Objective: This experiment was designed to investigate the effect of the KSKH hot water extract & ultra-fine powder on microglia and memory deficit model. Method: The effects of the KSKH hot water extract on expression of IL-1$\beta$, IL-6, TNF-$\alpha$ mRNA and production of IL-1$\beta$, IL-6, TNF-$\alpha$ in BV2 microglial cell line treated by lipopolysacchaide(LPS) were investigated. The effects of the KSKH hot water extract & ultra-fine-fine powder on the behavior of the memory deficit mice induced by scopolamine and AChE in serum of the memory deficit mice induced by scopolamine were investigated. Results: 1. The KSKH hot water extract suppressed the expression of IL-1$\beta$, IL-6, TNF-$\alpha$ mRNA in BV2 microglial cell line treated by LPS. 2. The KSKH hot water extract suppressed the production of IL-1$\beta$, IL-6, TNF-$\alpha$ in 100$\mu g/m\ell$ concentration of BV2 microglial cell line culture supernatant. 3. The KSKH hot water extract & ultra-fine powder decreased AChE activation significantly in the serum of the memory deficit mice induced by scopolamine. 4. The KSKH hot water extract & ultra-fine powder showed significant effect on memory impairment in the stop-through latency type of Morris water maze test. Conclusions: This experiment shows that the KSKH hot water extract & ultra-fine powder might be effective for the prevention and treatment of amnesia and Alzheimer's disease. Investigation into the clinical use of the KSKH hot water extract & ultra-fine powder for amnesia and Alzheimer's disease is suggested for future research.

This study was aimed to investigate the memory enhancing effect of Jeongjihwan against scopolamine-induced amnesia in C57BL/6 mice. To determine the effect of Jeongjihwan on the memory and cognitive function, we have injected scopolamine (1 mg/kg, i.p.) into C57BL/6 mice 30 min before beginning of behavior tests. We have conducted Y-maze, Morris water-maze, passive avoidance and fear conditioning tests to compare learning and memory functions. Scopolamine-induced behavior changes of memory impairment were significantly restored by oral administration of Jeongjihwan (100 or 200 mg/kg/day). To elucidate the molecular mechanism underlying the memory enhancing effect of Jeongjihwan, we have examined the antioxidant defense system and neurotrophic factors. Jeongjihwan treatment attenuated intracellular accumulation of reactive oxygen species and up-regulated mRNA and protein expression of antioxidant enzymes as assessed by RT-PCR and western blot analysis, respectively. Jeongjihwan also increased protein levels of brain-derived neurotrophic factor (BDNF) compared with those in the scopolamine-treated group. Furthermore, as an upstream regulator, the activation of cAMP response element-binding protein (CREB) via phosphorylation was assessed by Western blot analysis. Jeongjihwan elevated the phosphorylation of CREB (p-CREB), which seemed to be mediated partly by extracellular signal-regulated kinase1/2 (ERK1/2) and protein kinase B/Akt. These findings suggest that Jeongjihwan may have preventive and therapeutic potential in the management of amnesia.

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.

Alzheimer's disease(AD) is a progressive neurodegenerative disease, which is pathologically characterized by neuritic plaques and neurofibrillary tangles associated with the acetylcholinesterase, apolipoprotein E and butylcholinesterase, and by mutations in the presenilin genes PS1 and PS2, and amyloid precursor proteins (APPs) overexpression. The present research is to examine the inhibitory effect of KGBH on PS1, PS2 and APPs overexpression detected by Western blotting. To verify the Effects of KGBH on cognitive deficits further, we tested it on the scopolamine(1mg/kg)-induced amnesia model of the mice using the Morris water maze tests, and there were ameliorative effects on memory impairment as a protection against scopolamine. KGBH only partially blocked the increase in blood serum level of acetylcholinesterase and Uric acid induced by scopolamine, where as blood glucose level was shown to attenuate the amnesia induced by scopolamine and inreased extracellular serum level. In conclusion, studies of KGBH that has been known as anti-choline and inhibitory ablilities of APPs overexpression, could also be used further as a important research data for a preventive and promising symptomatic treatment for Alzheimer's disease.

In this study, I investigated physiology and pathology of the kidney and then researched deficiency of the kidney-nourishing the Eum music therapy to apply for clinical use, because symptoms such as chronic fatigue, morbus asthenia, anxiety, dizziness, tinnitus, and amnesia are prevalent in our modern societies. These symptoms are due to deficiency of the kidney. The kidney stores vital essence and has a function to keep activities as motive power. If the kidney is abnormal in storing the essence and holding Gi, various symptoms like dizziness, tinnitus, amnesia are caused by deficiency of the kidney. In deficiency of the kidney-nourishing the Eum music therapy, Water-Gi music which can store the essence is mainly used. In case of patients with deficiency of the kidney, dizziness, tinnitus, and amnesia, we can make use of NO.3, BWV 1068, Air of J.S.Bach and Jinyangjo of Geomungo. If there are flaring-up and fidgetiness due to deficiency of vital essence, Earth-Gi music that can help the vigor of spleen and stomach should be used prior to Water-Gi music. In the concrete, Hahyeondodeuri of Yeongsanhoesang played on Geomungo can be used. The tinnitus is caused by wind-heat and fire in the gallbladder. It is good to nourish the Eum through Water-Gi music after dispelling pathogens through Jajinmori among Gayageum sanjo.
