Introduction: Many progresses has been made in the field of digital replantation which is based on progresses in microsurgery and surgeons skills in hand trauma. In this study, procedure and results of 97 digital replantatios are investigated. Materials and Methods: In this descriptive study 66 patients with 97 amputated fingers, who underwent replantation were studied. Only completely amputated fingers were studied and fingers with even the least connection to the proximal stump by a skin bridge were omitted from the study. Amputations were at the level or distal to the MCP joint. Results: Success rate of replantation was %57.7 which is 56 fingers from the total of 97 fingers. 58 patients were male and 8 female. Patients age was between 9-52 years. The total hospitalization period was 3-5 days for unsuccessful and 12-16 days for successful replantations. After the operation, Aspirin was used as the anticoagulant and heparin was used only after reexploration or in severe crushing injuries or in cases with vein graft use. Type of surgery and postoperative care was the same in all patients. Conclusion: Based on the results, it seems some reasons of lower success rate in our study in comparison to other countries are wrong transportation method of the amputed fingers and delay in patient transportation. Also surgeons, skill in plastic surgery seems to be effective.

Introduction: Free radical-mediated peroxidation of biological molecules, such as lipids, is implicated in the pathogenesis of multiple sclerosis and it's animal model experimental allergic encephalomyelitis(EAE). Low concentration of antioxidant vitamin E has been observed in serum of multiple sclerosis. However, it is not known whether vitamin E has protective effect in EAE. Vitamin E may inhibit EAE by effect on the level of uric acid and Nitric Oxide (NO) production. Materials and Methods: In this experimental study some male C57BL/6 mice were placed in two therapeutic groups (n=8 per group) with age and weight-matched as follow: 1)Vitamin E-treated EAE mice (10mg/kg/every two days of vitamin E given i.p from day-3 until day+19 after disease induction, 2) Non-treated EAE mice (EAE control) received vehicle alone with same schedule. In addition, 5 age and weight-matched male C57BL/6 mice served as normal (non-EAE) controls. Clinical score of disease, uric acid and NO levels of the groups were analysed. Results: Results showed that vitamin E-treated mice had significantly less clinical score of EAE (4±0.8) than non-treated EAE induced mice (5.3±0.44), (p<0.01). Also, there was difference at the onset day of the disease between vitamin E-treated and non-treated EAE-induced mice (day 13±1 and day 11±1, respectively), although was not significant. Concentration of uric acid in vitamin E treated mice were significantly lower than EAE control (p<0.001). There was no difference at the level of NO between the groups. Conclusion: Vitamin E had no effect on NO level, but decreased serum uric acid level. It suggests that vitamin E can reduce or delay the onset of EAE by increasing uric acid consumption.

Introduction: Renal cell carcinoma can be presented with extension of thrombosis to renal vein and inferior vena cava. Management of these patients consists of radical nephrectomy and thrombectomy. In this study we reviewed approach to these patients. Materials & Methods: This is a case series report. During 1379 to 1384, 148 patients diagnosed with renal cell carcinoma (RCC) limited to Gerota’s fascia (stage T3 or less) were admitted to Hasheminejad hospital. Fourteen patients had inferior vena cava (IVC) involvement. Radical nephrectomy as well as thrombectomy was performed in 8 patients. This investigation is done on these 8 patients. Results: Patients' average age was 51.4 years. Six patients were male (75%) and 2 female (25%). The most common symptoms were flank pain (75%), gross hematuria (62.5%) and structural symptoms (50%). All patients had tumors limited to Gerota’s fascia without any distant metastasis. Infrahepatic involvement of IVC was seen in 6 patients and in 2 patients thrombosis extended above the hepatic vein (infrahepatic). No perioperative mortality was seen. Postoperative complications were atelectasia in 2 patients and deep vein thrombosis in one which was treated with conservative management. Conclusion:By skillful surgical approach in patients with RCC and IVC involvement, thrombosis can be completely excised without increasing the rate of complications and longterm survival could be expected.

  Introduction: Patients` staying in recovery unit is associated with risks and complications and is expensive. Decreasing the duration of staying can both increase patients` safety and decrease hospital costs. Laryngeal mask airway (LMA) as a new instrument has been widely used for airway management and in this study, its effect on recovery time is investigated.

