0.05).It could also decrease the times of wet manure induced by folia sennae,while it was of no effect on diarrhea induced by castor oil. CONCLUSION: Volatile oil from A.longiligulare T.L.Wu has anti-inflammation,analgesic and anti-diarrhea effect related to the cure for ulcerative colitis.
RESUMEN
AIM: To investigate antioxidative and antinitrosative effects of volatile oil from A.longiligulare T.L.Wu on dextran sulfate sodium(DSS)-induced ulcerative colitis mice. METHODS: Balb/c mice were fed with 4% DSS solution for 7 d to induce ulcerative colitis.Using biochemical method,the activity of antioxidative enzyme SOD,MDA and NO were determined in normal,model,SASP and three mouse's groups with low,moderate and high volatile oil from A.longiligulare T.L.Wu respectively.At the same time,the activity of iNOS was also measured by immunohistopathology. RESULTS: The concentration of MDA and NO were reduced and SOD increased significantly in high-and moderate-volatile oil groups compared with those in the model group.The activity of iNOS was reduced significantly in high-and moderate-volatile oil groups compared with those in the model group.The results demonstrated that the expression of iNOS was significantly inhibited in DSSinduced ulcerative colitis mice after being treated with high or moderate-dosage volatile oil. CONCLUSION: Volatile oil from A.longiligulare T.L.Wu has antioxidative and antinitrosative effects which may be one of the mechanism for treating UC.
