The blood flow of the sinus mucosa was studied in 11 New Zealand White rabbits. Their body weight averaged 3.5 kg. The blood flow determinations were performed during neurolept anaesthesia with continuous blood pressure recording. The blood flow in the sinus mucosa and septum, as well as in other organs, was determined both with Sn113-labelled microspheres and with Rb86Cl. Cardiac output as determined with the microsphere method was 146 +/- 36 ml X min-1 X 1000 g-1 body weight. There was a good correlation between the blood flow values obtained with the two methods. The blood flow in the sinus mucosa was 0.58 +/- 0.41 ml X min-1 X g-1 when measured with microspheres and 0.43 +/- 0.34 ml X min-1 X g-1 with the Rb86Cl technique. In the septal mucosa the corresponding values were 0.42 +/- 0.20 ml X min-1 X g-1 and 0.49 +/- 0.43 ml X min-1 X g-1 respectively.
对11只新西兰白兔的鼻窦黏膜血流情况进行了研究。它们的平均体重为3.5千克。在神经安定麻醉期间进行血流测定，并持续记录血压。使用Sn113标记的微球和Rb86Cl测定鼻窦黏膜、鼻中隔以及其他器官的血流。用微球法测定的心输出量为146±36毫升×分钟-1×1000克-1体重。两种方法所获得的血流值之间存在良好的相关性。用微球测量时，鼻窦黏膜的血流为0.58±0.41毫升×分钟-1×克-1，用Rb86Cl技术测量时为0.43±0.34毫升×分钟-1×克-1。在鼻中隔黏膜中，相应的值分别为0.42±0.20毫升×分钟-1×克-1和0.49±0.43毫升×分钟-1×克-1。
