The cessation of the long-term exposure to low doses of mercury ameliorates the increase in systolic blood pressure and vascular damage in rats.

This study aimed to verify whether a prolonged exposure to low-level mercury promotes haemodynamic disorders and studied the reversibility of this vascular damage. Rats were divided into seven groups: three control groups received saline solution (im) for 30, 60 or 90 days; two groups received HgCl (im, first dose, 4.6μg/kg, subsequent doses 0.

Aluminum exposure for one hour decreases vascular reactivity in conductance and resistance arteries in rats.

Aims: Aluminum (Al) is an important environmental contaminant; however, there are not enough evidences of Al-induced cardiovascular dysfunction. We investigated the effects of acute exposure to aluminum chloride (AlCl) on blood pressure, vascular reactivity and oxidative stress.

Methods And Results: Male Wistar rats were divided into two groups: Untreated: vehicle (ultrapure water, ip) and AlCl: single dose of AlCl (100mg/kg,ip).
