Abstract
Introduction: The relation between Helicobacter pylori with iron deficiency is being studied in recent years. The aim of this study is finding the relation between Helicobacter pylori with the rate of hemoglobin and serum ferritin.
Material and Methods: This study is an observational study and a cross-sectional type which is done analytical-descriptive against 262 patients suffering from anemia and for each patient the amounts of Hemoglobin, MCV, serum ferritine and Helicobacter IgG titre is calculated and then the relation between these amounts and Helicobacter is evaluated.
Results: In 147 patients (56%), Helicobacter IgG antibody was negative. In 78 cases (29.8%) the serum ferritin was less than 120 µgr/dlit. Using statistical analysis (Logistic regression) revealed that there was a statistical relation between the amount of ferrittin and the chance of strickened with Helicobacter in individuals whom their ferrittin rate was less than 12, 1.93% of patients whom their ferrittin is more than 12 and the enhance is significant. By the way it was cleared that there is not any significant statistical relation between MCV reduction and the chance of being strickened with Helicobacter.
Conclusion: Serum ferrittine rate in patients with Helicobacter pilory infection reduced and this reduce was significance. Previous studies in other countries indicated to this issue.

Abstract
Introduction: Regarding the fact that dissanitation in swimming pools can cause a lot of diseases such as Dermatophytosis in swimmers, this study is done with the aim of determination of Dermatophytic infections in covered public swiming pools of Qom city during 2004. Materials and Methods: In this descriptive study 480 samples were taken from six public swimming pools. Samples were carried to the laboratory where they were passed through milipore filters. Filters then were trasfered to mycosel agar medium and incubated for three weeks at 25 Co. Data was analyzed using fisher test. Results: Among 480 samples, eleven Dermatophytes (8/8 percent) were isolated and indentified as follow: Trichophyton Mentagrophytes (2/4%), Trichophyton Tonsuranse (1/6%), Trichophyton Equinum (1/6%), Trichophyton Verrucosum (0/8%) Trichophyton Rubrum (0/8%), Trichophyton Schoenlinii (0/8%) and Epidermophyton Floccosum(0/8%). There was a significant relationship between prevalence of Dermatophytes and disregarding of personal hygiene standards (p=0/0001) and no significant relationship between residual Chlorine of swimming pools and prevalence of Dermatophytes. Conclusion: Because the majority of isolated Dermatophytes were anthropophilic and had been transferred from swimmers to the swimming pools it is necessary to care personal hygiene standards and provide good sanitation conditions in water and environment of the swimming pools.

Abstract
Background: Tension headaches are the most basic reasons for referring to physicians throughout the world. Iron anemia, on the other hand, is the most common type of anemia among women who are in productive age in the world. This study was done to investigate the relationship between vascular headaches and iron anemia and to see the effect of iron tablets administration on the treatment of these headaches in women who are in productive age. Materials and Methods: In this quasi-control study, 50 women in reproductive age who had iron anemia and vascular headaches, referring to the neurologic clinic of Vali-asr Hospital in Arak, were selected and treated with ferrous sulfate tablets for three months. For verifying the treatment, patients' hemoglobin was monitored after one month, and in case of any significant increases in this value, the patients discontinued participating in the study. The number of headache attacks and the number of analgesics used before, through and three months after beginning the administration of ferrous sulfate were noted for all of the patients. Results: The mean number of the headache attacks one month before treatment, during the treatment and three month after the treatment were 19.6±28 , 14.2±11.2 , 13.3±11.8, respectively (p=0.0001) . In addition, the mean number of used analgesics before the treatment, through the treatment and three month after the treatment were 30.1±14.1, 14.3±11.2, 13.1±16.1, respectively (p=0.0001). Conclusion: It seems that using iron tablets can be useful in treatment of vascular headaches.

Abstract
Background: The aim of this study is to assess antioxidative and pro-oxidative efficacy of ascorbate on serum albumin during iron-induced oxidative stress. Materials and Methods: In this experimental study, albumin was placed in the oxidative system containing iron ions and different concentrations of ascorbate. To monitor albumin degradation, sodium dodecyl sulfate polyacrylamide gel electrophoresis was performed according to Laemmli procedure. Oxidative modification of albumin was demonstrated using a method for determination of carbonyl groups by 2,4-dinitrophenylhydrazine. Results: By applying the carbonyl assay, ascorbate showed a dual effect: initial pro-oxidative effect on albumin changed to an antioxidant one in a dose-dependent manner. Our findings showed prooxidant effects for ascorbate in low concentrations (0-100 µM) and antioxidant effects in higher concentrations (100-300 µM). Also, electrophoretic pattern of plasma proteins showed significant protein aggregations in the range of 35 to 45 kDa of MW and protein degradations in the range of 115 to 180 kDa. Conclusion: Ascorbate can produce reactive oxygen species and can also inhibit the production of these oxidants in the presence of iron ions as well. These findings may be directly applicable to oxidative states during the administration of ascorbate and may be important in preventing oxidative modifications of proteins in blood circulation and other biological fluids.

