Abstract
The treatment of supraventricular arrhythmia include wide range of medical intervention, but ideal drug for treatment of this kind of arrhythmia is yet to be developed. Pharmacological interventions due to their adverse side effects and the possibility of proarrhythmic effects are usually ineffective in treating these conditions. Herbal remedies are suitable alternatives for synthetic drugs, due to their availability, minimal side effects and lower price. Pharmacological studies and traditional medical literature point to the cardiovascular effects of the Achillea Santolina in many instances. In present study, we used isolated heart of langandrof rats as an experimental model to determine the effect of various concentrations of the methanol extract of Achillea santolina (2×10^-7, 2×10^-9, 2×10^-10 W/V) on the electrophysiological properties of the isolated heart. Results of this study show a significant depression of WBCL, AVCT and ERP and non-significant increased in time constant of recovery (trec). It may be therefore be considered a potential role for anti-arrhythmic effect of Achillea Santolina in suppression or treating supraventricular tachyarrhythmia.

Abstract
Stress responses have been excited by the painful stimuli, after induction of anesthesia and during the operation. In order to reduce these responses, it will be useful to select the type of anesthesia. Based on this fact, two groups of patients (Every group had 50 patients) were selected randomly. All patients are older than 18 years old and were chosen according to America Society of Anesthesiologist, class I, II, and were candidated for cataract surgery. Propofol were used for induction and maintenance of anesthesia In group 1 (TIVA group). In group 2 (Balance anesthesia), Sodium Thiopental induced anesthesia and the combination of N2O and Halothane were used for maintenance of anesthesia, respectively. Blood Glucose in two groups was measured before induction of anesthesia that all were in normal range (80-120 mg/d). Then after induction, incision and 30 minutes after start of surgery, blood Glucose was measured again and deviation from basal level were classified in three categories as: <10%, 10-20%, >20%. The results demonstrated meaningful difference between two groups, statistically (Chi-square, P<0.001). Increasing the blood Glucose in group 2, in three stages, was more than group 1. Blood Glucose level was increased about 20% from its basal level, in the majority of group 2 (32% after induction, 64% after incision, 62% 30 minutes after start of surgery). But, this amount of increasing in group 1 was detected as follow. 16% after induction, 16% after incision, 12% 30 minutes after start of surgery. It is possible that in TIVA group’s, control of blood Glucose and stress responses better than balance anesthesia group’s. The comparative measurements of catecholamine level in both groups would be the next investigations.

Abstract
This study has been performed on show the incidence of sensory neural hearing loss (SNHL) in patients with chronic Otitis Media (COM) and it’s different parameters. 207 patients with persistent or previous otorrhea have been examined. 70 patients had bilateral otorrhea and 137 patients had unilateral problem so overall 277 ears are evaluated. The BC greater than 15 dB without carhartnotch was the basis for diagnosis of SNHL. 66 patients had SNHL and of them 26 cases were bilateral so total number of ears with SNHL were 92 (The incidence of SNHL was 32.2%). 3 cases were due to other causes like TB (1 case) RM fistula (1 case) and squamous cell carcinoma (SCC) of middle ear (1 case). About 90.3% of cases had down slooping high frequency SNHL in their audiogram. In 47.6% of the ears with granulation tissue and cholesteatoma had SNHL while 28.7% of cases with chronic perforation revealed SNHL. Analysis of this study showed that there is a probability of increased SNHL during old ages the cases of prolonged and persisted otorrhea also revealed a higher incidence of SNHL. We didn’t disclose correlation between age and severity of SNHL.

Abstract
Breast cancer is the most common cancer in women. Histologic grading is one of the prognostic factors in breast cancer. The present study performed in analytic descriptive method and based on the slide review of beast biopsies received in the pathology department of 5th Azar Hospital from 1976 to 1978, and on the basis of Bloom-Richardson criteria (Mitoses, tubule formation and nuclear pleomorphism). The results are consist of: 1) Infiltrating duct carcinoma is the most common histopathologic form, and tubular carcinoma is the least common 2) The most common age is 36-45 years 3) There is meaningful relationship between mitoses and tubule formation and between pleomorphism and tubule formation. But there is no relation between nuclear pleomorphism and tubule formation in the tumor. Histologic grading of breast carcinoma should be reported by pathologist for clear determination of prognosis and also the best choice for management of the tumors.

