摘要
目的:探讨葛根素注射液引起急性溶血的机制。方法:用Beagle犬和豚鼠进行葛根素注射液的体内外溶血试验如下:制剂的溶媒丙二醇和pH值对体外Beagle犬红细胞的溶血作用;静脉注射葛根素对豚鼠超氧化物歧化酶(SOD)、丙二醛(MDA)的含量及致敏豚鼠红细胞溶血率的影响;葛根素对Beagle犬和豚鼠红细胞的体外溶血作用和细胞形态的影响。结果:葛根素注射液最大浓度时(10g/L)的pH值为4.48,可致Beagle犬红细胞溶血;而同pH值的0.9%氯化钠注射液未见引起Beagle犬红细胞溶血。含5%和10%丙二醇的葛根素注射液可引起Beagle犬红细胞溶血;单纯5%和10%丙二醇溶液未见引起Beagle犬红细胞溶血。豚鼠静脉注射葛根素注射液组与0.9%氯化钠组比较,红细胞膜MDA含量明显下降(P<0.01),未见引起氧化性溶血。葛根素注射液致敏豚鼠后与致敏前比较,未见红细胞溶血率升高,未见抗原抗体复合物产生。豚鼠静脉注射葛根素注射液能引起红细胞皱缩甚至破裂。体外非免疫性溶血试验显示葛根素注射液能直接致Beagle犬和豚鼠红细胞溶血,且与剂量相关。结论:葛根素注射液引起的溶血属于药物非免疫性溶血,可能与葛根素注射液直接作用于红细胞,引起红细胞稳定性改变有关。
Objective:To study the mechanism of hemolysis induced by puerarin injection. Methods: Hemolysis tests in vitro and vivo were performed with puerarin injection in Beagle dogs and guinea pigs as follows : the hemolytic effects of solvent propylene glycol and pH value of the preparation on red cells of Beagle dogs ; the effects of IV puerarin on the levels of SOD and MDA of guinea pigs, and hemolytic rates of red cells of sensitized guinea pigs ; and the influences of puerarin injection on hemolytic effects and morphological change of red cells of Beagle dogs and guinea pigs. Results: The hemolysis of Beagle dogs' red cells occurred with puerarin in maximum concentration ( 10 g/L) and pH 4.48, and it did not occur with sodium chloride 0.9%, which had the same pH value as the former. The hemolysis of Beagle dogs' red cells occurred with puerarin injection containing propylene glycol 5% or 10% , and it did not occur with propylene glycol solution 5% or 10%. The level of MDA was marked decreased in the puerarin injection group compared with the sodium chloride 0, 9% group (P 〈0. 01 ). The hemolytic rates of red cells was not increased, and antigen-antibody complex was not found in guinea pigs before and after sensitization with puerarin injection. Red cells of guinea pigs were shrunk or broken. The non-immune hemolysis tests in vitro showed that the hymolysis of red cells of Beagle dogs and guinea pigs occurred with puerarin injection, and it was related to the dosage. Conclusion: Puerarin injection-induce hemolysis is a non-immue one, it may relate to its direct action on red cells and lead to changes in the stability of cells.
