Abstract
Background: Adenosine receptors play an important role in the treatment of paroxysmal supraventricular tachycardia in cardiovascular system. This effect is through interaction with A1 type of G-protein-coupled adenosine receptors. The effect of N6-cyclopentyladenosine (CPA), an A1-selective adenosine agonist, was studied on ouabain-induced toxicity in spontaneously beating isolated guinea pig atria.
Methods: In the beginning the isolated guinea pig atria were mounted on the organ bath containing modified krebs and contractile responses in the four groups (shame, CPA, ouabain, CPA- ouabain) were measured.
Results: CPA (2-16nM) produced a dose-dependent decrease in the force of contractions (34%-51%) and in the rate of contractions (22%-48%). CPA significantly increased the time of onset of arrhythmia (toxicity) induced by ouabain (1.2µM) when it was administered 10 min before ouabain was added in organ bath. Ouabain (1.2µM) alone produced arrhythmia at 7 min and either asystole or standstill at 22 min. CPA (8nM) increased the time required to produce arrhythmia to 27.5 min and prolonged beating atria to more than 63 min and prevented the occurrence of asystole.
Conclusion: CPA produces direct cardiac action, probably due the inhibition of cardiac Ca2+ channel and membrane hyperpolarization of atrium cells in guinea pig atria. Moreover, our results suggest that CPA may reduce the membrane conduction through inhibition of ionic channels, which decrease ouabain- induced toxicity.

Background: American pediatric Association proposes to
screen all neonates with Oto-Acoustic Emission (OAE). In developing countries, because of several limitations,
health policy makers recommend to screen only in high risk patients. This study is performed with the aim to screen
hearing loss in 950 high risk newborns hospitalized in hospitals
affiliated to Tehran University using the OAE test.
Methods: A total of 950 neonates hospitalized in the Neonatal and NICU wards of
Vali-e-Asr, Shariati, Medical Center and Bahrami Hospitals during the years 2004-2006 who
showed at least one risk factor using TEOAE hearing test were enrolled into this cross-sectional
descriptive analytical study and were diagnosed with mild deafness and total
deafness. Blood exchange due to hyperbillirubinemia, septicemia, congenital
heart disease, the fifth minute apgar scores below six, PROM more than six hours, epilepsia, need to NICU more than five hours, pneumonia and Oto-Toxic drugs
were considered as risk factors. Data was past medical history, current
disease, admission cause, sign & symptoms and complications of disease.
Results: Multivariate logistic regression and paired t-test
showed that blood exchange, low birth weight and low first minute Apgar scores
had the highest independent risk for hearing loss among newborn.
Conclusion: Despite of the low prevalence of neonatal hearing loss,
screening of hearing loss at early stages is important.

Abstract
Background: The oncoplastic surgery has been revolutionized breast conservative surgery. The aim of our study was to represent the cosmetic outcome of oncoplastic breast surgery in Iran and to evaluate its determinants.
Methods: Fifty eight patients with unilateral breast neoplasm operated with single surgeon in Imam Khomeini Hospital, Tehran, Iran. Three view photographs were obtained pre and post operatively and were put in separate PowerPoint slides. The photographs were evaluated by six health related professionals. They scored the cosmetic outcome with modified questionnaire containing general and specific questions. Weighted kappa used for intra and inters rater reliability and ANOVA was used for analyzing cosmetic outcome determinants.
Results: Generally, 72.2% of the photographs got the excellent or good score in a single breast evaluation part. Its items breast size, nipple deviation and scar quality scored 94.2, 67.9 and 88.8 respectively. "In comparison with contra-lateral breast" part shape asymmetry, need for surgery of contra lateral breast and size asymmetry scored 68.9, 75.8 and 69% respectively. Tumor size greater than two cm had poorer outcome (p=0.039) upper outer quadrant tumor had the worst and upper inner quadrant tumors had the best outcomes (p<0.0001). Patient with 50 to 60 years of age had the poorest outcomes (p<0.0001). Weighted kappa for inter and intra rater kappa was 0.12 and 0.58 respectively.
Conclusions: Acceptable cosmetic outcome is obtained in the first experience of oncoplastic breast surgery in Iran. Long term monitoring of oncologic and cosmetic outcomes in greater numbers of patients is recommended.

