Introduction: Although more  than  two  decades  is  passed  from  the  discovery  of  H.pylori  and  its  role  in  pathogenesis  of  upper  GI  disease, a  uniform  protocol  for  H.pylori  treatment  is  not  administrated  yet.  This  research  is  conducted  to  evaluate  knowledge,  attitude  and  practice  of  physicians  about  H.pylori  disease  and  treatment  and  its  changes  after  reading  a  review  article.
Materials  and  Methods: This  is  an  interventional  study. First we  prepared  a  compact, review  article  for  the  purpose  of  teaching  H.pylori  pathophysiology, diagnosis  and  treatment.  Then  thirty  questions  was  brought  out  to  evaluate  knowledge, attitude  and  practice  of  the  physicians  about  H.pilory   diagnosis  and  treatment. After  the  first  evaluations  we  gave  our  article  to  the  physicians  to  study.  One  month  later  we  repeated  the  evaluation  with  the  same  questionnaire.  Data  was  analyzed  by  SPSS  software.
Results:  304  physicians  participated  in  this  study.  The  mean  evaluated  knowledge  was  49.64-58.75  with  95%  confidence  interval;  which  after  education  increased  to 57.94-74.14 (p<0.05). Mean  level  of  attitude  and  practice  was  53.01-71.67  with  95%  confidence  interval. After  studying  it  increased  to  61.54-80.83 (p<0.05).
Conclusion: The  first  step  of  the  study  showed  that  test  and  treat  is  the  protocol  of  choice  for  many  physicians.  After primary  evaluation  and  introducing  the  compact  article  there  was  a  noticeable  change.

Introduction: Hepatitis B is a disseminated liver inflammation from HBV, that causes diseases and a large number of deaths. Regarding the fact that some of the vaccinated people are non responder (NR), evaluation of immunity in vaccinated ones and identification of NR especially in high risk group is necessary.
Materials and Methods: In this descriptive study blood samples of all medical students of Borujerd Azad university at the age of 18-25 and vaccinated personnel of Borujerd Shariaty hospital were tested for Anti.HBS-Ab level by ELISA method with Radim kit (cat.KHB31). Results were analyzed according to the number of received vaccines, the duration of vaccination and demographic criteria using descriptive statistics.
Results: About 90% of samples had protective immunity and 10% were NR. 8% of immune group had more than 1000, 17.2 % between 500-1000 and 74.8 % between 10-500 miu/ml of Ab titer. About 75% of immune samples had received two vaccines. In NR group 53% had received three vaccines and 47% had two. 4% of samples were immune with the duration less than one month after vaccination which 85 % of them had two vaccines.
Conclusion: Herd immunity was 90% which is accordant to most studies. In some studies with different results the effective criteria were not differentiated. So regarding these differences, vaccinated people are recommended to evaluate their HBS.Ab level.

Introduction: Life expectancy is one of the summary measures of population health, whose values and trend of changes over time show the main outcome of health system performance. Estimation of life expectancy is performed with direct or model-based methods. In this study direct estimation of life expectancy for Iran’s population in year 2003 is performed. Materials and Methods: In an ecologic study, for calculation of abridged period life table for 23 out of 28 provinces of Iran in year 2003, numbers of registered deaths for age and sex specific groups in these 23 provinces by death registration system of Ministry of Health (MOH) were used. Undernumeration of over-four year's deaths was estimated and corrected with Brass Growth-Balance method. For mortality rates of under-one and 1-4 years, similar rates from Demographic and Health Survey (DHS) 2000 with live births denominators were substituted. For total number of population of 23 provinces, information from MOH was used. Distribution of population by age and sex was taken similar to that from DHS 2003 results, and also taken as result of graduation of whole country population from 1375 census. Population of these 23 provinces was equal to 73% of total population of country in year 2003. Life expectancy was estimated by age and sex with the obtained population and death numbers. It was assumed that distributions of population and death in 23 provinces were similar to those for the whole 28 provinces of Iran in year 2003 and hence, the estimated life expectancy for 23 provinces is equal to that for all 28 provinces in 2003. Sensitivity of the results to assumptions was analyzed. Confidence intervals were calculated with Monte Carlo method. Results: Life expectancy at birth was estimated as 71.56 years for total population (95% CI: 71.52 – 71.62), 70.09 years for males (70.02 – 70.16), and 73.17 (73.10 – 73.24) for females of Iran in year 2003. Sensitivity of results to assumptions was less than 0.5%. Conclusion: Values of life expectancy estimates for year 2003 with direct method are higher than those based on statistical modeling approaches performed by Statistical Center of Iran and by different United Nations agencies, due to difference in estimation methods for age and sex specific mortality rates.

