Hence the great interest in animal-to-human transplants, known as xenografts or xenotransplants (from the Greek work xenos, meaning strange of foreign) (56) most scientists believe is the only long-term solution to the organ (57) . There have been attempts at xenotransplants (58) the beginning of this century but neither has been successful; the longest (59) was a 20-day-old baby called Fae, who in 1984 was (60) the heart of a baboon.
The main (61) with any organ transplant is that the immune system of the patient receiving the organ sees the transplant organ (62) an invader. The immune system therefore launches a massive attack on the invader, activating enzymes knows as complement, which attack the (63) body, eventually killing the patient as well. This rejection has been (64) when transplanting human organs between humans by the close matching of tissue and the long-term use of drugs known as immuno-suppressants, first introduced just over ten years ago. With xenotranplants, however, rejection is even more (65) ; a normal pig's heart, for example, transfuses with human blood can be destroyed in 15 minutes.

1. Organ donation (捐献) and transplantation (移植) refers to the process by which organs or tissues from one person are put into another person's body.
2. The number of people needing a transplant continues to rise faster than the number of donors. A- bout 3,700 transplant candidates are added to the national waiting list each month. Each day, about 77 people receive organ transplants. However, 18 people die each day waiting for transplants that can't take place because of the shortage of donated organs.
3. There are no age limits on who can donate. Newborns as well as senior citizens have been organ donors. If you are under age 18, you must have a parent's or guardian's consent (同意). If you are 18 years or older, you can show you want to be an organ and tissue donor by signing a donor card.
4. Many people think that if they agree to donate their organs, the doctor or the emergency room staff won't work as hard to save their life. This is not true. The transplant team is completely separate from the medical staff working to save your life. The transplant team does not become involved with you until doctors have determined that all possible efforts to save your life have failed.
5. If you need an organ transplant, your doctor will help you get on the national waiting list. Your name will be added to a pool of names. When an organ donor becomes available, all the patients in the pool are compared to that donor. Factors such as blood and tissue type, size of the organ, medical urgency (紧急) of the patient's illness, time already spent on the waiting list, and distance between donor and recipient (授受者) are considered.
A. Quality of donated organs
B. Benefits of organ donation
C. Distribution of donated organs
D. Quality of donor medical care
E. Age limits for organ donation
F. Status of organ donation and transplantation
