Introduction: The off response of baroreflex is mostly ignored by recent studies. In the present study we aimed at assessing this during rest, and isometric and dynamic exercise.Material and Methods: 12 young male subjects volunteered the study. Using an Eckbergs neck suction device each subject received a brief (10 sec.) about of sustained stimulus with - 50 mm Hg pressure in the neck chamber. The workload incorporated was 100W for dynamic and 50% of maximal effort for isometric exercise. Electrocardiogram was recorded on line R-R intervals were assessed beat and responsed cardiac response. This was significant at all three states. Results: On the average, the peak off- response tachycardia occurred earlier (3rd sec.) in exercise tests as compared with that of rest (5th sec.). The intensity of tachycardia was more prominent at rest, isometric exercise, and dynamic exercise, respectively, and the difference between rest and dynamic exercise gained significance (p<0.01). Conclusions: The attenuation of so called post vagal tachycardia during exercise is in accordance with the assumed reduction of vagal tone during exercise.

Introduction: Alimentary parasitic infections are still one of the main problems in developing countries, and their relation with environmental factors is important. Since children are more vulnerable to these infections, in basic researches this group is more targeted. Material and Methods: This descriptive - analytical cross - sectional study was carried out on 1-13 Years children who were living in Shahrak-e-Valiasr Arak. Simple random sampling was used for selecting 385 children. Three days collected feces samples from each person were examined using Formaline - Ether concentration technique. Data were analysed by Chi square method.Results: The results showed a prevalence of 42.3% of intestinal parasitic infections in the children. From these, 17.4% were pathogen parasits. The highest prevalence was reported for Giardia lamblia (16.6%). Girls were more infected than boys. The level of infection was significantly increased by age. The prevalence of the infection was more in orphans or in children who had uneducated parents.Conclusions: Since date indicated of a high prevalence of intestinal parasitic infections in the children, it is suggested to use washed and clean vegetables and fruits and also emphasize on personal and environmental hygiene.

Introduction: The purpose of this research is to examine depression rate in nursing, midwifery and health students and its relation with individual perception about being religious in Hormozgan University of Medical Sciences and Health Services.Material and Methods: In this study 299 students (105 male and 194 female) were examined with non-random and easy sampling method. They examine with Beck Depression Test and Alport Religious Guidance. Results: On the basis of Beck Depression Test 55.5% were without depression, 32.1% mild depression, 11% moderate depression and 1.3% sever and very sever depression. Also with use of two dimensions Alport Religious Guidance, 8.7% of subjects had external and 91.3% internal religion. On the basis of other classification of Alport Religious Guidance 70.9% of subjects had high, 21.4% moderate, and 7.7% low religion. By the means of X2 Test it shows the rate of depression between girls and boys have not significant difference (p>0.05). In order to access relationship between the rate of depression and religious viewpoint, Pearson Correlation Test was used that results show that it is reverse correlation between them. So that with increased religious viewpoint the rate of depression was decreased (r=-0.16 , p<0.05).Conclusions: In low religion subjects, the rate of depression was more than religion subjects.

Introduction: Rubella is a self limited viral disease. But in pregnant woman it can produce congenital rubella syndrome with multiple fetal defects. Mother's immunity is made by the disease or vaccination. In advanced countries, vaccination against rubella is done by government. However, in Iran rubellas vaccination is not recommended for all by health organizations. This study is done for the determination of immunity against rubella in women before marriage.material and Methods: In this study, women referring to medical lab for screening of thallassemia are selected as the subjects of the research, the blood of the subjects was analyzed to check their immunity for rubella by the use of ELISA (Radim kit), their rubellas immunity was determined. In this study 1563 samples were under investigation, the research was in the form of descriptive study and sampling was done simple randomly. Results: In this study among 1563 samples, 80.2% (1256 samples) were immune against rubella and among 19.8% (309 samples) were sensitive for rubella. As a result there was a positive significant relationship between age and immunity (p= 0.00058). But there was not a significant relationship between level of education, place of living and immunity.Conclusions: Considering the results of this study it is concluded that vaccinotion against rubello in childhood can be useful, and has a positive effect against rubella. If there is finitial limitation for this vaccination it is recommended for high school girls.

