Introduction: The phone's sound beams are known to be a valid test that reflects the activity of foreign hair cells, and are therefore very useful for assessing cochlear changes, such as those that occur after exposure to noise.
method: In one clinical trial, 74 volunteers aged 18-25 were examined by simple random sampling. The results of audiometric tests of the participants' pure sounds and tympanometry were within the norm on the day of the experiment. In this study, the phonetic tests of the phone were spontaneous, transient, and distorted from both ears of the subject, which was considered as a basic level of evaluation for us. Then a person's ear was selected and in the intensity of SPL 100 decibels and for 5 minutes in his ear was given a turn. After 2 minutes after the end of the presentation, the previous evaluations were repeated in both ears and the range of responses in both ears was compared.
Results: In 34 participants, submucosal nostrils led to a decrease in amplitude or SOAE responses. One of the interesting findings in this study was the emergence of new peaks in SOAE responses in the opposite ear after the presentation of the sound. The proposed noise created a significant statistical decrease in the range of TEOAE response both in the affected ear and in the opposite ear. Comparing the mean amplitude of DPOAE responses before and after exposure to shift-induced noise in the ear was significant in the Hertz range of 1699-6299, but this comparison was not significant in the opposite ear. The mean time of DPOAE incubation before and after exposure to shingles did not show a statistically significant difference in both the affected ear and the opposite ear.
Conclusion: The findings show that the phone's sound beams are a good tool for tracking hearing damage caused by noise. TEOAEs are also more sensitive to tracking than other tests, and can even be used as a very fast screening tool to assess susceptibility to hearing damage caused by noise before entering high-end industrial environments. And considered sound.

Introduction: Nowadays, depression is one of the most prevalent psychological disorders and is a prevalent mood disorder. Recently researches about depression etiology, show that in addition to different neurotransmitters and life events, internal stressors such as serum cholesterol, triglyceride and some coagulation factors can have an effect. This study was focused on the relationship between major depressive disorder and serum cholesterol level. Materials and Methods: This research is a case control study that was performed in the year 2006. Case group were 62 patients referred to Hashemi Senejani psychiatric medical center and control group were chosen from ENT ward patients of Amir-Kabir hospital. Both groups were paired match for age, gender and education. In order to determine serum cholesterol level, 5cc blood sample was taken of each person from both groups. Data was analyzed using K-S and Mann-Witheny U tests. Results: The mean age of samples was 35.5±9.9 years. 77% were female, 67.2% married, 25.8% single and 6.5% divorced. Average serum cholesterol level in case group (215.6 ± 47.6 mg/dl) in comparison to control group (183.1 ± 31.2 mg/dl) was significantly higher (p<0.05). Conclusion: Regarding the results, it seems that serum cholesterol is an internal stressor for depressive disorder so everyone with high serum cholesterol level must be evaluated for depressive disorder.

 Introduction: Experimental autoimmune encephalomyelitis (EAE) is an animal model of multiple sclerosis distinguished by infiltration of leukocytes into the central nervous system. Changes in composition and levels of unsaturated fatty acids, affect the integrity of blood-brain barrier. In this study, we evaluated the effect of Sesame oil on the leukocyte infiltration into the brain of MOG35-55 induced EAE male C57BL/6 mice. Materials and Methods: In this experimental study, male C57BL/6 mice were placed in two therapeutic groups (n=10 per group) with age and weight-matched as follow: 1.Sesame oil-treated EAE mice received 4ml/kg/day of Sesame oil given i.p. from day -3 until day +19 after disease induction, 2.Non-treated EAE mice (EAE control) received Phosphate buffer alone with same schedule. EAE was induced by immunization of mice with MOG35-55 peptide and complete Freund's adjuvant. Leukocytes infiltration into the brain was investigated 20 days after immunization. Data was analyzed using Mann-Whitney U test. Results: The results show that Sesame oil-treated mice had significantly less clinical score of EAE (2.6±0.4) than non-treated EAE induced mice (4.2±0.6), (p<0.001). Also, there was a significant difference at number of the infiltrating cells in brain between Sesame oiltreated (80±20) and non treated EAE-induced mice (150±30), (p<0.01). Conclusion: These results indicate that Sesame oil reduces infiltration of leukocytes into the brain of EAE mice, therefore lessening the histological changes and clinical signs and thus ameliorating the disease.

