Abstract
Background & Objectives: Chemotherapeutics induce side effects in patients with cancer . In animal models the intake of ω3 fatty acids during chemotherapy can increase the impact of chemotherapy drugs and reduce their side effects . This study was aimed to determine the fish oilintake on side effects of chemotherapy drugs in patients with gastric cancer. Methods: A double blind clinical trial study on 30 adult volunteer patients (15 experiments and 15 controls) with gastric cancer was conducted during chemotherapy in Ardabil, Iran, during 2010-2011 . Experimental and control groups were selected by randomized allocation. About 3 grams ω-3 fatty acid supplementation (1.8 g Eicosapentaenoic acid & 1.2 g Docosapentaenoic acid ) and placebo were given to experimental and control groups for 6 weeks, respectively . Then, the results of data were collected at the beginning, 4 and 6 weeks after intervention of ω3/placebo in both groups and analyzed by using descriptive statistics , Chi -Square , Independent sample t-test and Cochran,s Q test. Results: The results of this study showed that there were significant differences of nausea in both group of patients at the end of 6 weeks (p<0.05). A bdominal cramp and nausea significant ly decreased in experimental group during the study (p<0.05). Hair loss , vomiting and diarrhea were reduced in experimental group during the study, but these differences were not statistically significant . There were no significant differences in vomiting , diarrhea and hair loss between two groups at the end of intervention. Conclusion: The present study showed that the intakes of fish oil strongly reduce side effects of chemotherapy drugs such as nausea and abdominal cramp.

Abstract
Adjuvants are chemicals, microbial components, or mammalian proteins that enhance the immune response to vaccine antigens. Reducing vaccine-related adverse effects and inducing specific types of immunity has led to the development of numerous new adjuvants. Adjuvants in experimental and commercial vaccines include aluminum salts (alum), oil emulsions, saponins, immune-stimulating complexes (ISCOMs), liposomes, microparticles, nonionic block copolymers, derivatized polysaccharides, cytokines, and a wide variety of bacterial derivatives. The mechanisms of action of these diverse compounds are different. Factors influencing the selection of an adjuvant include animal species, specific pathogen, vaccine antigen, route of immunization, and type of immunity needed. In this paper we review the current adjuvant types, structure and mechanism of action and their application in the design and production of animal and human vaccines to provide a source for students and researchers in related fields .

Abstract
Background and Objectives : Familial Mediterranean Fever, an autosomal recessive disorder, is the most common and well known periodical fevers syndrome. Disease is mainly prevalent among non-Ashkenazi Jews, Arabs, Turks and Armenia. According to the geographical location of North-West of Iran, neighboring with two high risk FMF population (Turkey and Armenia), the prevalence of FMF in this region of Iran is not unlikely. The aim of this study was to estimate the carriers rate of FMF common mutations in healthy control people. Results can be potentially useful to estimate prevalence of disease. Methods : Randomly 200 samples from healthy people [non-FMF] from North-West of Iran selected. After taking consent, DNA was extracted from blood samples of these groups. Then mutations were evaluated using ARMS-PCR and RFLP-PCR techniques. Results : from 400 studied alleles, 44 and 7 mutant alleles were found for E148Q and V726A respectively. For 2 other mutations, no mutant alleles were found. The total allelic frequency for these four common mutations was 0.132. The carriers rate was 23.4%. Conclusion : This study showed that E148Q has high mutation frequency relative to other mutations in North-West of Iran.

Abstract
Background & Objective: It's been considered that midbrain region namely rostral ventromedial medulla (RVM) is the coring point of modulation of pain. The periaqueductal gray (PAG) matter has been documented to act as antinociceptive along with RVM. However, there are evidences demonstrating that RVM get a few connections from the cuneiformsnucleus (CnF) which might indicate CnF does have the same mechanism as PAG. Thus in this study, we tried to explore the antinociception effects of CnF and GABAA circuits. Methods: Rats were anesthetized with Thiopental drug. Using the stereotaxic apparatus and Paxinos atlas, the point representing for CnF location over the scalp has been designated. One week after the surgery, rats were fully prepared for tests. Animals were put in three groups. First for control group, 0.5 µl of normal saline was injected into the CnF. Later, a few nanograms of bicucculline (as a GABAA antagonist) were administered into the CnF, dose dependently. Results: From the results, it has been shown that CnF has a role in antinociception effect since the injection of bicucculline increased tail flick latency (TFL) and even further increased TFL when administered dose dependently (with high doses). Conclusion: According to results of current study, CnF has a significant role in pain modulation and circuits of GABAergic system also plays a key role on its antinociception effect.

