目的:明确香菇、辣椒、带鱼、羊肉和海虾5种食物对慢性变应性接触性皮炎(CACD)小鼠模型炎症反应及血清 IL-4和 IL-17表达的影响。方法:36只小鼠用2,4-二硝基氟苯诱导建立CACD 模型,5种食物煎煮后灌胃,对照组予纯水灌胃。测量每组耳厚度和耳重量并用 ELISA 检测血清 IL-4和 IL-17水平。结果:与对照组相比,辣椒和羊肉明显增加耳厚度、耳重量和血清 IL-17水平(P〈0.05);带鱼和海虾对小鼠耳厚度和耳重量无明显影响(P〉0.05),但显著下调血清 IL-4水平(P〈0.05);香菇对各项指标均无影响(P〉0.05)。结论:辣椒和羊肉可能通过上调血清 IL-17水平加重CACD 小鼠模型炎症反应。
Objective: To determine the effects of mushroom, chillies, ribbonfish, mutton and sea shrimp on contact dermatitis in mice model. Methods: The contact dermatitis model was constructed by DNFB. The mice were divided into 5 groups and fed with the soup of 5 foods by gavage and the mice in control group were fed with water. Ear thickness and weight were measured. The levels of IL-4 and IL-17 in serum were detected by ELISA. Results: Compared with control group, the ear thickness and weight, and the levels of IL-17 were increased in the chillies group and mutton group(P〈0.05). There was no changes in ear thickness and weight in ribbonfish and sea shrimp group, but the level of IL-4 decreased(P〈 0.05). There were no significant differences in the ear thickness and ear weight changes, and the serum levels of IL-4 and IL-17 between mushroom group and control group (P〉0.05). Conclusion: Chillies and mutton may aggravate the inflamma-tory reaction in contact dermatitis by upregulating IL-17 expression.
