title: Effect of exogenous angiotensin-II on local blood flow in kidneys with neoplasm. Experiments in the rat.
abstract: The effect of angiotensin-II on the local renal blood flow and arterial blood pressure was investigated in the rat with the H2 gas washout technique. Increasing intravenous infusion rates gave a decreasing blood flow and increasing blood pressure, renal vascular resistance being close to proportional to the log of infusion rate. In kidneys with experimental neoplasm, the flow reduction was proportionally less in the tumor than in intact renal tissue. The respective flow levels were maintained for 10 to 45 min without tendency to change.
