However, this treatment is not without risk of infections transmission including hepatitis B virus (HBV) and hepatitis C virus (HCV) and human immune-deficiency virus (HIV) in people who received the blood. Nevertheless, due to a high risk of blood born diseases through blood transfusion, screening for these viruses according to the World Health Organization (WHO) is mandatory. The main aim of this research was to assess the prevalence of HBV, HCV and HIV infections among healthy blood donors of Blood Donor Center of Ilam (BDCI). Materials and methods: In this study we used the information from first and repeated blood donors who referred to BDCI within February 2009 to January 2013. Demographic characteristics of donors including marital status, age, gender and blood donation pattern was extracted. Routine donor laboratory screening tests for HBV, HIV and HCV were performed. Results: HBV infection had the highest prevalence (0.14%) while HIV had the lowest ones (0.006%). The highest prevalence was among male blood donors. The prevalence of HBv, HIV and HCV infections were more common among men and first time donors (P < 0.01). The prevalence of  HIV and HCV infections were more common among married donors than singe ones (P < 0.01) HBV prevalence in singles was more (P < 0.05) compared to married blood donors. The highest and the lowest subjects with HBV, HCV and HIV infections were in range of 51 to 60 years and 18-35 years old, respectively. Conclusion: It is estimated that the prevalence of HBV, HCV and HIV infections are low in voluntary blood donors than general population which confirmed the effectiveness of education and examination of blood donors. This usually arising from the pre donation screening for risky behaviors, so deleting the high risk people. Since unsafe blood products are not used for blood transfusion, they are not considered as risk for blood safety system, but identification of these blood units is a problem for blood transfusion centers. 78 Cardiovascular Diseases The short-term survival following acute myocardial infarction: A prospective observational study Aryaie Mohammad j Bakhsha Fozieh k Jafari Seyyed Yaghub l Yousefi Zahra m Heidari Ali Reza n Esmaeili Zahra o Sobhani Sakineh p Aghili Shima j Health Management and Social Development Research Center, Golestan University of Medical Sciences, Gorgan, Iran k Laboratory Sciences Research Center, Golestan University of Medical Sciences, Gorgan, Iran l Laboratory Sciences Research Center, Golestan University of Medical Sciences, Gorgan, Iran m Laboratory Sciences Research Center, Golestan University of Medical Sciences, Gorgan, Iran n Health Management and Social Development Research Center, Golestan University of Medical Sciences, Gorgan, Iran o Research Committee, Golestan University of Medical Science, Gorgan, Iran p Research Committee, Golestan University of Medical Science, Gorgan, Iran Research Committee, Golestan University of Medical Science, Gorgan, Iran 1 3 2017 4 2 9 16 31 01 2016 15 07 2016 Introduction: To investigate 28 days survival rate following first acute myocardial infarction (AMI) associated with the presence of classical risk factors and treatment modalities in Gorgan, north of Iran. Materials and methods: Our cohort including all patients hospitalized due to AMI from 2010 to 2013. Data were collected on demographic, prophylactic drugs and classical coronary risk factors. Data were analyzed using Kaplan-Meier and log rank tests. Cox proportional hazard model was built to estimate relative risk by taking into account other variables. Results: Median age of subjects was 58 and 64 for men and women, respectively; moreover, the occurrence of diabetes was 52.5 and 24.5 for them. A poorer outcome was detected in survival rate for women in the final model. Excess death occurrence in Fars or non- Persian ethnicity, and those who were not prescribed statin was detected in the adjusted model. Conclusion: A better survival rate for those who were prescribed statin suggest that it could be beneficial in treatment modality and non-Persian ethnicities needed to be considered as a group of at risk for earlier screening programs. In spite of some other studies a poorer outcome following AMI for women was found even after taking into account age and comorbidity. 193 Medical Anatomy Functional recovery assessment of spinal cord contusion model in male rats without therapeutic interventions Rezaei Sara Bakhtiari Salar Asadollahi Khairollah Heidarizadi Somayeh Moayeri Ardeshir Azizi Monireh Department of Anatomy, Faculty of Medicine, Ilam University of Medical Sciences, Ilam, Iran Department of Biochemistry, Faculty of Medicine, Ilam University of Medical Sciences, Ilam, Iran Department of Epidemiology, Faculty of Health, Ilam University of Medical Sciences, Ilam, Iran Department of Anatomy, Faculty of Medicine, Ilam University of Medical Sciences, Ilam, Iran Department of Anatomy, Faculty of Medicine, Ilam University of Medical Sciences, Ilam, Iran Department of Anatomy, Faculty of Medicine, Ilam University of Medical Sciences, Ilam, Iran 1 3 2017 