Abstract

In anesthetized dogs total tongue blood flow and its distribution to mucosa and muscle capillaries and to arteriovenous anastomoses (AVA) was determined by combining venous outflow measurements with the radioactive microsphere technique. Local temperature changes of the tongue surface in the physiological range revealed an inverse relationship between lingual blood flow (8.6--30.4 ml . min-1) and tongue surface temperature (40.5 to 27.7 degrees C). The temperature dependent changes of tongue blood flow were exclusively due to changes of AVA blood flow (6.3--21.4 ml . min-1).

摘要

在麻醉犬中,通过将静脉流出量测量与放射性微球技术相结合,测定了全舌血流量及其在黏膜、肌肉毛细血管和动静脉吻合支(AVA)中的分布。舌表面在生理范围内的局部温度变化显示,舌血流量(8.6 - 30.4毫升·分钟⁻¹)与舌表面温度(40.5至27.7摄氏度)呈负相关。舌血流量随温度的变化完全是由于AVA血流量的变化(6.3 - 21.4毫升·分钟⁻¹)所致。
