1 METHODS AND RESULTS: Ang II (6.25, 25, and 100 pmol/min) was infused alone and then together with sodium nitroprusside (4 micrograms/min) and phentolamine (40 micrograms/min) in eight healthy volunteers. Phentolamine angiotensinogen Homo sapiens
2 The percentage reduction in forearm blood flow produced by Ang II 100 pmol/min in the phentolamine-predilated vascular bed was significantly lower than that seen in the sodium nitroprusside-predilated forearm bed (28.1 +/- 2.9% versus 52.9 +/- 4.2%; P = .006). Phentolamine angiotensinogen Homo sapiens
3 Comparison of the rate of change of blood flow in response to quadrupling doses of Ang II during blockade of alpha-receptors with phentolamine and during nitroprusside administration was calculated from the mean slope of the regression line of log-transformed blood flow versus dose of Ang II. Phentolamine angiotensinogen Homo sapiens
