    • 摘要: 衰老和睡眠中断人类衰老过程中睡眠质量的恶化是最普遍的抱怨之一。Li等人在一种动物模型中发现,衰老与睡眠期间促进唤醒的大脑区域的自发活动增强相关(参见Jacobson和Hoyer的观点)。表达下丘脑分泌素的神经元在睡眠期间更加活跃,增加了短暂觉醒的机会,从而导致睡眠更加碎片化。老年脑组织中下丘脑分泌素神经元的兴奋性增强,可能是因为钾通道亚群的表达减少。因此,与衰老相关的睡眠碎片化可能是由于促进觉醒的神经元的内在兴奋性改变所致。

    • 摘要: 弗洛姆关注人的自由本质,从心理学和社会学层面,构建出独特的自由思想.自由是人存在的特征.从个人角度出发,自由意蕴经历了三次变迁,即始发、困境和归宿,分别对应了个体化的三个阶段,即前个体化、个体化和后个体化.人处在不同的社会历史背景下,追求自由的过程中,会呈现不同的精神困境,并采取权威主义、机械自我等消极逃避机制,而通过诸如爱、创造性劳动等自发活动来追求的自由,能实现积极的自由.

    • 摘要: 目的 探讨天香胶囊对运动病(motion sickness,MS)模型大鼠行为学的影响及其机理.方法 将60只SPF级雄性SD大鼠随机分为6组:空白对照组、模型对照组、阳性对照组、天香胶囊低、中、高剂量组,每组10只,各组大鼠在造模前1 h给药,采用旋转刺激装置持续刺激2 h,诱发大鼠运动病模型,采用自发活动实验观察大鼠行为学变化、ELISA和放免法检测前庭核乙酰胆碱(ACh)含量和血浆促肾上腺皮质激素(ACTH)、β-内啡肽(β-EP)水平.结果 天香胶囊各剂量组均可增加运动病模型大鼠的自发活动总距离和活动时间,减低血浆ACTH[空白对照组(24.48 ±2.28)ng/L,天香低剂量组(30.56 ± 4.26)ng/L]和β-EP[空白对照组(141.27 ±12.11)ng/L,天香低剂量组(164.03 ±23.60)ng/L]含量以及前庭核ACh[空白对照组(58.87 ±6.03)ng/L,天香低剂量组(67.78 ±10.34)ng/L]含量,且显示出一定的剂量依赖关系.结论 天香胶囊可显著改善运动病模型大鼠的自发活动,其机制可能与缓解中枢神经系统兴奋性降低,降低血浆ACTH、β-EP含量以及前庭核ACh含量有关,提示中药复方天香胶囊对运动病有一定防治作用,其高剂量对模型大鼠作用效果显著,为最佳剂量.%Objective To study the effect of Tianxiang capsules on the behavior of rats with motion sickness and its related mechanism.Methods A total of 60 male SD rats were randomly divided into 6 groups:the blank control group,the model group,the scopolamine group(or the positive control group), the Tianxiang low, moderate and high dosage groups, each consisting of 10 rats. Rats in each group were given medication 1 hour before development of the model,and the animals were exposed continuously to rotating stimulation for 2 hours by using a rotational stimulation device,and the motion sickness model was thus developed.Spontaneous activity was used to observe changes in the behavior of rats,the levels of acetylcholine(ACh), adrenocorticotropic hormone(ACTH)and β-endorphin(β-EP)were detected by using ELISA and radioimmunoassay.Results Total distance and duration of spontaneous activity of the rats in the 3 different Tianxiang dosage groups were all increased to various extents,and the levels of ACTH,β-EP and ACh were decreased in vestibular nucleus,and a dose-dependent relationship could clearly be seen.Conclusion The Tianxiang capsule could significantly improve the spontaneous activity of the rats with motion sickness,the intrinsic mechanism might be related to the decrease of excitability of central nervous system,and the reduction of plasma ACTH,β-EP and ACh levels of vestibular nucleus.It was indica-ted that the compound Tianxiang capsule had certain prevention and treatment effects on motion sickness,and high dosage could produce most significant effects on the model rats,and it was obviously the optimal dosage.

    • 摘要: 影响都市空间成功的因素都有哪些?丹麦建筑师和城市规划师扬·格尔早在20世纪60年代就提出过这个问题,当时他首次调查了城市里街道和广场上人们的行为。在其《建筑间的生活》(1971年)一书中,格尔将户外活动分为三类:必要活动、自选活动和社交活动。他的论点是,供人们进行自发活动和临时起意的休闲活动的公共空间越多,人们的社交生活就会越多。

    • 摘要: 目的 探讨不同阿片类受体对盐酸氢考酮引起小鼠高活动性和镇痛过程的影响.方法 采用小鼠自主活动测定和小鼠热板镇痛的实验方法研究μ、δ、κ 3种阿片在盐酸氢考酮引起小鼠高活动性的不同作用.结果 不同剂量的盐酸氢考酮均能够诱发小鼠的自发活动明显增加,且呈显著的量效关系(P<0.05).非选择性阿片受体拮抗剂能够剂量依赖性地降低盐酸氢考酮引起的小鼠自发活动增加(P<0.05).选择性μ受体拮抗剂对盐酸氢考酮引起的小鼠自发活动增加无影响,而选择性δ受体拮抗剂能够剂量依赖性地降低盐酸氢考酮引起的小鼠自发活动增加(P<0.05).选择性κ受体拮抗剂能够增强盐酸氢考酮引起的小鼠自发活动增加.选择性μ受体拮抗剂和选择性δ受体拮抗剂对小鼠无镇痛作用,而选择性κ受体拮抗剂能够拮抗盐酸氢考酮的镇痛作用.结论 盐酸氢考酮引起的小鼠自发活动增加的作用可能通过δ受体介导,而其镇痛作用则可能是通过κ受体介导.

    • 摘要: Objective To investigate the effects of risperidone and its active metabolite, paliperidone (9-hydroxyrisperidone), on hyperactivity and deficient sensorimotor gating induced by MK-801 in rats. Methods Adult male Sprague-Dawley (SD) rats (n=96) were used in this study. The effects of risperidone (0.1 mg/kg) and paliperidone (0.05, 0.10 and 0.20 mg/kg) on MK-801-induced (0.40 mg/kg) hyperactivity were examined in 48 rats with with 8 animals per group.The effects of risperidone(0.5 mg/kg)and paliperidone(0.10,0.50,1.00 mg/kg)on MK-801-induced (0.25 mg/kg) deficit in prepulse inhibition (PPI) were examined in 48 rats with 8~10 animals per group. Results Risperidone (0.10 mg/kg) and paliperidone (0.05 mg/kg) diminished the MK-801-induced hyperactivity (P0.05);而利培酮(0.5 mg/kg)可逆转MK-801对大鼠PPI的破坏作用(P<0.05). 结论 利培酮和帕利哌酮不同程度地逆转了MK-801引起大鼠自发活动增加及感觉门控功能异常,说明帕利哌酮虽为利培酮活性代谢产物,但二者药理学作用不尽相同.
