The importance of local circulatory regulation has gained in acceptance during the last few years. Recent studies in this laboratory have indicated that the nonapeptide bradykinin selectively constricts the arteriovenous anastomoses. Because the octapeptide angiotensin II may also participate in local regulation of blood flow, the digital vascular responses to arterial and venous injections of this substance were studied in 20 normotensive and hypertensive subjects resting in bed in an environmentally controlled room. Digital blood flow was measured by means of the digital rheoplethysmograph. This apparatus makes it possible to measure the volumes and rates of digital inflow, outflow, and
