  • To develop anticariogenic agents, Scutellariae Radix was tested for its antibacterial activity against Streptococcus mutans OMZ176 which is known as a strong cariogenic bacterium. The antibacterial activity was evaluated with disk plate method and minimal inhibitory concentration (MIC). The ethyl acetate fraction showed significant activity. By means of activity-guided fractionation, baicalein and ganhuangenin were isolated as the active principles. The MICs of these compounds were $100{\mu}g/ml$ and $200{\mu}g/ml$, respectively.

  • HAE-06 extract is a mixture of four medicinal plants, namely Lonicerae Folium et Caulis (Lonicera japonica), Scutellariae Radix (Scutellaria baicalensis), Adenophorae Radix (Adenophora triphylla var. japonica), and Polygonati Oddorati Rhizoma (Polygonatum odoratum var. pluriflorum). The HAE-06 extract demonstrated a concentration-dependent relaxing effect and enhanced cAMP production in bronchial smooth muscle that had been stimulated to contract with acetylcholine. Using a blocker, it was confirmed that the effect was through the β2-adrenergic receptor/cAMP/PKA pathway. In addition, it is thought that the HAE-06 extract has a bronchial smooth muscle relaxation effect by reducing the inflow of Ca2+ through the K+ and Ca2+ channels present in the sarcoplasmic membrane. If research continues in the future, it is believed that it will be possible to use it as a material for pharmaceuticals and functional foods.

  • Objectives : Scutellariae Radix (Hwanggeum in Korean) is the root of Scutellaria baicalensis Georgi. Scutellariae Radix is well known to be used as a medicine for common cold, upper respiratory infections, and to strengthen and regulate the immune system and anemia etc. Little is understood about the roles of Scutellariae Radix in the cytokine and chemokine secretion by immune cells. This study was designed to find out the effects of Scutellariae Radix on the cytokine and chemokine secretion in human mast cells (HMC-1). Methods : We treated hwanggeum according to consistency on HMC-1 and measured cytokines and chemokines levels using flow cytometry CBA system. Results : In hwanggeum treated group, the expression of interferon-inducible protein 10 (IP-10), monocyte chemoattractant protein-1 (MCP-1), chemokine (C-X-C motif) ligand 9 (CXCL9, MIG), interleukin 8 (IL-8), interleukin 2 (IL-2), interleukin 4 (IL-4), interleukin 5 (IL-5), interleukin 10 (IL-10), and interferon ${\gamma}$ (IFN-${\gamma}$) were decreased significantly. Conclusion : These results suggest that hwanggeum may support some of immune diseases by means of amiliorating some chemokines or cytokines such as IP-10, MCP-1, MIG, IL-8, IL-2, IL-4, IL-5, IL-10, and IFN-${\gamma}$.

  • Objectives : This study was conducted to evaluate the anti-hyperlipidemia effect of Scutellariae Radix, Aucklandiae Radix and Bupleuri Radix(SAB). Methods : FL83B cells were mouse liver hepatocytes, and we used this cell line. FL83B cells were treated with 0.5 mM oleic acid(OA) for 24 h, SAB extract was treated. After OA treatment, intracellular triglyceride (TG) and free fatty acid contents were measured with AdiopoRed™ assay and Free Fatty Acid Quantitation assay kit, respectively. Further, we evaluated several lipogenesis and metabolic markers such as sterol regulatory element-binding transcription factor-1c (SREBP-1c), acetyl-CoA carboxylase (ACC), fatty acid synthase (FAS), 3-hydroxy3-methyl-glutaryl CoA reductase (HMGCR), hormone-sensitive lipase (HSL), carnitine palmitoyltransferase (CPT-1), peroxisome proliferator activated receptor alpha (PPARα), and cluster of differentiation (CD36) using RT-PCR and Western-blot analysis. Results : OA markedly increased intracellular TG and free fatty acid, which plays a key role in reducing hepatic lipid accumulation, in FL83B cells. These increases were alleviated by SAB extract. The mRNA and protein expression of Fatty acid(FA) oxidation factors (CPT-1, PPARα), lipolysis factor(HSL), FA transporter(CD36), cholesterol synthesis factors (HMGCoA) and Lipodenesis (SREBP-1c, FAS, and ACC-1) were significantly increased by treatment of SAB extract in the OA-induced fatty liver cell model. Conclusions : In summary, the treat of SAB extract showed a significant reduction of the influx of fatty acids into hepatocytes, promoted the oxidation of fatty acids, and regulated fat synthesis-related factors, thereby regulating the accumulation of TG and free fatty acids.

