T regulatory cells are effective cells in reaction with dendritic cells and have an important role in treating of diseases. Objective: To evaluated the effect of TGF-β(Trancforming Growth Factor β) Cytokine in dendritic cell generation and capacity of these cells in regulatory T cells development in culture media. Materials and Methods: In this experimental study, blood samples were obtained from 5 volunteers, then peripheral blood mononuclear cells were isolated by using Phicole Hypaque, dendritic cells of peripheral blood monocyte were produced by GM-CSF, IL-4 and TGF-β in comparison with control group. Mixed leukocyte reaction was accesed in allogenic T cell and dendritic cell. The number of CD4+CD25+ T cells, CD14+ and their surface markers were evaluated by Flowcytometry. Results: In this study, dendritic cells produced in presence and without presence of TGF-β cytokine. The proliferation level of T cells decreased in mixed leukocyte reaction with dendritic cell-treated TGF-β in comparison with control group. In addition, the number of T CD25+ cells increased 27 percent in culture media including dendritic cell-treated TGF-β in comparison with control group(p<0.05). Conclusion: The TGF-Beta molecule caused effect on the dendritic cells and producted cells with inhibiting of immune responses in mixed leukocyte reaction. So it concluded that, these cells can be have an important role in preventing of unwanted immune reaction invitro.
153 Special Evaluating the Microleakage of Class V Cavity Preparations Restored with Resin Composite and Resin Modified Glass Ionomer Falahzadeh F e Yousefi A f Parsafar A g e Ghazvin University of Medical Sciences f Ghazvin University of Medical Sciences g Ghazvin University of Medical Sciences 1 4 2011 20 77 8 14 10 11 2013 10 11 2013 Abstract Introduction: Marginal seal in class V Cavities and determining the best restorative material to decrease microleakage of them is very important in operative dentistry. Objective: To evaluate the microleakage of class V cavity preparations restored with three different types of resin composite and resin modified glass Ionomer. Materials and Methods: Two class V cavities were prepared in buccal surface of 32 recently extracted premolar teeth. The occlusal margin of each restoration was on enamel and the gingival margin on dentin. Teeth were randomly assigned to four groups of 8 teeth and restored as follows: Group I: microhybrid resin composite (Z250) Group II: nano composite (supreme) Group III: Flowable composite (3M) Group IV: resin modified glass Ionomer (vitremer). In all groups, the manufacture instructions were strictly followed. All teeth were immersed in 50% Silver Nitrate during 4 hours and developing solution for 8 hours after thermocycling. The teeth were longitudinally sectioned and observed under a stereomicroscope. The degree of dye penetration was recorded and analyzed with the kruskal-wallis and mann-whitney test. Results: There was no evidence of microleakage on the enamel margins in any groups. When the margins were in dentin, vitremer and flowable composite had the less and the most level of microleakage in dentinal margine respectively (p<0.05). There was no significant differents in other groups of dentinal margin. Conclusion: Vitremer has an efficterness role and flawable composite has a weakness role in reducting microleakage of dentinal margin. 154 Special Emotion Regulation Strategies in Stbstance Abusers with High and Low Reactivity Abolghasemi A h Alah Gholilo K i Narimani M j Zahed A k h University of Mohaghegh Ardabili i University of Mohaghegh Ardabili j University of Mohaghegh Ardabili k University of Mohaghegh Ardabili 1 4 2011 20 77 15 22 10 11 2013 10 11 2013 Abstract Introduction: Reactivity and negative emotion regulation strategies increased the proboblity substance abuse.

