METHODS: We used immunohistochemical ABC and Western blot method to detect the expression of p38 MAPK in lung tissues and airway epithelial cells in acute lung injury rat model and observed the influence of N acetylcysteine (NAC) on the expression.

• 方法 :采用免疫组织化学ABC法和Western blot技术 ；检测磷酸化的 p38MAPK在大鼠急性肺损伤模型气道和肺组织的表达 ；并同时观察N 乙酰半胱氨酸 (NAC)对其表达的影响 .
