Background : To investigate the effect of Hwanggeumjackyak-tang (HJT) on Dextran sulfate sodium (DSS) induced ulcerative colitis. Methods : The experimental animals were divided into three groups; group 1, normal group(Normal); group 2, DSS-induced colitis and untreated group(UT+DSS); group 3, DSS-induced colitis and HJT 200 mg-treated group(HJT200+DSS). We evaluated cytotoxicity after HJT administration and confirmed the anti-inflammatory effect by histological changes in the intestine and genetic analysis of mucosal cells after HJT administration for each group. In addition, microbiological weapons and metabolites in faeces were examined, and the correlation between gut microbiome and metabolites was also investigated. Result : HJT was not observed to be cytotoxic, even at relatively high concentrations, and was effective in protecting the barrier and preventing intestinal inflammation by suppressing the increase in mucus secretion and the expression of inflammatory factors in mucosal cells. HJT treatment affected the increase in the amount and diversity of the gut microbiome in faeces and the increase in metabolites thought to be involved in alleviating inflammation in the gut. Conclusion : This study demonstrates the therapeutic potential of HJT in ulcerative colitis. Further studies should be carried out to confirm our findings.

Background/Aims: We aimed to evaluate the histologic features predictive of prognosis and correlate them with endoscopic findings in patients with ulcerative colitis (UC) having complete or partial mucosal healing (MH). Methods: We prospectively collected and reviewed data from patients with UC who underwent colonoscopy or sigmoidoscopy with biopsy. Complete and partial MH were defined as Mayo endoscopic subscores (MESs) of 0 and 1, respectively. Histologic variables, including the Nancy index (NI), predicting disease progression (defined as the need for medication upgrade or hospitalization/surgery), were evaluated and correlated with endoscopic findings. Results: Overall, 441 biopsy specimens were collected from 194 patients. The average follow-up duration was 14.7 ± 7.4 months. There were 49 (25.3%) and 68 (35.1%) patients with MESs of 0 and 1, respectively. Disease progression occurred only in patients with an MES of 1. NI ≥ 3 was significantly correlated with disease progression during follow-up. Mucosal friability on endoscopy was significantly correlated with NI ≥ 3 (61.1% in NI < 3 vs. 88.0% in NI ≥ 3; p = 0.013). Conclusions: Histological activity can help predict the prognosis of patients with UC with mild endoscopic activity. Mucosal friability observed on endoscopy may reflect a more severe histological status, which can be a risk factor for disease progression.

In general, Reucedani Radix (Peucedanum japonicum Thunbergis: PJ) is the Korean traditional herbal medicine used to remove dampness, to relieve pain, and spasm. So, PJ folium is believed to have the same effects. The aim of this study is to investigate the alleviation of dextran sulfate sodium (DSS) induced ulcerative colitis in mice by PJ folium. 25 mice were divided into 5 groups: normal, DSS, DSS + 100 mg/kg PJ folium (PJ100), DSS + 500 mg/kg PJ folium (PJ500), and DSS + 150 mg/kg 5-amino salicylic acid (5-ASA) groups. Body weights, colon lengths, histological changes in colon tissue, and spleen weights were observed. Inflammatory cytokines such as IL-$1{\beta}$, IL-6, and TNF-${\alpha}$ level in plasma were measured by ELISA. IL-$1{\beta}$, IL-6, and TNF-a mRNA expression in colon tissue were detected by RT-PCR. In the results, body weight lose was inhibited in PJ100, PJ500, and 5-ASA groups, but it was not different compared with DSS group, significantly. PJ500 group showed the preventive effects of colon length shorten and histological changes in colon tissues as good as 5-ASA group. The weight of spleen was increased in DSS group but it reduced in PJ100, PJ500, and 5-ASA groups. Moreover, IL-$1{\beta}$ and TNF-${\alpha}$ cytokine levels in plasma were reduced in PJ500 and 5-ASA groups. IL-$1{\beta}$, IL-6, and TNF-a mRNA expression in colon tissue were inhibited in PJ100, PJ500, and 5-ASA groups and it was significantly different compared with DSS group. In conclusion, PJ folium showed the alleviative effect on DSS induced ulcerative colitis in mice.

Saengmaeksan (SMS) is a well known Korean traditional herbal prescription, which consists of 3 different herbs, Radix Ophiopogonis, Radix Ginseng, and Fructus Schisandrae. SMS has been commonly used in various disease including respiratory system and cardiovascular System in Korea. The objective of this study is to find out the improving effects of SMS against Dextran Sulfate Sodium (DSS)-induced ulcerative colitis. SMS reduced clinical signs of DSS-induced colitis, including body weight loss, shorten colon length, and increased disease activity index. The results showed that SMS significantly inhibited the activation of nuclear factor-${\kappa}B$ p65 in the colon tissues of DSS-treated mice. In addition, we observed that result showed that the levels of IL-6 in plasma were increased in DSS treated group compared to those of the normal group, but these increased levels were reduced by administration with SMS. Taken together, these findings suggest that SMS has improving effects on DSS-induced ulcerative colitis, which may explain its beneficial effect in the regulation of chronic intestinal inflammation.

