Objectives : This study investigated the protective effects of the water extracts of Chongmyung-tang, Polygalae Radix, and Acori Graminei Rhizoma in an in vivo Alzheimer's disease (AD) mouse model. Methods : Memory impairment was induced by an intraventricular injection of $A{\beta}25-35$ peptides and subsequently Chongmyung-tang, Polygalae Radix, or Acori Graminei Rhizoma extract were administered orally for 14days. Results : In the water maze task, Chongmyung-tang, Polygalae Radix, and Acori Graminei Rhizoma extracts improved learning ability during the acquisition period and significantly increased memory scores during the retention period versus $A{\beta}-injected$ controls. Furthermore, the toxicity of $A{\beta}25-35$ on hippocampus was assessed immunohistochemically (Tau, MAP2, TUNEL, Bax) and by in vitro study. Chongmyung-tang, Polygalae Radix, and Acori Graminei Rhizoma demonstrated significant neuroprotective effects against oxidative damage and apoptotic cell death of hippocampal neurons damaged by $A{\beta}25-35$. Conclusions : These results suggested that Chongmyung-tang, Polygalae Radix and Acori Graminei Rhizoma extract improve memory impairment and reduce Alzheimer's dementia via anti-apoptotic effects and by modulating the expressions of Tau and MAP2 protein in the hippocampus.

The purpose of this study was to introduce the differential standard of the types of Acori Graminei Rhizoma. We established the classificatory standard according to the external and internal morphology for the several types of Acori Graminei Rhizoma. 1. External shape: Acorus gramineus has smaller size and fibroidal section. A. calamus has bigger size and cancellate section. A. tatarinowii has middle size and fibroidal section. Anemone altaica has very small long-spindle shape and flat section that has 6-12 row of vascular bundle. 2. Internal shape: Acorus gramineus has some bundle sheath fiber, but A. calamus has not. A. tatarinowii has many calcium oxalate crystalloid around bundle sheath. Anemone altaica has obscure cambium. All sample except A. altaica, in the mass, has scattered bundle, thin cell wall, broad cortex and well-developed endodermis. For the future, such results will be used as the basic source of additional research, and a far-reaching comparative study is needed to distinguish between many kinds of same genus-degree of relatedness.

Induction of phase II enzymes such as quinone reductase (QR) and glutathione S-transferase (GST) is considered a major mechanism of protection against initiation of carcinogenesis. The present study was performed to evaluate the chemopreventive activity of Acori Graminei Rhizoma aqua-acupuncture solution (AGRAS) and Acori Graminei Rhizoma water-extracted solution (AGRWS) by measuring the induction of phase II enzymes. AGRAS and AGRWS are potent inducers of quinone reductase activity in murine hepatoma Hepa1c1c7 cells. The levels of GSH and GST was increased sightly with AGRAS and AGRWS. These results suggest that AGRAS and AGRWS may act as blocking agents against carcinogenesis by induction of phase II enzymes.

The methanol extracts were prepared from 46 oriental medicines currently used for stroke treatment, and the effects were assessed on the excitotoxic neuronal cell death induced by L-glutamate(Glu) in primary cultured rat cortical neurons. The extracts from Angelicae gigantis Radix, Manitis Squama, Acori graminei Rhizoma, Uncariae Ramulus et Uncus, Alpiniae Fructus, Paeoniae Radix, and Cnidii Rhizoma inhibited the Glu-induced neurotoxicity with the IC$_50$ values of 95.2, 218.6, 263.3, 295.1, 297.9, 310.1, and 446.7 $\mu$g/ m$\ell$, respectively. The extracts from Arisaematis Rhizoma, Loranthi Ramulus, Anemarrhenae Rhizoma, Carthami Flos, Clematidis Radix, Bambusae Concretio Silicea, and Angelicae koreanae Radix also exhibited significant inhibition of the toxicity. In contrast, the extracts from Aconiti Tuber Araliae cordatae Radix, Curcumae Rhizoma, Leonuri Herba, Polygalae Radix, Salviae Radix, and Siegesbeckiae Herba increased the Glu-induced toxicity at the concentrations of 500 and 1000 $\mu$g/m$\ell$. Rest of the extracts evaluated in the present study showed minor or negligible inhibition. liken together the oriental medicines including Angelicae gigantis Radix, Muitis Squama, Acori graminei Rhizoma, Uncariae Ramulus et Uncus, and Alpiniae Fructus appear to exert pharmacological effects through the inhibition of excitotoxic neuronal cell death. Further studies are in progress to characterize active principles in these extracts.

One subfraction from the hexane fraction of Acri graminei Rhizoma, the E4 fraction which is mainly consisted of acorenone, showed a potential inhibitory activity against chloramphenicol acetyltransferase (CAT) of S. aureus SA2 that is a multidrug-resistant strain to 10 usual antibiotics. The combination therapy of this fraction with chloramphenicol resulted in reduction of the minimal inhibitory concentration from 128 $\mu\textrm{g}$/ml to 8 $\mu\textrm{g}$/ml. The E4 fraction also revealed to prevent the induction of CAT from this strain.

Alzheimer's disease(AD) is a geriatric dementia that is widespread in old age. In the future AD will be the largest problem in public health service. From old times, Much medicines have been used for treatment of dementia, but there is no medicine having obvious effect. AD is one of brain retrogression disease. So We studied on herbal medicine that have a relation of brain retrogression. From old times, In Oriental Medicine, Rhizoma Acori Graminei has been used for disease in relation to brain retrogression. We studied on the effects of anti-Alzheimer in pCT105-induced neuroblastoma cell lines by Rhizoma Acori Graminei extract As the result of this study, In RAG group, the apoptosis in the nervous system is inhibited, the repair against the degerneration of Neuroblastoma cells by CT105 expression is promoted. These results indicate that RAG possess strong inhibitory effect of apoptosis in the nervous system and repair effect against the degeneration of Neuroblastoma cells by CT105 expression.

Acori graminei Rhizomn (AGR) is a perennial herb which has been used clinically as a traditional oriental medicine against stroke, Alzheimer's disease, and vascular dementia. We investigated the effect of AGR on the modulation of gene expression profile in a hypoxic model of cultured rat cortical cells. Rat cerebrocortical cells were grown in Neurobasal medium. On DIV12, cells were treated with AGR $(10ug/m\ell)$, given a hypoxic shock (2% $O_2$, 3 hr) on DIV14, and total RNAs were prepared one day after shock. Microarray analyses indicated that the expression levels of most genes were altered within the global M values +0.5 and -0.5, i.e., 40% increase or decrease. There were 750 genes which were upregulated by < global M +0,2, while 700 genes were downregulated by > global M -0.2. The overall profile of gene expression suggests that AGR suppresses apoptosis (upregulation of anti-apopotic genes such as TEGT, TIEG, Dad, p53, and downregulation of pro-apopotic genes such as DAPK, caspase 2, pdcd8), ROS (upregulation of RARa, AhR), and that AGR has neurotrophic effects (upregulation of Aktl, Akt2). These results provide a platform for investigation of the molecular mechanism of the effect of AGR in neuroprotection.
