实验选用SD时雄性大鼠100只,50只实验组大鼠肌肉注射马桑内酯(1—1.25mg/kg),隔日一次),50只对照组大鼠肌注等容量的生理盐水。待动物出现前肢阵挛两天后和点燃达标7天后,分别与其相应的对照组间隔处死制备海马脑片。在CA_1区用细胞外记录群集锋电位(PS)的方法,观察滴加肾上腺素能受体激动剂至记录电极处的胞体层对点燃早期和点燃后的大鼠PS的影响。表明结 One hundred male rats were selected for SD, and 50 rats in the experimental group were intramuscularly injected with coriaria lactone (1-1.25 mg/kg) every other day. 50 rats in the control group were intramuscularly injected with equal volume of normal saline. Two days after the forelimbs of the forelimbs and 7 days after the onset of the forelimbs, the animals were sacrificed and prepared for the hippocampal slices. In the CA_1 region, the effect of dropping the adrenergic receptor agonist to the cell layer of the recording electrode on the PS of the early and ignited rat was observed by extracellular recording of a clustered spike (PS).
