The underlying mechanism causing vasospasms isn't well understood, but likely involves vasoconstrictors like platelet thromboxane A2.

痉挛的机制不清，但可能与缩管分子TXA2有关。

But the aspirin also inhibits the protein thromboxane.

但阿司会抑制蛋白质素。

So, if you take aspirin, which stops thromboxane, that prevents blockages from forming in your blood vessels and keeps your blood flowing free.

因此， 如果您服用可阻素的阿司，就可以防管阻塞并保持液畅通。

In fact, the 1982 Nobel Prize winners also demonstrated that aspirin slows production of thromboxanes, chemicals that cause clumping of platelets, which in turn form blood clots.

事实上， 1982 年诺贝尔奖获得者还证明，阿司可以减缓凝恶烷的产生，凝恶烷是导致小板凝集的化学物质，进而形成块。
