Results The ponderal index of brain, thoracic gland and spleen and SOD activity are significantly decreased, while the MDA content increased (P.01) in D-galactose-induced subacute mice. Shouwu soft capsule can improve the ponderal index of brain, thoracic gland and spleen and the SOD activity in blood serum and brain tissue and reduce MDA content.

Hypodermic inject 1.2% D-galactose liquor (0.1mL/10g) by the nape of mice for 40 days. Observe: the ponderal index of brain, thoracic gland and spleen and the content variation of SOD and MDA in blood serum and brain tissue.

小鼠颈背部皮下注射1.2%D-半乳糖溶液0.1mL/10g鼠重，连续造模40天，并以空白组作对照，观察首乌软胶囊对亚急性衰老小鼠脑、胸腺、脾指数、自由基代谢指标血清和脑组织中超氧化物歧化酶和丙二醛含量的变化。

Two pairs of primers (TS5/TS11 and S18/S19) were used for the PCR method. Positive PCR results were obtained after the 18-hour preculture (6 h in lactose broth at 37℃ followed by 12 h in Rappaport-Vassiliadis broth at 42℃) for spiked raw and irradiated meats with or without freezing treatment.

试验以经过或未经过冷冻处理之加菌的鸡绞肉及辐射鸡绞肉，采用乳糖培养液於37℃培养6 h，续以Rappaport-Vassiliadis 培养液於42℃培养12 h之预培养，再配合PCR法，均可检测出沙门氏杆菌。

In the preformulation studies, UV absorption characteristics, solubility and stability of the drug in the different media were determined, the physico -chemical compatibility between the drug and nine kinds of excipients was observed using DSC analysis.

在处方前研究中，对盐酸尼卡地平的紫外吸收特性、不同介质中的溶解度和稳定性进行了测定，并利用DSC法考察了该药物与九种辅料（EC，HPMC，PVP，PEG6000，MCC，乳糖，淀粉，硬脂酸镁，SLS等）间的物理化学相容性。

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℃.

为了解引种到我国南方栽培的蓝浆果鲜果低温贮藏期间的生理变化状况，并为保鲜贮藏选择适宜的包装材料提供科学依据，研究了在2℃条件下，不同薄膜包装处理对蓝浆果果实贮藏期间可溶性固形物、维生素C、乙醛、乙醇、原果胶和花色苷的含量，以及呼吸强度、多聚半乳糖醛酸酶和果胶甲酯酶活性、失重率、腐烂率变化的影响。

The activity of polygalacturonase,PME,cellulase and the soluble pectin content of MA stor-age were significantly lower than those of control; while the flesh firmness,cellulose content ,protopectin content were sig-nificantly higher than those of control. Results showed that MA storage retarded the softening process of mulberry fruit.

研究了在(2±1)℃下，MA贮藏对桑果细胞壁组分和水解酶活性的影响，结果表明：MA贮藏可抑制桑果呼吸强度和乙烯释放量，MA贮藏桑果的纤维素酶、果胶甲酯酶和多聚半乳糖醛酸酶等细胞壁水解酶活性和水溶性果胶含量显著低于对照，而果实的纤维素和原果胶含量显著高于对照，从而延缓桑果的软化。

However, production of pyruvaldehyde in galactose/glycine system was much less than that in glucose/glycine system at 60°C.

糖类的初浓度对褐变速率之影响，在1.2%~4.8%之间呈线性正相关；其中羊乳糖／甘胺酸系统的褐变速率大於葡萄糖／甘胺酸系统。

Glucose/glycine and galactose /glycine model systems used to study the effects of sugar, temperature and concentration of sugar on Maillard browning and production of pyruvaldehyde.

本研究以葡萄糖／甘胺酸及半乳糖／甘胺酸为模式系统，探讨温度及糖浓度对 pH值。

The yield of pyruvaldehyde in glucose/glycine system (181□g/100ml)was3.6 folds that of galactose/glycine system (50□g/100ml)at 48 hr,We also founded that higher tmeperature promoted the change of pH, which in turn effect more significantly on Maillard reaction.

在丙酮醛产量方面，45°C组葡萄系统在6084小时后才开始产生且量较少；而60°C组葡萄糖系统其产量於48小时达至最高（181□g/100ml），此时丙酮醛的产量为乳糖组（50□g/100ml ）的3.6倍，之后有下降的趋势，其中浓度的效应较不明显。

This one mode pays close attention to network credence foundation of the businessman very much.

这一模式非常关注商人的网络信用基础。