Conclusion: This Study indicated that high reactivity and use of negative Emotion regulation strategies are the risk factors for substance abuse. 155 Special Survey the Relationship between Perfectionism and Job Burnout in Nurses Hajloo N l Sobhi Gharamaleki N m Rahbar Taramsari M n Haghighatgoo M l University of Mohaghegh Ardabili m University of Mohaghegh Ardabili n Guilan University of Medical Sciences 1 4 2011 20 77 23 30 10 11 2013 10 11 2013 Abstract Introduction: Perfectionism is considered as a characteristic personality for striving performance without deficiency of excessively high standards by tendencies for overly critical evaluations of one’s behaviour in addition job burnout is a variable that could be increased by unhealthy perfectionism and outcomes. Although perfectionism considered appropriate but it may lead to increase some problems like burnout in some vocations like nursing. Objectives: Investigating the relation between perfectionism and job burnout in 344 nurses in Rasht in 2008. Materials and Methods: In this descriptive- correlation study, 344 nurses were selected by cluster random sampling of Razi, Dr Heshmat, Velayat, Poorsina and Amir- al- momenin Hospitals in Rasht. Frost multi perfectionism inventory was used for studying perfectionism and Maslach and Jakson’s job burnout inventory was used for studying job burnout. Correlation coefficient and regression and Manova were used for data analysis. Our hypothesis imparted reverse correlation between positive relation and negative dimensions of perfectionism. Results: The results showed that there was a negative relation between job burnout, organization, parental expectance and personal standards (t=-0.227,-0.131,-0.132 respectively, P<0.05). Regression analysis showed that just organization dimension can predicted job burnout in our sample (Beta=-0/197, t=-3/555).In addition age was significant in two younger groups as a prespective variable in relation with profectionism criterion variable. Conclusion: This study showed that job burnout will be decreased by improving positive dimensions of perfectionism such as organization and personal standards. Also perfectionism in younger nurses is more than older ones, so it is better to improve positive dimensions of perfectionism to promotion the quality of their services. 156 Special Anxiety-Depressive Disorders among Irritable Bowel Syndrome (IBS) Patients Modabernia M.J p Imani A Mirsafaye Moghaddam S.A.R Mansour Ghanaei F Sedigh Rahim Abadi M Yosefi Mashhour M Jokar ‌‌F Atrkar Roshan Z p Guilan University of Medical Sciences Guilan University of Medical Sciences Guilan University of Medical Sciences Guilan University of Medical Sciences Guilan University of Medical Sciences Guilan University of Medical Sciences Guilan University of Medical Sciences Guilan University of Medical Sciences 1 4 2011 20 77 31 39 10 11 2013 10 11 2013 Abstract Introduction: Psychiatric disorders are common in Irritable Bowel Syndrome (IBS) patients. Prevalence of psychiatric disorders is varies in IBS patients in different societies. Objevtive: To determine the prevalence of psychiatric disorders (anxiety-depression) in IBS patients in Rasht. Materials and Methods: In this cross-sectional study, 256 IBS patients were selected (using criteria of Rome III) and evaluated for psychiatric disorders. In the first phase, subjects were screened by GHQ28. In the second phase, those patients who had scores equal or more than 23 were assessed through semi-structured psychiatric interview. Socio-demographic variables including age, gender, marital status, educational level and occupation, were recorded as well. P-values less than 0.05 were considered statistically significant. Results: Among 256 subjects 30 patients (11.7%) had no significant psychiatric symptoms and 226 subjects (83 male, 143 female) suffered from some degrees of psychiatric problems. After performing semi-structured psychiatric interview 190 subjects (74.2%) had anxiety-depressive problems [89 patients were suffered from pure anxiety disorders, 41 patients suffered from depressive disorders and 60 patients had co-morbid anxiety-depressive disorders]. In anxiety disorders generalized anxiety disorder (53.7%) and in depressive disorders dysthymia (53.5%) had the most frequencies, 53.7% and 53.5% respectively. In comparisone of anxiety-depressive subjects (190 persons) and normal subjects (66 persons), there was a significant statistical differences between the gender (P=0.019), occupation (P=0.002) and intensity of IBS (P<0.001). Conclusion: Although, further studies are needed to determine the relations of demographic variables and types of IBS with psychiatric disorders, it seems to more attention to the psychiatric disorders of some specific patients suffering from IBS is