Abstract
Introduction: Many patients because of ischemic heart diseases, cerbral or pulmonary diseases are not appropriate candidates for general anesthesia in upper limb surgeries. Intravenous regional anesthesia (IVRA) is one of the anesthetic procedures for these patients. The aim of this study was to compare the effects of adding Pancronium and Fentanly to Lidocaine during IVRA.
Materials and Methods: In a single-blind clinical trial investigation, 46 patients-who were candidated for hand surgeries-were studied. The subjects were randomly classified into two groups. The first group who used 38 cc Lidocaine 0.5% and 2 cc sterile water (control group) and the second group who used 38 cc Lidocaine 0.5% besides 50 mgr Fentanyl and 0.5 mgr Pancronium (trial group) for sensory and motor blacking. Data analysis was performed by t-test through SPPS 10 software.
Results: The average time for storing of sensory and motor block in trial group was significantly faster than control group. Additionaly, the average time for starting of sensory and motor block in control group was significantly lower than trial group.
Conclusion: This study revealed that adding of Fentanyl and Pancronium causes better motor and sensory block and provide better relaxation for muscles during surgery.

Abstract
Introduction: Laryngoscopy and intratracheal intubation are one of the most painful and stimulant procedures with a severe autonomic responses. This research was performed to investigate affects of xylocaine and sufentanil on blood pressure and herat rate due to laryngoscopy and intratracheal intubation.
Materials and Methods: This research was performed on 100 patients in ASA class 1,2 which were condidated for elective surgery. Patients were divided into two equal groups. For first group xylocaine 1.5mg/kg was injected 90s before laryngoscopy and the second received 0/2 mcr/kg sufentanil 120s before that, then laryngoscopy and intratracheal intubation was performed. Maintenance of anesthesia was the same for two groups. Herat rate and blood pressure were measured from the beginning of the laryngoscopy till 9 minutes after that, with three minutes interval.
Results: Finding showed that in the time of laryngoscopy, sufentanil and xylocaine had equal affects on hemodynamic changes. Also there was no significant difference between two named drugs on diastolic pressure. But in the third, sixth and ninth minute after laryngoscopy sufentanil controlled systolic blood pressure and heart rate significantly better than xylocaine.
Conclusion: Findings of this survey showed that sufentanil could manage hemodynamic changes due to laryngoscopy and intratracheal intubation netter than xylocaine. with due attention to low side effect of sufentanil. It is suggest to use this drug for high risk patients.

Abstract
Introduction: Postoperative shivering is a common and unpleasant problem with relatively 40% incidence that has a lot of cardiovascular and pulmonary effects. Its main cause is hypothermia during operation. But there are also other causes. There are some recommendations to resolve this problem. In this survey we compared tramadol and pethidin effects in treatment of postoperative shivering.
Materials and Methods: This is a clinical trial study, performed on 324 patient with ASA I and II classes. When shivering occurred, 1mg/kg tramadol was administrated to 162 patients and the others received 0.5 mg/kg pethidin. After injection, the shiver-end time was recorded. Patients vital sign such as blood pressure, pulse rate and respiratory rate were measured and recorded before and after injection (vital sign was checked and recorded every 10 minutes for 1 hours after injection). Data was analyzed with two independent t-test by SPSS software.
Results: 61.7% of samples were male. The average of shiver-end time in group receiving tramadol and group receiving pethidin was 134.96±18 and 161.3±22 seconds respectively, that was significantly lower in tramadol group (p=0.007). The minimum of shiver-end time was 55 seconds in patients receiving tramadol and the maximum time was 320. The minimum of this time in patients receiving pethidin was 70 seconds and the maximum time wad 395.
Discussion: Results of this study showed that using tramadol in treating postoperative shivering is more useful than pethidin. Also it has better therapeutic effects and lesser side effects.

