　　Dr. Thomas Starzl, like all the pioneers of organ transplant, had tO live with failure.When he performed the worlds first liver transplant 25 years ago, the patient, a three-year-old boy, died on the operating table. The next four patients did not live long enough to get out of the hospital. But more determined, than discouraged, Starzl and his colleagues went back to their lab at the University of Colorado Medical School. They devisedtechniques to reduce the heavy bleeding during surgery, and they worked on better ways to prevent the recipient s immune system from rejecting the organ- an ever-present risk. Now, thanks to further refinements, about two thirds of all liver-transplant patients are living more than a year.

　　But the triumphs of the transplant surgeons have created another tragic problem: a severe shortage of donor organs. More and more people go on the waiting lists and there is wide disparitybetween supply and need, says one doctor. The American Council on Transplantation estimates that on any given day 15,000 Americans are waiting for or-gans. There is no shortage of actual organs; each year about 25,000 healthy people die un-expectedly in the United States, usually in accidents. The problem is that fewer than 20% become donors.

　　This trend persists despite laws designed to encourage organ recycling. Under the federal Anatomical Gift Act, a person can authorize the use of his organs after death by signing a statement. Legally, the next of kin can vetothese posthumousgifts, but surveys indicate that 70% to 80% of the public would not interfere with a family members decision. The bigger roadblock, according to some experts, is that physicians do not ask for donations, either because they fear offending grieving survivors or because they still regard some transplant procedures as experimental.

　　When there are not enough organs to go around, distributing the available ones be-comes a matter of deciding who will live and who will die. Once donors and potential recip-ients have been matched for body size and blood type, the sickest patients customarily go to the top of the local waiting list. Besides the seriousness of the patients condition, doc-tors base their choice on such criteria as the length of time the patient has been waiting and how long it will take to obtain an organ.

　　参考译文

　　跟所有进行器官移植手术的先驱一样，Thomas Starzl医生不得不承受失败。25年前，当他进行世界上第一例肝脏移植手术时，接受手术的三岁小患者死在了手术台上。接下来的四名接受器官移植的患者也未能活着走出医院。但是，Starzl和他的同事并没有气馁，们的决心反而更加坚定了，他们又回到了科罗拉多大学医学院的实验室里进行钻研。他们发明了一些技术用于减少病人在手术中的出血量，并且研究出更好的方法来防止病人的免疫系统对植入器官的排斥是手术中经常会出现的危险。如今，因为有了这些进一步的改进，在所有的接受肝脏移植手术的患者中，有2/3的人能活过一年。

　　但是，外科医生在器官移植手术上取得的成功引起了另外一个悲剧性问题：捐赠器官的严重缺乏。有医生曾表示：越来越多的人在等待接受手术，而器官的供求差异悬殊。美国的器官移植委员会估计，大约每天有1.5万名美国人在等待着器官以进行移植手术。事实上缺的不是器官;每年美国大约有2.5万名健康人死于非命，一般都是因事故死亡。而问题在于，这些人中，只有不到20%的人会成为器官捐赠者。

　　即使人们制定了法律来鼓励器官的重新利用，现有的事态还在继续。根据《联邦解剖捐赠法案》的规定，通过签署一项声明，一个人可以指定其死后器官的用途。从法律角度来说，该死者的近亲可以否决这种遗赠，但是有调查显示，70%到80%的人不会干涉他们家庭中某一成员的决定。实际上，一些专家发现，最大的问题是由于外科医生担心会惹怒那些沉浸在悲痛中的家属，或者是因为他们仍然认为器官移植处于试验阶段，所以他们一般不会主动提出让死者捐出器官。

　　当器官资源不足时，如何分配那些可利用的器官就成了一件决定生死的事情。一旦有器官接受者在体型和血型方面与捐赠者相匹配时，这些器官接受者中病情最严重的就自动成为候选名单中的首选之人。除此之外，医生在做决定让谁接受器官移植时，除了要考虑患者的病情的轻重，还要考虑患者等待时间的长短、多久能获得合适的器官