Abstract
Background & Objectives: Numerous studies have been conducted to assess the effects of acute resistance exercises on the structure and the function of heart, but little works done on effects of chronic resistance exercises. So, the objective of current study was to investigate the long term effect of regular exercises on cardiac function and oxidative stress. Methods: Forty male Wistar rats in the weight range of 250- 300 g were used in this study. They were divided in 2 following groups: The 3 months exercises test group and control group which remained without exercises. Regular resistive exercise was carried out according to the model proposed by Tamaki et al. Test group rats exercised for three months. Finally the hearts of 10 rats in each group were taken for homogenization, oxidative stress measurement and the other ten were examined for heart function. Malondialdhyde as an index of oxidative stress and superoxide dismutase, glutathione peroxides and catalase as an indicator of antioxidant capacity with special kits were specifically measured. Results: Regular resistive exercise didn't significantly affect the rats' weight, but heart weight in exercise group showed a significant increase (p<0.05). There was a significant decrease in heart rate in exercise group (p<0.05). Left ventricle contraction strength and coronary flow had a significant increase in exercise group in comparison with control group (p<0.05). There was not any significant difference in Malondialdhyde and antioxidant enzymes activity. Conclusion: This study showed that, heart efficiency had a significant improvement under effect of regular resistive exercise. Meanwhile, regular resistive exercise didn’t have any significant effect on oxidative stress and heart antioxidant defense capacity.

Abstract
Background & Objectives: Ethambutol is one of the four main drugs in treatment of tuberculosis. The most common mutation associated with this drug resistance usually occurs in codon 306 of embB. The aim of this study was to detect ethambutol resistance using Allele-Specific PCR and Spoligotyping in various subtypes of Mycobacterium tuberculosis. Methods : 140 sputum specimens were collected from suspected TB patients. They were digested and decontaminated using Pettrof method before culturing them on LJ medium. Drug susceptibility testing was performed on 106 culture positive specimens using proportional method. DNA was extracted from the isolated organisms and subsequently subjected to Allele-Specific PCR to detect any mutationin embB306. Spoligotyping was then used to determine the subtypes. Results: Out of 106 cultures positive samples, 36 samples (33.9%) showed resistance to ethambutol using proportional method. Allele-Specific PCR assay identified 93 as sensitive and 13 (27.6%) as resistant strains. The results of PCR were in agreement with result of proportional method. The PCR method revealed that 61.5% of mutation occurred in the first and 38.5% in third nucleotides. Spoligotyping differentiated Mycobacterium tuberculosis strains into Beijing (10 9.4%), Bovis (2 1.8%), CAS (24 22.6%), EAI (1 0.9%), Haarlem (27 25.4%), LAM (5 4.7%), Manu (5 4.7%), T (27 25.4%) and U( 2 1,8%) families. The high frequency of mutation in embB gene was belonged to Haarlem, CAS and T subfamilies. Conclusion: Based on results current study, mutations in the genes other than embB might have occurred in the resistant strains that gave negative result in Allele-Specific PCR assay. Therefore other mechanisms of resistance to this antibiotic should be investigated.

Abstract
Background & Objectives : Intense training increases the production of free radicals and causes inflammatory response in athletes. Strengthen and improving athlete’s immune system may reduce the harmful effects of intense physical activity. The aim of this study was to investigate supplementary consumption of coenzyme Q10 on serum concentration of tumor necrosis factor-alpha (TNF-α) during the maximal activity. Methods : Twelve healthy active males (age 21.75 ± 0.64 yr, BMI 23.7±0.94 kg/m2) performed 30-min exercise at 80% to 85% HRmax. Subjects 120 minutes pre-exercise received either of the following regimens: Coenzyme Q10 (2 mg per kg body weight) or placebo (food color). Blood samples were obtained prior to supplement consumption and immediately after exercise, then groups were reversed after 4 days. The data were analyzed using paired and independent t-test. The statistical significance was set at p<0.05. Results: TNF-α serum level increased in both supplementation and placebo group (4.2% and 5.12% respectively) and the difference between two groups was insignificant. Conclusion : The results of this study indicated that after maximal activity increasing of TNF-α serum level was slower in the supplement group in comparison with placebo group but Q10 consumption did not caused a significant difference between two group (p=0.8).

