Background and Objectives: Nowadays the use of herbal plants due to their low complications attracts the mind of many scientists. The aim of this study is the assessment of the Naloxone as an antagonist of opioids on seizure duration time induced by PTZ and determine the anticonvulsant mechanism of hydro alcoholic extract of Scrophularia striata Boiss. Materials & Methods: In the present study, 40 male mice were randomly divided into five groups of eight; The control group (receiving PTZ 80 mg/kg, i.p.), Two treatment groups (Scrophularia striata 600 and 900 mg/kg, i.p.) and two experimental groups (Scrophularia striata 600 and 900 mg/kg i.p plus Naloxone 5 mg/kg, i.p., 5 minutes before extract injection). With injection of PTZ, convulsive behaviors in mice during 20 minutes were recorded by camera and the various stages of seizures were evaluated. Statistical data were analyzed using with the tests of one way Variance and Tukey in SPSS 16. PResults: Statistical analysis showed that Naloxone injection with extract administration have slightly and not significantly decreased the latency time to tonic and clonic seizure in comparison with the control group. Latency time to tonic-colonic has been increased in extract only group and extract associated Naloxone group. With injection of the extract alone total seizure time has decreased but in extract associated Naloxone group this time has increased that this increasing in dose of 600 mg/kg is significant in comparison with control group (P<0.01). Data showed that extract injection lonely and associated with Naloxone have increased the duration time of tonic seizure, duration time of tonic-colonic with extract injection was increased but this time in Naloxone group has been slightly decreased. Conclusion: Our study indicated that Naloxone as an antagonist can inhibit the anticonvulsant activity of hydro alcoholic extract of Scrophularia striata Boiss.

Background & Objectives: Epidemiological studies of diet and asthma have focused on intakes of individual nutrients and foods and few studies have examined associations with dietary patterns. The aim of this study was to determine dietary patterns in patients with asthma. Materials & Methods: A case–control study of 47 cases with asthma and 47 healthy controls aged between 18 and 50 in Ahvaz, Iran, was carried out. Demographic and anthropometric data were collected by personal questionnaire. Information about usual diet was obtained by semi-quantitative food frequency questionnaire. Independent sample t-test was used to compare variables. Results: No significant differences were observed in anthropometric indices and dietary intakes of energy and macronutrients between groups. The meat and alternatives food group consumed less in asthmatic patients compared to healthy controls (P=0.032), but no significant differences were shown in the consumption of other main food groups. The processed meats, fast foods and salty foods were consumed less in the case group but the consumption of hydrogenated oils was significantly higher in this group (P<0.05). Conclusion: It seems the decreased consumption of fast foods and the compliance of dietary regimen in order to control the asthma symptoms or attacks resulted in following healthier dietary pattern in patients. Future studies with larger sample size and biochemical assays are suggested.

Background & Objectives: As a result of an increase in using of computers in the occupational environments, the prevalence of musculoskeletal disorders (MSDs) has increased in these types of occupations. These musculoskeletal disorders also Imposes heavy financial consequences on health care systems. The aim of the present study is to evaluate the relationship between psychosocial factors and the prevalence of musculoskeletal discomfort in VDT workers. Methods: This cross-sectional study was carried out in three cities covered by one directs of the Iranian Gas Transmission Operation during 2011 and 2012 years. In this study, all of 300 office workers in this region participated. The investigation consisted of two questionnaires, first standardized Nordic questionnaires to measure the prevalence of disorder, second ALL EMPLOEE SURVEY questionnaire to measure psychosocial factors. Statistical analyses were performed by the Statistical Package for the Social Sciences software (SPSS version 16.0). The Statistical methods used in this study include chi-square and logistic regression. Results: The mean age and work experience of the subjects were 7.00 ± 59.34 and 71.6 ± 56.9, respectively. The highest prevalence rate of disorder was found in the Lower back (49.7%) and neck (49.0%) regions. Results of the multiple logistic regression models show that psychosocial like work / family balance, job control, leadership, resources , customer service , co-worker support , reward , cooperation, employee development and job demands, and the individual factors like sex, BMI and education level were independently associated with prevalence of musculoskeletal disorders (p<0.5). Conclusion: The results of the study indicated that some psychosocial factors are related to prevalence of musculoskeletal disorders. Consequently, in order to prevent or reduce musculoskeletal disorders, these factors must be considered.

