Abstract Background Menopause is a natural physiological process that can impact various systems and organs, often leading to increased blood pressure. The combination of Panax ginseng and Angelica keiskei (Pg + Ak) is a formulation known to improve vascular function. Objective This study aimed to evaluate the in vivo effects of these combined plants on cardiovascular parameters in female rats experiencing menopause induced by ovariectomy. Methods Twenty-four 70-day-old female Wistar rats were randomly assigned to three groups: sham-operated (Sham), ovariectomized […]

Background: In menopause, there is greater cellular exposure to oxidative stress, related to the decreased antioxidative effects of estrogen. These metabolic changes favor the progression of cardiovascular diseases, such as atherosclerosis. Abnormal function of the aorta – the most important artery – is associated with many cardiovascular diseases. Collagen, especially types I and III, is one of the most important aortic wall components and it can be affected by many factors, including menopause. The 8-OHdG is one of the main […]

Abstract Background: Despite knowing that resveratrol has effects on blood vessels, blood pressure and that phytostrogens can also improve the endothelium-dependent relaxation/vasodilation, there are no reports of reveratrol’s direct effect on the endothelial function and blood pressure of animals with estrogen deficit (mimicking post-menopausal increased blood pressure). Objective: To verify the effect of two different periods of preventive treatment with resveratrol on blood pressure and endothelial function in ovariectomized young adult rats. Methods: 3-month old female Wistar rats were used […]