  Materials and methods: In a double blind randomized controlled clinical trial, 62 ASA Ι & Π patients were divided into two equal groups. In one group laryngeal mask and in the other, tracheal tube was used. The anesthetic drugs were similar in both groups. Patients with upper airway infections, as well as patients undergoing thoracic and upper abdominal surgeries were excluded. Those with more than one hour duration of anesthesia and more than 30 seconds need for intubations were also excluded. Duration of anesthesia was measured in minutes. Duration of recovery staying (in minutes) and complications were also recorded. Data was analyzed using Chi Square and Mann Whitney U tests.

  Results: There were no significant differences in age, sex and mean time of anesthesia between the two groups. But mean recovery time in LMA group with 10.65 minutes and tracheal tube group with 16.71 minutes was significantly different (P=0.007). Two patients (6.45%) in LMA and 11 patients (35.48%) in tracheal tube group developed complications during recovery period which was a statistically significant difference (P = 0.004).

  Conclusion: Laryngeal mask airway, decreased recovery time and the number and severity of respiratory complications. Complications such as cough, laryngospasm, bronchospasm, and arterial hypoxemia were significantly less in patients with laryngeal mask airway compared to patients with tracheal tube, so the use of LMA is recommended.

Introduction: The reason of infertility can have a direct influence on the plan and outcome of management. In this paper we intend to show the effect of tuberculosis (TB) history on female infertility among infertile couples attending to Rooyan infertility management center. Materials and methods: In this case-control study our cases were those who were diagnosed as infertile female and controls were those women whose husbands were infertile due to some male factor. We used logestic regression for analyzing the association of history of Tuberculosis and female infertility with attributable risk estimation. Results: 308 cases were compared to 314 controls. Considering the odds ratio and its 95% confidence interval, there was a significant difference between the history of TB and infertility (OR=4.7, 95% CI: 1.01-29.91). The attributable risk of TB for female infertility was 0.023±0.01 (which is significant at 5% level). Conclusion: These figures show that at least 2% of female infertility can be prevented by prevention and proper treatment of tuberculosis.

Introduction: Bone mineral density (BMD) measured by dual energy x-ray absorbtiometry (DEXA) is widely used in management of patients with osteoporosis. Factors which are specific to machine or operator, can influence the accuracy and precision of BMD estimations. In this study we investigated the effect of leg rotation and femoral neck on densitometry of femur. Materials and Methods: In a before and after, interventional study on 200 women between 30-70 years old, without metabolic bone diseases, densitometry was done first in standard position and then in 15ْ rotation of leg from standard position and then after changing femoral neck angle from 90ه to 80ْ in relation to central femoral neck axis . Density of femoral neck, ward triangle, greater trochanter, shaft of femur and total hip was measured and data was analyzed by means comparison test. Results: External rotation of leg by 15 ه from the customary position, increased the average BMD in femoral neck, wards area, trochanter and shaft (p<0.001, p<0.04, p<0.001, p<0.008 respectively).While no significant change was observed in average BMD of total hip. Change of femoral neck area angle from 90 ه to 80 ه in relation to central femoral axis decreased BMD in femoral neck (p<0.001), and significantly increased BMD in wards triangle, trochanter, shaft and total hip (p<0.001, p<0.001, p<0.001, p<0.04 respectively). Conclusion: Malrotation of hip can be an important confounding factor when interpreting serial BMD values. Regarding the less effect of malpositioning on BMD of total hip, this area may be prefered for assessment of densitometry result.

Introduction: One of the severe forms of affective disorders, defined in DSM-IV-TR, is bipolar disorder type1. This is a psychotic disease that coexists with structural and biochemical changes of CNS. It is probably under influence of environmental and/or genetic factors. Finger and hand prints are formed during the late first and second trimester of fetal development, and then remain unchanged. There are some suggestions that disturbance in dermatoglyphic patterns probably are in relation with appearance of bipolar disorder. It seems that this disturbance is appeared at the first and second trimester of fetal development, which is a critical period for CNS growth. This study is done to investigate the dermatoglyphic patterns in bipolar disorder. Materials and Methods: This is a case-control study in which we have studied the dermatoglyphic changes in 30 bipolar disorder patients and compared to those of 72 healthy controls. The χ2 test was used for quantitative and T-test for qualitative data analysis. Results: Results showed that TABRC in patients was decreased in comparison to healthy people but this decrease was not significant. Regarding the type of patients, fingerprints, Loop and Whorls forms were heterogenous and were significantly different in comparison to control group (p=0.001, p=0.003). Conclusion: It seems that dermatoglyphic patterns can be an interesting and probably suitable procedure in determining the prognosis of bipolar disorder type 1 and other psychiatric disorders.

