Abstract

To clarify the possible role of TNF and IL-1 in endotoxic shock, the lethality of rTNF (human and murine) and IL-1 in adrenalectomized mice was studied. Adrenalectomy, which has long been known to increase the susceptibility to endotoxin, rendered mice susceptible to TNF and IL-1 in terms of mortality. The lethality of endotoxin, TNF, or IL-1 was totally prevented by pretreatment with dexamethasone (minimal effective dose, 0.3 mg/Kg) but not by ibuprofen (10 mg/Kg).

摘要

为阐明肿瘤坏死因子(TNF)和白细胞介素-1(IL-1)在内毒素休克中可能发挥的作用,研究了重组TNF(人源和鼠源)及IL-1对肾上腺切除小鼠的致死性。肾上腺切除术长期以来被认为会增加对内毒素的易感性,就死亡率而言,使小鼠对TNF和IL-1易感。地塞米松(最小有效剂量,0.3毫克/千克)预处理可完全预防内毒素、TNF或IL-1的致死性,但布洛芬(10毫克/千克)预处理则不能。
