The purpose of the study was to investigate the antimicrobial activity of the methanol extract of Coptidis rhizome against the type strains of cariogenic bacteria, Streptococcus mutans and Streptococcus sobrinus, and the periodontopathogens, Porphyromonas gingivalis, Prevotella intermedia, Treponema denticola and Aggregatibacter actinomycetemcomitans. The antimicrobial activities of the crude extract and the methanol extract fractions of Coptidis rhizome separated by silica gel chromatography were evaluated by determining the minimal bactericidal concentration (MBC) values, using the microdilution method. The cell viability test of the extracts of Coptidis rhizome on the KB cells was also studied by methyl thiazolyl tetrazolium (MTT) assay. Our results showed that the 11th fraction (F11) of the methanol extract had the greatest antimicrobial activity against the tested bacteria, with no associated cytotoxicity on the KB cells, upto a concentration of $50{\mu}g/ml$. These results suggest that the silica gel chromatography fraction F11 of the methanol extract of Coptidis rhizome, could be useful in the development of oral hygiene products as an antimicrobial agent for the prevention of dental caries and periodontal diseases.

During a screening program to search the anticolitic herbal medicines, 80% ethanol extract of the rhizome of Anemarrhena asphodeloides (AA) was found to potently inhibit the expression of proinflammatory cytokines TNF-${\alpha}$ and IL-1${\beta}$, as well as the activation of NF-${\kappa}B$ in LPS-stimulated colonic macrophages, followed by that of the rhizome of C. chinensis (CC). AA also potently inhibited TNBS-induced colitic markers, shortening of the colon and increase of macroscopic score, myeloperoxidase activity, TNF-${\alpha}$, IL-1${\beta}$, and IL-6, in mice. The synergistic effect of CC against the anticolitic effect of AA was investigated. CC synergistically inhibited the anticolitic effect of AA. AC-mix (AA+CC, 1:1) potently inhibited them. AC-mix also inhibited the activation of NF-${\kappa}B$, as well as the expression of TNF-${\alpha}$, IL-1${\beta}$, IL-6, iNOS and COX-2. The effects of AC-mix against oxazolone-induced colitis were investigated in mice. AC-mix also potently inhibited oxazolone-induced inflammatory markers, colon shortening, macroscopic score, myeloperoxidase activity, NF-${\kappa}B$ activation and proinflammatory cytokines. Overall, the anti-colitic effect of AC-mix was superior to that of mesalazine. Based on these findings, AC-mix may improve colitis by inhibiting NF-${\kappa}B$ activation.

Objectives: We performed this study to compare the antidiabetic effects of Coptidis Rhizoma (CR) and its major component berberine with gliclazide. Materials and Methods: Diabetic rats induced by injection of streptozotocin (STZ) 55mg/kg were treated with CR 100, 200, 400mg/kg and berberine 100mg/kg. After rats were treated for 5 days, serum glucose, total cholesterol, triglyceride, BUN, creatinine and antioxidant levels were determined. Results: The cytotoxic effects of CR (0.1, 0.01, and 0.001mg/mL), berberine and gliclazide ($0.1{\mu}M$, $1{\mu}M$, and $10{\mu}M$) were tested in rat insulinoma (RIN) cells induced with 5mM STZ. The levels of fasting blood glucose, total cholesterol, triglyceride, BUN and creatinine of CR and berberine treated groups were reduced as much as that of gliclazide group in comparison to control groups, whereas total antioxidant levels increased. In vitro experiments showed that CR and berberine have a cytoprotective effect on RIN cells.

