Thederivatives of 5 kinds of monosaccharides Xyl, Ara, Man, Glc, Gal were detected anddetermined respectively by GC-MS. The influences of several factors, such asreductive time, reductive temperature, acetylating temperature and acetylating time,on recovery of monosaccharides were studied by orthogonal experiments. The resultsshowed that the reductive temp.

Methods With the model of aging mice induced by D-gal, the learning memory ability of mice was measured by using Y-maze, the contents of SOD and MDA in the cerebrums were determined by xanthine oxidation or TBA colorimetry ,the variations of above indices of mice after treatment with NGD were observed.

建立 D-半乳糖致小鼠衰老模型，以 Y型电迷宫检测其学习记忆能力，分别采用黄嘌呤氧化酶法、TBA比色法测定大脑 SOD活性和 MDA含量，观察小鼠服用神经生长液后上述指标的变化。

Maybe it is a new member of b-galactosidase family. bin2a mrna is upregulated by androgen and also epididymis-specific, majorly in caput epididymides.

所以，bin2a可能是b-半乳糖苷酶家族的新成员。bin2a表达受雄激素上调，其表达的组织专一性也很高，只在大鼠附睾有表达，并主要在附睾头部。

The agglutination for rabbit was the highest among erythrocytes of human, rabbit, common carp and crucian carp. The hemagglutinating activity for rabbit could not be inhibited by D-fructose, D-mannose, D-galactose, glucose, sucrose, manrmn, gamma-globulin and egg albumin, but inhibited by bovine-thyroglobulin, and the minimum inhibitory concentration was 3.10 mg/ml.

Results:It is suggested that the drug significantly protectes liver from CCl4,thioacetamide and galactosamine in mice and rats,lowers the activity of enzyme ALT in serum,shorten the sleep duration of CCl4-damaged mice induced by embuter,inhibites HBsAg in vitro,and potentiates non-specific immunity in mice and rats.

结果：研究表明，该药对四氯化碳、硫代乙酰胺和氨基半乳糖引起小鼠及大鼠的急性肝损伤有明显的保护作用，能降低谷丙转氨酶；缩短CCl4肝损伤小鼠戊巴比妥钠的睡眠时间；抑制体外乙肝病毒表面抗原；对非特异性免疫有一定增强作用。

The rats in treatment group were redivided into four groups: HSWY low dosage group, HSWY middle dosage group, HSWY high dosage group and Heshouwan group.
