The results show that this kind of IPN hydrogels are temperature-sensitive, and, compared with inorganically crosslinking PNIPAAm hydrogels, these IPN hydrogels exhibit enhanced storage modulus and ultrafast response rate, such as losing water of 90% within 10 min because of the porous structure which provides the water-releasing channel; by incorporation of PAAm network, the phase transition of PNIPAAm hydrogels is weakened, but the lower critical solution temperature is increased.

研究表明，该IPN凝胶具有温度敏感性；与未互穿的无机交联PNIPAAm凝胶相比，IPN凝胶具有多孔的网络结构和超快的响应速率，如10min内失去90%的水；其储能模量增加了3~4倍，相转变行为变弱，而最低临界溶解温度提高了1.4℃。

We introduced improved primary mixed glial culture and different-attachment method to isolate and purify the OPCs, the cells were proliferated in serum-free medium, flow cytometry and immunohischemistry methods were employed to estimate the purity of cultured OPCs. Their abilities of differentiation and expression of trophic factors were identified by RT-PCR and immunostaining. Several methods including TUNEL and MTT were adopted to estimate the protective effects of conditioned culture medium from oligodendrocyte lineage cells on the primary cultured cerebellar granule neurons. Intravitreal transplant of OPCs, combined with retrograde fluorescent labeling the superior colliculus and intraorbital optic nerve transection, were used to investigate the protective effects of OPCs on the axotomized RGCs in vivo. Intravitreal transplantof OPCs or NSCs on the newborn rats, and retinal transplant of OPCs on the young rats were performed, to observe the myelin formation in the retina at different stages after cellular transplantation. Optic nerve transection was carried out on some rats with myelinated retinae, to study the influence of myelination on the injuried RGCs.

为此，本研究采用改良的胶质细胞混合培养与差速贴壁方法获得大鼠OPCs，使用无血清培养基进行扩增、培养，用免疫组织化学和流式细胞技术对培养细胞的纯度进行鉴定，对少突胶质系细胞表达部分营养因子的情况进行检测；采用TUNEL、MTT等方法对少突胶质系细胞条件培养基对原代培养小脑颗粒神经元的保护作用进行检测；将OPCs移植入成年SD大鼠玻璃体内，利用上丘逆行荧光标记技术，观察眼内移植的OPCs对眶内视神经切断时的视网膜神经节细胞的保护作用及其持续时间；将OPCs或NSCs移植入新生和幼年SD大鼠玻璃体或视网膜内，观察不同时期视网膜内髓鞘形成与分布特点，分析髓鞘的超微结构，并观察眼内髓鞘形成对损伤神经节细胞的保护作用。

The impact of temperature,pH and ionic strength on the volume phase transition of the hydrogels is studied.The result shows that the volume phase transition temperature of ionizable and thermosenstive copolymer hydrogels depend upon the hydrophilic/hydrophobic character of the comonomers...

结果表明，疏水基末端端基的疏水程度决定凝胶体积相变的速率，随着疏水性单体甲基丙烯酸酯烷基链的增长，凝胶的疏水性增强，凝胶的相转变pH向低pH处迁移；温度高于LCST时，分子间的氢键作用减弱，疏水基团间的相互作用加强，凝胶发生体积相变。

In addition, the nozzle structure is complex and there are some parts of the factory of the nozzle is sealed with adhesive, glue is organic, most of the glue is impatient keto esters and organic solvents, alcohols, of course, including the nozzles on the sealant.

另外，喷头的结构很复杂，出厂的喷头有一些部位是用胶粘剂密封的，胶是有机物，大部分的胶是不耐酮酯醇类有机溶剂的，当然也包括喷头上的密封胶。
