Abstract: 

Background: Traumatic spinal cord injury (SCI) is major permanent sequelae of trauma with high burden and low frequency. In the setting of SCI is there any correlation between the timing of surgical decompression and sensory-motor improvement.Material and Methods: A literature review was performed using PUBMED from 1966 to 25th January 2010. Cross referencing of discovered articles was also reviewed.Results: The results of animal studies have shown that aside from the kind of procedure and species, when compression is less severe and of shorter duration, the neurological and histopathological recovery is significantly good. One meta-analysis, nine prospective studies, and one randomized clinical trial were identified.Conclusion: There are presently no standards regarding the role and timing of decompression in acute SCI. As a practice guideline, early surgery in less than 24 hours can be done safely in patients with acute SCI and urgent decompression is a reasonable practice option. Traction is the most practical method of achieving urgent decompression after cervical SCI. There are class III data to support a recommendation for urgent decompression in any patient with incomplete SCI with or without neurologic deterioration, with or without bilateral irreducible facet dislocations. There is emerging evidence that surgery within 24 hours may reduce both the length of intensive care unit stay and incidence of medical complications.

Abstract: 

Background: Diabetes mellitus is a metabolic disorder as old as mankind and its incidence is considered to be high all over the world. Oxidative stress is strongly associated with development and the complications of diabetes. Antioxidant agents, especially with the origin of plants, are of more importance in the treatment of diabetic complications. The main objective of the present study was to evaluate the effect of extract of the grape seed on antioxidants status in streptozotocin induced diabetic rats.Material and methods: In this laboratory experimental study which conducted in Islamic Azad University of Tabriz research center. Forty male Wistar rats were randomly assigned into four equal groups including healthy control group, healthy group treated with grape seed extract (40 mg/kg), diabetic control group and diabetic group treated with grape seed extract (40 mg/kg). The experimental rats were treated in related groups for 12 weeks and at the end of experiment serum level of malonaldehyde (MDA) and anti-oxidant enzymes activity including superoxide dismutase (SOD), glutathione peroxidase (GPx) and catalase (CAT) were measured in red blood cells. Statistically, comparison of the groups was carried out using one-way analysis of variance followed by Bonferroni post-hoc test. Differences were considered statistically significant at p< 0.05.Results: Diabetic rats showed significant increase in the value of MDA and a decrease in the activities of SOD, GPx and CAT of red blood cells (p<0.001). Oral administration of grape seed extract resulted in significant reduction in the level of MDA and significant increase in the activities of SOD, GPx and CAT of red blood cells (p<0.001).Conclusion: The results of this study provide confirmatory evidence of oxidative stress in diabetes and show the anti-oxidative effect of grape seed extract.

Abstract: 

Background: Smokers have recently been shown to be insulin resistant and to exhibit several characteristics of the insulin resistance syndrome that could increase postprandial triglyceridemia. Postprandial hypertriglyceridemia could increase coronary artery disease (CAD) risk. In this study, we assessed fasting and postprandial triglyceride levels in healthy, normolipidaemic, chronic smokers and a matched group of nonsmoking individuals. Methods and Materials: We evaluated 78 subjects with simple sampling in case-control study. 39 were smoker and 39 nonsmokers. All of them had normal lipid and glycemic profile and had BMI between 19 and 29.9. The subjects didn’t have history of CAD or previously elevated fasting TG>150mg/dl, FBS>100mg/dl, age>60or<30, or alcoholic drinking. Then we give them 60 gm butter and triglyceride level was checked one and six hours postprandial. Between these times the subjects should not eat anything except water and smokers were allowed to smoke. All data analyzed with T-test and for repeated data ANOVA with SPSS software.Results: In our study was shown that TG levels among women and men had no significant difference (p=0.403). There was a significant difference among fasting TG, one hour postprandial and six hours postprandial in both groups(p<0.001). Also the changing rate of lipid from fasting state to one and six hours postprandial, among smokers and nonsmokers was significantly different (p<0.001).Conclusion: We concluded that smoking can change lipid profile in normolipemic subjects; and smokers with normal fasting triglyceride have more elevated levels of postprandial triglyceride in compared to nonsmokers.Postprandial hypertriglyceridemia has been an important factor for cardiovascular disease, then smoking can increase cardiovascular disease risk in this way.

Abstract: 

Background: Nowadays faster healing of surgical wounds is more challenging to researchers. The aim of the present study was to histopathological evaluate of the effect of rofecoxib, a non-steroidal anti-inflammatory drug, on healing of surgical wound in rats stomach.Materials and Methods: Sixty male Wistar rats were randomly assigned into three groups (control, positive control and experimental) of twenty animals each. A gastrotomy incision with the length of 1 cm was made in greater curvature of stomach in the rats, thereafter, sutured in 2 layers. Experimental group received rofecoxib (15 mg/kg) dissolved in Dimethyl Sulfoxide (DMSO) 5% (10 mL/Kg) daily for 15 days through the gavage. Positive control and control groups received DMSO 5% (10 mL/Kg) and normal saline (10 mL/Kg), respectively, in the same manner. Histopathological studies and comparison of wound healing among the groups were carried out considering more effective agents on wound healing including proliferation of fibroblasts, angiogenesis, re-epithelialization and collagen organization in healing tissue. Significant differences among the groups were determined by one-way analysis of variance followed by Bonferroni post-test. Statistical significance was considered at p<0.05.Results: The numbers of fibroblasts, capillary buds and organized collagen content in healing site of experimental group were significantly more than positive control and control group (p<0.001). The size of epithelial gap in experimental group was significantly lesser than two other groups (p<0.001). There were not any significant statistical differences between the control and positive control groups from the viewpoint of the above parameters. Conclusion: The results showed that rofecoxib possesses a beneficial effect on healing of stomach surgical wounds in rats.

Abstract: 

Background: Hepatitis E virus can be disseminated oral-fecally and its fulminant form mortality rate maybe up to 20% in the third trimester of pregnancy. This study aimed to assess the sero-epidemiology of HEV in women of reproductive age in Gorgan, Iran.Materials and Methods: In this cross-sectional descriptive study, 1200 women ages between 17-45 years were recruited from laboratories and health care systems of Gorgan. Demographic data was recorded in the checklists. ELISA method (DIAPRO) was done to evaluate the anti-HEV antibody. Data were entered into SPSS-13 software for analysis by Chi-squared and Fisher exact test.Results: Mean (±SD) age of the cases was 27.41 (±6.33). Among 1200 subjects, 76(6.3%) cases had positive anti- HEV antibodies. Age and ethnicity had a significant relationship with HEV (p-value<0.05), but no significant relationship was seen between other variables.Conclusions: According to our results and due to higher positive cases in 30-40 years-old women, more researches especially in pregnant women are suggested.
