摘要
目的观察重复经颅磁刺激(rTMS)对大鼠海马、齿状回星形胶质细胞和小胶质细胞标记物胶质纤维酸性蛋白(GFAP)、Ⅲ型补体受体(OX42)表达的影响。方法每日1次给予大鼠1Hz、100mT的TMS10min,共14d,观察大鼠行为的变化;14d后采用免疫组化ABC法检测其海马、齿状回GFAP、OX42的表达,并与对照组比较。结果rTMS组、对照组大鼠海马、齿状回GFAP、OX42阳性表达物在形态、数量等方面差异无显著性。结论本实验条件下的rTMS不会造成大鼠中枢神经系统明显损伤。
Objective To observe the effects of repetitive transcranial magnetic stimulation (rTMS) on the expression of glial fibrillary acidic protein (GFAP) and OX-42 in hippocampus and dentate gyrus in rats.Methods The rats were treated with 1 Hz, 100 mT TMS 10 min once a day for 14 days, and then the expression of GFAP and OX-42 in hippocampus and dentate gyrus were investigated by ABC technique of immunohistochemistry.Results Compared with the control group, there were no significant difference in the expression of GFAP and OX-42 between the two groups.Conclusion rTMS using our parameters does not cause brain injury in rats.
