In this study, we investigated the effect of L-carnosine (CAR) on prooxidant-antioxidant balance in several tissues of rats exposed to chronic stress. Both cold and immobilization stresses were applied to rats at the same time. In the stress group, rats were placed in restraint cages and kept in a cold room (+4°C) for 1 h for 21 days (5 days a week). Rats(More)
d-galactose (GAL) causes aging-related changes and oxidative stress in the organism. We investigated the effect of carnosine (CAR) or taurine (TAU), having antioxidant effects, on hepatic injury and oxidative stress in GAL-treated rats. Rats received GAL (300 mg/kg; s.c.; 5 days/week) alone or together with CAR (250 mg/kg/daily; i.p.; 5 days/week) or TAU(More)
Rats were injected with isoproterenol (ISO; 110 mg/kg, ip, 2 doses, 24 h interval) to induce acute myocardial infarction (AMI) and were sacrificed 6 and 24 h after the last ISO injection. The heart tissue, plasma and erythrocytes of these rats were evaluated for cardiac markers and oxidative stress parameters. Levels of cardiac troponin T (cTnT) and the(More)
The aim of this study was to investigate the effect of carnosine (CAR) alone and together with vitamin E (Vit E) on alcoholic steatohepatitis (ASH) in rats. ASH was induced by ethanol (3 times; 5 g/kg; 12 h intervals, via gavage), followed by a single dose of lipopolysaccharide (LPS; 10 mg/kg; i.p.). CAR (250 mg/kg; i.p.) and Vit E (200 mg(More)
Testicular torsion can be thought of as an ischemia/reperfusion (I/R) injury to the testis. This study aimed to investigate the effects of taurine (TAU) and carnosine (CAR), which are strong antioxidants, on experimental testicular I/R injury model. Male Wistar albino rats were divided into four groups with eight animals in each. A sham operation was(More)
Methylglyoxal (MG) is generated from glycolytic metabolites, lipid peroxidation, glucose autooxidation and protein glycation. It is a prooxidant inducing oxidative stress and formation of advanced glycation end products (AGE). Effect of carnosine (CAR) as an antioxidant on toxicity due to MG has generated interest. In this study, rats were given(More)
Binge drinking of alcohol is known to cause cardiac dysfunction in some drinkers. This study was designed to examine the effect of ethanol on rat heart tissue with an experimental model mimicking human binge drinking. Female Sprague-Dawley rats were given ethanol diluted with normal saline (40%, v:v) by gavage at the dose of 5.0g/kg every 12h for 3 doses as(More)
