title: [Ethacrynic acid does not disrupt homeostatic reactions of the kidneys to hemodynamic shifts].
abstract: Arterial pressure and diuresis were determined in anesthetized dogs against the background of single (15 mg/kg) and continuous (5 mg/kg/rhr) intravenous administration of uregit (etacrylic acid). Acute hemodynamic shifts produced by compression of common carotid arteries, vena cava anterior, intravenous administration of ephedrine (1 mg/kg) or of sodium nitrite (3 mg/kg) were attended by an increased renal excretion of sodium, potasium and water in hypertension and their passage - in hypertension. Mechaninisms  governing the express regulation of the water and electrolytes homeostasis and their relation to the active transpor of sodium are considered. Arguments in favour of a conjecture as to the localization of the mechanism responsible for the express regulation of the electrolytes homeostasis in acute hemodynamic shifts are advanced.
