Medicine in the twentieth century.
During the first seventy years of the twentieth century many discoveries were made in the treatment and prevention of disease. In 1901 Kari Landsteiner discovered the blood groups.
Some diseases are not caused by germs or infections but by the lack (недостаток, нехватка) of certain substances in our food. The discovery of vitamins in 1912 was very important to provide (обеспечить) people with a properly balanced diet.
During the two world wars, great advances were made in the field of plastic surgery, in which skin, bone, or muscle was taken from one part of the body and then was transplanted to a badly injured area in another part.
Great progress was made in the prevention and treatment of cardiovascular diseases, cancer, bacterial and viral infections. Insulin and penicillin were invented.
Renovation methods of diagnosing such as CT (computer tomography), MRT (magnetic resonance tomography), and ultrasonography have been developed.
