Abstract

ABSTRACT
          Background and Objectives: The incidence rate of esophageal cancer (EC) is high in north and northeast of Iran. Taurine is a sulfur-containing amino acid with a wide range of vital biological functions. The aim of this study was to compare plasma levels of taurine between patients with EC and healthy controls.
        Methods: Plasma samples from 36 recently diagnosed cases of EC and 36 healthy adults were analyzed by high-pressure liquid chromatography. Data analysis was done using SPSS (version 16). The t-test was used to evaluate significant differences in the level of taurine between the two groups. P-values less than 0.05 were considered statistically significant.
         Results: Patients with EC had significantly higher levels of plasma taurine compared with the controls (P<0.05).
         Conclusion: Patients with EC have significantly higher levels of plasma taurine compared with healthy individuals. This finding suggests that the measurement of plasma taurine in patients with EC could be useful for the early diagnosis of the disease.

Abstract

Background and objectives: Endurance exercise causes fatigue due to mitochondrial dysfunction and oxidative stress. The present study was designed to investigate the effects of taurine supplementation on lipids peroxidation and antioxidant activity during endurance activities. 
Methods: Twenty-four male volunteers aged 27 ± 1.8 years and weighting 74.9 ± 5.9 kg were randomly divided into three groups: taurine supplementation (n=8), placebo (n=8), and control (n=8). The subjects completed a 28-day endurance training protocol. Biochemical parameters such as superoxide dismutase (SOD), glutathione peroxidase (GPX) activities, as well as malondialdehyde (MDA) concentrations (8 hours before the first session and 8 hours after the last session) and maximum rate of oxygen consumption, were measured to evaluate the antioxidant, lipid peroxidation, and VO2 max status respectively. Finally, data were analyzed by SPSS software at a significance level of <0.05.
Results: Taurine supplementation significantly increased SOD (p=0.001) and GPX (p=0.001) but significantly decreased MDA (p=0.001). However, it had no significant effect on the VO2 max. 
Conclusion: The results of the present study indicate that taurine has antioxidant effects against endurance exercise-induced oxidant stress and lipid peroxidation.
