title: [Frequency of acrocentric chromosomal associations and their silver staining in human lymphocytes in immune reactions].
abstract: Ag-staining of the nucleolar organizer regions of acrocentric chromosomes of T-lymphocytes did not change during the immune response in children with porotitis and in those being in contact with parotitis-suffering children, as well as in young adults previously immunized by staphylococcal anatoxin. This character displayed individual peculiarities. No differences in these age groups were detected. A positive correlation was found between the size of Ag-band and the ability of chromosomes to make associations. Ag-staining and participation of G-chromosomes in associations was higher than those markers in D-chromosomes.