Objectives : This research has been done to investigate the anti-inflammatory effect of Coptidis Rhizoma extracts. Method : Coptidis Rhizoma was extracted by $100^{\circ}C$ water. The extract (CC : Extract of Coptis chinensis rhizome) was used to examine its effects on the cell viability of mouse macrophage Raw 264.7 cell line. Also the production of nitric oxide (NO), the c-jun N-terminalkinase (JNK) activation and the production of cytokines such as (IL)-5 were evaluated in lipopolysaccharide (LPS)-stimulated Raw 264.7 cells. After the CC and LPS were applied to Raw 264.7 cells which were cultured for 24 hours, the MTT assay was performed. Result : The CC extracts didn't affect the viability of macrophage cells. However, the extracts inhibited the NO production and the JNK activation significantly in LPS-stimulated macrophage cells treated with 100 and $200{\mu}g/mL$ concentrations. The CC extract, also, impeded the production of inflammation-related factors and cytokines such as KC, VEGF, MCP-1, GM-CSF, IL-$1{\alpha}$, IL-5, IL-6, and IL-12p40 in LPS-stimulated macrophage cells at the concentration higher than $25{\mu}g/mL$. The production of basic-FGF concentration of 50 and $100{\mu}g/mL$, the production of IP-10 at $100{\mu}g/mL$, and the production of IFN-${\gamma}$ at $25{\mu}g/mL$, respectively. Conclusion : The CC prepared using $100^{\circ}C$ water showed the significant anti-inflammatory effect such as the inhibition not only on the production of NO, KC, VEGF, MCP-1, GM-CSF, IL-$1{\alpha}$, IL-5, IL-6, and IL-12p40 in LPS-stimulated macrophage cells at or higher than the concentration of $25{\mu}g/mL$, but also on the JNK activation at 100 and $200{\mu}g/mL$.

Objectives : The purpose of this study is to observe the effect of Coptidis Rhizoma (CCE-extract of C. chinensis Rhizome) in induction of immune protein on mouse macrophages. Methods : To analyze cytokines interleukin(IL)-$1{\alpha}$, IL-3, IL-9, IL-12p40, IL-13, IL-17, Monocyte Chemoattractant Protein(MCP)-1 induced by macrophages, mouse macrophages were incubated with CCE and was measured. Results : IL-$1{\alpha}$ measurement, CCE showed significant inhibition only at concentration level of 200 ${\mu}g/mL$. IL-3, MCP-1 measurement, CCE showed significant inhibition only at concentration level of 100, 200 ${\mu}g/mL$. IL-9 measurement, CCE showed significant inhibition only at concentration level of 50 ${\mu}g/mL$. IL-13 measurement, CCE showed significant inhibition only at concentration level of 50, 100, 200 ${\mu}g/mL$. The IL-12p40, IL-17 levels indicated no changes at 25, 50, 100, 200 ${\mu}g/mL$ on mouse macrophages. Conclusions : CCE did not significantly increased inflammatory cytokines IL-$1{\alpha}$, IL-3, IL-9, IL-12p40, IL-13, IL-17, Monocyte Chemoattractant Protein(MCP)-1 on mouse macrophages. It was verified CCE does not trigger cytokine related hypersensitivity reaction of organism or exacerbation of acute/chronic inflammatory disease.

The aim of this study is to evaluate the anti-inflammatory effect of Hataedock treatment using Coptidis Rhizome and Glycyrrhiza Uralensis (CG) mixed extract in allergic rhinitis induced NC/Nga mice. We divided NC/Nga mice into 3 groups as follows; allergic rhinitis-induced group after CG Hataedock treatment (CGT, n=10), no treatment group (Ctrl), allergic rhinitis elicited group (ARE). To induce allergic rhinitis, NC/Nga mice of 3 weeks age were sensitized on 7, 8 and 9week by Ovalbumin (OVA) antigen in intranasal space. Hataedock using CG extract was administered on week 3 in allergic rhinitis-induced group (CGT) after Hataedock treatment. To identify distribution of Interlukin (IL)-4, Cluster of differentiation 40 (CD40), high-affinity IgE receptor ($Fc{\varepsilon}RI$), substance P, Matrix metallopeptidase 9 (MMP-9), Nuclear $factor-{\kappa}B$ ($NF-{\kappa}B$) p65, Inducible nitric oxide synthase (iNOS) and Cycloxygenase-2 (COX-2), we used histological examination. CGT significantly inhibited IL-4 and CD40 response compared with ARE. The reduction of Th2 cytokine expression decreased inflammatory mediators such as $Fc{\varepsilon}RI$, substance P, MMP-9, $NF-{\kappa}B$ p65, iNOS and COX-2. Such immunological improvement induced reduction of respiratory epithelial damage and mucin secretion in goblet cell. These results indicate that Hataedock treatment suppresses allergic rhinitis through modulating of Th2 responses and diminishing various inflammatory mediators in nasal mucosal tissue. It might have potential applications for prevention and treatment of allergic rhinitis.
