Objectives : This study was undertaken to define the effect of Diospyros kaki L. Radix or Diospyros kaki L. Folium on phenylephrine-induced arterial contraction and the mechanism of Diospyros kaki L. Radix or Diospyros kaki L. Foliuminduced relaxation. Methods : In order to investigate the effect of Diospyros kaki L. Radix or Diospyros kaki L. Folium on contracted rabbit carotid arterial strips, transverse strips with intact or damaged endothelium were used for the experiment using organ bath. Diospyros kaki L. Radix or Diospyros kaki L. Folium extract was infused into contracted arterial strips induced by phenylephrine. To analyze the mechanism of Diospyros kaki L. Radix or Diospyros kaki L. Folium-induced relaxation, Diospyros kaki L. Radix or Diospyros kaki L. Folium extract was infused into contracted arterial strips induced by phenylephrine after treatment with indomethacin, $N{\omega}-nitro-L-arginine$, methylene blue or tetraethylammonium chloride, and $Ca^{2+}$ was infused into contracted arterial strips induced by phenylephrine after treatment of Diospyros kaki L. Radix or Diospyros kaki L. Folium in a $Ca^{2+}$-free solution. Results : Diospyros kaki L. Radix or Diospyros kaki L. Folium showed relaxation effect on arterial strip with endothelium contracted by phenylephrine, but in the strips without endothelium, Diospyros kaki L. Radix or Diospyros kaki L. Folium-induced relaxation was significantly inhibited. The endothelium-dependent relaxation induced by Diospyros kaki L. Radix or Diospyros kaki L. Folium was decreased by pretreatment with $N{\omega}-nitro-L-arginine$ or methylene blue but it was not observed in the strips pretreated with indomethacin or tetraethylammonium chloride. When $Ca^{2+}$ was applied to the strips which were contracted by phenylephrine in a $Ca^{2+}$-free solution, arterial contraction was increased. However, pretreatment with Diospyros kaki L. Radix or Diospyros kaki L. Folium inhibited contractile response to $Ca^{2+}$. Conclusions : Diospyros kaki L. Radix or Diospyros kaki L. Folium may suppress influx of extra- cellular $Ca^{2+}$ through the formation of nitric oxide in the vascular endothelial cells.

This study was performed to investigate the effect of Mori Folium and Crataegus pinnatifida leave extracts on liver damage induced by CC1$_4$ in rats. 30％ and 60％ methanol extracts of Mori Folium and Crataegus pinnatifida leaves were administered orally at the dose of 10 mg/kg on every day for 6 days and liver damage was induced by intraperitoneal injection of $CCl_4$ (0.4 ml/kg) on 6th day. 30％ Methanol extracts of Mori Folium treated group showed significant protective effect on hepatotoxicity with the lowest Glutamic Oxaloacetic Transaminase (GOT) and Glutamic Pyruvic Transaminase (GPT). The low density lipoprotein (LDL) levels of 30％ methanol extracts of Mori Folium and Crataegus pinnatifida leave and 60％ methanol extracts of Mori Folium treated groups were significantly lower than normal group, respectively. In particular, LDL level of 30％ Mori Folium extracts treated group was significantly decreased compared to $CCl_4$ treated group. These results support that Mori Folium and Crataegus pinnatifida leave extracts are hepatoprotective effects against hepatotoxicity induced by $CCl_4$.

Objective : The objective of this study was to investigate the antioxidant effects of Mori Folium extract. Methods Total antioxidant status was examined by total antioxidant capacity(TAC) and total antioxidant response(TAR) against potent free radical reactions. The effect of Mori Folium extract was examined by measuring total phenolic content, concentration at which 1,1-dipheny1-2-picrylhydrazyl(DPPH) radical scavenging activity was inhibited, inhibitory effect on lipid peroxidation, and the effect on reactive oxygen species(ROS) generation. Results : 1. TAC and TAR of Mori Folium extract at the concentration of 5 mg/ml were 1.61 and 1.24 mM Trolox equivalents, respectively. 2. Total phenolic content of Mori Folium extract at the concentration of 5 mg/Ml was 1.70 mM gallic acid equivalent. 3. Concentration of Mori Folium extract at which DPPH radical scavenging activity was inhibited by 50% was 2.29 m9/m4 as compared to 100% by Pyrogallol solution as a reference. 4. The inhibitory effect of the extract on lipid peroxidation was examined using rat liver mitochondria induced by FeSO$_4$/ascorbic acid. Mori Folium extract at the concentration of 10 mg/ml significantly decreased thiobarbituric acid reactive substances(TBARS) concentration. The extract prevented lipid peroxidation in a dose-dependent 5. The effect of Mori Folium extract on reactive oxygen species(ROS) generation was examined using a celt-free system induced by hydrogen peroxide FeSO$_4$. Addition of 1 mg/ml of Mori Folium extract significantly reduced dichlorofluorescein(DCf) fluorescence. The extract caused concentration-dependent attenuation of the increase in DCF fluorescence, indicating that the extract significantly prevented ROS generation in vitro. Conclusion ; The antioxidant effects of Mori Folium extract seem to be due, at least in part, to the prevention offree radical-induced oxidation, fllowed by inhibition of lipid peroxidation.

Objectives : Mori Folium is used for hyperlipidemia or diabetes. The study was designed to test the anti-obesity effect of Mori Folium on body weight, hepatic fat accumulation and serum lipid level. Methods : The extract from Mori Folium was made by the pharmacy department of Kyung-hee oriental medical hospital. Normal diet, high-fat diet, 30% reduced diet and Mori Folium groups were set. The normal group was administered normal rat food, but the other three groups were administered high fat food. We measured body weight once a week. After 3 weeks experiment, hepatic lipid accumulations were measured. Also we compared serum lipid levels among the 4 groups after 3 weeks. Results : Mori Folium had no effect on body weight, but the 30% reduced diet had an inhibitory effect on body weight gain. Mori Folium had more inhibitory effect on hepatic fat accumulation than a 30% reduced diet. Mori Folium also has more inhibitory effect on serum triglyceride than 30% reduced diet. Conclusions : Mori Folium has anti-obesity effect on hepatic lipid accumulaion and serum triglyceride level in high fat diet induced rats.

Objectives : This study was designed to propose the effective herb-processing method of Ginkgo Folium in the Oriental medicine. Methods : The books, papers and patents were used to examine the recent usage of Ginkgo Folium. Results : The toxic ingredients of Ginkgo Folium should be removed. Accordingly, a detoxification process using a nonpolar solvent and a vinegar-roasting process in sequence are desirable to assure its safety. The previously developed standard extract (e.g. EGb 761) could be used as a powdered Oriental medicine as well. Conclusions : Ginkgo Folium could not be used widely to treat the diseases in ancient Oriental medicine, because the toxic ingredients could not be removed by any method until recent year. However, Ginkgo Folium might be used as a herbal medicine that invigorates the blood without any difficulty using herb-processing methods suggested in this paper.

The aim of this study was to investigate a potential effect of treatment of spontaneously hypertensive rats (SHR) with Pini Folium or Leonuri Herba extracts. Male SHR were treated with extracts for 2 or 4 weeks starting at 13 weeks of age. We found that oral treatment with the methanol extract from Pini Folium or Leonuri Herba (1g/Kg/day) significantly decreased mean blood pressure to 85.4% and 78.6% respectively in compare with untreated control SHR. Treatment with the extract from Pini Folium for 4 weeks during hypertension development phase (starting 9 weeks of age) resulted in a partial prevention of hypertension development. There were no significant differences for body weight between untreated and Pini Folium treated SHR.
