The effect of lunasin from Indonesian soybean extract on histopatologic examination and cox-2 expression in dextran sodium sulfate-induced mice colon.

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. PMID: 30697362 [PubMed]
