Abstract
Background and Objectives: Gastric cancer is the most incident disease in Iran that leads to death. This study was designed to evaluate the oxidative and antioxidative status in patients with gastric cancer by detecting paraoxonase 1 and arylesterase activities together with the level of malondialdehyde. The purpose of the present investigation was determination of Paraoxonase /Arylesterase activity and malondialdehyde (MDA) levels in the serum of patients with Gastric cancer. Methods: In a case-control study, 20 subjects who diagnosed as gastric cancer individuals that referred to Ardabil Aras Clinic were selected from 2008 up to 2009. The case groups were matched with control group (30 subjects). Arylesterase and paraoxonase activities of paraoxonase-1 (PON-1), MDA levels and lipid profile were determined spectrophotometrically in serum of subjects. Results: Upon matching of case and control groups, paraoxonase and arylesterase activities in patients with gastric cancer showed to be significantly lower than healthy subjects (190 ± 68.95 IU/L vs 258 ± 68.59 IU/L, 30.5 ± 28.4 U/L vs 284.23 ± 163.2 U/L respectively, P ≤ 0.001). Standardized activities of paraoxonase and arylesterase of case group were lower than controls (P ≤ 0.001). MDA levels have revealed significant increasing in cases than controls. In present study, HDL cholesterol and triglyceride levels were found to decrease in patient sera too, but the levels of total cholesterol and LDL cholesterol didn’t show to be different between two groups. Conclusion: It was concluded that in patients with gastric cancer, oxidative stress was raised by attenuation of antioxidant system and oxidant levels rising.

Abstract
Background & Objectives: Stress in developing countries is an important problem in human health. Feelings of stress in humans result from interactions between persons and their environment. Stressor is an external stimulus or an event that provokes a stress response in an organism. Animal models enable preclinical testing of new treatments and therapies for physical symptoms of stress disorder. In the present study the effects of social stress on male mouse reproductive system were investigated. Methods: Sixty male mice were divided into 6 groups, including two non-stressed control groups (2 cages, 5 mice per cage), two mild-stressed groups (2 cages, 10 mice per cage), and two high-stressed groups (2 cages, 15 mice per cage). Three cages (one cage from each group) kept for one month and three cages kept for two months. After one and two months the mice were anaesthetized with ketamine and xylazine. Tissue samples of testes , epididymis and vas deferens for light microscopy were removed . Data analysis was performed using one-way ANOVA. P<0.05 was considered significant. Results: The results showed that there was no significant difference between mild and high-stresses groups in the diameter of seminiferous tubules, vas deferens, height of epithelial cells of epididymis and vas deferens. The diameter of epididymis in mild and high-stressed groups was significantly decreased as compared with that in non-stressed control groups (P<0.02, P<0.009). The diameter of vas deferens in mild-stressed groups was significantly decreased as compared with in non-stressed control groups (P<0.02). The height of epithelial cells of vas deferens in mild and high-stressed groups was significantly decreased as compared with that in non-stressed control groups (P<0.001, P<0.001). Conclusion: This study shows that crowding stress can decrease the diameter and height of epithelial cells of epididymis and vas deferens of male mice .

Abstract
Background & Objectives: Myocardial infarction is one of the most common causes of mortality throughout the world. Utilization of thrombolytic drugs at the first hours upon MI leads to decrease in the rate of mortality. Streptokinase (SK) is commonly used because of its cost and availability. The golden time for maximum effect of SK appeared to be first hours after MI. The drug efficiency diminishes after 3 hours and it will be ineffective after 12 hours. This study was aimed to investigate interval between onset of the clinical symptoms and streptokinase receiving in patients with acute myocardial infarctionadmitted for drug reception. Methods: This cross-sectional study was conducted in 150 patients with STEMI (ST elevation Myocardial Infarction ) who were attended to emergency room of Imam Khomeini hospital and fulfilled a questionnaire containing the data about age, sex, educational level, onset of symptoms, referring time to emergency room, SK utilization, past medical history of cardiac diseases, type and location of AMI, contraindications and side effects of SK. Results: In 111 men (74%) and 39 women (26%), the mean for interval between onset of symptoms and drug injection was 8 hour and 27 minutes ± 8 hour and 18 minutes .Only 41% of patients received streptokinase in less than 3 hours after chest pain. The main reasons for delaying in drug consumption were delayed decision to come to hospital in 61% of persons, long distance to hospital for 22% of individuals, delayed admission tor CCU for 13% of cases and delay in physician diagnosis for 0.043% of patients. To have a male sex and residency in city where the hospital was establilished were associated with less-delayed treatment start. However, the educational level, age and history of MI were not correlated with onset of treatment. Conclusions: Our results clearly show that the majority of patients receipt streptokinase more than 3 hours after chest pain. With considering the factors associated with delay to receive SK, teaching the patients with ischemic heart disease and giving information about golden time for thrombolytic therapy and its effect in prognosis as well as extending cardiac disease treatment centers in suburbs are recommended.

