However, treatment with bacterial extract (200 mg/kg/day, IP), GNPs (200 mg/kg/day, IP), and BE and GNPs in combination, respectively, for 14 successive days in rats with isoproterenol-induced myocardial infarction resulted in a significant increase in the activity of antioxidant enzymes GRx, and SOD when compared to ISO-treatment alone (p < 0.05), Figure 10. Here, SOD1 is linked to myocardial infarction.
