Fig. 2From: Effect of total flavonoids of Spatholobus suberectus Dunn on PCV2 induced oxidative stress in RAW264.7 cellsEffect of TFSD on NO secretion (a) and ROS production (b) in PCV2 infected RAW264.7 cells. Data are presented as mean ± S.D. Bars with different letters are statistically different (P < 0.05). Control: cells without PCV2 infection and drug treatment; PCV2: cells infected with 102.7 TCID50 PCV2; PCV2 + Vc: cells treated with 100 μg/mL of vitamin C after PCV2 infection; PCV2 + TFSD25–100: cells treated with TFSD at concentrations of 25, 50 or 100 μg/mL after PCV2 infection, respectivelyBack to article page
