Eglin C is a polypeptide inhibitor of the neutral proteases elastase and cathepsin G. We have investigated its action in traumatic shock in rats. Eglin C (2 mg/kg) given following trauma prolonged survival time from 2.3 +/- 0.5 h to 3.6 +/- 0.4 h (p less than 0.05) in traumatized rats. Although eglin C treatment had no significant effect on the increase in plasma cathepsin D activity, eglin C administration significantly blunted plasma myocardial depressant factor (MDF) accumulation, 54 +/- 3 vs 79 +/- 8 U/ml (p less than 0.02). Our findings indicate a potential role for neutral proteases in toxic factor formation.
埃格林C是一种中性蛋白酶弹性蛋白酶和组织蛋白酶G的多肽抑制剂。我们已经研究了它在大鼠创伤性休克中的作用。创伤后给予埃格林C(2毫克/千克)可使创伤大鼠的存活时间从2.3±0.5小时延长至3.6±0.4小时(p<0.05)。尽管埃格林C治疗对血浆组织蛋白酶D活性的增加没有显著影响,但给予埃格林C可显著抑制血浆心肌抑制因子(MDF)的积累,分别为54±3与79±8 U/ml(p<0.02)。我们的研究结果表明中性蛋白酶在毒性因子形成中具有潜在作用。
