The impact of Magnesium on vascular tone is mainly due to its calcium antagonist activity
resulting in smooth muscle relaxation. The present study was designed to determine the
roles of nitric oxide and calcium ions in magnesium-induced vasorelaxation in rats aortic
rings through these enzyme pathways. In this study, the aorta contracted with NE (3x10-6M),
pre-incubated with cyclooxygenase (COX) and epoxygenase inhibitors, then dose response
curve (DRC) made to magnesium sulfate (MgSO4) served as a control. On the other hand …
