Clinical and immunological studies on healthy blood donors hepatitis B antibody carriers
Abstract:
Ten healthy blood donors persistently seropositive for anti-HBs and without a history of clinically overt viral hepatitis were studied. While physical examination and biochemical liver function tests exhibited normal values in all cases, immunologic studies revealed coexistence of a long-term anti-HBs carrier state with the presence of cell-mediated immunity to HBV antigens and autoantibodies in some. These results suggest a complex immunologic phenomenon underlying the development of the anti-HBs carrier state.

History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...
