摘要: 目的: 探讨特异性p38蛋白激酶(P38MAPK)抑制剂SB203580对哮喘小鼠气道炎症和Thl/Th2类细胞因子(IFN-y/IL-4)变化的影响。方法: BALB/c小鼠30只随机分成3组:正常对照组、哮喘模型组和SB203580干预组。采用酶联免疫吸附法(ELISA)检测支气管肺泡灌洗液(BALF)中IL4和IFN-7含量,并观察BALF中炎症细胞和肺组织病理学改变。结果: 与正常对照组比较,哮喘模型组小鼠BALF中炎症细胞计数和IL-4水平升高而IFN-7水平降低(F < 0.01);与哮喘模型组比较,SB203580干预组小鼠BALF中炎症细胞计数和IL-4水平明显降低,IFN-7水平明显上升(P < 0.01),肺组织病理学改变显著减轻。结论: SB203580能抑制哮喘小鼠的气道炎症反应,纠正IFN-y/IL-4平衡的失调。

Abstract: AIM: To investigate the effects of SB203580, a special inhibitor of p38 mitogen-activated protein kinase (p38 MAPK), on the airway inflammation and Thl/Th2 cytokines, IFN-y/IL-4 in mice with asth-matic. METHODS: Thirty mice were randomly divided into 3 groups: normal control group, asthmatic group and SB203580 group. The concentrations of IFN-7 and IL-4 in bronchial alveolar lavage fluid (BALF) were measured by ELISA, The number of inflammatory cells in BALF and the changes of histropathology were observed. RE-SULTS: In asthmatic group, the number of inflammatory cells and the concentration of IL-4 in BALF were higher and the concentration of in BALF IFN-ywas lower than those in normal control group(P < 0.01). In SB203580 group, the number of inflammatoiy cells and the concen-tration of IL-4 in BALF were lower and the concentration of in BALF IFN-ywas higher than those in asthmatic group (P < 0.01). Meanwhile, the histropathology damage was alleviated in SB2035 80 group. CONCLUSION: SB203580 can decrease the aggregation of airway inflam-matory cells and correct the imbalance of IFN-y/IL-4.
