Abstract

The aim of this study was to evaluate the anti-inlfammatory effects of Glycyrrhiza glabra Linne extract on ulcerative colitis induced by 3% dextran sulfate sodium in mice. The experimental animals were divided into six groups: control(normal), DSS-induced colitis(control), 1 mg/kg, 10 mg/kg, and 100 mg/kg of Glycyrrhiza glabra Linne extract, and 150 mg/kg 5-aminosalicylic acid(5-ASA)(positive control). We evaluated the pathological disease activity index(DAI), change in weight, colon mucosa damage and myeloperoxidase(MPO) in colon mucosa. Treatment with 10 mg/kg and 100 mg/kg of Glycyrrhiza glabra Linne extract led to significant loss of body weight, the decrease of MPO activity and clinical symptoms such as DAI and histological change. In particular, 100 mg/kg Glycyrrhiza glabra Linne extract led to markedly greater improvement than 150 mg/kg 5-ASA treatment. These results suggest that Glycyrrhiza glabra mediated anti-inflammatory action on colorectal sites may be a useful therapeutic approach to ulcerative colitis.