Introduction: Kalleh-Pacheh is an Iranian food used in many part of Iran and many other countries such as Afghanistan, Pakistan and India. We found no information regarding the effect of this food on acute myocardial infarction. The aim of this study was to assess the effect of this food, together with diabetes and smoking on myocardial infarction in Arak district. Materials and Methods: This was a case-cohort study which was performed in Arak district. In this study the data of Arak sub-cohort was taken from Isfahan healthy heart project which was performed in 2001. Cases were myocardial infracted hospitalized patients who were resident in Arak at the time of study. We showed the effect of different exposure, on myocardial infarction by estimating relative risk and population attributable fraction and 95% confidence interval. Results: In this study 150 cases were compared with 6339 sub-cohorts. The population attributable fraction for Kalleh-Pacheh was 19% (95% CI, 6 to 30%). This measure for diabetes and smoking was 31% (95% CI, 23 to 39%) and 41% (95% CI, 31 to 49%) respectively. Conclusion: According to the results of our study smoking, diabetes and using Kalleh-Pacheh has significant effect on myocardial infarction

Introduction:Final examinations are important stressors in schools and universities that result in different psychoneuroimmunological outcomes but the study of these effects on children has not been paid enough attention to. The aim of this study is to investigate the effect of final examinations on salivary immunoglubulin A in children. Materials and Methods: In this clinical trial a total of 100 children (50 boys, 50 girls) in 5th grade, aged less than 12 years from two primary schools of 5th educational district in Tehran were choosen randomly. The subjects completed Test Anxiety Scales of Sarason & Abolghasemi. After making sure of their physical and mental health by reviewing their medical history, clinical examinations and after controlling sleep, food, drug and sport variables, based on time series design, salivary IgA samples were taken five times as followed: one week before and then three times through mathematics, history and science exams and at last one week after passing the exams at, 9 to 10 am. IgA samples were analyzed by nephlometry method. Data was analyzed using ANOVA. Results: Findings indicated that IgA level was decreased significantly during examinations comparing to IgA levels before and after examinations (p=0.01). The relations of sex and anxiety scores were not statistically significant. It means that decreased IgA levels are the same in all children. Conclusion: Final examinations as a stress resource, diminishes IgA and this change is not related to sex and test anxiety score.

Introduction: Chest wall in children is more compliant, slow twitch muscle fibers are less than adults and the alveolus are smaller in size and lesser in number. Airways are more expandable and smaller in diameter. In the other hand the inhalational anesthetics can cause respiratory depression and rapid shallow ventilation. These changes can cause microatelectasia, low respiratory system compliance and increase in work of breathing. Controlled ventilation probably will prevent these events. This study is going to compare behaviors of respiratory system under inhalational anesthesia. Materials and Methods: In a clinical trial, 60 pediatric patients between 6 months to 6 years of age, ASA I & II, who were candidates of elective surgery on extremities and lower abdomen, entered to study. Patients were randomly allocated in two groups of spontaneous and controlled ventilation. In the first group inhalational and in the second group intravenous inductions was performed. Both groups were given halothane (0.8-1%) in a 50% mixture of N2O and O2 for maintenance of anesthesia. HR, RR, BP, SPO2 and T before induction and all of these plus EVT and peak and plateau APs, 5 minutes after induction and every 15 minutes thereafter were measured and dynamic and static compliance were calculated by using measured data. Data was analyzed by ANOVA, T student and Chi square tests. Results: Patients in spontaneous ventilation group had significantly more RR and EtCO2 and less awakening time (p<0.05).Total mean of HR, SBP, DBP, SPO2, T, PIP, PltIP, dynamic and static compliance after induction of anesthesia had no statistical differences between the two groups. Conclusion: There are no constant significant differences between the two groups in respiratory system compliance, airway pressures and T and this study can not prove the development of significant changes in respiratory system indices between the two groups. Thus microatelectasis (if developed) is not clinically important during less than one hour surgeries.

