本研究用立体定位技术与电生理细胞外微电极记录方法，以丘脑后核群（P．O．）胖』总神经诱发单位放电做为躯体痛指标，观察辽宁产东亚钳蝎毒提取物对躯体痛的影响。实验用Wistar大白鼠16只，月龄3～4个月，体重270－350克，雌雄均有，用20％氨基甲酸乙酯腹腔麻醉，5ml／kg，分
In this study, stereotactic techniques and electrophysiological extracellular microelectrode recording methods were used to evaluate the unit discharges of the total nerves induced by the post-thalamic nucleus (P.O.) fat total nerve. Physical pain effects. Sixteen Wistar rats were used in the experiment and they were 3 to 4 months old, weighing 270-350 g, both male and female. They were anesthetized with 20% ethyl carbamate intraperitoneally and 5 ml/kg.