Abstract
Background: Scorpion envenomation is considered as one of the Public Health problems in some countries in the world including Iran. Annually, approximately 30,000 scorpion stings happen in Iran from which 12% belongs to Hemiscorpius lepturus (special small closely spaced, bead-shaped jointed tail, similar in the shape to a cows tail, and is locally called ‘‘gaodim'' (Gao, cow dim, tail)) with 95% mortality. The main treatment is antiserum therapy which is produced in horse and is the only way to neutralize the venom. Due to the anaphylactic shock of the horse antiserum in some of the stung patients other source of antiserum is recommended. In this study the ability of produced camel antiserum in neutralizing the scorpion venom of Hemiscorpius lepturus was performed in Balb/c model.
Methods: Camel is an animal model that genetically is compatible with human genome utilized in this research to produce antiserum against scorpion venom. Two camels were used for immunization with the venom of Hemiscorpius lepturus. ELISA method was used to confirm the immunity. Antiserum was produced and used for neutralizing test. The precipitated antiserum with saturated ammonium sulfate (SAS) was also used to perform the neutralizing test in mice.
Results: The results indicated that the amount of 200 µl of antiserum and 400 µl of SAS antiserum were able to neutralize the amount of 1 LD100 of the venom and the survived the mice from death.
Conclusion: The result indicated that camel antiserum against scorpion venom is capable to neutralize the crude venom in mice model. Due to the safety of camel serum in human, it is suggested that the produced antiserum in camel can be substitute with the traditional horse antiserum in scorpion stung patients.

Abstract
Background: One of the most important components of coronary
artery bypass graft surgery is need for blood transfusion that increases
morbidity and mortality. The aim of this study was to evaluate the factors
affecting the need for blood transfusion during off pump coronary artery bypass
(OPCAB)
surgery.
Methods: In
this descriptive case control study 923
patients who had undergone OPCAB at Afshar Hospital in Yazd,
Iran, from July 2008 to January 2010
were evaluated. The data was gathered from their records and was analyzed.
Results: 54% of
male and 79% of female patient need
blood transfusion. Mean age in patients needed transfusion was 61.58±11.11
years and in other group was 60.27±10.98
years of the patients that needed transfusion (p= 0.08). 563
(61%) of the patients needed transfusion with the
average of two units. The need for blood transfusion was higher in female
gender (p< 0.0001),
low hematocrit (p< 0.0001),
diabetes (p< 0.001),
hypertension (p< 0.025)
and multiple grafts (p< 0.027).
There were no significant differences in preoperative hemostasis tests,
affection to hyperlipidemia, CVA or
renal failure, antiplatelet drug administration and the application of left internal
mammary artery between the transfusion and non transfusion groups.
Conclusion: In this study preoperative
hematocrit was most important risk factor in transfusion in patients that
underwent OPCAB. Female gender, preoperative
low hematocrit, multiple grafts, diabetes and hypertension increased the rate
of blood transfusion. According to the high prevalence of blood transfusion in OPCAB, considering factors that
affect the transfusion rate is essential.

Abstract
Background: Chronic Obstructive Pulmonary Disease (COPD) is one of the most prevalent pulmonary diseases. Use of an automatic system for the detection and diagnosis of the disease will be beneficial to the patients' treatment decision-making process. In this paper, we propose a new approach for the Computer Aided Diagnosis (CAD) of the disease and determination of its severity axial CT scan images.
Methods: In this study, 24 lung CT scans in full inspiratory and expiratory states were performed. Variations in
the normalized pattern of the lungs' external parenchyma were exploited as a feature for COPD diagnosis.Subsequently, a Bayesian classifier was used to classify variations into two normal and abnormal patterns for the discrimination of patients and healthy individuals. Finally, the accuracy of the classification was assessed
statistically.
Results: With the proposed method, the lungs parenchymal elasticity and air-trapping
were determined quantitatively. The more this feature tended to zero, the more severe air-trapping and obstructive pulmonary disease is. By analyzing CT
images in the healthy and patient groups, we calculated the hard threshold for the diagnosis of the disease. Clinical results tested by the
mentioned method, suggested the effectiveness of this approach.
Conclusion: In regard to the challenges of COPD diagnosis, we propose a new computer-aided design which may be helpful to physicians for a more accurate diagnosis of the disease. Moreover, this severity scoring algorithm may be
useful for targeted disease management and risk-adjustment.

