Abstract

Treatment with glucagon in addition to blood transfusion was compared with blood transfusion alone after one hour of hemorrhagic shock in the rat. In liver tissue Na+ increased and K+ decreased during haemorrhagic shock. After treatment the initial values were restored equally in both groups within ten minutes. Incubation of liver slices in cold Krebs' solution resulted in a pronounced increase in Na+ and decrease in K+, the values being partially restored to initial levels after subsequent incubation at 37 degrees. Thirty minutes after treatment the liver slices obtained from rats given glucagon showed a more normal ion composition after leaching and rewarming than slices from rats not given glucagon. ATP decreased and glucose and lactate increased in liver tissue during hemorrhagic shock. These variables were partially restored 30 minutes after treatment. No difference between the treatment groups was noted. Animals trreated with glucagon were, however, more efficient in reducing the elevated blood lactate level. The results suggest that the use of glucagon in the treatment of hemorrhagic shock might be of benefit for cellular function in the liver.

摘要

在大鼠失血性休克一小时后,将胰高血糖素联合输血治疗与单纯输血治疗进行了比较。在失血性休克期间,肝脏组织中的钠离子增加而钾离子减少。治疗后,两组在十分钟内均将初始值同等程度地恢复。将肝切片置于冰冷的克雷布斯溶液中孵育会导致钠离子显著增加而钾离子减少,随后在37摄氏度孵育后,这些值会部分恢复到初始水平。治疗30分钟后,与未给予胰高血糖素的大鼠相比,给予胰高血糖素的大鼠的肝切片在浸出和复温后显示出更正常的离子组成。在失血性休克期间,肝脏组织中的三磷酸腺苷(ATP)减少,葡萄糖和乳酸增加。治疗30分钟后,这些变量得到部分恢复。未观察到治疗组之间存在差异。然而,用胰高血糖素治疗的动物在降低升高的血乳酸水平方面更有效。结果表明,使用胰高血糖素治疗失血性休克可能对肝脏的细胞功能有益。
