摘要: 目的:对低分子肝素(LMWH) 生物活性测定中几种不同的实验设计进行比较。方法:对LMWH 生物活性测定采用酶促反应的分光光度法, 进行了量反应平行线实验设计中4°4 法与4°3法、3°4 法、3°3 法的比较。结果:量反应平行线实验设计中4°4 法与4°3 法、3°4 法、3°3 法结果相似, 其差异无统计学意义(P>0.05) 。结论:采用酶促反应的分光光度法对LMWH 的效价测定, 应采用量反应平行线法实验设计;在符合标准规定前提下, 4°4 法与4°3 法、3°4 法、3°3 法不同剂量组实验设计都可应用。

Abstract: AIM: To compare several experimental designs for detecting the bioactivity of low-molecularweight heparin (LMWH).METHODS: Chromogenic assay was used for detecting the bio-activity of LMWH by comparing the 4°4 method to 4°3, 3°4 or 3°3 method in quantity response parallel line design.RESULTS: In bioassay of LMWH with the quantity response parallel line analysis, there had no statistical difference (P>0.05) between 4°4 method with 4°3, 3°4 or 3°3 method.CONCLUSION: Quantity response parallel line design could be used in validation of the chromogenic assays for the potency assessment of LMWH.In parallel line design, 4°4, 4°3, 3°4 or 3°3 method of different dose groups all could be used according to the standard for LMWH.
