研究了大鼠迷走神经背核（DMV）在调节胃功能和影响电针保护胃粘膜损伤中的作用。电损毁DMV组与假手术组和掼毁其他脑组织组（网状巨细胞核）比较，可降低胃粘膜血流量和跨膜电位差，在应激后更加剧（P＜0．01）。损毁DMV后能基本消除电针对胃粘膜损伤的保护作用。结果提示，中枢迷走通路，特别是DMV在调整胃功能和影响电针的保护效应中起重要作用。
The effect of rat vagus nerve dorsal nucleus (DMV) on regulating gastric function and affecting electroacupuncture in protecting gastric mucosal injury was studied. Compared with the sham operation group and the other brain tissue (DMG), the damage of DMV group could decrease the gastric mucosal blood flow and the transmembrane potential difference and intensify after the stress (P <0.01). Destruction of DMV can basically eliminate the protective effect of electroacupuncture on gastric mucosal injury. The results suggest that central vagal pathways, particularly DMV, play an important role in regulating gastric function and affecting the protective effects of electroacupuncture.
