| 中文摘要:目的 通过考察含糖平衡盐、替硝唑葡萄糖和氧氟沙星葡萄糖注射液对鲎试剂的干扰作用.探讨以细菌内毒素检查法中的凝胶法取代热原检查法检查含糖平衡盐等3种自制注射液细菌内毒素限值的可行性.方法 采用动态浊度法,用EDS-99细菌内毒素测定仪对含糖平衡盐、替硝唑葡萄糖和氧氟沙星葡萄糖注射液进行干扰试验并用凝胶法进行验证.结果 用两个厂家生产的鲎试剂以动态浊度法检测3个不同批号的含糖平衡盐和替硝唑葡萄糖注射液,样品不经稀释,其细菌内毒素回收率均在50%～200%范围内,标准曲线的相关系数绝对值大于0.980,表明含糖平衡盐、替硝唑葡萄糖注射液对鲎试剂反应无干扰作用,3批样品同时用凝胶法检查,其结果均为阴性;氧氟沙星葡萄糖注射液对鲎试剂有干扰,稀释4倍可消除干扰.结论 含糖平衡盐、替硝唑葡萄糖注射液对鲎试剂反应无干扰作用,凝胶法可作为生产含糖平衡盐和替硝唑葡萄糖注射液时日常检查其细菌内毒素限值的方法;氧氟沙星葡萄糖注射液稀释4倍后可用凝胶法检查. |

| Abstract:Objective To approach the feasibility of replacing pyrogen test with bacterial endotoxin test (BET) by analysing the interference of balance salts containing glucose, tinidazole and glucose, ofloxacin and glucose injection to limulus amebocyte lysate (LAL).Methods The kinetic turbidimetric assay (KTA) was used to determinate the bacterial endotoxin and did an interfering test by using of the EDS-99 bacterial endoxin systems, in the same time gel-clot method was used to test and verify.Results The experiment shows the balance salts containing glucose, tinidazole and glucose injection have no interference to LAL, ofloxacin and glucose injection has no interference to LAL when is diluted four times.Conclusion The gel-clot method can be used as a daily examination to analyse balance salts containing glucose, tinidazole and glucose,ofloxacin and glucose injection. |
