Myoglobinuric acute renal failure has three pathogenic mechanisms: tubular obstruction, renal vasoconstriction, and oxidative stress. The latter is generated through the iron released from the group hemo of the myoglobin. Iron induces the formation of high-activity oxygen free radicals that increase oxidative stress and provoke lipid peroxidation and cellular death.

Background: Accurate estimation of the Total Antioxidant Status (TAS) in the myoglobinuric acute renal failure (ARF) is necessary because its pathogenesis is believed to be mediated, at least in part, by the development of oxidative stress resulting from the generation of oxygen free radicals and reduced antioxidant defense system. The purpose of this study is to examine the TAS 24 and 72 h after glycerol injection in a model of myoglobinuric-ARF.

Experimental Design: The study was conduced in 28 Sprague-Dawley rats.
