Abstract
This study aimed to evaluate the cardioprotective effects and mechanism of scutellarin (Scu) on heart ischaemia/reperfusion (I/R) injury by using an isolated Langendorff rat heart model. Myocardial function was evaluated via measurements of cardiac haemodynamic parameters. Myocardial infarct size was macroscopically estimated by using TTC staining. The release of creatine kinase (CK) and lactate dehydrogenase (LDH) was used to evaluate cardiac injury. GSH/GSSG, SOD, and MDA were determined as being indicators of oxidative stress. CRP, IL-6, and TNF-α were also analysed to assess inflammation in the heart tissues. Cardiomyocyte apoptosis was quantified by using a TUNEL kit. PPARγ, Nrf2, and NF-κB were assayed via Western blotting. The results indicated that I/R induced significant cardiac dysfunction, myocardial infarct, and apoptosis, as well as decreasing the GSH/GSSG ratio, SOD activity, Nrf2 protein expression, and PPARγ protein expression, but increased levels of TNF-α, MDA, CRP, IL-6, and NF-κB. These data suggest that Scu attenuates cardiac I/R.
