Abstract
With industrial and economic growth and production of different compounds and chemical materials which human being has gained using natural resources for his ease and comfort , in turn , he introduces matters such as heavy metals and toxic agents into the nature , an unwanted process which leads to serious problems and dangers either for environment or for himself. This study aims at determination of heavy metals concentration (As,Pb,Cd,Cr,Hg and Zn) in water resources and wells of Aleshtar during 4 seasons in the year 2009.
Materials and Methods :This cross- sectional study was carried out to determine concentration of heavy metals including As, Pb,Cd, Cr, Hg, Zn in Aleshtar drinking water resources. twenty samples from five drinking water wells were systematiclly collected and carried to water lab. By use of express standard methods,samples were 10 times concentrated, then metals concentralion determined by AAP(WFX130) and data analyzed by SPSS and EXCELL soft wares.
Results: The results showed that concentration average of Hg ,Zn and Cd was zero during the sampling and concentration average of As,Pb and Cr in drinking water wells were 0.0033, 0.0788 and 0.01 mg/l respectively.
Conclusion: Findings indicated that concentration average of heavy metals in all studied drinking water wells were lower than standard limit and no significant difference was observed during 4 stages of sampling , consequently ,drinking water of the mentioned wells are not polluted to the heavy metals.

Abstract
Systemic inflammation is associated with reduced lung function in obese individuals. Whether aerobic training in obese subjects is associated with improvement in systemic inflammation and lung function is unclear. The aim of this study was to evaluate the effects of a 12 week aerobic training on C- reactive protein and lung function in obese men.
Materials and Methods: Twenty-three obese subjects (age: 46.19±3.9 yr, body mass index (BMI): 31.64±0.87 kg/m2) were randomly divided into aerobic training (n=12) and control (n=11) groups. A matched control group of normal weight participants (n=9) were also recruited for baseline comparison (age: 45.36±4.1 yr, BMI: 24.63±0.45 kg/m2). Aerobic training was performed 3 times weekly for 12 weeks. Body composition (computed tomography), inflammatory parameter, and pulmonary function were measured prior to and after the intervention.
Results: At baseline, obese individuals had higher serum C-reactive protein and poor pulmonary function than normal weight participants (p<0.05). After a 12 week aerobic training, body weight, waist circumference, visceral fat, total abdominal fat, and C- reactive protein were significantly decreased (p<0.05). In contrast, lung function parameters were improved after the aerobic training (p<0.05). Conclusion: Aerobic training resulted in an improvement in obesity indices and lung function in obese men, and this improvement was accompanied by decreased C- reactive protein levels.

Abstract
Background: Medicinal smoke has been in natural health products by many nations all over the worlds. Dung's smoke called "Anbar Nasara" is one of the most used medicinal smokes in Iranian traditional medicine. Anber Nasara has been administered as inhalation in the treatment of viral or bacterial infections as well as for tumors and cysts in vaginal diseases in women. Its cytotoxic effects have been proposed in these studies. Materials and Methods: Dung's of female donkey have been collected from Shahreza, Isfahan province in summer 2011. The samples were burned in a specially designed apparatus and its smoke was collected in n-hexane solvent over ice-cold water. Solvent was evaporated in the air and dried residue was dissolved in DMSO and diluted in RPMI So that the final concentrations of 0.4, 0.3, 0.25, 0.2, 0.125, 0.1, 0.0625, 0.0312 mg/ml were obtained for MTT assay as a cytotoxic evaluation method against two cancer cells (KB and Hela) and a normal one (L929). After 48h incubation percent cell survival and IC50 values were obtained using ELISA plate reader at 540nm. Results: Results showed that dung's smoke were cytotoxic in tested concentrations against cancer cell lines in a dose dependent manner. The IC50 was calculated ≥ 0.2 mg/ml. Conclusion: Dung's smoke consists of too many constituents and its cytotoxic effect may belong to one or complexes of constituents. More researches are under way to clarify these aspects of the study.

Abstract
Background: Considering the importance of content and citation analysis in understanding the needs and improving journals’ scientific quality, the objective of the present study was to content and citation analysis of published articles in Lorestan University of Medical Sciences Journal (Yafte) during 2011 to 2015.
Materials and Methods: This study is a prospective longitudinal study conducted in 2016. Published articles during 2011 to 2015 were studied. Data were collected by a researcher-made checklist and analyzed by SPSS version 21 and descriptive statistics.
Results: Results showed that 95.8 percent of the articles were original and most of organizational affiliations of authors were related to Lorestan University of Medical Sciences (53.8). Over the past five years, 262 articles have been published in the Yafte Journal, half-life of resources were 8.38 years and the highest number of articles were published in the years 2013 and 2012.
Conclusion: Considering the results of this study, it is suggested that the journal authorities should take necessary steps to balance organizational affiliations of published articles. It is also suggested that authors should be encouraged to use newer sources by setting some restrictions.

Abstract
Background : Cellular phones can cause some inappropriate consequences, in addition to having wide applications. Due to the growing popularity of this technology among students, the current study aimed to determine the level of dependency on the cellular phone and its relationship with the academic performance of students of Lorestan University of Medical Sciences.
Materials and Methods: This descriptive-analysis study was conducted on students of the faculties of Paramedicine, Health and Nutrition at Lorestan University of Medical Sciences in the first semester of 2015-2016. Stratified random sampling was used. Data were collected using a Cellular Phone Dependency Questionnaire (CPDQ), the psychometrics properties of which had been approved. Data analysis was conducted with SPSS software and independent t-test, Pearson correlation coefficient, ANOVA and Duncan's post hoc tests.
Results: The mean of cellular phone dependence score of students was 40.61 ± 8.08, which was at the average level. The findings of the study showed that 24.7 percent of participants had a weak dependency level, 51.3 percent were average, and 24 percent had a strong level. Furthermore, there was a significant inverse relationship between the cellular phone dependence score and the previous semester's grade point average (r = -0.19, p = 0.03) and overall grade point average (r = -0.2, p = 0.006).
Conclusion: The findings of the study showed that cellular phone dependency causes a reduction in academic performance. Considering the increasing spread of cellular phones among students, performing of planning and controls is essential to prevent its negative consequences.

Abstract
Background: Exercise is a therapeutic procedure for addicts; however, its physiological mechanisms are not well understood. This study aimed to investigate the effect of eight weeks of endurance training on the levels of vascular endothelial growth factor and endostatin in the heart tissue of male rats with morphine withdrawal syndrome.
Materials and Methods: This experimental study was conducted on 32 male rats randomly divided into four groups of eight: healthy control (HC), endurance training (ET), morphine control (CM), and morphine+endurance training (M.ET). Two morphine withdrawal groups were addicted to 0.4 mg/ml morphine sulfate for 21 days. The exercise groups performed eight weeks of treadmill running. At the end of the study, all rats were killed, and their heart tissue was removed. Protein levels of the indicators in this study were measured by ELISA kits. The data were analyzed by Tukey’s one-way ANOVA test.
Results: The results of this study showed a significant decrease in VEGF levels (P<0.001) and a significant increase in ES (P<0.001) in the MC, compared to the HC. In addition, the increase in VEGF levels (P=0.014) and the decrease in ES (P=0.026) in the M.ET showed a significant difference, compared to the MC.
Conclusion: Endurance training may be useful in preventing negative changes in angiogenesis and metabolic parameters related to morphine, which should be considered in the rehabilitation of addicts.
