Abstract
Background: Coronary heart disease is one of the most common causes of death in developed
countries. Fibrinogen and resistin are two inflammatory markers used for atherosclerosis risk prediction. The aim of this study was to examine the
effects of eight weeks of aerobic exercise on the concentrations of fibrinogen and resistin in healthy overweight middle-aged men.
Methods: Thirty inactive middle-aged men with a body mass index of 25-30
were randomly assigned into two experimental and control groups. The participants in the experimental group, accomplished eight weeks (3
sessions per week, of aerobic exercise with an intensity of 50-70% of their maximum heart rate while the control group remained sedentary. Weight,
body fat percentage, fibrinogen and resistin levels of the participants were measured 48 hours before the first and after the last training sessions. The obtained data were analyzed using Independent Samples T-tests.
Results: There were significant reductions in weight, body mass index, body fat percentage and fibrinogen and a significant elevation in resistin concentration in the experimental group (p<0.05) upon the
exercises relative to the control group.
Conclusion: It seems that eight weeks of regular aerobic exercise could reduce risks of
myocardial infarction and improve the health status of overweight middle-aged men through reduction of weight, body fat and fibrinogen and elevation of
resistin concentrations. Elevation of resistin concentration can be a sign of increased antioxidant defense mechanism.

Abstract
Background: Scoliosis is one of the most common spinal deformities with subsequent decrease in pulmonary function. The effects of surgical correction on the pulmonary function of patients with adolescent idiopathic scoliosis are controversial. The purpose of the present study was to compare the postoperative pulmonary function changes in different surgical approaches chosen for its correction.
Methods: Sixty-five patients with adolescent idiopathic scoliosis who had undergone corrective spinal surgery in Shafa Yahyaian Hospital since 1997 to 2007 and had documented preoperative pulmonary function test report, included in our study. The patients had documented preoperative pulmonary function tests and were divided into three groups based on their surgical approach. The first group was comprised of 25 patients who had undergone posterior spinal fusion (PSF), the second group included 29 patients who had anterior and posterior spinal fusion (ASF+PSF), and the third group consisted of 10 patients who had posterior spinal fusion and thoracoplasty (PSF+ thoracoplasty). The preoperative and the final follow-up values of absolute and percent predicted forced vital capacity (FVC) and forced expiratory volume in one second (FEV1) were compared and their relations with the undertaken surgical approach were evaluated.
Results: There were no significant correlations between the surgical approaches and changes in the pulmonary function tests (P>0.05). FVC and FEV1 values were similar to preoperative values in all groups after a minimum follow-up of two years.
Conclusion: There were no significant differences between different surgical approaches for adolescent idiopathic scoliosis regarding the pulmonary function test results after at least two years of follow-up.

Abstract
Background: Studies indicate that obestatin, an anti-hunger peptide, plays an important role in energy balance, GH secretion, and body weight. It has been physiologically shown that obestatin apposes the function of Ghrelin. The purpose of the present study was to investigate the effects of a single session of aerobic exercise in trained women (a 1.5-mile run) on the expression of obestatin gene found in lymphocytes.
Methods: 16 trained female participants (4±1 years of training experience) were voluntarily selected from Khorasan province in Iran and were randomly divided into two groups: the control and aerobic exercise groups. The participants in the aerobic group were asked to run for 1.5 miles with a fixed speed (70 VO2 max) while the controls were passively present in the exercise environment. Following an overnight fast, blood samples (10 ml from the antecubital vein) were collected before and immediately after the exercise from all the participants. Obestatin expression was investigated after separating the lymphocytes by centrifuge and using semi-quantitative RT-PCR.
Results: There was a rise in obestatin gene expression in the case group after one session of aerobic training versus the control group but the changes were not statistically significant.
Conclusion: The results indicated that a single aerobic exercise could not significantly increase the expression of obestatin. Perhaps the type, duration and intensity of the applied protocol in this study did not have a cumulative effect on this gene although these results are in harmony with the results of other studies in this regard.
