Abstract
Nowadays AIDS represents as a major problem in the world due to the lack of its cure, The best way to fight against AIDS is prevention and the way for prevention is to give health education to the people. The education proves fruitful only when it would be based on the realities of the society; and to reach this goal we have to collect the information present for the society for this purpose steps have been taken to investigate about the health information in the society. This research has been performed cross- sectionally. The data collection was based on the questionarre with multiple chocie questions (MCQ) and initially flowchart was drawn and marks were given according to the opinions of the teachers, also reliability and continuous validity was calculated in this pilot study. The sample size was composed of 1900 participants. The sampling was mulitistaged, where the first stage was stratified and the second was clustering. Statistical analysis was performed by SPSS. During the research the researchers acted upon the medical ethics. Among the cases taken into consideration 55/6% were males and 46.2% were females and the mode of age group ranged from 20 to 29 years. Also the ratio of married to unmarried was 36.2%, 63.8%. The highest marks obtained were 105 and the mean level of knowledge among the participants was 24.93(23.17-26.81). This information level did not differ too much among different groups. The unmarried cases had much more information than the married ones(p<0.0001, eta=0.49), but remarkable distinction (p<0.0001) was noted among different occupational groups. According to the results the people of Simnan & Arak held the low information level especially about the second and third levels of prevention. With respect to the wide spectrum of knowledge about prevention of AIDS in the society, the initial step is to intervence through general method telecommunication newspapers etc. and then, on the occupational basis divide them into smaller educational groups giving special education.

Abstract
Introduction: Meningitis is the inflamination of leptomeninges caused by the infectious and non infectious agents. The most common kinds of infectious meningitis include bacterial. Viral, fungal and mycobacterial meningitis. The three types of infectious meningitis are acute bacterial meningitis, aseptic meningitis and subacute to chronic meningitis which can be differentiated on the basis of CSF findings. Three fourth of the acute bacterial meningitis involve the persons below 15 years old. The etiologist cause of acute bacterial meningitis differs in various age groups. The most reliable criteria in diagnosis are laboratory and clinical findings. The permanent neurologic damages are the main complications that remain forever. Prognosis and mortality rate of meningitis depends on various factors , among which the main factors is the early diagnosis.
Methods and Cases: This is a cross-sectional study performed on 240 patients with meningitis in FIROOZABADi HOSPITAL from 1996 to 1998. Demographic information, about clinical and laboratorial findings have been collected.
Results: The male to female preponderance was 1:3. 81.3% patients had a previous history of headache, 94.4% had fever and 27.1% have defferent states of reduced alertness. 56.2% persons were diagnosed as having viral meningitis, 37% as bacterial meningitis and 6.8% as T.B. meningitis. The cases diagnosed with bacterial meningitis were influenced by the following bacteria in order: Pneumococus (44.9%), Meningococcus(26.5%), Staphylococcus aureus (12.2%), gram negative bacilli (10.3%) and Haemophilus influenza (6.1%). In 2.4% of cases CSF smear and culture were negative. The mortality rate among the patients was 8% and 8% of them developed consequences. The means of ESR duration had significant difference among various groups with different etiologies.
Discussion: In attention rate of similar studies in England and French were 24.2% and 56%. In attention to high prevalence of meningitis in our country, further greater complementary studies see to be necessary.

Abstract
Introduction: Wilms' tumor is the most common malignant and primary renal tumor in children. Studies, which have been done in some countries, have introduced numerous factors such as age of incidence, stage, lymphadenopathy, histopathology and etc. Effective in the survival rate of this tumor according to the importance of this tumor in children, we decided to perform a study about the survival rate of Wilms' tumor and the effective factors on it.
Materials and methods: This is an analytic study on 128 patients affected with Wilms' tumor whom referred to the oncology ward of Hazrat-e-Ali Asghar Hospital between 1977 and 2001. In addition to the current status of the patients, demographic characteristics, signs and symptoms, laboratory studies at the time of diagnosis and the stage of the disease were recorded and ultimately survival analysis was performed using the Kaplan-Meier procedure and life table. Cox Regression was used to determine the effective factors.
Results: The mean survival rate was 82.99 months. The number of patients was equal in both genders (64 patients in each gender) and the survival average did not have any significant statistical relationship with gender (power=%92.4). Most of the tumors were in stage 3 at the time of diagnosis. The survival of the patients was reducing significantly with the progression of the stage of tumor (P=0.002). The existence of metastasis (P=0.000, odds ratio=0.207), splenomegaly (P=0.018, odds ratio=0.336), and recurrent (P=0.037, odds ratio=0.184), were significantly reducing the survival of the patient. To determine the severity of effective factors on the survival rate of the patients Cox Regression Method was used in which, absence of metastasis and positive blood group were from well-prognosis predictive factors in these patients.
Conclusion: 5-year survival rate of the patients was 63.28% in this study. Which was lower in comparison with the results of other studies in other countries. This can be the result of delay in consulting with medical centers, the diagnosis method and or the Referral State of this center. Recent studies have shown that age and tumor size has minimal values in the prognosis of the patients due to improvement in the quality of treatment and our study support this idea. Genetic factors will probably be used in determining the survival of these patients and also in thcir treatment.

