2、hin an individual,between individuals of the same species,or between individuals of different species.Background informationIn most cases,human material for transplantation is obtained from a deceased donor.Successful programs for the procurement of human material for transplantation from deceased d
3、onors from various cultural,religious and economic backgrounds constitute potential models.Background informationThe need for communities,including health professionals,to become better educated about transplantation is widely recognized as a key to the success of such programs.However,despite the f
4、requent use of materials donated from deceased donors,the donation of materials from living donors is necessary for some types of transplants or to compensate for the limited supply of material available from deceased donors in order to meet patient needs.Living donation is thus practiced despite th
5、e fact that it involves risks for the donor that may not be negligible.Background informationThe procurement of human material for transplantation from deceased or living donors and the subsequent allogeneic transplantation entail ethical and safety risks for both the donor and the recipient.Health
6、authorities must provide effective oversight of all aspects of transplantation in order to control these risks.Background informationThis oversight is also essential for gaining public support by developing and justifying trust in the procurement organization,particularly since donations are often m
7、otivated by altruism and generosity.In addition,the decision to be a donor is often based on the understanding that a contribution to the availability of transplant resources may someday benefit the health needs of the donors family.(http:/www.who.int/transplantation/donation/en/index.html,http:/www

25、small intestine transplantp 1996 U.S.surgeons at Barnes Hospital in St.Louis,University of California,San Francisco,and Stanford University Hospital perform split-liver transplantshttp:/ informationGlobal analysis of the textOrgan transplants are faced with a series of challenges:outdate of relevant
26、 policies,insufficient organ supply,disputable organ procurement policies etc.The first human context to consider is the dignity and integrity of the human body and the second is the obligations and limits of medicine.Besides,such questions as,“whose wishes should finally prevail in determining whet
27、her organs are taken or not and what is the meaning of autonomy”should also be listed as elements while considering organ transplants.Many individuals have given themselves(literally)to save the life of another,and yet the unequivocal protection of those who are not-yet-dead(but would be useful if t
28、hey were)has been called into question.(Para.3)Detailed study of the textpMeaning:Many people have donated their organ(s)to save other people.However,questions remain about the best way to protect those who are close to death.Protection is necessary because the persons death will benefit others thro
29、ugh transplanted organs.Detailed study of the textpunequivocal:pletely clear and without any possibility of doubt.pExample:To such a rude question,his answer is an unequivocal“no.”pcall something into/in question:to cast doubt on somethingpExample:These findings call into question the legitimacy of
30、the proceedings.“The human body(dead or alive)has not been reduced to mere property,and yet the desperation of watching thousands of individuals die every year while whether monetary incentives should be used in an effort to increase organ supply.(Para.3)Detailed study of the textpMeaning:The human
31、body cannot be considered as property.However we feel despair when we notice many people die every year while waiting for suitable organs.This situation has aroused a debate about whether money could be given(to donors)in order to increase the organ supply.Detailed study of the text“The Other bills
32、offered tax credits to individuals who donate organs(or credits to their surviving families)or reimbursement of the costs incurred by living donors.(Para.4)Detailed study of the textp Meaning:Other bills offered tax deduction to organ donors(or the donors family members)or compensation for the costs
33、 incurred by living donors.Detailed study of the textDetailed study of the textptax credit:an amount of money on which you do not have to pay taxpExample:The president proposed to provide tax credits to businesses that allow workers time off.preimbursement:compensation paid(to someone)for damages or
34、 losses or money already spent etc.pExample:He received reimbursement for his travel expenses.has endorsed the idea of a pilot program that would partially reimburse surviving families for the funeral expenses.(Para.4)Detailed study of the textpMeaning:.has approved of the idea of a trial activity t
35、hat would partially compensate the surviving families for the funeral expenses.Detailed study of the textp endorse:approve ofp Example:The plan does not explicitly endorse the private ownership of land.p pilot program:activity planned as a test or trialp Example:Under a pilot program New Zealand wil
36、l grant visas to 5,000 guest workers this year.And yet,it suggests that an individuals body has meaning only because it is useful;that the body is a tool individuals have rather than what individuals are.(Para.5)Detailed study of the textpMeaning:The statement that organs are no use to dead individu
37、als implies that human bodies are utilitarian but not connected to our inner beings.In the case of organ transplantation,this“violation”is done to one person,living or dead,in order to save another with possibilities both for great charity and great coercion that this intervention entails.(Para.6)De
38、tailed study of the textpMeaning:In the case of organ transplantation,this“violation”is done to one person,living or dead,in order to save another,which might mean great charity to the person who receive the organ and great oppression to the organ donor.p coercion:the act of compelling by force of a
39、uthorityp Example:He claimed he had only acted under coercion.Detailed study of the textAnd yet,if saving the most possible lives while inflicting the least harm on the living were the only significant human obligation,then our policy on organ transplantation(not to mention human experimentation)wou
40、ld be very different.(Para.7)Detailed study of the textpMeaning:Our policy on organ transplantation would be different,and human experimentation would also be different,if the only criteria for our actions were to save the maximum amount of people through the minimum amount of harm to the living.p i
41、nflicton:to make someone suffer by imposing an unpleasant circumstancep Example:That pitiful man inflicted a great deal of suffering on his wife and children.Detailed study of the textThe obligation to heal as fundamental as it is to the good life and good society exists in concert(and sometimes in
42、conflict)with other human values.(Para.7)Detailed study of the textpMeaning:The obligation to heal is essential to a good life and a good society,but it works together with and sometimes against other human values.p in concert:jointly,together.This expression uses concert in the sense of“an agreemen
43、t of two or more persons”.p e.g.:When the mind is in concert with the body,one can accomplish a great deal.Detailed study of the textDoes autonomy mean having the right to dispose of ones body(or enter into contracts for ones body)in any way an individual sees fit?(Para.8)Detailed study of the textp
44、dispose of:to get rid of,throw outpExample:The Green Box project aims to collect unwanted mobile phones and electronic accessories,and dispose of them in an environmentally friendly way.proposals to compensate individuals for providing organs potentially entail their right to sell their organs to th
45、e highest bidder.(Para.9)Detailed study of the textpMeaning:The proposals to compensate organ donors could lead to organ donors selling their organs to those who give the highest price.Detailed study of the textpentail:v.to make it necessary to do somethingpExample:This complex plan for rescuing the
46、 pregnant woman entails considerable risks.this means that their claims can neither be written off in advance nor accepted at face value.(Para.9)Detailed study of the textpMeaning:that is to say that the claims associated with the policies cant be discarded/disregarded or accepted without further in
47、vestigation,because they have never been tested.p write off:to accept the loss or failure ofp Example:We will just have to write off the arrangement if we cant find the money for it.Detailed study of the textp accept/take something at face value:to accept a situation or accept what someone says,with
48、out thinking there may be a hidden meaning.p Example:You shouldnt always take his remarks at face value,you know,he is quite eccentric.Detailed study of the textWe must,as we judge these different policies,think about the meaning of organ transplantation in its fullness.(Para.10)Detailed study of th
49、e textpMeaning:When we comment on different policies,we should think about the meaning of organ transplantation in all aspects.pfullness:completenesspExample:In the fullness of her joy,she could hardly speak.Thinking about public policy in this area means balancing these different realities and faci
50、ng soberly the moral costs and benefits of different policies.(Para.10)Detailed study of the textpMeaning:When thinking about the policies for an organ procurement system,we must take various realities into account and fully understand the moral costs and benefits of each policy as well.p sober:adj.