Introduction: Continuing medical education of physician society as a part of human power education is specially important. For change in methods of behavior, reasoning and professional culture so study the level of physicians motivation in them for entering in programs in necessary.Material and Methods: To determine relation of 7 criteria: as motivation factors consist of convenience, relevance, individualization, self-assessment, interest, speculation and systematic has been the object of this research. For gathering data has been a questionnaire with 26 question that into reliability determined 0.68 sample capacity has been 360 province in Markazi Province that and analyzed by Chi2 Test and software of spss.Results: This research showed a meaningful relation between all of the criteria and establish motivation in prysicians (p<0.0001). Coefficient of correlation has been 0.846 in individualization, 0.809 in convenience, 0.605 in relevance, 0.523 in speculation, 0.509 in systematic, 0.491 in self-assessment, 0.483 in creation of interest. Conclusions: This research showed that creation of motivation will be more if physician given partnership and express their opinion programs and time and place of program be more suitable.

Introduction: Neisseria gonorrhoeae is a gram negative diplococci belong to family neisseriacae and is causative agent of gonorrheae. Culture and antibiograme of these bacteria is done lower than other cases and determination rate of MIC in these bacteria is only done in reference laboratories. The goal of this study is introducing a relationship which in studied population, MIC more easily and without doing complex technical examinations is placed available for physicians. Material and Methods: In this research on 50 cases of Neisseria gonorrhoeae isolated from patients with gonorrhoeae antibiograme test were done and then for every antibiotic discs the zone of inhibition were measured. Then on the basis of instructions of NCCL for four antibiotics were planed to this disease (penicillin, tetracycline, spectinomycine and ceftriaxone) MIC on GC agar medium were measured and between zone of inhibition as an independent variable and MIC as a dependent variable linear regression is seen which from this line equation can understand how is the relation between MIC and zone of inhibition. It means that wether this relationship is direct or reverses?Results: The findings show that in all antibiotics the relationship between zone of inhibition and MIC are negative (reverse) and regression coefient for first three antibiotics have p<0.0001 and for fourth antibiotic has p<0.001.Conclusions: It means that with probability less than 0.0001 for penicillin, tetracycline, spcctinomycine and probability less than 0.001 for ceftriaxone can estimate the counter effect of zone of inhibition and MIC in studied population.

Introduction: Lower gastrointestinal bleeding (GIB), as well as upper GIB, is one of the most common causes of patient's referral to surgen and internist. From patients view, nothing is as terrible as bleeding from mouth or anus. Lower GIB may be benign or malignant, simple or complex. Bleeding may be occult with further weakness, or it may be severe and lead to death. So lower GIB work up from etiological point of view is mandatory. Material and Methods: This was an observational and descriptive-analytic study, performed from Jul, 23, 2000 to Aug, 11, 2001. In this study, we evaluated patients with gross rectorrhagia referred to especial clinics, by history taking, physical examination, anoscopy, rectosigmoidoscopy, colonoscopy and barium enema. Results: From the total number of 580 cases who completed the study, 55.2% were male and 44.8% female. 40.3% had constipation and rectorrhagia, 14.7% had chronic diarrhea with rectorrhagia and 45% had rectorrhagia with normal bowel habits. From etiological point of view, 20% of patients had hemorrhoid, 12.4% had anal fissures, 10.2% had inflammatory bowel disease (IBD), 9.65% had polyps, 3.1% had infective proctitis and 30.4% were unknown causes.Conclusions: Gross rectorrhagia is relatively common cause of GIB. Although most of the lesions were of benign nature, in this study, because of serious complications and high morbidity and mortality, IBD, colonic polyps and cancer must be ruled out with complet work up.

Introduction: Asthma is one of the most chronic long diseases of childhood that caused repeated admitting in hospital & school day lost. Asthma identified with recurrent attack of cough, dyspnea & wheezing. The goals of treatment are relief of Acute symptoms, prevention or diminish the frequency of recurrent symptoms maintain normal pulmonry functions & maintain normal activity level.Material and Methods: In our Study, all patients with final diagnosis of asthma that hospitalized in Amir-Kabir hospital from 79.1.1 to 80.1.30 evaluated.Results: first line drugs that used Aminophylline (62%), antibiotics 56%, corticosteroid 42%, Inhaled salbutamol 14% and oral salbutamol 0.6%. Others drugs that used in the period of treatment according to prevalence are Antibiotics 85%, aminopylline 74%, corticosteroid 5%, oral salbutamol 40%, Adrenaline 31%, inhaled salbutamol 24% & theophylline - G 14%. Most of clinicians use Aminophylline in stead of beta Agonist, only 14% patients receive inhaled salbutamol in the first line. Conclusions: There findings reflect inappropriate therapy of asthma, It seems that little knowledge of clinicians about new medical methods, absence of new drugs and little knowledge of patients & their family of patients and their norriment about use of inhaled drug, are basic problems. That's logical, that education of clinicians & patient their parents, explanation the mandatory of preparation of new drugs & proper device to manages can resolve there problems.
