【摘要】 采用游离血红蛋白直接测定法即溶血率测定法 (根据 ISO/ TR74 0 5 )和氰化高铁血红蛋白法 (根据 ISO10 993- 4 )测定了羟基磷灰石 (陶瓷 )和胶原 (高分子材料 )的溶血性能 ,结果提示这两种方法的结论是一致的 ,且氰化高铁血红蛋白法较血红蛋白直接测定法有灵敏、稳定、可比性好等优点 ,值得推广应用。但它存在着一些标准中尚未明确规定的问题。作者在大量试验和不违背标准原则的基础上提出了一些改进意见 ,使它更具有可操作性 ,以便于标准化评价生物材料的溶血性能更多还原

【Abstract】 In this study, two methods——the supernatant hemoglobin spectrophotometry, i.e. hemolysis percentage measurement(according to ISO/TR 7405) and the hemiglobincyanide measurement(according to ISO 10993-4)——were used to assay the hemolytic properties of hydroxyapatite(bioceramics) and collagen (polymer). The results showed that the conclusions drawn from using the two methods were basically consistent, and the latter was more sensitive, stable and comparable. However, some of the procedures in the hemiglobincyanide method were not defined in details. So based on our experiments we have offered some suggestions and improvements, which do not deviate from ISO and ASTM standards, for hiher practicability of usig it in standardizing the evaluation of the hemolytic properties of biomaterials. Hemiglobincyanide measurement is worthy of wider application.更多还原
