Methods The cognitive impairment rat model was induced by hypodermic D-galactose injection and half fat feeder (6 weeks), the Morris water maze was used to screen the model rats, which were divided randomly into 4 groups (12 rats in each group): the model group, the hydrochloricdonepezil group (0.4 mg/kg, weight, sic passim), the low-dose Huannao Yicong Fang group (7 g crude drug/kg), the high-dose Huannao Yicong Fang group (14 g crude drug/kg), they were treated respectively by intragastric administration. Besides, a control group of 12 rats was set up, they were given tales doses of distilled water. After 4 weeks, the behavior of the rats was detected, the contents of plasma P-selectin and PAI-1 were measured by ELISA, also the hemorrheology was measured.

L-阿拉伯糖异构酶能分别催化L-阿拉伯糖和D-半乳糖异构为L-核酮糖和D-塔格糖，它是目前生物法生产新型功能性因子D-塔格糖最为有效的酶。

Iba 2002. Both the Arabidopsis fad5 mutant, which lacks an active chloroplast x-9 fatty acid desaturase and accumulates high levels of palmitic acid (16:0), and the fad6 mutant, which lacks an active x-6 fatty acid desaturase and accumulates high levels of palmitoleic acid (16:1) and oleic acid (18:1), have reduced levels of polyunsaturated fatty acids in the chloroplast galactolipids.

两个拟南芥突变体的叶绿体半乳糖脂含有较少的多不饱和脂肪酸：一种是拟南芥fad5突变体，它缺乏有活性的叶绿体的X-9脂肪酸去饱和酶，因而积累了高浓度的棕榈酸（ 16：0 ）；另一种是拟南芥fad6突变体，它缺乏一个有活性的 X - 6脂肪酸脱氢酶因而积累了高浓度的软脂酸（ 16：1 ）和油酸（ 18：1 ）。

Pectinase is heterogeneous group of related enzymes that hydrolyze the pectic substances, which can break down complex pectin into simpler molecules like galacturonic acids.

果胶酶是一类分解果胶质的酶的总称，它能将复杂的果胶分解为半乳糖醛酸等小分子。

The optimum broken temperature of the tomato had been confirmed by determining the impact of broken temperature on the activity of pectous enzyme and the solvency of the product.

针对加工番茄品种，通过研究破碎温度对其果胶酯酶和聚半乳糖醛酸酶活力的影响，以及破碎温度对产品的冲调性的影响，确定番茄合适的破碎温度。

The results showed that film packaging obviously decreased the weight loss and rotted rate, and to some extent decreased the respiration rate and slowed down the reduction of anthocyanin content, inhibited polygalacturonase and pectinesterase activities. But the decrease of total soluble solids, vitamin C and protopectin contents were slightly affected by packaging film.

结果表明，薄膜包装对降低果实失重率和腐烂率具有较好的效果；对降低呼吸强度、抑制多聚半乳糖醛酸酶和果胶酯酶的活性以及花色苷含量的下降有一定效果；对减缓贮藏期间可溶性固形物、维生素C和原果胶含量的下降无明显影响。

In order to understand the changes in physiology and the storability of blueberry fruits introduced to southern part of China, and to provide scientific basis for suitable packaging materials, changes of total soluble solid content, vitamin C content, acetaldehyde content, ethanol content, protopectin content and anthocyanin content, respiration rate, polygalacturonase and pectinesterase activities, weight loss and rotted rate of blueberry fruit warn investigated. Different packaging films were used, and the storage temperature was under 2℃.
