Ischemic stroke results in brain damage and behavioral deficits including memory impairment. Protective effects of green tea extract (GTex) and its major functional polyphenol (-)-epigallocatechin gallate (EGCG) on memory were examined in cerebral ischemic rats. GTex and EGCG were administered 1 hr before middle cerebral artery ligation in rats. GTex, EGCG,(More)
The study was conducted to investigate the ameliorating effects of luteolin on memory acquisition in rats. The effects of luteolin on scopolamine-induced impairment of passive avoidance response were evaluated primarily, as well as the role of the central nervous system through the use of central neurotoxins and central nervous antagonists. Luteolin was not(More)
The aim of this study was to assess the anxiolytic effect of berberine (abbrev. BER) using two experimental anxiety models in the mouse. In the black and white test of anxiety, berberine (100, 500 mg/kg) produced an increase in the first time entry, time spent in the white section, and total changes between two compartments. On the other hand, in the(More)
The present study investigated the effects of luteolin on Abeta (1-40)-induced impairment of Morris water maze (MWM) spatial performance, reference memory, and passive avoidance (PA) behavior in rats. Luteolin treatment was started 4 days before the initiation of behavioral testing (passive avoidance on treatment day of 4-5; MWM spatial performance memory(More)
Puerarin at 10-50 mg/kg attenuated the mecamylamine- but not scopolamine-induced acquisition impairment of inhibitory avoidance performance in an inverse U-shape manner. p-Chloroamphetamine- and dizocilpine-induced acquisition impairment were reversed by puerarin at 25-50 mg/kg. Both piracetam, and tacrine attenuated impairment of inhibitory avoidance(More)
Gallic acid (GA), a naturally abundant plant phenolic compound in vegetables and fruits, has been shown to have potent anti-oxidative and anti-obesity activity. However, the effects of GA on nonalcoholic fatty liver disease (NAFLD) are poorly understood. In this study, we investigated the beneficial effects of GA administration on nutritional(More)
AIM Our previous study indicated petroleum ether layer of Cnidium monnieri L. Cuss. (CM) and its ingredient osthole could alleviate scopolamine-induced amnesia in female rats. MATERIALS AND METHODS Hence, this study was desired to investigate the mechanism of the ameliorating effects of petroleum ether layer of CM on the performance impairment of(More)
This study investigated the antidepressant activity of ethanolic extract of U. lanosa Wallich var. appendiculata Ridsd (UL(EtOH)) for two-weeks administrations by using FST and TST on mice. In order to understand the probable mechanism of antidepressant-like activity of UL(EtOH) in FST and TST, the researchers measured the levels of monoamines and monoamine(More)
Glutamate-induced excitotoxicity has been implicated in a variety of neuronal degenerative disorders. In the present study, we investigated the possible neuroprotective effects of schizandrin against apoptosis of primary cultured rat cortical cells induced by glutamate. Glutamate (10 μM) administered for 24 h decreased the expression of Bcl-2 and Bcl-X(L)(More)
The ameliorating effects of aqueous and ethanolic extracts of LiuWei Dihuang Wang (LDW(W) and LDW(E)) after single, 1-week or 2-week consecutive treatment on the cycloheximide-induced amnesia by using the passive avoidance task in rats were studied. After single treatment, LDW(W) and LDW(E) (1 and 2g/kg) significantly prolonged the shortened step-through(More)
