Background & Objectives: Measurement of body Weight and height and determining of body mass index (BMI) according to age is one of the most important international indicators for evaluation of growth and physical health. The present study aimed to evaluate growth indices for schoolgirls 7-19 years of age living in Ardabil to compare with standard reference values and similar studies in Iran .
Methods: To assess the status of growth pattern of 7-19 year girls in Ardebil during 2005, with a descriptive cross-sectional study, 3996 healthy girls were selected by the multi stage sampling method and their age, body weight, height and body mass index were recorded, then 5,10,25,50,75,90,95 percentile, mean and standard deviation in different age were analyzed and compared with NCHS and selected regions of Iran
Results: The mean of Height and weight in urban girls is higher than their peers in rural regions. Height growth was more during the ages of 9-12 with its peakin 9 years olds with 6 cm annually. The highest increase in weight was at age13 which was estimated 5.5 kg annually. Mean of height and weight in girls of Ardabil is less than their peers in Tehran, Kerman, Esfahan but more than their peers in Zahedan. Of the height, weight and body mass index percentiles in girls of Ardabil aged 7-19 years were less than their American peers according to National Center for Health Statistics data.
Conclusion: All of percentiles anthropometric factors in girls Ardabil aged 7-19 years were less than NCHS standard.

Background and Objectives: Gastric cancer is the most incident disease in Iran that leads to death. This study was designed to evaluate the oxidative and antioxidative status in patients with gastric cancer by detecting paraoxonase 1 and arylesterase activities together with the level of malondialdehyde. The purpose of the present investigation was determination of Paraoxonase /Arylesterase activity and malondialdehyde (MDA) levels in the serum of patients with Gastric cancer.
Methods: In a case-control study, 20 subjects who diagnosed as gastric cancer individuals that referred to Ardabil Aras Clinic were selected from 2008 up to 2009. The case groups were matched with control group (30 subjects). Arylesterase and paraoxonase activities of paraoxonase-1 (PON-1), MDA levels and lipid profile were determined spectrophotometrically in serum of subjects.
Results: Upon matching of case and control groups, paraoxonase and arylesterase activities in patients with gastric cancer showed to be significantly lower than healthy subjects (190 ± 68.95 IU/L vs 258 ± 68.59 IU/L, 30.5 ± 28.4 U/L vs 284.23 ± 163.2 U/L respectively, P ≤ 0.001). Standardized activities of paraoxonase and arylesterase of case group were lower than controls (P ≤ 0.001). MDA levels have revealed significant increasing in cases than controls. In present study, HDL cholesterol and triglyceride levels were found to decrease in patient sera too, but the levels of total cholesterol and LDL cholesterol didn’t show to be different between two groups.
Conclusion: It was concluded that in patients with gastric cancer, oxidative stress was raised by attenuation of antioxidant system and oxidant levels rising.

Background & Objectives: Several evidences show that oxidative stress is high among patients with hemodialysis . This study was aimed to investigate the oxidative stress and serum level of zinc and copper in patients with non-diabetic hemodialysis .
Methods: In a case-control study, 60 patients with non-diabetic hemdialysis referred to hemodialysis section, Ardabil Bou-Ali hospital, and 60 healthy individuals, matched by age and sex, were selected. In each group, lipid profile, blood glucose, creatinine, urea, total protein, albumin, zinc, copper, malondialdehyde, total antioxidant capacity, activity of glutathione peroxidase and superoxide dismutase were measured. The results were analyzed statistically by using Pearson correlation coefficient and Student-t test.
Results: The amount of zinc, blood sugar, cholesterol, triglyceride, total protein, albumin, high density lipoprotein-C and low density lipoprotein-C were significantly lower in patients with hemodialysis in comparison with those in normal individuals. T he activity of superoxide dismutase, glutathione peroxidase in red blood cells and serum total antioxidant capacity were significantly high in patients in comparison with those in control group. However, serum concentrations of copper and malondialdehyde in two groups were not statistically different.
Conclusion : The results of this study show that increase of antioxidant enzymes activity reduces the oxidative stress status in patients with non-diabetic hemodialysis . Zinc deficiency was also observed in these patients.

Background & Objectives: The intake of antioxidant supplementations can have key role in prevention of oxidative stress in healthy individuals. Pomegranate has antioxidant effects and may play a role in reduction of oxidative stress in healthy males. Therefore, this study examined the effect of pomegranate juice supplementation on oxidative stress in young healthy males.
Methods : In semi-experimental study, 14 healthy students living in Dormitories of Ardabil University of Medical Sciences were included. Subjects were given one cup of pomegranate juice supplementation per day for two weeks . Fasting blood samples were taken both at the start and the end of 2-week period to measure the antioxidant enzyme activities such as superoxide dismutase , glutathione peroxidase , paraoxonase - 1, aryl esterase , and the values of serum total antioxidant capacity , glutathione, and lipid profiles . Data were analyzed using descriptive and paired t - test s.
Results: T he level of serum total antioxidant capacity and activities of enzymes such as superoxide dismutase, glutathione peroxidase, arylesterase, and standardized arylesterase activity were significantly increased at the end of two weeks (p<0.05). The serum level of malondialdehyde was significantly decreased after intervention (p<0.05). Changes were not significant, although the serum levels of glutathione and HDL- cholesterol increased and LDL- cholesterol decreased at the end of two weeks period.
Conclusion: The results of this study showed that the pomegranate juice supplementation had beneficial effects in helping body's antioxidant defense system and reduction of oxidative stress in young healthy males .

