参麦注射液渗透压和溶血率现状的调查

目的：为做好参麦注射液安全性再评价工作提供数据参考。方法：渗透压测定采用冰点测定法,对样品原液及其稀释液进行渗透压测定,并计算与氯化钠注射液渗透压的比值;溶血率测定采用分光光度法,对样品原液及其稀释液进行溶血率测定。结果：渗透压测定,样品原液均为低渗溶液,渗透压值在96～180mOsmol/kg,1→4～1→8稀释后与氯化钠注射液渗透压比可达0.9;溶血率测定,样品稀释倍数在小于1→16时,样品均存在不同程度的溶血（溶血率〉5%）,1→32倍稀释时,溶血率均小于等于5%。结论：不同厂家生产的参麦注射液的渗透压和溶血率均存在一定的差异,建议增加渗透压和溶血率测定来控制其质量。

Investigation of osmotic pressure and hemolysis ratio in Shenmai Injection

Objective： To provide the data for re-evaluating the security of Shenmai Injection. Methods： Ice point method was used to determine the osmotic pressure of Shenmai Injection and its dilution solution. Ratio was calculated to NS. Spectrophotometry was utilized to measure the ratio of hemolysis. Results： All primary samples of Shenmai Injection were hyposmotic solution with osmotic pressure 96-180 mOsmol/kg. The ratio of the dilution（1→4 or 1→8）were up to 0.9. Different degrees of hemolysis occured when Shenmai Injection was diluted to less than 16 folds with the ratio of hemolysis more than 5%. But when Shenmai Injection was diluted to 32 folds, the ratio of hemolysis were less than 5%. Conelusion： There is obvious difference of osmotic pressure and hemolysis ratio among Shenmai Injection produced by different manufacturers. It was suggested that osmotic pressure and hemolysis ratio can be used to control the quality of Shenmai Injection.