Background: Proper drainage of the mediastinal and pleural spaces following Off-Pump Coronary
Artery Bypass (OPCAB) surgery is essential
for the prevention of pleural and pericardial effusions, cardiac tamponade and
late complications such as constrictive pericarditis. Drainage tubes themselves
may induce some complications which can negatively affect the result of the
surgery. In this study we assessed a new technique for chest drainage following
OPCAB.
Methods: In this clinical trial, 171 patients were
allocated to two groups. In the control group, the drainage technique included
one drain in the left pleural cavity and another in the mediastinum, while in
the case group the drainage technique included one drain in the left plural
and one in the right pleural cavity.
Results: The amount of drainage in the case group was more than the control group (p=0.001).
We found significant reductions in the incidence of arrhythmias in the case
group (p=0.005). While one patient (1.2%)
needed reoperation for bleeding control in the control group, no patients
needed reexploration in the case group (p=0.497).
The duration of hospital (p=0.022) and ICU
(p=0.002) stays was shorter in the case group.
Conclusions: Based
on the results of this study, changing the position of mediastinal drains in
patients undergoing OPCAB surgery and shifting it to
the right pleural cavity, reduces complications, such as arrhythmia and
pericardial effusion, aside from establishing a better drainage.

Abstract
Background: In recent years, consumption of whole-blood for the treatment of patients has decreased but use of biological plasma-derived medicines such as albumin, immunoglobulin and coagulation factors have increased instead. Paying attention to albumin molecular structure is important for its isolation from human plasma. Albumin is a single-chain protein consisting of about 585 amino acids and a molecular weight of 66500 Daltons. Albumin is a stable molecule and it is spherical in shape. There are different methods for human albumin preparation. Considering the large consumption of this biological drug in clinical settings, methods with fewer steps in production line are of big advantage in saving time and manufacturing more products.
Methods: In this project, we prepared human albumin using hollow fiber cartridges in order to omit the rework on fraction V+VI. Human albumin is usually produced by the application of cold ethanol method, where albumin is obtained from fraction V by doing a rework on fraction V+VI to separate fraction V.
Results: In the current work, human albumin was prepared from fraction V+VI by the help of hollow fiber cartridges. With a concentration of 20%, the obtained albumin had 96.5% of monomer and 3.5% of polymer and polymer aggregate.
Conclusion: Comparing the obtained human albumin with a number of commercial human albumin samples by the use of SDS-page, the results were satisfactory regarding the 3.5 percent polymer and aggregate rate for the prepared albumin.

Background: The
goal of this study was to compare the efficacy of botulinum toxin type A (BTX-A) injection in the hamstring
and calf muscles with and without ankle serial casting in the improvement of
gait in children with cerebral palsy (CP).
Methods : This double-blind prospective clinical trial was performed on 25, 2 to 8-year-old children with
hemiplegic or diplegic CP in Tehran, Iran in 2010. The participants were chosen by simple randomized sampling and
were matched for age, gross motor function classification system (GMFCS) and type of CP and were randomly divided
into two groups: children in the first group (13) only received BTX-A injection, but the second group (12) received BTX-A and serial foot casting starting one week after the injection.
Results : Comparison of the gross motor function, right and left knee
spasticities and passive ROM of both knees between the two groups before and 1, 3, 6 and 12 months after the injections
were not statistically significant (P>0.1). Furthermore, comparison of the right and left ankle spasticities
and passive ROM before the injections and in1 and 3-month follow-ups did not show a statistically significant difference
(P>0.1),
but the differences were significant in 6 and 12-month follow-ups (P<0.05).
Conclusion: BTX-A injection
with serial foot casting vs. BTX-A
alone was more effective in decreasing spasticity and improving passive ROM in
the ankle of children with CP, but such injections in the
hamstrings were not useful in these regards.