4 2 17 23 25 03 2016 08 08 2016 Introduction: Spinal cord injury (SCI) is one of the most serious clinical diseases, which not only affects the patient's physical and mental status, but its effects will be spread to family and community. After severe spinal cord injury, astrocytes of the central nervous system (CNS) become reactive astrocytes, and play the main role of glial scar formation. The scar is a major obstacle to regeneration of axons in the spinal cord. However, the studies have found that over time, a spontaneous partial motor recovery is observed in animals with injury without intervention. Thus, in this study, the recovery of animals with spinal cord injury was assessed after 12 weeks. Materials and methods: In this study, 12 adult male Wistar rats weighing approximately   265±15gr were used to assess spinal cord injury and randomly divided into 3 groups: normal control (n = 3), sham (n = 3), injury (n = 6). Healthy animals in the normal control group received no laminectomy or injury, and laminectomy with or without contusion model using weight drop in segment T10 of spinal cord were carried out in injury and sham groups, respectively. Locomotor function of animals in all groups were evaluated by BBB test at the first 48 hours per day and then weekly for 12 weeks. Results: Comparison of the results of motor evaluation from the second week to the twelfth week of the group with injury without treatment showed a relative functional recovery as the BBB score of animals from 1.4 in the second week after the injury reached to 6.5 in the twelfth week. Conclusion: The results indicate a spontaneous partial recovery in injured animals without intervention. 268 Medical Histology The effect of lansoprazole administration during pregnancy on the placenta Louei Monfared Ali Shamsi Morteza Department of Basic Sciences, Faculty of Veterinary Medicine, University of Ilam, Ilam, Iran Department of Parasitology, Faculty of Medicine, Ilam of University of Medical Sciences, Ilam, Iran 1 3 2017 4 2 24 28 01 05 2016 17 08 2016 Introduction: Lansoprazole is one of the proton pump inhibitor drugs widely used in the treatment of gastro-duodenal ulcers and disorders. However, there is not enough data about unexplored adverse effects of lansoprazole on the integrity of the placental barrier. Therefore, the present study was conducted to determine whether placental structure could be affected by lansoprazole administration. Materials and methods: A total of 24 pregnant Balb/C mice were randomly divided into one control and three experiment groups (n=6).The experimental animals were given 25, 50 and 100 mg/kg of lansoprazole intraperitoneally on days 6-16 of pregnancy. At the end point and on the day 17 of gestation all animals were sacrificed. Then, the placentas specimens were taken and processed for histological examinations. Histological sections were stained with hematoxylin-eosin and were examined under light microscopy. Results: The histological examinations showed remarkable cellular changes in the placenta after treatment with lansoprazole. The placentas from drug administrated mice exhibited conspicuous decrease in the spongy layers size when compared with controls. Also, both polymorph and mononuclear cell infiltration into placental parenchyma were seen in the animals treated with 100 mg/kg lansoprazole. In addition, dilation of the intervillous space, massive vasculature congestion, increased giant cell population and fibroblastic proliferation were seen in the placental tissues from experimental groups. Conclusion: The findings of the present study led us to investigate the effect of the lansoprazole administration on the mouse placenta. Taken together, this drug should not be prescribed during pregnancy. 260 Medical nanotechnology Investigation of UV/TiO2-N photocatalytic degradation of AR 40 using response surface methodology (RSM) Nademi Mohsen Keshavarz Moraveji Mostafa Mansouri Mohsen Department of Chemical Engineering, Islamic Azad University, Tehran North Branch, Tehran, Iran Department of Chemical Engineering, Amirkabir University of Technology (Tehran Polytechnic), Tehran, Iran Department of Chemical Engineering, Ilam University, Ilam, Iran 1 3 2017 4 2 29 40 01 06 2016 04 08 2016 Introduction: Advanced oxidation processes (AOPs) suggest a highly reactive, nonspecific oxidant namely hydroxyl radical (OH•), that oxidize a wide range of pollutants fast and non-selective in wastewater and water. Materials and methods: In this work, the nitrogen-doped titanium dioxide nanoparticles were primed by sol-gel method, characterized by X-ray diffraction and Scanning Electron Microscopy (SEM), for the degradation of Acid Red 40 (AR 40) solution in water. The effectiveness of the treatment method applied for the degradation of AR 40 based on AOPs was investigated. Results: The three various key parameters were optimized by using response surface modeling, namely: pH, TiO2-N concentration and the initial AR 40 concentrations. The optimized values were obtained at pH = 11, TiO2-N concentration = 0.09 g/L, and the initial AR 40 