An agonist is a substance that mimics the action of a natural ligand, and I show you a couple of examples of agonists here.

激动剂是能够模拟天然配体分子的物质,在这里我给出了一些激动剂作为例子

Now, sometimes the agonist is the natural ligand itself and that's - an example of that is when you use insulin as a drug.

有时激动剂药物就是天然配体分子,例如将胰岛素作为药物使用

We've identified many drugs that stimulate insulin receptors, for example, but they're not exactly insulin, and those can potentially be used as agonist type drugs.

我们已经设计了很多,能够激活胰岛素受体的药物,但它们都不是和胰岛素分毫不差的,但都可以用作激动剂类药物

They can antagonize that reaction, and a result they affect blood rate.

受体阻断剂能够阻断这类作用,进而影响血液流速

One class of them is beta-blockers, they bind to beta-adrenergic receptors, which are receptors that exchange information between your nervous system and the contractile system that beats your heart and that causes the heartbeat.

一类药物是β阻断剂,它们与β肾上腺素受体结合,这种受体能够在神经系统和,控制心跳的心肌收缩系统之间传递信息,从而产生心跳
