晕车者还能开车吗

一位读者来信说:我今年35岁,前几天,单位实施优化组合,我“出局”了。因人长得高大魁梧,亲友们都说我有一副“好身板”,应去学开车。我经过反复权衡,认为这的确是份“美差”。可我乘车船有时头晕、呕吐,医生说我患有晕动病,不适宜开车。请问,晕动病患者还能开车吗?应如何治疗?     

晕动病、失眠的选择用药

晕动病 一、什么是晕动病 有些人在乘坐汽车、火车、轮船、飞机时,会出现头晕、出冷汗、面色苍白、恶心、呕吐等症状,这些症状在旅行结束后不久就可减轻或消失,称之为晕动病,又称运动病,也就是老百姓所说的晕车、晕船。 二、晕动病的病因 晕动病发生的原因是由于内耳迷路不适应强烈机械震动所致。

模拟晕船大鼠晕船行为学指标的筛选及适应规律的观察

目的:筛选大鼠晕船行为学指标,探讨大鼠晕船适应时间及规律.方法:运用Crampton旋转刺激模型,对SD大鼠进行重复刺激,实时观察晕船刺激过程中尿液、粪便排泄量及刺激后自发活动的变化;采用抗晕药物干预法检验各行为学指标的特异性.结果:与正常对照组相比,晕船刺激第1天刺激组大鼠粪便量显著增加(P<0.05),自发活动显著减少(P<0.01);随着刺激天数的增加,刺激组粪便量、自发活动均逐渐恢复,且与刺激天数间存在一定相关性(P<0.01),并分别于第9天和第7天下降至正常对照水平;用药组以东莨菪碱(0.5、1 mg/kg)灌胃后再进行旋转刺激,各行为学指标与正常对照组相比均无统计学差异.结论:旋转刺激时的排便量和刺激后的自发活动量可有效判断大鼠晕动病,连续刺激9 d左右后大鼠可达到晕船适应.     

环境高温对晕动病发病机制的影响

目的探讨常温与高温环境下晕动病生病的差异。方法261名18～20岁男性军校学员作为受试对象。经体检和“军人体能标准”测试均合格者,分别在20℃常温与38℃高温环境下以科里奥利（Coriolis）转椅诱发晕动病,以格瑞比尔（Graybiel）法评定晕动病程度。结果常温和高温环境下受试者格瑞比尔评分分别为6．53&#177;7．36和7．55&#177;6．75（z=2756．5,P=0．0025）,常温和高温环境下受试者格瑞比尔等级人数,从无症状（N）到极度重症（IV）分别为。46人、37人、47人、62人、39人、30人和47人、37人、30人、32人、51人、64人（z=2410．50,P=0．000．7）。结论高温与常温环境相比．更容易发生晕动病。而且晕动病等级更高。     

飞行人员空晕病的诊治和医学鉴定

Objective To summarize the clinical features,diagnosis and treatment methods,prevention and control measures,and medical evaluation principles for airsickness in flying personnel. Methods Forty-nine cases of flying personnel with airsickness,who were hospitalized from September of 1976 to July of 2009,were retrospectively analyzed in respect of disease course,etiology or incentive,clinical diagnosis and medical evaluation of airsickness.The relationship between vestibular function status and medical evaluation was also statistically analyzed. Results ① Three of 49 picked cases were diagnosed as primary airsickness while the rest 46 were the secondary that were induced by different causes or incentives.Etiological treatment and vestibular habituation were the primarily treatments for such airsickness.② Among these cases,22 were normal in vestibular nystagmus electroretinogram (VNG) comparing to 27 abnormal cases.③ Sixteen and 33 cases were evaluated as normal and deficient Coriolis acceleration tolerance respectively.④ Eleven flying personnel Were finally qualified while 10 and 28 were temporarily and permanently grounded respectively.Flying personnel with abnormal VNG or with deficient Coriolis acceleration tolerance showed higher grounding rate than those with the normal (χ2=5.584,16.722,P<0.05). Conclusions Airsickness in active service flying personnel is mostly the secondary affection,which is caused by various primary disease or incentives.Such prevention and control measures as treating primary disease.eliminating incentives and implementing vestibular habituation are suggested.The effect of airsickness treatment and vestibular function should be emphasized in making medical evaluation.     

田氏晕宁膏治疗晕动病92例临床观察

晕动病是一种常见病、多发病,是颠簸性运动时,由于过多的、反复的加速度或角加速度刺激内耳前庭系统的毛细胞后,引起副交感神经尤其是迷走神经兴奋所致的一种发作性疾病。长期以来,给人们的工作和生活带来了极大的不便。目前,控制晕动病发作的常用方法是乘车前口服抗组胺药茶苯海明即乘晕宁片。这种方法虽然人人皆知,但仅能缓解部分症状,且具有头昏、嗜睡、倦怠、乏力等副作用,总体疗效不尽人意。     

前庭刺激激活大鼠内侧前额叶皮质神经元Fos表达

目的:分析对比加伐尼刺激(Galvanic stimulation)与双轴旋转运动分别作用于大鼠前庭器官对内侧前额叶皮质(mPFC)神经元活动的影响。方法:将雄性SD大鼠随机分为4组：电刺激组、对照组、双轴旋转运动组和对照组。电刺激组动物以100～200μA电流强度刺激前庭感受器1 h后休养1 h;双轴旋转组动物以双轴旋转运动刺激2 h。应用包含mPFC的25μm脑冠状切片，以免疫组织化学抗生物素蛋白-生物素复合物(ABC)技术进行Fos蛋白免疫反应并以3,3′-二氨基联苯胺(DAB)显色。最后，对mPFC内标记神经元进行计数和统计分析。结果:动物经两种类型分别刺激后，mPFC均见到大量Fos样免疫阳性反应神经元细胞核；曼-惠特尼U检验统计表明每种刺激条件下，刺激组较对照组动物mPFC内Fos阳性神经元数目都有显著增加(P<0.05)。半定量统计显示两种类型刺激后，接受刺激组和对照组动物mPFC内Fos阳性神经元数目激活的神经元数目分别是1053±240.50 vs 44.25±3.64和509.80±54.40 vs 128.30±7.66。结论:诱发晕动病的双轴旋转刺激和伽伐...
