Fig. 4From: Cerebral microvascular dysfunction in metabolic syndrome is exacerbated by ischemia–reperfusion injuryEvaluation of microvascular endothelial function by intravital fluorescence microscopy. Percentage of variation from the basal values of arteriolar inner diameter after topical acetylcholine (Ach, 10−6 μM) administration in the cranial window of rats fed a normal or high-fat diet (CTL-sham, HFD-sham) after cerebral ischemia and reperfusion (CTL-IR or HFD-IR). Values represent the mean ± SEM. n = 4 per group. *p < 0.05, ***p < 0.001 versus CTL-sham, #p < 0.05 versus CTL-IRBack to article page
