This study aims to evaluate the anti-inflammatory effect of Coptidis Rhizoma (CR) extract for atopic dermatitis through maintaining skin barrier and regulating Th2 cell differentiation. We divided NC/Nga mice into 3 groups as follows; atopy-like dermatitis induced group with CR treatment (CT, n=10), no treatment group(Ctrl), atopy-like dermatitis elicited group(AE). Atopy-like dermatitis was induced to NC/Nga mice by sensitizing with dermatophagoides farinae(DfE) on 7, 8, 9, 11, 12, and 13th week. After inducing atopic dermatitis, CR extract was administered 20 mg/kg daily for the experimental duration to the CT group. We measured the integrity of lipid layers in the epidermis and Th2 differentiation through immunohistochemical staining against filaggrin, loricrin, IL-4, and IL-13. We also measured the distribution of subcutaneous collagen fibers by the Masson's trichrome staining. Administration of CR significantly inhibited the reduction of lipid layers in the skin that caused atopy. The expression of IL-4, IL-13, each of which is a cytokine secreted by T helper type 2 (Th2) cells, was markedly suppressed in the CT group as compared with AE group (p<0.05). CR treatment also decreased the expression of iNOS, $p-I{\kappa}B$. Atopic dermatitis induced dermatological damage to skin, such as hyperplasia of epithelium, and capillary proliferation was significantly reduced by CR administration. CR effectively inhibited the thinning of the skin barrier and inflammatory responses in atopic dermatitis-induced mice. In particular, it showed anti-inflammatory effects by reducing the expression of IL-4 and IL-13, Th2 cell cytokines, which play a crucial role in development of atopic dermatitis. Therefore, CR can be a good candidate to ameliorate and treat atopic dermatitis.

Objective : The purpose of this study was to analyze the effects of HwangRyunHaeDok-Tang and combinations of constituent herbs on the arterial contraction. Methods : In order to investigate the effects Scutellariae Radix. Coptidis Rhizoma, Phellodendri Cortex and Gardeniae Fructus, in which one of them, two of them, and all of them, were used to exam. Results : The results were summarized as follows; 1. HwangRyunHaeDok-Tang significantly inhibited the contraction of artery induced by Norepinephrine(NE). However the atonic effect was slightly blunted when the vascular endothelial cell was removed. No significant change in the atonic effect of HwangRyunHaeDok-Tang was found when $_L-NNA$ was used as a preliminary treatment. These results indicate that the vascular atonic effect by HwangRyunHaeDok-Tang is slightly dependent on the endothelial cell, and that the HwangRyunHaeDok-Tang works directly to the vascular smooth muscle in creating the vascular atonic effect. 2. The pretreatment of HwangRyunHaeDok-Tang extract significantly inhibited the contractile response to additive application of $Ca^{2+}$ in the strips which were contracted by NE in $Ca^{2+}$-free solution. 3. HwangRyunHaeDok-Tang extract increased the contraction of arterial smooth muscle induced by KCl. Therefore, it can be concluded that HwangRyunHaeDok-Tang may block the NE-receptor or receptor-operated $Ca^{2+}$ channel. 4. It was determined that Scutellariae Radix, Coptidis Rhizoma and Phellodendri Cortex among the ingredients of HwangRyunHaeDok-Tang have a vascular atonic effect. In addition, those ingredients plays a role in strengthening the atonic effect by working with other herbal medicines. Gardeniae Fructus causes the blood vessel to contract. but it does not influence the atonic effects of other herbal medicines. However Gardeniae Fructus tends to inhibit the vascular atonic effect of Phellodendri Cortex. Conclusion : Based on the above results, it can be said that HwangRyunHaeDok-Tang can be applied to cure hypertension considering those three herbs have significant effects of relaxation.

Objective : Chronic acid reflux esophagitis (CARE), one of gastroesophageal reflux disease (GERD) is increasing worldwide. Coptidis rhizoma extract (CRE) is a traditional herb that cures a variety of diseases. This study was conducted to evaluate the protective effect of CR on rats with chronic acid reflux esophagitis. Methods : The antioxidant activities were evaluated through radical scavenging assays using 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2'-azino-bis (3-ethylbenzothiazolin-6-sulfonic acid) (ABTS) radical scavenging assays. CARE was surgically induced in 5-week-old male SD rats by ligating the border between forestomach and glandular portion with a 2-0 silk tie and covering the duodenum using 18-Fr $N{\acute{e}}laton$ catheter. To evaluate the esophageal protective effect of CRE, rats were divided into 3 groups: Nor (normal rats), Veh (chronic acid reflux esophagitis induced rats), CR (chronic acid reflux esophagitis induced rats treated with CRE 200 mg/kg body weight). Results : The administration of CRE significantly prevented the mucosal injury of the esophagus tissue and histological findings improved the esophageal lesion. It has been shown that inflammation is prevented by the increase of antioxidant-related factors (Nrf-2, HO-1, SOD, catalase, and GPx-1/2) through the antioxidant pathway of esophageal tissue. The administration of CRE reduced the increase of serum peroxynitrite ($ONOO^-$) and markedly reduced the protein expression of inflammatory mediator such as $NF-{\kappa}Bp65$, $p-I{\kappa}B{\alpha}$, iNOS, and IL-6. Conclusions : Overall, these results suggest that CRE administration confirmed the protective effect of esophageal mucosa, suggesting that it is a potential treatment for chronic acid reflux esophagitis.