Introduction: Celiac disease (CD) or gluten-sensitive enteropathy is a malabsoption of nutrients due to hyoersesitivity of gluten. Some etiologic facrors are environmental, immunologic and genetic factors. The frequancy of Celiac disease is not studied in western regions of Iran, therefore this study is done to determine the frequancy of Celiac disease in general population of rural regions of Arak. Materials and Methods: This is a descriptive, cross-sectional study in which 700 people between 20-56 years old in rural regions of Arak were selected by multistage random sampling (364 male and 336 female). After completing questionnaires, blood samples were collected and serum IgA levels (to rule out IgA deficiency), and serum t-TG Ab were assessed. All cases that had positive serologies and those who had high clinical probability of having Celiac disease underwent second duodenal segment biopsy. Data was presented using mean, standard deviation and frequency distribution. Results: Serum IgA levels were normal in all samples. 8 cases were positive for t-TG Ab, 38 cases had high normal levels of t-TG Ab and the others had less than 6 Au/ml t-TG Ab. Only in patients with high normal serology, histology was positive. 1% (10 in 1000 people) of all studied subjects demonstrated intestinal lesions due to Celiac disease. Most of them were asymptomatic. Conclusion: CD frequency in rural regions of Arak in people between 20-65 years old was 10 among 1000 cases. This frequency is the same as studies done in northern and southern regions of Iran but was higher comparing to the other parts of the word. This amplifiles the importance of screening of CD in Iran. Also the sensitivity and specificity of t-TG Ab was found high because all cases with high normal levels of t-TG Ab were approved by histology.

Background: Angiogenesis is a complex process that occurs in many physiologic and pathologic conditions such as invasion and metastasis of tumors. Therefore, it is the target of many clinical treatments. Rapamycin is one of the immune system inhibitor drugs that recently has been used for controlling different types of cancer. In this study, the effect of Rapamycin on angiogenesis in chicks' chorioalantoic membrane was investigated. Methods and Materials: In this experimental study, we used 42 Ross fertilized eggs that were divided into 3 random groups: control, sham-exposed (treated by Dimethyle sulfoxide-DMSO- ) and treated with Rapamycin. In 2th day, a window was opened on eggs in the sterile condition. Later, in 8th day, a gelatin sponge appeared on chorioalantoic membrane and was soaked with 5 μl Rapamycin in treatment group and 5 μl DMSO in the sham-exposed group. In 12th day, CAMs were examined and photographed by Research Photostereomicroscope in all cases. The numbers and lengths of vessels around the sponges were measured and compared with each other by T-Test (p<0.05). Results: The mean of number (42 ±7.26 ) and length (57.25±5.05 cm ) for vessels in the control group and mean of number (42.93±8.37 ) and length (55.66±10.44 cm) in sham-exposed group was'nt any significant differences. There was a significant decrease in mean number (29.36±5.28) and length (44.55±10.22) of vessels in Rapamycin with control group. Conclusion: It seems Rapamycin has an inhibitory effect on angiogenesis in chicks' chorioalantoic membrane. It decreases the number and length of vessels around treated area