Background: Decellularised tissues matrix is considered as an ultimate scaffolding system for two reasons: firstly it has mechanical and structural similarity with natural tissue, secondly extra cellular matrix proteins remain intact after decellularization, which are important for cell differentiation. The aim of this study is investigation behavior rat adherent bone marrow cells cultured in decellularised matrix of human skin. Materials and Methods: In this study, human skin tissues were decellularised by three methods: physical (slow freezing and snap freeze–thaw), enzymatic (trypsin 0.25%, 18 hours) and chemical (sodium dodecyl sulfate- SDS 1%, 12 hours). After washing and sterilization procedures, scaffolds cultivated with 4×10⁵ rat adherent bone marrow cells. Finally, histological studies were performed after 1, 2, 3 and 4 weeks of culture and investigated with different staining. Results: Histological study of decellularised scaffolds revealed that nuclear and cellular components of the tissues were completely removed and collagen fibers remained intact. At 1, 2, 3 and 4 weeks of culture, in vitro analysis showed adhesion and also proliferation of rat adherent bone marrow cells. Also, we did not observe any penetration and migration of the cells into scaffolds. Statistical analysis indicated significant difference in percentage of cell density in specimens cultured after 2 weeks versus the other specimens (P<0.001). Conclusion: the overall results showed that remnant ECM (Extracellular Matrix) of human skin can be a suitable scaffold for studying Rat Adherent Bone Marrow Cells behavior.

Background & Purpose: Volatile organic compounds (VOCs) significantly affect the chemistry of atmosphere and human health and petroleum storage has been identified as largest emitters of VOCs. With models of air pollution can model the concentration and distribution of VOCs from oil tanks. The aim of this study was to investigate and model of VOCs emissions from an oil tanks field in Iran using the TANKs 4.0.9d software and the distribution of these compounds in the study area using AERMOD model. Materials & Methods: In this study, the rate and percentage of monthly emissions of VOCs from 22 oil storage tanks in 12 months year 2014(1392-1393) using the TANKS software were determined according to losses and tank type in Esfahan, Iran. Then, by using AERMOD model the maximum concentration of VOCs in the area with the surface of 10 × 10 km2 and with a network distance of 200m and then in the range of 50 × 50 km2 and with a network of 1000 m in the statistic period of 12 months and for a average time of 1, 3, 8 and 24 hours, one-month and one -year statistical period at the height of 1.5m of the Earth's surface was determined and the distribution of VOCs in the area was simulated and displayed by GIS software. Results: The results of TANKS software showed that the studied tanks were annually emitted 1485801.26 tons VOCs in which the tanks with external floating roof 99.98% and with fixed vertical roof 0.017% were contributed. The results of AERMOD software also indicated that maximum concentrations of VOCs occur in the area 10×10 km2 in cold seasons. This phenomenon is due to reduce of mixing depth and resulting in the formation of the inversion phenomenon. Conclusions: This work can help plant engineers to decide on an appropriate strategy to control VOCs. Employing the tanks with fixed vertical roof and modification of operational pattern could lead to a reduction of VOCs emissions and eventually affect the economical, ecological and hygienic aspects.

