Transplanting Man’s Heart
I.
First Thoughts
Can you tell when you first knew about the
transplanting man’s heart.
How did you do this?

III. Read the text and do the tasks following it.
On January 2, 1968, an amazing occurrence in the history
of medicine took place. On that day a South African doctor,
Christian Barnard, successfully transplanted a human heart
into a man named Philip Blaiberg. The technique he used in
performing his surgery had been developed in 1959.
Although very many organ transplants are still being
performed, they are slightly less publicized today than they
were in 1968 and 1969. The original feelings of success wore
off quickly when the doctors discovered that they had not
completely solved all the problems of such operations. One of
the biggest problems is the fact that the patient's system is not
always willing to accept a foreign organ. It works against,
rather than with it. When this happens, the transplant is a fail-
ure, and the patient's life is in danger. On August 17, 1969,
Doctor Barnard's patient died because his body rejected his
new heart.
The history of transplanting human organs began in the
1930s. The first attempts were made on the cornea of the eye.
Since the cornea has no blood vessels, there was no necessity
of typing the patient and donor's antigens. Most of these
operations were successful.
Surgeons first tried to transplant a kidney in the early
1950s. To avoid the need for typing, the donor and recipient at
that time were twins. For a number of years, such an operation
was only successful when performed on twins. But by 1969,
due to the development of agents that would prevent rejection,
kidney transplants were made successfully on unrelated
persons. If a patient survived the first three months after the
operation, he was given an eighty percent chance of living
