[The state of antigen-dependent immunity system in children with chronic tonsillitis].

245 children aged 7-14 years with decompensated chronic tonsillitis were examined and treated in Anapa health resort. Before therapy the children had subnormal concentration of CD3+, CD4+/CD8+, elevated absolute and relative concentration of CD16+, low concentration of salivary IgA and SIgA combined with high serum IgM. The treatment brought a positive trend in the above indices, but CD16+, serum IgA and salivary SIgA remained higher than in controls.

[Antigen-independent factors of the system of immunity in patients with inflammatory processes of the maxillofacial area of staphylococcal etiology].

The course of severe acute and chronic odontogenic purulent inflammatory staphylococcal disorders involves the depression of cellular (myeloperoxidase, cation proteins of the neutrophilic leucocytes) and humoral (hemolytic complement and the blood serum bacteriostatic activities) antigen-independent immune factors. The differentiated immunomodulating therapy is recommended in such cases.

[Antigen-specific and antigen-nonspecific reactions of the immunity system in vaccination with a purified concentrated staphylococcal anatoxin].

Immunization with purified and concentrated staphylococcal toxoid leads to the rapid 12-fold rise of the level of anti-alpha-toxin and to the 17-fold rise of the titres of antibodies to extracellular staphylococcal products. At the period of immunization phasic changes in cell-mediated and humoral immunity characteristics, indicative of the state of the nonspecific resistance system, can be observed. These changes consist in the transient suppression of phagocytosis, including a decrease in the activity of intraleukocytic bactericidal systems (myeloperoxidase and cation protein), a decrease in the activity of the complement and the bactericidal activity of the blood serum, which should be taken into account when using this immune preparation for therapy.
