Chronic effects of OA, elaidic acid and stearic acid on systolic BP. Sprague–Dawley rats received vehicle (V), OA (1 g·kg−1), elaidic acid (EA; 1 g·kg−1), or stearic acid (SA; 1 g·kg−1) p.o. every 12 h for 14 days. Each value represents the mean ± SEM (n = 10). *, P < 0.05 vs. vehicle-treated rats (ANOVA).
