  • Previously, several prenylated flavonoids having a C-8 lavandulyl moiety were found to inhibit cyclooxygenase-1 (COX-1) as well as 5-lipoxygenase (5-LOX), and sophoraflavanone G was the most potent inhibitor against these eicosanoid generating enzymes among the prenylated flavonoids tested. In this investigation, effects of sophoraflavanone G on COX-2 induction from RAW 264.7 cells and in vivo inflammatory response were studied. Sophoraflavanone G inhibited prostaglandin E$_2$(PGE$_2$) production from lipopolysaccharide (LPS)-treated RAW cells by COX-2 down-regulation without significantly affecting COX-2 activity at 1 50 $\mu$M. Other prenylated flavonoids including kuraridin and sanggenon D also down-regulated COX-2 induction at 10-25 $\mu$M, lirhile kurarinone and echinoisoflavanone did not. In addition, sophoraflavanone G shelved in vivo anti-inflammatory activity against mouse croton oil-induced ear edema and rat carrageenan paw edema via oral (2-250mg/kg) or topical administration (10 - 250 $\mu\textrm{g}$/ear). Although the potencies of inhibition were far less than that of a reference drug, prednisolone, this compound showed higher anti-inflammato교 activity when applied topically, suggesting a potential use for several eicosanoid-related skin inflammation such as atopic dermatitis.

  • It is thought that highly reactive oxygen species generated after strokes plays a key role in damaging the brain. We examined free radical scavenging activity and neuroprotective effects of several medicinal herbs in a rat model of transient ischemia. Free radical scavenging property of medicinal herbs was examined in vitro using 1,1-diphenyl-2-picrylhydrazyl stable free radical. Transient ischemia was induced by intraluminal occlusion of the right middle cerebral artery for 120 min, followed by reperfusion for 22 hr in rats. Aqueous extracts of 8 medicinal herbs (200 mg/kg) were orally administered twice to transient ischemic rat prior to reperfusion and 2 hr after reperfusion. Total infarction volume in the hemisphere ipsilateral to the ischemia-reperfusion was significantly decreased in 7 groups treated with Sophora flavescens, Lycopus lucidus, Sanguisorba officinalis, Caesalpinia sappan, Albizia julibrissin, Rubia akane, Psoralea corylifolia, or Prunella vulgaris. However, neuroprotective effects of these medicinal herbs were not correlated with their antioxidative activities. These results suggest that these medicinal herbs exert neuroprotection via antioxidative as well as unknown mechanism.

  • Many medicinal plants have been used for the treatment of edema, jaundice, and gonorrhea in traditional Oriental medicine. This screening study was designed to search the positive inotropic effects of herbal extracts in beating rabbit atria. Aquarius extracts of twenty six herbs were examined in atrial mechanical dynamics such as pulse pressure and stroke volume and atrial natriuretic peptide (ANP), one of the main hormones involved in the regulation of the body fluid and blood pressure homeostasis in perfused beating rabbit atria. Sophora flavescens Ait., Rheum officinale Baill., Acorus gramineus Sol., Chelidonium majus L., Pulsatilla koreana Nakai., Reynoutria japonica Houtt., Euphorbia lathyris L., Pyrrosia lingua (Thunb.) Farwell, Poncirus trifoliata Rafin., Anemarrhena asphodeloides Bunge, Kochia scoparia Schrad. significantly increased stroke volume and pulse pressure. However, those herbal extracts were not induced ANP secretion. We clarified the eleven herbal extracts for the positive inotropic effect independent of ANP secretion in beating rabbit atria. Thus these results provide a beneficial data for the treatment of the impairment of body fluid and blood pressure in traditional Oriental medicine.

  • Herbal mixture water extract of (Chrysanthemum morifolium, Portulaca oleracea, Sanguisorba officinalis, Sophora flavescens, Phellodendron amurense, Cnidium monnieri) which exhibit several beneficial effects including acne and skin diseases, was tested for anti-microbial activity and anti-inflammation effects. The herbal mixture extract showed antimicrobial activity against Stapylococcus epidermis, and Propionibacterium acne. The growth of Stapylococcus epidermis, and Propionibacterium acne was inhibited completely by addition of 1.0% of the extract. Also in the present study we examined the mixture extract on compound 48/80 induced allergy and LPS induced cyclooxygenase-2(COX-2) gene expression in RAW 264.7 macrophage. The results indicated the ear swelling and histamine release induced by compound 48/80 were dose-dependently reduced, ranging 28-60%, and 48-72% , respectively. Furthermore the extract inhibited the expression of LPS-induced COX-2 proteins and mRNAs without an appreciable cytotoxic effects on RAW 264.7 cells. The LPS-induced cytokine gene expression including IL-$1{\beta}$, TNF-$\alpha$, and IL-6 were dose-dependently suppressed by the mixture extract. Based on these results, it is concluded that the herbal mixture water extract can be applied to the acne and skin diseases therapy.

