摘要

Abstract : Intermittent fasting (IF), a type of feeding regimen where the frequency of eating is reduced enhances cardiovascular stress adaptation and improves cardiovascular risk factors in rats. Data on the effect of IF on the endothelium is not common, so we examined whether IF showed similarity to documented beneficial effects of caloric restriction on endothelium-dependent vasodilatory responses of rat aortic rings. 25 young male Wistar rats had ad libitum (AL) access to food and 25 others were provided with food every other day for 2 months, during which their weight was measured every 2 weeks. Vascular reactivity of abdominal aorta was simultaneously evaluated using dual wire myographs. Weight gain was greater in the AL group (P<0.001) at all weighing intervals. Acetylcholine (ACh; 10~(-10)-10~(-5)M) produced greater (P<0.05) vasorelaxation in IF rats at the two highest concentrations. IF reduces weight gain in young male rats and improves their aortic endothelium-dependent vasorelaxation.