Abstract
Introduction: Sympathetic skin response (SSR) is a central, polysynaptic process which is attributed to sympathetic sudomotor activity. The descinding pathway presents spinal sympathetic system to sweat glands of hands and feets skin. The glands which are affected in reflex sympathetic dystrophy (RSD).
Materials and Methods: In present study, SSRs were recorded from left hands of 62 adult healthy subjects and 12 affected hands of RSD patients in relaxed, supine position at room temperature. Recording were performed by a pair of silver cup electrodes (1cm2) after stimulation of contralateral median nerve at volar aspect of wrist, all connected to a polygraph (physiograph, Narco, USA) to record at least five stimulation recording prosedure in each subject.
Results: Comparison of mean latency, amplitude, duraion and shape of responses in RSD 'patients with normal control group showed significant differences between duration and amplitudes (P=0.0007 and P=0.0001) while the latencies were not different and the shape of responses were mostly biphasic in both RSD and normal group.
Conclusion: Hyperactivities of SSRs in RSD patients are due to sudomotor changes of skin resistance, the SSR may also play a role in the quantitive evaluation of patients with suspected RSD.

Abstract
Introduction: stress in the natural reflection of living creatures against internal and external motivations while stress hormones are secretion through cardiovascular, every production, and security systems. Some stress producing factors are muscular activities, anesthetics, surgery, starvation, water deprivation, etc. Thus, we studied effect of prenatal water deprivation stress on hormone level and sexual dimorphic nucleus in male rats.
Materials and methods: In an experimental design, adult female and male Wistar rats (180 gr) acquired from Pastor institute and were coupled. Pregnant rats were divided randomly into control and experimental groups. Both groups were maintained under a controlled temperature (20±2°C) and photoperiod (13:11h, light: dark) conditions. Controlled group had food and water available ad lib, but experimental group had access to food and were deprived of water from the beginning of third week of pregnancy to the end of week. At 42 days at birth, male rats were slight anesthetic in order to prepare the blood and morphometric evaluations.
Results: Plasma testosterone average level in experimental group was less than controlled groups (p<0.001), while in the comparison between experimental and controlled groups, progesterone indicates significant increment (p<0.001). There is no statistically significant regarding Estradiol level between both groups. Historical study indicated that the decreased size and number of neurons of MPO and Sch nuclei were significant in experimental compared to controlled ones.
Conclusion: Prenatal water deprivation through affecting MPO and Sch nuclei, approximate inhibition of nuclei and decrease in secretion of Testosterone cause the emergence unusual sexual behavior and similar female sexual behaviors in male experimental rats in the postnatal and maturity. |

Abstract
Introduction: Good nutrition is important for growth and development of children. Regarding the fact that most of brain growth is done in first years of life, the importance of a good nutrition at this time can not be denied. In our country there is a high incidence of growth failure. Todat the complementary nutrition teaching is being performed by primary care provider and physicians are less active in this important field. In this study we investigated the effect of complementary nutrition teaching by physicians on weight of children with growth failure.
Materials and Methods: This study is a before and after clinical trial. In this study 100 children between 6-24 months old with growth failure and no disease as the result for failure were investigated. Their mothers were educated about complementary nutrition by physicians. Then children,s weight was assessed every month for three months. Results were comparisoned with the data from three months before education.
Results: In this study 45% of children were male. The mean of age was 11.38 months. There was a meaningful difference between the difference of mean weight in the end of the without teaching period and its firast (-0.49) and the difference between the mean weight in the end of the teaching period and its first (1276 gr) (p<0.001). The difference of z score at the first of teaching period (1.25) in comparison with the without teaching period (0.04) was meaningfully increased.
Conclusion: In general mothers complementary nutrition teaching by physician had an effective role in resolving childrens growth failure and improving their weight gain. We recommend that when physicians are confronted with children with growth failure it is better to perform complementary nutrition education as a priority instead of performing paraclinic studies.

