摘要
目的:研究咪唑斯汀、氯雷他定及西替利嗪对变应性接触性皮炎(allergiccontactdermatitis,ACD)小鼠产生干扰素(IFN)、肿瘤坏死因子(TNF)及白介素(IL)-4的影响,探讨抗组胺药治疗ACD的作用机制。方法:建立小鼠ACD模型,采用ELISA法检测ACD小鼠产生IFN-γ、TNF-α和IL-4的水平及3种药物分别对它们的作用。结果:ACD小鼠血清及脾淋巴细胞IFN-γ水平均明显升高(P<0.01);血清TNF-α水平明显升高(P<0.01),腹腔巨噬细胞产生TNF-α水平无明显变化(P>0.05);血清及脾淋巴细胞产生IL-4水平无明显变化(P>0.05)。咪唑斯汀对血清及细胞培养液中3种细胞因子的水平均有显著或不同程度的抑制作用,而氯雷他定、西替利嗪仅对部分细胞因子产生一定的抑制作用。结论:咪唑斯汀对ACD小鼠产生的3种细胞因子的抑制作用强于氯雷他定和西替利嗪。它们对ACD小鼠3种细胞因子的抑制作用与临床疗效的关系有待进一步研究。
Objective: To investigate the effects of mizolastine on cytokine expression in murine allergic contact dermatitis(ACD) compared with loratadine and cetirizine, and to study the probable mechanisms of antihistamins to treat ACD. Methods: The animal model of allergic contact dermatitis was established, and the levels of IFN-γ TNF-α and IL-4 were detected by enzyme-linked immunosorbent assay (ELISA) in ACD mice treated with mizolastine, loratadine and cetirizine. Results: The levels of IFN-γin serum and the suspensions of spleen cell-culture as well as the levels of TNF-α in serum of ACD mice were significantly increased (P〈 0.01 ), meanwhile the levels of TNF-α from peritoneal macrophages and IL-4 in serum and the suspensions of spleen cell-culture were not changed (P〉 0.05). The levels of the three cytokines in serum and suspension of cell-culture were all depressed by mizolastine significantly or in different degrees, and the inhibitory effects of loratadine or cetirizine on the cytokines were partial and weaker. Conclusion: The inhibitory effects of mizolastine on the three cytokines of ACD mice are stronger than those of loratadine or cetirizine.
