The different fishes which are employed in the present studies are wild-type salmon, cultured salmon of freshwater and seawater, sea perch and fat greenling. The complete CT gene sequences of salmons are obtained by PCR amplification. The partial CT sequences of sea perch and fat greenling are obtained by in vitro cloning PCR method. Alignment of obtained CT sequences with other fish CT shows that CT appears to be well conserved among the same family. And the relative in taxonomy is far away, the similarity of different fish CTs is low. On the contrary, the closer the relative in taxonomy is, the higher the similarity of different fish CTs is. The sCT is expressed in pGEX-4T-X by recombinant form . We also succeed in the research of sCT expression alone by expression PCR. In addition, sCT antiserum is obtained using GST-sCT as antigen, and the high titer is tested by double immunodiffusion. In the rat bioassay, administration of 50 μg recombinant protein evoked significant hypocalcemia at 1 h after the data are analyzed by t-test.

本文用PCR方法克隆了野生鲑鱼、养殖鲑鱼的降钙素基因，并应用体外克隆PCR的方法首次克隆出鲈鱼、六线鱼降钙素的部分基因序列，通过对克隆的降钙素序列的比较研究，结果显示同一科的鱼降钙素序列保守性较高，同时，根据降钙素的部分氨基酸序列进行了降钙素相似性的比较研究，结果显示在分类学上，分类地位较远的鱼，其降钙素相似性较低，分类地位越接近的鱼，其降钙素相似性越高；我们利用谷胱甘肽S-转移酶(Glutathions S-transferase，GST)融合表达载体pGEX-4T-X对克隆的鲑鱼降钙素基因进行了融合表达研究，应用表达PCR的方法对降钙素基因的独立表达进行了初步的研究探索，并将纯化的融合蛋白作为抗原，获得了高效价的兔抗鲑鱼降钙素免疫血清；生物活性研究表明，大肠杆菌表达的融合蛋白具有显著的降血钙作用。

The results showed as follows:(1) the de-farming index of 479 investigated farm households is 79.21% with per capita area of de-farming slope farmland of 0.205 hm~2,per capita grain yield loss resulted from de-farming slope farmland of 74 kg and per capita allowance of 171 yuan from the government in 2003;(2) the de-farming allowance from the government has a bigger influence on a poor household,and if an allowance from the government would be stopped,the re-exploitation of partly de-farmed slope farmland is possible;(3) in 2003,per capita cash income of 479 investigated farm households is 1 492 yuan,and its sources mainly from floating employment,selling grain and greenstuff,de-farming allowance,selling products of domestic livestock and poultry and dealing dicker etc.;(4) in a few coming years,those employments of stable and higher earning will be firstly selected by farmers,and high expected value agriculture or rural commerce are going to become the leading livelihood of a good few farmers with some fund or skill.

结果表明：被调查农户人均退耕坡地0.205 hm2，退耕指数达79.21%；2003年479农户因退耕导致的粮食减产量人均74 kg，得到政府补贴人均171元；退耕补贴对贫困农户的影响程度较大，停止退耕补贴后存在反垦可能性。2003年被调查农户人均现金收入1492元，主要来源于外出打工、卖粮菜、退耕补贴、卖畜禽产品和做小生意等。未来几年，能获得稳定收入且报酬相对较高的行业是农民谋生的首选，有资金积累或一定技能的农户正在将生计转向高附加值农业或第三产业。
