Introduction: Fasting during Ramadan is a religious obligation and belief for healthy and adult Moslems. The aim of the study was to determine the effects of Ramadan fasting and physical activity on blood hematological-biochemical parameters. Methods: In this study twenty six healthy males were assigned into two experimental groups, non-active fasting (13 people) and active fasting (13 people) groups. Two blood samples were taken from each group at the beginning and end of Ramadan. The data was analyzed through repeated measure ANOVA.

Background and Objective: Infection with HBV is the most common chronic viral infection and mortality in children. Prevention of this infection with vaccination is vital. This study was done to compare the antibody level in post hepatitis B vaccination in children with 12-15 and 21-24 months age. Materials and Methods:This descriptive study was carreid out on 186 children with 12-15 (group I) and 21-24 (group II) months age who had not infected with hepatitis B infection in, Bandarabbas Iran during 2009. The parents were HbsAg negative, without immunodeficiency diseases and did not receive hepatitis vaccination, blood or blood products transfusion. Age, gender, birth weight, breast feeding duration and gestational age were recorded for each child. Hepatitis B antibody level was measured with ELISA method. Data were analyzed using SPSS-16 and student t-test. Results: Antibody level in group I (231 mIU/ml) was significantly higher than group II (142.9 mIU/ml) (P<0.05). There was not significant differences between males and females. Antibody level was not significantly corrolated with body weight, gestational age and breast feeding duration. Antibody level lower than 10 mIU/ml were observed in 4.34% of group I and 20.8% of group II. This differnce was significant (P<0.05). Conclusion: This study showed that the protective effect of vaccination reduced after six months of final dosage.
Background and aim: It is necessary to state total information about the design, procedures, intervention groups in study, results for data in order to present a suitable report of controlled randomized clinical trial. This study was aimed to evaluate the quality of materials and methods for the writings of final proposal in clinical trial studies in Shahrekord University of Medical Sciences. Methods: In this descriptive-analytic study, 53 approved final proposals of controlled randomized clinical trial studies in Shahrekord University of Medical Sciences were selected from 1998 to 2013. The selection and quality of material and method writing was evaluated based on final version of consort checklist. Results: The scores mean was obtained for the quality of materials and methods writings based on the checklist 6.75±1.92. The notation of interventions in each group (%96.2), identification of primary and secondary study (%88.7), and the state of statistical ways (% 86.8) showed the most scores and the randomizing the least score (%3.8). The projects which were the student theses rather than not being thesis (p=0.011). Conclusion: Performed clinical trials in Shahrekord University of Medical Sciences aren't in a suitable report way. So, it is advised to provide a standard consort instruction and was delivered to researchers, reviewers, and statistical counselors in order to design study and report clinical trial studies.
ارزیابی خصوصیات میکروبی و فیزیکوشیمیایی نوشیدنی شیرفندق بر پایه آب پنیر تخمیر شده با دانه کفیر

فندق و محصولاتی که از آن بهدست میآید، از جمله شیرفندق، بهدلیل داشتن اسیدهای چرب غیر اشباع و فیتواسترولها باعث کاهش بیمارهای قلبی و عروقی می‌شوند. تخمیر محصولات با استفاده از میکروارگانیسمهای پروبیوتیک دانه کفیر سبب افزایش خواص فراسودمندی این محصولات خواهند شد. هدف از این مطالعه، تولید یک نوشیدنی تخمیری جدید از فندق با استفاده از دانه کفیر است. در این مطالعه برای تولید شیرفندق، بهجای آب از آب پنیر استفاده شد و اثر سطوح مختلف تلقیح دانه کفیر (2، 5 و 8 درصد) و دما (20، 25 و 30 درجه سلسیوس) روی خصوصیات فیزیکوشیمیایی (قدرت آنتی‌اکسیدانی، pH، ویسکوزیته و میزان کفیران) و میکروبی (تعداد باکتریهای اسید لاکتیک و مخمر) شیرفندق تخمیری مورد ارزیابی قرار گرفت. نتایج نشان میدهد که بالاترین قدرت آنتی‌اکسیدانی (8/91 درصد)، بیشترین میزان کفیران (معادل 2/8±8/152میکروگرم گلوکز)، بیشترین ویسکوزیته و بیشترین تعداد میکروارگانیسمهای پروبیوتیک (باکتریهای اسید لاکتیک و مخمرها) در نمونههای با 8 درصد تلقیح دیده میشود. بهعلاوه مشاهده شد که بیشترین تغییرات در فعالیت آنتی‌اکسیدانی، تعداد باکت...

The effect of removal of smear layer has already been a subject in many investigations, and has been a matter of controversy. Of course there is no doubt that sealer penetration would be facilitated when smear layer removed. The aim of this study was evaluation of the relationship between sealer penetration and apical microleakage after usage of MTAD. Materials & Methods: In this invitro study, 135 human single root extracted teeth were selected. The teeth were divided into three groups (40 samples in each) as experimental groups as follow: Group 1: Serum was used for irrigation (with the smear layer). Group 2: EDTA 17% was used for irrigation (removal of the smear layer). Group 3: MTAD was used for irrigation (removal of the smear layer) and 15 teeth were considered as the control. The teeth in each group were divided into two subgroups (20 teeth) to be filled either with AH Plus or Dorifill sealer. Sixty teeth were selected for dye penetration with methylene blue and statistically analysed using One-Way and Two-Way ANOVA. In the other 60 teeth, sealer penetration was evaluated using SEM. The data were statistically analysed using Kruskal-Wallis and Mann-Whitney tests. The end relationship between dye penetration and sealer penetration was evaluated by spearman correlation test. Results: There was no significant difference between the three types of irrigants. There was a significant difference between the two sealers. AH plus revealed less dye penetration. Minimum dye penetration was observed in MTAD group with AH Plus and maximum dye penetration was observed in Serum group with Dorifill. Sealer penetration in MTAD and EDTA groups were better than Serum group. AH Plus was better than Dorifill. The correlation between sealer penetration in dentinal tubules and dye penetration wasn't statistically significant. Conclusion: Type of irrigant didn't affect apical microleakage but type of sealer affected microleakage. AH Plus proved to be better. AH Plus showed greater sealer penetration. Greater sealer penetration does not necessarily reduce apical microleakage.
