Abstract
- Infusions of hot and cold Hartmann's solution were given into the hepatic portal vein and inferior vena cava of conscious rabbits. Similar infusions were given into an ear vein as controls. The time integral of the displacement of brain temperature was measured. 2. There was no evidence for the presence of warm sensors in the inferior vena cava, portal vein, liver or hepatic vein, and no evidence for a concentration of cold sensors in the inferior vena cava. 3. There may be cold-sensitive elements in the portal vein or the tissue perfused by blood passing through it.
摘要
- 将热的和冷的哈特曼氏溶液注入清醒家兔的肝门静脉和下腔静脉。作为对照，将类似的溶液注入耳静脉。测量脑温位移的时间积分。2. 没有证据表明下腔静脉、门静脉、肝脏或肝静脉中存在温觉感受器，也没有证据表明下腔静脉中存在冷觉感受器集中的情况。3. 门静脉或由流经它的血液灌注的组织中可能存在冷敏元件。
