[The effect of exogenous adrenaline and angiotensin II on the resistance vessels of the cat kidney].
In experiments with perfusion of the renal vessels with isotonic saline solution, the ability of angiotensin-II to activate the smooth muscle cells of these vessels was shown: both by direct myotropic action and in an indirect way - by catecholamines. Obvious tachyphylaxis is characteristic only for the direct myotropic effect of angiotensin-II. The data obtained suggest that the direct effect of angiotensin-II is selective for certain intrarenal vessels, while indirect action is more universal.
