In this research, an effect of vitamin A on limb bud development of Balb/C mouse was determined. Materials and Methods: In this experimental study, 10 female pregnant mice were divided to control and experimental groups. Control mice were maintained in natural situation and experimental mice were received vitamin A 15000IU/kg intraperitoneal injection at gestational day 10.5. Control and experimental mice were dissected in day 15.5 of gestation and after a morphology study their embryos were prepared for histological studies with microscope and were stained by Hematoxylin & Eosin method. Results: Comparison of crown- rump length, fore limb width, length of zone 1 (finger and palm) and zone 2 (wrist) of fore limb and total length of hind limb in experimental embryos with control group didn’t have significant difference in means. But, mean of embryos weights and length of total fore limb and length zone 3 (arm and forearm) of experimental embryos fore limb were more then control (p<0.001). Also, in comparison mean of hind limb width of experimental to contol embryos, increase was observed (p0.05). Conclusion: Concentration of 15000IU/kg vitamin A has progressive effects on the fetuses’ weight and fore limb bud development of Balb/C mouse. 296 Cardiology Prevalence and clinical value of ST-segment elevation in posterior electrocardiography leads during acute myocardial infarction, Shahid Rajaei hospital, Tehran, 2003 Khadir Sharabiany Valiollah Oraii Saeed 1 10 2009 12 3 23 28 24 04 2009 Abstract Background: Current electrocardiography (ECG) criteria are insensitive for the detection of posterior acute myocardial infarction (AMI) and most of these cases remain undiagnosed. The purpose of this study has been evaluated of prevalence and clinical value of ST-segment in posterior electrocardiography leads during acute myocardial infarction. Materials and Methods: In cross- sectional analytic study, posterior ECG leads (V7, V8 and V9) as well as standard 12 leads in 210 consecutive patients with acute myocardial infarction admitted to CCU wards of Shahid Rijaie hospital. Reinforcing, continuous arrhythmia, hypotension, cardiologic shock, marked heart failure and/or acute pulmonary edema were considered. Related parameters to basic characteristics and next process of patients in two groups with/ without ST- segment elevation in posterior ECG lead were compared. Results: There were 153 patients with ST-segment elevation 1 mm in 2 contiguous leads. 12.4% patients had STE1 mm in 2 posterior leads, either as an isolated finding (4.6%) or in association with STE at inferior or lateral sites (7.8%). The standard 12-lead electrocardiogram was normal in two patients and 5 other patients were admitted with the diagnosis of non-Q infarctions. Tall R waves in V1/V2 developed in 5 cases. In-hospital complications were significantly more frequent among patients with STE in posterior leads (47.4% vs. 20.9% respectively, P=0.01). Conclusion: STE in posterior electrocardiography leads is not uncommon during acute myocardial infarction and may portend a worse in-hospital course. 335 Basic Sciences The wound healing effect of Medicago sativa extract on pinna rabbit cartilage Khayatzadeh Jina Rafiei Hossein Farhoodi Majid 1 10 2009 12 3 29 38 01 06 2009 Abstract Background: Cartilaginous and movement diseases are the most prevalent problem in human. Various vitamins like A and C increase the process of regeneration and wound healing. In this research, the Alfalfa plant with scientific name Medicago sativa, that contains a lot amount of A, C, E and K vitamins, was used and effect of its extract on regeneration of pinna rabbit cartilage was studied. Materials and Methods: In this experimental laboratory study, 6 New Zealand male rabbits with 2.5-3 kg weight have been selected. After shaving hairs on ears with depilation cream, the ear were anesthetized by lidocaine 10% and 4 holes were punched with 4 mm diameter in medial situation of each ear. Test ears by extract of Medicago sativa and control ear were treated by normal saline every day. Holes era and the distance of two edges of cartilage were measured in various days of healing. Also, tissue sampling for microscopic observation by H;E color (day 0-50) was done. Results: Regeneration and healing of the treated holes with extract of Medicago sativa was faster than the control holes (p<0/004). Also, thickness of cartilage and cell density of chondrocytes and fibroblasts in the newly formed connective tissues in test were more than control. Conclusion: The extract of Medicago sativa because of A, C vitamins containing, probably increased the wound healing and regeneration of the rabbit ear cartilage and suggest the pharmacological usages. 438 Basic Sciences Cell death in motor neurons of cultured spinal cord slices in adult mouse Soleimani Mehranjani Malek Momeni Hamid Reza Abnosi Mohammad Hosein Nasimi Parva 1 10 2009 12 3 39 46 29 08 2009 Abstract Background: Spinal cord slices culturing from adult mammals could be considered as a suitable in-vitro model for evaluating cellular viability, spinal cord injury and cell death mechanisms. In present study, determining of cell death in motor neurons of cultured spinal cord slices in adult mouse was done.

