The results showed that the average contents of soil total potassium ( STK ) and soil available potassium ( SAK ) were ( 21 .

结果表明：供试土壤中速效钾的动态变化特征各异，其“最低值”的大小和出现的茬数也不相同。

Phage a has the ability of lysogenic conversion for production of SAK , but α has not .

α具有溶原性转换葡激酶能力，β则无。

The spatial distribution characteristics of SAK content in 2002 apeared as reducing trend from southeast to middle part of the study aera as a whole .

Error-prone PCR to introduce random mutations and screening of the resultant mutant libraries have been used to enhance the activity of wild-type Sak .

首先，本研究采用易错PCR法对野生型sak基因进行随机诱变，建立随机突变库，筛选活性提高的突变体。

According to SAK model , a relation between the fractal dimension and the attractive energy is derived , which indicates that the fractal dimension decreases as the attractive energy increasing .

根据SAK模型导出了分维度与相互作用能的关系，结果表明：随着粒子间相互吸引能的增加，聚集的分维度减小。

Objective : To establish a rabbit middle cerebral artery ( MCA ) embolic stroke model , and to study intra arterial thrombolysis with recombinant staphylokinase ( r Sak ) in this model .

目的：建立兔大脑中动脉（MCA）栓塞模型，并应用重组葡萄球菌激酶（r－Sak）进行动脉内溶栓治疗。

Objective To inspect the effects of recombinant staphylokinase ( r Sak ) and the changes of fibrinolytic activity in the systemic circulation in the treatment of experimental central retinal artery occlusion ( CRAO ) .

目的观察重组葡激酶（recombinantstaphylokinase，r-Sak）治疗实验性视网膜中央动脉阻塞（centralretinalarteryocclusion，CRAO）的效果及其对全身的影响。

It is a focus to study thrombosis , such as thrombin inhibitors , plasminogen activators ( t-PA , u-PA , SK , SAK etc ) and some thrombolytic enzymes .

凝血酶抑制剂、纤溶酶原激活剂（tPA、uPA、SK和SAK等）、蚯蚓纤溶酶和蛇毒抗凝血蛋白等是血栓类疾病领域的研究重点。

Staphlokinase ( Sak ) is a small extracellular protein secreted by numerous strains of staphylococcus aureus , many experiences indicated that Sak was a more protein and more fibrin-specific fibrinolytic agent .

葡萄球菌激酶（Staphylokinase），简称葡激酶（Sak），是金黄色葡萄球菌分泌的一种胞外蛋白。多项实验表明，葡激酶是一种极具潜力的溶栓药物。

Methods In the clinical trial , 15 healthy volunteers were divided into 5 groups and accepted r Sak with different doses ( 2.5,5,10,15,20 mg ) respectively . The influence on the indexes of coagulation and fibrinolysis system and the side effect were observed .

方法将15名健康志愿者分5组，分别给予不同剂量（2.5、5、10、15、20mg）的rSak，观察rSak对凝血及纤溶系统指标的影响及其副反应。
