目的 :用细菌内毒素检查法检查胎盘组织注射液中的细菌内毒素。方法 :采用最大有效稀释法 ,解决胎盘组织注射液对鲎试剂的干扰作用。结果 :不经稀释直接测定 ,该药对鲎试剂具干扰作用 ;但经稀释 12 0、2 40倍即对鲎试剂无干扰作用。结论 :可用灵敏度 0 .12 5、0 .0 6EU/ml的鲎试剂检测此品中的细菌内毒素 Objective: To examine bacterial endotoxin in placental tissue injection by bacterial endotoxin test. Methods: The maximum effective dilution method was used to solve the interference effect of placental tissue injection on Tachypleus trichocarpa. Results: Direct determination without dilution, the drug has a disruptive effect on the 鲎 reagent; but diluted 12 0,2 ​​40 times that 鲎 reagent without interference. CONCLUSION: The bacterial endotoxin in this product can be detected by the limulus reagent with the sensitivity of 0.12 5,0. 06EU / ml
