Summary

在这里, 我们提出了一个方案, 以执行颅内药理实验, 其次是在啮齿类动物的疼痛行为检测。该协议允许研究人员在大脑中提供分子和细胞靶标, 用于治疗疼痛的药理剂。

Transcript

这项技术的主要优点是,它可以用来进一步探索大脑中的疼痛机制和药物作用。为了研究颅内注射对大鼠急性疼痛行为的影响,手术一周后,将大鼠放在哈格里夫斯仪器的玻璃板上,并使用该仪器将红外光束聚焦在大鼠脚的植物区域下的玻璃平面上。要研究两种不同研究药物之间的协同药理作用,请使用一块PE-50管连接到一个10微升汉密尔顿注射器,该注射器配有一个33量量的注射器管,该管比植入导轨外延伸一毫米。

在100秒内将0.5微升或更少的研究药物注射到一个颅内管中。喷油器管在喷射后再放置 60 秒,以方便溶液缓慢扩散。然后,在内注射感兴趣的第二种药物。

注射后20至30分钟,进行植物反射测试五次,如证明。在这个具有代表性的实验中,AMPAkine的颅内分娩显示出一种附加镇痛作用,当与内向内注射吗啡共同管理时,表明颅内注射至少部分地具有在疼痛情况下发现药物激活机制的力量。在尝试此过程时,必须记住密切遵循该过程的时间。

按照这个程序,颅内植入物可以与疼痛分析一起使用,以回答有关大脑区域负责给定疼痛表型,药物作用的可能位点,或可能的疼痛药物机制的其他问题。
