[Variants in the catecholamine effect on renal hemodynamics].
It was shown in experiments on dogs that intravenous injection of adrenaline or noradrenaline in a dose of 2 microgram/kg per min was accompanied by an increase of resistance of the renal vessels with unchanged general renal circulation, and administration of adrenaline against the background of obsidan action--by an increase of resistance and reduction of blood flow, and--against the background of phentholamine action--by a reduction of resistance with unchanged circulation. On the basis of these data and those obtained by the author earlier a supposition is put forward on a possible mechanism of a combination of functions in the systems of circulation and excrection in the control of general water-salt homeostatis in extraordinary hemodynamic shifts with the participation of the humoral factor--renin-angiotensine system.