Chronic low dose methanol ingestion can cause severe toxicity. There are many unpublished reports from doctors about side effects of toxicity by methanol like blinding in chronic user of herbal essences. Regarding to kinds of herbal essences producing and side effects of its chronic using, probability, there is methanol in the process of making. Therefore we decided to evaluate rate of methanol in various products. Materials and Methods: In this cross-sectional analytic study, 3 samples of high consumption homemade herbal essences in Arak (Pussy, Mint, Fenugreek, Hedysarum, Dill and Chicory) and 3 samples of the same herbal essences from industrial products with trademarks were gathered. All of them have been analyzed with spectrophotometer in five times. Results: The maximum methanol concentration was related to a sample of industrial Mint (415.04 ppm) and the minimum methanol concentration was related to a sample of handmade Fenugreek (60.26 ppm). There was no significant difference between methanol concentration in handmade and industrial herbal essences. Conclusion: There is probability of methanol toxicity after chronic usage of some herbal essences. Due to lack of maximum permissible concentration for non methanol essences, it is recommended that a cut of point of methanol concentration was determined and inform people about it. 330 Basic Sciences Numerical and structural chromosome aberrations in aborted fetuses with using fetal cell culture and staining with GTG Banding method Tabatabaei Seyed mahmod Baghi nia Mahmoud Reza Beirami Mansor Malekirad Ali akbar 1 10 2009 12 3 92 100 31 05 2009 Abstract Background: Approximately 15-20% of pregnancies terminate to abortion. More than 50% of spontaneous abortions in 8-15 weeks pregnant mothers are related to genetically abnormalities. So, approximately 95% of them are related to numerical and 5% structural chromosome aberrations. Until now, neither of known human chromosomal abnormalities are treatable, and only way against these diseases limit to prenatal diagnosis and abortion of affected fetuses. The purpose of this study was determined the chromosome aberrations with cytogenetically methods. Materials and Methods: In this cross-sectional analytic study, 56 aborted fetuses were studied to detection of abnormalities frequency. Amnion-chorine culture, placenta, fetal tissue and aborted products from metaphase cells for gathering metaphase cells were used. Results: After cell culture, chromosome typing and GTG-banding Technique, trisomy 21 with highest frequency (12.5%) and isochromosomy 21, X and monosomy X with lowest frequency (1.8% for each them) was resulted. Conclusion: Not only chromosomal aberrations have important role in recurrent miscarriages, but also frequency rates of chromosomal aberrations in our country are similarity with other countries. Also cytogenetically diagnostic methods such as GTG-banding are a powerful and reliable technique for investigation of parents with recurrent abortion. 336 Basic Sciences The neuroprotective effect of CSF intraperitoneal injection on alpha motor degeneration after sciatic nerve compression in rat Tehranipour Maryam Bahar ara Javad Mostafaee Maryam 1 10 2009 12 3 101 108 01 06 2009 Abstract Background: Fetal Cerebrospinal fluid (CSF) develops viability and proliferation of nerve cells. Also this fluid contains many valuable factors for protection of nervous system injury cells. In this research, the effect of cerebrospinal fluid intraperitoneal injection on alpha motor degeneration after sciatic nerve compression in rat was determined. Materials and Methods: In this experimental-laboratory study, 18 male Wistar rats divided randomly in 3 groups (control, compression, and experimental). In compression and experimental group, right sciatic nerves were highly compressed. CSF was injected in experimental group each three days. After 1 month care, all rats were cordially perused by 10% formaldehyde and their L4-L6 lumbar segments of spinal cord were sampled and with processed for histological examination, the paraffin blocks were serially cut (7mm). Slices were stained with toluidine blue and numerical densities of motoneurons in spinal ventral horn were estimated stereological (dissector) technique. Quantitative data were analyzed by T-test. Results: Significant reduce in motoneurons number of compression group (47026) in comparison with control group (173978) was seen. Also there was significant difference between compression and experimental groups (992±141) in neuron density. Conclusion: CSF intraperitoneal injection may have a beneficial effect in neural regeneration. 