| Research Abstract |
Hydrocortisone and methylprednisolone significantly increased glucocorticoid transcriptional activity and production of superoxide, and decreased expression and activation of endothelial nitric oxide synthase in cultured vascular endothelial cells. Thease effects were suppressed by spironolactone and eplerenone. Glucocorticoid excess enhanced oxidative stress and attenuated nitric oxide production through activation of mineralcorticoid recptor, leading to vascular endothelial dysfunction.