Abstract
Introduction: Diabetes is one of the most prevalent diseases in the world. Today there are 100 milion diabetics around the world and in Iran it is about 1.5 milion. The prevalence of symptomatic neuropathy is 15% but with NCV it will increase to 50%. Regarding the suffer produced by neuropathy and that there is no effective treatment for that, this is necessary to investigate new treatment options. Materials and Methods: This is a clinical trial study, done during a 3 months period in vali-e-asr hospital in year 2004. 100 diabetic patients were selected randomly and divided into two equal groups. A complete sensorimotor assessment was performed and a questionnaire consisting history and clinical symptoms including limb pain, murmur and paresthesia and examinations such as pin prink test, position and vibration assessment, was completed. NCV was also done and blood sugar and HbA1c was measured. In case group 2000 micrograms vit B12 was prescribed twice weekly and in control group 10mg nortiptiline every night was prescribed. After 3 months patients were assessed again. Data was analysed using mean and standard deviation and Chi square, K-S, Leven, T and Mann Whitney tests. Results: Based on visual analage scale the difference between pain number before and after treatment was decreased 3.66 (3.66-4.25) in case and 0.48 (0.54-1.13) in control group (P<0.001). Also the difference between paresthesia number before and after treatment was decreased 2.98 (2.51-3.44) in case and 1.06 (064-1.47) in control group (P<0.001). The difference between murmur number before and after treatmat was decreased 3.48 (2.93-4.02) in case and 3.48(2.93-4.02) in control group (P<0.001). There was no significaut difference between NCV, vibration, position and pin prink test results. Conclusion: Changes in clinical symptoms in case group in comparison to those in control group was significant, but changes in physical assessment findings (pin prink, Position, vibration and NCV) was not significamt.

Abstract
Introduction: Therapeutic use of D-penicillamine is associated with several side effects. Proteinuria is the most common side effect of it, often due to membranous glomerulopathy. In this article we have reported a case of D-penicillamine induced focal segmental glomerulonephritis with systemic sclerosis. Case: In This article, we have presented a patient who had been under treatment with D-penicillamine and complicated by nephrotic range proteinuria resulting from focal segmental glomerulonephritis. Proteinuria was resolved one month after discontinuation of D-penicillamine without any additional treatment. She had no finding in favour of renal crisis of scleroderma. Conclusion: Such this pathologic form of renal involvment (FSGN) resulting from D-penicillamine has not been reported in the literature yet.

Abstract
Introduction: Bone mineral density (BMD) measured by dual energy x-ray absorbtiometry (DEXA) is widely used in management of patients with osteoporosis. Factors which are specific to machine or operator, can influence the accuracy and precision of BMD estimations. In this study we investigated the effect of leg rotation and femoral neck on densitometry of femur. Materials and Methods: In a before and after, interventional study on 200 women between 30-70 years old, without metabolic bone diseases, densitometry was done first in standard position and then in 15ْ rotation of leg from standard position and then after changing femoral neck angle from 90ه to 80ْ in relation to central femoral neck axis . Density of femoral neck, ward triangle, greater trochanter, shaft of femur and total hip was measured and data was analyzed by means comparison test. Results: External rotation of leg by 15 ه from the customary position, increased the average BMD in femoral neck, wards area, trochanter and shaft (p<0.001, p<0.04, p<0.001, p<0.008 respectively).While no significant change was observed in average BMD of total hip. Change of femoral neck area angle from 90 ه to 80 ه in relation to central femoral axis decreased BMD in femoral neck (p<0.001), and significantly increased BMD in wards triangle, trochanter, shaft and total hip (p<0.001, p<0.001, p<0.001, p<0.04 respectively). Conclusion: Malrotation of hip can be an important confounding factor when interpreting serial BMD values. Regarding the less effect of malpositioning on BMD of total hip, this area may be prefered for assessment of densitometry result.

