Gliosis plays a critical role in post-traumatic epileptogenesis. The inhibition of the proliferation of astrocytes with 7β OHCH could influence synaptic plasticity, modulate the imbalance of excitatory and inhibitory systems in hippocampus and postpone the latency between injury and the occurrence of chronic spontaneous seizures, furthermore to some extent, reduce the occurrence of post-traumatic epilepsy.

星形胶质细胞增生在创伤性癫痫发病机制中起重要作用，抑制胶质细胞增生，可影响海马突触可塑性，有利于调整海马内兴奋性和抑制性功能系统之间作用的失衡，可延长损伤与发生慢性自发性抽搐之间的间歇期，在一定程度上降低创伤性癫痫的发病率。

Uses: Control of a wide range of insects (particularly Lepidoptera, Hemiptera, Homoptera, Diptera and Coleoptera) and spider mites in fruit, vines, olives, hops, vegetables, ornamentals, field crops, cucurbits, flax, cotton, tobacco, soya beans, etc. Also used for control of flies in animal and poultry houses and dairies.

具有触 杀和胃毒双重作用，进入虫体后，抑制乙酰胆碱酯酶，使昆虫神经传导中起重要作用的乙酰胆碱无法分解造成神经冲动无法控制传递，使昆虫出现惊撅、过度兴奋、麻痹与震颤而无法在作物上取食，导致最终死亡。

Effective antibiotic cure can promote the recovering of the rhinal film function.

慢性鼻窦炎是多种因素作用的结果，其中细菌感染在其发病中起重要作用，有效的抗生素治疗可以促进粘膜纤毛清除功能的恢复。

The infection of bacillus is also an important aspect in this disease. Therefore, effects of sensitive antibiotic should not be neglected to the recovering of the rhinal film function, and to the improvement of the cilia clearance retio.

细菌感染在其发病中亦起重要作用，所以敏感抗生素对于鼻腔粘膜功能的恢复，提高纤毛清除率的作用不容忽视。

Stuber et al.(1992) considered the overdominance is the major genetic basis of heterosis in maize; Xiao et al.(1995) suggested the dominance is the major molecular mechanism of heterosis in rice. Subsequently, Yu et al.(1997) and Hua et al.(2003) demonstrated the epistasis made the siginificant contribution to heterosis in rice.

Stuber等认为，超显性是玉米杂种优势形成的主要原因；Xiao等(1995)认为显性作用是水稻杂种优势形成的遗传基础，Yu等(1997)和Hua等(2003)认为上位性在杂种优势形成过程中起重要作用。

In the present paper, the Sox gene expression analysis of different tissues from the Trionyx sinensis was studied by using RTPCR, and Sox gene fragments of expression from the testicle, brain and spleen were cloned using RTPCR products. The results show that Sox gene has specific expression in the testicle, brain, spleen, cardiac muscle and kindney and hasn't expression in muscle, liver and ovary. The results of clone reveal that the Sox genes of expression in the testicle are TSSox1 and TSSox 4, and those are TSSox2 and TSSox4 in the brain, and that is TSSox4 in the spleen. This suggests that the Sox gene act important role not only on the sex determination, but also on the development of neural system, immunocyte system and the differentiattion of male germ cell.

本文采用RT—PCR技术，研究了中华鳖不同组织Sox基因的表达，并通过PCR直接克隆法，分析了来自睾丸、脑和脾组织中的Sox基因序列结果表明在中华鳖的成体组织中，Sox基因在脑、心肌、肾、脾和雄性的睾丸组织中均有不同程度的表达，而在肌肉、肝脏和雌性的卵巢中则无表达，显示该基因具有组织表达特异性克隆分析显示，在睾丸组织中表达的是TSSox1和TSSox4基因，而在脑组织中表达的是TSSox2和TSSox4基因，脾组织中表达的是TSSox4基因此结果表明Sox基因不仅在性别决定中起作用，还可能在神经系统、免疫系统多种组织中起重要作用

To get more factors associated with erythropoiesis in K562 cells, modified differential display reverse transcription polymerase chain reaction method was applied to identify genes with differential expression in uninduced and hemin-induced K562 cells. Remarkable differential ESTs were firstly selected for cloning, sequencing and analyzed with bioinformatics methods.

为了进一步获得分化过程中相关基因表达的信息，我们应用改良的差异显示RT-PCR技术，分析K562细胞在Hemin诱导的红系分化前后的基因表达变化，获得红系分化相关基因的线索，进而确定在红系分化中起重要作用的基因，并研究它们的作用机制。

It appears to play an important role in both vasculogenesis and angiogenesis.

血管内皮生长因子是血管特异性生长因子，能特异性地作用于血管内皮细胞，诱导血管生成，在血管发生和血管形成过程中起重要作用。

Vascular endothelial growth factor has also been termed vascular-specific growth factor that is specific for the vascular endothelium. It appears to play an important role in both vasculogenesis and angiogenesis.

血管内皮生长因子是血管特异性生长因子，能特异性地作用于血管内皮细胞，诱导血管生成，在血管发生和血管形成过程中起重要作用。

Root border cells are recently defined alive population sloughed from root tips and loosely adhered in the water soluble mucilage, and the root tip is just the target of Al toxicity, thus it was guessed that border cells might function crucially in the response to Al toxicity.

根边缘细胞是从根尖脱落下来并聚集在根尖周围的一群特殊的细胞，在根际周围起着至关重要的作用，国内外研究表明铝毒对植物影响最快的部位是根尖，而根边缘细胞在根尖产生并聚集根尖周围，因此推测根边缘细胞在根对铝毒响应中起重要作用。

Chrysanthemum of 10 thousand birthday is lax to edaphic requirement, with the arenaceous qualitative loam with fecund, good drainage had better.

万寿菊对土壤要求不严，以肥沃。排水良好的砂质壤土为好。

He unstepped the mast and furled the sail and tied it.
