Figure 4From: Inhibitory effect of ginsenoside Rg3 combined with gemcitabine on angiogenesis and growth of lung cancer in mice Changes of dynamic parameters of arterial blood flow in tumors by color Doppler flow imaging. PSV: peak systolic velocity; RI: resistive index, RI = PSV-EDV/PSV (EDV: end diastolic velocity). â–«P < 0.05 vs control group; â–¡P < 0.05 vs gemcitabine group; â– P < 0.05 vs ginsenoside Rg3 group.Back to article page
