[Characteristics of the development of immunity in healthy children during the first year of life].
Studies of the levels of serum IgA, IgG, and IgM, of B and T lymphocyte function in 20 neonates of days 7-8 of life (funic blood) and their mothers, in children aged 1,3,6,9 and 12 months made it possible to define the characteristic features of the establishment of humoral and cellular immunity during the first year of the child's life. The children placed under observation were normal as regards their physical and psychomotor development and had no infectious or inflammatory diseases. The neonates were characterized by high activity of T lymphocytes, the lack of IgA and traces of IgM, and the high level of IgG in blood serum. The least IgG concentration was seen at an age of 1 month. The data obtained will permit a proper assessment of the changes occurring in the child's immune status during different diseases. The changes should be taken into consideration in carrying out preventive and treatment measures during the first year of the child's life.
