Background: The purpose of this study was to examine the effects of omega-3 supplement on pulmonary function of ranger troop volunteers who were taking part in classic training.Materials and methods: For this purpose 41 healthy ranger troop volunteers with age mean of 186±09 years, height mean of 169.9±9.2 cm, weight mean of 63.5±12.7 kg and BMI mean of 23.7±4.7 kg/m2 participated in this study. Subjects randomly divided into supplement and placebo groups. The both groups performed classic training 4-5 sessions per week for 8 weeks. Then each group was asked to consume 1000 mg/day omega-3 (for supplement group) or placebo (for placebo group) for 8 weeks. The pulmonary tests were measured before and after the study period.Results: Results indicated that combination of exercise and omega-3 consumption, significantly up-regulated pulmonary variables.Conclusion: Our study showed that consuming 1000 mg/d omega-3 in the courses of classic training induces positive changes in the lung volumes and capacities of ranger troop volunteers.

Background: The purpose of the current study was to determine the effect of personal and occupational environment on selective attention and executive function. For this reason we compared selective attention and executive function between the military forces and artists and ordinary people (non-military- non-artist).Materials and methods: In a descriptive analytical study 120 subjects were selected randomly from 3 groups. Data were collected by d2 test for evaluating selective attention and Tower Of London test for assessing executive function. Descriptive statistics, the ANOVA test, and Bonferroni multiple comparison tests were used for data analysis.Results: The results showed that the selective attention in military forces was higher than both artists and ordinary people. This discrepancy was statistically significant. Executive function, the same as selective attention had significant difference and it was higher in military forces in comparison with two other groups study Conclusion: It seems that these psychological characteristics fall under the influence of personal and occupational environment. The result of this study showed that military disciplines may have a relationship with improvement in selective attention and executive function status.

Background: Emotional intelligence contains awareness, regulation and expression of a wide scope of emotions. Therefore, the ability of recognizing and controlling of these emotions is an important aspect in emotional intelligence, and disability in each of these skills leads to disorders such as anxiety and mood disorders. So, we should teach the individuals these emotional intelligence skills to reduce the risk of disorders and improve their performance. The purpose of this study was to investigate the relationship between somatic symptoms, anxiety, depression and social function with emotional intelligence among the pilots.Materials and methods: In a cross - sectional study, 60 participants were selected by simple randomized sampling. They filled out two questionnaires: 1) GHQ-28, General Health Questionnaire; 2) Sharing Emotional Intelligence questionnaire. The data were collected and analyzed by Pearson's correlation and regression analysis.Results: The results showed a significant correlation between emotional intelligence and depression, anxiety, social function and physical symptoms (P<0.01). None of variables were the predictor factor of emotional intelligence.Conclusion: The study found that there is a significant relationship between emotional intelligence and psychological well-being and it may increase the mental health and performance with emotional intelligence training programs among the pilots.

Background: One of the most important parameters in reducing the army force function is the injuries which are caused by unallowable shoulder weapon recoil energy. The aim of this study was to investigate the effect of shooters’ body characteristics on shoulder weapon recoil injury and determine the optimal age range for minimizing these injuries.Materials and methods: In a descriptive-analytical study 15 soldiers of a garrison were selected voluntarily. They were asked to shoot 15 times a day and between each shot, they were questioned about the pain and recoil they had experienced.Results: Of the 15 volunteers, 14 demonstrated evidence of injury in the anterior shoulder (deltoid muscle). According to bruise definition, force is divided in two groups: the first one had minor injuries (40%) and the second had moderate injuries (60%). Three anthropometric variables were found to have predictive value on injury severity such as height, weight and dominant handgrip strength which were 177.29 cm, 80.36 kg, and 52.82 kg for the first group respectively and for the second one were 171.03 cm, 71.036 kg and 42.34 kg.Conclusion: Dominant handgrip strength was introduced as most effective parameter on recoil injury in human body characteristics.

Background: Fatigue is one of the most debilitating symptoms in patients with respiratory disorders. In addition, mental disorders have a high frequency among chronic pulmonary disease. This study was applied to assess the relationship between fatigue and mental health in chemical victims with bronchiolitis obliterans.Materials and methods: In this descriptive cross-sectional study, 93 chemical warfare victims with bronchiolitis obliterans were selected and referred to respiratory clinic of Baghiatallah Hospital. Fatigue and mental health was measured with fatigue severity scale (FSS) and general health questionnaire (GHQ-12).Results: The majority of patients (80.6%) suffered from severe fatigue. Of the patients, 77.4% had no desirable mental health. There was a significant relationship between fatigue and mental health (P<0.0001).Conclusion: Fatigue and poor mental health status in the study population suggested the necessity of paying more attention to these two variables for health promotion and improve quality of life in chemical warfare victims.

Background: This study aimed to assess the mental health status in partners of military personnel who were suffering from PTSD and had been referred to 505 Hospital.Materials and methods: In a case control study with a non-random sampling, 40 patients who met the inclusion criteria and 40 controls were selected. They were asked to fill in the GHQ-28. PTSD was diagnosed according to DSM-IV Results: Totally, 55% of cases and 27.5% of controls had general health problem with a statistically significant difference (P<0.05). There were also significant differences between two groups about somatic, anxious, depression, and social function (P<0.05).Conclusion: Our evaluation showed that general health in wives of military personnel with PTSD is lower in comparison with those without PTSD.

Background: Vaccination is one of the most efficient ways of prevention and immunization against infectious agents. This article aimed to review the importance of recombinant vaccines for immunizing against biological agents in army forces Materials and methods: This study was performed by searching through the internal and external websites and textbooks of military medicines Results: Killed or attenuated pathogens and inactivated toxins all are normally used for vaccination. But some complications have been seen due to existence of different antigens in their compound. On the other hand there are many new-found infectious agents we don’t have any efficient vaccine for them. For this reason it’s necessary to utilize the new technologies for recombinant vaccines.Conclusion: Various applications of recombinant vaccines not only in public health but also in military medicine play an important roles and development in this field can cause a great prosperity in personnel’s health status.
