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 …