Background: Nocardiosis is a rare and potentially
life-threatening infection caused by several species of the Nocardia genus. The objective of this study was to develop and evaluate a rapid and new method to clinically identify relevant Nocardia species. Rapid and accurate diagnosis of Nocardia species is essential
for the treatment of severe infections and prevention of cerebral abscess.
Methods: One hundred and eighty patients, 103 (57.22%) male and 77 (42.78%) female, with severe symptomatic
pulmonary infection were studied in the course of a 12-month period in Dr.
Shariati Teaching Hospital affiliated to Tehran University of Medical Sciences
in 2010. The specimens were cultured and identified
using microbiological and biochemical tests. Polymerase chain reaction (PCR) was used to directly identify the organism in the
broncoalveolar lavage samples collected from the patients. NG1 and NG2 primers were used to amplify a Nocardia genus-specific 598-bp fragment of 16S rRNA.
Results: Nineteen samples (10.56%) were positive with PCR and 5 samples (2.78%) with conventional methods. All
samples with positive cultures were also positive by PCR.
Conclusion: The results of this study showed that PCR has a high
sensitivity and accuracy for the detection of Nocardia compared with
culture and biochemical tests. Considering the rapidity, precision, high
sensitivity and specificity of molecular techniques, use of these techniques is
suggested in conjunction with conventional methods for the detection of Nocardia phenotypes in clinical laboratories and research centers.

Abstract
Background: Fumonisins, a family of mycotoxins, are mainly found in wheat, corn and their products. Previous studies have shown that fumonisin B1 (FB1), the most abundant and toxic of known fumonisins, has been associated with many animal and human diseases including cancer. In the present study, the effects of FB1 were examined on the production of inflammatory cytokines in intestine and stomach cell lines.
Methods: This study was performed in the Cancer Research Center of Tehran University of Medical Sciences in 2010. The cell lines of colon adenocarcinoma (SW742) and gastric epithelium (AGS) were purchased from the Pasteur Institute of Iran. The cells were pretreated with different concentrations of FB1 (0 to 100 µM) for 3 days. The cells were later stimulated by lipopolysaccharides. Twenty-four hours after cell induction, the cytokines including tumor necrosis factor-alpha (TNF-α), interlukin-1 beta (IL-1β) and interlukin-8 (IL-8) were measured by ELISA.
Results: Treatment with FB1 induced a dose-dependent decrease in IL-8 production (P<0.05). This decrease was seen in both SW742 and AGS cell lines. Moreover, FB1 induced a dose-dependent increase in the production of TNF-α and IL-1β in both cell lines (P<0.05).
Conclusion: The results of this study indicated that FB1 could increase the inflammatory cytokines including TNF-α and IL-1β in gastric and intestinal celllines. These effects might result in the development of inflammatory responses and subsequent mucosal atrophy in in-vivo conditions.

Abstract
Background: Ovarian hyper stimulation syndrome (OHSS) and its consequences, especially thromboembolic events, are of the most dangerous complications of assisted reproductive technologies (ART). It is unclear whether a thrombophilic predisposition or changes in blood components during clinical presentation of OHSS increase thrombotic risks. Testing for certain thrombophilias in selected high risk patients may help risk assessment and decision-making about prophylactic measures.
Methods: In this study carried out in April 2010 to March 2011, 108 in vitro fertilization candidates with ≥20 follicles following ovarian stimulation were recruited. Protein S, protein C, antithrombin, lupus anticoagulant and anticardiolipin antibodies were measured. Blood tests were compared between severe and non-severe OHSS groups and their changes were traced after onset of clinical OHSS in 43 patients presenting with severe symptoms by repeating the tests at hospital admission.
Results: Mean protein S activity was lower in severe OHSS group (101.7±16.3 vs. 118.4±17.0 P<0.001). After clinical presentation of severe OHSS, this level decreased to 91.6±20.1 (P<0.001). Antithrombin levels decreased 2.09% after the onset of symptoms in the group with severe OHSS, but this difference was not statistically significant (P=0.051). Protein C, lupus anticoagulant and anticardiolipin antibodies were not correlated to severe OHSS development.
Conclusion: Patients with relatively lower protein S activity were at higher risk for the development of severe OHSS, and its dangerous consequences. During clinical OHSS presentation, protein S decreased even more, and patients were more vulnerable to hypercoagulability states. These points should be kept in mind in risk assessment and adoption of prophylactic strategies.

