The optimum temperature s and pH were(40℃,2.4)for stomach,(55℃,7.6) for pyloric caeca(45℃,8.0) for gut. The optimum temperature for protease activity was higher than that in the fish body. The highest activity of protease occurred in strong acidic condition in stomach,but in neutral or weak alkaline condition in pyloric caeca and gut.

Results:Three immunophenotypes were determined: MCs positive for tryptase, no immunodetectable chymase; MCs positive for chymase, no immunodetectable tryptase ; and MCs positive for tryptase and chymase .

结果：三种免疫表型被确定：肥大细胞的类胰蛋白酶阳性、类糜蛋白酶阴性；类糜蛋白酶阳性、类胰蛋白酶阴性和类胰蛋白酶阳性、类糜蛋白酶阳性。

Enzymes could enhance the deamidation rate of Gln residues. Nutrase was the most effective. The rate of deamidation by Nutrase after 6 hours at the given conditions were up to 40.85 percent, followed by alkaline enzyme and papain. Prozyme A, flavourzyme, pepsin had no obvious effect.

蛋白酶具有明显的水解酰胺基的作用，以中性蛋白酶为最，反应6小时，脱酰胺率高达40.85％，碱性蛋白酶和木瓜酶次之，复合酶A、风味酶和胃蛋白酶的作用较小。

Lactobacillus plantarum had lipolytic activity. Bacillus subtilis not only had the lipolysis but also had proteolysis.Single strains fermenting experiment showed that, the effect of different strain to the pH, acidity, the total amino acid were not signifient, Pediococcus pentosaceusand Lactobacillus plantarum could improve the content of free amino acid in dried beef.

研究结果表明：沃氏葡萄球菌、腐生葡萄球菌和植物乳杆菌只有脂肪酶活性，无蛋白酶活性；松鼠葡萄球具有弱蛋白酶活性；木糖葡萄球菌具有弱脂肪酶活性；戊糖片球菌具有脂肪酶活性，而蛋白酶活性较弱；枯草芽孢杆菌具有两种酶活性。

The free radical scavenging effects of Meretrix meretrix hydrolysates prepared with papain,neutral protease and acid protease were investigated.

利用正交实验研究了文蛤蛋白分别经木瓜蛋白酶、中性蛋白酶、酸性蛋白酶作用后酶解物对羟自由基和超氧自由基的清除作用，优化了水解条件，并对最佳清除率下的三种酶解物进行SephadexG50凝胶柱分离，测定酶解物中抗氧化活性肽的分子量分布。

This part is to explore the effect of rhEPO on neuromotor function,secondary pathology change and expression of Caspase-3, which was peritoneal injected at different time after rat traumatic spinal cord injury Method Wistar rat were randomized into normal group,sham operation group, blank control group and rhEPO group.

第二部分脊髓损伤后促红细胞生成素对Caspase-3表达的影响目的：半胱氨酸蛋白酶被认为是细胞凋亡过程中最重要的一系列蛋白酶，其中Caspase-3是最重要的蛋白酶，是多种凋亡途径的共同下游效应部分。

Urokinase-type plasminogen activator is a very important serine protease, which is best known for its role in the initiation of the pericellular proteolystic cascade.

尿激酶型纤溶酶原激活剂(Urokinase-Type Plasminogen Activator，uPA)是—种非常重要的丝氨酸蛋白酶。uPA不仅本身是一种蛋白酶，更重要的是，uPA能够激活一系列蛋白酶，降解细胞外基质。

We study the express of heparinase,matrix metalloproteinase MMP-2,MMP-14 and cadherin in the gastric cancer tissue and perigastric normal mucosal tissue,and make a statistics analysis between heparinase, matrix metalloproteinase MMP-2,MMP-14,E-cadherin and gastric cancer biological behavior.We hope to knom the possibility that heparinase,matrix metalloproteinase MMP-2,MMP-14,E-cadherin are regared as clinical screen index of the gastric cancer recrudescence or metastasis.

本文就肝素酶、基质金属蛋白酶MMP-2、MMP-14、钙粘蛋白在胃癌组织及胃周正常粘膜的表达进行了研究，并就肝素酶、基质金属蛋白酶MMP-2、MMP-14、钙粘蛋白与胃癌的生物学行为进行了统计学分析，以期了解肝素酶、基质金属蛋白酶MMP-2、MMP-14、钙粘蛋白作为胃癌复发或转移的临床筛选指标的可能性。

Full enzymatic synthesis of N-protected Leu-enkephalin was successfully achieved via 3+2synthetic route by α-chymotrypsin and thermolysin, and the Z-protected Leu-enkephalin phenylhydrazine was obtained in tert-amyl alcohol by thermolysin for the first time.

以3+2的合成路线使用α-胰凝乳蛋白酶和嗜热杆菌蛋白酶完成了N-保护的亮-脑啡肽的酶法全合成，并在第三戊醇中首次以嗜热杆菌蛋白酶为催化剂得到了Z-保护的亮-脑啡肽酰苯肼衍生物。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
