目的 探讨高应激状态对机体胃肠道激素分泌的影响 ,及应激状态下胃粘膜的损伤情况。方法 采用放射免疫方法 (RIA)对作战部队高射炮兵应急作战射弹演练前后血清中胃泌素、胰岛素水平作了测定 ,并对其胃粘膜变化做了电子内镜检察与分析。结果 血清胃泌素含量射弹后低于射弹前 ,但无显著性差异 (P >0 .0 5 ) ,血清胰岛素含量射弹后低于射弹前 ,有显著性差异 (P <0 .0 1) ;作战官兵的胃粘膜在射弹后有一定程度的损伤。结论 应急作战官兵在应激作战射弹后血清胃泌素和胰岛素水平降低 ,高应激状态能引起胃粘膜损伤。
Objective To investigate the effects of high stress on the secretion of gastrointestinal tract hormones and the damage of gastric mucosa under stress. Methods Radioimmunoassay (RIA) was used to measure serum levels of gastrin and insulin before and after the anti-aircraft artillery fire fighting exercises in combat units. Electron microscopic examination and analysis were performed on the gastric mucosal changes. Results Serum gastrin content of projectile was lower than that of projectile, but there was no significant difference (P> 0.05). Serum insulin content of projectile was lower than that before projectile (P <0.05). 0 1). The gastric mucosa of combat officers and soldiers has a certain degree of damage after the projectile. Conclusion The levels of serum gastrin and insulin in the contingent of officers and men in emergency operations are lower after stress projectile, and high-stress state can cause gastric mucosal injury.
