Abstract
مقدمه: پرسنل بهداشتی و دانشجویان پزشکی در مقایسه با سایر گروههای جامعه به دلیل مواجهه مکرر با بیماران و فرآورده های خونی و نیز ترشحات قسمت های مختلف بدن در ریسک بالاتر ابتلاء به بیماریهای عفونی از جمله هپاتیت B قرار دارند (1). یکی از راههای پیشگیری، مصون سازی توسط واکسیناسیون علیه این بیماریها است. هدف از این مطالعه، تعیین سطح آنتی بادی ضد ویروس هپاتیت B پس از واکسیناسیون بود (1).
مواد و روشها: این مطالعه توصیفی ـ مقطعی بر روی تعداد 36 نفر از اینترن های دانشگاه علوم پزشکی لرستان که 3 دوز واکسن را به صورت کامل دریافت نموده و از آخرین زمان تزریق آنها حداکثر 6 سال گذشته است، انجام شد. نمونه های خون گرفته شده از لحاظ سطح آنتی بادی ضد ویروس هپاتیت B به طریقه الیزا بررسی شدند.
یافته ها: نتایج حاکی از آن بود که 4/44 درصد اینترنها پاسخ ایمنی متوسط و در حد قابل قبول نسبت به واکسیناسیون داشته (MIU 10 MIU > HBs Ab > 100) و 6/55 درصد اینترنها از سطح ایمنی خوبی نسبت به واکسیناسیون برخوردار بودند (MIU < 100).
عدم پاسخ به واکسیناسیون در هیچ کدام از اینترن ها مشاهده نشد (MIU 10 <). بین سطح آنتی بادی ضد هپاتیت B (HBs Ab)، گروه سنی، جنسیت، فاصله آخرین تزریق واکسن و نیز رعایت فواصل بین تزریق 3 دوز واکسن رابطه معنی داری بدست نیامد.
نتیجه گیری:کل نتایج بیانگر پاسخ ایمنی مناسب و قابل قبول در اینترنهای تحت مطالعه نسبت به دریافت 3 دوز واکسن
بود.

Abstract
Background: The nuclear medicine systems are very sensitive to the variation of the
magnetic field. Photomultiplier tubes amplify low energy light signal and change it
into electrical current. Low magnetic field can produce some variations in uniformity
and special resolution of SPECT systems. In this study, we tried to evaluate the
effects of magnetic field on the function of nuclear medicine imaging system, when
system rotates in different angles.
Materials and Methods: In this study, three SPECT systems with different
orientation were examined. A point and line source was placed in the front of the
system and when the gantry system rotated in earth magnetic field, variation of energy
photo peak, spatial resolution and linearity were determined in different angles. These
measurements repeated when an air conditioner was placed at 2-meter distance of the
camera gantries. Results were compared using t-student test.
Findings: The t-test results show that in all three SPECT systems, the variations of
energy photo peak, spatial resolution and linearity were statistically significant
(p<0.01). The surrounding magnetic field can effect on accurate function of nuclear
medicine systems.
Conclusion: The surrounding magnetic field can effect on accurate function of
nuclear medicine systems.

An increase in Intra-Epithelial Lymphocytes (IELs) is important in the diagnosis of CD and even in the presence of normal villous architecture may reflect gluten intolerance. The aim of this study was the comparison of two different histological staining Methods (H&E and IHC) for the quantization of duodenal IELs. Materials and methods: This cross–sectional study was performed on 74 duodenal samples from April 2004 to September 2004 at Shariati hospital. All biopsies were stained with H&E and IHC Methods (LCA) and each one was twice examined for the quantization of IELs by pathologist taking use of single blinding. Results: The mean number of IELs/100 epithelial cells in the first and second observations was 15.77 and 16.72 on H&E stained sections whereas it was 21.54 and 21.18 on IHC study. There was a linear correlation between IELs in H&E and IHC Methods. The comparison of mean IELs on H&E and LCA stained slides revealed about 5 cells preference for LCA. Conclusion: Two-step analysis of IELs quantization was suggested: 1) Estimation of IELs on H&E stained sections, and 2) LCA staining and counting, if IELs are suspected (upper limit of normal). When IHC staining was not performed it was possible to use the following formula: IELs on H&E +5 IELs on IHC

Abstract
Background: Functional movement screening (FMS) is a tool that could be used to determine the individual's potential for developing musculoskeletal abnormalities and sports injuries. FMS tests include seven functional movement tests that evaluate the trunk, power and central stability, neuromuscular coordination, and motor as well as flexibility asymmetries. The present study aimed at determining the functional movement screening scores in 15-17 year-old male students in Lorestan province.
Materials and Methods: The research method was based on the nature and method of collecting cross-sectional and purposeful data. For this purpose, 370 male students were evaluated by performing 7 FMS tests.
Results: The mean composite FMS score was 15.16 ± 1.79, 16.15 ± 1.91, and 16.17 ± 1.75 in 15, 16 and 17-year-old students. It could be stated that the FMS score in this statistical population is better than the related studies in this age group. Moreover, the test pattern separately showed that 80% of the population lacked sufficient stability in the central region of the trunk.
Conclusion: In many sports activities, movements of the upper and lower extremities require sufficient stability in the central region. If there is no stability in this region, energy transfer does not occur properly. This age group is close to commence official sports competition. Furthermore, the clinical efficiency of FMS has been limited by the lack of score index in Iran. Hence, sports medicine experts and sports team instructors can use the values of the norm scores to identify the people who are exposed to the risk of physical abnormality and injury at different ages. Moreover, they can use them to schedule fitness and corrective exercises.