Abstract
Background & Objectives: Matrix Metalloproteinases (MMPs), a member of photolytic enzyme family, degrade the extra cellular matrix. MMPs have very important roles in physiological and pathological processes. It has been reported that MMPs concentration increase in malignancies such as stomach, breast, colon, lung, head and neck cancers . Infectionwith Helicobacter pylori is risk factor for gastric cancer and may increase the serum level of MMP-9. The aim of this study was to measure the concentration of MMP-9 in sera of patients infected with H. pylori. Methods: In a descriptive-experimental study, apparent healthy individuals who were refereed for stool and blood tests were randomly selected and their stools and sera samples were collected. A questionnaire containing age, sex, smoking and special diseases in family and type of their diseases was filled for every volunteer. The sera collected immediately after blood sampling and stored in -70oC until used. The concentration of MMP-9 was assessed using ELISA. Stool samples were used for detection of H. pylori antigen. Results: H. pylori positive, negative and equivocal volunteers were 52.38%, 29.76% and 17.85%, respectively. Differences between MMP-9 concentration and H. pylori negative and positive groups were not significant (p=0.25). A significant increase in MMP-9 concentration was found in sera from drivers in compare with housewives. Conclusion: Although there was an increase in serum concentration of MMP-9 in H. pylori infected person, differences between H. pylori negative and positive groups were not significant. The raised concentration of MMP-9 in drivers may arise from difference in their health condition in compare with the housewives. This study suggests that MMP-9 level in serum may increase before initiation of gastric cancer in H. pylori infected individuals.

Abstract
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.

Abstract
Background & Objectives: Several studies have shown that Glucocorticoids affect learning and memory processes by influences on limbic structures such as amygdala. The amygdala is an important region for memory formation. Considering the existence of the muscarinic acetylcholine receptors in the basolateral amygdala (BLA), the aim of the present study was to investigate the effect of intra-BLA microinjection of pilocarpine on the effect of dexamethasone on memory retrieval . Methods: As a model of learning, using a step-through apparatus , inhibitory avoidance was used for assessment of long-term memory in 80 adult male Wistar rats . All animals were bilaterally implanted with cannulas into the BLA and were trained and tested (with 24 h interval) 7 days after surgery. Memory retrieval was evaluated by recording of the step-through latencies and the time spent in dark chamber of apparatus in the testing day. Results: Pre-test subcutaneous (s.c) administration of dexamethasone (2 mg/kg) impaired memory retrieval in animals when trained 24 h in advance. Co-pretest microinjection of different doses of pilocarpine (1 , 2 μg/rat, intra-BLA ), a muscarinic acetylcholine receptor agonist, with the dexamethasone (2 mg/kg, s.c) caused enhancement of memory retrieval. Conclusion: Results of this research indicate that impairment effect of dexamethasone on memory processes may be mediates by decrease of mechanisms of BLA muscarinic cholinergic.

Abstract
Background & Objectives: I ntra-hippocampal adminestration of origanum (ORG) improves spatial learning of rats. T he aim of the present study was to investigate the possible mechanism for origanum extract on spatial learning and memory in the hippocampus. Methods : In this study 42 adult male Wistar rats were used . Animals were cannulated bilaterally in the posterior laterl of hippocampus. After the recovery period, the spatial learning and memory were assessed using Morris Water Maze (MWM). Saline, ORG (0.03μg/site) glutamate receptor antagonist MK801 (0.08, 0.2 and 0.4 μmol/site) and co-injected of MK + ORG was injected into the posterior lateral of hippocampus 20 minutes before the training and retrival sesions (for 5 consecutive days) (n=7). Results: The results showed that the intra-hippocampal injection of MK 801 significantly blocked the decreased distance and time of reaching (due to ORG injection) to find hidden platform of MWM (p<0.05). On the retrival tests, the average of time spent in the target area is reduced in the co-injected of MK801 + ORG group. Conclusion: The intra-hippocampal injection of aqueous extract oforiganum may improve working memory in rats through glutamate-dependent NMDA receptors.

Abstract
Background & Objectives: Polycystic ovary syndrome (PCOS) is one of the major endocrine disorders among females. PCOS is associated with development of type 2 diabetes and cardiovascular disease. The objectives of this study were to determine the effects of omega-3 fatty acids on glycemic status and high sensitive C-reactive protein in women with PCOS. Methods: This double-blind randomized controlled clinical trial was conducted on 61 PCOS patients. Subjects in ω-3 fatty acids (n=30) and placebo (n=31) groups take 4 ω-3 fatty acids capsules (each one contained 180 mg eicosapentaenoic acid and 120 mg docosahexanoic acid) or placebo daily for 8 weeks. Anthropometric and biochemical measurments and food intakes were assessed at the beginning and at the end of the study. Results: ω-3 fatty acid supplementation caused significant decrease in serum levels of glucose, insulin (p < 0.001 for both) and insulin resistance (p = 0.002) at the end of the study in comparision with baseline values. This was also statistically significant compared to the placebo group (p < 0.001, p = 0.002 and p = 0.001, respectively). No statistically significant differences in serum levels of high sensitive C-reactive protein were obsereved in any of groups at the end of the study (p > 0.05). Conclusion: ω-3 fatty acid supplementation had some beneficial effects on glycemic status of PCOS patients and may be useful in prevention and control of metabolic conmplication of this syndrome.

