Abstract:OBJECTIVE: This research was designed to ascertain the effect and mechanism of vinpocetine (VIN) and coenzyme Q10 (CoQ10) combination on cognitive impairment induced by电离辐射(ir)。
方法: 小鼠的认知障碍是由9-GY IR诱导的,并且它们在腹膜内注射了VIN,COQ10,COQ10,或VIN+COQ10。然后,使用新颖的物体识别和莫里斯水迷宫测试来检测COGNISTER功能。 NISSL和免疫荧光染色观察到海马神经元和Brdudcxcells的数量。评估了线粒体呼吸复合物I,三磷酸腺苷(ATP)和线粒体膜电位(MMP)以及氧化应激损伤。 Mitophagy in hippocampal neurons was evaluated by observing the ultrastructure of hippocampal neurons and assessing the expression of mitophagy-related proteins.
RESULTS: IR reduced novel object discrimination index, the time for platform crossing, and the time spent in platform quadrant,除神经元丧失外,线粒体呼吸复合物I,ATP和MMP的下调水平加重了氧化应激损伤,LC3 II/I,Beclin1,Pink1和Parkin的表达增加,p62表达降低。 VIN或COQ10治疗可缓解认知功能障碍,神经元丧失,线粒体损伤和氧化应激损伤,并增强M海马神经元中的ITOPHAP。 VIN and CoQ10 combination further protected against IR-induced cognitive dysfunction than VIN or CoQ10 alone.
CONCLUSION: VIN combined with CoQ10 improved neuron damage, promoted mitophagy, and ameliorated cognitive impairment in IR小鼠。
