Background: Accuracy of different methods of magnetic resonance imaging for detection of knee lesions is still questionable. This study was aimed to compare the accuracy of intraarticular contrast enhanced magnetic resonance arthrography and intravenous contrast enhanced magnetic resonance arthrography for detection of knee lesions.Materials and Methods: Twenty five patients who had knee lesions and candidated for diagnostic and treating arthroscopy were entered to the study. The intraarticular contrast enhanced MR and intravenous contrast enhanced MRI has been performed for them. The results of imaging has compared with findings of arthroscopy as a gold standard for calculation of each test sensitivityand specificity and the overall accuracy of each method.Results: The calculated sensitivity, specificity and overall accuracy for intraarticular contrast enhanced in respect for MM is 87%, 100%, 88% and LM 77%, 91%, 84% and ACL 84%, 100%, 88% and PCL 88%, 93%, 92% and about the intravenous contrast enhanced in respect for MM is 48%, 100%, 52% and LM 0%, 100%, 44% and ACL 84%, 100%, 88% and PCL 30%, 100%, 72%. Comparing of overall accuracy of 2 methods has shown that replacement of intravenous contrast enhanced MR for intraarticular contrast enhanced MR is just acceptable for ACL and PCL lesions (P=1.000, P=0.063).Conclusions: We demonstrated that the overall accuracy of intravenous contrast enhanced MR for detecting of ACL and PCL lesions is comparable with intraarticular enhanced MR and both methods could be used as each other.

Background: Matrix metalloproteinases (MMPs) plays a role in the several physiologic and pathologic events. There is some evidence indicating the involvement of MMPs in tumor invasion and inflammatory diseases. In this study we evaluated the effect of cell wall candida albicans fraction on MMP production by the fibrosarcoma cell line using an in vitro cytotoxicity assay, sodium dodecyl sulfate-polyacrylamide, and gelatin zymography.Material and Methods: It was an experimental study. Fraction of cell wall candida albicans was extracted by lysis buffer and 0, 10, 50, 100 (mg/ml) from fraction was added to human fibrosarcoma cell line in 96 well microplate and inhibitory effect on tumor cell invasion was investigated by MTT and zymography test.Result: Our results showed that fraction of cell wall candida albicans was found to exhibit a inhibitory effect on tumor cell line in MTT test because the viability of tumor cells was decreased versus the control groups. Also the production of metalloproteinases enzyme in presence of fraction was diminished significantly (P<0.05).Conclusions: Since inhibition of MMP activity has been employed in modality therapy in diseases such as cancer, this fraction could be promised in the preparation of anti-MMP therapeutic derivatives.

Background: Forward head posture (FHP) is one of the most common faulty postures to be accompanied by the deep neck stabilizer muscle weakness. Physiotherapists usually recommend using the chin-tuck exercises to correct this faulty posture. This study has been designed to examine the effect of added stabilizing exercise to the Chin-tuck exercise on FHP correction.Material and Methods: It was a quasi-experimental study. Forty seven university female students who had FHP, were assigned randomly in one of two comparison groups, an experimental group (receiving combined intervention of chin-tuck and stabilization exercises, n=24) or a control group (receiving only the chin-tuck exercise intervention, n=23). Participants were completed their exercise protocol twice daily for four weeks. The amount of forward head displacement was measured before and immediately after four weeks' intervention and after three months' follow-up too.Results: After intervention, significantly decreased in the FHP was seen in both experimental (mean=2.1 cm, P<0.0001) and control (mean=1 cm, P=0.03) groups. The comparison of the mean changes of forward head displacement between groups indicated the significantly more FHP correction in the experimental group immediately after intervention (mean difference=1.1 cm, P=0.001) and also after a three months follow-up periods (mean difference=1.7 cm, P<0.0001), compared to the control group.Conclusion: Our results showed that the combination of stabilization exercises and chin-tuck exercises provide not only the better correction effect for FHP patients, but could be provided a more effective and stable corrected posture. More study might be needed to investigate the effect of single stabilization exercise protocol on the forward head posture correction.

