微酸性

Results showed that casein could be completely removed of by adjusting pH 4.6 and centrifuging at 1100g.β-lactoglobulin was absorbed by the cation-exchange resin eluented by phosphate buffer. Through limiting the quantity of acid whey, the purity concentration percent of immunoglobulin was above 80% determined by SDS-PAGE. The ratio of activity of immunoglobulin losing decreased in simulated pepsin and the residual immunoglobulin content percentage was about 80% in 60 minutes.

实验结果表明：调节脱脂牛初乳pH=4.6采用1100g低速离心即可达到完全去除酪蛋白的良好效果；利用含有磷酸根基团的缓冲液处理阳离子树脂柱会专一吸附酸性乳清中的β—乳球蛋白，达到分离乳清中免疫球蛋白与β—乳球蛋白的良好效果，控制乳清样品处理量可使免疫球蛋白纯度达到80%以上；微胶囊化的免疫球蛋白可以延缓胃液对免疫球蛋白的消化分解，减缓免疫球蛋白活性损失速率，在60分钟内仍可保留80%的活性。

Then the optimal conditions were decided as follows: the ratio of wall-material to core-material should be 8.0 to 2.0, with ployacrylic sodium as dispersing emulsifier, NH4Cl as acid catalyst, and with the time of pouring catalyst being 2 h, the pH value at end point 2.0, the temperature of condensation reaction under control about 70℃, the reaction time 3 h, the stirring speed 1000 r/min.

研究了壁材与芯材的比例、分散乳化剂、催化剂、反应温度和搅拌速度5因素对微胶囊产品的影响，得出最优化的工艺为：壁材与芯材的比例为m：m=8.0：2.0，以聚丙烯酸钠为分散乳化剂，氯化铵为酸性催化剂，加入速度以2 h加完，终点pH值为2.0，缩聚反应温度控制在70℃左右，反应时间为3 h，搅拌速度为1000 r/min。

Cerebral hemorrhage rat models were established via injection of autologous arterial blood in caudate nucleus. Two days after modeling, 5 μL BrdU-labeled human embryonic NSCs suspension was transplanted at four points surrounding hematoma cavity in the rats. After 1 and 2 weeks, rats were sacrificed. Adjacent sections were doubly stained by BrdU/microtubule-associated protein 2 (MAP-2) and BrdU/glial fibrillary acidic protein.
