目的:观察针灸对海洛因复吸大鼠条件性位置偏爱的行为学改变及脑神经元超微结构变化的影响,探讨针灸的作用机制。方法:Wistar大鼠32只随机分为正常组、模型组、药物组和针灸组,每组8只。递增量肌肉注射海洛因,按染毒(成瘾)→脱毒的方法,反复3个阶段,建立海洛因复吸大鼠模型。药物组在染毒期给予大鼠连续递增量肌肉注射海洛因,在脱毒期给予美沙酮灌胃治疗;针灸组在染毒期处理与药物组相同,在脱毒期给予针灸治疗(针刺"百会"穴,艾灸"肾俞"穴)。记录造模前、后及治疗后各组大鼠在暗箱内的停留时间,于实验第39天取材并运用透射电镜观察脑前额叶皮质(PFC)神经元超微结构。结果:造模后与造模前相比,模型组、药物组、针灸组大鼠在暗箱停留时间明显缩短(P<0.01);治疗后与模型组、药物组相比,针灸组大鼠在暗箱停留时间明显延长(P<0.01)。与正常组相比,模型组、药物组大鼠脑PFC在电镜视野下可见不同程度的胞质空泡、水肿,粗面内质网扩张,线粒体空泡、消失,核糖体数目减少,核膜间隙增宽;与模型组和药物组相比,针灸组大鼠脑PFC线粒体、核糖体数目略有增多,线粒体嵴比较清楚,粗面内质网数量相对增多,但有轻度扩张,核膜间隙正常。结论:针灸可干预海洛因复吸大鼠条件性位置偏爱的行为学改变,对海洛因复吸大鼠脑组织的损伤具有一定的保护作用。

中风,乃中医病名,可分为内风与外风,前者为内伤病症,俗称脑卒中;后者为《伤寒论》所载的受风邪所致。现在医学上所讲多为前者,中风一旦发生,目前仍无理想医疗方法,患者轻则瘫痪,重则丧生,因此预防中风是非常重要的。中风病常见于中老年... 详细信息

中风,乃中医病名,可分为内风与外风,前者为内伤病症,俗称脑卒中;后者为《伤寒论》所载的受风邪所致。现在医学上所讲多为前者,中风一旦发生,目前仍无理想医疗方法,患者轻则瘫痪,重则丧生,因此预防中风是非常重要的。中风病常见于中老年人,大多数是由于气血逆乱、血溢或者脑脉痹阻等造成,导致患者出现口舌歪斜、言语不利、半身不遂等。此病来势凶猛,并发症和后遗症多且严重,预后效果差,为病患和家庭带来严重的负担。