Background & Objectives: Considering the prevalence of cigarette and hookah smoking among adolescents and the need to identify the components and dimensions of such behaviors, this study was conducted to determine the predictors of smoking cigarette and hookah among students due to designing appropriate and effective interventions. Materials and Methods: Using a cluster random sampling method, 201 male students were selected from highschool in Najaf Abad city, Isfahan. The selected students were evaluated by the revised risk and protective factors of drug use questionnaire. Data were analyzed using Pearson correlation coefficient and multiple regression analyses. Results: The results of correlation coefficient showed that there was significant positive correlation between cigarette smokings in the lifetime and all 12 components risk profile. Also, drug use and hookah smoking in the lifetime were related with hopelessness, social skills, sensation seeking, parental attitudes to drug use, monitoring, family and sense of commitment to school. The results of stepwise regression analysis showed that components of attitudes to drug use, parental attitudes to drug use and impulsivity predictive variance explain the 55 percent of cigarette smoking. Also, attitudes toward drug use and sensation seeking pridicted 19 percent of variance of the hookah smoking, and attitudes toward drug use, social skills, family conflict and parental attitudes to drug use pridicted 17 percent of variance of tend to cigarette smoking and, finally, attitudes toward drug use, family monitoring and chaotic social environment pridicted 19 percent of variance of tend to hookah smoking. Conclusion: According to the results, one can say that the prevalence of hookah and cigarette smoking in adolescents are increasing and the starting age is decreasing. The hookah and cigarette smoking by adolescents is a multi-factor and multi-level phenomenon, and the major factors for their determining exist at multiple levels of individual, social and family, which should be considered for intervention, prevention, an control of cigarette and hookah.

Background and purpose: Low frequency stimulation (LFS) has anticonvulsant effect. However, its mechanism of action has not been completely determined. In the present study the effect of LFS on evoked inhibitory post synaptic GABAergic currents (eIPSC) is investigated in CA1 pyramidal neurons of the hippocampus in kindled rats. Materials and Methods: In this experimental study animals were kindled through electrical stimulation of amygdala. 24 hours following fully kindling achievement in 20 Wistar rats, the effect of LFS on eIPSCs was assessed in hippocampal slices. Results: Obtained results showed that application of LFS at 200 pulses and at the intensity of 1.5 threshold, increased the amplitude and decay time constant of eIPSCs in both control and kindled rats. When 200 pulses of LFS were administered with an intensity equal to threshold, only eIPSC amplitude was increased in both control and kindled groups significantly (P<0.001). Comparing the effectiveness of LFS on control and kindled groups showed that 200 pulses of LFS at the intensity of 1.5 threshold had higher effect in control than kindled group (P<0.001). Conclusion: Results of the present study showed that LFS application increased eIPSCs parameters in a pulse number and intensity dependent manner. This increment can be considered as a possible anticonvulsant mechanism of LFS.

Background & Objectives: The importance of omega-3 fatty acids as dietary supplements and its anti-inflammatory effects have been identified, so this study was aimed at determining the effects of omega-3 fatty acids supplementation and six weeks anaerobic exercise on changes in plasma levels of PGE2, CK, and LDH among active women. Methods: This study was a semi-experimental method with successive measurements. For the mentioned purpose, 32 healthy and active students (mean age of 22.41 ± 0.3 years, mean height 162.77± 2.1 cm, average weight 58.06± 2.0 kg and mean body mass index of 22.01±2.0 kg/m2) were randomly divided into 4 groups: control, supplements, exercise, exercise-supplementsand were studied for six weeks. ANOVA, Bonferroni test were used for statistical analysis and spectophotometry method was used for blood markers analysis. Results: The results showed that six weeks of aerobic exercise significantly increased CK and LDH and PGE2 (P=0.001) while these parameters were decreased in the exercise-supplementsgroup, although the reduction rates were not significant. The level of mentioned indices significantly decreased in the group that received only omega-3 (PGE2: P=0.05 and CK: P=0.034). Conclusion: According to achieved results; it can be deduced that CK, LDH and PGE2 levels increase during six weeks of aerobic exercise among active women. On the other hand, if omega3 supplements be taken during anaerobic exercises, the level of mentioned parameter will decrease.

