The present study examined the effects of Tremella fuciformis (TF) on the learning and memory function and the neural activity in rats with trimethyltin (TMT)-induced memory deficits. The rats were administered saline or TF (TF 25, 50, 100 mg/kg, p.o.) daily for 21 days. The cognitive improving efficacy of TF on the amnesic rats, which was induced by TMT,(More)
Black ginseng (BG) has been widely used as herbal treatment for improving physiological function. In order to investigate the neuroprotective action of this herbal medicine, we examined the influence of BG on the learning and memory of rats using the Morris water maze, and we studied the effects of BG on the central cholinergic system and neural nitric(More)
In order to the neuroprotective effect of Lycium chinense fruit (LCF), the present study examined the effects of Lycium chinense fruit on learning and memory in Morris water maze task and the choline acetyltransferase (ChAT) and cyclic adenosine monophosphate (cAMP) of rats with trimethyltin (TMT)-induced neuronal and cognitive impairments. The rats were(More)
The present study examined the effects of squid phosphatidylserine (Squid-PS) on the learning and memory function and the neural activity in rats with TMT-induced memory deficits. The rats were administered saline or squid derived Squid-PS (Squid-PS 50 mg kg(-1), p.o.) daily for 21 days. The cognitive improving efficacy of Squid-PS on the amnesic rats,(More)

Meyer) on the learning and memory function and the neural activity in rats with trimethyltin (TMT)-induced memory deficits. The rats were administered with saline or WG (WG 100 or 300 ㎎/㎏, p.o.) daily for 21 days. The cognitive improving efficacy of WG on the amnesic(More)
BACKGROUND Psychological stressors may cause affective disorders, such as depression and anxiety, by altering expressions of corticotropin releasing factor (CRF), serotonin (5-HT), and tyrosine hydroxylase (TH) in the brain. This study investigated the effects of essential oil from Asarum heterotropoides (EOAH) on depression-like behaviors and brain(More)
Cancer related fatigue (CRF) is one of the most common side effects of cancer and its treatments. A large proportion of cancer patients experience cancer-related physical and central fatigue so new strategies are needed for treatment and improved survival of these patients. BST204 was prepared by incubating crude ginseng extract with(More)
OBJECTIVE Phosphatidylserine, a major acidic phospholipid in the brain, has been studied extensively in regard to its actions on brain functions. The present study examined the effects of Krill phosphatidylserine (Krill-PS) on the learning and memory function and the neural activity in the normal young rats. METHODS The rats were administered saline or(More)
