Aims: Acute kidney injury (AKI) is characterized by a reversible increase in the blood concentration of creatinine and nitrogenous waste products and by the inability of the kidney to regulate fluid and electrolyte homeostasis appropriately.
Hyperuricemia is a feature of several pathologies and requires an appropriate and often early treatment, owing to the severe consequences that it may cause. A rapid and massive raise of uric acid, mainly damage the kidney.. Rasburicase, compared to allopurinol, results in more rapid reduction of uric acid and prevent its accumulation in patients with hematologic malignancy with hyperuricemia and AKI.
Methods: We evaluated the efficacy of rasburicase (0.15 mg/kg) administered as single dose in 15 patient with AKI in sheikh hospital, Mashhad University of medical Sciences. Beside conventional therapy, infusion of Rasburicase in 50cc normal saline in30 minute intravenously was done and all adverse reaction was treated.
Before injection of Rasburicase and 1st, 3nd and 7rd day after it urea, creatinine, uric acid and urine output were determined and compared.
Results: Within first 24 hour, the levels of serum uric acid in all patients decreased dramatically. there was a significant improvement in estimated GFR and urine output. Urea and creatinine level decreased from Day 0 to Day 7 but there was no difference between creatinine before treatment and 1st day.

Abstract
Introduction: Visfatin is a newly discovered adipokine which increases with obesity. It is not clear whether endurance training which induces changes in adipose tissue and blood lipids might decrease the plasma level of visfatin as well. The aim of this study was to investigate the effect of 9 weeks of aerobic training on serum visfatin level and insulin resistance index in obese women.
Materials and methods: Method of research was semiexperimental. Twenty-eight obese female volunteered and were randomly divided into experimental (14 subjects with means of weight 82 ± 10.2 kg, and BMI 34.2 ± 4.3 kg/m2) and control (14 subjects with means of weight 79.9 ± 9.5 kg, and BMI 34 ± 3.9 kg/m2) groups. Aerobic training protocol consisted of 4 sessions per week for 9 weeks. Each training session was a slow running trial at intensity of 65 to 75 percent of maximal heart rate for a period of 15 minutes. To follow the principle of overload, half-a-minute was added to each session after the second week, so that, at the last session the running time reached to 31 minutes. Before and after the training period, blood sampling was performed. Data were analyzed using independent t test and ANCOVA.
Results: Results showed significant reduction of serum visfatin level (p < 0.05), and no significant difference in insulin resistance index, serum HDL, LDL, TC and TG between the control and experimental groups (p > 0.05). In addition, aerobic training reduced significantly body mass index, body weight, waist to hip ratio, body fat percent, and increased significantly maximum oxygen uptake (p < 0.05).
Conclusion: It can be said that 9 weeks of aerobic training can cause significant reduction of serum visfatin and no significant change in insulin resistance index in obese women.

Background: Probiotics are beneficial and non-pathogenic microorganisms. Isolation of probiotic bacteria from traditional dairy products can not only lead to the isolation of probiotic bacteria with special characteristics, but it can offer a good approach for the mass production of traditional dairy products containing natural probiotic bacteria.
Materials and Methods: After collection of dairy products samples from different regions of Sabzevar, they were continuously cultured on the specific media of MRS and MRS Broth. Initial identification of isolates was performed by gram stain, motility test, nitrate reduction test, growth at 15 and 45 °C, growth at pH: 9/6 and fermentation capability of 11 different sugars. To identify desired strains more precisely, the 16S rDNA gene was amplified by PCR with specific primers and then sequenced and BLASTed. Acidic and bile salts conditions tolerance tests were performed for the final confirmation of desired strains.
Results: After continuous culture on specific agar media, 16 strains for further analysis were selected. In early identification of isolates by phenotypic methods, 14 strains were positive. To identify these strains more precisely, the 16S rDNA gene was amplified. Following molecular identification and sequencing of 16S rDNA gene, the BLAST sequence similarities were found with Lactobacillus planetarium. In addition, acidic and bile salts conditions tolerance tests showed that these bacteria had the best growth pattern at PH: 4 and they were able to grow in the presence of bile salts.
Conclusion: Biochemical results showed that the most common strains in the tested dairy products are Lactobacillus. These results also confirmed by the molecular tests. Acidic and bile salts conditions tolerance test, as a main characteristic of probiotic bacteria, showed that the strain was able to withstand these conditions.

