目的:研究不同類(lèi)別及廠家的聚山梨酯80直接刺激肥大細(xì)胞RBL-2H3脫顆粒的作用,為建立完善的注射用輔料引發(fā)類(lèi)過(guò)敏反應(yīng)的篩選評(píng)價(jià)體系提供依據(jù)。方法:以不同劑量的聚山梨酯80處理RBL-2H3細(xì)胞,測(cè)定β-氨基己糖苷酶釋放量,并通過(guò)MTT法進(jìn)一步研究有脫顆粒作用的受試物對(duì)RBL-2H3細(xì)胞的毒性作用。結(jié)果:8種聚山梨酯80樣品具有不同程度的直接刺激RBL-2H3細(xì)胞脫顆粒的作用,且呈濃度依賴(lài)性,其中上海試劑采購(gòu)供應(yīng)站提供的受試物作用極強(qiáng),威爾制藥口服級(jí)受試物作用較強(qiáng),威爾制藥A、威爾制藥B、威爾制藥注射級(jí)、威爾制藥4個(gè)受試物作用相近,2個(gè)進(jìn)口品種的作用略弱。在產(chǎn)生直接刺激RBL-2H3細(xì)胞脫顆粒作用的濃度下,上海試劑采購(gòu)供應(yīng)站的聚山梨酯80有明顯的細(xì)胞毒性,并呈濃度依賴(lài)性。結(jié)論:聚山梨酯80能夠直接刺激RBL-2H3細(xì)胞脫顆粒,其作用強(qiáng)度不同反映了產(chǎn)品的質(zhì)量差異;上海試劑采購(gòu)供應(yīng)站提供的聚山梨酯80直接刺激RBL-2H3細(xì)胞脫顆粒的作用可能由其細(xì)胞毒性引起。

[Abstract]
Objective: To study directive effects of multiple kinds of injective excipients on the degranualation in rat mast cell line RBL-2H3 and to provide some indications for establishing a screening and evaluating method for pseudoallergy induced by different Tween 80. Methods: RBL-2H3 cells were cultured and treated with varying dose of Tween 80, and then the amount of releasing β-hexosaminidase was detected. MTT assay was demonstrated to determine the cytotoxicity of injective excipients which causing RBL-2H3 cells degranulation. Results: All of eight different Tween 80 products directly induced RBL-2H3 cells degranulation in a concentration-dependent manner while the degree of this effect was varying (Shanghai > Weier (oral) > Weier (A) = Weier (B) = Weier (injective) = Weier > Nof = Croda). Tween 80 (Shanghai) showed cytotoxicity effect in a concentration-dependent manner. Conclusion: Tween 80 can induce RBL-2H3 cells degranulation directly, and the degree of effect is related to the different quality among these products. Cell degranulation induced by Tween 80 (Shanghai) dues to its cytotoxicity.
