Both Moutan cortex of Paeonia suffruticosa Andrews (MC) and the root of Paeonia lactiflora Pall (PL) are important Traditional Chinese herbs used commonly to treat inflammatory and pyretic disorders. Paeonol, a common component of MC causes anti-platelet aggregation and scavenges free radicals. Therefore, the aim of the present study is to investigate the effects of Paeonol on cerebral infarct. A total of 60 male Sprague-Dawley (SD) rats were studied. An animal model of cerebral infarct was established by occluding both common carotid arteries and the right middle cerebral artery for 90 min, followed by a 24 h period of reperfusion. The percentage of cerebral infarction area to total brain area in each piece of brain tissue, and neuro-deficit score were measured. Superoxide anion was determined by the number of lucigenin-chemiluminescence (CL) counts. ED1 (mouse anti rat CD68) and interleukin-1beta (IL-1beta) immunostaining in the cerebral infarction region were also investigated for activation of microglia. The results indicated that Paeonol 15 and 20 mg/kg pretreatment and 20 mg posttreatment reduced the cerebral infarction area; Paeonol 15 and 20 mg/kg pretreatment reduced the neuro-deficit score. In addition, Paeonol 20 mg/kg pretreatment reduced the lucigenin-CL counts at 2 h period of reperfusion. The number of ED1 and IL-1beta immunoreactive cells also reduced in the cerebral infarction region; there were no significant changes in blood sugar levels. The results show that Paeonol reduced cerebral infarct and neuro-deficit in rat, suggesting Paeonol might play a similar role in reducing cerebral infarction in humans. Paeonol suppresses and scavenges superoxide anion, and inhibit microglia activation and IL-1beta in ischemia-reperfusion injured rats.
