Background and Objective: Ghrelin is an acylated 28-amino-acid peptide that is the most recently identified adipocytokines, but its role in diabetes is poorly clarified. The objective of this study was to determine the relation between serum ghrelin and blood glucose levels in type 2 diabetic obese males.

Materials and Methods: This descriptive study was done on 45 adult obese males with type-2 diabetes in Saveh city, Iran during 2010. Fasting blood glucose, insulin and ghrelin concentrations and Glycosylated hemoglobin HbA1C were measured after overnight fasting. Multiple regression was used for determine ghrelin in relation to glucose, insulin and HbA1C.

Results: The multiple regression analyses revealed that HbA1C is not correlated with serum ghrelin levels, while, fasting blood glucose level had positive corrolation with serum ghrelin concentration (P<0.05). Serum ghrelin level had high negative correlation with insulin (P<0.05).

Conclusion: This study indicated that elevated endogenous ghrelin led to hyperglycemia. Therefore, serum ghrelin is a precise index of blood glucose level in obese male patients with type-2 diabetes.

Background and Objective: Accumulating evidence indicates a relation between aerobic capacity and glucose concentration, although the molecular mechanisms of this relationship are not fully known yet. This study was done to determine the effect of effect of 12 weeks aerobic exercise training on aerobic capacity and glucose concentration in obese men. Methods: In this quasi-experimental study, thirty two adult obese males were divided into interventional and control groups. Anthropometrical indexes, fasting blood glucose and insulin, resting heart rate and aerobic capacity (VO2max) were measured before and after a 12 weeks aerobic exercise in the interventional and control groups. Beta cell function was calculated by fasting glucose and insulin. Results: Long time aerobic exercise led to significant reduction in glucose (112±10 vs. 85±11 mg/dl), anthropometrical indces, BMI (28.44±2.29 vs. 33.24±5.14), increase in VO2max (26.12±4.11 vs. 32±6.41 ml/kg/min), beta cell function (83±23 vs. 181±35) and in interventional group in comparision with controls. A significant correlation was found between the changes in VO2max with changes in beta cell function and glucose level, these correlations were independent of BMI. There was no significant change in insulin level between intervention and control groups. Conclusion: Increased aerobic capacity or cardiovascular fitness by exercise training improve beta cell function of glucose concentration in obese men.

Background and Objective: Cardiovascular diseases are the main cause of 50% of death in women after menopause. This study was done to evaluate the effect of combined training on cystatin C, high- sensitivity C-reactive protein and some cardiovascular risk factors in sedentary postmenopausal women.

Methods: In this quasi -experimental study, 24 sedentary postmenopausal women (50-65 years) were non-randomly divided into experimental and control groups. Women in the experimental group were received a combined training program including aerobic exercise (65-75% of MHR) and resistance exercise (55-65% of 1RM), 4 d/wk for 10 weeks. The control group did not participate in any physical activity. Body weight, BMI, BF%, blood pressure, levels of cystatin C, C-reactive protein, triglyceride, HDL-C and LDL-C were measured before and after study.

Results: Exercise training showed no significant effect on serum levels of cystatin C, C-reactive protein and cardiovascular risk factors such as HDL-C, LDL-C, triglyceride and blood pressure in postmenopausal women.

Conclusion: Short-term combined training with moderate intensity has no effect on cystatin C levels and other cardiovascular risk factors in sedentary postmenopausal women.

Background and Objective: New markers of cardiovascular disease have more sensitivity and accuracy in predicting cardiovascular events. Considering the effective role of physical activity in preventing and reducing cardiovascular disease, which will be of great help in improving the health of people in the community. This study was done to determine the effect of diving in different depths on the level of C-reactive protein (CRP) and lipid profiles of diver men.
Methods: This quasi-experimental study was carried out on 6 male diver members of the rescue and rescue team of the Red Crescent Society of Kohkiluyeh and Boyer Ahmad province in Iran. Subjects diverted on the first day at a depth of 1 meter, the second day at a depth of 10 meter, and the third day at a depth of 20 meter for 40 minutes. The subjects were at a depth of 10 and 20 meters at a height of 3 meters to the surface of the water for five-minute steepness. Blood samples were taken before and after diving, and CRP and lipid profiles including triglyceride, total cholesterol, low density lipoprotein and high density lipoprotein were measured.
Results: The increase of environmental stress caused by diving in three depths of 1, 10 and 20 meters of the sea  significantly increased CRP level (P<0.05). No significant changes were observed in the levels of triglyceride, total cholesterol, and low density lipoprotein, but high density lipoprotein level was significantly increased (P<0.05).
Conclusion: Scuba diving, due to the transport of respiratory equipment during activity increases
C-reactive protein and lipid profiles.

Background and Objective: Trauma is the third cause of death and the main cause of disability in Iran. Children are more susceptible to trauma due to physiological conditions and the growth process. This study was done to evaluate the epidemiolog of pediatric trauma in Hamedan, Iran during 2016-2017.

Methods: This descriptive-analytical study was done on 482 traumatic children (330 boys, 152 girls) at the age of 0 to 14 years whom referred to Besat Hospital in Hamedan, Iran during April 2016 to March 2017. Age, gender, season, type of troma and the outcome of trouma were recorded for each subject.

Results: The highest rate of trauma was observed between the ages of 7-14 years old (40.5%). The rate of trauma was significantly higher in boys than the girls (P<0.05). The most rate of trauma occured in summer (36.9%). The most common, place, cause, type, region of traumas were home (44%), falling down (53%), fracture (35%), and region (41%) respectively. Regarding the subsequence of discharge of subjects, 10 deaths and 42 disabilities after trauma were observed.

Conclusion: Regarding the most common type and place of accidents, providing safety at home and knowledge of parents are nesscery for preventing of pediatric teruma in Iran.
