  Paraplegia can be caused by different factors like rupture or repair of the aortic aneurysm or aortic thrombosis, aortic dissection, anterior spinal cord artery emboli, coagulation disorders and lupus disease, all of which cause impaired spinal cord blood flow and spinal cord ischemia. In addition, hypotension may be the cause of spinal cord infarction but Medline researches have reported a few cases of spinal cord infarction in patients laparotomized for the reasons other than aortic lesions. In this paper we report one case of paraplegia who had experienced spinal infarction and paraplegia after internal bleeding and two times laparatomies due to long lasting hypotension. In this case regarding the patient ’ s age, occupation and physical health, the possibility of cardiovascular lesions and consequent thromboembolism seems very unlikely. Furthermore, considering the two operations performed and the temporal space between them, the only factor that could have led to ischemia and infarction of the spinal cord in this patient is long-standing hypotension.

Background & Objectives: Venous thromboembolism is a common disorder that is difficult to diagnose clinically but carries significant mortality if untreated. Many diagnostic imaging algorithms for the detection of PTE, including ventilation perfusion lung scan, Doppler ultrasonography of lower extremity and pulmonary CT angiography. This study's aim was the comparison of Doppler ultrasonography of lower extremity with perfusion -ventilation lung scan in patients suspected for pulmonary emboli and finding the best approach for diagnosis of the suspected pulmonary emboli.
Methods: One hundred twenty patients of suspected pulmonary embolism referred by internists to Doppler ultrasonography of lower limbs Department of Imam's Khomeini Hospital were studied. The patients were studied within 48 hour post suspected pulmonary emboli and evaluated with V/Q scan and Doppler ultrasonography.
Results: The prevalence of DVT in lower limbs of patients suspected of pulmonary emboli was %37.5. Results of lung scan in patients suspected pulmonary emboli are as below: High probability in %17.5, intermediate probability in %27.5, low probability in %41.5 and normal in %13.5 Results of lung scan in patients suspected  for pulmonary embolism with DVT are as follow: High probability in %24.4, Intermediate probability in %33.3, low probability in %26.7 and normal in %15.6. Mean age in patients with and without DVT Was 52.53 14.13 and 56.22 17.63 year respectively.
Conclusion: Patients suspected for pulmonary emboli with normal lung scan needs more assessment for DVT in lower extremity with Doppler ultrasonography. Normal Doppler ultrasonography of lower extremity doesn't exclude performing lung scan for approving pulmonary emboli. Doppler ultrasonography and lung scan both need evaluating patients suspected for pulmonary embolism.

 Background & Objectives: Intensive care unit (ICU) is one of the most critical parts of the hospital. In other words the intensive care means taking care of patients suffering fram acute and life-threaning diseases by the most expert personnel, using modern equipment and facilities. The purpose of this study was to evaluate the mortality rate of the patients admitted to ICU and the effective factors in at Ardabil Fatemi Hospital.

  Methods: This is descriptive-cross sectional study carried out on the patients admitted to surgical and neurosurgical ICU in Ardabil Fatemi Hosbital from June 2005 to June 2006. Among all the patients admitted to ICU (903 patients) who were under investigation, only those who died were included in the study. The effective factors were age, gender, previous sickne type of illness, complications, ventilator connection requirment. The information collected using the questionnaire and the data were analyzed with spss and chi square statistical programs.

  Results: From the total namber of 903 patients admitted to ICU 140 (15.5%) of them died. According to the information collected 72.8% of the cases were male and 27.2% were female. The age range of pateints was 10-80 years old. The mortality rate was high among the patients over 60 years old. The second one was 21-30 years old. The highest mortality rate was observed in the first five days of admission to the ICU 92.8% of these patients were being ventilated, 48.5% had a history of underlying diseases and 33.5% were afflicted with CNS trauma.

  Conclusion: Accordig to the findings, there was a significant relationship between traumatic patients and the mortality rate. The CNS trauma was the most prevalent factor of death in ICU. It is also noticeable that the mortality rate was higher in males and the old age group.

Background & objectives: In recent years, Acinetobacter baumannii has been shown to be associated with several nosocomial infections, including pneumonia, bacteraemia, urinary tract infections, wound infection and meningitis. This organism can survive in the hospital environment and rapidly develops resistance to many antibiotics. The molecular genotyping can increase our knowledge about the spread of A. baumannii strains from one hospital to another and their drug resistance. Therefore, this study aimed to determine the prevalence of antibiotic resistance profile as well as phylogenetic relationships of A. baumannii strains in Shahrekord teaching hospitals.
Methods: In this study, antibacterial susceptibility patterns of A. baumannii strains isolated from different clinical specimens (urine, blood, sputum) to amikacin, ampicillin/sulbactam, aztreonam, cefepime, ceftazidime, ciprofloxacin, gentamycin, imipenem, meropenem, norfloxacin, ofloxacin, piperacillin/tazobactam, tobramycin were tested using disk diffusion )Kirby-Bauer( method. Finally, genotyping of A. baumannii strains was performed using REP-PCR method.
Results: During this study, 50 samples of patients were identified as A. baumannii) 71%(, and their drug resistance rates were assessed. All A. baumannii strains were resistant to ceftazidime and cefepime and also a high rate of resistance to aztreonam, norfloxacin, ciprofloxacin, amikacin, imipenem, gentamycin, and ampicillin-sulbactam were observed. On the other hand, our results demonstrated nine genotype groups among A. baumannii strains based on REP-PCR method.
Conclusion: Due to the high prevalence of antibiotic resistance among isolated A. baumannii strains, similarities between different genotypes and the dispersion of these genotypes in different parts of Shahrekord hospitals, the implementation of infection control programs in different parts of the hospital is necessary.

Background & objective: FoxO1 and STRA13 proteins play an important role in duplication and cellular metabolism, regulation of cell differentiation, apoptosis and reducing the spread of fat tissue in the body. The aim of this study was to investigate the effect of different intensities of aerobic training on the expression level of FoxO1 and STRA13 genes in subcutaneous adipose tissue of male Wistar rats.
Methods: In this experimental study, 32 male Wistar rats with a mean age of 8 weeks and weight of 237±33 gr were selected, and they were randomly divided into 4 equal groups including moderate-intensity aerobic training (MIT), high-intensity aerobic training (HIT), high-intensity interval aerobic training (HIIT) and control group. The training program was implemented 8 weeks and 5 sessions per week for the experimental groups,. Adipose tissue biopsy was performed 48 hours after the last training session to evaluate FoxO1 and STRA13 gene expression using  RT-PCR method. Data were analyzed using One-way analysis of variance test using SPSS 24 software at the significance level of p<0.05.
Results: The results showed that there was a significant difference in the FoxO1 gene expression level in the subcutaneous tissue of male Wistar rats between HIT and control groups (p=0.0001). However, no significant difference was observed between experimental groups. In addition, there was a significant difference in STRA13 gene expression level in the subcutaneous tissue between MIT (p=0.008), HIT (p=0.0001) and HIIT (p=0.009) groups and control group.
Conclusion: According to the results, aerobic exercise with variety of intensity is effective in controlling the genes expression rate involved in fat metabolism and by reducing the FoxO1 and STRA13 genes expression, they cause the duplication and reduce the expansion of fat tissue.
