摘要
癫痫(Epilepsy)是神经系统所见的常见病、多发病之一。罹患本
    病,因其发复发作性、发作突然性、复杂性等特点,故其病程较长,
    治疗不易,给患者的日常工作、学习、生活以及身心健康带来了诸
    多压力,给社会带来了沉重的负担。癫痫发病,在年龄分布上,各
    种年龄均可发病,但在10岁前的发病率最高,给患儿的身体和智
    力正常发育带来了种种影响。临床治疗上,不但要早发现、早治疗,
    而且要控制发作期,延长间歇期,最终达到完全治愈。目前对于癫
    痫发病机理的认识尚不十分清楚,有绝对疗效的治疗手段尚未发
    现,迄今为止仅仅停留在症状治疗的认识上。故要提高治愈率,有
    效控制癫痫发作,开发高效低毒、价廉的抗痫药物,需要进行大量
    浩繁而有实效的研究工作。
     现代医学在近几十年来对癫痫的认识越来越深入,无论是在生
    理、病理、免疫还是遗传学等领域都有较大的进展,近几年逐渐深
    入到分子、基因水平,相关指标的检测和研究不断深化,但对癫痫
    发病机制目前尚未能达到统一的认识。自1969年至今,学者先后
    提出了三种有关癫痫发病机制的不同理论和假说,GABA(γ-氨
    基丁酸)能系统缺陷假说目前研究最深入、最成熟,其中部分观点
    已经为大多数专家和学者所认同。关于神经递质与癫痫发病关系的
    报道相当广泛,在癫痫发病中作用机制的相关研究最早也最深入。
    GABA和GLU(谷氨酸)是大脑中最主要的两类神经递质,两者
    起到相互制约的作用。正常时,两类递质处于动态平衡;病态时,
    两类递质的平衡关系——即GABA—GLU系统遭到破坏,引起癫
    痫发作的概率成倍增加。目前的研究表明,这些递质在癫痫发作的
    发生、扩散及终止中起重要作用。目前常规及大部分新型抗痫药物,
    都是根据这一理论开发研制的,临床运用取得了一定的疗效,但并

Epilepsy is very popular in nervous system diseases. Epileptic
     seizure suddenly and complicatedly make it a long course of disease
     and hard to treating, also bring the patients much pressure on their study,
     living and working. Epilepsy comes on at different ages, but the highest
     occurrence rate happens before the age of 10, and makes many
     disadvantages to the normal growing of body and intelligence of the
     little patient. So finding it out early and treating early is very important
     to the curation of epilepsy. The cause of epilepsy is not very clear till
     now, and there is not a treating measure with absolute curative effect.
     So it is a very hard working before an exactly treating measure is
     found.
    
     The knowledge about epilepsy is more and more deeply in modern
     medicine , and has achieved much progress on the aspect of
     physiology,pathology,immunology et al, and gone deep into molecule
     level or gene level. Though the cause of Epilepsy hasn't been totally
     certained, since 1969 the scholars have posed three different hypothesis
     about it: 1) hypothesis of destroying nerve colloid; 2) hypothesis of
     losting energy-oxygen of GABA; 3) hypothesis in balance of GABA
     system. The two later are considered as the deepest and mature ones.
     On the other hand, neurotransmitter is also very related with Epilepsy
     and is the earliest research. GABA and GLU are the most mainly two
     types of neurotransmitter, which are under a dynamic equilibrium in the
     normal state, while the equilibrium is destroyed in the morbid state, and
     the occurancy rate of Epilepsy will increase as much as times.
     Anti-epilepsy medicine are based on this theory, but still cannot totally
    
    
    
    
    
    control all the kinds of Epileptic seizure, and have many serious
     side-effects such as: the inducement of mutagenicity,distortion et al.
    
     Epilepsy is the same name in TCM, and the cause of it in TCM
     theory includes three aspects such as: emotion, congenital factor,
     traumatas of head, et al. The pathology is the results of wind, heat,
     phlegm, hypofunction in body, blood stasis, and the treating method
     mainly includes Calming the wind, Dissipating the heat, Eliminating
     the phlegm, Activating the blood.
    
     Clinical rearch: 81 symptoms with 54 congenital diagnosis and
     feeling of pulse from 500 cases have been analysisted during the past of
     more than 20 years. The result we inferred is that Epilepsy is a
     symptom complex-deficiency of Qi as BEN (the primary) and wind
     involving phlegm with blood stasis as BIAO (the secondary). The
     pathology basis is SHAOYANG unregulated and Q1 in both
     spleen and stomach unstrengthened, disable action, which is the key of
     it. Curations of more than 2000 cases were observed and we found that
     epilepticus seizures repeatedly or alternated with intermittence is the
     remarkable characteristic of Epilepsy. Treating, both based on
     Tonifying QI and coordinated with Calming the wind, Eliminating the
     phlegm, Activating the blood, can achieve significantly curative effect.
    
     Animal experiment: The principle of Tonifying QI with Calming
     the wind and Eliminating the phlegm treating Epilepsy had been known
     in the animal experiment. The result is : Astragali seu Hedysari in group
     of Tonifying Qi can act on GABA, GABA-CPT, GABA-receptor in
     neuron synaptic in the brain and enhance the density of GABA in the
     synaptic ; improving the inhibition of impulse excitability in nerve
     synaptic induced by GABA. Arisaema cum Bile in group of Calming
