Methods The model of subacutely aging rats were made by injecting Dgal into the rats, abdominal cavity continually. After lavaging HSWY, the apoptosis rate and the levels of Fas and FasL mRNA were measured by TUNEL and RTPCR; the expressions of Fas/Fasl protein were detected by SP immunocytochemistry.

采用D半乳糖连续腹腔注射致亚急性衰老大鼠模型，同时以何首乌饮灌胃作为延缓衰老组；造模后应用脱氧核糖核苷酸末端转移酶介导的缺口末端标记法检测各组大鼠卵巢细胞凋亡情况；测定各组Fas和FasL的信使核糖核酸水平；SP免疫组化法检测卵巢细胞Fas和FasL蛋白的表达情况。

Comparing with chitin and starch, the thermal stability of the sulphated polysaccharide Hal-A and heparin is lower. The results of TG- IR analysis demonstrate that Hal-A is decomposed into CO_2, H_2O, alcohols, oxo-compounds etc and remains mainly contain Na_2SO_4 and carbon.

与淀粉、肝素、甲壳素和半乳糖的热分析比较，含有硫酸酯的鲍鱼多糖和肝素热稳定性较低，含氨基的甲壳素最高，这反映出不同基团对多糖热稳定性的影响。

The yield of tagatose was 49.05%. As calcium acetate can be dissolved, and make some difficulty for desalt, thus usually phosphate acid replaced it.

但是由于醋酸钙可溶，不易脱盐，故一般用磷酸代替醋酸。D-塔格糖与D-半乳糖分离对D-塔格糖的产业化是有重要意义的。

Similar to that, compared to the mouse model of memory impairments of acquisition, retention and retrieval induced by scopolamine, sodium nitrite and ethanol D-galactose, the blank control group, SZF group and positive control group could prolong the latency and reduce errors in step-down test and avoiding dark test.The result bioassay showed that SZF group incresed the activity of SOD and level of TChE and decreased the level of MAD in mice brain tissue.

东莨菪碱、亚硝酸钠和乙醇分别诱导的小鼠学习记忆获得、巩固和再现障碍实验结果表明，与模型组比较，在跳台和避暗测试中，空白对照组、SZF复方和阳性对照组均能延长跳台实验和避暗实验的潜伏期(P.01，P.05)，均能减少实验中的错误次数(P.01，P.05)。D-半乳糖、东莨菪碱、亚硝酸钠和乙醇诱导的小鼠脑组织生化测定的结果显示，与模型组比较有显著差异，SZF复方表现为能使脑组织中总SOD活力上升，MDA含量降低，TChE含量上升。