Introduction: Secondary hyperparathyroidism (SHPT) is one of the serious complications in patients with chronic kidney disease (CKD). This study aimed to identify biochemical alterations of renal bone disease in hemodialysis patients of Qazvin province. Materials and Methods: In a descriptive study, fasting blood samples of arterio-venul shunt, before starting hemodialysis, were taken from all CKD patients and Ca++, P-- and ALP were measured by colorimetric methods and PTH by IRMA method. Descriptive statistics was used to present data. Results: In 4% of cases there were no abnormalities of mentioned parameters but in 96% of patients one or more parameters were abnormal. The most prevalent abnormality was related to P-- (increased) and the least one to ALP (increased). 51% of patients had raised PTH level (hyperparathyroidism) and higher abnormalities of other biochemical parameters. No differences were seen in the mean of age, duration and number of hemodialysis and also sex ratio of hyperparathyroid patients and all studied patients. Conclusion: The Biochemical and hormonal results revealed a predominance of mild to moderate secondary hyperparathyroidism and renal bone disease in CKD patients, so there is a need to control the disease with specific treatments.

Introduction: World health organization has proclaimed the prevalence of smoking among 15 years old European region students, more than 24 percent. The cigarette smoking indicator in our country among over 15 years old individuals is 11.9 percent and in the province under survey is 15.6 percent. This research has been performed in order to study the effect of health education program based on health belief model (H.B.M) on preventive actions of smoking in middle school students. Materials and Methods: This is a quasi-experimental study, done on 248 students of grade one in middle schools of Boukan city (119 boys and 129 girls) that were randomly divided into experimental and control groups. Data collection tool was a questionnaire including 77 questions based on health belief model (perceived susceptibility, perceived severity, perceived benefits and perceived barriers to smoking, and cues to action) and preventive actions of smoking. After data collection in the first stage, action was taken with regard to educational intervention and then in the second stage (after the intervention), data was collected again. Data was analyzed using T test. Results: Results showed that the mean score of all parts of health belief model in experimental group(except for perceived barriers) after educational intervention compared to before intervention was increased significantly and also the mean score of all parts of HBM after intervention was significantly increased in experimental group compared to control group. Conclusion: The results of this survey show that by increasing the score of health belief model parts including, perceived susceptibility, perceived severity and perceived benefits, adopting preventive actions of smoking also increases. Therefore, the results of this survey confirm the efficiency of health belief model in adopting preventive actions of smoking.

Introduction: The acute response to renal ischemia-reperfusion injury involves attenuation of glomerular filtration rate, as well as reduced tubular function. The possible mediators involved in ischemia-reperfusion injury include vasoconstrictor agents including angiotensin II (Ang II). Inhibition of the angiotensin II receptor type 1 (AT1) diminishes the deleterious effects of ischemia-reperfusion on glomerular function. This study is done to investigate the effect of angiotensin II receptor type 1 antagonist on renal hemodynamic and tubular responses to ischemia-reperfusion injury in rat. Materials and Methods: In this experimental study, acute renal failure was induced by 30 minutes clamping of both renal arteries in male Sprague-Dawley rats. Renal hemodynamic and excretory function was followed for 120 minutes reperfusion, while saline or the selective AT1 receptor antagonist (Losartan) was infused. In plasma and urine samples, Cr level was measured. Also plasma and urine content of Sodium was measured. Data was analyzed using ANOVA and Duncan tests. Results: Renal ischemia for 30 minutes decreased glomerular filtration rate during reperfusion and increased urine flow and Sodium excretion up to three fold. Losartan (10 mg/kg i.v.) did not change glomerular filtration rate prior to ischemia but improved it during reperfusion and there were progressive increases in urine flow. Losartan caused a lowering of ischemia-induced rise in Sodium excretion. Conclusion: The ischemic challenge may cause release of angiotensin II, which acts on AT1 receptors to decrease perfusion.

