But whether the compound composed of them has suppressive effect on absence - like seizures of genetic tremor rats hasnt been reported. Furthermore, the animal models of investigating antiepileptic drugs were mostly induced by chemoconvulant or electrical stimulation. Since genetic factor is more primary in clinical epileptic patients, we used tremor rats fetched in from Japan as experimental animal models. We implanted electrodes in cortical and hippocampus of tremor rats and then recorded the electroencephalograms to observe effects of the traditional Chinese medicinal compound composed of Scolopendra, Bombyx Batryticatus, Uncaria and Arisacma Consanguineum on absence - like seizures in tremor rats.

而且以往多以化学致痫剂或电刺激等方法造模进行抗癫痫药物的研究，但在临床的癫痫患者中遗传因素占有相当大的比例，所以本实验应用了从日本引进的具有遗传性癫痫小发作的震颤大鼠作为实验动物模型，通过在震颤大鼠脑皮质和海马慢性安插电极后进行脑电图的记录，观察以蜈蚣、僵蚕、钩藤、制南星四味药为主的复方中药制剂对震颤大鼠癫痫小发作的抑制作用。

三种遗传距离中都以海沧和金山的最大，海沧和浮宫的最小，表明秋茄种群内的分化是很低的，盐分含量的差别对秋茄的遗传分化没产生影响。

After extensive survey of species of Takakia, we couldn't have found any individuals because of its limited population distribution, so we decided to add some relevant studies of conservation genetics to make up for the shortage of this project, including the analysis of effect of stand age and management regime on genetic diversity on Thuidium cymbifolium in Western China, and genetic structure of the endangered insular plant Neolitsea sericea on the Zhoushan archipelago. Results showed that the population of T.

藻苔类植物多分布于高山雪域地带，且范围极为有限，课题组经多次野外搜寻，未能采集到活体材料，而课题实施时间仅有1年，因此课题组同时积极开展云杉人工林林下大羽藓遗传多样性恢复的动态变化，以及岛屿地理隔离对濒危物种舟山新木姜子种群遗传结构的影响等研究，以弥补项目实施之不足。

The genetic analysis was carried out for 8 characters on 9 energy cane parents and their 20 combination crosses with the NCII mating design. The results showed that the inheritance of stalk biomass, brix weight, available stalk numbers and weight per stalk was subject to both additive gene effect and non-additive genes effect, but mainly controlled by non-additive genes. The inheritance of plant height, stalk diameter and brix was subject to both additive gene effect. The broad sense heritability (HB2) of stalk biomass and brix was over 50%, and those of brix weight were 33.7% at the seedling stage 54.4% at its ratooning stage, respectively , which means that the selection would be done better at the early stage in the sugarcane breeding program.

利用遗传交配设计对能源甘蔗9个亲本组配的20个组合、8个性状进行遗传分析，结果表明：地上部鲜重、锤重、丛有效茎数和丛重的遗传既受基因的加性效应也受基因的非加性效应所控制，但以非加性效应为主；株高、茎径和锤度的遗传主要是受基因的加性效应控制，地上部鲜重和锤度实生苗新植和宿根的H_B~2都在50％以上，而锤重的H_B~2分别为33.7％和54.4％，而且锤重和地上部鲜重母本gca方差都大于父本gca方差，说明能源甘蔗育种中母本选择的重要性。
