Gastrodia elata (GE) is a oriental medicinal herb which has been used traditionally for the treatment of various brain diseases including convulsion and epilepsy. In orde r to examine the mechanism of anticonvulsive effect, we treated the methanol extract of GE (500mg/kg, P.0) to the pentylenetetrazole (PTZ)-induced convulsive rats. Methanol extracts of GE significantly inhibited (35%) the convulsion state as well as the level of lipid peroxidation (25%) in the brain. The ether fraction of methanol extracts among the others effectively ibhibited in vitro lipid peroxidation dose dependently ($5.O{\times}10^{-6}{\sim}2.O{\times}1O^{-5}g/ml$). The scavenging effect on hydroxy radicals was found in all the fractions of ether, butanol, and dichloromethane. These results suggest that the anticonvulsive effect of GE is possibly due to the antioxidative effects of the active components in GE.

Gastrodia elata (GE) is an oriental medicinal herb which has been used traditionally for the treatment of various brain diseases including convulsion and epilepsy. The purpose of this study was to determine pharmacokinetic parameters of 4-hydroxy-3-methoxybenzaldehyde (HMBA) and p-hydroxybenzaldehyde (PHBA), constituents of GE, in rats. Male rats were cannulated in the femoral vein, femoral artery, bile duct and ureter. They received a single i.v. bolus dose of either HMBA or PHBA through the femoral vein. The concentration of HMBA or PHBA in plasma, bile and urine samples were analyzed by reversed-phase HPLC. HMBA and PHBA have very short half-lives, i.e. 4.03 and 2.26 minutes respectively. Most of HMBA and PHBA were thought to be eliminated through metabolism as the metabolized fraction approaches unity. Derivatives of HMBA or PHBA with longer biological half-lives should be designed to develop better anticonvulsants and more complete qualitative and quantitative understanding of the overall pharmacokinetic fate of these compounds awaits further investigation.

Objectives : In Alzheimer's disease(AD), free radical oxidative stress caused by amyloid beta-peptide may lead to DNA damage, neuronal dysfunction, neurotoxicity and cell death, Hwangryunhaedok-tang(HHT) is traditionally used for the treatment of pyrogenetic diseases. To develop a new anti-AD drug from natural herb, HHT was selected and extracted in this study. Methods : The antioxidant activities of HHT water extract powder were examined by hydroxyl radical-induced DNA strand nicking assay, and antioxidative enzymes expression assay in H4IIE cell. In addition, HHT was examined for the inhibitory effect on the acetylcholinesterase(AChE) using by Ellman's coupled assay. Results: The HHT exhibit DNA protective effect in the hydroxyl radical-induced DNA Strand nicking assay, mRNA expression of superoxide dismutase and glutathione peroxidase were recovered at a normal level by HHT treatment in H4IIE cell. Furthermore, water extract of HHT showed inhibitory effect on AChE activity. Conclusion : These results suggest that HHT may be effective in delaying and preventing AD progression related to the free radical-induced DNA damage and AChE activity.

The youngkaechulgamtang (Y) composed of four herb drugs, including Hoelen (H). Cinnamomi Ramulus (C). Atractylodis Rhizoma Alba (A) and Glycyrrhizae Radix (G). In oriental medicine literatures, Youngkaechulgamtang is described to be effective in headache, inflammation, uremia, gastritis, diarrhea and hypertension. To estimate the clinical effectiveness of Youngkaechulgamtang, several pharmacological experiments were carried out. The results are summerized as follows; On acetaminophen-induced hepatotoxicity, C+A, Y-G, Y-H, MIX and Y showed the significant elevation of glutathione-S-transferase. But, C+A, Y-G, Y-H, MIX and Y showed the significant suppression of serum aminotransferases. On ANIT-induced cholestasis, U (Ursodesoxycholic acid 50 mg/kg)+$Y_l$ (760 mg/kg) showed the significant increase of bile juice volume. $Y_l,\;Y_2$ (1520 mg/kg), U, $U+Y_l$ showed the remarkable increase of cholic acid. U and $U+Y_l$ showed the significant decrease of total bilirubin. From these results, it is suggest that Y shows liver protective effect against various hepatic injury. Especially, Youngkaechulgamtang was more effective than mixture of 4 ingredients in the elevation of glutathione-S-transferase in acetaminophen-induced hepatotoxicity.

Oleanolic acid (OA), a triterpenoid known for its anti-inflammatory and anti-cancer properties, is commonly present in several medicinal plants but its anticoagulant activities have not been studied. Here, the anticoagulant properties of OA were determined by monitoring activated partial thromboplastin time (aPTT), prothrombin time (PT), fibrin polymerization as well as cell-based thrombin and activated factor X (FXa) generation activities. Data showed OA prolonged aPTT and PT significantly and inhibited thrombin catalyzed fibrin polymerization. In addition, OA inhibited the activities of thrombin and FXa and inhibited the generation of thrombin or FXa in human endothelial cells. OA also inhibited TNF-${\alpha}$-induced tissue factor expression on human endothelial cells. In accordance with these anticoagulant activities, OA showed an anticoagulant effect in vivo. These results indicate that OA possesses antithrombotic activities and suggest that daily consumption of a herb containing OA may be preventing thrombosis in pathological states.

Three species of genus Polygonum, namely P. cuspidatum, P. sachalinense and P. ellipticum are distributed in Korea. Polygonum ellipticum Migo is a perennial herb in Polygonaceous plants. The root of the plant (Polygoni Rhizoma, 'Ho-jang') have been used as laxative, diuretic and for the treatment suppurative dermatitis in the oriental medicine. As the part of the study for the comparison of the three species in their components, the authors attempted to isolate the anthraquinones and stilbene derivative from the rhizome of P. ellipticum. The methanolic extract of dried rhizome of this plant was fractionated into ether soluble and insoluble fraction and each fraction was applied to column chromatography to isolate above mentioned components. Anthraquinone derivatives were isolated first; comp. I, mp $204{\sim}205^{\circ}$ (physcion), comp. II, mp $254{\sim}255^{\circ}$ (emodin), comp. IV, mp $191{\sim}192^{\circ}$ $(emodin-8-O-{\beta}-D-glucoside)$ and comp. III, mp $280{\sim}282^{\circ}$ $({\beta}-sitosterol-glucoside)$. They were identified by chemical properties and UV, IR and NMR spectra and by the direct comparison with authentic samples. Stilbene derivative was isolated secondly; comp. V, mp $255{\sim}256^{\circ}$ which was reported to possess antibacterial and antifungal activities.
