[Immunomorphological investigation of hypertrophied tonsils in children].

The immunohistochemical investigation of hypertrophied tonsils in children of different ages (group 1--up to 7 years old, group 2--7-11 years old, group 3--12 years and older) are presented. The expression and localization of viral antigen, sIgA and IgE, CD3+ and CD20+ cells in the tonsils tissue has studied. We've founded out a decreasing of viral antigens expression in the older age groups. The highest intensity of sIgA expression has been determined in the second group. The count of CD3+ cells in the germinal centers of follicles has increased in 2 and 3 groups.