Abstract
Background & objectives: There are growing evidences about relationship between vitamin D metabolism and occurrence of diabetes mellitus. Vitamin D has a role in secretion and possibly the action of insulin and modulates lipolysis and might therefore contribute to the development of cardiovascular diseases. This study was aimed to evaluate whether serum vitamin D3 level in patients with diabetes is lower than that in non-diabetics and if its level has any relation to indices of metabolic syndrome. Methods: Sixty nine subjects were enrolled in this case-control study (23 diabetic patients with good control of blood sugar, 23 poor control diabetic patients and 23 healthy subjects as control group). Serum 25(OH) D3, Fasting Blood Sugar (FBS), (2 hour postprandial blood sugar) BS 2hpp, triglyceride (TG), total cholesterol, HDL and HbA1C were measured. We also measured blood pressure, body weight, height and abdomen circumference for individuals. The data were analyzed by Anova, Chi-square and Pearson correlation. Results: Serum levels of Vitamin D3 were significantly lower in diabetics compared to non diabetics. (36/5±16/6 v.s. 56/6±19/1 nmol/lit, p<0/001). There was no statistical difference between the group with good control diabetes and poor control diabetes. There was no significant correlation between low serum vitamin D and metabolic syndrome parameters. These findings suggest the need for ongoing evaluation of possible protective role of vitamin D3 supplement in the development of diabetes. Conclusions: Based on our results vitamin D deficiency is prominent in patients with diabetes. It appears the vitamin D level should be monitored in diabetic patients.

Abstract
Background & Objectives : Nowadays, coronary artery disease is the most common cause of death in developed countries and in the whole world. According to the WHO reports, it will be the main cause of death in 2020. Myocardial infarction is the most common diagnosis among hospitalized patients in industrialized countries. This disease causes more mortality and morbidity than others. Coronary artery bypass grafting surgery (CABGS) is one of the common treatments for ischemic heart disease but it may have some complications. In this study we wanted to evaluate the incidence of CABGS complications in Imam Khomeini Hospital of Ardabil in the first month after CABG. Methods: This study was a cross sectional analytic descriptive type and performed on all of the patients underwent CABGS in Imam Khomeini Hospital during 2011-2012. All of the data from patients (like demographic, past medical history, physical exam findings, paraclinical findings and CABGS complications) were inserted in special forms after gathering, and analyzed by SPSS v.16. Results: In this study, 211 patients were studied. About 145 (68.72%) of them were male and 66 (31.28%) were female. Seventy patient (33.17%) were more than 70 years old. About 33.22% of patients had a history of cigarette smoking and 9.95% were opioid abused. The 34.12% of patients had hypertension (HTN) history, 40.28% diabetes mellitus (DM), 17.06% history of hyperlipidemia and 63.98% had a history of the previous MI. Chest pain was the most common complication among the patients (93.36%). According to our study the prevalence rate of post CABGS complications were: bleeding after surgery 13.27%, postoperative myocardial infection 8.05%, neurological disorders 12.32%, renal complications 2.36%, respiratory symptoms 11.37% and 34.59% for cardiovascular complications. Also the total mortality was 5 (2.36%) persons. The data analysis showed that there was a significant relationship between sex with survival status, local infection and neurological disorders, and also there was a significant relationship between age with post CABGS survival, bleeding after surgery and renal complications. There was also a significant relationship between DM and post CABGS survival, local infections and respiratory complications and between HTN and local infections. Conclusion: According to the results of this study, the most common post CABGS complications were cardiovascular complications, especially arrhythmias.

