在西班牙语中被称为 “死亡之树”
It produces a thick sap
它产生一种浓稠的汁液
that oozes out of its fruit, leaves, and bark,
从它的果实 叶子和树皮中渗出来
and touching it will leave you with blisters
触摸到这种汁液 你就会起水泡
that you’d expect from a severe burn.

If it’s raining, DO NOT STAND UNDER THIS TREE.

One of the toxic compounds in that sap is water-soluble,
树液中的一种有毒化合物是水溶性的
which means it can dissolve in those raindrops and land on you.
这意味着它可以溶解在雨滴中 落在你身上
The most toxic compound in the tree, phorbol,
树中毒性最大的化合物是佛波醇
interacts with a family of enzymes that modifies proteins
它与一类酶相互作用 而这类酶通过修改蛋白质
affects what messages are sent throughout our cells.
来影响我们细胞间的信息传递
Phorbol binds to these enzymes and causes an irreversible change
佛波醇与这些酶结合 导致不可逆的变化
so they’re left “ ON ”
所以它们被“打开”了
and sending those messages becomes a total mess.
发送的那些信息变得一团糟
This can lead to severe inflammation — hence the burn.
这可能导致严重的炎症 从而导致烧伤
Exposure to phorbol can cause some swelling,
接触佛波醇会引起一些肿胀
skin and throat burns, chest tightness,
皮肤和喉咙灼伤 胸闷
and if you eat it, uh… death.

but also…it’ll kill you.
但是……它也会杀了你
Its skin is covered in fluid that contains batrachotoxin.

Permanently.
是永久关闭!
This throws off their ability to
这会破坏它们向你的
send chemical signals to your heart and central nervous system,

An assassin shot a tiny pellet covered in ricin
一个刺客从一把伞的顶端
out of the tip of an umbrella…
将一个覆盖着蓖麻毒素的小颗粒
into his leg.
射到他的腿里
Ricin is a highly toxic protein in castor beans.
蓖麻毒素是蓖麻子中的一种剧毒蛋白质
You’d only come in contact with it
只有当你咀嚼了蓖麻籽或者吸入了
if you chewed the bean or breathed in castor bean powder
蓖麻籽粉 你才会接触到它
both highly unlikely.
这两种可能性都很小
Ricin stops our cells from creating new protein
蓖麻毒素通过永久性地
by permanently blocking the activity of ribosomes
阻止核糖体的活动来阻止我们的细胞产生新的蛋白质
those cellular machines we need to make all the protein in our cells.
核糖体是我们所需要的细胞产生所有蛋白质的细胞器
When a cell stops making protein it’ll die.
当一个细胞停止制造蛋白质时 它就会死亡
If you inhale ricin, within a few hours you’ll have a fever,
如果你吸入蓖麻毒素 几小时内你就会发烧
start coughing, and your lungs
开始咳嗽 你的肺
will stop working.
就会停止工作
If you eat it, you’ll have severe vomiting and diarrhea,

比如肌肉细胞
Botulinum toxin blocks acetylcholine,

which prevents muscle movement… and that’s dangerous for a lot of reasons.

You’ll see the first symptoms of botulism in someone’s face,
你会在某人脸上看到肉毒中毒的最初症状
as muscles that control their eyes and mouth begin to weaken.
