The purpose of the present study was to examine the protective action and mechanisms of pinocembrin (1) on the neurovascular unit (NVU) in permanent cerebral ischemic rats. Focal cerebral ischemia was induced by occlusion of middle cerebral artery (MCAO) in rats. Compound 1 (3, 10, or 30 mg/kg) was
The aim of this study was to investigate the effects of pinocembrin on brain ischemia/reperfusion (I/R) injury and the potential involvement of autophagy activity changes in the penumbra area in the mechanisms of pinocembrin activity. Focal cerebral I/R model was induced by middle cerebral artery
Tissue-type plasminogen activator (t-PA) remains the only approved therapy for acute ischemic stroke but has a restrictive treatment time window of 4.5 hr. Prolonged ischemia causes blood-brain barrier (BBB) damage and increases the incidence of hemorrhagic transformation (HT) secondary to
OBJECTIVE
The therapeutic effect of pinocembrin, together with the therapeutic time window, in the transient global cerebral ischemia/reperfusion (I/R) rats was investigated.
METHODS
Adult male Sprague-Dawley rats were subjected to global cerebral ischemia for 20 min by four-vessel occlusion.
Blood-brain barrier (BBB) disruption is a major consequence of cerebral ischemia/reperfusion. Several studies have reported the neuroprotection of pinocembrin on cerebral ischemia in vivo and in vitro, but the effects of pinocembrin on BBB and its underlying mechanisms are not clear. In this study,
Pinocembrin or 5, 7-dihydroxyflavanone is a flavanone, a type of flavonoid. In the present study, we first assessed the anti-inflammatory effects of pinocembrin in RAW macrophage cells; and based on these effects, we investigated the therapeutic effects of pinocembrin in murine model of
The cyclohexenyl chalcone derivative [(-)-hydroxypanduratin A], together with the previously known panduratin A, sakuranetin, pinostrobin, pinocembrin, and dihydro-5,6-dehydrokawain were isolated from the chloroform extract of the red rhizome variety of Boesenbergia pandurata (Robx.) Schltr.
The propolis produced by bees are used in alternative medicine for treating inflammation, and infections, presumably due to its antioxidant properties. In this context, five propolis from México were investigated to determine their inhibitory lipid peroxidation properties. The ethyl acetate extract
This study was designed to investigate whether functional and molecular MRI techniques are sensitive biomarkers for assessment of neuroinflammation and drug efficacy after traumatic brain injury (TBI) in rats. We subjected rats to a controlled cortical impact model and used behavioral tests,
Propolis is a resinous substance produced by bees and known to possess antioxidant, antimicrobial, antiproliferative and anti-inflammatory activities.This study is aimed at evaluating the in vivo and in vitro anti-inflammatory potential of the Crude
