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

痉挛的机制，可能与缩血管分子TXA2有关。

But the aspirin also inhibits the protein thromboxane.

阿司匹林也会抑制蛋白质血栓素。

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， 如果您服用可阻止血栓素的阿司匹林，就可以防止血管阻塞并保持血液。

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，阿司匹林可以减缓凝血恶烷的产生，凝血恶烷是导致血小板凝集的化学物质，进而形成血块。