Abstract
Introduction: Postoperative nausea and vomiting is one of the most common problems in postoperative period. Patients' who are at high risk of PONV, may receive anti-nausea and vomiting drugs. The most common drug is Metoclopramide, but it,s extrapiramidal signs and side effects such as lethargy, dizziness and headache especially in children lead us to perform this study, in order to compare Dexamethasone and Metoclopramide effects in PONV prevention. Materials and Methods: This study was a double-blind randomized controlled clinical trial. 262 patients (2-25 years) in ASA class I,II which were candidates for ENT, eye and laparatomy surgeries, divided into two groups randomly. One group received 0.1 mg/kg Dexamethasone IV and the other group received 0.1mg/kg Metoclopramide IV, 10-15 minuets before operation ending time. During recovery, the frequency of PONV was assessed. Data was analyzed by Pearson test. Results: PONV frequency in the two groups had no significant difference. Also PONV rate in the two groups had no significant difference in male and female. Conclusion: In prevention and treatment of PONV, Dexamethasone effect was same as Metoclopramide. Considering low expense, avalibility and low side effects, Dexamethasone is a proper substitute for Metoclopramide in surgeries with high risk of PONV.

Abstract
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.

Abstract
Background: Helicobacter pylori iceA gene has been reported to be a genetic marker for the development of peptic ulcer in western populations. The aim of this study was to investigate the prevalence of iceA genotypes and their relationship with peptic ulcer in Iran. Materials and Methods: This observational study was carried out on 75 patients. Biopsy specimens were evaluated for the presence of Helicobacter pylori through rapid urease test. GlmM gene and iceA1 and iceA2 genotypes allelic verification and variation culture were determined via PCR. Results: In this study, iceA1 and iceA2 alleles were identified in peptic ulcer disease (PUD) patients. IceA1 genotype (64%) was more prevalent than iceA2 (21.3%). IceA1 strains were more observable in patients with PUD. No significant relationships were seen between iceA genotypes and the clinical outcomes following infection (p= 0.71). Conclusion: This study revealed a significant two-tailed correlation between iceA genotypes and PUD occurrence. The results indicate that iceA1 gene can be used as a reliable marker in predicting the clinical outcomes of Helicobacter pylori infection. Therefore, further in-vitro and in-vivo investigations are needed for reaching general consensus in this regard.

Abstract
Background: Today, there is growing interest in using traditional medicine for healing cutaneous wounds. Probiotics are defined as different microorganisms that may have positive effects on prevention or treatment of special pathologic conditions. The present study was designed to investigate the effect of Lactobacillus brevis on cutaneous wound healing.
Material and Methods: In this experimental study, through phenol-sulfuric acid method, 22 strains of lactobacillus isolated from dairy-traditional products were investigated in terms of exopolysaccharide production. Lactobacillus brevis, which had high exopolysaccharide (EPS) production, was selected. A wound was created on the back of male Wistar rats in control, negative control, and experimental groups. Control and experimental groups underwent regional treatment by eucerin and eucerin contained Lactobacillus brevis, respectively, but the negative-control group did not receive any treatment. On days 1, 7 and 21, the rats were killed and their cutaneous wound samples were studied. Data analysis was done through SPSS version 11.5.
Results: The percentage of wound healing (99.53%) and inflammation in the experimental group on day 21 compared to control (90.55%) and negative groups (91.14%) was significantly higher (P<0.001). The number of neutrophils in the experimental group decreased in later phases of wound healing compared to the control and negative control groups.
Conclusion: The present study showed that Lactobacillus brevis significantly decreases inflammation and accelerates wound healing in treated rats. The findings of this study can be applied clinically in near future

