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 ...

Zhongshan Daxue xuebao. Yixue kexue ban, 1995 为了解在肝硬变的发展过程中脾脏的形态结构和功能将出现何种变化。本实验动态观察了以四氯化碳诱发大鼠肝硬变病程中不同时期，脾脏的形态结构及抗感染功能的变化。结果发现，在肝硬变发展的各个阶段，脾脏的形态结构出现了一系列变化，初期脾组织充血、水肿；随之。白髓动脉周围淋巴鞘区及生发中心增生；最后，红髓面积扩大，白髓面积缩小，纤维组织增生，同时伴有脾脏的抗感染功能明显下降。研究提示，在肝硬变形成以后，脾脏也逐渐出现纤维化改变，而失去原有的功能。