Backgound: Neonatal respiratory distress is a main cause of preterm neonatal mortality. Surfactant is one of its standard treatments. The current study was conducted to compare clinical effects of different kinds of surfactant in the treatment of respiratory distress of preterm neonates admitted to NICU of Sabzevar.
Materials and Methods: This cross-sectional study was conducted on the preterm neonates admitted to NICU of Shahid Mobini Hospital of Sabzevar University of Medical Sciences, in 2009-2010. Sample size was 115 neonates at 95% confidence interval. Inclusion criteria were neonates with respiratory distress and 26-37 weeks gestional age who had been treated with surfactant. Exclusion criteria were neonates with 5-min Apgar score less than 7, neonates with major congenital anomalies, or neonates whose mothers received steroids before giving birth. The data were gathered by questionnaire to assess clinical effects of different kinds of surfactant in the treatment of preterm neonatal respiratory distress. The questionnaire was confirmed by content validity and inter-rater reliability (r=0.9). The data were analysed in SPSS software version 20 using descriptive statistics and non-parametric tests including ANOVA and multiple comparisons, kruskalwalis and chi-square.
Results: 41 neonates were allocated in a group with birth weight less than 1500 g and 74 neonates in a group equal or grater than 1500 g. According to the statistical tests, intubation duration in neonates less than 1500 g who received Newfactan was significantly more than the two other drugs (P=0.01). Duration of CPAP in Curosurf group was more than Survanta and Newfactan groups with a significant difference. Time of starting feeding was lesser in neonates who had recieved Survanta than Newfactan. In neonates less than 1500 g, none of the variables had a significant difference after surfactant therapy.
Conclusion: This study showed that Survanta has a better efficacy than Newfactan and Curosurf. But in regard to the importance of applying this drug, and the controversy of results obtained from studies, it is recommended to perform further studies about this issue.

Introduction: Now a days, musculoskeletal disorders are of a great concern in job health issues and their prevalence are relatively high among various occupations. On the other hand, agriculture is one of the most important production sections which have great roles in creating new jobs, and if these sections pay well attention, it can help in renewing economic growth, independency, and self-efficiency in our country. In the agricultural sections the workers do hard physical jobs, so these persons encounter musculoskeletal disorders more than the others.
Materials and Methods: This descriptive-analytical study was a cross-sectional one which performed among 400 farmers in Sabzevar. The data were gathered through Nordic Standard Questionnaire in which a group of trained persons completed it by interviewing. Gathered data were analyzed through statistical tests by the use of SPSS, v.16.
Results: The prevalence rate of musculoskeletal disorders in one or both knees, the waist and one or both feet and finally the ankle during one year was 52%, 46.5 and 27%, respectively. The result showed that during the last year, there was a significant relation between pain in waist and individuals’ weight (p = 0.033), pain in one or both knees and their age (p= 0.0001), pain in one or both knees and the height (0.036) and pain in shoulders and age (p=0.028).
Conclusion: The results showed that there is a significant relation between the musculoskeletal disorders in farmers and their demographic characteristics like weight, age and the height.

Introduction: Delirium as a syndrome which is recognized by consciousness disorder and changing in cognition. Delirium patients after by-pass are a common neurological complication, which is a component of the cognitive disorder. A high percentage of these kinds of patients suffer from after surgery. Evaluation of risk factors (blood transfusions and the use of more than one unit CPB) after surgery can be a valuable step in order to highlight the importance of prevention and early detection of delirium. This study aimed to recognize some risk factors related to delirium in patient who had a by- pass operation.
Methods: This study is a cross - sectional. The number of participants was 370 patients who had a by-pass operation were studied by the continuous sampling method. Researcher referred to the selected clinical centers in Tehran to identify related patients to our study and then informed consents were obtained from all patients. Using the Delirium Screening Scale, we analyzed psychological condition of patients until they were discharged from the critical care unit daily. The personal information questioner was completed on the first day of analyzing the psychological condition. Then the gathered data was analyzed by the SPSS 16 statistical package.
Results: Our findings showed that there was no meaningful statistical relationship between the incidences of delirium with risk factors despite its being common among participants.
Conclusions: According to these factors it is not possible to predict incidence of delirium in patients after a by- pass operation. In other words, there is an equal chance of delirium incidences among all patients’ regardless of having or not having these factors; therefore the analyzed factors of this study cannot be used to predict the delirium incidence.
