猪死亡后脏器恢复生机-凯发k8官网

美国研究人员表示，猪在死亡一小时后，其器官又恢复了生机，这是一项有望改变医学的突破。

 

the technology is based around a ¹ fluid. it uses artificial blood to carry oxygen and prevent ² forming. and it contains 13 chemicals to support the body and ³ with the chemical processes that ⁴ in cells dying.

这项技术基于一种合成液体。它用人造血液来输送氧气，以防止血液凝固。合成液体包含13种化学物质，用来支持身体并干扰以细胞死亡而告终的化学过程。

 

pigs were killed in the experiments, and after one hour, the fluid was ⁵ pumped through their blood ⁶. you might expect the pig cells, those building blocks of their bodies, to have suffered permanent and ⁷ damage. however, the study in the journal nature showed some function was restored – the cells had been ⁸ revived.

猪在实验中死亡，一小时后，合成液体被有节奏地灌注血管中。你可能认为猪体内的细胞，也就是猪身体的基石，遭受了永久性的严重损害。然而，发表在《自然》期刊上的这项研究表明，一些器官组织的功能得到了恢复，细胞部分恢复了活力。

 

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 ⁹ approval to take place.

这支耶鲁大学的研究小组说，他们成功地 “说服” 细胞不要死亡。不过，并未在死亡后的猪体内检测到有恢复意识或大脑活动的迹象，同时，实验是在通过伦理审查批准后得以进行的。

 

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.

该实验的科学目标是利用这项技术延长人体移植器官的保存时间，以帮助有需要的病人。长远来看，科学家甚至希望能将其用于治疗溺水或心脏病发作后缺氧的病人。要实现这些目标，都需要进一步的研究，但该研究已被誉为医学研究中一个极为重要的时刻。
