已知革兰氏阴性(G~-)菌表面释放的脂多糖(LPS、内毒素)是G~-菌血症的主要致病和致死成分。单用抗生素治疗,死亡率达30～50%,部分原因是细菌虽被杀灭,但遗留的LPS毒性仍在。投用抗内毒素特异性丙种球蛋白可以减少其致病性和致死性。作者报道 It is known that lipopolysaccharide (LPS, endotoxin) released on the surface of Gram-negative bacteria is the main pathogenic and lethal component of G-bacteremia. With antibiotic alone, the mortality rate is 30-50%, partly because bacteria are killed but the LPS remains. Administration of anti-endotoxin-specific gamma globulin can reduce its pathogenicity and lethality. The authors report
