注射用双黄连类过敏反应与特异性免疫细胞之间关系的探讨

目的:将ICR小鼠、SCID小鼠和BALB/C裸鼠用于注射用双黄连(SHLI)类过敏反应研究,以探讨SHLI类过敏反应的发生与特异性免疫细胞之间的关系。方法:ICR小鼠、SCID小鼠和BALB/C裸鼠耳廓血管通透性分析:小鼠随机分成不同实验组,不同组的小鼠分别一次性静脉注射含有0.4%伊文思蓝的不同浓度的Compound 48/80溶液、注射用双黄连(SHLI)、生理盐水,给药后30 min记录各组动物耳廓血管通透性增高反应的阳性率,进行耳廓蓝染程度评分,并定量测定耳廓伊文思蓝渗出量。结果:SHLI 300,600 mg.kg-1(分别相当于临床剂量的等效剂量和2倍剂量)静脉注射均可引起ICR小鼠耳廓血管通透性增高,耳廓明显蓝染。以上剂量的SHLI均未引起SCID小鼠和BALB/C裸鼠小鼠耳廓蓝染。结论:SHLI在临床等效剂量和2倍临床剂量下有明显增高血管通透性的作用,提示有致ICR小鼠类过敏作用;相同剂量的SHLI对于免疫缺陷小鼠没有致类过敏作用,提示特异性免疫细胞可能参与了SHLI的致类过敏反应。

Relationship between specific immunocyte and pseudoanaphylactoid reactions induced by Shuanghuanglian injection

Objective: To investigate the relationship between specific immunocyte and pseudoanaphylactoid reactions (PR) induced by Shuanghuanglian injection (SHLI). Method: ICR mice, SCID mice and BALB/C athymic mouse were divided into different test groups, the mice were intravenously injected with solutions of different concentration of SHLI, positive control Compound 48/80 and normal sodium. All test substances were mixed with 0.4% Evans blue. The reaction and vascular permeability of the ears were observed and measured 30 min after SHLI injected. Result: SHLI of 300, 600 mg·kg^-1 caused obvious vascular hyperpermeability in ICR mice, but the same dose of SHLI didn't cause vascular hyperpermeability in SCID mice and BALB/C athymic mouse. Conclusion: SHLI in equivalent and 2 times the clinical dose can cause PR in ICR mice, but the same dose of SHLI can't cause PR in SCID mice and BALB/C athymic mouse, so specific immunocyte maybe take part in the SHLI-induced PR.
