摘要: 为了寻找一种替代家兔热原试验的方法 ,最近我们对用THP 1细胞系检测热原的可行性进行了初步探索。其原理是 :将细菌内毒素标准品刺激THP 1细胞 6h后 ,用ELISA双抗夹心法测定其释放的内源性热原 (TNF α)。试验结果表明 :TNF α的量与内毒素的量在一定范围 (0 .32EU mL— 2 0 0EU mL)内有很好的相关性 ,两种不同来源的内毒素得到的结果相似。说明该方法作为替代家兔热原检查的新方法有一定的可行性

摘要: The pyrogen test is an important index of quality management relating to druggery injection and instillation and the current common methods are domestic rabbit test and Bacterial Endotoxins Test. Since there are shortcomings and limitations of resources in these two methods , it's necessary to look for another new substitute. We have done the preliminary study of the feasibility of the pyrogen test with domestic rabbit's blood plasm, human's plasm and THP 1. The principle is as follows: after incubating the standard sample of bacterial endotoxins, glycogen anti coagulation whole blood extracting from the healthy domestic rabbit, extralin anti congealable whole blood from healthy volunteers, THP 1 cells together, measure the releasing amount of TNF and IL 6 from cell gene by the method of ELISA as a endogenesis index judging the pro heat role of endotoxin. The results indicate: the blood rabbit's whole blood, human's whole blood, or THP 1cell, their releasing amount of TNF and IL 6 are closely connected with the amount of acting endotoxins within a certain range. Three methods have their own peculiarities and some feasibilities as a new substitute method for pyrogen test with domestic rabbit.

摘要: 目的　分析热原检查用家兔正常体温的动态变化。方法　按照有关规程对热原检查用家兔进行体温测定 ,并采用生物统计方法进行统计分析。结果　热原检查用家兔一年中正常体温 5— 7月份与 2— 4月份存在显著性差异 (P <0 0 5 ) ;二次用兔的正常体温平均值明显高于新兔的正常体温平均值 ,二者温差为 0 0 7℃ ,且存在显著性差异 (P <0 0 5 )。结论　热原检查用家兔正常体温随时间和使用状态而有所变化
