Immunochemical estimation of some proteins in Nigerian paired maternal and fetal blood.

The immune response in an individual is relevant to his survival, and this is especially true of people living in Africa where they are constantly challenged by a host of parasitic antigens. The antibodies which result from such immune response are found in the immunoglobulins: IgA, IgG, IgM, and IgD. Thus the concentration of these immune substances in the circulation provides some useful index of the immune state of the individual. Within the past 2 years immunochemical estima-tion of immunoglobulins at this institution and at a few other centres in parts of Africa has been concerned with immunoglobulin in the African