 Introduction: Experimental autoimmune encephalomyelitis (EAE) is an animal model of multiple sclerosis distinguished by infiltration of leukocytes into the central nervous system. Changes in composition and levels of unsaturated fatty acids, affect the integrity of blood-brain barrier. In this study, we evaluated the effect of Sesame oil on the leukocyte infiltration into the brain of MOG35-55 induced EAE male C57BL/6 mice. Materials and Methods: In this experimental study, male C57BL/6 mice were placed in two therapeutic groups (n=10 per group) with age and weight-matched as follow: 1.Sesame oil-treated EAE mice received 4ml/kg/day of Sesame oil given i.p. from day -3 until day +19 after disease induction, 2.Non-treated EAE mice (EAE control) received Phosphate buffer alone with same schedule. EAE was induced by immunization of mice with MOG35-55 peptide and complete Freund's adjuvant. Leukocytes infiltration into the brain was investigated 20 days after immunization. Data was analyzed using Mann-Whitney U test. Results: The results show that Sesame oil-treated mice had significantly less clinical score of EAE (2.6±0.4) than non-treated EAE induced mice (4.2±0.6), (p<0.001). Also, there was a significant difference at number of the infiltrating cells in brain between Sesame oiltreated (80±20) and non treated EAE-induced mice (150±30), (p<0.01). Conclusion: These results indicate that Sesame oil reduces infiltration of leukocytes into the brain of EAE mice, therefore lessening the histological changes and clinical signs and thus ameliorating the disease.

Introduction: Nowadays, the attention of researchers has been focused on natural medicine in order to avoid the detrimental side effects of chemical drugs. In this study we assessed the effect of root extract of Tagetes minuta against HSV-1 and HSV-2. Materials and Methods: This research is an experimental study. Root extract of Tagetes minuta was obtained with 70% ethanol by maceration. Vero cells were grown in DMEM containing 5% fetal bovine serum. Serial dilutions of extracted suspension (1/10, 1/20, 1/40, 1/80, 1/160) were incubated by the exact titer of viruses and monitored for antiviral activity of extract. Data was analyzed using Doncan test. Results: Root extract obtained from Tagetes minuta significantly has antiviral activity against HSV-1 and HSV-2. This extract has more effect on HSV-2 than HSV-1. This study indicates that antiviral activity of the extract varies between different concentrations and the optimum antiviral activity on both viruses was obtained using 1/10 concentration. Conclusion:The results of this investigation showed that root extract of Tagetes minuta have good antiviral potenoial against HSV-1 and HSV-2, a good source of drug for treatment of diseases due to HSV-1 and HSV-2.

Introduction: Cataract is one of the most important and a major disease in human. The prevalence of cataract in age 65-74 get to 50%, and over 75 it arrives to 70%. Absolute cure for cataract is surgery that can be done by different techniques such as intracapsular, extracapsular, and phacoemulsification. Cataract surgery has different side effects such as hemorrhage, Glaucoma, posterior capsular opacification and astigmatism. This study decides to compare astigmatism after two techniques of cataract surgery phaco and extracapsular. Materials and Methods: This study is a double blind randomized clinical trial, which has been experienced on 112 patients. Patients were divided in two groups (A and B). In group A surgery was done by phaco technique which has a small incision of 3.2 mm and does not need suture. But in group B, (extracapsular group) the incision is bigger about 10 mm and needs suture. Then keratometry was done for each patient before surgery, one week and 2 months after surgery for determining astigmatism. Data was analyzed by independent and paired sample T tests. p< 0.05 was considered meaningful. Results: From 112 patients that had been studied, 56 patients underwent phaco technique and 56 patients underwent extracapsular technique. Mean of astigmatism before surgery in group phaco was 0.79±0.71 D and in extracapsular was 0.90.55 D (p>0.05). Mean of astigmatism 1 week after surgery in phaco group was 1.110.72 D and in extracapsular group was 3.991.46 D (p<0.05) and mean of astigmatism two months after surgery in phaco group was 1.00.71 D and in extracapsular group was 3.281.29 D (p<0.05). Conclusion: Induced astigmatism in phaco group was 0.21 D and in extracapsular was 2.38 D, that has meningful difference. Other criteria such as age, lens number, sex and left or right eye do not have any effect on induced astigmatism.

