IMPLICATION S Available evidence from RCTs suggests that resveratrol supplementation significantly reduced TNF-α and hs-CRP levels .
Significant improvement in inflammatory markers  support resveratrol as an adjunct to pharmacologic management of metabolic diseases
PURPOSE The evidence has suggested that resveratrol has anti-inflammatory effect ; however , the results are inconsistent and inconclusive .
The aim of this study was to assess the effect of resveratrol supplementation on the levels of inflammatory markers through a systematic review and meta- analysis of available r and omized controlled trials ( RCTs ) .
Resveratrol attenuates the inflammatory reaction induced by ischemia/reperfusion in the rat heart.
The role of resveratrol ( Res ) in inflammation induced by ischemia/reperfusion is not well understood . The aim of the present study was to investigate whether Res modulates neutrophil accumulation and tumor necrosis factor-α ( TNF-α ) induction in an ischemia/reperfusion-injured rat heart model . The rats were r and omly exposed to sham surgery , myocardial ischemia/reperfusion ( MI/R ) alone , MI/R + Res , MI/R + Res + L-NG-nitroarginine methyl ester ( L-NAME ) and MI/R + Res + methylene blue ( MB ) . The results demonstrated that compared with MI/R , Res reduced the myocardial infa rct area , myocardial myeloperoxidase levels , serum creatinine kinase and lactate dehydrogenase levels , and serum and myocardial TNF-α production . All the effects of Res demonstrated were inhibited by L-NAME ( a nitric oxide ( NO ) synthase inhibitor ) and MB [ a cyclic guanosine monophosphate ( cGMP ) inhibitor ] . Thus , Res  produces cardioprotective and anti-inflammatory effects . These effects may be associated with an increase in NO production , the inhibition of neutrophil accumulation , TNF-α induction and cGMP signaling pathways in myocardium subjected to
