| 摘 要： | 目的：探讨躯体性及心理性应激状态下大鼠胃粘膜ＮＯＳ活性变化及其与胃粘膜损伤的关系。方法：将９６只雄性ＳＤ大鼠随机分为３组：对照组,规则光（Ｒ）组及不规则光（Ⅰ）组,采用高压恒流脉冲刺激器制备躯体性和心理性应激模型。分光光度法检测胃粘膜组织的ＮＯＳ活性和Ｎｉｌｓ Ｌａｍｂｅｃｈｔ法测定胃粘膜损伤指数。结果：正常情况下ＮＯＳ活性平稳,应激氏大鼠胃粘膜ＮＯＳ活笥均明显升高,Ⅰ组升高程度更明显;与对照组比

| Abstract: | Objective: To explore the relation between the activity changes of nitric oxide synthase and acute gastric mucosal lesion in gastric mucosa under physical and psychological stress. Methods: Animal model was constructed with impulsive stimulator of high voltage and stable currency. Ninety six male SD rats were randomly divided into 3 groups: control, regular and irregular group. NOS activity was measured by spectrophotometry and injure of gastric mucosa was measured by method of Nils Lambecht. Results: NOS activity was stable in normal rats but increased significantly in group of psychological stress( P <0.05); gastric mucosa injury were observed in regular group, irregular group and the later was server( P < 0.05). Conclusion: The degree of increase of the NOS activity and gastric mucosa injury are positively correlated to the severity of psychological stress. |
