Therefore, To exploit the unique properties and to realize and obtain the full potential of the versatile polysaccharide, attempts are being made to chemically modify them. In the life sciences, agricultural chemicals, medicine, separation inspissation and other fields, phosphorus chemistry has a lot of important applications.

因此，许多研究者逐渐把目光转移到了对壳聚糖的化学修饰方面，希望通过化学修饰赋予其更加良好的物理化学性质以及更好的生物活性，使其应用范围更加广泛。

OBJECTIVE: To observe the growth and propagation of vascular endothelial cells on the surface of intravascular stent material.

目的：观察内皮细胞在经刻蚀并构建仿生的生物活性表面，整合细胞外基质成分的金属钛表面的生长情况。

At 10 weeks, smooth muscle bundles were observed and there were no significant difference between the two groups of the number of neogenesis capillary and positive VEGFR2 expression cells. To understand the release of exogenous growth factors from small intestinal submuscosa in bladder regeneration, the release of vascular endothelial growth factor and basic fibroblast growth factor from SIS in vitro were evaluated by ELISA and MTT method.

尽管文献报道制备的小肠粘膜下层中含有少量细胞生长因子，但尚不明确其在动物体内是否仍具有生物活性，为了解小肠粘膜下层在膀胱组织修复中外源性生长因子VEGF和bFGF释放，我们用ELISA法和MTT法体外测量冻干SIS在PBS孵育液中VEGF和bFGF的含量及对上皮细胞的增殖作用；用猪小肠粘膜下层行大鼠膀胱部分修复。