Background & Objectives: Hot working conditions are common in open-pit mines where workers are exposed to heat stress. Investigating the hot working environments may lead to preventing diseases caused by thermal stress in mines. The aim of this study was to evaluate the relationship between WBGT thermal stress index and physiological parameters in the iron ore miners. Methods: The present descriptive study was conducted on 120 healthy men in the summer season. Tympanic and skin temperatures were measured using a FT70 model thermometer manufactured by Beurer Co, Germany. Heart rate and blood pressure were measured using Emsig BO26 model (Taiwan) digital instrumentation. All environmental and physiological parameters were simultaneously measured and recorded. The WBGT index was calculated using the formula. Finally, the correlations were evaluated using linear regression and Pearson's correlation. Results: The statistically significant correlation between WBGT heat stress index and physiological parameters was found. The Pearson's correlations between WBGT index and tympanic temperature, skin temperature, heart rate, systolic and diastolic blood pressure were 0.592, 0.557, 0.624, 0.486 and 0.419, respectively. Conclusion: WBGT index showed a high correlation with physiological parameters, including tympanic temperature, skin temperature, heart rate, systolic and diastolic blood pressure, and had the highest correlation with heart rate. WBGT index has an acceptable correlation with physiological parameters of Workers in open pit mines and can be a suitable index to evaluate thermal stress in such working environments.

Background & Objectives: Vertebroplasty is a new and effective treatment for strengthening broken vertebra and reducing the pain arisen from osteoporotic fractures. This study was performed to determine the pain reduction effect of percutaneous vertebroplasty with calcium phosphate in traumatic vertebral fractures in patients attending to Laleh, Mehrad and Booali Hospitals in 2012. Materials & Methods: In this quasi-experimental study, 18 patients with traumatic fractures in Laleh, Mehrdad and Bu Ali hospitals were studied during the year 2012. The method of purposeful non-probability sampling was used and ethical issues were carefully considered. Pain intensity were determined and compared based on Visual Analog Scale in 3 phases; before and immediately after percutaneous surgery and vertebroplasty with calcium carbonate, and 6 months later. The data were analyzed using SPSS software and descriptive statistic method. Results: In this study, at first, the mean preoperative VAS was 8.2 that, subsequently, decreased to 1.68 and zero. Comparison of preoperative and postoperative pain severities demonstrated that 79.6% reduction was observed in the pain and later this amount was increased to 100%. Overly, there was not a relationship between changes in VAS and variables such as leakage in patients, age, calcium carbonate amount, gender and level of involvement. Conclusions: It may be concluded that percutaneous vertebroplasty with calcium phosphate is effective in patients with traumatic vertebral fractures. Choosing the right patient, precise needle placement with fluoroscopic guide, timely injection of cement and experience play key roles in the success of this method.

Background & Objectives: Coronary artery disease is the most common cardiovascular disease and cause of a lot of deaths worldwide. In patients with this disease, symptom management is performed both pharmacologically and non-pharmacologically. Rhythmic breathing is one of the non-pharmacological proposed methods. The aim of this study was to investigate the effect of rhythmic breathing on the cardiorespiratory parameters in Acute Coronary Syndrome patients admitted at CCU. Methods: In this clinical trial, 80 patients with acute coronary syndrome were randomly divided into two interventional and control groups. The intervention group performed the rhythmic breathing for 20 minutes every 5 minutes once and it took 1 minute, and any intervention was not performed in the control group, but routine medical procedures were similar in both groups. Before and after the intervention, blood pressure, heart rate, respiration and oxygen saturation were recorded. The study instrument consisted of a demographic questionnaire and a data sheet for recording physiologic parameters, and the data were analyzed by using SPSS software. P values less than 0.05 was considered significant. Results:Based on the findings, there was no statistically significant difference between the groups in systolic blood pressure (P=0.65), diastolic blood pressure (P=0.53), respiratory rate (P=0.12), the rhythm of respiration (P=0.74), heart rate (P=0.61), the rhythm of the heartbeat (P=0.5) and arterial oxygen saturation (P= 0.67). Conclusion: Despite the lack of significant findings in this study, rhythmic breathing can be conducted in other cardiovascular diseases with a larger sample size, profiting from its potential benefits.
