Objectives : Amnesia is theloss or impairment of memory, caused by physical injury, disease, drugs, or emotional trauma. Recently, the average life span is increasing, while at the same time, the incidence of dementia-like diseases in conjunction with amnesia are also increasing. Therefore learning and memory are very important issues in modern society. Ancient Korean physicians used several herbs to treat dementia and these herbal effects were described in Korean herbal books. Among them are some reports on several cognitive-enhancing herbs which have since been shown to improve dementia in recent pharmacological studies, such as Panax ginseng; however, the facilitatory effects of many Korean cognitive-enhancing herbs on learning and memory are limited. Learning and memory are essential requirements for every living organism in order to cope with environmental demands; cholinergic systems are known to be involved in learning and memory. Methods : In this study, the effects of Acori graminei rhizoma (AGR, 石菖蒲) on learning and memory were investigated by Morris water maze, eight-arm radial maze, and the effects on the central cholinergic system of rats injected with scopolamine. Results : In the water maze, the experimental animals were trained to find a platform in a fixed position for 6 days and then received a 60 sec probe trial in which the platform was removed from the pool on the 7th day. In the eight-arm radial maze, the animals were tested four times per day for 6 days. Scopolamine impaired performance of the maze tests and reduced activity of acetylcholinesterase (AchE) in the hippocampus, which is a marker for the central cholinergic system. There were significant reversals from the scopolamine-induced deficits on learning and memory in these tests, through daily administrations of AGR (100 mg/kg, p.o.) over 14 consecutive days. These treatments also reduced the loss of cholinergic activity in the hippocampus induced by scopolamine. Conclusions : These results demonstrated that AGR ameliorated learning and memory deficits by affecting the central acetylcholine system.

Belamcandae Rhizoma (BR), the rhizome of Belamcanda chinensis (L.) DC., possesses various biological properties such as anti-inflammatory activity, antioxidant activity and antimutagenic activity. However, there have been no studies on the anti-amnesic effect of BR. In this study, we assessed the improvement effect of BR extract on scopolamine-induced amnesia in mice. ICR mice were administrated with BR (50, 100 or 200 mg/kg, p.o.) and were subsequently injected of scopolamine (1 mg/kg, i.p.) 30 min before behavioral tasks (Y-maze, passive avoidance and Morris water maze tasks). To further assess the possible mechanisms of BR, the ex vivo acetylcholinesterase (AChE) activity was also evaluated. BR could ameliorate scopolamine-induced memory impairment and could regulate the cholinergic function by inhibiting the AChE activity. These data demonstrated that BR exert candidate extract against amnesia by restoring the cholinergic activity.
