Abstract:

The present study examined the efficacy of using longevinex, a commercially available resveratrol formulation, to lower blood cholesterol in hypercholesteromic rabbits. New Zealand white rabbits were randomly divided into two groups (n = 6 per group), one group was given high cholesterol diet for 3 months while the other group fed regular diet served as control. The high cholesterol diet fed group was further subdivided into two groups (n = 6 per group), one group was given longevinex resveratrol while the other group given vehicle only served as control. Longevinex was given by gavaging up to a period of 6 months. Longevinex-treated rabbits exhibited lowering of plasma cholesterol level. Inhibition of arterial plaque formation was noticed even after 1 month. Longevinex-treated hearts demonstrated improved ventricular recovery when isolated working hearts were subjected to 30 min of ischemia followed by 2 h of reperfusion. Aortic flow and developed pressure during post-ischemic reperfusion period were significantly higher for the longevinex-treated hearts compared to those in control group of hearts. Myocardial infarct size was also lower in the treated group compared to that for the untreated group. These results indicate cholesterol-lowering ability of longevinex, which appears to reflect in its ability to protect the hypercholesteromic hearts from ischemic reperfusion injury.