Abstract
Introduction: Hypertension is a common asymptomatic and usually easy to treat disease. Regarding the fact that genetic, social and nutritional factors responsible for inducing hypertension are not the same in different societies, it is necessary to performe a study to introduce a model of hypertention which includes laboratory measures as risk factors of hypertension at Arak city in 2004. Materials and Methods: This is a case-control study. Study samples were 1000 persons (263 patients with hypertension and 737 healthy people). Samples were selected using multi-stage method in which the population ratio in city and village in both groups was considered. Laboratory findings and ECG results were documented. Data was analyzed using descriptive statistics and logestic regression. Results: In this study hepertensive patients were compared to healthy people. Some risk factors in this study were LVH (p<0.0001), high triglyceride, hypercholesterolemia and hyperglycemia. Also a model was made based on ECG results and laboratory findings to predict the probability of hypertension. Conclusion: By educating physicians about the determined risk factors in this study, they can control them better and decrease hypertension complications in heart, brain, kidney and eye. On the other hand the obtained model can be used in determination of the propable hypertension in people with positive family history

Abstract
Introduction: Radiotherapy after breast cancer surgery will increase local control of the disease and also increase overall survival. Radiation have some side effects on lung function. In different radiotherapy techniques, these side effects are different. Pulmonary function tests and oxygen saturation are methods for evaluation of these complications. In this study we decide to campare pulmonary complications in two radiotherapy methods. Materials and Methods: In this clinical trial study fifty one patients with breast cancer in stage II and III according to TNM staging system, which were under modified radical mastectomy in Imam Hosein hospital and refered for adjuvant radiotherapy, randomly divided in two groups. In one group patients were treated with three field technique and in others with four field technique. All patients received total dose of 48-50 Gy. For patients, pulmonary function test and pulse oxymetery were done once before initiation of radiotherapy and then one and three months after radiotherapy. Results: Measurement of FEV1 , FVC and show that no significant statistical difference was present between the two groups one month and three months after radiotherapy, also in each of the two groups the amount of FEV1 , FVC and one month after radiotherapy had no significant statistical difference in comparison to baseline tests but FEV1 and FVC after three months was decreased and had significant statistical difference respectively (p<0.001, p<0.006). SO2 had no significant defference between the two groups and also in each group after one and three month of radiotherapy. Conclusion: Locoregional radiotherapy of breast and lymph nodes areas causes a decrease in some parameter of pulmonary function tests but no difference was present between three field and four field techniques.

Abstract
Introduction: Left ventriculor hypertrephy (LVH) is one of the complicotions of systemic hypertension. LVH increases probabiltis of cardiac arrhytmia and cardiovasculer event in hypertensive patiants. In addition to hypertension other factors such as dyslipidemia, hyperglicemia and renal failure can cause LVH. This study was designed to investigate the effects of Body Mass Index (BMI) and some laboratory factors on LVH. Materials and Methods: This is a case-control study in which patients in case group (hypertensive patients with LVH) and patients in control group (hypertensive patients without LVH) were compared for BMI, dyslipidemia, hyperglycemia, and elevated Blood Urea Nitrogen (BUN) and Creatinin. Data was analyzed using Chi square test and logistic regression. Results: BMI with, high blood glucose with, high BUN and Creatinin signiticant affect in LVH presentation in hypertensive patiants. Dyslipidemia had not signiticant affect. Conclusion: In this study BMI, hyperglicemia, high BUN and Creatinin affected LVH presention in hypertensive patiant. So it is recommended that these factors be carfuly monitored and and treated.

Abstract
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: Traditionally levels of cholesterol and triglyceride are used to identify individuals at risk of coronary artery disease (CAD). The aim of this study is examining the association of ApoA1 and ApoB with severity of coronary artery disease and whether these parameters are better predictor of CAD.
Materials and methods: This is a cross- sectional study. All patients that referred to ARAK amirallmomenin hospital and enrolled for coronary angiography was entered to study. Before angiography and after gathering informed consent, levels of apoA1 apoB, cholesterol, TG, LDL, VLDL, HDL and FBS were measured. The results of coronary angiography were reviewed by two experienced cardiologist separately. Severity of coronary artery disease involvement was determined by Gensini score (GS), the data were analyzed with statistical methods by SPSS software.
Results: There is a statistically significant correlation Between apoB and GS (r=0.127, p=0.047). Logistic regression model showed that among predictors for CAD entered model eg gender, age, cholesterol, TG, HDL, LDL , VLDL, ApoA1, ApoB and ApoB/Apo- A1 ratio, only ApoB and gender were proper predictors of coronary artery Disease( CAD) (p=0.002, , p=0.001). In comparison with angiography for diagnosis of CAD, ROC analysis represent that using ApoB can be useful test (p=0.047).
Conclusion: According to result of this study, using ApoB in addition to conventional parameters for assessing the patient at risk to having CAD would be reasonable and could be an independent risk factor for CAD.
