摘要
目的 :观察大鼠油酸型急性呼吸窘迫综合征 (ARDS)不同时间血清及肺组织中白细胞介素 - 6(IL -6)、IL - 8和肿瘤坏死因子 (TNF -α)的水平变化以及山莨菪碱 (654 - 2 )对其影响。方法 :经舌下静脉注射油酸复制大鼠ARDS模型 ,用酶联免疫吸附试验测定不同时间血清及肺组织匀浆上清液中IL - 6、IL - 8和TNF -α水平。结果 :注射油酸 4h组血清及肺组织中IL - 6、IL - 8和TNF -α水平明显高于对照组 ;注射油酸 8h组上述细胞因子均明显低于 4h组 ,但血清中IL - 6、TNF -α和肺组织中IL - 6仍高于对照组水平 ;注射油酸 1 6h组血清IL - 6、TNF -α水平明显低于 8h组 ,但TNF -α水平仍高于对照组 ,肺组织中IL - 6水平亦高于对照组。 654 - 2干预组血清及肺组织中IL - 6、TNF -α水平均明显低于未干预组。结论 :IL - 6、IL - 8和TNF -α在大鼠油酸型ARDS炎症过程中可能起重要作用 ;654 - 2可能通过抑制IL - 6、TNF -α过量分泌 ,减轻肺损伤 。
AIM: To observe the changes of interleukin-6(IL-6), IL-8 and tumor necrosis factor-α(TNF-α) in serum and lung at different time, and the effects of anisodamine (654-2) treatment in rats with oleic acid-induced ARDS. METHODS: The ARDS model induced by intravenous injection of oleic acid in the rat was used and levels of IL-6, IL-8, TNF-α in serum and lung tissue supernatant were measured using enzyme linked immunosorbent assay (ELISA). RESULTS: Levels of serum and lung tissue IL-6, IL-8, TNF-α in oleic acid type ARDS 4 h group were increased significantly. These cytokines in oleic acid type ARDS 8 h group were lower than that of ARDS 4 h group, but serum IL-6, TNF-α and lung tissue IL-6 were still higher than that of control group . In oleic acid type ARDS 16 h group, serum IL-6, TNF-α were lower than that of the ARDS 8 h group and serum TNF-α and lung tissue IL-6 were higher than that of control group. After 654-2 treatment, the levels of serum and lung tissue IL-6, TNF-α were decreased significantly. CONCLUSION: IL-6, IL-8 and TNF-α might play important roles in the oleic acid-induced ARDS in the rat. 654-2 might alleviate ARDS by inhibiting excess production of IL-6 and TNF-α.
