ETHNOPHARMACOLOGICAL RELEVANCE The root of Scutellaria baicalensis Georgi has been used extensively in traditional Chinese medicine for the treatment of inflammation, fever, cough, dysentery, and hypertension. Baicalein is a flavonoid isolated from the root of Scutellaria baicalensis Georgi and is a novel neuroprotective agent under development for the(More)
RATIONALE Vascular smooth muscle cell (VSMC) proliferation and migration are crucial events involved in the pathophysiology of vascular diseases. Sirtuin 1 (SIRT1), a class III histone deacetylase (HDAC), has been reported to have the function of antiatherosclerosis, but its role in neointima formation remains unknown. OBJECTIVE The present study was(More)
A small portion of the oxygen consumed by aerobic cells is converted to superoxide anion at the level of the mitochondrial respiratory chain. If produced in excess, this harmful radical is considered to impair cellular structures and functions. Damage at the level of mitochondria have been reported after ischemia and reperfusion of organs. However, the(More)
Baicalein, a flavonoid originally isolated from the root of Scutellaria baicalensis Georgi, has numerous pharmacological activities. Up to now, several studies regarding the pharmacokinetic profiles of baicalein have been described, while there is no such study reported in monkey, the species which is more similar to human. The purpose of this study was to(More)
This study was conducted to observe the effect of salvianolic acids (SA) on regional cerebral blood flow (rCBF) in rats and on platelet aggregation in vitro and in vivo. Cerebral ischemia was produced in rats by occluding of the right middle cerebral artery, together with the right common carotid artery. rCBF was monitored by H2 clearance method with a(More)
The present study was designed to evaluate the cardioprotective potential of salvianolic acid A on isoproterenol-induced myocardial infarction in rats. Hemodynamic parameters and lead II electrocardiograph were monitored and recorded continuously. Cardiac marker enzymes and antioxidative parameters in serum and heart tissues were measured. Assay for(More)
Apigenin, one of the most common flavonoids, has demonstrated anti-inflammatory, anticarcinogenic, and free radical-scavenging activities. Recent studies revealed its protective effects against amyloid-β (Aβ)-induced neurotoxicity, but the mechanism was unclear. In the present study, we aimed to explore the anti-amnesic and protective effects of apigenin(More)
Luteolin, a 3',4',5,7-tetrahydroxyflavone, is a plant flavonoid and pharmacologically active agent that has been isolated from several plant species. In the present study, the effects of luteolin obtained from the medicinal plant Elsholtzia rugulosa and the related mechanisms were examined in an Alzheimer's disease (AD) cell model. In this model, copper was(More)
ELSHOLTZIA RUGULOSA (Lamiaceae), a common Chinese herb, is widely used in the treatment of cold and fever. In order to elucidate the action mechanism and the active principles from the plant against anti-influenza virus, the influenza virus neuraminidase (NA) activity assay and IN VITRO antiviral activity assay were established, and the isolation of the(More)
Background: It is known that amyloid-b peptide (Ab) plays a pivotal role in the pathogenesis of Alzheimer’s disease (AD). Interaction between Ab and the receptor for advanced glycation end products (RAGE) has been implicated in neuronal degeneration associated with this disease. Pinocembrin, a flavonoid abundant in propolis, has been reported to possess(More)
