Endothelial function was assessed by vasorelaxation responses to acetylcholine (ACh) and sodium nitroprusside (SNP) in isolated aortic rings, while serum malondialdehyde (MDA) and superoxide dismutase (SOD) activity were measured as markers of oxidative stress. LN administration elevated blood pressure impaired ACh-induced vasorelaxation, increased MDA, and reduced SOD activity. SIPH at 500 mg/kg significantly reduced blood pressure, restored endothelial-dependent relaxation, decreased lipid peroxidation, and enhanced antioxidant defense. Notably, the combination of SIPH with captopril exerted synergistic antihypertensive effects, producing greater improvements in vascular reactivity and oxidative balance than either treatment alone.
