Abstract

Beta-glucuronidase and cathepsin D activity was measured in rabbit sera. A significant increase in beta-glucuronidase activity was found following the intravenous application of a high dose of the parent endotoxin. The enzyme liberating effect of endotoxins irradiated by 50, 100, and 150 kGy was much weaker. Enzyme assays also confirmed that, independent of the irradiation, radiodetoxified endotoxins retain their endotoxin tolerance inducing effect.

放射性解毒内毒素诱导溶酶体酶释放和耐受性。
测定兔血清中β -葡萄糖醛酸酶和组织蛋白酶D的活性。在静脉注射高剂量的母体内毒素后,发现β -葡萄糖醛酸酶活性显著增加。50、100、150 kGy辐照对内毒素的酶解作用较弱。酶分析也证实,不受辐照影响,放射线解毒内毒素仍保持其诱导内毒素耐受的作用。