  • Objective : Many patients take antihypertensive drugs as well as herbal medicines at the same time in order to treat other symptoms or to keep their well-being. In this study, interactions between herbal medicines and synthetic antihypertensive drugs were analyzed. Methods : To investigate the interaction between herbal medicines and synthetic antihypertensive drugs, three electronic databases, including OASIS, Mediline and Sciencedirect were searched. Experimental and clinical studies on the interaction between herbal medicines and antihypertensive drugs were independently reviewed and included. Results : Analyzing selected studies, twenty herbs were found to interact with antihypertensive drugs. Herbs found to increase the antihypertensive effect were Panax ginseng, Carthamus tinctorius, Magnolia officinalis, Silybum marianum, Scutellaria baicalensis, Schisandra chinensis, Sophora flavescens, Piper nigrum, Curcuma longa, Ginkgo biloba, Juncus effuses and Hydrastis canadensis. In contrast, Commiphora myrrha, Rhodiola rosea, Hypericum perforatum, Eurycoma longifolia, and Daturae metel were found to inhibit the antihypertensive effect. Stephania tetrandra could increase or decrease the effect depending on the type of antihypertensive drug. Epedria sínica was suspected of pharmacodynamic interaction with antihypertensive drug. Glycyrrhiza uralensis has been reported to have serious side effects in combination with antihypertensive drugs. Conclusion : These results imply that when used in combination with herbal medicines and synthetic antihypertensive drugs, proper doses and herbs which are to avoid need to be informed to the patients. Despite concerns about interactions between herbal medicines and synthetic drugs, related research is very limited. More systematic researches are needed to give information on patient safety as well as to guide clinical practice.

  • Host plants of the Henosepilachna vigintioctomaculata are known as Solanaceae plants such as potato, tomato, eggplant and Lycium chinense. Henosepilachna vigintioctomaculata (Motschulsky) cause continuous damage from early June to mid-August in leaves of L. chinense under environmental-friendly management in Cheongyang, Chungnam. The developmental period of egg and larva of H. vigintioctomaculata were investigated. H. vigintioctomaculata were reared on L. chinense at several temperatures, for example, 15, 20, 25 and $30^{\circ}C$ in the laboratory. In addition, the control effect of 5 eco-friendly agricultural materials were examined. As results, hatching rate is the highest to 91% at $25^{\circ}C$. Egg periods were 10.8, 7.7, 5.1 and 3.7 days at each tested temperature, respectively. And the total developmental periods from egg to adult were 42.7, 26.3, 18.4 and 19.4 days at each tested temperature, respectively. Otherwise, their eclosion rates from pupa to adult were showed 58%, 77%, 85%, 65% at each tested temperature, respectively. As a result of the control effect, both adults and larvae of H. vigintioctomaculata were shown a high mortality to mixture with extract of Sophora flavescens, Chenopodium ambrosioides and Melia azedarach. Additional, larvae is shown high mortality to extract of Azadirachta indica and Cymbopogon nardus. Thus H. vigintioctomaculata might be controled by using plant extract of eco-friendly agricultural materials in due season.

  • The anti-metastatic activity of water extract of Samguikoeuitang (WSGKE) consisting of Ginseng Radix, Angelicae Radix, Sophora flavescens and Coicis Semenwas examined. Ethanol extract of Samguikoeuitang (ESGKE) showed significant cytotoxicity against colon 26-M3.1 carcinoma cells, while WSGEK did not. However, WSGKE significantly increased the production of IL-6 and IL-12 in thioglycollate-induced macrophages from Balb/c mice, whereas ESGKE did not. WSGKE significantly increased natural killer (NK) cell cytotoxicity against effecter YAC-1 cells in an Effecter cells/Target ratio dependent manner. Also, WSGKE significantly suppressed lung metastasis after i.v. injection of colon26-M3.1 carcinoma cells. Inhibitory effect of WSGKE on lung metastasis totally abolished in NK cells-deficient mice by treatment with anti-asialo GM1 serum. In addition, the combination treatment of cisplatin and WSGKE (100 ${\mu}g$/mouse) prolonged the lifespan of mice inoculated by colon26-M3.1 cell. These findings suggest that WSGKE can inhibit lung metastasis and prolong life span via immunological enhancement as a Biological Response Modifier.

  • The heat extracts of six kinds of medicinal herbs (Scutellaria baicalensis, Sophora flavescens, Citrus unshiu pericarpium, Lonicera japonica, Perilla frutescens, Benincasa hispida) were tested for non-specific immune response and disease resistance effects related with fish diseases on olive flounder, Paralichthys olivaceus. The preventive effects of 6 herbal mixtures against bacterial disease on cultured flounder were examined follow as feeding EP absorbed with the heat extract of six kinds of medicinal herbs. For feeding trial for 12th week, weight gain and serum analysis of fish fed various groups were not significant differences. Lysozyme activity of the 0.01 % treated group on 4th week showed significant increase. Histopathology of the administrated group for feeding period showed no particular signs of tissue degeneration. At 0.01% oral experimental group, relative percent survival (RPS) were only 50% to 75% for four weeks and eight weeks group by intraperitoneal injection with E. tarda. The results suggest that heat extracts of six kinds of medicinal herbs (0.01%) would be effective to enhance the nonspecific immunity and protective ability of olive flounder against fish pathogen.
