Abstract
Background and objectives: Irritable bowel syndrome (IBS) is one of the most common gastrointestinal diseases. It is a functional bowel disorder characterized by chronic abdominal pain and alternation of bowel habits with no structural abnormality. The prevalence of this disease was estimated 10-20 percent in the world. However, the cause of IBS is still unknown. Regarding to intestinal absorption disorder of nutrients, the malabsorption of vitamin may occur. The aim of this study is to evaluate serum levels of vitamins A and E in IBS patients.
Materials & Methods: This case - control study was done on 94 patients whom their IBS disease were confirmed by a gastroenterologist in Golestan province. The control group was selected from healthy people, who didn't show any signs of digestive problems in past two years. The age and sex were matched with the cases group. Using HPLC method, Fasting blood samples were collected .Followed by measurement of Serum levels of vitamins A and E.
Results: the meanserum levels of vitamin A and E in patients and control group were 57.0 ± 114.8μg / dl and23.8 ± 55.9 μg / dl, and 0.50 ± 0.24 mg / dl and 1.93 ± 1.86 mg / dl, respectively. (P <0.05). in men, the deficiency of Vitamin A and E, were7.70 and 7.10 percent and 6.76 and 3.7 in women. (P <0.05).In general, 1.1percent of IBS patients showed Vitamin A deficiency and 93.6 percent of them had vitamin E deficiency (P <0.05).
Conclusion: In this study, a significant decrease in vitamin E levels was observed in patients with IBS. Due to antioxidant activity of vitamin E, the deficiency of this Vitamin, can increase the oxidative factors leading to intestinal damages and it is expected to decrease the amount of vitamins, subsequently

Abstract
Background and Objective: Diabetes mellitus is one of complications that thalassemia major patients face with. Hence, blood glucose monitoring is of vital importance to these patients. Because of high level of fetal hemoglobin in these patients, the measurement of hemoglobin A1c is not reliable and should be displaced by fructosamine test.
Material and Methods: The current descriptive study was carried out on 33 beta-thalassemia major patients afflicted with diabetes mellitus (21 female and 12 male cases). Blood glucose level, fructosamine, hemoglobin A1c, serum ferritin and fetal hemoglobin were measured.
Results: Blood glucose levels are 204±103 mg/dL and 221±101 mg/dL (p=0.63) fetal hemoglobin levels are 9%±7% and 13%±9% (p=0.22) serum ferritin levels are 1744±1534 ng/mL and 3253±1773 ng/mL (p=0.96) in female and male patients, respectively. The level of fructosamine (42±124 mmol/L) and glycosylated hemoglobin (8.9%±1.8%) are correlated significantly (r=0.69, p<0.01). Both Hemoglobin A1c (r=0.75, p<0.01) and fructosamine (r=0.54, p<0/01) show a significant correlation with blood glucose level.
Conclusion: In diabetic thalassemia major patients with frequent blood transfusion, the level of fructosamine and glycosylated hemoglobin are related significantly, therefore they can be used alternatively.

Abstract
Background and Objective: Of the most common hypochromic microcytic anemia are iron deficiency anemia and minor thalassemia, which are common in Iran and their differential diagnosis is extremely important. The level of 25-hydroxy vitamin D is the indication of vitamin D blood status. The aim of this study was to compare serum levels of vitamin D in people with minor thalassemia and iron deficiency anemia with healthy subjects in order to investigate the relationship between vitamin D deficiency and iron absorption.
Material and Methods: In this case-control study, 24 patients with minor thalassemia, 20 patients with iron deficiency anemia and 24 healthy individuals participated. Groups were matched for age and sex. Testing of Vitamin D level by ELISA, ferritin by quantitative luminescence method and HbA2 by column chromatography was carried out.
Results: The number of individuals with low level of vitamin D in iron deficiency group is 15 (75%), in minor thalassemia group is 8 (33/3%) and in the control group 11 (45.8%).
Conclusion: In this study, the highest percentage of vitamin D deficiency is observed in cases with iron deficiency anemia. Because of association between vitamin D and anemia, iron and vitamin D supplementation is recommended to enrich the diet.

Abstract
Background and Objective: The patients with Post-Infectious Irritable bowel syndrome (PI-IBS), a subtype of irritable bowel syndrome, suffer from bacterial gastroenteritis. Since campylobacter Jejuni (CJ) is one of the most common agents in this syndrome, we aimed to evaluate the prevalence of Campylobacter Jejuni in patients with Irritable Bowel Disease.
Material and Methods: This case - control study was conducted on 160 patients divided into 2 equal groups of healthy and unhealthy. The presence of Anti- CJ antibody (IgG and IgA) was evaluated by ELISA and the comparison was performed by chi-square test.
Results: The mean age of case (31.51) and control (31.84) was not statistically different (P = 0.87). Titer of Anti- Campylobacter Jejuni antibody IgG was positive in 25% of patients and 18.8% of the healthy ones (p=0.02). IgA Seropositivity in patients was 7.5% but no one in control group was positive (p =0.01)
Conclusion: Seroprevalence of Cj in patients with IBS was higher significantly than that of control group. Thus, Cj can be known as one of the causes of Post-infection in patients with IBS in our region and it should be paid more attention in diagnostic assessment of these patients.

