CAT and brain ischemia: β-Asarone reduces the risk of localized cerebral ischemia-reperfusion injury and improves neurological function by enhancing the activity of enzymes involved in oxidative stress regulation, including lactate dehydrogenase (LDH), glutathione reductase (GR), catalase (CAT), glutathione S-transferase (GST), glutathione (GSH), glutathione peroxidase (GPx), and Na+-K+-ATPase (Yang et al., 2013).