Abstract
Background: The basal levels of androgens in women decline gradually with age. These changes may reduce muscle strength and bone density leading to fatigue and psychological problems. Thus, the aim of this study was to compare the effects of resistance and endurance exercises on androgens, cortisol and lactate concentrations in elderly women.
Methods: In this study, 10 elderly women with a mean age of 54.3±3.74 years and a BMI of 24.88±2.07 kg/m2 completed an endurance exercise session (ES), a resistance exercise session (RS), and a control session (CS) in a randomized, cross-balanced design. The RS consisted of three sets of 10 repetitions of eight exercises with 80% 1RM (one repetition maximum) over of 45 minutes and the ES consisted of cycling at 60%-70% of maximum oxygen consumption for 45 minutes. During the CS, subjects performed no exercise. Before and immediately after exercises, and after 15 minutes of recovery, and also during CS blood samples were obtained an analyzed for serum testosterone, dehydroepiandrosterone sulfate, cortisol and lactate.
Results: There was a significant increase in testosterone levels following resistance and endurance exercise sessions (P<0.05). Dehydroepiandrosterone sulfate demonstrated a significant increase after resistance exercise (P<0.05). While differences in cortisol levels were not significant within groups, but they were significant (P<0.05) between groups.
Conclusion: A session of resistance exercise in elderly women can increase concentrations of androgens that are essential for their health and well-being.

Abstract
Background: Lung diseases and lung cancer are among the most dangerous diseases with high mortality in both men and women. Lung nodules are abnormal pulmonary masses and are among major lung symptoms. A Computer Aided Diagnosis (CAD) system may play an important role in accurate and early detection of lung nodules. This article presents a new CAD system for lung nodule detection from chest computed tomography (CT) images.
Methods: Twenty-five adult patients with lung nodules in their CT scan images presented to the National Research Institute of Tuberculosis and Lung Disease, Masih Daneshvari Hospital, Tehran, Iran in 2011-2012 were enrolled in the study. The patients were randomly assigned into two experimental (9 female, 6 male, mean age 43±5.63 yrs) and control (6 female, 4 male, mean age 39±4.91 yrs) groups. A fully-automatic method was developed for detecting lung nodules by employing medical image processing and analysis and statistical pattern recognition algorithms.
Results: Using segmentation methods, the lung parenchyma was extracted from 2-D CT images. Then, candidate regions were labeled in pseudo-color images. In the next step, some features of lung nodules were extracted. Finally, an artificial feed forward neural network was used for classification of nodules.
Conclusion: Considering the complexity and different shapes of lung nodules and large number of CT images to evaluate, finding lung nodules are difficult and time consuming for physicians and include human error. Experimental results showed the accuracy of the proposed method to be appropriate (P<0.05) for lung nodule detection.

Abstract
Background: Anti-Müllerian Hormone (AMH) is secreted from granulosa cells of growing follicles and is a useful marker of ovarian reserve. Fertility in women is determined by the quality and quantity of follicle pool and ovarian follicular reserve positively correlates with AMH. In this study we aimed to determine if AMH can predict ovarian response in IVF treatments.
Methods: In this retrospective observational study undertaken in Mehr Institute during 2010 to 2011, we studied the medical records of 101 patients and recorded the concentrations of AMH, day two or three FSH, LH, basal estradiol (E2), E2 on day of HCG administration and the number of metaphase II oocytes. Having undergone ovarian hyperstimulation, the women were divided into three groups: poor responders (retrieved oocytes ?3), normal responders (retrieved oocytes 4 to 15) and high responders (retrieved oocytes ?16).
Results: Overall, 20% of patients were defined as poor responders, 71% as average responders and 10% as high responders. There were significant differences in the concentration of AMH, E2 on day of HCG administration, FSH, the number of metaphase II oocytes and age between the three groups. MII oocyte count correlated positively with AMH (r=0.487), basal E2 (r=0.275) and LH (r=0.07) but it did negatively with FSH (r=-0.26) and age (r=-0.04). The areas under curve for AMH, FSH, LH, E2 and age were 0.799, 0.32, 0.429, 0.558 and 0.304, respectively. We determined the 0.85 ng/ml AMH concentration as the cut-off point with 71% specificity and 79% sensitivity for the prediction of poor responders.
Conclusion: anti-müllerian hormone is an appropriate predicator of ovarian response following induction of ovulation.

