Recent evidence suggests that the blockade of cannabinoid CB1受体可能有利于缓解帕金森病的典型运动抑制。在这里,我们调查了CB的拮抗作用1受体会改善Premotor Parkinson疾病的大鼠模型中的情感和认知缺陷。利用强制游泳试验和社会识别试验评估了抑郁的行为和认知。确认我们以前的研究,在纹状体中注射6-羟基多胺的大鼠呈现了通过急性注射SR141716A改善的情绪和认知改变。单胺水平的HPLC分析显示SR141716A注射后纹状体和前额叶皮质的改变。这些发现表明CB的作用1早期症状中的受体因纹章中的多巴胺能神经元变性而引起的,如帕金森病的疾病所观察到。SN - 2090-8083 UR - https://doi.org/10.4061 / 2010/238491 Do - 10.4061 / 2010/238491 jf - 帕金森病Pb - 鼠尾草疾病访问研究kw - er -
