It is now well understood that asparagine synthetase is composed of two parts: a wedge-shaped place in the two antiparallel β-overlapping layers near the N-terminus that functions in glutamine hydrolysis; a C-terminus responsible for binding of Mg2+ ATP and aspartate.

现又明确天冬酰胺合成酶是由两部分组成：N基末端的两个反平行式β-折叠片层中的楔形部分是负责水解谷氨酰胺的活性部位；C基末端负责结合Mg2+ATP和天冬氨酸。

In control group(n=38) the patients were given aminophylline tablets in addition to common antiphlogistic nebulization treatment;while in treat group(n=42) the aminophilline load were applied to assist the common antiphlogistic nebulization treatment.results in comparison with control group,the patients in treat group were more fastly liberated from asthmatic couphing and dyspnea(p.05),needed fewer days in hospital(p.05) and had an elevated cure rate(p.05).conclusion aminophylline load application as the assistant way is an effective,safe and economical method to fastly alleviate the dyspnea caused by bronchiolitis.

结果 氨茶碱负荷量应用治疗毛细支气管炎可迅速缓解患儿的喘憋和呼吸困难，缩短住院天数和提高治愈率。结论在普通消炎雾化治疗基础上加用氨茶碱负荷量是快速缓解毛细支气管炎喘憋、呼吸困难的有效、安全、经济的方法之一。

Twenty varieties or materials of tomato with different resistance were used for experiment. Through testing the reaction condition and pH of extract of POD and PPO, identifying the genetic relationship of twenty varieties by POD isozyme and testing the biochemical indexes of resistance to ToMV, the main results were showed as follows:1. Classification of resistance: According to the campestral resistance to ToMV and the analysis experimental data ,the resistance of twenty varieties were divided into three kinds:z(1)resistant variety, including Zhong-za No9. Zao Hong-bao.

本试验以20个番茄品种或材料为试材，研究了过氧化物酶、多酚氧化酶酶液提取及反应适宜条件；应用POD同工酶对20个番茄材料进行亲缘关系的鉴定；对20份材料苗期室内接种ToMV后进行抗病性鉴定以及接种两周后所有材料POD、PPO、苯丙氨酸解氨酶的活性变化的研究，得出以下结论： 1。

MethodsFifty one patients with rheumatic heart disease were randomly divided into two groups: L arg group ( n =25) and control group ( n =26). For L arg group, L arg at 300mg/kg was given during operation.

术前将 5 1例拟行心瓣膜置换术的风湿性心脏病患者随机分成两组：L-精氨酸组(n=2 5 )，术中给予 30 0 mg/kgL -精氨酸治疗；对照组(n=2 6 )，术中给予等量的 5 %葡萄糖注射液。

Objective To develop an effectually secrete expression in Pichia pastoris and purification system of recombinant human Arginase, and to test the activity of recombinant Arg.

Western blot was used to examine the phosphorylation of NR2A in rat hippocampus. Results Both Src and Fyn antisense ODNs could decrease the phosphorylation of NR2A induced by cerebral ischemia/reperfusion, while administration of Src antisense ODNs had more suppressive effect on the phosphorylation of NR2A than Fyn antisense ODNs.