Background: In Patients with Chronic kidney, hypertension can be transferred to the glomeruli and influence proteinuria. Physical activity seems to effects on the Amount of blood pressure and the increase albumin protein. The study has been conducted to determine the effect of 8 Week Running on Treadmills on the Amount of blood pressure and the excreted albumin protein in Patients with Chronic kidney.Materials and Methods: It was a quasi-exprimental study. The study sample includes: Twenty seven subjects were chosen male Patients with chronic kidney disease (groups of control 15 and experimental 12 subjects). Regarding their age and the amount of their Glomerular filtration, they were relatively matched and were divided into two groups of control and experimental. An exercising program was given to the experimental group including 8 week running on treadmills with the intensity of 50-80% maximal heart rate, which was practiced thrice a week, each session lasting 30-40 minutes. After the end of the exercising period, blood and urine tests were taken from both control and experimental groups under the same condition.Results: Meaningful differences was perceived in the amount of diastolic blood pressure between control and experimental groups after 8 Week Running on Treadmills (P=0.001), The serum albumin rate (p=0.8) and ratio of protein to Cr excretion in 24 hour urine (p=0.7).Conclusion: Aerobic activity can be an effective measure to control blood pressure and slowed development of renal disease progression and prevent renal complications of hypertension outside cardiovascular disease is like.

Background: Acute coronary syndrome is a collection of symptoms that could be different in female and male due to their differences in the physical or psychological and cultural differences subjects. This study was aimed to compare the clinical symptoms of chest pain and acute coronary syndrome in women and men hospitalized in the intensive coronary care units.Material and Methods: In this cross sectional study the pain characteristics and clinical symptoms of acute coronary syndrome of admitted patients to the coronary intensive care units were compared. We helped as the questionnaire and McGill Pain Scale as studied research instrument. Data was analyzed by SPSS software with Chi-square test, t test and calculation the odds ratios and confidence intervals.Results: The pain by women has more chance to occur in the other places other than chest. Being a woman enhances the chance of experiencing the heart palpitations, anorexia, nausea, indigestion, shortness of breath and sweating would whereas men were more likely to feel vomiting. Bloating, hiccup, fainting, dizziness and anxiety were similar in both sexes.Conclusion: Women have showed the different symptoms than men, so more attention to women's health is important dealing with these symptoms.

Background: Burnout is one of the most important factors in the reduced productivity in the organizations that involved the physical and mental signs. The purpose of this research is to explore the relationship between job stress and burnout with productivity in pilots.Material and Methods: A descriptive cross-sectional survey was conducted among 150 selected pilots by random cluster sampling. To acquire the necessary data, questionnaires on El raise the job stress and Maslach job burnout and productivity were used. For data analysis the Pearson's coefficient of correlation and regression were used.Results: Results showed the meaningful relation between the productivity with job stress, the emotional exhaustion and the depersonalization. The emotional exhaustion and inadequacy were great share predictor productivity.Conclusion: There was the meaningful relation between the job stress and burnout with productivity. Also we found that the life learning skill could be increased the productivity.

Background: Vitamin C deficiency is a common in hemodialysis patients. Evidences indicated that oxidative stress is associated with Vitamin C deficiency. Oxidative stress plays an important role in the progression of anemia, uremia and hypertension in the patients with chronic renal failure that receiving hemodialysis. The purpose of this study was to determine the vitamin C effects on systolic blood pressure, hemoglobin, hematocrit, blood urea and creatinine.Material and Methods: In a randomized clinical trials with registry number IRCT:2387 in Emam Reza and Besat University Hospitals in 2009, fifty six hemodialysis patients who met the inclusion criteria were selected by simple randomization method. These subjects were divided in two groups randomly: The experimental group who received oral vitamin C 250 mg, three times per week until two months. The amounts of blood pressure, hemoglobin, hematocrit, blood urea and creatinine tests were compared before and after the intervention. Finally the results were analyzed statically with T test by considered P-value less than 0.05.Results: The level of hemoglobin and blood pressure was higher in experimental compared to control not significantly. While the blood urea and creatinine was insignificantly lower after intervention. These results show a statistical significance difference due to increasing of hematocrit level by using of oral vitamin C (P<0.05).Conclusion: There is association between supplementation with oral vitamin C in hemodialysis patient and systolic blood pressure, hemoglobin, hematocrit, blood urea and creatinine. Therefore further studies are needed to determine the clinical benefits of antioxidants interventions in hemodialysis patients.
