MPO and cerebral infarction: The results showed that compared with the ischemia/reperfusion group, the LPs can significantly reduce the nervous system score, the cerebral infarction volume, the brain water content, malondialdehyde (MDA) content, myeloperoxidase (MPO) activity, TNF-α and IL-1β levels, Bax expression, and increase superoxide dismutase (SOD), glutathione (GSH), glutathione peroxidase (GSH-Px) activity and expression of Bcl-2.
