    Der Einfluß von Lithiumchlorid auf die Blutdruckwirkung von Renin, Angiotensin und Noradrenalin bei Ratten (1967)

    Description / Table of Contents: Summary The blood pressure effect of angiotensin and renin is strongly decreased in rats treated with lithiumchloride, the effect of norepinephrine is only little diminished. In the aorta stripe preparation of lithium treated rats a reduced contraction by angiotensin is also observed. The contraction by norepinephrine is equal compared with the control group. The results demonstrate the influence of intracellular sodium concentration in the smooth vascular muscles for the blood pressure effect of angiotensin.
    Notes: Zusammenfassung Bei Ratten ist nach Lithiumverabreichung die Blutdruckwirkung von Angiotension und Renin stark, die von Noradrenalin nur gering abgeschwächt. Am isolierten Aortenpräparat von lithiumvorbehandelten Ratten ist die durch Angiotensin ausgelöste Kontraktion ebenfalls deutlich, die Kontraktion nach Noradrenalin dagegen gegenüber der Kontrollgruppe nur gering vermindert. Die Befunde sprechen dafür, daß die Blutdruckwirkung von Angiotensin von der Natriumkonzentration in der glatten Muskelzelle abhängig ist.

    Zur Regulation der Reninsekretion durch Angiotensin (1967)
    Springer

    Description / Table of Contents: Summary In 6 out of 11 normotensive humans renin activity in peripheral venous plasma is decreased by 40% of the praeinfusion level after an angiotensin infusion continuing 30–60 minutes and raising diastolic blood pressure by 20 mm Hg. In 4 out of 8 patients with secondary aldosteronism or adrenal insufficiency and 4 out of 16 hypertensive patients plasma renin activity is increased by angiotensin infusion. Norepinephrine in pressor doses causes in part a decrease of plasma renin activity in patients with secondary aldosteronism or adrenal insufficiency and an increase in the normotensive and hypertensive groups. The negative feed back mechanism between angiotensin level in bloodplasma and renin secretion is discussed.
    Notes: Zusammenfassung Die Reninaktivität im peripheren Venenblut sinkt nach einer intravenösen Infusion von Angiotensin in Dosen, die für 30–60 min einen diastolischen Blutdruckanstieg von 20 mm Hg aufrechterhalten, bei 6 von 11 Gesunden um mehr als 40% der Ausgangswerte ab. Bei 4 von 8 Patienten mit sekundärem Aldosteronismus oder M. Addison sowie 4 von 16 Hochdruckkranken führt Angiotensin dagegen zu einem Anstieg des Plasmarenins bis auf das Doppelte. Nach einer pressorischen Noradrenalin-infusion ist die Plasmareninaktivität beim sekundären Aldosteronismus und M. Addison vermindert, bei Gesunden und Hochdruckkranken erhöht. Die Befunde werden in bezug auf einen direkten negativen Rückkoppelungsmechanismus zwischen Angiotensinkonzentration im Blut und Reninsekretion erörtert.

    Effect of the resonance parameter on a chemical reaction subjected to ultrasonic waves (1967)

    Notes: Experimental results are presented which indicate that the application of a fixed intensity of ultrasonic waves to a water-tetrachloride solution containing dissolved air provides yields of chlorine varying from zero to maximum simply as a function of the liquid height in the capillary above the transducer. The difference in heights of the liquid between zero and maximum yields is found to be equal to one-quarter the wavelength of the ultrasonic wave in the liquid. A mathematical model to explain this phenomenon is presented.
