采用光—化学法在大鼠肠系膜微静脉建立活体血栓生成模型，研究了在急性（一次用药）与慢性（每日给药，一周）条件下阿司匹林的抗血栓作用。慢性阿司匹林用药组与生理盐水对照组相比，可以明显减缓血栓生长速度，延长血栓栓塞时间，表明阿司匹林对血栓形成有一定的抑制作用。而急性用药组的抗栓作用并不明显
The thrombosis model of aspirin was established by light-chemical method in the rat mesenteric venules. The antithrombotic effect of aspirin was studied in acute (once-only) and chronic (once-daily, one week) conditions. Chronic aspirin treatment group compared with saline control group, can significantly slow down the thrombus growth rate, prolong the thromboembolism time, indicating that aspirin on thrombosis have a certain inhibitory effect. However, the antithrombotic effect of the acute medication group was not obvious
