Study Abroad in West Germany and the Fall of the Berlin Wall

抄録

　In 1961, the Berlin Wall was built by East Germany all around West Berlin. East Berlin was governed by the Soviet Union, and West Berlin was governed by France, Great Britain, and the United States. West Berlin and West Germany were connected by autobahns, railroads and planes, and West Berlin developed with West Germany. On November 9, 1989, the Berlin Wall suddenly collapsed. Many people were destroying the Berlin Wall with a hammer, as if they vented their anger for years. The work to remove the Berlin Wall began the next day, and East and West Germany were unified on October 3, the following year.

　I tried two studies on liver transplantation in West Germany. One was an experimental study on the effects of the donor’s fasting and graft viability after liver transplantation, and the other was a study on the role of Kupffer cells in the induction of tolerance after liver transplantation. It has been suggested that poor nutritional status of donors promotes preservation injury and contributes to a decrease in the viability of the transplanted liver, and hepatic Kupffer cells are involved in the establishment of induction of specific immunological tolerance in donor specific blood transfusion.
