中脑导水管周围中央灰质(PAG)、海马背侧与腹侧三者的镇痛效应关系报道较少,背海马镇痛后效应对PAG的影响以及损毁PAG对背海马镇痛作用的影响未见报道。本实验对此进行了观察,探讨PAG在海马镇痛效应中所起的作用。材料与方法实验选用200～300克的健康大鼠共34只,雌雄不拘。麻醉和消毒后,借脑定位仪按JB—ures的大鼠脑图谱定位,将直径0.17mm的同心圆刺激电极插入一侧PAG(P6.5、RLO、H7.0),海马背侧(P3.0、L1.8、H3.2),
There were few reports on the analgesic effects of the central gray matter (PAG), the dorsal and ventral hippocampus, and the effect of the analgesic effect of the dorsal hippocampus on the PAG and the analgesic effect of the damaged PAG on the dorsal hippocampus See report. This experiment was observed, to explore the role of PAG in the role of the analgesic effect in the hippocampus. Materials and Methods The experiment used a total of 34 healthy rats of 200 ~ 300 grams, both male and female. After anesthesia and disinfection, a 0.17 mm diameter concentric exciter electrode was inserted into the PAG (P6.5, RLO, H7.0), the dorsal surface of the hippocampus (P3) by the brain locator according to the JB- .0, L1.8, H3.2),