Abstract
Background & Objectives: Over 150 different surgical techniques for treatment of anterior shoulder instability has been suggested that there is no consensus in the orthopedics. This study seeks to compare treatment outcomes of arthroscopic Bankart lesion repair methods with Bristow - Latarjet open surgical technique in patients with anterior shoulder instability. Methods: In this cross-sectional study all patients with recurrent shoulder dislocation from 2009-2011 was divided into two groups, arthroscopic Bankart treatment (28 cases) and open Bristow - Latarjet (26 cases) that all were treated by one orthopedic surgeon. Patients were visited in 2,4,6,8 weeks also in the third and sixth month post-op .The visual analog scale (VAS) for patient satisfaction and Walsch-duplay and Rowe score for functional outcomes of treatment were used in six months follow up. These three criteria were analyzed again after recalling the patients. Results: Mean age of 54 patients was 29.46±9.16 years and mean follow-up duration was 23.28 ± 6.2 months. Scores of patients in both groups were not statistically different after analyzing the functional outcomes of treatment by Walsch-duplay and Rowe score after six months and final follow-up. Scores of patients by Walsch-duplay measurement in arthroscopic Bankart and Bristow-Latarjet groups were 98.03±4.37 and 97.88±4.51 respectively and by Rowe index were 97.32±5.52 vs. 97.88±4.51at final follow-up. No recurrence was observed in both groups in final follow up. Patient satisfaction in Bankart and operation groups were 9.4 ±0.68 and 9.47±0.58 (p= 0.69). Conclusion: In anterior shoulder instability, minimally invasive Arthroscopic Bankart procedures almost equal to open Bristow-Latarjet method with regards to shoulder stability, recurrence rate, and range of motion.

Abstract
Background & Objectives: Haemophilus influenzae is a Gram-negative bacterium that is part of the normal nasopharyngeal flora of most humans. H. influenzae strains were defined in two categories: encapsulated (typeable) and non-capsulated (nontypeable) strains. Outer membrane protein P6 is a highly conserved and stable protein in the outer membrane of both encapsulated and non-capsulated strains of H. influenzae. As an immunogen, P6 protein is a potential candidate vaccine against H. influenzae strains. The aim of this study was to produce recombinant protein P6 as a carrier protein for production of conjugate vaccines. Methods: The sequence (324 bp) coding P647-153 protein of H. influenzae was successfully cloned in pJET1.2 and subsequently in pET28a (+). Expression of the recombinant protein was induced with 1mM IPTG. Recombinant P647-153 was purified through dissolving inclusions in 8M urea buffer, absorbing to Ni-NTA resins, washing by buffers with decreasing urea concentration and finally eluted in Imidazole solution. Imidazole was removed by dialysis against PBS (pH 7.4). The recombinant p6 47-153 was confirmed by western blot analysis using rabbit anti H. influenzae polyclonal antiserum. Results: The recombinant P647-153 was successfully expressed in E. coli BL21 (DE3) and purified (4 mg /lit of broth culture). The immunoblotting showed that recombinant P647-153 conserved its native antigenic structure. Conclusion: Western blot results, along with that of sequencing, confirmed accurate production of recombinant P647-153 and partially retention of its conformational epitopes.

Abstract
Background & Objectives: Plasma lipids during pregnancy clearly increase, therefore, normal pregnancy is considered as a hyperlipidemia state. Prior studies suggest that coronary artery diseases connected with parity, but no studies have examined the relationship between parity and lipid levels in Iran. In the current study we investigated the relation between parity and lipid levels in maternal plasma in 13-23 weeks pregnant women. Methods: This study was done on 700 pregnant women with 18-40 years old at their 13-23 weeks gestation. Gestational age was calculated by LMP and ultrasound in early pregnancy. After obtaining informed consent from patients without exclusion criteria of the study, TC, TG, HDL-C and LDL-C was requested for them. Finally, the samples of study divided three groups according to the number of parity: nuliparous , multiparous , Grand multiparous . Data were analysed by SPSS-16 software using ANOVA and partial correlation statistical test. Results: With the exception of TG that showed significance difference in mean (p=0.008), the means of LDL-C (p= 0.37), HDL-C (p= 0.09) and TC (p=0.15) were not statistically significant among the 3 studied groups. Partial correlation test indicated statistically significant relationship between HDL-C with parity. Conclusion: The results of this study indicate decreased HDL-C levels with increasing number of pregnancies. Thus offering the program education and adequate family planning services to women in reproductive age are strongly advised.