Introduction: Menopause is a natural period of life. It means the permanent cessation of menstruation and the end of reproductive period which occurs between 45-52 years old. It also serves as an indicator of population health as the occurrence of menopause indicates the increased risk for the onset of several chronic diseases. In this study, the mean age of natural menopause among women in Arak (Central Iran) was investigated, considering their reproductive and socio-economic-demographic factors and their health behaviors. Materials and Methods: This study was an observational cross-sectional study on a population base, carried out in 2007 year. Interviews and questionnaires were used for gathering data from 458 women resident in Arak city, who had undergone a natural menopause. Sampling was multistaged using postal zones and selecting samples in each zone. Data was analyzed using variance analysis, multiple regression, T and correlation coefficient tests. Results: Findings showed that the mean age of menopause in our sample was 48.2±2.34 years (95% CI: 47.98- 48.41) and its median was 49 years. The mean age of menopause in women who were never married was less than married women (P= 0.015). Low income level (P= 0.003), having physical activity (P= 0.004), number of pregnancies (P<0.001), age of last pregnancy (P=0.026) and place of birth (P=0.003) were meaningfull factors in age of menopause. Conclusion: This phenomenon must be documented in Iran because of its strong link with mortality and morbidity of the growing number of women who are reaching advanced ages whose one forth of life is after menopause. Therefore health education as the best way for changing their lifestyle is suggested.

Introduction: Depression is one of the most common affective disorders, and in addition to different neurotransmitters and life events, various internal stressors such as blood glucose, cholesterol, triglyceride and other factors are responsible for it. Considering hyperglycemia as a possible risk factor of this disorder and inconsistency in results of previous studies, we decided to assess the relationship between different levels of HbA1C and major depression. Materials and Methods: This is a cross-sectional analythical study that is carried out on 134 samples. They were chosen randomly among patients with type2 diabetes reffering to Vali-e-Asr hospital. The patients were divided into 2 groups on the basis of their HbA1C test results patients with HbA1C less than 7% (group A), consisting 55 persons and patients with HbA1C more than 7% and equal to it (group B), including 79 persons. Participants were assessed by Hamilton scale of depression. The relation between HbA1C levels and major depression in these 2 groups was assessed using Chi square and Mann Whitney U tests. Results: We found that 40% of depressed patients had HbA1C level lower than 7% and 60% of them had HbA1C level higher than 7%. No significant correlation was found between HbA1C and major depression. But the duration of disease, using Insulin and being hypertensive simultaneously was correlated to major depression in this study. Conclusion: This study indicates that uncontrolled diabetes and high level of blood glucose is cosidered of less importance as an undelying mechanism of depression in patients with type 2 diabetes.

Introduction: Diabetes is the most important metabolic disease in human. The prevalence of both types of diabetes is rapidly increasing ocross the world. Diabetes causes many complications including End Stage Renal Disease (ESRD). Diabetes is responsible for 30% of ESRD. The prevalence of diabetic nephropathy in Iran is also high. Many of these patients are becoming dialysis dependent. Many studies have shown the changes of trace metals’ levels in diabetic patients including Copper, Zinc, Manganese and Chromium. This study evaluates the correlation between urinary Copper and diabetic nephropathy Materials and Methods: This is a case-control study. Samples were selected among type 2 diabetic patients attending to diabetes clinic in Vali-e-Asr hospital in Arak. Diabetic patients were divided in two groups based on microalbuminuria, 42 patients in case and 40 patients in control group. Then the patients were classified based on duration of diabetes into 4 groups and based on the HbA1c into two groups. Then urinary Copper was determined with atomic absorption spectophotometry and compared. Independent t-test was used to analyze data. Results: Patients were 28.1% male and 69.9% female in case group and 37.5% male and 62.5% female in control group. The mean Copper level was 36.14µg /L (14.54-57.74) in case group and 14.77% µg /L (10.17-19.37) in control group. There was a statistically significant difference between the two groups (p=0.003). Conclusion: The results show a positive relation between urinary Copper and diabetic nephropathy and confirmed the results of other studies that reported the elevation of Copper in microalbuminuria. This study also showed that age, gender, duration of diabetes and HbA1c level have no effect on urinary Copper.
