Abstract/OtherAbstract:
ABSTRACT:: Ferulic acid is a simple phenolic acid commonly present in cereals. In this study, changes in heart and kidney structure and function were measured in young L-NAME-treated Wistar rats and 10 month old spontaneously hypertensive rats (SHR) alone and following chronic treatment with ferulic acid (50 mg/kg/day); n=6-10; *p<0.05. Systolic blood pressures were increased following L-NAME treatment (control 125±2 mmHg, L-NAME 205±6* mmHg after 8 weeks) and in SHR (250±2 mmHg; WKY 149±4 mmHg). Hypertensive rats developed left ventricular (LV) hypertrophy, increased ventricular diastolic stiffness (κ; Wistar, 21.4±1.6; L-NAME, 30.1±0.9*; WKY, 24.1±0.9; SHR 29.5±0.7) and fibrosis of heart and kidneys. Treatment with ferulic acid reduced systolic blood pressure (L-NAME+ferulic acid, 157±4*; SHR+ferulic acid 214±8* mmHg), reduced left ventricular diastolic stiffness (L-NAME+ferulic acid, 25.2±0.5*; SHR+ferulic acid 26.3±0.5*) and attenuated inflammatory cell infiltration, ferric iron accumulation and collagen deposition in left ventricles and kidneys. Ferulic acid improved both endothelium-dependent relaxation in isolated thoracic aortic rings and antioxidant status by increasing SOD and catalase activity in heart and kidneys. Ferulic acid decreased plasma liver enzyme activities and plasma creatinine concentrations. Thus, ferulic acid improved the structure and function of the heart, blood vessels, liver and kidneys in hypertensive rats.
