[Impairment of antiviral cellular resistance and possibilities of its correction during acute altitude hypoxia].

Antiviral cell resistance of blood monocytes and lymphocytes was studied in 29 healthy human subjects subjected to acute altitude hypoxia (AAH) in climatic chamber TABAI, and 39 healthy males during rapid ascent from the sea level up to 3250 m. The antiviral resistance of immune cells was found to be suppressed by AAH. Double blind method was used to compare effects of placebo, dexamethasone and olifen (approved by the Pharmacology Committee of the Russian Ministry of Health as an antihypoxic preparation) on the antiviral resistance of cells during AAH.
