Abstract
protozoan of Leishmania genus and in Iran by Leishmania infantum. The protective immune response against VL is cellular immunity through Th1 CD4+, which dominant chemokiens are IL12, IFN- γ and IL18 and lead to Th1 response. Single nucleotide polymorphism (SNP) on IL-18 gene and its relation to IL18 levels in blood and IL18 function have been studied in many inflammatory diseases such as Behcect’s disease and tuberculosis. According to the important role of IL-18 in immunity against visceral leishmaniasis, this study was conducted to demonstrate the prevalence of genotypes on -607A/C in promoter region of IL-18 gene.
Materials and Methods: This descriptive and cross-sectional study was done on 91 pateints with confirmed VL, 105 healthy sero-negative controls and 78 seropositive controls during 1999-2009. Salting out method was used to extract DNA and ARMS-PCR was used to determine the genotype of -607A/C allele of individuals. Statistical analysis of genotypes was performed using Chi-Square test.
Results: According to the results, -607C/C was the dominant genotype among the groups (35.8%). Distribution of genotypes among groups had not any significant difference. The lowest genotype among healthy sero-positive and patients were -607A/C and -607A/A, respectively. Statistical analysis of distribution of genotypes, did not reveal any significant difference among groups.
Conclusion: The dominant genotypes of VL patients, healthy sero-negatives and healthy sero-positives were -607C/C (38.5%), -607A/C (37.1%) and -607C/C (35.9%) respectively.

Abstract
Background and Objective: Legg-Calve-Perthes disease is one of the most common disabling diseases of childhood and if not managed appropriately is truly disabling. Severity of disease and duration of disease onset are main determinants of choosing treatment strategy of either conservative management or surgical treatment. This study was designed to determine Legg-Calve-Perthes treatments and relation between type of treatment and duration of the disease.
Materials and Methods: This descriptive study was carreid out on 50 patients with Legg-Calve-Perthes disease admitted in Ghaem Hospital in Mashhad, North East of Iran from 1995-2005.
Results: According to age of patients and severity of disease, the subjects allocated to conservatine (11 patients) and surgical treatment (39 patients). Clinical improvment signs include pain reduction, range of joints motion, which were avaluate by physical examination and taking medical history of patients. In conservative group, only 4 patients assumed to be successfully treated with mean age of 7.25 years and the mean interval between disease onset and beginning of treatment was 2.25 months. Surgical group had mean age of 10.85 years and mean interval between onset of disease and initiation of treatment was 18 months. Conservative group showed less sever form of disease (lateral pillar group A and group B with age less than 8 years), but patients treated surgically were more severely involved (lateral pillar group B with age more than 8 years and group C).
Conclusion: This study showed that age and severity of disease (lateral pillar classification) are main elements in treatment strategy (choosing conservative VS surgical treatment). The interval between onset of disease and onset of treatment strongly affects treatment success.

Abstract
Background and Objective: Abdominal operations as gynaecological procedures result in gastrointestinal dysmotility. Early feeding and ambulation are nonpharmacologic interventions which can be useful in re-initiation of bowel function. This study was done to evaluate the effect of early oral hydration on the return of bowel function and woman's satisfaction after elective caesarean section in primiparous women.
Materials and Methods: In this randomized clinical trial, 120 primiparous women undergone elective cesarean section were assigned to control and intervention groups in Hajar hospital, Shahrekord, Iran during 2007. In the interventional group, oral hydration with liquids was started 4 hours after surgery regardless of presence of bowel sounds and solid food was started after bowel sounds appeared. The control group recieved liquid diet 12 hours after the operation if it was tolerated, they were given soft diet and regular food at the next meal. The return of bowel activity, time of ambulating, satisfaction, discharge from the hospital and complications were compared in two groups. The data were analyzed using SPSS-15, Chi-Square, T and one way ANOVA tests.
Results: The mean postoperative time interval to first hearing of normal intestinal sounds in interventional versus control groups were (9.5±1.38 and 12.5±2.5 hours) the first passage of flatus (15.7±3.61 vs.22.4±4.1 hours), time to first sensation of bowel movement (10.8±1.99 versus 15.7±3.4 hours) and defecation (18.9±3.65 versus 23.4±4.85 hours). These differences were significant (P<0.05). Also discharge from the hospital (0.96±0.18 versus 1.1±34 days) were significantly shorter in interventional group (P<0.05). The women in the early feeding group got out of bed (patient mobilisation) earlier than their interventional group (14.1 hours versus 18.8 hours (P<0.05). Maternal satisfaction was significantly higher among the early fed women (P<0.05).
Conclusion: Early oral hydration after elective cesarean section associated with rapid resumption of intestinal motility and increased woman’s satisfaction.

