Results After used the SGS , the arrange of collagen tend to unifying , micrangiums are rich and in opening condition, the polymeride of pre-collagen accumulate in cytochylema in fibroblast, the total content of collagen is decreased, but the content of hPcⅢ is kept in a high level, the content of HA is increased gradually,which closes to the normal skin level.

结果 应用硅凝胶膜后，胶原排列趋于一致，微血管丰富而呈开放状态，成纤维细胞的前胶原聚合体蓄积在细胞浆内；胶原总的含量减少，但Ⅲ型前胶原含量维持在一个较高水平；透明质酸含量逐渐升高，接近正常皮肤水平。

This study was based on the soy protein isolates as raw materials. Chemical modification( acetylation,succinylation ,phosphorylation and urea modification) of SPI were used to improve adhesive strength and water resistance of SPI-based plywood adhesives. Then two modified ways combined were applied to SPI and their adhesive properties were studied. This research also characterized the thermal and adhesive properties of two major soy protein components 7S conglycinin and 11S glycinin after urea modification. Finally, the mechanism of improving SPI's adhesive properties was preliminarily discussed.

Results: ApoD was observed positively expressed in type2 astrocytes and oligodendrocytes from O2A lineage, while it was not expressed in type1 astrocytes from T1A lineage. Accordingly, we can verify the phenomenon found in the study of T1A and T2A gene different expression profile that ApoD mRNA was highly expressed in T2A and lowly expressed in T1A. Conclusion: It can be concluded that lipid metabolism related genes such as ApoD play important roles in the generation and differentiation of O2A lineage, which closely correlate with internal mechanism of lipid metabolism in the brain and myelogenesis.［Key words］astrocyte(T1A, T2A); oligodendrocyte; O2A lineage; apolipoproteinApoD

我们已采用基因芯片技术在mRNA水平研究两型星形胶质细胞的基因表达谱差异，发现ApoD在2型星形胶质细胞中差异高表达，故本文拟用激光共聚焦双重免疫荧光标记技术进一步在蛋白质水平观察ApoD在体外分化成熟的两型星形胶质细胞以及少突胶质细胞中的表达情况，以期为我们深入研究ApoD等脂代谢相关基因在脑内脂质代谢和神经髓鞘发育机制中所起的作用提供有用的实验依据，依此探讨胶质细胞发生和分化的信号机制。

Metal/ oxide composite aerogels can be used as catalysts because of their high specific surface area. In this paper, Co-rich Co/SiO2 composite aerogels in which mass fraction of Co can reach 66%were firstly prepared by sol - gel process of Co-containing tetraethyl orthosilicate. The influence of H2O, catalyst, solvent and composition of Co-containing tetraethyl orthosilicate on the sol-gel process are discussed.
