Objective To study the effect of Proanthocyanidins and its composition with Anti- inflammatory active ingredi-ents such as Asiaticoside, Curcumin or tea polyphenols on cytokine levels and intracellular cholesterol during foam cellformation induced by oxidized low density lipoprotein (ox- LDL). Methods Mouse monocyte- macrophage cell line RAW264.7 cells were cultured in vitro and the cells were stimulated by ox- LDL for 24h to transform foam cells. IL- 1βmRNA and TNF- α mRNA was evaluated by real time PCR. An enzymatic colorimetric assay was used to determine intracellular cholesterol. Results Proantho-cyanidins and its composition with Asiaticoside, Curcumin or tea polyphenols can significantly reduced the cholesterol esters and the ratio of total cholesterol in the foam cells, inhibite foam cells formation and expression of IL- 1βmRNA and TNF- α mRNA . The composition of Proanthocyanidins and curcumin had the strongest effect. Conclusion Proanthocyanidins and its composi-tion play a role of anti- atherosclerosis by reducing intracellular cholesterol ester content, foam cells formation and the inflamma-tory response.
