Fig. 6From: Exogenous H2S contributes to recovery of ischemic post-conditioning-induced cardioprotection by decrease of ROS level via down-regulation of NF-κB and JAK2-STAT3 pathways in the aging cardiomyocytesThe effect of exogenous H2S on ROS levels. DCFH-DA staining followed by photofluorography was carried out to observe intracellular ROS levels. Quantitative analysis of the mean fluorescence intensity (MFI) of DCFH-DA with Image-Pro Plus software. Mean ± SEM, n = 4. *p < 0.05 vs. control group; #p < 0.05 vs. H/R group; &p < 0.05 vs. PC group; $p < 0.05 vs. H/R + NaHS groupBack to article page