The present study was undertaken to estimate the antibacterial effect of a combination of C. rhizoma, L. Flos, and P japonica (1:1:1) extracts (CLP1000) and a combination of the herbal extract mixture and dioctahedral smectite (CLPS1000) against murine salmonellosis. At the concentration of CLP1000 and CLPS1000 0.5 mg/ml, the antibacterial effect was not showed on Salmonella typhimurium (S. typhimurium). On the other hand, the antibacterial effect against S. typhimurium was observed at the concentration of CLP1000 and CLPS1000 1.0 mg/ml. Oral administration of Smectite, CLPl000, and CLPS1000 at the dose of 10 mg/ml showed a therapeutic effect for S. typhimurium infected BALB/c mice. The mortality of Smectite, CLP1000 and CLPS1000-treated mice was 90%, 90%, and 70% at 12 days, respectively, while that of untreated mice was 100% at 9 days after a lethal dose of S. typhimurium infection. The results of our study strongly indicate that CLPS1000 has potential as an effective of salmonellosis.

Objectives : The current treatment regimens for patients with nephrotic syndrome due to membranous nephropathy(MN) are based on steroids or immunosuppressive therapy with the aim of reducing proteinuria and improving outcome. Although these treatments attenuate the deterioration of renal function in MN patients, it has been suggested that all are burdened by significant toxicity. Therefore, more specific and less toxic therapies are needed. This study was to evaluate the effects of Coptidis Rhizoma Extract(CRE) on the MN induced by cBSA in mice. Methods : Mice were divided into 4 groups. One group named for 'Normal' was injected with a saline solution not to be immunized. The rest groups were treated as follows; After mice were immunized with 0.2 mg of cBSA and Freund's complete adjuvant one time every two weeks for 6 weeks, they received intra-peritoneal injection of 10 mg/kg of cBSA daily for 4 weeks. Also, they were divided into 3 groups. The first named for 'Control' was not given CRE. The second for 'CRE-250' was given oral administration of 250 mg/kg of CRE daily for 4 weeks. The third for 'CRE-500' was given 500 mg/kg of CRE. All of mice were sacrificed 4 weeks after the first immunization. We measured a body weight and 24hrs proteinuria as well as serological analysis. The morphologic changes of renal glomeruli were also observed with a light microscope and an electron microscope. Results : The levels of 24 hrs proteinuria, triglyceride, IgG, IL-6 were significantly decreased in both CRE groups. And the level of IgM was significantly decreased in CRE-250 group. In histological findings of kidney tissue, thickening of GBM and deposition of electron-density were consideraly decreased in both CRE groups. Conclusions : The present study suggests that CRE is highly effective when treating mice with MN induced by cBSA. More clinical data and studies are to be done for efficient application.

The object of this study was to observe the gatro protective effects of BJS-mix001, a mixed herbal formula consisted of 4 herbal drugs Pinelliae Rhizoma : Coptidis Rhizoma : Massa Medicata Fermentata : Ostreae Testa = 1 : 1 : 1 : 1 (g/g) mixtures, which were main component of oriental medicine for treating various digestive diseases, in indomethacin induced gastric damages in rats. Three different dosages of BJS-mix001 (200, 100 and 50 mg/kg) were once orally administered 30 min before indomethacin treatment. Six hrs after indomethacin treatment, changes on the gross lesion scores, fundic histopathology, MPO activity and anti oxidant activities were observed. The results were compared with omeprazole, antioxidant and proton pump inhibitor 10 mg/kg and DA-9601, a standardized extract of the herb Artemisia asiatica 100 mg/kg treated group, respectively. As results of all three different dosages of BJS-mix001 in the indomethacin induced gastric damaged rats, significant decreased gastric damages were detected as compared with the indomethacin treated control rats. BJS-mix001 also strengthened the antioxidative defense systems - decreased the level of lipid peroxidation and catalase activity but increased the level of superoxide dismutase and glutathione contents. BJS-mix001 showed similar gastro protective effects as compared with equal dosage of DA-9601, and BJS-mix001 50 mg/kg showed slighter effects as compared with omeprazole 10 mg/kg, in the present study. The results obtained in this study suggest that BJS-mix001 showed favorable effects in the indomethacin induced gastric damages mediated by strengthening of the antioxidative defense systems.
