Objective : to establish a rat model of orthotopic gastric isotransplantation by using microsurgical techniques. methods : 70 sd rats were used in our experiment and 35 gastric trasplantations were carried out. in the donor ' s operation : after the spleen was resected and the proper liver artery was ligated, the stomach was perfused through the abdominal aorta. then the stomach was resected with its peripheral blood vessels including celiac trunk and the portal vein, etc. in the recipient operation : after the stomach and the spleen were reseeted, the implantation was performed by the following sequence : the end - to - side anastomosis between the portal veins. the end - to - end anastomosis between the celiac trunk and the left gastric artery. open the blood flow to observe the effect of the blood supply of the stomach. the end - to - end anastomosis between the duodenum. the end - to - end anastomosis between the cardiac and the esophagus. results : 35transplantations were carried out in which the operation success rate in the last 20 cases was 80 ( 16 / 20 ). the average operation time was 2. 35 h. the longest survival time was over three months. conclusions : the model of orthotopic gastric transplantation in rat was successfully established. it could be used to study the transplanted stomach in the abdominal multiviseeral transplantation and the reconstruction after the total gastrectomy
目的應用顯微外科技術，建立大鼠原位異體胃移植模型.方法70隻sd大鼠，行35例次的胃移值手術.供體手術，先切除脾臟，經腹主動脈行原位胃冷灌洗.將胃及其所屬血管，包括腹腔乾和門靜脈乾等一併切取.受體手術，先切除胃和脾臟，分別行供、受體間門靜脈的端側吻合，供體腹腔干與受體胃左動脈的端端吻合，然後開放血流.再行供體和受體十二指腸間端端吻合，賁門與食管端端吻合.結果在施行的35例手術，后20例中有16例成功，成功率為80 .最長存活者達3個月.結論成功地建立了大鼠原位異體胃移植類型.該模型可用於腹部多臟器移植中移植胃的相關研究及全胃切除術後代胃的研究 -
In our research, marked autologous fluorescent blood red cell is immitted into sd - rat body and the whole process is shown and recorded by microscope image system. after these processes, we can replay the recorded tape and sample images with video image card. then, we use sequence image processing to analysis the image of dark ground microscope
利用做過熒光標記的自身紅細胞注入sd大鼠體內，通過顯微圖象系統將整個過程以視頻信號的形式存貯，然後利用基於視頻圖象的採集卡，將流速變化過程回放采樣，得到暗視場下的熒光圖象，利用圖象分析和處理的方法，測定血流速度。 -
The promoter - probe vector phn117 in e. coli and phn127 in g " were further constructed by removing promoter while keeping sd sequence from phn115. a teta / tetr bidirectional promoter fragment from pbr322 was respectively cloned into phn117 and phn127 and the resulted colonies were all fluorescent
並經插入pbr322上665bpteta tetr雙向啟動子片段后得到的轉化子均發綠色熒光驗證，實現了wtgfp在大腸桿菌和華癸中生根瘤菌中的組成型表達。 -
This paper presents a algorithm that combined unary code and exp - golomb code. it switched separately in consideration of the difference between luma and chroma coefficients, instead of setting a marking bit which will bing loss at the same time, and also added some corresponding context models. it had been tested on sd, hd and cif, three types of sequence, and the bitrate had been saved by 1. 24134 %, 0. 10016 % and 0. 16029 % on average
針對這種情況，本文引入exp - golomb碼來減少較大的變換系數二值化的冗餘問題，提出了一種unary碼和exp - golomb碼相結合的的二進制化演算法，該演算法避免了設立標志位所帶來的附加損耗，分別針對于變換系數中的luma系數和chroma系數的概率分佈特點，採取了不同的自適應切換設置，並且相應地增加了概率模型。 -
The pa7 fragment was sequenced and several motifs similar to prokaryotic promoter elements such as - lobox, - 35box and up box were found. the sd sequence which was bound by ribosome and atg site were also found. the pat fragment was blast in genebank, but there is no its " homological sequence
對pa7片段的序列分析發現其距5 』端931bp ? 1091bp處具有原核生物典型基因啟動子的保守結構- 10區和- 35區，以及翻譯必需的sd序列和翻譯起始位點等。