Abstract
Background: The presence of nitrate in drinking water causes various health and environmental problems. The aim of this study was to evaluate the efficacy of nitrate reduction by Fe/H2O2 process and adsorption on activated carbon. Materials and Methods: This experimental study investigated nitrate oxidation by advanced oxidation process of Fe°/FeІІ/FeШ/H2O2 at pH 2-10, nitrate concentrations of 50-300 mg/L. After adjusting the pH, 0.5, 1, 2, 5, and 10 g/L values of GAC, PAC, H2O2/GAC, and Fe/H2O2/GAC together with H2O2 at retention times of 15, 30, 45, 60, and 90 minutes, respectively, were added and mixed. Results: At retention time of 10 minutes and 0.5 mL H2O2 and 1 g/L from Fe°, FeІІ, and FeІІІ, the removal efficacy was 88.5, 84 and 78%, respectively. At 50 mg/L nitrate and 0.5, 1, and 10 mg/L GAC concentrations, the removal efficacy was 56.5, 93.6, and 82.6%, respectively. The nitrate removal efficiency at pH=4 was approximately 50%, whereas at pH=3 with 30% efficacy, it increased to 80%. Conclusion: Modified Fe/H2O2 process with iron nano-particles and activated carbon adsorption can effectively reduce nitrate under optimal conditions. The use of activated carbon at a concentration of 1 g/L increased the removal efficiency of nitrate to 90%.

Abstract
Background and Aim: Prolonged ischemia in organs with high metabolic rates such as brain and heart is associated with deleterious effects. Therefore, nutritive distribution through angiogenesis after ischemia is necessary for repairing damaged region of tissue. In this study, the effects of iron oxide nanoparticles and magnetic field on angiogenesis after ischemia reperfusion (IR) in rat model have been investigated.
Materials and Methods: In this experimental study, fifty male rats aged between 6 -7 weeks at the 220-250gr weight were purchased from Tehran University. Animals were categorized in 5 groups including sham (ischemia reperfusion model), control, iron oxide nanoparticles-treated, magnetic field-exposed, and combination therapy with iron oxide nanoparticles and magnetic field-exposed groups. Angiogenesis was evaluated in hippocampus of 5 groups after 4 days by H&E staining method. The expression of Vegfa gene was studied in 5 groups by Q-RT- PCR.
Findings: Iron oxide nanoparticles as well as the magnetic field induced angiogenesis during 4 days in animals after IR (p<0.05), but their combination therapy did not show any significant difference compared to sham group during 4 days. Upregulation of Vegfa gene was observed in iron oxide nanoparticles treated group and the magnetic field exposed group significantly (p<0.05) relative to ischemia reperfusion (IR) model. But overexpression of Vegfa gene in combination therapy group was not significant relative to ischemia reperfusion (IR) group.
Conclusion: It seems that iron oxide nanoparticles and magnetic field can separately be two effective methods for angiogenesis after ischemia reperfusion (IR).

Abstract
Background and Aim Thyroid diseases are among the most common endocrine disorders. Animal and human experiences indicate that iron deficiency disrupts thyroid metabolism. On the other hand, iron therapy can improve thyroid function and even decrease the dose of levothyroxine.
Methods and Materials In this randomized clinical trial, we selected 94 women with hypothyroidism by simple random sampling method and divided them into two equal groups by simple block sampling. At the beginning of the study, we measured and recorded T4, TSH, T3, and iron profiles (Serum iron, total iron-binding capacity, ferritin, Hemoglobin) in all patients. Then, the patients in the intervention group were treated with levothyroxine plus 100 mg oral iron daily for 8 weeks, and the patients in the control group were treated with levothyroxine only. After two months, we measured their T4, TSH, T3 levels and iron profiles in both groups again.
Ethical Considerations The Research Ethics Committee of Arak University of Medical Sciences approved this study (Research Ethics Code: 1396154). Also, the study has been registered at the Iranian Registry of Clinical Trials (Code: IRCT 20151114025031).
Results After 2 months, the TSH Mean±SD serum levels were found as 2.2±1.0 mIU/L and 2.9±1.1 mIU/L for the intervention and control group, respectively (P=0.04). Also, the serum Mean±SD level of T4 and T3 were found as 9.3±1.48 mcg/dL vs. 8.2±0.9 mcg/dL (P=0.01), and 1.6±0.3 ng/mL vs. 1.1±0.3 ng/mL (P=0.01), for two different groups, respectively.
Conclusion Concurrent administration of iron supplementation with the usual dose of levothyroxine in patients with hypothyroidism decreases THS level and improves laboratory parameters and response to treatment.
