• In yet another scenario , an increase in amphibian predators , such as fish , leeches or turtles , may create more deformities by biting off tadpole limbs
  还有其他的状况，如鱼、水蛭或乌龟，有可能咬掉蝌蚪的腿，造成更多种形态的损伤。
• The research condition of leech on chemistry , pharmacology , clinical , toxicity , and to look into the future prospect of it are summarized
  摘要系统总结了近年来对水蛭的化学、药理、临床及毒性的研究概况，并展望了水蛭未来的发展前景。
• Abstract : hirudin is the potent antithrombotic factor found in nature . hirulog is a dind of peptides designed by imitating hirudin
  文摘:水蛭素是迄今发现的最强的天然凝血酶抑制剂，水蛭肽是模仿水蛭素与凝血酶的相互作用机制而合成的肽类化合物。
• Medical products give a very good expression to the scientific concepts and technologic features in respect of modernized traditional chinese medicines
  本公司经过多年的努力，基本完成了对中国南方水蛭资源分布及药食物种分类的调查和研究，并在水蛭医药应用技术方面取得了突破性的进展。
• This paper introduces their mechanism , function and clinical research , illustrates their advantages compated with heparin , believing that both hirudin and hirulog are new promising antithrombotic agents
  本文介绍了他们的作用机理及其临床研究，叙述了他们与肝素相比的优越之外，认为水蛭素与水蛭肽是两类非常有前途的抗栓新药。
• Their adventures involved swapping school dinners for donkey stew and guinea pig lasagne , staying in amazo - nian huts surrounded by tarantulas and leeches , and watching whales and tortoises in the galapagos islands

• Based on the structure and function analysis of hirudin , a potent thrombin inhibitor , and some platelet aggregation inhibitors , which contain the recognition sequence argglyasp as their functional motif , two chimeric antithrombotic molecules were designed by introducing rgd sequence to hirudin cterminus . these chimera genes were constructed by pcr and inserted into the expression vector pet21a , the constructs were confirmed by restriction enzyme digestion and dna sequence analysis . these recombinant plasmids were transformed into
  经限制酶消化和dna序列分析，证明两种重组质粒与设计完全一致。由于rgd -水蛭素嵌合基因上游连接了金黄色葡萄球菌蛋白a spa的信号肽序列，在iptg诱导下两种嵌合分子都获得了分泌表达，表达产物主要集中在细胞周质空间。
