Aim to evaluate the feasibility of one simple method to establish model of venous thrombosis for studying the therapeutic effect of intracavitary ultrasonic therapy on venous thrombus of animal models. methods the lower limbs of 20 dogs were divided randomly into the experimental group and the control group. the femoral veins of the experimental group were ligated at the close and distant end respectively to slower the flow of blood. the veins in control group were operated but not ligated. then, the changes of the dogs ' lower limbs were observed and the femoral veins were excised for pathological examinations and examined to investigate the condition of thrombis in the veins at the 1st, 4th and 7th day respectively after operation. results all the dog ' s lower limbs in the experimental group swelled and were lame slightly, the thrombus came forth in all the 6 veins by pathologic study at the 1st day after operation. and it was opposite in the control group. in addition, the swelling of all the dogs ' lower limbs was aggravated and all the 14 femoral veins were filled with compact mixed thrombus at the 4th and 7th day after operation. and it was also opposite in the control group. conclusion the method to establish models of venous thrombosis by the simple ligation of close and distant end of the femoral veins can make thrombosis more approaching clinical course of thrombosis and is satisfying
目的為研究腔內超聲溶栓對動物模型靜脈血栓的療效而評價一種制備靜脈血栓模型方法的可行性.方法犬20隻採用自身對照研究，犬一側後肢股靜脈為實驗側，另一側為對照側.實驗側行股靜脈近、遠端分別結扎，人為造成犬後肢股靜脈血流緩慢;對照側行手術，但不結扎血管.然後于術后第1 ， 4 ， 7天分別觀察犬後肢變化，切取血管標本做病理觀察，了解血栓形成情況.結果術后第1天實驗側全部出現後肢腫脹，輕微跛行，病理切片顯示: 6條靜脈全部都形成血栓;對照側沒有出現後肢腫脹及跛行， 6條靜脈都無血栓形成.第4 ， 7天實驗側後肢腫脹加重，跛行，病理切片顯示:實驗側14條靜脈血栓充滿管腔，為混和血栓;對照側沒有出現後肢腫脹及跛行， 14條靜脈無血栓形成.結論採用靜脈單純結扎法制備犬靜脈血栓模型，血栓形成更接近臨床血栓形成過程 -

Thus, even if one of the above causes a change in control flow, the instructions at sequentially increasing addresses beyond the location of the change in control flow up to the next true end of the instruction group had the change of control flow not occurred, can still cause undefined values to be seen at the target of the change of control flow, if they cause a dependency violation
因而，即使上述的一個在控制項流中導致某個變化，在繼續增加的超出控制項流的地方一直到下次指令群真正結束的地址那些指令也不會發生，如果那些未知的值是不可靠的，那麼控制項流的變化目標導致了他們的出現。
