Popis: | Summary Purpose The objective of this study is to assess the effect of the candesartan on the progression of atherosclerosis through the downregulation of NF-κβ and interference with oxidative pathway. Methods Twenty-four rabbits were assigned to three groups: control group fed normal diet; induced untreated group fed 1% cholesterol diet; and treated candesartan group also fed 1% cholesterol diet. Plasma lipid profiles were measured, and ELISA for plasma cytokines and chemokine was performed. Analyses of NF-κβ and VCAM-1 were performed using Western blotting with RT-PCR for NF-κB activity at mRNA. Doppler ultrasound was used to evaluate aortic intima-media thickness, and atheroma was detected by H&E staining. Immunofluorescent staining was performed to confirm accumulation of monocytes and PMNs. Results Candesartan markedly reduced the levels of the plasma lipid profile including total cholesterol [TC], triglycerides [TG], and LDL-C, while significantly elevating levels in the plasma HDL-C, in addition to reducing cytokine (TNF-α, IL-6, IL-1β) and chemokine levels (MCP-1). Also, it decreased the aortic malondialdehyde (MDA) concentration and elevated the aortic glutathione (GSH) level compared with untreated animals (P |
