text: The first succesful organ transplant was a kidney transplant between twin brothers performed in Boston in 1954.  For many years afterwards, the only transplants done were kidneys between twin siblings.  Being twins made the kidneys genetically identical so there was no chance of rejection since immunosuppresant drugs were not available until the late 60's or early 70's.  In 1967 the first human heart transplant was attempted by Dr. Christian Bernard in Capetown South Africa.  The patient died a few days later.  Within a few years after this, cyclosporine was introduced and organ transplantation became a reality.  This was the first immunosuppresive drug that became available and solved the issue of rejection.  Since that time, transplatation of heart, livers, lungs, kidneys and pancreas have become common place.  New drugs have been developed that are more specific to fighting rejection rathe than suppressing the whole immune system and have fewer side effects.  Research continues into other transplants and better medications.
