[EFFECTIVENESS OF FULLERENE-(TRIS-AMINOCAPRONIC ACID) HYDRATE IN THE MODEL OF EXPERIMENTAL VIRAL-BACTERIAL PNEUMONIA OF MICE].

ABSTRACT

AIM: Study the effectiveness of the substance and various drug formulations of fullerene-(tris-aminocapronic acid) hydrate (FTAAH onwards) in the model of experimental viral-bacterial pneumonia of mice. MATERIALS AND METHODS: BALB/c mice were infected with influenza virus A/California/04/2009 and subsequently infected with Staphylococcus aureus. The animals were treated after viral infection with the substance and various drug forms of FTAAH, as well as comparative preparations--oseltamivir and arbidol. Therapy effectiveness was evaluated by clinical indicators (survival, lifespan, animal mass decrease reduction), virological (virus titer), microbiological (density of bacteria in lungs) parameters, confirmed by pathomorphological characteristics of lungs. RESULTS: FTAAH therapy in injectable form was effective in the model of a combined viral-bacterial pneumonia of mice by all the studied criteria treatment increased mice survival, reduced the decrease of their body weight, resulted in a reduction of virus titers and density of bacteria in lungs, that correlated with the data from morphological study and signs of bronchopneumonia resolution in mice. FTAAH therapy in rectal form depended on animal infection schemes, as well as preparation dose, increasing with its increase. CONCLUSION: FTAAH substance is effective in the model of experimental viral-bacterial pneumonia of mice.