concentration = 19 mg/L. Conclusion: Under the optimum conditions, performance of photocatalytic degradation reaches 92.47% in 1 hr. Kinetic constant was evaluated using first-order equation to obtain the rate constant, K. 183 Medical Pathology The impact of fatigue on balancing in creating re-injuries in mountaineers with chronic ankle sprain Ebrahimi Himan Shahrokhi Mehdi Barmar Zahra Toktam Balouchi Ramin Department of Sport Pathology and Corrective Exercise, Faculty of Physical Education and Sport Sciences, University of Allameh Tabatabai, Tehran, Iran Department of Sport Pathology and Corrective Exercise, Faculty of Physical Education and Sport Sciences, University of Allameh Tabatabai, Tehran, Iran Department of Physical Education and Sports Science, Islamic Azad University of Mashhad, Mashhad, Iran Department of Physical Education and Sports Science, Islamic Azad University of Mashhad, Mashhad, Iran 1 3 2017 4 2 41 49 10 09 2015 16 12 2015 Introduction: Sensory-motor control and in general gaining balance will be impaired after an ankle injury and in fatigue situations. The aim of this research was to study the effect of exercise-based fatigue on static and dynamic balance in mountaineering athletes who were successful in returning to a suitable level of physical activity after an ankle sprain injury. Materials and methods: 25 active mountaineering athletes between 20 and 40 years were recruited on a voluntary basis. 12 persons with severe ankle sprain in the past were selected as experimental group and 13 healthy mountaineering athletes were selected as control group. Because balance test measuring was under the influence of evaluation time; fatigue test measurement running on the treadmill was performed in 2 sessions. Changes or fluctuations in the pressure Center or static balance were evaluated by Sharpened Romberg balance test and dynamic balance was evaluated by stability time after side jumping (the first session) and the maximum distance in the balance test Y (second session) were evaluated in the pre-test and post-test immediately after fatigue resulted by running on a treadmill. Data were analyzed using covariance test. Results: before fatigue condition, there were a few differences between the two groups in stability time while doing side jump test (P<0.014). After the fatigue and in balance test Y and stability time while doing side jump test; there were more differences (P<0.001). In this case, there was a similar increase on static swing in both groups. Fatigue was considerably reduced the static and dynamic postural control of the athletes who had a history of injury. Changes related to fatigue was significant in dynamic postural control in athletes with previous ankle sprain history. Conclusion: Even after the successful return to sport for athletes with previous damages, abnormalities in sensory-motor control and balance may lead to an increase the risk of ankle re-injury. 227 Immunology Mesenchymal stem cells as a reference cell for HLA-typing Mirzaee Khalilabadi Roohollah Yari Fatemeh Amirizadeh Naser Nikougoftar Mahin Oodi Arezoo Blood Transfusion Research Center, High Institute for Research and Education in Transfusion Medicine, Tehran, Iran Blood Transfusion Research Center, High Institute for Research and Education in Transfusion Medicine, Tehran, Iran Blood Transfusion Research Center, High Institute for Research and Education in Transfusion Medicine, Tehran, Iran Blood Transfusion Research Center, High Institute for Research and Education in Transfusion Medicine, Tehran, Iran Blood Transfusion Research Center, High Institute for Research and Education in Transfusion Medicine, Tehran, Iran 1 3 2017 4 2 50 57 02 01 2016 01 07 2016 Introduction: Recognition of human leukocyte antigens (HLA) is of importance for hematopoietic stem cell transplantation. Any HLA-mismatches between the donor and recipient can cause graft rejection or other complications. In HLA-typing experiments, usage of HLA-known reference cells accompany with HLA-unknown samples is obligatory. Some international centers represent these cells with high expenses. On the other hand, transferring of these cells is problematic and in some instances is not practical.  In this study, we introduced umbilical cord-derived mesenchymal stem cells (MSCs) as reference cells for HLA genotyping. These cells are national and can be prepared locally. Materials and methods: We isolated MSCs from three umbilical cord and after their growth and proliferation, these cells were characterized by flow cytometry technique using antibodies to CD29, CD34, CD44, CD45, CD73, CD90 and CD105. HLA-typing was then carried out by PCR-SSP kits for HLA-A, -B and -DRB allele’s identification. Results: Isolated MSCs were positive for MSCs markers; CD29, CD44, CD73, CD90, and CD105 and negative for hematopoietic stem cell markers; CD34 and CD45. HLA alleles were determined. One of the samples was homologous for HLA alleles and the others were heterologous. Conclusion: We can develop a reference panel for HLA-typing by obtaining MSCs from available sources like umbilical cord.