Introduction: Depression is one of the most common affective disorders, and in addition to different neurotransmitters and life events, various internal stressors such as blood glucose, cholesterol, triglyceride and other factors are responsible for it. Considering hyperglycemia as a possible risk factor of this disorder and inconsistency in results of previous studies, we decided to assess the relationship between different levels of HbA1C and major depression. Materials and Methods: This is a cross-sectional analythical study that is carried out on 134 samples. They were chosen randomly among patients with type2 diabetes reffering to Vali-e-Asr hospital. The patients were divided into 2 groups on the basis of their HbA1C test results patients with HbA1C less than 7% (group A), consisting 55 persons and patients with HbA1C more than 7% and equal to it (group B), including 79 persons. Participants were assessed by Hamilton scale of depression. The relation between HbA1C levels and major depression in these 2 groups was assessed using Chi square and Mann Whitney U tests. Results: We found that 40% of depressed patients had HbA1C level lower than 7% and 60% of them had HbA1C level higher than 7%. No significant correlation was found between HbA1C and major depression. But the duration of disease, using Insulin and being hypertensive simultaneously was correlated to major depression in this study. Conclusion: This study indicates that uncontrolled diabetes and high level of blood glucose is cosidered of less importance as an undelying mechanism of depression in patients with type 2 diabetes.

Introduction: Labor refers to the chain of physiologic events that allows a fetus to undertake its journey from the uterus to the outside world. Friedman (1954) describes a sigmoid pattern for labor. This study is carried out to identify the trend of labor progression in multiparous women. Materials and Methods: The present cohort study was conducted on 336 multiparous women. In order to assess labor stages, dilatation per unit of time was evaluated in each participant. Participants were divided into four groups: non intervention, induced, sedated, and both intervention groups. The related parameters were evaluated in all groups. Data was analyzed using one way analysis of variance, one sample t-test and mixed model regression models in reverse method for drawing the curve. Results: In all groups, with the increasing expansion of cervix the rate of cervix dilatation was increased. A significant relationship was observed between expansion speed rate in active phase of the first stage and the third stage, with induction of labor (p<0.05). But there was no relationship between the second stage and induction. The mean time of active phase and the second stage in this study was significantly higher than women of Freidman study (3.56 hours in contrast to 2.2 hours and 25 minute in contrast to 18 minute, respectively)(p<0.001). Also in the present study the deceleration phase was not seen. Conclusion: Now the pattern of labor progression differs from Freidman's curve in 1950 and has not the sigmoid shape, and the most important factor affecting latent phase is the dilatation of cervix at the time of admission. So determining a standard curve, without bias, is very difficult, and statistical methods should be used to decrease the effect of confounding factors of participants.

Background: Skin Sympathetic Response (SSR) is an electrophysiological technique and a central polysynaptic process. In mood disorders there are some changes in the cortex, hypothalamus activity, limbic system and basalganglia. Therefore, we compare the SSR changes in the patients with depression, mania and healthy persons. Methods and Materials: The patients with depression and mania were chosen based on DSM IV criterion by the psychiatrist. In cross-sectional analytic study, control group was selected away healthy men and women. The SSR was written by physiograph. The stimulat electrod was fixed on the middle finger of the left hand and 5 sympathetic responses were recored for every sample. The mean of amplitude, duration and latency time were computed and compared among three groups. Results: The mean of latency in control, mania and depressed groups were not statistically difference (p=.8). There were no difference between mean of duration in latency time in three groups. The mean of amplitude were not significant in three groups. Conclusion: It seems hypothalamus has not direct effect balance of sympathy skin responses.

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.

