Vinegar/Tetramethylpyrazine Induces Nutritional Preconditioning Protecting the Myocardium Mediated by VDAC1

Table 2

Vinegar/TMP preconditioning preserves the myocardial homogenate ferric reducing antioxidant potentiality and the activities of antioxidant enzymes and reduced the levels of lipid peroxidation in the myocardium against A/R injury.