helpful to their treatment 157 Special Comparison the Personality Characteristics between Male and Female Patients with Irritable Bowel Syndrome (IBS) Younesi F Kafi M Aminian K Ghanbari A Azad Islamic University Guilan University Guilan University of Medical Sciences Guilan University of Medical Sciences 1 4 2011 20 77 40 48 10 11 2013 10 11 2013 Abstract Introduction: Irritable Bowel Syndrome (IBS) is the most common gastrointestinal disorder in clinical medicine, since it is not founded biological basis for it, role of psychological causes is investigated in creation of it. Objective: To compare the personality characteristics between three groups of patients with Diarrhea dominant, Constipation dominant and dominant of Altering type and investigating the gender, family background of IBS and length of illness . Material and Methods: Eighty five patients were selected through temporal classical random method and included of 21 patients with Diarrhea dominant, 30 patients with Constipation dominant and 34 0patient with Altering type). Patients were diagnosed by a gastroenterologist and using the ROME  criteria after clinical evaluation and endoscopy. Personality inventory (NEOPI-R) made by Mc Crue and Kosta containing big five personality factors was used for investigating the sampel‘s personality characteristics. Demographic characteristics and other groups were recognized by question made at the first of main questionnaire. The groups eperated of each other. Result: Analysis of data indicated that there were no significantly differences between the personality characterisrics in three groups of patients. Extraversion was significantly higher in patients with family background of IBS and patients who had IBS more than six mounth and had reported stress gained higher score at neuroticism in comparison with patients who had IBS less than 6 month and had not report stress. Conclusion: Psychological factors participated at quality of illness experience. Neuroticism may be correlated with quality of illness experience (with stress and high length of illness). Thus personality characteristics should be considred as an important factor in improvement of IBS patients by psychiatrics and specialists. 158 Special Postoperative Mortality and Morbidity of Carotid Endarterectomy in Patients with Carotid Stenosis Hemati H Moghadam nia M.R Shakiba M Roudbari A Yousefzadeh Chabok SH Rimaz S Guilan University of Medical Sciences Guilan University of Medical Sciences Guilan University of Medical Sciences Guilan University of Medical Sciences Guilan University of Medical Sciences Guilan University of Medical Sciences 1 4 2011 20 77 49 54 10 11 2013 10 11 2013 Abstract Introduction: Carotid stenosis is the most common cause of crebrovascular accidents. If we select the patients appropriately, carotid endarterectomy would be acceptable regarding to mortality and morbidity for vascular complications. Since, carotid endarterectomy related complication is dependent on experience, equipment and facilities of surgical team, each surgical ward should be evaluated for complication separetely. Objective: Evaluating the postoperative mortality and morbidity and complication of carotid endarterectomy in patients with carotid stenosis in surgical wards of Razi Hospital in Rasht during September 2006 until end of February 2010. Materials and Methods: In this descriptive study, 51 patients undergoing carotid endarterectomy in surgical wards of Razi Hospital were recruited. Postoprative complications, mortality and morbidity of carotid endarterectomy were recorded during hospitalization and one month follow up period after discharge. Results: The mean age of patients was 66.69±10.33. 35 subjects of patients were male and 16 subjects of patients were female. Mortality was reported in one case (%1.96), complication in asymptomatic patient was (%1.96), in symptomatic patient with Transient Ischemic Attack was (1.96%) and in Cerebro Vascular Accident patients was (0%). Conclusian: Results of this study showed that the rate of mortality and morbidity is acceptable after endarterectomy surgery in Razi hospital in comparison with NASCET. So in order to elevation of quality of surgery in this center, results of surgery should be recorded and analysed every year. 159 Special Comparison the Method of wrist Supination with Elbow Flexion as Classical Method with Hyperpronation Method in Reduction of Radial Head Subluxation in Less than 7 Years Old Children Asadi K Mardani M Guilan University of Medical Sciences Guilan University of Medical Sciences 1 4 2011 20 77 55 60 10 11 2013 10 11 2013 Abstract Introduction: The radial head subluxation is a common cause in less than 7 years old children who refered to emergency center after pulling of their wrist by parents. Objective: