刺五加注射液致敏性物质筛选的初步研究

目的：评价刺五加注射液的过敏性,筛选刺五加注射剂中的致敏物质。方法：采用体内外方法同时评价刺五加注射液的过敏性,将被动皮肤过敏试验（PCA）方法进行改良,应用改良后的方法,以随机选取的三批刺五加注射液经冻干浓缩后与弗氏佐剂混合作为抗原,进行对大鼠的PCA试验,结合致敏后大鼠腹腔肥大细胞内外组胺量判断刺五加注射液的致敏性,采用PCA试验对致敏批次的刺五加注射液的致敏部位进行了初步筛选。结果：三批刺五加注射液中,有一批可引起大鼠产生阳性蓝斑过敏反应,致敏大鼠细胞组胺量升高,经PCA试验初步分析,醇沉部位可引起阳性过敏反应。结论：临床上出现的有过敏反应的某些批号的刺五加注射液可引起大鼠产生过敏反应,但由于动物之间的个体差异性以及临床用药缺乏合理性,未能将收集到的所有临床上发生过敏反应的刺五加注射液的过敏性检出,临床应用刺五加注射液的不良反应中,应考虑I型变态反应的存在,其致敏物质可能是由于刺五加注射液生产工艺中醇沉不完全,导致大分子物质残留所致。

Screening Allergens in Acanthopanax Senticosus Injection

Objective: To evaluate the allergy of Acanthopanax senticosus injection and screening allergens in the injection.Methods: In vivo and in vitro methods were used at the same time to evaluate the allergy of Acanthopanax senticosus injection.The passive cutaneous anaphylaxis(PCA) method was improved,three batches of Acanthopanax senticosus injections were randomly selected and freeze-dried,adjuvant and freeze-dried Acanthopanax senticosus injection as antigen,and the improved method was used to give rats PCA t...
