Excessive ROS scavenging effect of PCA in HDF cells. Effect of PCA on excessive-generated intracellular ROS scavenging capacity was determined by DCF-DA fluorescent intensity. HDF cells had been treated with LPS (1 μg/mL) and PCA for 24 h and then were reacted with DCFH-DA (25 μM). Data are expressed as mean ± standard deviation of triplicate experiments (*p < 0.05)
