Mechanism study of anti-influenza effects of Radix Isatidis water extract by red blood cells capillary electrophoresis

<p><b>OBJECTIVE</b>To research the mechanism of the inhibition effects of BWE on cell attachment of influenza virus by capillary electrophoresis.</p><p><b>METHOD</b>The morphologic difference of red cells after treating with BWE infected by influenza virus was detected with microscope, capillary electrophoresis and HA.</p><p><b>RESULT</b>The pretreatment of the normal cells with BWE inhibited the attachment of influenza to the cells, while no meaningful inhibition was observed when influenza virus was pretreated before being inoculated to cells.</p><p><b>CONCLUSION</b>The results indicate that the inhibition effects of BWE on cell attachment of influenza virus may be an important mechanism of anti-influenza activity of Radix Isatidis Extracts.</p>