Objectives : Although the pharmacological effects of anti-inflammatory and antioxidant action of Atractylodes macrocephala Koidzumi water extract (AM) have been proven from many studies, reports on the antioxidant effect of AM on ulcerative colitis (UC) are scarce. Therefore, we aimed at evaluating the anti-oxidant effect of AM on the DSS-induced UC model. Methods : To induce ulcerative colitis, 8-week-old male Balb/c mice received 5% DSS in drinking water for 1 week. After 1 week of adaptation, mice were divided into four groups (n=8 each) for use as normal (Normal), DSS Control (Control), DSS + AM 100 mg/kg (AM100)-treatment, DSS + AM 200 mg/kg (AM200)-treatment. After 1 week of the experiment, the animals were sacrificed, and the extracted colon tissue was analyzed for protein through western blot. Results : As a result of confirming the macroscopic changes in colon tissues to confirm the therapeutic effects of AM, the decrease in colon length was suppressed in the AM treatment group compared to the control group. In addition, as a result of biochemical analysis, AM administration significantly reduced serum glutamic oxalacetic transaminase, glutamic pyruvate transaminase levels and tissue malondialdehyde levels. As a result of confirming the protein expression level through western blot, AM administration significantly decreased the expression of NADPH-related proteins such as NOX2, p22^phox, and iNOS, but significantly increased the expression of SOD, catalase, and GPx-1/2. Conclusions : AM may improve DSS-induced UC in mice by modulating NADPH and antioxidant-related proteins. In conclusion, AM showed an antioxidant effect through the improvement of oxidative stress on UC.

Purpose : Banhasasim-tang (BHSST) has been applied for treating the symptom of gastric stuffiness, which is similar to dyspepsia. The object of this study was to observe the healing effect of BHSST on the indomethacin (IND)-induced gastric ulcer in rats. Methods : Three different dosages of BHSST (400, 200 and 100 mg/kg) were orally administered 30 min before IND treatment; 6 hrs after IND treatment, the changes on the gross lesion scores, fundic histopathology, myeloperoxidase (MPO) activity, lipid peroxidation and antioxidant defense system (glutathione contents, catalase (CAT) and superoxide dismutase (SOD) activities) were observed, and compared with the activity of the synthetic anti-ulcer drug, a representative proton pump inhibitor omeprazole (OME) 10 mg/kg. Results : All three different dosages of BHSST treatment in the IND-induced gastric ulcer rats, significant and dose dependent decreased gastric damages - hemorrhagic gross lesions, gastric mucosa MPO levels and histopathological gastric ulcerative lesions - were detected as compared with the IND treated control rats. BHSST also strengthened the antioxidant defense systems - decreased the level of lipid peroxidation and CAT activity but increased the level of GSH and SOD activity, and BHSST 200 mg/kg showed similar anti-ulcerative effect as compared with OME 10 mg/kg. Conclusions : The results obtained in this study suggest that BHSST has favorable effects against IND-induced gastric damages, through significant and dose-dependent decreasing gastric damages and the strengthening of the body's antioxidant defense systems with direct anti-inflammatory effects.

Purpose: The object of this study is to observe the anti-ulcerative effects of BK-1202 (IGM), a mixed herbal formula consisting of 9 herbal drugs, which have been traditional Korean medicine for treating various digestive diseases, on indomethacin-induced gastric ulcer in rat. Methods: Three different doses of IGM extract (200, 100 and 50 mg/kg) were orally administered once 30 min before indomethacin treatment. Six hours after indomethacin treatment, changes in the gross lesion scores, fundic histopathology, MPO activity and antioxidant activities were observed. The results were compared with two reference groups treated with omeprazole (10 mg/kg), antioxidant and proton pump inhibitor, and DA-9601 (100 mg/kg), a standardized extract of the herb Artemisiaasiatica. Results: In all three doses of IGM extract, significantly decreased gastric damages were observed in the indomethacin-induced gastric ulcer rats, when compared with the indomethacin-treated control rats. IGM extracts also strengthened the antioxidative defense systems, decreasing the level of lipid peroxidation and catalase activity while increasing the superoxide dismutase and glutathione contents. IGM extracts showed similar anti-ulcerative effects to those shown by equal dose of DA-9601, and the effects of 50 mg/kg IGM extracts were comparable to those of 10 mg/kg omeprazole. Conclusion: The results obtained in this study suggest that IGM extract has favorable effects on the indomethacin -induced gastric damages by strengthening the antioxidative defense systems and enhancing anti-inflammatory effects.
