时差N小时 肉毒杆菌毒素

In our beauty conscious culture, people will go to great lengths to improve their appearance. Liposuction, tummy tucks, silicone implants--it's all been done. But surely we wouldn't resort to injecting ourselves with a toxic¹ substance that causes botulism, would we? Of course we would, in the form of Botox injections, widely advertised as a quick, easy way to remove wrinkles and crow's-feet.

在这个崇尚美丽的文化里，人们会竭尽全力改善自己的外表。抽脂，紧腹手术，硅胶填充，应有尽有。但想必我们不会对自己射入一些会引起肉毒中毒的有毒物质，会吗？当然我们会注射肉毒杆菌毒素，它被大肆宣传为一种快速、简单除皱和眼角鱼尾纹的方法。

Botox is the marketing² name given to a neurotoxin called botulinum toxin³ A. This toxin comes from the bacterium⁴ that produces the poisons responsible for causing botulism. Botulism is a form of food poisoning, the most serious symptom of which is paralysis⁵.Botulism-related toxins⁶ attach to nerve endings, where they block their ability to trigger muscle contractions⁷. If muscles can't contract, they can't move, resulting in paralysis.

肉毒杆菌素只是市场对肉毒杆菌毒素A这种神经毒素的一个叫法。这种毒素来自细菌，它们可产生大量能引起肉毒中毒的毒素。肉毒中毒是食物中毒的一种，它最严重的临床表症就是身体瘫痪。肉毒毒素牵动神经末梢，阻止肌肉收缩，肌肉一旦不能收缩，肢体则无法运动，这样就导致瘫痪。

So why would anyone risk injecting Botox into his or her body? There are legitimate⁸ medical reasons, such as treating spasms⁹ and involuntary muscle contractions.Although the paralyzing effects are not permanent, they can last up to eight months.And as long as Botox is injected directly into a particular muscle group, there's little chance that it will spread to other parts of the body.

那么为什么人们还要冒险往体内注入肉毒杆菌呢？其中就有诸如治疗痉挛和无意识性肌肉收缩等合法医疗因素。虽然麻痹的作用不是永久性的，但也能持续八个月。只要肉毒杆菌毒素直接注入到特定的肌肉组织，就不太可能扩散至身体的其它区域。

As a beauty treatment, Botox does what it's meant to do: paralyze muscles. For example, injecting botox into muscle groups near the eyes will temporarily paralyze those muscles, keeping them from scrunching¹⁰ up. Consequently the wrinkles, or crow's feet, they cause temporarily disappear. In time, however, wrinkles reappear.Not even Botox can permanently¹¹ reverse the march of time.

对于整容来说，肉毒杆菌确实做了它该做的：麻痹肌肉。例如，在眼睛附近的肌肉组织注射肉毒杆菌毒素，会暂时性的麻痹那些肌肉，使它们不皱起。结果就是皱纹或眼角鱼尾纹会暂时性的消失。然而，时间一长皱纹会重新出现。即使是肉毒杆菌也不能让时光永远倒流。
