小编摘要:碱式水杨酸铋中的有效成分为一种叫做碱式水杨酸盐的化合物。这种化合物作用于消化道,具有抗腹泻、抗菌以及解酸的作用。铋与唾液和胃肠道中微量的硫作用会生成一种黑色的物质——硫化铋。

 Black Tongues and Stomach Aches



Don: Oh, no, Yaël, I think I'm having a medical emergency. Quick! Call an ambulance.
Yaël: A medical emergency, Don? Are you sure? You look fine to me!
D: But I'm not. This morning, I had a terrible stomach ache. And now, now look at my tongue. Oh, it's all black. Surely, I'm dying, and you don't even care!
Y: Relax, Don! Of course I care. But you really dying?
D: But my tongue......
Y: I can tell you exactly what the problem is!
D: You can? But you are not a doctor!
Y: But I do read the contrary indications before taking medicine.
D: Un-huh!
Y: You said you had a stomachache, right? And I'll bet you 5 dollars that you have took some Pepto Bismol for it?
D: Wow! You must be psychic. How do you know?
Y: Well, the active ingredient in Pepto Bismol is a compound called bismuth subsalicylate.
D: Bismuth subsalicylate, so?
Y: This compound has anti-diarrheal, anti-bacterial, and antacid effect on the digestive tract.
D: Which is why Pepto helps with stomach discomfort.
Y: Right, but the thing is, when the bismuth combines with the trace amounts of sulfur in your saliva and in your gastrointestinal tract, it reacts to form a black substance called bismuth sulfide.
D: Bismuth sulfide, sounds dangerous!
Y: It isn't. But that's where the discoloration on your tongue comes from. And bismuth sulfide can also temporarily darken the stool. It’s a common enough side-effect that it’s listed in the package information, which you really should get in the habit of reading.
In a couple of days everything will back to normal.
D: Yaël, you saved my life.
Y: Not really...


黑舌头与胃痛

Don: 我的天呐,Y,我想我是染上什么急病啦!赶快!叫救护车!
Yaël: 急病?你确定?你看起来气色不错啊!
D: 我不觉得我很好啊。今天早上我胃疼得特别厉害。可现在…现在,你看我的舌头。整个舌头都是黑的!好吧,我都要死了,你一点也不关心我!
Y: Don,别太紧张好不好!我绝对是关心你的,但你确定你就要“去”了?
D: 可我的舌头……
Y: 我可以告诉你你的舌头究竟是怎么回事!
D: 你?可你并不是医生啊!
Y: 但是我每次吃药之前都会看说明书,看服药后会有什么副作用。
D: 嗯哼!
Y: 你说你胃痛,对吧?我和你赌5美元,你是不是服用了碱式水杨酸铋口服混悬液?
D: 神啦!你怎么知道的呢?
Y: 碱式水杨酸铋中的有效成分为一种叫做碱式水杨酸盐的化合物。
D: 碱式水杨酸盐,所以说?
Y: 这种化合物作用于消化道,具有抗腹泻、抗菌以及解酸的作用。
D: 这就是为什么碱式水杨酸铋能缓解胃部不适。
Y: 嗯。但是,铋与唾液和胃肠道中微量的硫作用会生成一种黑色的物质——硫化铋。
D: 硫化铋,听起来都觉得很危险!
Y: 这倒不是。但硫化铋就是将你的舌头变黑的罪魁祸首。而且,硫化铋还会使排泄物变黑。这是很常见的一种副作用,药品的包装盒上就列出来了的。所以啊,在吃药前一定要养成看说明的好习惯。放心了吧,要不了几天就恢复正常了。
D: Yaël,你救了我一命啊。
Y: 怎么会……
