七氟醚对小鼠海马区BDNF-TrkB-CREB 信号通路表达影响及其氧化应激机制研究 附视频
Zhongguo shiyan zhenduanxue目的 从动物实验角度分析七氟醚对小鼠海马区BDNF-TrkB-CREB信号通路表达影响，并探讨其氧化应激机制。方法 以32只6～7周龄SPF级健康雄性C57BL/6小鼠为研究对象，遵循随机化原则及等额原则分为对照组/实验组，每组16只。对照组予生理盐水，腹腔注射，连续注射5 d;采用颈椎脱臼法将小鼠处死。实验组行七氟醚吸入诱导，七氟醚挥发罐开至8%,氧流量6 L/min,监测七氟醚的呼出浓度；待小鼠麻醉成功后采用颈椎脱臼法将小鼠处死。取固定后的小鼠海马组织，依次放入梯度酒精溶液逐步脱去组织水分 ...
