Reviving dead pig organs 豬死亡後臟器恢復生機

285

美國研究人員表示,豬在死亡一小時後,其器官又恢復了生機,這是一項有望改變醫學的突破。

The technology is based around a synthetic fluid. It uses artificial blood to carry oxygen and prevent clots forming. And it contains 13 chemicals to support the body and interfere with the chemical processes that culminate in cells dying.

這項技術基於一種合成液體,它用人造血液來輸送氧氣,以防止血液凝固,合成液體包含13種化學物質,用來支持身體並干擾以細胞死亡而告終的化學過程。

Pigs were killed in the experiments, and after one hour, the fluid was rhythmically pumped through their blood vessels. You might expect the pig cells, those building blocks of their bodies, to have suffered permanent and devastating damage. However, the study in the journal Nature showed some function was restored – the cells had been partially revived.

豬在實驗中死亡,一小時後,合成液體被有節奏地灌注血管中,你可能認為豬體內的細胞,也就是豬身體的那些組成部份,遭受了永久性的嚴重損害,然而,發表在《自然》期刊上的這項研究表明,一些器官組織的功能得到了恢復,細胞部份恢復了活力。

The team at Yale University said they’d managed to persuade cells not to die. There was no sign of consciousness or brain activity in the pigs, and the experiments had ethical approval to take place.

這支耶魯大學的研究小組說,他們成功地 「說服」 細胞不要死亡,不過,並未在死亡後的豬體內檢測到有恢復意識或大腦活動的跡象,同時,實驗是在通過倫理審查批准後得以進行的。

The scientific goal is to use the technology to preserve human transplant organs for longer, so they can get to the patients who need them. There are even long-term ambitions to use it as a treatment for people starved of oxygen after drowning or a heart attack. All this will take further research, but the study has already been praised as an incredibly significant moment in medical research.

該實驗的科學目標是利用這項技術延長人體移植器官的保存時間,以幫助有需要的病人,長遠來看,科學家甚至希望能將其用於治療溺水或心臟病發作後缺氧的病人,要實現這些目標,都需要進一步的研究,但該研究已被譽為醫學研究中一個極為重要的時刻。

閱讀理解:請在讀完上文後,回答下列問題。

1. In the experiments, what carries oxygen around the bodies?

2. How long after the pigs were killed did the experiments begin?

3. True or false? The cells of the pigs were permanently damaged.

4. What are the scientific and long-term goals of the experiments?

答案  

1. In the experiments, what carries oxygen around the bodies?
Artificial blood carries oxygen around the bodies.

2. How long after the pigs were killed did the experiments begin?
The experiments began around one hour after the pigs were killed.

3. True or false? The cells of the pigs were permanently damaged.
False. The study in the journal Nature showed some function was restored – the cells had been partially revived.

4. What are the scientific and long-term goals of the experiments?
The aim is to preserve human transplant organs for longer and one day use it as a treatment for people starved of oxygen after drowning or a heart attack.
