Gamma Globulin

 

a fraction of globulins in blood plasma containing the most antibodies. In comparison with other protein fractions of the blood, gamma globulin has the slowest electrophoretic mobility. Gamma globulin is obtained either from the blood of donors or from blood from the placenta. So-called specific gamma globulin with an especially high content of antibodies to specific pathogens is isolated from the serum of humans or animals that have been immunized with the corresponding antigens. For example, anti-whooping-cough gamma globulin is prepared from the serum of humans hyperimmunized with whooping-cough vaccine; antirabies gamma globulin comes from the serum of horses hyperimmunized against rabies. Concentrated solutions of gamma globulin contain considerably more antibodies than the initial serums. In the USSR gamma globulin is produced in the form of a 10 percent solution (introduced intramuscularly). Gamma globulin is used for prevention and treatment of infectious diseases mainly in children (measles, whooping cough, poliomyelitis, epidemic hepatitis, and other diseases). Gamma globulin also has a certain nonspecific (stimulating) effect and for this reason it is prescribed for children with chronic inflammations, decline in appetite, and so on.
