The state of upper respiratory tract, non-specific cell resistance and immune status were studied in persons who participated in liquidation of the Chernobyl APS disaster consequences. The prolonged influence of factors caused by small doses of ionizing irradiation leads to mucosa affection of upper respiratory tract, considerable reduction of phagocytic and antiviral activity of monocytes and worsening of the immune status of organism. The data obtained during researches explains the considerable increase of ARD among these persons.

[Monocyte functional activity and nonspecific antiviral cellular resistance in a group at high risk for developing acute pneumonia]. / Funktsional'naia aktivnost' monotsitov i nespetsificheskaia protivovirusnaia kletochnaia rezistentnost' v gruppe povyshennogo riska razvitiia ostroi pnevmonii.

Overall 132 patients at greater risk for pneumonia were examined for functional activity of monocytes and antiviral cellular resistance according to the status of intracellular viremia in monocytes and lymphocytes. The control group included 46 healthy men. Proneness to pneumonia was discovered to be related to abnormal function of mononuclear phagocytes and a decrease of antiviral cellular resistance. The conclusion is made about the necessity of the control over functional activity of monocytes, viremia in immunocompetent cells and advisability of carrying out immunomodulatory and antiviral therapy.
