Baicalein (BA), a plant-derived active flavonoid present in the root of Scutellaria baicalensis, has been widely used for the treatment of stress-related neuropsychiatric disorders including depression. Previous studies have demonstrated that repeated restraint stress disrupts the activity of the hypothalamic-pituitary-adrenal (HPA) axis, resulting in(More)
The purpose of this study was to examine whether acupuncture improves spatial cognitive impairment induced by repeated corticosterone (CORT) administration in rats. The effect of acupuncture on the acetylcholinergic system was also investigated in the hippocampus. Male rats were subcutaneously injected with CORT (5 mg/kg) once daily for 21 days. Acupuncture(More)
Many studies have shown that Bupleurum falcatum (BF), which is widely used in the treatment of various psychosomatic diseases in traditional Oriental medicine, is an effective therapeutic intervention for memory impairment. The purpose of this study was to examine the effect of BF on stress-induced alterations in learning and memory in rats using the Morris(More)
The purpose of this study was to evaluate whether berberine (BER) administration could attenuate depression- and anxiety-like behaviors and increase corticotrophin-releasing factor (CRF) and tyrosine hydroxylase (TH) expression following chronic morphine withdrawal in rats. Male rats were exposed to chronic, intermittent, escalating morphine (10~50 mg/kg)(More)
Repeated injection of corticosterone (CORT) induces dysregulation in the HPA axis, resulting in depression and anxiety. Many studies have shown that acupuncture, which is widely used for the treatment of stress and mental illness, in East Asian countries, is an effective therapeutic intervention for psychosomatic disorders. We investigated the influence of(More)
In traditional Oriental medicine, some herbal combinations that include Bupleurum falcatum (BFM) as a major ingredient are known to effectively treat depressive-like disorders. In the present study, the antidepressant-like effect of methanolic extract of BFM and its neuropharmacological mechanism were investigated in mice. After oral administration of BFM(More)
BACKGROUND Acupuncture is an alternative therapy that is widely used to treat various neurodegenerative diseases and effectively improve cognitive and memory impairment. The aim of this study was to examine whether acupuncture stimulation at the Baihui (GV20) acupoint improves memory defects caused by scopolamine (SCO) administration in rats. We also(More)
The purpose of this study was to examine whether baicalin (BAI) improves spatial cognitive impairments induced in rats following the repeated administration of the exogenous stress hormone corticosterone (CORT). The effect of BAI on the hippocampal expression of brain-derived neurotrophic factor (BDNF) and cAMP response element-binding protein (CREB) was(More)
The ameliorating effect of phosphatidylserine (PS) isolated from krill (KR-PS) on the learning and memory deficits associated with normal aging in rats was investigated, as compared with soybean PS (SOY-PS). Rats were orally administered with KR-PS (20, 50 mg kg-1) and SOY-PS (50 mg kg-1) daily, for 7 days, 30 min before behavioral assessment using the(More)
OBJECTIVES The ameliorating effects of wild ginseng on learning and memory deficits were investigated in rats. METHODS Rats were treated daily with wild ginseng or cultivated ginseng for 7 days at 30 min before scopolamine injection (2 mg/kg, i.p.). After inducing cognitive impairment by the administration of scopolamine, behavioural assessment using the(More)
