Using these information and Cox proportional hazard method , Kaplan-Meier method and log Rank test, the survival by sex in different subgroups of patients, was determined and compared between two sexes.   Results: Short-term 28 days survival following the occurrence of acute myocardial infarction is 90.9%. A significant difference was seen between overall women and men survival ( Respectively , 86.7% vs. 92.5% p<0.001). It decreases significantly with increasing age and increases with thrombolytic use.   Conclusion: The survival rate of acute myocardial infarction in Iranian women is less than men. Physicians should pay more attention to the treatment and care of patients at higher risk of mortality, especially women and older patients. 2118 Human Physiology The relationship between total antioxidant status with creatine phosphokinase and hydrogen peroxide in the athlete girls influenced by acute exercise training Baghaiee Behrooz Tartibian Bakhtiar Baradaran Behzad Urmia University Urmia University Tabriz University of Medical Sciences 1 5 2012 19 95 35 43 20 06 2012   Background: The research show that the relationship between antioxidant markers with inflammatory and oxidative stress markers levels changes was not clear , so the purpose of this study is investigation of relationship between total antioxidant status with creatine phosphokinase and hydrogen peroxide in the athlete girls influenced by acute exercise training   Method: This study was a semi-experimental research with a repeated measures design and 25 athlete girls within the age range of 21-24 years old volunteered to participate in the research after having expressed their consent through a consent form. Blood sample were collected in the three stages pre of GXT ( Graded exercise test) exercise test (grade: 5%, speed: 12 km/h, time: 20 minutes), immediately and 3 h after exercise test ( recovery phase ). Auto analyzer device was used for measurement of total antioxidant status, H2O2 and CPK level, also mixed model methods used for statically analysis.   Result : Total antioxidant status (TAS) concentration was faced with a significance increase after of exercise training (p≤ 0/031) (0.89 ± 0.16 ), but mixed model analysis indicated TAS levels has been reduced in 3h after exercise (p≥ 0/065) ( 0.88 ± 0.15 ). Plasma levels of hydrogen peroxide has not significantly changed after exercise (p≥ 0/255) ( 2.84 ± 1.38 ), and this increase was significant only in the recovery phase (p≤ 0/029) ( 3.04 ± 1.16 ), also CPK levels has been significance increased in both phases after exercise and recovery phase (p1≤ 0/031, p2≤0.002) ( 96 ± 18 and 90 ± 19).   Conclusion: The results of this study show that the immune system in athlete girls by increasing in antioxidants levels, can prevented the tissue injury caused from CPK H2O2 in response to acute exercise training . And Contrary to popular belief , CPK enzymes are effective role in stimulate of antioxidant response in athlete girls. 2119 Physiology The effect of aqueous Crocus sativus L. (saffron) extract on learning and memory in male streptozotocin-induced diabetic rats Kiasalari Zahra Khalili Mohsen Ghanbarian Leyla Department of Physiology, Neurophysiology and Herbal Medicine Research Center, School of Medicine Department of Physiology, Neurophysiology and Herbal Medicine Research Center, School of Medicine Shahed University 1 5 2012 19 95 44 51 20 06 2012   Background: Diabetes mellitus is accompanied with disturbances in learning, memory, and cognitive skills in the human society and experimental animals. Considering the potential anti-diabetic effect of the medicinal plant Crocus sativus (Saffron) and the augmenting effect of its consumption on the memory and mental health, this study was conducted to evaluate the effect of chronic interaperitoneal administration of Crocus.S extract on learning and memory in diabetic rats.   Methods: In this experimental study a total of 60 male rats were divided into normal and diabetic groups. Then, each of these groups was divided into three subgroups. Two of these subgroups received 30 and 60 mg/kg crocus.s extract in the treatment periods, but the third group didn’t receive any treatment. At the end of treatment period, each of these subgroups was evaluated by two ways: Y-maze (alternative behavior percentage) and shuttle box (initial latencies (IL) and step-through latencies (STL)) in passive avoidance test. Finally, obtained data were subjected to one way ANOVA test and post hoc Tokey analysis.   Results: Treatment of the diabetic animals with the extract could antagonized the augmenting effect of diabetics on initial latency (P< 0.05). Also, treatment of the diabetic rats with the extract (60 mg/kg) increased the reduced step through latency time (recall of the data) induced by diabetic in the animals (P< 0.05). However, obtained data from Y maze test show that the extract could not improved the spatial memory disruption due to diabetics.   Conclusion: Chronic Crocus.S injection is effective on the capability of maintaining information in the stores memory and reminding in the diabetic rats. However, the extract could not improve the spatial memory in the diabetic rats. 2121 Neurosurgery Endoscopic third ventriculostomy in Dandy Waker syndrome: Case report and review of literature Khoshnevisan Alireza Sistani Allah abadi Narges Abdollahzadeh Sina Tehran University of Medical Sciences Tehran University of Medical Sciences Tehran University of Medical Sciences 1 5 2012 19 95 52 56 20 06 2012   Background: Dandy walker syndrome is a kind of congenital anomaly consisting of absence of cerbellar vermis, cystic fourth ventricle and large posterior fossa. It can be associated with hydrocephaly. Generally it is treated with shunting but endoscopic third ventriculostomy can also be used.   Case presentation: Our patient is a known case of dandy walker syndrome. She has been shunted due to hydrocephaly when she was 5 months old. She was presented with signs of raised intracranial pressure and endoscopic third ventriculostomy (ETV) was considered for the patient. As ETV didn’t resolve the symptoms ventriculoperitoneal shunting was done. Patient discharged with good general condition.   Conclusion: ETV is a novel procedure for hydrocephaly, but it should be considered that there are many factors that determine the success rate of it. Correct patient selection can increase success rate of this procedure.
