  Background & Objective: Migraine is one of the chronic and Common Kinds of headache. Among important treatments which are advised for improvement of acute migraine attack, there are tryp tans and Ergot Alkaloids Because of side effects of Ergot Alkaloids Like nausea, vomiting, lack of appetite, Peripheral vessel contractions and induced headache and its limited consumption and patients age limitation, the patients face some difficulties using Ergot Alkaloid. On the other hand Tryp tans are Consumed as a monotherapeutic regimen but Ergot Alkaloids must be used with metoclopramide in order to prevent nausea and also they should be used in the acute phase of migraine so we decided to Compare the two groups of drugs so that if they have positive effectiveness in favor of Tryp tans, using them would be advised.

 Methods: The range of age for patients was 20- 40 years who suffered from classic and common migraine according to IHS criteria, were randomly placed in two groups. One group (36) was treated in the acute phase of disease by sumatryptan and the other (39) by a combination of 3 dihydroergotamine and naproxen and metoclopramide, and therapeutic effectiveness was studied by three Criteria of intensity, attack and frequency of attack. After the treatment, they were analyzed through chi square.

 Results: In terms of intensity, duration and frequency of the headache after the treatment, there was no significant difference between two groups and the results in both group were the same.

 Conclusion: As there were no significant statistical difference between the effect of two drugs on attack intensity, headache duration and frequency in patients of classic and common migraine, and because of the complications of Ergot Alkaloids like vomiting it should be consumed with metoclopramide and because of vessels contractions which may result in the organs gangrene and induced headache, and its maximum dose is 6 mg per week, sumatryptan is advised as the monotherapeutic.

  Background & Objectives : Bacterial vaginosis is a condition which is determined by changes in microbial ecosystem of vagina and is considered as a preventable risk factor for preterm delivery. This study was conducted to assess the effectiveness of bacterial vaginosis screening program in routine prenatal care and its effect on decreasing preterm labor.

  Methods: This clinical trial study was conducted on 474 pregnant women at gestational stage between 2007 and 2008. The participants were randomly divided into 2 groups: intervention group and control group. Screening was performed in intervention group with Amsel's criteria (3 of 4 needed for diagnosis). Positive cases were given clindamycin cream (2%) for one week. The outcome of the delivery was assessed in both groups afterward. Data were analyzed by SPSS11 software using descriptive statistics.

  Results: There was no significant difference between two groups regarding pregnancy rank, wanted and unwanted pregnancy, insufficient weight gain, mother vaccination and complication of pregnancy. Bacterial vaginosis was observed in 17 out of 216 (8%) in the intervention group and then treated. Prevalence of preterm delivery in the intervention and control groups were 3 (1.4%) and 12 (4.7%), respectively. The relative risk was protective (RR: 0.3, DR: 0.033, NNT: 30).

  Conclusion: Screening and treatment of bacterial vaginosis in pregnant women could significantly decrease the rate of preterm delivery.

Background & objectives: Metalloproteinases (MMPs) are one of the most important agents in cartilage damage in rheumatoid arthritis. Increase of these enzymes can change sensitivity to insulin. Therefore, in this study, the MMPs level, insulin sensitivity index and effective factor related to rheumatoid arthritis were evaluated in obese female with rheumatoid arthritis.
Methods: In the present study, 50 obese women with rheumatoid arthritis who were referred to the Sheikh Al-Reis clinic and Sina hospital in Tabriz and 50 healthy obese individuals were considered as case group and control group respectively. After determining the body weight, the levels of MMP-1, MMP-3, MMP-13, insulin, leptin, visfatin, resistin and glucose were measured using ELISA and Pars -Azmoon kits. One-way ANOVA method was used for statistical analysis of data. Pearson correlation test was used to evaluate the correlation between variables (p<0.05).
 
Results: in the present study, the mean level of MMP-1 (p=0.008), MMP-3 (p=0.015) and MMP-13 (p=0.001) in the case group was significantly higher than the control group. Also, Insulin- sensitivity index analysis didn’t show significant difference between the case group and the control group (p=0.21). In the case group, the level of leptin (p=0.000), resistin (p=0.000) and visfatin (p=0.024) was significantly increased compared to control group while insulin (p=0.231) and glucose (p=0.430) levels didn’t show significant increase.
Correlation results showed that there was a negative correlation between insulin and MMPs and a positive correlation with other parameters affecting insulin sensitivity.
Conclusion: our results showed, the matrix metalloproteinase level and the level of some factors affecting insulin sensitivity have increased in rheumatoid arthritis disease. Also, there was a significant positive correlation between the matrix metalloproteinase and some parameters affecting insulin sensitivity, including resistin and visfatin.

Background & objectives: Carbapenems are the main antibiotics for the treatment of infections caused by multidrug-resistant (MDR) Pseudomonas aeruginosa (P. aeruginosa). The aims of this study were to determine the prevalence of gene encoding outer membrane porin protein (OprD) in carbapenem-resistant P. aeruginosa strains as well as to assess the role of insertion sequence (IS) elements in the inactivation of OprD porin and the emergence of carbapenem resistance.
Methods: In this study, 103 clinical isolates of P. aeruginosa including 58, 42 and 23 strains resistant to imipenem, meropenem, and doripenem were used, respectively. The isolates were collected from patients referred to Ardabil hospitals. The presence of oprD gene and IS elements were investigated using polymerase chain reaction (PCR) and sequencing methods. P. aeruginosa PAO1 standard isolate was used as the positive control strain for oprD gene.
Results: The frequency of oprD gene among carbapenem-resistant P. aeruginosa strains isolated from Ardabil hospitals was 96.5%. Furthermore, IS elements were not observed in the investigated isolates.
Conclusion: Based on the results of this study, the presence of IS elements did not involve in the inactivation of outer membrane porin OprD and resistance to carbapenems among P. aeruginosa clinical strains in Ardabil. Therefore, an investigation of the role of other mutations in reducing the expression of oprD gene and increasing P. aeruginosa resistance to carbapenems is recommended.