Background: Multiple sclerosis (MS) is a auto-immune disease of central nervous system. The etiology of MS is unknown, but environmental factors such as viruses are involved in the development of MS. In this study, MS patients were assessed for antibodie titers against Human Herpes virus-6 (HHV-6) in Markazi Province. Methods and Materials: In this case-control study, 31 new cases of MS patients and 60 healthy subjects were selected with similar demographic criteria such as sex, age and location. Antibodies titer (IgM and IgG) against HHV-6 were examined by ELISA and Immunofluorescence methods. Data were analyzed using Logistic regression and Odds ratio. Results: Data indicates that 74.2% of case group and 34.2% of control group were identified as positive for IgM against HHV-6. The difference between the two groups in terms of IgM against HHV-6 was statistically significant (p=0.001). Incidence of IgM positivity against HHV-6 was increased more than five times in MS patients compared to control group. Also there was a statistically significant difference between case and control groups in IgG titer (p=0.019). Conclusion: Acute infection of HHV-6 is a risk factor for MS.

The aim of this study has been determined the effect of education based on Health Belief Model on self-medication in mothers referring to health centers of Arak. Materials and Methods: In this clinical trial study, 300 mothers referring to health centers of Arak were participated. Data were collected with a questionnaire based on Health Belief Model and a performance checklist about drugs intractable consumption. Before educational intervention, questionnaires and checklists for both groups were completed and then intervention was done during 1 month in 4 sessions, 60 minutes. Data again were collected and then analyzed 3 month after intervention in both groups. Results: Before educational intervention, the rate of knowledge, perceived susceptibility, severity, and benefit of self medication were in the mediate level and the mother's performance about drug intractable consumption were more than mediate. After educational intervention, between two groups had significant difference in all variables and mothers performance in self-medication was reduced (p<0.05). Conclusion: By increasing in mean score of Health Belief Model parts, including: knowledge, perceived susceptibility, severity, and benefit, performance in field of self-medication was reduced. Recommended, training based on this model carried out in other health centers for reducing drugs intractable consumption.

Background: Colorectal cancer is one of the most important and most common fatal types of cancer in the world. Identifying new agents which individually or in combination with other agents induce apoptosis in tumor cells is surely of great significance in treatment of colon cancer. The aim of the present study was to assess the effectiveness of applying lovastatin and α-tocopherol individually or in combination with each other in the induction of apoptosis in human colorectal cancer cells. Materials and Methods: In this trial, HT29 cells were exposed to various concenterations of lovastatin (5, 10, and 20 μmol) and/or alpha tocopherol (10, 20, and 25, and 30 μmol). After cell count, these cells were examined through trypan blue method and DNA fragmentation technique. Results: The findings of DNA fragmentation technique showed that each of the two drugs could induce apoptosis at all of the given concentrations. In the combination of 10 μmol concentration of lovastatin and 5 and 10 μmol concentrations of α-tocopherol, induction of apoptosis was not observed. Conclusion: Based on the extensive effects of statins, the concentration of lovastatin is seen as determining in its apoptosis function, and its combination with tocopheroles in high concentrations, by inducing apoptosis, can provide novel effective strategies for prevention of human colorectal cancer.

Background: Irritable bowel syndrome (IBS) which is characterized by chronic abdominal pain and changes in bowel movements is the most common gastrointestinal disease. Curcuma is one of the traditional medications which has been considered in treatment of gastrointestinal diseases. In this study, the effects of curcuma on IBS were investigated. Materials and Methods: In a double-blind randomized study, 140 IBS patients after meeting the inclusion and exclusion criteria, regardless of sex and age and based on internist’s diagnosis, were involved. The patients were randomly divided into case (curcuma) and control (placebo) groups which included 69 and 71 patients, respectively. For converting subjective criteria to objective ones, treatment forms were filled out before the treatment and two and four weeks after the treatment according to visual analog scale. Data were analyzed through descriptive statistics and t-test. Results: Using curcuma and placebo before the treatment and two and four weeks after that improved patients’ clinical symptoms except for vomiting (p=0.001) however, no significant differences were observed in the effectiveness of placebo and curcuma on improvement of clinical symptoms of patients in case and control groups (p>0.05). Conclusion: Using curcuma does not offer any significant differences in controlling and reducing the symptoms of IBS in comparison to the placebo, but its application improves the clinical symptoms of IBS patients.