Abstract
Background and Objectives: Concentration low-density lipoprotein (LDL) is one of the strongest indicators of atherosclerosis and predicts the diagnosis of cardiovascular diseases. LDL measurement accuracy is very important. LDL can be measured directly, such as enzymatic and nephelometry methods or can be calculated using Friedewald's formula. Despite the development of enzymatic methods and LDL nephelometry still in most laboratories is calculated using Friedewald's formula. The aim of this study was an investigation of correlation coefficient between two methods of measuring LDL- cholesterol levels.
Methods: This descriptive cross-sectional study, performed on the 1141 patients. Cholesterol, triglycerides, HDL, LDL all patients assayed by enzymatic method. For patients with triglyceride levels of less than 400 mg/dl had LDL levels were calculated by Friedewald's formula. Normal levels of LDL/HDL ratio of less than 3.5 were considered.
Results: Of the 1141 patients participating in this study, 38.3 % men and 61.7 % women. The mean patient age was 46.3 ± 16.1 years. Mean serum cholesterol, triglycerides and HDL were 177.9 ± 41.1, 132.9 ± 73.2 and 45.8 ± 13.2 mg/dl, respectively. Average direct and calculated LDL concentration was 82.1 ± 23.1 and 105.5 ± 35.8, respectively. The direct measurement of LDL, LDL/HDL levels in 97.1% of cases was normal, while 85.1 % of the calculation of LDL were normal. Pearson correlation coefficients were obtained by two methods: 0.869 (p <0.001).
Conclusion: Despite the favorable correlation between two methods of measurements of LDL, the results of a calculation method is more than direct method. This can have a negative impact on the judgment of the treating physician.
Key words: LDL, Enzymatic Method, Friedewald's Formula.

Abstract
ABSTRACT
Background and Objective: Doxorubicin (DOX) is an effective anticancer drug. It has been shown that a short-term exercise performed prior to DOX-treatment has no effect on cardiotoxicity in young rats. In the present study, old and young rats were evaluated to determine the protective effects of pre-treatment with short-term exercise on DOX-induced oxidative damage in cardiac tissue.
Methods: Forty-eight male Wistar rats were randomly divided into two groups of young and old, and later divided into three sub-groups of young+DOX, young+training+DOX, young+training+salin, old+DOX, old+training+DOX and old+training+salin. The training protocol included treadmill running for 25-39 min/day at 15-17 m/min, 5 days/week for three weeks. All treatments were carried out 24h after the last exercise bout. The rats were sacrificed 48h
after DOX administration.
Results: Although DOX injection significantly affected the cardiac tissue of old rats compared to young rats, pretreatment with endurance training in DOX-treated rats caused an increase in Heat shock protein (3.02% vs. 23.36) and superoxide dismutase (30.12% vs. 31.12), and a decrease in malondialdehyde (10.92% vs. 19.60) in both old and young rats.
Conclusion: Although DOX-induced production of free radicals and cardiotoxicity in aged rats is more than that in young rats, the short-term aerobic exercise reduced the damaging effects of free radicals in the old rats more than in young ones. The concentration of antioxidant enzymes also increases with exercise in the old rats compared to young rats.

ABSTRACT
Background and Objective: Campylobacters are infectious zoonotic agents, and among the main bacterial causes of gastroenteritis in humans. Studies have shown that Campylobacter jejuni is of the main causes of infection among humans. Detection of these infectious agents in water resources is of great importance for maintaining the health of humans. Therefore, the aim of this study was molecular detection of C. jejuni strains in surface water samples collected from Rasht, Iran.
Methods: This cross-sectional descriptive study was performed on 45 surface water samples collected from the city of Rasht. After culture and isolation of bacteria, the molecular detection of C. jejuni was carried out using hipO-specific primers. Presence of cytolethal distending toxin (cdt) gene in positive samples was evaluated by polymerase chain reaction using cdtC-specific primers.
Results: Of 45 samples, seven (15.5%) were positive for C. jejuni contamination, five of which (71.4%) had the cdtC gene.
Conclusion: The prevalence of toxin-producing C. jejuni in surface waters of Rasht is notable. Therefore, it is recommended to take necessary measures for controlling the spread of this microorganism.