Background: Noticing the sensitivity and restlessness of medical centers, aggression in the workplace as an agitating factor is one of the dangers of medical profession that is threatening to the health and hygiene of the society. The aim of this study was to determine the types and contributing factors of aggression toward physicians and students of medicine in hospitals of Arak in 2009. Materials and Methods: This descriptive-cross-sectional study was conducted on 400 of accessible physicians and students of medicine working in hospitals of Arak in 2009. A self-made questionnaire, containing 14 questions which surveyed the status of aggressions, was used. Results: On the whole, 205 individuals returned the forms. Most of them (71.7%) had faced a form of oral, physical, or sexual aggression and had been violated by a male companion of patients. They also viewed the use of drugs or alcohol by patients or their companions, lack of security facilities, patients’ death, and lack of educational possibilities for the prevention, as influential factors in the occurrence of aggression. The majority of participants saw increasing the security personnel, presence of psychological counselors and psychologists of the ward, increasing the rest hours, decreasing the work hours of the physicians, and having a codified program for the prevention of aggression, as anti-aggression factors. Conclusion: Oral and then physical aggression toward physicians are quite prevalent. Hence, taking immediate actions and providing useful instructions for prevention are of priority in designing effective programs.

Background: Diabetes is the sixth main cause of mortality in the world, and its both types are accompanied with eye complications in a way that the risk of blindness in diabetic patients is 25 times more than normal people. Hence, this study was conducted to determine diabetic patients’ awareness of the eye complications associated with this disease. Materials and Methods: In a cross-sectional study, 200 diabetic patients referring to the eye clinic of Amir Kabir Hospital of Arak in 2008 were evaluated. Data collection was done through questionnaire and referral interviews. Then some of the factors affecting patients’ awareness of eye complications associated with diabetes were analyzed. Results: The level of awareness of eye complications associated with diabetes in 40% of the patients was average. Also, significant relationships were observed between the level of awareness and age, job, education, type of retinopathy, type of treatment, and the history of referring to ophthalmologist (p<0.001), whereas no significant relationships were observed between the level of awareness and gender, familial history of diabetes, and controlling the diet (p>0.05). Conclusion: This study showed that a higher level of awareness in diabetic patients does not necessitate that they observe a proper diet, but it can lead to patients’ greater care in preventing the development of diabetes

Background: One way of quitting addiction is forming narcotics anonymous (NA) groups. Noticing the high rate of reappearance of drug usage in these groups, the researchers decided to obtain a proper method of increasing the duration of abandonment period through the analysis of different factors affecting the reappearance of addiction. Materials and Methods: In a cross-sectional analytical study, all NA members (350 men) in Khomein were evaluated through questionnaire and referral interview. Data related to factors affecting quitting addiction, development of addiction, and reappearance of addiction were analyzed. Results: The most important causes of addiction were enjoyment and curiosity (75.1%), whereas the most important factors in abandonment were weariness and pressure from family (45.4%). Also, 48.9% of individuals had previously relapsed into using narcotic substances. The most important factors in reappearance of addiction in NA groups were unemployment and change in income (12.6%). A significant relationship was found between level of education and place of living and addiction to narcotics (p=0.000), whereas there were no significant relationships between the type of narcotic substance and quitting addiction or the mean age of individuals and trying or not trying to quit. Conclusion: Noticing the high rate of reappearance of narcotics usage in NA groups, it seems that current programs for prevention of addiction have not been successful in this regard. However, based on the findings of this study, it is suggested that provision of employment opportunities after quitting addiction can, to some extent, prevent the reappearance of addiction in NA groups.

Background: Influenza is a contagious respiratory infectious disease out breaking in cold seasons of the year. The outbreak of the new influenza A (H1N1) virus in 2009 involved large populations of the world with considerable mortality. Hemagglutinin (HA) molecule, the main surface glycoprotein of the influenza virus, is one of the key factors for serological diagnostic kits and vaccine development. Thus establishment of HA gene bank of the circulating influenza viruses is essential in gaining quick access to large amounts of protein. Materials and Methods: The first step in providing such a bank is detection and isolation of HA full genome and its subunits by using specific primers and cloning them in proper vectors. For this purpose, using standard virus genome (A/New Caledonia/20/99(H1N1)) cultured on MDCK cell, HA coding gene was proliferated by RT-PCR using specific primers. Results: Isolation and cloning of the HA gene was verified by RT-PCR, enzyme digestion and determining nucleotide synonymy. Through the use of specific cloning primers, different HA gene constructs were propagated for expression of the gene in insect cells and E.coli bacteria. Conclusion: The results indicated the complete compatibility of the extracted HA gene with the influenza (A/New Caledonia/20/99(H1N1)) hemagglutinin. It makes it possible to use the gene as a source of cloning in a variety of eukaryotic and prokaryotic expression systems