Abstract
Background: In molar pregnancy, when hydatidiform changes are local and some embryonic components are observed, the term of partial mole is used. The risk of persistent trophoblastic tumor after partial mole is much lower than complete mole. In this persistent cases almost all are non metastatic. The aim of this study is to report a case of uterine rupture following incomplete molar pregnancy.
Case presentation: The patient was a 26 year old woman with obstetric history of an abortion and one molar pregnancy and no child. She was referred to emergency unit in Ghaem University Hospital, Mashhad, Iran in May 2011. She had an evacuation curettage following molar pregnancy three months before and without any follow up visit. The patient was referred to emergency unit with hemorrhagic shock. She immediately underwent laparotomy. The uterine fundal rupture was repaired and evacuation curettage performed. In post operative evaluation, she had a nine millimeter metastatic nodule in base of right Lung. As a patient in low risk stage III, she received weekly intramuscular methotrexate (40mg/m2) for six courses. In follow up visit -hCG titer was negative (<10miu/ml) at 5th week.
Conclusion: In cases of in complete molar pregnancy risk of metastasis is very low. Serial beta-hCG titer is the most accurate method for detection of persistent gestational trophoblastic disease (GTN). In neglected cases like this case preservation of ruptured uterus in GTN is possible.

Abstract
Background: Today, a CT scan examination play an important role in disease diagnosis and thus allocates a significant dose of medical X-ray examinations. One of the important principles in the use of ionizing radiations is to observe radiation protection principles. Evaluating patient's absorbed dose and implementing the strategies for reducing dose are prior in safety issues. To achieve this purpose, sufficient studies should be performed in this regard. Therefore, patient's absorbed dose and the factors affecting have been studied in this research. This study aims to present and develop an acceptable level of absorbed dose in CT scan examinations.
Methods: Diagnostic reference dose level in the adult age group (older than 15 years) has been studied in eleven CT scan centers in Tehran. For this purpose, CT scan examinations prevalent in above-mentioned centers were chosen and Weighted Computed Tomography dose index (CTDIw) and dose length product (DLP) parameters were studied. Standard phantoms with 16 and 32 diameters of Polymethylmethacrylate (PMMA) origin have been used in the centers for CT scan calibration process. CTDIw third quartile has been considered as the diagnostic reference dose level (DRL).
Results: Rate of diagnostic reference dose in the adult age group (older than 15 years) for the head, sinus, lungs, abdomen and pelvis are 50.87, 38.27, 8.05 and 9.11 mg, respectively. Dose measurements made in this survey have been used to set up local DRLs and can be used as a template for national DRLs.
Conclusion: Value of diagnostic reference dose for the head examinations is more than the other parts and diagnostic reference dose in Tehran city in the Adult age group and the protocols compared is less than national reference dose.

