Abstract

  Background &Objectives: According to a recent report published by the Ministry of Health in Iran gastric cancer is the most common cause of death due to cancer in this country and cardiac cancer is the most common kind of upper GI cancer. This study is an attempt to determine the epidemiology of cardiac cancers in Ardabil.

  Methods: This descriptive cross-sectional study was conducted for four years (2000-2003) at the only private clinic in Ardabil. The results of endoscopy of these patients including the exact determination of the topography of cancer in cardia and other general information were recorded. The data were analyzed using SPSS software (version-10)

  Results: During this study 4356 endoscopy were done and 533 histologically proven upper GI cancer were detected. Out of 533, 242 cases were located at E-G junction area, 82(33.9%), 130 (53.7%) in cardia region and 30(12/4%) cases were located at the proximal bady of stomach. 130(53.7%) cases of tumors were, in the right side of cardia. Bormann classification showed that most of cancers (43.8%) were ulceroinfiltrative.

  Conclusion: Statistical analysis indicated that there is a significant relationship between type and topography of cancer with dysphasia, weight loss and epigasteric pain(p<0.05). The results showed significiant relationship between type and topography of cacers with Bormann classification(p=0.001). Further epidemiologic studies are required to evaluate etiology of cardia cancers in Ardabil.

Abstract

  Background & objectives: The “redox” state represents the oxidation/reduction potential within the cell in a way that more “redox” is the marker of health, while the more oxidized reflects predisposition to diseases. Different types of exercise training may change the thiol/disulfide ratio of redox couples such as glutathione and represent a shift in redox balance. This study was assessed the influence of high-intensity aerobic exercise on glutathione redox state in red blood cells in professional, recreational athletes and nonathletes.

  Methods: Ten voluntary well trained (WT), moderately trained (MT) and untrained men subjectswere randomly selected for this semi-experimental study (mean ages of 21.10±1.72 21.70±1.88 and 20.10±1.44, respectively). Blood samples were collected before, immediately, 10 min and 30 min after acute aerobic exercise with 75%VO2max. The levels of reduced glutathione (GSH), oxidized glutathione (GSSG) and (GSH/GSSG) in red blood cells (RBCs) as well as serum levels of cortisol and creatine kinase (CK) were measured.

  Results: The results showed reduction, elevation and no changes in RBCs GSH/GSSG ratio in UT, MT and WT groups, respectively. The lowest levels of GSH/GSSG ratio in RBCs and the highest one were detected in the WT and MT groups, respectively. The serum levels of cortisol and creatine kinase were increased following the exercise in three groups.

  Conclusion: It is concluded that acute aerobic exercise with high intensity does not change redox balance in well trained subjects, however it is capable to shift redox balance towards more reducing environment in moderately trained subjects and also to more oxidizing one in untrained subjects.

Abstract

Background & objectives: Non-alcoholic fatty liver disease (NAFLD) is the most common chronic liver disease in the world which is associated with cardiovascular disease. The aim of this study was to investigate the plasma changes of chemerin and pentraxin-3 (PTX3) following 8 weeks of endurance training in men with NAFLD.
Methods: In this quasi-experimental Study, thirty four patients with NAFLD were selected purposefully. The participants were randomly divided into two groups, endurance training group (n=17) and control group (n=17). The endurance training program included eight weeks running on a treadmill with maximum heart rate (HRmax) intensity of 55-75% for 45 minutes three times a week. Seventy two hours before the beginning of the study and at the end of the eighth week, blood samples were taken from all the participants. The data were analyzed by paired sample t-test and independent t-test at the significant level p<0.05.
Results: Plasma levels of chemerin in the endurance training group significantly decreased (p=0.013). Also, there was a significant difference between the two groups after the end of the intervention (p=0.002). Plasma levels of PTX3 increased significantly in the endurance training group (p=0.001). There was also a significant difference between two groups after the end of the intervention (p=0.01).
Conclusion: The present study showed that the 8-week endurance training increased the plasma levels of PTX3 and decreased the plasma levels of chemerin in men with NAFLD. Endurance training, possibly through various mechanisms, reduces the inflammatory factors and increases the anti-inflammatory factors in men with NAFLD. Endurance training, probably by activation of lipolysis, over-regulation of unpaired protein-1 and activator receptors of peroxisomes proliferation-, changes in adipocytokines, etc. decreases charmicin and increases PTX3 levels of plasma in men with NAFLD.
