the lack of circulating angiotensin II seems to be the causative reason of hypoaldosteronism. The exact mechanism of undetectable renin activity in these patients remains unknown.
    Notes: Zusammenfassung Bei drei Patienten mit Diabetes mellitus und hyporeninämischem Hypoaldosteronismus wurden Veränderungen der Plasmareninaktivität, des Plasmaaldosteron- und Plasmacortisolspiegels unter folgenden Bedingungen geprüft: Orthostase und intravenöse Furosemidapplikation, Infusion von synthetischem β1–24 ACTH an zwei aufeinanderfolgenden Tagen, Tag-Nacht-Rhythmus der basalen Hormonplasmaspiegel. Alle Patienten zeigten eine nicht meßbare und durch Orthostase und Furosemid nicht stimulierbare Reninaktivität. Gleichzeitig wurden subnormale Aldosteronplasmakonzentrationen gemessen. Unter ACTH-Infusion zeigte nur ein Patient einen deutlichen Anstieg des Plasmaaldosterons, während das Plasmacortisol in allen drei Fällen normal stimulierbar war. Die statistische Analyse der Tag-Nacht-Schwankungen von Plasmaaldosteron und Plasmacortisol zeigte in jedem der Fälle eine enge und statistisch signifikante Beziehung zwischen beiden Hormonen (p〈0,05–〈0,001). Es ist somit anzunehmen, daß Schwankungen des Plasmaaldosterons durch Veränderungen der hypophysären ACTH-Ausschüttung verursacht wurden. Jedoch war im Vergleich zu Normalpersonen die Rhythmik des basalen Plasmaaldosterons auf einem tieferen Niveau eingestellt. Unsere Ergebnisse lassen den Schluß zu, daß bei diesen Patienten nicht eine verminderte Sensitivität der Nebennierenrinde auf ACTH für die beobachteten subnormalen Aldosteronspiegel verantwortlich ist. Ursache für den Hypoaldosteronismus scheint somit der Mangel an zirkulierendem Angiotensin II zu sein. Der genaue Mechanismus der nicht meßbaren Reninaktivität bei diesem Patienten bleibt unbekannt.

    Notes: Abstract Concentration factors (CF) of 54Mn for three aquatic species: green algae (Protococcoidal chlorella), Daphnia magna, and fathead minnows (Pimephales promelas) were determined following direct exposure to the isotope in solution. The maximum accumulation (CF = 911) in P. chlorella was reached at 48 hours of exposure; the maximum uptake (CF = 65) in Daphnia was reached at 8 hours of exposure; and the maximum accumulation (CF = 22.6) in fathead minnows was at 128 hours of exposure. The data indicate that 54Mn accumulation decreases with ascent up a theoretical aquatic food chain when water is the only source of contamination.

    Notes: Several long chain primary alcohols (saturated, monoolefinic and methyl branched) have been converted via their mesylates into various long chain alkylated aromatic compounds with basic character, and their mass spectra compared. The spectra of 2-alkylaminopyridines and to some extent those of 3-alkylaminopyridines exhibit most clearly the structure of the aliphatic chain, allowing the localization of branchings and double bonds.

    Description / Table of Contents: Thermolysis of Acetoxy-alkylbenzene and Hydroxy-alkylbenzene DerivativesThe thermolysis of long chain acetoxy-alkylbenzene and hydroxy-alkylbenzene derivatives at 340-350°C affords, probably via a radical reaction, products in which acetoxy or hydroxy groups and/or alkyl residues are substituted by hydrogen (tables 1, 2). The yields vary with type, number, and position of substituents on the benzene ring. The thermolysis of hydroxydialkylbenzene derivatives 14 and 20 gives in addition hydroxy-triaklylbenzene derivatives formed by transfer of alkyl radicals.
    Notes: Die Thermolyse von langkettigen Acetoxy-alkylbenzolen und Hydroxy-alkylbenzolen bei 340-350°C liefert in einer vermutlich radikalisch ablaufenden Reaktion Produkte, in denen Acetoxy-bzw. Hydroxygruppen und/oder Alkylreste durch Wasserstoff ersetzt sind (Tab. 1, 2). Die Ausbeuten sind von der Art, der Anzahl und der Stellung der Substituenten am Benzolkern abhängig. Die Thermolyse der Dialkyl-hydroxybenzole 14 und 20 ergibt zusätzlich Trialkyl-hydroxybenzole, die durch Übertragung von Alkyl-Radikalen entstehen.
