Beneficial effect of chlorpromazine on focal cerebral ischemia by enhancing activity of BKCa channels

Abstract

脑中风因其高发病率、高致残率、高死亡率等特点,成为继心血管疾病和癌症之后的世界第三大死亡原因,严重危害人类的健康。每年世界范围内约有570万人死于急性脑中风,并有不断上升的趋势。虽然脑缺血的病理生理学研究已取得了巨大进步,但目前国内外除溶栓治疗外尚无非常有效的治疗措施。因此寻找发挥神经保护作用的药物具有十分重要的意义。 氯丙嗪是临床上常用的吩噻嗪类抗精神病药物,易于透过血脑屏障,具有多种药理活性,与许多受体和离子通道的关系密切。我们之前的研究发现在全细胞记录模式下,氯丙嗪可激活大电导钙激活钾通道(BKCa通道)。而越来越多的研究发现BKCa通道的激活剂可以保护脑缺血损伤,阻止神经元去极化,减...Stroke is the third leading cause of death because of its high incidence, high mortality and high morbidity. It seriously affects the health of many people. Nowadays approximately 5.7 million people are estimated to die from acute ischemic stroke per year worldwide. Despite advances in the understanding of the pathophysiology of cerebral ischemia in recent years, only thrombolysis, has proven to b...学位:理学硕士院系专业:医学院_微生物学学号:2452010115332
