The mechanism of its whitening function was studied at cell level,and we found that there are three approaches by which GN can exert its function:① inhibiting the activity of tyrosinase;② repressing the growth of melanocyte;③ stimulating skin cell to produce lysosome to phagocytose the melanin.

In the suboesophageal ganglion, 5-HT/TPH-like immunoreactive neurons (ca.15) mainly distributed in the lateral and ventro-lateral area, with processes projecting into the suboesophageal ganglion neuropil.

结果表明，5-HT作为经典的神经递质在昆虫的视觉信息处理过程中发挥着重要的调节作用，且主要通过远距离的广域神经调节模式来控制昆虫的昼夜节律行为，并在特定区域和GABA协同起作用；昆虫视觉系统中5-HT的含量还可能与其明暗适应的生理调节方式密切相关。

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

After light radiation time of one hour,the IC50 of cytotoxicity of C60 liposomes is 154.9 μg/ml.During the concentration of C60 liposomes are 16.86 μg/ml and 33.72 μg/ml separately,the plaque reduction rate of direct virucidal activity to HSV-1F strain is positive correlation to the time of light radiation,the correlation coefficients rate 0.8510（P.005） and 0.9766 （P.005） respectively.

光照1 h，C60脂质体对Vero细胞的细胞毒为154.9 μg/ml.C60脂质体浓度为16.86 μg/ml及33.72 μg/ml时，对HSV-1F株直接杀灭的空斑减数率与光照时间成正相关，相关系数r分别为0.8510（P.005）和0.9766（P.005）；当C60脂质体浓度为16.86 μg/ml时，对HSV-1F株感染阻断的空斑减数率与光照时间正相关，相关系数r依次为0.84（P.005）及0.9923（P.005），说明C60的抗病毒作用具有时间效应，主要是光敏动力学机制起作用。

Reversible inactivations of the cerebellar nuclei and inferior olive have implicated the olivo-cortico-nuclear loop in the acquisition of nictitating membrane conditioning, but the role of the cerebellar cortex in acquisition has not been tested directly.

可逆的小脑核和下橄榄体失活暗示橄榄体皮质核环在瞬膜制约的获得中起作用，但是小脑皮质在获得方面具体作用还有待探索。

"SLiMs consist of about three-to-five specific amino acids in the protein and could be responsible for the signaling pathways between many proteins, because they control the ways in which proteins interact," says Richard Edwards with the Bioinformatics and Molecular Evolution Group.

&SliMs 由大约3-5种蛋白质中的特殊氨基酸组成并且能够在众多蛋白质中的信息的转导途径中起作用，因为它们以蛋白质互相作用的途径控制。&生物信息学和分子进化研究小组的Richard Edwards 说。
