1. Experts  say the first transplant operation was carried out in 1823. By 1863, a French  scientist showed that the body rejects tissue transplants from one person to  another.

2. The  organ most commonly transplanted is the kidney. The success rate of kidney  transplants is very high. Some kidney transplant patients have survived for  more than forty years.

3. Another commonly transplanted organ is the liver. Doctors can remove  part of a liver from a person and place it into a patient who has liver  failure.

4. Other  tissue transplants involve skin, bone marrow, blood vessels and corneas.  Corneal transplants improve the sight of people whose eyes have been damaged  by injury or infection.

5. Health  care workers around the world say organ and tissue transplants save thousands  of lives. They urge people to consider giving permission to use their organs  for transplant operations if they should die unexpectedly.

专家说，第一个移植手术施行于1823年。到了1863，一位法国科学家发现人体排异从一个人移植到另一个人的组织。

最常见移植的器官是肾脏。肾脏移植手术的成功率很高。一些肾移植患者存活超过四十年。

另一个常见移植的器官是肝脏。医生可以取某个人的一部分肝移植到患肝衰竭的病人身上。

其他的组织移植涉及皮肤、骨髓、血管和角膜。角膜移植改善那些眼睛已经受到伤害或感染的患者的视力。

全世界卫生保健工作者说，器官和组织移植挽救成千上万人的生命。他们敦促人们考虑万一他们意外死亡，要允许他们的器官用于移植手术。
