3 techniques for the measurement of testicular blood flow in anesthetized adult rats were compared. Direct measurement of testicular venous outflow yielded values more than 3 times lower than those obtained Xe-133 clearance and radioactive microsphere techniques due to the surgical procedures involved in spermatic venous cannulation. There was an agreement between flow values obtained with Xe-133 clearance (17.8 +/- 3.5 ml/100 g X min) and radioactive microspheres (19.9 +/- 5.5 ml/100 g X min). A homogeneous distribution of microspheres to different segments of the testis indicates that Xe-133 clearance is an adequate technique for testicular blood flow measurements. However, for some experimental purposes the radioactive microsphere technique is more versatile than Xe-133 clearance because of its capacity of measuring several organ flows simultaneously.
比较了3种测量麻醉成年大鼠睾丸血流量的技术。由于精索静脉插管所涉及的外科手术，直接测量睾丸静脉流出量得到的值比用Xe - 133清除法和放射性微球技术获得的值低3倍以上。用Xe - 133清除法（17.8±3.5 ml/100 g×分钟）和放射性微球法（19.9±5.5 ml/100 g×分钟）获得的血流量值之间具有一致性。微球在睾丸不同节段的均匀分布表明，Xe - 133清除法是测量睾丸血流量的一种合适技术。然而，对于某些实验目的，放射性微球技术比Xe - 133清除法更通用，因为它能够同时测量多个器官的血流量。
