ABSTRACT
Objective:
To observe the effect of supplementation with anthocyanins (ANTH)purified from outlayer of black rice (BRF) on atherosclerotic (AS) plaque formation and inflammatory signal-transduction.Methods:
Forth five male ApoE-defieient mice of 4 w age, were randomly divided into 3 groups positive control (Group A), BRF (Group B ), ANTH (Group C), 15 in each group. Another 15 male ApoE-deficient mice served as negative control (Group D ). Group A and D were fed AIN-93G purified diet, Group C and B fed the same diet with 5% BRF not containing ANTH and 0.39% ANTH (containing 42% total flavonoids) respectively. The animals were fed for 20w, then blood, hearts and aortas were examined to verify inflammatory signal transduction.Results:
There were no visible AS plaques in group D but much more severe in group A and B than C respectively. Compared with group A, supplememation of ANTH of BRF significantly increased the activity of T-NOS and cNOS, decreased the activity of iNOS but not significantly. The level of protein expression of ICAM- 1, NF-?B gene and mRNA expression of COX-2 gene were significantly decreased in aorta.Conclusion:
The action of anthocyanins of BRF could be attributed to its anti-inflammatory activity to reduce COX-2, INOS and ICAM-1 expression which might be modulated by NF-?B.