Abstract
Background: Body dysmorphic disorder (BDD) is characterized by a preoccupation with an imagined defect in ones appearance or an exaggeration of a slight physical anomaly. Any part of the appearance may be the focuse of BDD patients. Thus preoccupation with appearance leads to significant damages of social and job functioning. The aim of this study is to determine the prevalence of BDD in patients referred to cosmetic clinic of Razi hospital.
Methods: Patients visiting cosmetic clinic of Razi hospital were selected if they agreed to participate in the study. They were evaluated by Yale brown obsessive compulsive scale modified for body dysmorphic disorder (YBOCS-BDD) as well as questionnaires containing demographic characteristics of patients including gender, educational status, marital status, history of reference to psychiatrist or psychologist, other medication, history of cosmetic surgery and rate of satisfaction of cosmetic surgery. YBOCS-BDD questionnaires then processed by educated specialist to determine BDD score of patie-nts. Demographic questionnaires, also analysed to evaluate epidemiologic properties of patients visiting cosmetic clinic of Razi hospital.
Results: The prevalence of BDD in current sample was 33.3%. 70.7% of BDD patients were female while 29.3% were male. The commonest age range was 21-50 years (82.8%). 65.5% were educated to level of diploma or lower, while 34.5% had academic degrees. 51.7% were married. 20.7% had history of reference to psychiatrist or psycholo-gist. 17/2% had history of cosmetic surgery with satisfaction ranging from unsatisfied (20%) to relative satisfaction (80%). None were fully satisfied.
Conclusion: BDD had high prevalence in patients visiting cosmetic clinic of Razi skin hospital. This high rate of prevalence show the necessity of diagnosis of BDD in skin patients and it is critical for them to refer to psychiatrists or psychologists.

Abstract
Background: Alopecia areata (AA) is a common cause of noncicatricial alopecia that occurs as a patchy, confluent or diffuse pattern. Exact etiologic factor of AA not yet recognized. Among many hypothesis, relationship between AA and autoimmune disease, especially thyroid disorders, was more interesting. The objective of this study was to determine the prevalence of thyroid test disorders in the patients with alopecia totalis and universalis in comparison with normal population.
Methods: We analyzed medical records of 100 patients, including 44 male and 56 female in Tehran Razi Hospital from 1388 to 1389. The mean age was 24.1 years. Patients having totalis and universalis form of AA considered as case group while 100 normal person (42 male and 58 female with mean age of 26.1) who had not any form of AA considered as control group. Both groups had not any sign of thyroid disease at clinical examination according to their available medical records. Collected data were analyzed statistically in SPSS software 17th version.
Results: In the majority of patients (54%) the disease was manifested in the first two decades of life. History of atopia was seen in 9.8% of patient. Presence of the similar disease in first-degree family members was seen in 14.3% of patients. Abnormal T3, T4 and TSH were significantly higher in case group. Abnormal T3 uptake was higher in case group but not statistically significant.
Conclusion: Paraclinical thyroid disorders were significantly higher in the alopecia areata patients than in normal population. There was no significant association between the age, sex and duration of disease and presence thyroid dysfunction.

Abstract
Background: As regard to high prevalence of Helicobacter pylori infection and complications of it's persistence, as well as anti-bacterial activity against of Helicobacter pylori and anti-inflammatory properties of omega-3 fatty acids, this study was conducted to evaluate the effects of supplementation with Docosahexaenoic Acid (DHA) on the eradication of Helicobacter pylori infection, some serum inflammatory markers and total antioxidant capacity.
Methods: In a double-blind, placebo-controlled clinical trial, 66 H. pylori positive patients (33 in the intervention group and 33 in the control group), along with tetra-drugs H. pylori eradication regimen, randomly received daily two grams morDHA supplement or Medium Chain Triglyceride (MCT) oil as placebo for 12 weeks. Dietary intake data was collected by 24 hour food recall and analyzed by Nutritionist IV software. Sampling from fasting blood and measuring weight, height, body mass index (BMI) and level of physical activity were done at the first and the end of the study. As well as, eradication test of the infection was performed for all patients at the end of the intervention.
Results: Eradication rate of the infection, the level of interleukin-6 (IL-6), high sensitivity C-reactive protein (hs-CRP) and total antioxidant capacity (TAC) didn't have significant difference between two groups at the end of the study (P>0.05), while the level of interleukin-8 (IL-8) was different between two groups (P=0.008). Difference of the concentration between the beginning and the end of the study was not significant in any factors between two groups (P>0.05).
Conclusion: Intake of morDHA supplement didn't have significant effect on the eradication of H. pylori, serum levels of IL-6, hs-CRP and TAC, while it was effective on the level of IL-8.
