Effects of antioxidants in scavenging the DPPH radicals and ROS generation in the OA-treated cells. DPPH radical scavenging effect (%) of each antioxidant was compared by percentages based on the control level (A). The ROS level produced after treatment with antioxidant in OA-treated cells was determined using DCF-DA staining (B). DCF-DA-stained cell images (C). Data are represented as mean ± SD values (n = 4). Asterisk (*) indicates a significant difference compared with the control (p < 0.05). Sharp (#) indicates a significant difference among the experimental groups (p < 0.05).
