1、肤悦康熏洗液对变应性接触性皮炎的药效及机理研究摘要:目的 本实验通过建立豚鼠变应性接触性皮炎模型,观察肤悦康熏洗液对变应性接触性皮炎的治疗作用及探讨其作用机制。方法本实验以2,4-二硝基氯苯(DNCB)诱发建立豚鼠变应性接触性皮炎(ACD)模型,外用肤悦康熏洗液及外用泼尼松作对照,观察分组给药后豚鼠背部皮肤红肿程度及组织病理变化,同时用酶联免疫吸附试验(ELISA法)检测各组豚鼠血清中白介素-2(IL-2)、白介素-6(IL-6)及白介素-10(IL-10)表达水平。结果ACD模型的豚鼠不同程度地出现皮肤红肿结痂,血清中IL-2及IL-10浓度下降,而IL-6则上升,镜下观察未见正常对照组豚鼠
2、皮肤有炎症细胞,DNCB激发后豚鼠皮肤则见不同程度的表皮细胞变性,说明实验造模成功。给药治疗后,与模型对照组比较,各浓度的肤悦康熏洗液对豚鼠变应性接触性皮炎治疗效果有显著性的的差异,主要表现在豚鼠皮肤的红肿程度减弱,不同程度地改善了表皮细胞炎性,上调了模型动物血清中IL-2及IL-10水平,而抑制了上升的IL-6水平。结论肤悦康熏洗液对变应性接触性皮炎有治疗作用,其作用机制可能与抑制IL-6及促进IL-2、IL-10等细胞因子的释放有关。关键词:肤悦康熏洗液;变应性接触性皮炎;药效研究;作用机理注:本论文题目来源于教师的中山市卫生局医学科研立项项目,项目编号为:2013J103Effects
3、and mechanisms of Fuyuekang lotionOn guinea-pig allergic contact dermatitisAbstract: ObjectiveTo observe the Fuyuekang lotion effects and the mechanism of it on guinea-pig allergic contact dermatitis by establishing allergic contact dematits model. Methods The guinea-pig model of ACD induced by 2,4-
4、dinithochor-benzere (DNCB) was established. Guinea-pig were randomly divided into 5 groups-blank group, DNCB model group, low-level and high doses of Fuyuekang lotion and prednisone group. Guinea-pig skin swelling and histopathologies were observed. The serum level of interleakin-2,interleakin-6,int
5、erleakin-10 and expression of IL-2, IL-6, IL-10 were detected by the method of ELISA. Results The ACD guinea-pigs had swelling symptoms in varying degrees. The levels of IL-2 and IL-6 were declined, but the level of IL-10 was rose. Inflammatory cells were not visibled under a microscope in the norma
6、l control group. The ACD guinea-pigs showed epidermal cell degeneration in different degrees. The results showed the guinea-pig model of ACD were succeed. After drug administration, there was difference of the effcets between DNCB model group, low-level and high doses of Fuyuekang lotion and prednis
7、one group. Fuyuekang lotion reduced the swelling degree、improved the inflammatory cells and declined the level of IL-6 in the serum of the ACD guinea-pig, but rose the levels of IL-2 and IL-10. Conclusion Fuyuekang lotion could relieve the inflammation of ACD. The mechanism of its action may be rela
