摘要

There is considerable evidence that oxidative stress from superoxide and other reactive oxygen species (ROS) plays an important role in the development of cardiovascular diseases and hypertension and in the pathogenesis of renal diseases, producing vascular, glomerular, tubular, and interstitial injury (13, 37). It is known that ROS can be utilized in signal transduction events and play an important role in the regulation of cell biology and physiology. Thus, it has been demonstrated that ROS participate in BP control and kidney function (39, 40). In this regard, ROS can influence vascular reactivity either directly or via intermediate pathways. ROS also increase tubular reabsorption of sodium by inhibition of the natriuretic effects of NO and/or by affecting the activities of sodium transporters in the kidney (7, 12, 25).