Abstract
Background: Oxidative stress and severe neuro-excitation have significant effects on pathogenesis of Parkinson’s disease and agents with antioxidant property can potentially prevent these effects. Herein we examined potential protective effects of melatonin as an antioxidant agent and memantine as an uncompetitive receptor of NMDA, on a model of Parkinson’s disease induced by 1-methyl-4-phenyl-1, 2, 3, 6-tetrahydropyridine (MPTP).
Materials and Methods: Male mice were divided into 8 groups with 7 mice in each group: saline, ethanol, melatonin, memantin, MPTP, melatonin+MPTP, memantin+ MPTP, melatonin+ memantin+ MPTP. All of agents were injected intraperitoneally once a day for 14 days before beam traversal test. Dopaminergic neurons of the Substantia Nigra Pars compacta (SNPC) were determined by immunohistochemical and were counted.
Results: Melatonin improved notably movement dysfunction resulted of MPTP such as the number of errors, paces and the time of movement during behavioral test and also the counting of neurons of Substantia Nigra Pars Compacta. Memantin had a synergic effect on the most of improvements. However, the level of improvement and retrieval of signs was not as in saline and ethanol groups.
Conclusion: Melatonin especially together with memantine is able to prevent some of the MPTP-induced dysfunctions. However, the protective effects were not enogh, probably because of the amount of dose and the time of injection.

Abstract
Background: Multiple sclerosis (MS) is a chronic inflammatory disorder described by central nervous system (CNS) demyelination and axonal damage. While the cause of MS is still unknown, it is extensively accepted that novel drug targets need to attention. Retromers are protein complex that have an essential role in endosomal trafficking, and retromer dysfunction has been associated to several neurological disorders. Therefore, this study aimed to compare the expression of SNX2 gene as a part of retromer complex in MS patients with health individuals.
Materials and Methods: In this case-control study, 50 samples of cases of multiple sclerosis (MS) and 50 healthy controls were enrolled. Followed verifying disease, 3cc peripheral blood was given from all subjects. Total RNA was extracted and complementary DNA (cDNA) was synthesized. The relative gene expression was determined using quantitative real-time RT PCR (qRT-PCR) and evaluated by 
method.
Results: The expression of SNX2 gene was lower in MS patients compared with healthy controls and it was statistically significant (p< 0.05).
Conclusion: Our study showed that the expression of SNX2 is lower in multiple sclerosis disorder. Considering the functional role of SNX2 as a protein involved in trafficking process, SNX2 may affect receptor function or drug targeting. Therefore, supplementary studies should be done to elucidate the exact mechanism of action of the gene in cellular trafficking.

Abstract
Background: Adipose tissue's phenotypic alteration due to exercise training is a new theory. However, the cellular–molecular mechanisms for these phenotypic alterations are not yet clearly
understood. The aim of this study was to investigate the effects of six weeks resistance training on Meteorin-like hormone level and insulin resistance index in overweight adolescent boys.
Materials and Methods: Twenty overweight adolescent boys (average age 18.5±1 years old, average weight 81.1±4.5 kg, and BMI 27.7±0.7 kg/m2) participated in this study. The subjects were randomly assigned into two groups: control (N=10) and resistance training (N=10). Subjects in training group performed six-week resistance training program 3 days/week. Anthropometrics parameters and fasting serum of Meteorin-like hormone levels, insulin and glucose were measured at the baseline and at the end of study.
Results: The level of Meteorin-like hormone was significantly decreased in control group (p=0.008), but that of Meteorin-like hormone in resistance training was increased insignificantly (p=0.311). The variations of Meteorin-like hormone levels between two groups were significant (p=0.004). The changes of insulin resistance were increased in both groups which were statistically significant (p=0.032) and insignificant (p=0.632) for control and training groups respectively. We found a negative and insignificant correlation between changes in Meteorin-like hormone levels and changes in insulin resistance index (p=0.273).
Conclusion: The results showed that six weeks’ resistance training has no effect on increasing Meteorin-like hormone serum level and improving insulin resistance index and body composition in overweight adolescent boys.

