[The indices of the humoral immunity and cytogram in pleural exudates of different etiologies]. / Pokazateli gumoral'nogo immuniteta i tsitogrammy pri plevral'nykh vypotakh razlichnoi étiologii.

A cytological and immunological examination of pleural exudates of different etiology indicates that tumour exudates differed from exudates of tuberculous and parapneumonic etiology by distinctly reduced level of immunoglobulin A as well as by an elevated content of circulating immune complexes. Prevalence of mesothelial cells accompanied by an increase of immunological indices in tumour exudates and their reduction in exudates in cases of cardiac pathology is to be considered as an unfavourable prognostic sign.

[Indices of local antiviral immunity in patients with chronic bronchitis]. / Pokazateli mestnogo protivovirusnogo immuniteta u bol'nykh khronicheskim bronkhitom.

The importance of identification of secretory antiviral antibodies for immunodiagnosis of viral infection in patients with chronic bronchitis was shown. A considerable decrease in the concentration of a secretory form of IgA was noted in patients with chronic bronchitis.

[Immunoreactivity in acute bronchitis]. / Immunoreaktivnost' pri ostrom bronkhite.

In 20 patients with acute bronchitis (AB) the results of the investigations of cellular and humoral immunity and the phagocytic system were compared with a clinical and bronchoscopic picture of disease. The acute period of disease was characterized by considerable activation of the majority of immunoreactivity indices. Complete normalization of the immune status and clinical findings was observed only 3-4 mos after recovery.