Compare the method of wrist supination with elbow flexion as classical method with hyperpronation method in reduction of radial head subluxation (pulled elbow) in children less than 7 years old referig to poorsina hospital during 2004-2009. Materials and Methods: In this randomized clinical trial, children who had referred to Poursina orthopedic emergency center with clinical diagnosis of radial head subluxation were studied consequent. Patients were randomly treated as consequent male and female with one of two methods. The patients were checked in order to diagnosis extremity function's return every 5 minutes. If extremity function had not returned, the primary method was repeated after 15 minutes. Unsuccessful treatment led to treatment with another method 30 minutes after first try. That method repeated if replacing method was not successful after 15 minutes. If both methods were unsuccessful, elbow radiography to roll-out other injury was performed. After collecting data, analysis was performed using chi- square test and T- test with SPSS software version 16. Results: Among 110 patients were included in this study with average age (4.05±1.51 years) 58 patients (3.91±1.41 years) with first method (SF) and 52 patients (4.21±1.62 years) with second method were treated. (P=0.31) %62.7 of patients were male and the remaining were female (%37.3). In 47 patients (%90.4) of 52 patients who were treated by (HP) method. This was 46 patients (%79.3) from 58(P=0.11). Five patients of (HP) group needed second attempt where as this number were 12 about (F) group. Treatment with (HP) method was successful in 100 percent patients, but successful rate was %87.9 for (SP) method. There was significant superiority of (HP) success in comparison to (SF) (P+0/006). Conclusion: In reduction of radial head subluxation(HP) method was more successful upination method in reduction of radial head, it is more successful than supination, when supination was not successful than(SF) method. 160 Special Epidemiological Features of Needle Stick Injuries among Nursing Staff Bijani B Sotudehmanesh S Mohammadi N Bualisina Hospital Bualisina Hospital Tehran University of Medical Sciences 1 4 2011 20 77 61 68 10 11 2013 10 11 2013 Abstract Introduction: Injury with contaminated sharp devices like used needles is the great potential risk factor in nursing staff.

This artery which was described in the all anatomical textbooks may arised from the arch of aorta, brachiocephalic trunk or other arteries in the upper mediastina. It is considered as a compensatory artery when the other thyroidal vessels showed deficiencies. This artery showed greatly variation in size and gave some anastomotic branches to the thymic artery. The thymic artery arised from the anterior mediastinal branch of the internal thoracic artery but, may also arised from the brachiocephalic trunk, arch of aorta, common carotid or the main trunk of the internal thoracic artery. Its origin from the thyroidea ima is rare. Case History: This rare case was seen in a 65 years old male cadaver, the common trunk of the thyroida ima and the thymic arteries originated from the brachiocephalic artery. After a short course it divided into two branches: an ascending (thyroida ima) and descending (thymic) branches. The thyroidea ima artery turned to left and upward to the lower border of the isthmus of thyroid gland. At this point it sent a branch to the lower part of the left lobe of the thyroid which penetrated it deeply and ended in the left inferior parathyroid gland. The main branch continued its course upward to the upper border of the thyroidal isthmus and divided into right and left branches. Each of these branches, after sending a great anastomotic branch to the superior thyroidal artery of their own side, terminated as several small branches in the upper part of the right and left lobes of the thyroid gland. The thymic artery continued its course downward for about three centimeters and ended as two branches in the right and left lobes of thymus. The thyroid gland of this cadaver was larger than the normal ones and the thymus was also clearly noticeable with right and left bobs. Conclusion: According to the embryonic origin and the developmental processes of the inferior parathyroid glands and the Thymus from the neighboring pharyngeal pouches, their blood supply from a common trunk will be acceptable especially when these two glands show some degree of enlargement as shown in this case. In the cases of thyroidectomies, when a surgeon is going to resect an enlarged thyroid gland, the presence of thyroidea ima artery and its branches to the lower part of lobes of thyroid gland would be a useful guidance to identify the inferior parathyroid glands an save them for the prevention of the next hypocalcemia.
