Abstract
Abstract Background and Objectives: Fluoride is one of the anions existed in water and soil. Its amount is not the same in different kind of water. Since the most of body's need to fluoride should be provided by drinking water, this study was aimed at determining the fluoride level in water supply of Gorgan rural regions. Materials and Methods: In this Cross-Sectional study, the subjects were all 67 water sources of the region. Every season, a one litter Sample was taken in a plastic Container and tested by SPADS Method. After Collecting and encoding the data, ANOVA was used to analyze. Results: The Findings shows that there are 4 springs and 63 wells which are Located in the mountainous (N=16) and flat (N= 47) regions. In every season, the average fluoride Level was lower than Standard Level (1.5 mg/L). The difference between fluoride Level of wells (0.39±0.15mg/L) and springs (0.16± 0.13mg/L) is Significant (p<0.05) the fluoride Level of mountainous wells is higher than wells located in flat regions (0.13mg/L). This deference was Significant (p<0.05). Conclusion: Based on The results revealing the fluoride Level of drinking water in Gorgan Rural region is less than international Standard, we recommend adding of Supplementary fluoride in foodstuffs of The people Living in This region. Key words: fluoride, drinking water resources, Gorgan, spring

Abstract
Background and objectives: Elevated blood lipids and physical inactivity are known risk factors of atherosclerosis. The objective of this study was to compare effects of four weeks of high-intensity intermittent training (HIIT) and continuous walking on atherogenic indices of obese middle-aged men.
Methods: Study population consisted of 36 male teachers aged 35-50 years, with mean body mass index (BMI) of 30.7 ± 3.5 kg/m2 who were working in the city of Galikesh, northeastern Iran. The subjects were enrolled via purposeful sampling and were randomly divided into two experimental groups and a control group. Before and after the intervention, anthropometric characteristics (height, weight and BMI) and blood pressure of each subject were measured. Fasting blood samples were taken from the left brachial vein 12 hours before the first exercise session and 12 hours after the last exercise session to determine lipid profile. Data were analyzed using SPSS 18 at significance level of 0.05.
Results: The four-week walking exercise significantly decreased serum levels of low-density lipoprotein-cholesterol (LDL-C) (P=0.001) and triglyceride (P=0.001). In addition, the HIIT program significantly increased high-density lipoprotein level (HDL-C) (P=0.004) and significantly reduced LDL-C (P=0.049), LDL/HDL (P=0.002), triglyceride (p=0.01), BMI (P=0.027) and blood pressure (P=0.002). In addition, the results of ANOVA and (Scheffe test) showed a significant increase in HDL-C (P=0.042) values and a significant decrease in VLDL-C (P=0.032), LDL/HDL (P=0.041), triglyceride (P=0.024), BMI (P=0.048) and blood pressure (P=0.016) of HIIT group compared to the control group.
Conclusion: Our findings indicated that HIIT has beneficial effects on some risk factors of atherosclerosis and cardiovascular disease.
