Arterial baroreflexes are the most important mechanism of cardiovascular control. These reflexes compared with other reflexes act so rapidly that can respond to rapid blood pressure changes during daily activities. In this study we have assessed the cardiac responses of cardiac baroreflexes dynamic exercise , and compared the results with acute response during rest exercise. It was 50% of calculated maximum force. Experiments were performed on 12 young male healthy sedentary volunteers isometric exercise(protocol B) and dynamic exercise (protocol C). In order to stimulate the carotid baroreceptors neck suction device Eckberg model was used , ECG were taken continuously during experiment. In protocol A (control group) after stimulation the cardiac cycle (R-R interval) from baseline reached to acute responses in the first beat induction baseline in the forth beat P<0.003 and in the protocol C reached acute response compared with baseline in the eighth beat after induction P<0.001. If the observed acute responses during test are compared and concluded that shorting R-R interval in response to isometric due to vagal withdrawal combined with an subtle sympathetic stimulation. This phenomenon is observed more strongly in dynamic exercise.

In this report we present a care of cephalic tetanus in a 57-year old man whose onset was accompanied by right facial palsy following injuries to the face. Three days before the appearance of facial palsy, the patient have had a wound on his forhead on the same side and seven days after the injury the parient showed trismus lock jow dysonea dysphagia hoarsness and progressing generalized seizure without disturbance of consciousness as are typical in tetanus. There were no remarkable finding on brain CT or Laboratory data. He was managed as a case of tetanus in I.C.U. The patient was completely cured and he discharged on the 35th day after the onset of right facial palsy.

This research is performed to assess clastogenic capacity of cimetidine(CT) against clastogenic effect induced by benzene in terms of micronuclei. For this purpose micronuclei assay method was used. In each experimental group m 5 Balb /C mices was used. 24 hours after i. p .injections slides was prepared from bone marrow and frequency of micronuclei in polychromatic erythrocytes (PCEs) and normochromatic erythrocytes (NCEs) was obtained. Results indicated that CT at therapeutic dose (20mg/kg. b. w) can be reduce genetical damages (micronuclei) due to benzene (1010mg/Kb. B. w) with a dose- related manner (p<0.01, = -0.82). Therefore , our results indicated that CT has anticlastogenic capacity. According to above results and relatively long term use of CT, we suggest using it in the cases in which someone exposed to clastogenic agents such as benzene, especially when someone also suffer from diseases such as peptic ulcer.

The human vertebral in anatomical position have two curves thoracic and sacral with posterior curvature and two lumbar and cervical with anterior curvature. The vertebral column no lateral curves. Any curves in the both sides are called scoliosis. Presence of scoliosis is accompany with medical problems such as cardiopulmonary failure, lumbar pain asimetry and deformity. Present project is considered all of the pre-schools boys have done in ages between 11-15 years in every four educational districts of Ahwaz by school screening, 1033 cases was randomly put under. Consideration to determine the rate of scoliosis percentage measuring the length of hight, hands, feet and arm span, the relationship between theses figures and coliosis was determined, the rate of scoliosis in considering population was 1.36% in of all persons the difference who were studied between the length of hands was 5 to 12 mm. The difference between the hight and ram span with those who has scoliosis compare to normal people was considered to be more, the statistic examination was showed that the difference between the length of both hands and feet with the patients meaningful.

The aim of this study is to determining the prevalence of cigarette smoking and the causes of initiation in boy students of medical science in Arak university. Declining of smoking depends to recognizing risk factors specially in young age group and the results of this study use to evaluate the plans. This descriptive study was done with convenience sampling and studied all boy medical students in Arak university with self-administered questionaires in 77-78 curiculum. This survey instrument contained age, course of study, passed semesters, smoking bahaviour family history, praying and living site .The smoker also answered to question about time of initiation, mean of cost family information and the number who giving up the habit of smikong. 98.7% (n=475) of students with mean of age 23.06 years answered to question 34.3% had smoking bahaviour. The prevalence of smoking was the lowest among those who were married and negative family history. The prevalence of smoking in students who prayed was 1.4 of others. The most common cause of initiation were being resident with friends, stress life and initiation. Lowering we must improve the "NAMAZ" task and marriage accompaniment with lowering stress life and teaching for friend selecting and determining a suitable pattern for students in Arak university.

This study was carried out in 1994-95 and all of the under weight children in 21 villages (447 in number as case and 447 children as control with natural weight) were studied. The results showed that 49.9% of under weight children and 39.2% children with appropriate weight were infected by intestinal parasitic infection. This difference was significant (p<0.01) The amount of infection was roughly the same in boys (45.24%) and girls (44.3%) and the highest percent pf infection was seen among the 3-4 age group. The variation of parasites is more among under weight - children and more types are found among 4-5 years old children as a whole children 44/5% were infected by one or some types of parasites: Giardia lambia 25.5%, E. coli, 13.2% H. nana, 2.3% B.hominis3/55

One of the most common psychiatric disorders is depression, that sometimes may be misdiayne because of various presentations, one of these presentations is somatic complaints and patients are referred the different physicans and specialists and received symptomatic therapies. The aim of this study is the determination of prevalence of depression in patients who referred to internal clinic of Hazrat-e-Rasool-e-Akram Hospital. This study was performed between September and march of 1997. All of these patients had various somatic problems for more than two years without any organic findings them the number of patients were one hundered and the assessment was performed by SCL-90-R test. Between these patients , the score of 37 them were about of mean score. Depression was more common low admission groups and also in female. This research shows that depression is one of the best diagnoses in patients with chronic and rewirten somatic complaints which physicans did not find any organic finding in them.

This study was performed on 50 thalassemic patients in Arak city in order to assess the incidence of hearing loss among these patients. Evaluation of hearing loss in these patients were done with audiometry tests. The mean age was 10 and 40% of patients were in the range of 5-9 years old, 54% of patients were female and 46% of them were male. M/F ratio was 0.85%. 86% of patients have used Desferal (DFO) , and 14% of them have not used DFO. 14% of patients that have hearing loss, were in DFO user group. Also there is a significant relationship between hearing loss and DFO usage and between duration of DFO usage and hearing loss too. There is no significant relationship between hearing loss and ferritin level Thalassemic patients that use DFO must be assess with serial audiometry tests in order to prevent the effect of ototoxicity of Desferal.
