Background and Objective: Open fractures mostly appear in leg (24%), and often accompany with soft tissue defects that predispose the limb for amputation. One of the best ways for limb salvage is to support both bone and soft tissue by the means of soft tissue reconstructing surgeries. The aim of this study was to evaluate the outcomes of soft tissue reconstruction surgeries in legs open fractures. Materials and Methods: This descriptive study was performed on 59 patients with leg open fractures and soft tissue reconstruction surgery at Shahid Kamyab hospital in Mashhad, North-East of Iran during 2004-05. Individual characteristic, clinical and physical examination, and outcome of the surgery were gathered in a questionnaire and analyzed by descriptive and Chi-Square test. Results: Eight patients excluded and finally the study was done of 51 patients. Out of 51 patients 84.3% were male with mean age of 30 years. Leg open fractures in 76.5% of patients was IIIB type. Surgery was successful in 76.5% of patients. Delayed ::::union:::: occurred in 56.9% and osteomyelitis in 33.13% of patients. There was a correlation between the time of soft tissue reconstruction and ::::union::::, deep infection and osteomyelitis (P<0.05). Conclusion: This study showed that high frequency of deep infection, osteomyelitis and delayed ::::union:::: due to leg open fractures with lack of soft tissue.

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.

Background and Objective: Menopausal symptoms influence mental, physical and emotional health, as well as social performance and family relationships. Due to the undesirable side effects of alternated hormone-therapy, tendency toward alternative treatments in relieving these symptoms have been increased, and the use of herbs like phytoestrogens seem preferable. This study was conducted to determine the effect of red clover Isoflavones extract on menopausal symptoms. Materials and Methods: This clinical randomized, triple-blind trial was conducted on 72 menopausal women who referred to Navab Safavi health care center, Isfahan, Iran during Oct-Apr 2011. After two weeks of monitoring and determination of the baseline symptoms score including hot flushes and sweating, paresthesia, insomnia, nervousness, depression, vertigo, weakness and fatigue, arthralgia and myalgia, headache, palpitation and formication, the women were randomly divided into two groups of 36 subjects: placebo and intervention (taking 45 mg of red clover Isoflavones extract capsules). The subjects were given one capsule daily for eight weeks and menopausal symptoms were recorded weekly. Data were analyzed using SPSS-18, independent t-test, ANOVA, chi-square and Mann–Whitney tests. Results: 55 women completed the study: 27 subjects in the placebo and 28 in the intervention group. The mean age of subjects in placebo and intervention group was 53.923.21 and 52.963.07 years, respectively. The mean age of menopause in the placebo and intervention groups was 51.382.63 and 50.051.17 years, respectively. The mean elapsed time since menopause was determined as 2.691.47 years in placebo and 2.661.65 years in intervention group. The average score of menopausal symptoms at the end of the 10th week was 13.877.22 and 16.4411.59 in intervention and placebo groups, this reduction was significant (P<0.05). Conclusion: This study showed that consumption of capsules containing red clover Isoflavones extract for 8 weeks, reduces menopausal symptoms in postmenopausal women.

Background and Objective: Listeria monocytogenes is a gram-positive and foodborne pathogen that is psychrophilic and has the ability to tolerate a high percentage of salt by more than 10%. This bacterium grows in many food products that have a long shelf life. This study was performed to evaluate the expression of genes hly and inlA of Listeria monocytogenes bacteria in the viable but non-culturable (VBNC) condition in temperatures of 4 degrees Celsius.
Methods: In this descriptive laboratory study, bacteria in 10⁶ counts in mid log phase were inoculated into BHI Agar rich medium and It was investigated and stored at refrigerated temperature (4 degrees Celsius) until the cultivate was lost. At the end of the 16S rRNA gene, the hly and inlA genes were studied as pathogenic genes of this bacterium. The expression of these genes before and after entering to VBNC state was performed to compare their expression.
Results: Listeria bacteria lost its cultivation ability after 5 months of storage at a refrigerated temperature. The results of the gene expression analysis showed that at the end of the period, the bacterium entered "Viable But non-Culturable" form; also the hly and inlA pathogenic genes were not expressed in riched medium. By adding blood to the rich culture medium of this bacterium, the hemolysin O pathogen gene was re-illuminated.
Conclusion: The results of this study show that the possibility of bacterial entry into VBNC mode occurs at the refrigerator condition, and the expression of its pathogenic genes is affected. Blood and its agents can act as an agent for the induction and clarification of the hly gene. Therefore, it is necessary to review the microbial quality control of fishery products.
