To clarify the relation of endotoxaemia to hypoglycaemia and consequent death in acute hepatic failure, the interrelationship between the degree of hepatic injury, blood glucose level and mortality following endotoxaemia were examined in streptozotocin-induced diabetic and nondiabetic rats. Endotoxin hepatotoxicity was not enhanced in diabetic state. Blood glucose level was markedly reduced after endotoxin administration in the nondiabetic rats, and the reduction of blood glucose level closely correlated with the degree of hepatic injury (serum transaminase activities), namely, the more severe the hepatic injury, the lower the blood glucose level. Hypoglycaemia due to endotoxaemia occurred also in the diabetic rats when the hepatic injury was severe, but the reduction of blood glucose level was slight when it was mild. The mortality for endotoxaemia in diabetic rats was significantly lower than that in the nondiabetic rats. These experimental data suggest that endotoxaemia may play a role in the development of hypoglycaemia in acute hepatic failure, and that the diabetic state may lower the mortality for endotoxaemia.
为阐明内毒素血症与急性肝衰竭时低血糖及随后死亡之间的关系,我们在链脲佐菌素诱导的糖尿病大鼠和非糖尿病大鼠中研究了肝损伤程度、血糖水平与内毒素血症后死亡率之间的相互关系。糖尿病状态下内毒素肝毒性并未增强。非糖尿病大鼠给予内毒素后血糖水平显著降低,且血糖水平的降低与肝损伤程度(血清转氨酶活性)密切相关,即肝损伤越严重,血糖水平越低。当肝损伤严重时,糖尿病大鼠也会因内毒素血症发生低血糖,但肝损伤轻微时血糖水平降低幅度较小。糖尿病大鼠内毒素血症的死亡率显著低于非糖尿病大鼠。这些实验数据表明,内毒素血症可能在急性肝衰竭低血糖的发生中起作用,且糖尿病状态可能降低内毒素血症的死亡率。
