[Large granule-containing lymphocytes in patients with infectious mononucleosis].

A study of 50 children with infectious mononucleosis is presented. Results indicate that the content of large granule-containing lymphocytes corresponds to the severity of the clinical course of infectious mononucleosis. Absence of large granule-containing lymphocytes evidences severe course of the disease while their appearance favoured normal reconvalescence of patients.

[The functional activity of the natural killers in patients with infectious mononucleosis and other viral infections].

The natural killer activity (NKA) and content of large granule-containing lymphocytes (LGL) were determined in 50 patients with infectious mononucleosis and in 36 patients with other viral infections. Results indicate that in 27 of 50 patients with infectious mononucleosis the number of LGL was less than 5% or equalled O. In 12 patients with infectious mononucleosis the number of LGL was 5% and in 11 children it was 5-20%.
