Therapeutic action of physical exercise on markers of oxidative stress induced by chronic kidney disease.

Aims: To investigate the effects physical training exerts on markers of oxidative stress in rats with chronic kidney disease (CKD).

Main Methods: Twenty-four male Wistar rats were divided into four groups (n=6): sham, CKD, exercise-sham and exercise-CKD. Surgical reduction of the renal mass was performed (5/6 nephrectomized) and exercise was conducted on a treadmill (50 min/day up to 1 km/h for, 5 days/week for eight weeks).

Physical exercise prevents the exacerbation of oxidative stress parameters in chronic kidney disease.

Objective: Reactive oxygen species play an important role in the pathogenesis of chronic kidney disease (CKD). Physical exercise was suggested as a useful approach to diminish impaired oxidative defense mechanisms. This study sought to observe the effects of physical training before the induction of renal lesions on oxidative stress parameters in animals induced for CKD.

Effect of different models of physical exercise on oxidative stress markers in mouse liver.

The aim of this study was to investigate the effect of different protocols of physical exercise on oxidative stress markers in mouse liver. Twenty-eight male CF1 mice (30-35 g) were distributed into 4 groups (n = 7) - untrained (UT), continuous running (CR), downhill running (D-HR), and intermittent running (IR) - and underwent an 8-week training program. Forty-eight hours after the last training session, the animals were killed, and their livers were removed.

The effect of n-acetylcysteine and deferoxamine on exercise-induced oxidative damage in striatum and hippocampus of mice.

The aim of this study was to analyze the effects of intense exercise on brain redox status, associated with antioxidant supplementation of N-acetylcysteine (NAC), deferoxamine (DFX) or a combination of both. Seventy-two C57BL-6 adult male mice were randomly assigned to 8 groups: control, NAC, DFX, NAC plus DFX, exercise, exercise with NAC, exercise with DFX, and exercise with NAC plus DFX. They were given antioxidant supplementation, exercise training on a treadmill for 12 weeks, and sacrificed 48 h after the last exercise session.

Attenuation of bleomycin-induced lung injury and oxidative stress by N-acetylcysteine plus deferoxamine.

Reactive oxygen species (ROS) play an important role in the pathogenesis of pulmonary injury and antioxidant therapy may be useful with impaired oxidative defense mechanism. This study examines the effect of N-acetylcysteine (NAC) and deferoxamine (DFX) on inflammatory indicators and oxidative stress in the lungs of mice exposed to bleomycin (BLM). The animals received endotracheally a single dose of BLM (2.
