Fig. 4. Influence of remote ischemic preconditioning (RIPC), hydrogen sulfide (H₂S) donor, H₂S precursor and HIF-1α inhibitor on ischemia-reperfusion-induced changes in the H₂S levels in young and old rat hearts, after 120 min of reperfusion. HIF, hypoxia-inducible factor; NaHS, sodium hydrosulfide; LC, l-cysteine. ^ap < 0.05 vs. normal; ^bp < 0.05 vs. control; ^cp < 0.05 vs. RIPC in young; ^dp < 0.05 vs. RIPC in old; ^ep < 0.05 vs. NaHS (20 µM/kg) and RIPC in old; ^fp < 0.05 vs. LC (20 mg/kg) and RIPC in old.
