[Primary research of anti-influenza virus activity of "Benovoair Concentrate"].
OBJECTIVE
Anti-influenza virus activity of "Benovoair Concentrate".


METHODS
The different dilution of samples were mixed with the same quantity of 100 TCID50 virus at 37 degrees C for 30 minutes. Add suitable quantity mixture in wells containing cells. Every 3 wells were the same mode. Viruses control, cells control and samples control of different dilution were performed and set in the CO2 incubator at 37 degrees C. CPE was observed every day. When CPE appears in viruses control as "++++", stopped testing and performed the hemagglutination titration.


RESULTS
"Benovoair Concentrate" with dilution of 1:60, 1:120, 1:240 and 1:480 have 100% anti-influenza A and anti-influenza B activities. "Benovoair Concentrate" with dilution of 1:960 and 1:1920 have 25%-50% anti-influenza A and anti-influenza B activities.


CONCLUSIONS
The test was the proof of anti-influenza virus activities which provided for the development of "Benovoair Concentrate".