Background and Objectives : The risk of coronary artery disease increases with increasing of blood pressureboth in hypertensive and normotensive persons on the other hand nutritional factors have asignificant effect on blood pressure. The purpose of this study was to assess theeffect of caffeine on blood pressure in sedentary healthy male during resistance exercise.
Methods: In single-blind crossover study , twenty healthy and non-athlete male in the University of Mohaghegh Ardabili randomly selected and stratified according to age and BMI into twogroups: caffeine and placebo. The subjects performed repetitions to exhaustion at 60% of 1RM for any motion of chest press, leg press, squat and lat pulldown, 1 hour after taking caffeine (6 mg/kg body weight) or Placebo (similar dosage of starch). Blood pressure (BP) was measured before and 1 hour after taking caffeine and also immediately after any exercise. Data analysis was conducted using independent and paired t-test.
Results : Results indicated that systolic and diastolic BP and mean arterial pressure significantly elevated following caffeine intake at rest, but no significant differences were observed after exercise.
Conclusion: These findings indicate that caffeine at this dosage level alters cardiovascular dynamics by augmenting arterial blood pressure in moderately non-athletes male at rest. However, it seems that taking caffeine before resistance exercise does not cause abnormal elevations in blood pressure in sedentary healthy male.

Background & objectives: The most obvious indicators of a country's growth and development are technological capabilities and its scientific research . Therefore, any attempt to clarify the status of research and facing obstacles is important. The aim of this study is to investigate the problems and obstacles of knowledge from the viewpoint of faculty members of Ardabil University of Medical Sciences.
Methods: In a descriptive and survey study, sample contains 126 faculty members in Ardabil University of Medical Sciences were selected using Morgan and Krejcie table of sample size determination. The instrument used in this study was a questionnaire with two parts, i.e. demographic information and the Questionnaire of Research Barriers by Sotoodehasl et al. (2014) including 39 items on a 5 point Likert Scale continuum. A One-Sample T-Test, an independent samples T-Test, and an ANOVA test were used for the data analysis.
Results: The mean of the area of problems related to preparation of research project and development was 2.86 which is less than the conceptual mean but is not statistically significant (p=0.056). However in the other three areas, i.e. the means of problems in the implementation of the project, administrative and managerial problems, and individual problems were greater than the conceptual mean and the differences were statistically significant (p≤0.05). The mean of questions in the four areas was 3.23 which is greater than the conceptual mean and the difference is also significant (p=0.001).
Conclusion: In the investigation of areas, the most important problems and research barriers from the viewpoint of faculty members are weak teamwork at the university, large bulk of work and different expectations from the faculty members and lack of proper research environment.

Background & objectives: Iron overload is involved in the pathophysiology of many diseases including diabetes. In fact, the excess iron by creating free radicals makes damage to pancreas and leads to insulin resistance and diabetes. Andrographolide extract has hypoglycemic and antioxidant properties. This study has surveyed the effects of andrographolide on blood glucose and lipid profile in rats with secondary iron overload.
Methods: In this experimental study, 36 male Wistar rats were randomly divided into 6 groups: the healthy control group, secondary iron overload group, secondary iron overload groups treated with a dose of 3.5 and 7 mg/kg of andrographolide extract, and andrographolide groups treated with a dose of 3.5 and 7 mg/kg of extract. Iron and extract were injected for 6 and 12 days, respectively. Blood samples were taken for measurement of blood glucose and lipid profiles. Data were analyzed using ANOVA test.
Results: The pathological results of samples from liver of animals receiving iron showed that the iron was deposited in the liver tissues. Iron injection significantly increased blood glucose levels compared to healthy control group (p<0.05). In the iron overload group, andrographolide extract with a dose of 3.5 mg/kg or 7 mg/kg significantly decreased blood glucose levels (p<0.05). Iron injections did not increase the serum triglyceride and cholesterollevels. Injections of andrographolide extract with a dose of 3.5 mg/kg and 7 mg/kg, significantly decreased the cholesterol levels compared to iron receiving group (p<0.05).
Conclusion: Results of this study showed that the andrographolide with different doses may be effective in the treatment of diabetes by reducing serum glucose and cholesterol levels.

Background & objectives: The relationship between dietary patterns and esophageal cancer has not been documented yet. However, recent studies have shown that the Western dietary pattern is associated with an increased risk of esophageal cancer. The current study was performed a comparative evaluation of the food habits and serum nitrate level in patients with esophageal cancer and healthy individuals in Gorgan city.
Methods: In a case-control study, 44 patients with esophageal cancer (the case group) and 44 healthy subjects (control group) were selected for one year in Gorgan city. Anthropometric factors were measured, and then demographic and dietary data were recorded using general and food frequency questionnaires (FFQs), respectively. Fasting blood samples from both groups were collected to measure serum nitrate levels. Data were analyzed by independent t-test, Chi-square, Fisher, and Monte Carlo tests.
Results: the mean weight, body mass index (BMI) and serum nitrate levels were statistically lower in the case group than in control group (p<0.05). Salt intake, smoking cigarette or hookah was higher in patients than in control group (p<0.05). Based on nutritional habits , consumption of bread , rice, saturated fats, hot tea, sausages and industrial soft drinks was statistically higher in the patient group than control group, but intake of vegetables, fruits, unsaturated fats, honey and grilled meat was lower in patients than control group (p<0.05).
Conclusion: Consumption of fast foods, hot tea and saturated fats may be associated with esophageal cancer. Serum nitrate levels were lower in patients than control group, probably indicating the need for further research in this field.
