[The relationship between eosinophilia and parameters of systemic and local adaptive immunity in patients with polypous rhinosinusitis].

Results of the study on adaptive immunity in patients with polypous rhinosinusitis (PRS) proved to depend on the degree of eosinophilia in the peripheral blood. The patients were allocated to two groups, one comprised of those having up to 150 eosinophils per 1 microliter the other of the patients with a higher eosinophil concentration. Patients of the former group had a significantly reduced number of CD3+, CD4+, CD8+, and CD20+cells in the peripheral blood that may indicate the necessity of administering immunotropic agents.

[Correlation between immunohistochemical indices of adenoid vegetations and health of ailing children].

We studied correlations between clinical characteristics of ailing children and their immunohistochemical parameters. Clinical status was assessed by the degree of adenoid vegetations, duration of the disease, the presence of chronic tonsillitis or its combination with adenoiditis. We used the following immunohistochemical parameters: the level of CD3+ in histological slices and the presence or absence of IgA-producing cells.