  • Objectives : It has been reported previously that the roots of Scutellaria baicalensis (known as Huang-Gum in Korean, henceforth referred to as S. baicalensis) could prevent neuronal cell death after global cerebral ischemia. In Genuine Korean medicine, S. baicalensis is known to relieve fever in upper body, and it was thus thought to be able to alleviate deteriorations in brain function. Methods : The protective effects of S. baicalensis against post-stroke memory retardation using 4-vessel occlusion model were examined in the present study. Results : S. baicalensis was shown to significantly alleviate the deficits in learning and memory by increasing the fraction of time spent in the quadrant in which the platform was initially placed ($34.9\;{\pm}\;3.2%$, p < 0.05) compared to that of the ischemia group ($28.0\;{\pm}\;2.5%$). The cytoprotective effect of S. baicalensis on CA1 hippocampal neurons was evaluated by measuring the neuronal cell density. Neuronal cell density in S. baicalensis extracts-treated ischemia group ($138.0\;{\pm}\;13.6\;cells/mm^2$) was significantly increased compared to saline-treated ischemia group ($22.1 \;{\pm}\;9.3\;cells/mm^2$, p < 0.05). In the study of OX-42 immunohistochemistry, S. baicalensis could decrease the micrgial activation in hippocampus after brain ischemia. Conclusion : These results may provide experimental support for the use of S. baicalensis in treating post-stroke memory impairment.

  • Objectives: The purpose of this study was to investigate anti-obesity effect of Scutellariae Radix extract combined with metformin. Methods: Male C57BL/6 mice, 4 weeks of age, were used to set high-fat diet induced obesity model. They were grouped NOR (normal control), HFD (high fat diet control), MET (metformin, 100 mg/kg/day), MH2 (metformin 50 mg/kg/day+Scutellariae Radix 200 mg/kg/day), and HG4 (Scutellariae Radix 400 mg/kg/day). MET, MH2, and HG4 were orally administered for 10 weeks. Body weight was measured every week. Fasting blood glucose, triglyceride, total cholesterol (TC), high density lipoprotein, glutamic oxaloacetic transaminase (GOT), and glutamic-pyruvic transaminase (GPT) were measured before sacrifice. Oral glucose tolerance test (OGTT) was also performed. Organ weight and internal fat weight were measured after sacrifice. Results: MH2 group showed a reduction of body weight when compared with HFD group. MH2 group showed stable blood level control which was calculated areas under the curves by OGTT. TC, GOT, GPT level, internal fat, and organ weight in MH2 group reduced. Conclusions: The combined treatment of Scutellariae Radix and Metformin has impact on treating obesity. Further studies are needed to evaluate the effect of Metformin and herbal medicine combination therapy.

  • Objectives : The aim of this study was to investigative the effects of Gagambojungikgi-tang (GBT), a Korean herbal medicine, on the immune mediators, T cell proliferation and wound healing in the recombinant Sj26 (rSj26) antigen induced atopic dermatitis(AD) model mice. Methods : GBT is the water extracts prepared from mixture of Ginseng Radix, Astragali Radix, Angelicae gigantis Radix, Atractylodes Rhizoma alba, Aurantii nobilis Pericarpium, Glycyrrhizae Radix, Artemisia iwayomogi Herba, Scutellaria Radix, Lonicera japonica Flos. This is a modified prescription of Bojungikgi-tang, which has been used for the treatment of indigestion, and immunological disease in east-asian countries. GBT was orally administered or externally applied at difference doses. The levels of immune mediators [(IgE, IgG1, prostaglandin E2 (PGE2), Th1/Th2 cytokines], T cell proliferation, and wound healing in the rSj26 or chemical antigen induced AD model BALB/c were investigated. Results : GBT dose-dependently suppressed the release of TNF-${\alpha}$, IL-$1{\beta}$ (Th1 cytokines), IL-4, IL-10 (Th2 cytokines), PGE2 (inflammatory mediators) and T cell proliferation. But GBT increased the production of IFN-${\gamma}$ (Th1 cytokine). Furthermore, A wound healing effect of GBT was similar to external application of dexamethasone. Conclusions : These results suggest that GBT suppresses the inflammatory mediators and regulates the Thl/Th2 cytokines, and promotes the wound healing. Therefore, these properties may contribute to the strong anti-AD effect of GBT.

  • Objectives : This study aims at examining the immuno-modulating activity in the fermentative extract of the root of Scutellaria baicalensis Georgi (Scutellariae Radix) on the production of inflammatory mediator in LPS-stimulated RAW264.7 mouse macrophages. Method : Measurements were done for the influences on the cell viability, generation of hydrogen peroxide in cells and nitric oxide (NO) generation using the macrophage of mouse with the specimen SBS as the fermentative extract of Scutellariae Radix (SBS) with Saccharomyces cerevisiae STV89. Result : As a result of carrying out MTT assay to check the cellular toxicity of the fermentative extract of Scutellariae Radix, any excessive toxicity to the macrophage did not occur from treatments by concentration for SBS. SBS increased the generation of hydrogen peroxide in the macrophage. SBS suppressed the NO generated in macrophages and SBS concentration higher than $25{\mu}g/mL$ significantly suppressed the increased NO generated in LPS-stimulated macrophages. SBS concentration higher than $25{\mu}g/mL$ significantly suppressed the generation of IL-6, IL-10, IL-12p40 and MCP-1 in LPS-stimulated macrophages. Conclusion : Our findings indicate that SBS has an immuno-modulating activity in macrophage activation through suppressing the generation of inflammatory substances, NO, IL-6, IL-10, IL-12p40 and MCP-1.