Abstract
Low back pain (LBP) is a common and complicated disorder which is influenced by a number of factors, among them is the lack of spinal stability provided by muscle contraction. One of the most important muscles which has a role in spinal stability is musculus transversus abdominis. A literature search for the period of 2000-11 was performed in PubMed, ProQuest, Science Direct, Thomson, EMBASE, OVID, CINAHL and MEDLINE databases using musculus Transversus Abdominis, ultrasonography, chronic nonspecific low back pain as keywords. Nineteen articles were selected according to the inclusion criteria of the study. Evidences demonstrated that thickness of transversus abdominis reduces in patients with chronic nonspecific low back pain (LBP) and ultrasonography seemed to be a valid and highly reliable instrument for measuring thickness of transversus abdominis in patients with LBP and healthy subjects on different positions and states. Studies demonstrated that there are adequate evidences to confirm the merit of ultrasonography in the assessment of musculus transversus abdominis in patients with chronic LBP and healthy subjects.

Abstract
Background and Objective: Pollution due to the heavy metals is a problem that may have negative consequences on the hydrosphere. Identification of microorganisms resistant to heavy metals plays an important role in relation to environmental pollution bioremediation. This study was done to assess the antibiotic resistance in isolated bacteria from urban sewage and copper smeltery industrial wastewater. Materials and Methods: This laboratory study was done on the wastewater samples from urban sewage and copper smeltery in Isfahan-Iran, during 2011-12. Heavy metal resistant microorganisms were isolated and enumerated after serial dilution and culturing on PHG agar plates supplemented with 0.5 mM of each heavy metal. The pattern of resistance was assigned by Minimum Inhibitory Concentration (MIC). Antibiotic resistance toward following medicines Ofloxacine, Penicilline, Sulfometoxasole, Lincomycin, Kanamycin, Streptomycin, Clindamycin, Vancomycin, Cefradin and Neomycin were subsequently investigated. Results: The greatest resistance in isolated bacteria has been related to the Ni (MIC: 24 mM) that’s related to the genus of Klebsiella and its minimum MIC is 2mM that’s of Acinetobacter lwoffi, Providencia stuartii, Branhamella. The minimum degree of resistance is related to Cu. Its Maximum MIC related to this metal in swage is 2 mM that’s of Klebsiella pneumoniae and its minimum degree of resistance in copper smeltery effluent is arranged as 1mM related to genus of Pseudomonas alkaligenes. In examining multi metal resistance pattern, the greatest resistance with 8 mM MIC has been related to the Cd, that’s of Ni resistant Moraxella osloensis in Copper smeltery effluent. The highest portion of isolated bacteria were resistant to Pb (P<0.05). The highest resistance of refirary wastewater was to Ni (MIC: 2 mM), which belong to Klebsiella (P<0.05). The lowest belong to Acine to bacter Lwoffi providencia Stuartii, Branhamella (MIC: 2mM) (P<0.05). In urban sewage: the highest resistance belong to copper, which was seen in Klebsiella Pneumoniae (MIC: 2mM). In Antibiogram tests of Klebsiella, Moraxella and Escherichia, it was demonstrated that the metal resistant bacteria were also resistant toward Lincomycin, Kanamycin, Streptomycin, Clindamycin, Vancomycin, Cefradin and Neomycin, as well. Conclusion: Increasing heavy metal resistance in the environment leads to increased antibiotic resistance toward microorganisms.

Abstract
Background and Objective: Magnesium (Mg) ion has possible role in protecting neurons and glia from ischemic damage through the cerebral blood flow and neuronal action. This study was done to evaluate the correlation of total serum Mg level with clinical outcomes in stroke patients. Materials and Methods: This cross sectional study was done on 316 patients whom diagnosed with stroke in Imam Hossein hospital, Tehran, Iran during 2010-11. Mg levels in all patients were measured. Also, recurrent transient ischemic attack (TIA), recurrent myocardial infarction or stroke, unstable angina and death as clinical outcomes were follow-up for period of 3 and 6 months after admission. Data were analyzed using SPSS-18, Chi-Square, Fisher and Pearson correlation tests. Results: The mean age of patients was 65±15.8 year. Limb weakness (69.9%) and haemoplasia with 63.6% were the most common clinical complaints. Death was the most common finding in 3 month (16.8%) and recurrent stroke was the most common finding in 6 month follow up (2.5%). There was no significant difference between the total serum Mg and the first and second three-months follow up of clinical outcomes. Conclusion: This study can not show a significant correlation between total serum Mg levels and clinical outcomes after 3 and 6 month follow up in stroke patients.