388 Basic Sciences Immunomodulating activity of Aloe Vera in animal model of multiple sclerosis Mosayebi Ghasem Ghazavi Ali Aghili Babak Mirshafiei Abbas 1 10 2009 12 3 109 115 11 07 2009 Abstract Background: Aloe Vera species have diverse immunomodulatory and antitumor activities. The present study was set out to define the immunomodulatory activity of Aloe Vera extract on tumor necrosis factor-alpha (TNF-α) and development of experimental autoimmune encephalomyelitis (EAE) as an animal model of multiple sclerosis (MS). Materials and Methods: In this experimental interventional study, EAE was induced by MOG35-55 peptide and complete Freund's adjuvant in C57BL/6 mice. Mice were placed in two therapeutic groups (n=8 per group) with the same age and weight. Therapy with Aloe Vera extract (120mg/kg/every day given oral) was started on day 5 before the immunization until 25 day after that. EAE control received phosphate buffer alone with same schedule. Signs of disease were recorded daily until the day 25 when mice were bled and sacrificed. Produced TNF-α by cultured spleen mononuclear cells was detected by ELISA. Results: The Aloe Vera treatment significantly reduced the clinical signs of EAE and delayed onset of disease. Mononuclear cells isolated from spleen of treated-mice with Aloe Vera showed a significant decrease in TNF-α in compared with control mice (p=0.012). Conclusion: Aloe Vera ameliorated the EAE and reduced TNF-α level in MS animal model. 299 psychology Depression symptoms prevalence, general health status and its risk factors in dormitory students of Arak universities 2008 Mohammadbeygi Abalfazl Mohammad salehi Narges Ghamari Farhad Salehi Bahman 1 10 2009 12 3 116 123 25 04 2009 Abstract Background: The University is a stressful place can cause depression symptoms and it's a critical context for studying of students’ psychological health. Because of moving away from family, living with other students, academic atmosphere pressures and uncertain future, students are often in risk of depression. This study was done to determine prevalence and related factors of depression in students of Arak, Iran. Materials and Methods: This analytical cross-sectional study was carried out on 304 undergraduate medical and basic students in Arak universities, from May to July 2008. General Health Questionnaire -28 question (GH-28) has been used for data gathering and analyzed by T-test, chi2 and logistic regression tests. Results: Mean of students' general health was 26.18±11.02 and 52.3% of students were scored above the threshold of GHQ- 28, that indicating depression. Female sex, major uninteresting, uncertain future and positive family history were the most important risk factors of depression but significant relationship between age, education Course and year were not seen. Conclusion: The prevalence of depression was higher than society and in girls is more than boys students. But there wasn’t any difference between medical and non medical students. So attention to financial and occupational future of graduated and under graduated students is essential. 552 Pediatrics Relationship between sacral ratio and primary enuresis in 5-9 year-old children Yousefi Parsa Cyrous Ali Moslehabadi Masod Haji Agha Bozorgi Mona 1 10 2009 12 3 124 130 09 12 2009 Abstract Background: Developmental anomalies in sacral bone have been recognized as one of the causes of urinary incontinence. Sacral ration was suggested as a valuable scale in determining the sacral bone health. According to insufficient studies in this field and variation in results, a determination of relationship between sacral ratio (SR) with primary enuresis were seemed imperative. Materials and Methods: In a cross sectional-analytic study, two groups (n=59) of 5-9 year-old children who admitted in pediatric and urology clinics of Amir Kabir hospital in one year were determined. Primary enuresis group with normal urine-analysis and ultrasonography, no history of dysuria, frequency, and urgency and control group without primary enuresis were selected. The mean ratio between the greatest widths of the sacral bone to its greatest length in the AP radiogram was compared between both groups. Results: In case group, 98.3% had normal SR. The mean ratio of greatest width to length was 0.89. There were not a significant relationship between gender and normal or abnormal SR. In control group, 88.1% had normal SR. The mean ratio of greatest width to length was 0.91. Girls more than boys had normal SR. Significant difference between mean ratio of SR and greatest width to length in both groups were not seen. Conclusion: Significant relationship between SR with primary enuresis in 5-9 year-old children was not seen.
