Abstract

Abstract:

Objective To investigate the role of dihydromyricetin (DHM) in the treatment of ischemic stroke in rats, and to explore the effect of DHM on the expression of inflammasome. Methods The middle cerebral artery occlusion (MCAO) model was induced by endovascular suture method. The therapeutic effect and mechanism of DHM were investigated by Longa score, TTC staining, Nissl staining, immunohistochemical staining and Western bloting. Results After DHM treatment, the motor capacity of MCAO rats was significantly improved, the infarct volume was significantly reduced, the brain structure and neuron morphology were improved, and the expressions of nod-like receptor protein-3 (NLRP3) and interleukin-1β(IL-1β) decreased significantly. Conclusion DHM can down-regulate the expression of NLRP3 and thus reduces the cerebral infarction volume and improves neurobehavioral performance in MCAO rats.
