摘要 目的观察人参皂苷对重度颅脑外伤大鼠模型环氧合酶(cyclooxgenase-2,COX-2)mRNA表达的影响。方法选取健康wistar大鼠56只,分为正常对照组、模型组和人参皂苷组,Feeney法制作重度颅脑外伤模型,人参皂苷组在造模前30min按5mg/kg灌胃人参皂苷。造模后6、24、72h共3个时相点取各组大鼠脑组织,应用RT-PCR法检测各组神经细胞COX-2mRNA的表达。结果正常对照组未见COX-2mRNA的表达;模型组和人参皂苷组脑外伤后6h出现COX-2mRNA的表达,24h达到高峰,72h后明显减少;人参皂苷组各个时间点COX-2mRNA的表达明显低于模型组。结论重度脑外伤存在COX-2mRNA的异常表达,人参皂苷能抑制COX-2mRNA的表达,可能对脑外伤有一定的保护作用。
