  • Chungpesagan-Tang (CST), a Korean traditional prescription composed of oriental medical herbs, has been used successfully to improve human health and regimen. This study was designed to examine the inhibitory effects of CST against in vitro ischemia/reperfusion-induced inflammatory response. We have characterized the production of prostaglandin $E_2$ and arachidonic acid during ischemia/reperfusion in the human neuroblastoma SK-N-MC and human monocytic macrophage U937 cells and the inhibitory effect of CST on these inflammation-related substance formation has been found out in this study. This result suggested that CST used in this experiment reinforced antiinflammatory potentials and protected cells against ischemia/reperfusion-induced inflammatory resopnse.

  • This study was attempted to examine the acute toxicity and the effect of Sopunghwalhul-Tang water extract(SHTE) on analgesic action in mice, anti- inflammatory action in rats and blood pressure in rabbits. The results were as follows; SHTE showed 10% mortality at 2,000mg/kg(p.o.), had significant analgesic activity in the pain caused by 0.7% acetic acid and was shown to have significant anti-inflammatory activity in the edema-induced by 5% acetic acid at 450mg/kg. SHTE given into a ear vein of rabbits produced a dose-related vasodepressur responses. SHTE-induced hypotension was significantly inhibited by pretreatment with atropine, but was not affected by chlorisondamine, phentolamine, propranolol, and dephenhydramine.

  • SKI306X is a herbal extract prepared from three herbs Clematis mandshurica, Trichosanthes kirilowii and Prunella vulgaris. It showed strong antiinflammatory actions on carrageenan-induced edema, acetic acid-induced pain, adjuvant-induced arthritis, and oxygen radical-generated reactions. In this study, the acute toxicity of SKI306X was evaluated in rats by a single oral administration. Thirty male and thirty female rats were divided into 6 groups according to the dose levels, respectively. After oral administration of SKI306X with several doses (5.0 g/kg, 3.3 g/kg, 2.2 g/kg, 1.5 g/kg, 1.0 g/kg), mortality, clinical signs, body weight, and gross findings in organs were examined. No toxic effect was shown in terms of mortality, clinical signs, body weight changes and gross findings. It is suggested the LD$_{50}$ of SKI306X would be more than 5.0 g/kg in rats.s.

  • Natural glycoproteins can induce apoptosis of tumor cells and exert anti-tumor activity by immunomodulatory functions, cytotoxic and anti-inflammation effects, and inhibition of endothelial growth factor. Given their prospects as novel agents, sources of natural antitumor glycoproteins have attracted attention and new research directions in glycoprotein biology are gradually shifting to the direction of cancer treatment and prevention of neoplastic disease. In this review, we summarize the latest findings with regard to the tumor suppressor signature of glycoproteins and underlying regulatory mechanisms.

  • To separate anticaries and antiinflammation from Aloe vera peel, we investigated a inhibited effect of Streptococcus mutans JC-2 that was antibiosis, glucosyltransferase activity about aloe-emodin and barbaloin. Aloe-emodin and barbaloin had strong antibiosis activity against Streptococcus mutans JC-2, they were especially antibiosis effect to low growth and prolong lag phase at attachment concentration 100$\mu\textrm{g}$/mL. The reduction rate of a culture fluid became to lessen than the comparison group for aloe-emodin and barbaloin. The intracellular materials of Streptococcus mutans JC-2 were to leakage as much as attachment concentration addition of aloe-emodin and barbaloin but there was no significant difference membrane demage between two active substances. The activity of GTase was inhibited by aloe-emodin and barbaloin and their inhibition rate was respectively 99.8%, 98.4% at the attachment concentration 100$\mu\textrm{g}$/mL.

  • Yukmijihwangwon (YM) has been known to reinforce the vital essence and have antioxidant activities. This study was designed to examine the inhibitory effects of YM against in vitro hypoxia/reperfusion-induced inflammatory response. We have characterized the production of prostaglandin $E_2$ and arachidonic acid during hypoxia/reperfusion in the human neuroblastoma SK-N-MC and human monocytic macrophage U937 cells and the ingibitory effect of YM on these inflammation-related substance formation has been found out in this study. To investigate inhibition of COX expression by YM during hypoxia in vitro. This result suggested that YM used in this experiment reinforced antiinflammatory potentials and protected cells against hypoxia/reperfusion induced inflammatory response.

  • Three components, fraxetin-8-glucoside, esculetin-6-glucoside and mannitol, were isolated from the stem bark of Fraxinus chiisanensis var. stenophylla, F. japonica var. intermedia and F. densata. The MeOH extract of the cortex of F. densata had the antiinflammatory activity on the carrageenin-induced paw edema in rat. The MeOH extracts of the cortex of all three Fraxinus spp. have the potent analgesic activity on the HOAc-induced writhing syndrome in mouse and the hepatoprotective activity on the $CCl_4-induced$ fatty liver in rat: protection of ballooning formation and inhibition of sGPT and sGOT increased by $CCl_4$.

  • Panax ginseng, known as Koran ginseng, one of the most commonly used traditional plants, has been demonstrated to show a wide range of pharmacological applications. Ginsenosides are the major active ingredients found in ginseng and are responsible for the biological and pharmacological activities, such as antioxidation, antiinflammation, vasorelaxation, and anticancer actions. Existing studies have mostly focused on identifying and purifying single ginsenosides and investigating pharmacological activities and molecular mechanisms in cells and animal models. However, ginsenoside studies based on clinical trials have been very limited. Therefore, this review aimed to discuss the currently available clinical trials on ginsenosides and provide insights and future directions for developing ginsenosides as efficacious and safe drugs for human disease.