Abstract
Background & objectives: KAI1 is a tumor suppressor gene and inhibitor of metastasis in a wide range of malignancies. While it is ubiquitously expressed in normal tissues, KAI1 expression subjects to the down regulation in tumors. The present research aims semi-quantitative evaluation of KAI1 mRNA expression in Iranian patients with colorectal cancer (CRC) and correlation between expression levels of KAI1 and stage oftumorigenesis, especially metastasis and invasion of CRC as well as pathologic factors of patients.
Methods: RT-PCR was done by specific primers for KAI1 and β-actin genes on the 80 tumor tissues and 14 normal tissues as fresh samples which obtained from 80 unrelated patients referred to Imam Khomeini Hospital.
Results: According the results, 51.2% and 48.8% of the sample were on and off for KAI1 gene expression, respectively. As a detail, 97.3% of samples in the stage 3 and 4 and 94.5% of metastatic phases samples showed no expression of this gene. Statistical analysis showed that there is a significant difference of the KAI1 expression between four groups of samples; normal, stage 1, 2 and 3 (p<0.05). Also a significant difference was observed between semi-quantitative KAI1 expression and degree of spread to regional lymph nodes (p=0.02) as well as semi-quantitative KAI1 expression and metastasis (p=0.000001).
Conclusion: A significant difference between semi-quantitative expression of KAI1 and degree of spread to regional lymph nodes (p=0.02) and metastasis (p=0.000001) was observed.

Abstract
Background & objectives: Chronic Obstructive Pulmonary Disease (COPD) is accompanied by systemic inflammations and is characterized by irreversible airflow limitations. Leptin is a cytokine with pre-inflammatory effect. However, there have been no studies on the effect of conjugated linoleic acid (CLA) on the serum leptin concentration in COPD patients. Therefore, the present study aimed to explore the effect of CLA on the serum leptin level, lung function and quality of life in COPD patients.
Methods: This interventional study was conducted on 90 COPD patients. The patients were randomly divided into two groups (supplement and placebo) with 45 patients per group. After obtaining written consent from the patients and recording their demographic characteristics, the spirometry was performed and COPD assessment test (CAT) score was calculated. Moreover, a fasting blood sample was collected from each of them in order to analyze their serum leptin concentration. After that, the patients in the supplement group were administered with 3.2 g/day of CLA for 6 weeks. The patients in another group received placebo. After the intervention, spirometry, CAT score calculation and blood sampling were repeated for all of the patients and the obtained results were analyzed.
Results: after the intervention, a significant decrease both in the serum leptin level and in CAT score as a quality life marker was observed in the supplement group (p<0.05). Moreover, the FEV1 levels as a lung function test, increased significantly in the supplement group after the intervention (p<0.05). Although, the difference between the two groups was not significant.
Conclusion: The use of CLA supplement can improve COPD patients’ quality of life through decreasing the serum level of leptin in their blood.

Abstract
Leishmaniasis is a parasitic infectious disease that accounts for approximately one million new cases annually. The treatment of this disease is complex and costly, particularly in developing countries. Numerous studies have been conducted on various vaccines utilizing live attenuated parasites, killed parasites, subunit antigens, recombinant vaccines, and DNA technology. However, an effective and widely applicable preventive vaccine for leishmaniasis has not yet been developed. Present study aimed to examine the progress in the development of leishmaniasis vaccines.
Articles for this study were selected from the PubMed, Web of Science and Scopus databases using relevant keywords, focusing on subject matter, scientific quality, and publication date, with an emphasis on more recent publications.
Research on the development of leishmaniasis vaccines indicates that several candidates, such as Leishmune, CaniLeish, and Leish-Tec, which are at various stages of clinical trials, may serve as suitable options for controlling and preventing leishmaniasis in dogs. The LeishChim vaccine, designed using immunoinformatics and molecular docking techniques, has shown promising efficacy results in mouse studies. Additionally, the mutant gene-centered LmCen-/- vaccine has completed Phase 1 clinical trials in humans.
Given the importance of developing a leishmaniasis vaccine, research in this area continues. Utilizing immunoinformatics and biological modeling studies can aid in the faster identification of effective vaccine candidates.
