Angiotensin in a dose of 0.5 to 1.0 microgran injected into the renal artery of healthy kidneys initially decreased renal blood flow and increased the appearance time and mean transit time of dye and contrast medium as examined by a dye dilution technique and angiography. The initial phase is followed by a reactive hyperemia. The increased vascular resistance is probably localized peripherally on the arterial side of the vascular tree. Optimum dose is 0.5 to 1.0 microgram angiotensin in diagnosis of renal tumours. Optimum interval between drug administration and angiography is 10 to 60 s.
将剂量为0.5至1.0微克的血管紧张素注入健康肾脏的肾动脉，最初会使肾血流量减少，并通过染料稀释技术和血管造影检查发现，染料和造影剂的出现时间及平均通过时间增加。初始阶段之后会出现反应性充血。血管阻力增加可能位于血管树动脉侧的外周。在肾肿瘤诊断中，血管紧张素的最佳剂量为0.5至1.0微克。给药与血管造影之间的最佳间隔时间为10至60秒。