Abstract
Background: Lipases are one of the groups of enzymes which are important in medicine and industry. In gastrointestinal tract of human, lipase catalysis break down of triglyceride. Bacteria have also lipases which break down triglyceride in their culture medium and can use its fatty acids as carbon source. Dicyclomine is an antispasmodic drug that relieves smooth muscle spasm of the gastrointestinal tract. Few drugs have been determined to inhibit lipase activity, in this research; dicyclomine was introduced as an inhibitor of lipase, for the first time.
Materials and Methods: Lipase was extracted from Pseudomonas aeruginosa and the effect of dicyclomine was tested on its activity. The bacterium was cultured in medium with olive oil as carbon source and the supernatant was used for enzyme assay. For monitoring the enzyme activity, Para nitrophenyl palmitate (pNPP) was used as a substrate and the induced product was measured by visible spectrophotometer. Lineweaver-Burk plot was utilized for revealing the type of binding.
Results: This research has shown that dicyclomine can inhibit lipase. Inhibition plot determined that the drug can inhibit the enzyme by competitive manner. Calculation of Ki and IC50 values showed that the drug can bind to the enzyme with high affinity. The study of enzyme activity in different pH and temperature revealed that optimum activity of enzyme, in the presence or absence of the drug, was observed in pH 8 and 60oC.
Conclusion: For the first time, dicyclomine was introduced as an inhibitor of lipase and the kinetics factors of the drug were investigated.

Abstract
Background: and Aim The leachate from oil sludge compost into the environment, which is resistant to decomposition, causes several environmental problems. Therefore, it needs to be treated using efficient processes. This study aimed to investigate the efficiency of the modified Fenton process for treating these oil sludge leachates.
Methods & Materials: In this experimental study, leachate samples were collected, and then modified Fenton solution was prepared by adding Fe2 (SO4) 3 to H2O2. Then the effect of time parameters (15, 30, 60, 90, and 120 minutes), modified Fenton concentration of 20, 50, 100, and 200 mg/l with pH 3, 5, 9, and three initial concentration of COD (500, 1000 and 1500 mg/l) was examined.
Ethical Considerations: This study has been registered in Arak University of Medical Sciences with codes 2645 and 2765.
Results: The reduction of COD and TPH in the optimal time of 60 minutes, initial COD of 500 mg/l, pH of 3, and Fenton concentration of 200 mg/l were 9.04 and 77.42%, respectively. The experiments showed that the removal efficiency of COD and TPH with increasing residence time and the concentration of modified Fenton are directly proportional and with decreasing, the initial concentration of COD and pH is inversely proportional.
Conclusion: The use of modified Fenton is an efficient method for treating leachate from petroleum sludge compost.

Abstract
Introduction: Salmonella infection (salmonellosis) is a common bacterial disease that affects the intestinal tract. Several methods like Multiplex or real-time PCR, ELISA, and Agglutination are used to identify these bacteria. However, normally rapid, cost effective and easy diagnostic methods such as agglutination test is recommended. In Iran, positive control antiserums used in diagnostic kits work based on polyvalent agglutination and are against O and H antigens. The purpose of this research was to produce specific anti-sera against O and H antigens for using in agglutination and ELISA kits.
Methods: New Zealand white rabbits were immunized by intravenous injections of inactivated bacterial O and H antigens adjusted to a cell density equivalent to a turbidity of a McFarland number 3 standard. Serum collection was performed 7 days after the last injection. Collected Antisera were tested with positive human specimens as well as cross-reaction antibodies. Absorption method was used to obtain specific anti-sera against O and H antigens. Produced Anti-O and Anti-H antibodies were mixed with bacterial H and O antigens respectively and incubated for 1 hours in 37˚c. The Mixture was centrifuged and the supernatant was collected. Furthermore, in order to use these antisera in specific kits such as ELISA, Immunofluorescence etc., purification methods like Ammonium sulphate precipitation, tangential Flow Filtration and Chromatography were performed. This study was approved by the ethics committee of Pasteur Institute of Iran (Code: IR.PII.REC.1399.006).
Results: Results of agglutination test before and after adsorption showed cross-reaction before adsorption and no cross-reaction with H and O antigens with monospecific antisera against O and H after adsorption, respectively. Moreover, high quality and quantity of mono-specific antibody was obtained after purification.
Conclusions: Serum-based assays are recommended for the timely diagnosis of the disease since these assays are specific, sensitive, inexpensive, and rapid. Therefore, the produced antiserum in the present research can be used in primary screening of salmonella infections based on agglutination tests which are cost effective and simple. In addition, purified anti-sera can be used in the development of ELISA and Immunofluorescence assays.
