摘 要:目的:探讨资木瓜总提物中莽草酸(Shikimic acid,SA)对C48/80(Compound 48/80)刺激大鼠腹腔肥大细胞(Rat peritoneal mast cells,RPMC)脱颗粒的影响及抗炎作用。方法:HPLC法进行资木瓜总提物中莽草酸成分的定性分析;采用甲苯胺蓝(Toluidine blue,TB)、免疫组化及电镜法进行RPMC鉴定;CCK-8法检测各浓度组RPMC细胞的增殖情况;底物法检测β-己糖苷酶的释放率;ELISA法检测细胞上清中组胺的含量。结果:SA在0~90μg/ml时,对RPMC生长无显著影响;与阳性对照组比较,SA能有效抑制β-己糖苷酶的释放和抑制组胺的分泌。结论:SA通过抑制C48/80刺激的RPMC脱颗粒而抑制炎症介质组胺的释放,进而发挥抗炎作用。Objective: To investigate the effect of Chaenomeles speciosa total extract shikimic acid (SA) on the degr.anulation of compound 48/80 (C48/80) stimulated rat peritoneal mast cells and the anti-inflammatory. Methods: Qualitative analysis of shikimic acid in the total extract of Chaenomeles speciosa by high performance liquid phase; RPMC were identified by toluidine blue, immunohis- tochemistry and electron microscopy; CCK-8 method was used to detect the proliferation of RPMC in each concentration group. The release rate of β-hexosidase was determined by substrate method. The content of histamine in supernatant was detected by ELISA. Results: SA had no significant effect on the growth of RPMC at the concentration of 0-90 μg/ml. Compared with the positive control group, SA could effectively inhibit the release of β-hexosidase and inhibit the secretion of histamine. Conclusion: SA inhibits the release of histamine in inflammatory mediators by inhibiting the degranulation of RPMC stimulated by CA8/80, and then exerts anti- inflammatory effects.
