- Abstract
To study the effects of betulin (BE) on myocardial ischemia–reperfusion (I/R) injury in rats, electrocardiogram (ECG) was detected by an electrocardiograph; myocardial infarction was evaluated by triphenyltetrazolium (TTC) staining, serum biochemical indicators myocardial enzymes creatine kinase (CK), lactate dehydrogenase (LDH), aspartate aminotransferase (AST), serum superoxide dismutase (SOD), glutathione (GSH), nitric oxide (NO), and malondialdehyde (MDA); and inflammatory cytokines were tested by using commercial kits. The expression of the Siti1/NLRP3/NF-κB signaling pathway was detected by western blotting and immunohistochemistry experiments. BE improved ECG; reduced myocardial infarction area; decreased CK, LDH, AST, MDA, NO, and inflammatory cytokines; and increased SOD and GSH in I/R rats. In addition, BE also increased Siti1 and decreased the NLRP3/NF-κB signaling pathway in I/R rats. This study shows that the protection of BE is associated with changes in the Siti1/NLRP3/NF-κB pathway.
