Atrial natriuretic factor in chronic renal failure: studies in man and the rat.

abstract：:  NADPH oxidases (Nox) are reactive oxygen species (ROS)-generating enzymes that play important physiological roles in host defence and redox signalling. However, Nox activity is upregulated in the vascular wall during atherosclerosis and contributes to plaque formation by promoting oxidative stress and inflammation. ...
