【 摘 要 】

Inflammatory bowel disease (IBD) is a condition describing chronic gastrointestinal inflammation. Chronic inflammation in colon can develop into colon cancer. Lunasin has been known to inhibit inflammatory reactions induced by lipopolysaccharide in vitro. The effect of lunasin to inhibit inflammation in vivo is not widely known. In this study, we analyzed the effect of lunasin from soybean to decrease the risk of inflammation by analyzing histopathologic feature and the expression of COX-2. 30 mice are divided into 6 groups. Normal group was not induced by dextran sodium sulfate (DSS). The other groups were induced by 2% DSS through drinking water for 9 days. After 9 days, negative control group did not receive any treatment. The other groups received treatment given lunasin dose 20 mg/kg body weight (BW) and 40 mg/kg BW, commercial lunasin and positive control given aspirin. Treatment was performed for 5 weeks. Inflammatory colon histopathologic examination and immunohistochemical score of COX-2 proteins were analyzed using statistical tests. Lunasin dose 20 mg/kg BW and 40 mg/kg BW were able to significantly reduce inflammation (P<0.05) performed by histopathologic feature with an average score of 2.52 and 2.16 COX-2 expression decreased significantly (P<0.05) with an average score of 43.674 and 33.349. Lunasin dose 20 mg/kg BW and 40 mg/kg BW were able to inhibit inflammation and decrease the expression of COX-2 in colon induced by DSS.
