Haemodynamic and hormonal effects of doxazosin, a long-acting alpha 1-adrenoceptor antagonist (2 mg) were compared with placebo in six normal men. Doxazosin at 2 mg produced lower supine systolic blood pressure and plasma cortisol concentration than control at 4 h only, but these changes were not sustained. Both supine and standing pulse rate were increased by active drug after 6 h. In this acute study doxazosin did not affect plasma renin or aldosterone concentrations.

Apelin, a (neuro) vasoactive peptide, plays a prominent role in controlling water balance and cardiovascular functions. Apelin and its receptor co-localize with vasopressin in magnocellular vasopressinergic neurons. Apelin receptors (Apelin-Rs) are also expressed in the collecting ducts of the kidney, where vasopressin type 2 receptors are also present.

Objective: This study aims to explore the role of estrogen in providing cardioprotective benefits to premenopausal women, examining how hormonal differences between sexes influence the prevalence of cardiovascular diseases (CVDs) in women.
Materials And Methods: Eighteen female Wistar rats were equally distributed into three treatment groups. Animals in Group I (sham-operated) and Group II (ovariectomized [OVX]) received oral saline solution at a dose of 2 mL/kg.

The glycocalyx is an essential structural and functional component of endothelial cells. Extensive hemodynamic changes cause endothelial glycocalyx disruption and vascular dysfunction, leading to multiple arterial and venous disorders. Chronic venous disease (CVD) is a common disorder of the lower extremities with major health and socio-economic implications, but complex pathophysiology.
