ROS overproduction and MMP dissipation induced by H3N2 were inhibited by RH. (A) (a) ROS expression was detected via DCFH fluorescence intensity. Scale bar = 100 μm. (b) The levels of ROS were analyzed using ImageJ. (B) (a) MMP expression was detected via JC-1 polymer fluorescence intensity. Scale bar = 20 μm. (b) JC-1 polymer levels were analyzed using ImageJ. Results of three separate trials were given as the mean ± SD. **P < 0.01, ***P < 0.001 vs. the H3N2 group.