Abstract
Intestinal parasites have worldwide prevalence and is considered to be as one of the most important hygienic problems in the world. As a whole, we can say there is no where in the world without parasites infestations. For the assessment of parasitic infestations of children under 2 years old in urban areas of Semnan, sample of stools for 3 consecutive days of 359 children under 2 years old, whom were accompanied by their mothers to the health center, were obtained. Samples were recognized by Formalin/ether and direct methods and thionin staining. From 359 children below 2 years old that their stools were examined, 14.2% of them had Protozoa infestation and Giardia Lamblia by 10% was the most common parasite. In these children, infestation by intestinal helminths was not seen and infestation by pathogen parasites was seen in 10.3%. There was significant association between the age and infestation by intestinal parasites (P=0.0000). There was not any significant association between the sexual, areas condition (Tropical/cold) by intestinal parasites. The most common parasite was Giardia. Therefore, educating mothers the principles of hygiene, can prevent infestation to parasites and the potential complications.

Abstract
Low birth weight (LBW) is the main known determinant mortality in under 1 year old children particularly in neonates. The aim of this research is to study the rate of LBW and evaluation of some effective factors in LBW, such as: Difference races, residential conditions, maternal age, parity. This research is analytic-descriptive and cross-sectional study. The study population consists of 2183 newborns that are given birth in Dezyani Hospital during 1996. These samples were chosen by systemic randomized technic (3:1). Information was gathered by a questionnaire. The findings show that LBW rate was 6.3% in population under study, which in male and female newborns were 5.7% and 6.9% respectively. The LBW rates in newborns with mothers age?18 years old and those with ?35 years were 1.8% and 1.4% folds higher than LBW rates for newborns with mothers age 19-35 years. The LBW percentage for primiparous women were 1.9 folds to multiparous who had 2-4 deliveries. LBW rates for newborns with Systanie race were approximately 1.8 folds higher than newborns with Torkman ethnic. The results of this study indicate factors such as: Maternal age, race, parity, affect on LBW rates.

Abstract
Serological Widal test is a fast, reliable and easy to perform and this test still is a suitable diagnostic method for diagnosing of typhoidal disease in many clinical laboratories. However, there are some doubtful reports regarding diagnostic value and credibility of this test, which was a motivation for present research. In this study, a total of 378 patients in two groups including 182 typhoidal patients with positive culture for Salmonella Typhi and para-Typhi A, B, C and 196 non-typhoidal febrile patients with negative culture for Salmonella, were studied in Hamadan city during 1994-97. All patients had at least one Widal test. In first group, 52.7% of patients have a titer of ?1:40 using anti-O (A, B, D) and 42.3% of patients also have a titer of ?1:80 using anti-O (A, B, D). In second group, 7.2% of patients have a titer of ?1:40 and 5.6% of them have a titer of ?1:80. In first group, 66.4% of patients had positive blood culture for S.typhi, however, 31.3% of them had positive antibody for OD titer. The results of this study indicated that sensitivity of Widal test for titer of ?1:80 was 86%, specificity 64% and PPV 42% and NPV 95%, therefore the negative Widal test did not have significant effect on the clinical diagnosis of typhoid disease.

Abstract
Enuresis is one of the most common and complex problems of childhood and it affects the relationships between children, parents and coevals. It negatively affects these relationships. Studies have shown that in comparison with normal children, Enuresis children have behavioral problems and suffer them. This survey was done with this aim to determined and compare enuresis and non-enuresis children’s behavioral adjustment in Hamadan primary schools. This study was conducted by case-control method and a total of 320 pupils were studied. These subjects were selected randomly by multi-phase sampling. The interview forms were the data collecting means. It was based on children’s behavioral checklist for the school-aged children which had been reported by Russel and Cassel. The survey results showed that there was a difference in scores obtained by enuresis and non-enuresis children from the view point of self, social, physical, home and school and general personality adjustment and high percentage enuresis children had behavioral problems and there was statistical meaningful difference between the scores obtained by two groups.

Abstract
Diarrhea and malnutrition are important health problems in human societies, especially in developing countries, leading to a huge number of deaths annually. Numerous studies have death with the relationship between malnutrition as a predisposing factor and acute diarrhea, but they have yielded conflicted results. In a cross-sectional controlled study, we examined 398 infants 1-24 month-old referred to the diarrhea-training unit (DTU) of hospital. After treating dehydration, height, weight were measured and compared with an age-matched control group. In cases with acute diarrhea, 3.2% had severe, 14.8% had moderate, 48.8% had light malnutrition, 33.2% had no malnutrition according to Gomez scale. In the control group, the percentage of subjects with severe, moderate, light, and with out malnutrition were 0.5%, 2.2%, 32.4%, and 64.8%, respectively. Average weight for age and weight for height scores were significantly lower in cases with acute diarrhea than in control subjects. However, average for age score was not statistically different in the 2 groups. Patients with acute diarrhea suffered a higher prevalence of malnutrition compared with those from the control group. There was not statistically significant relationship between growth indices and socioeconomic class of the family. A lower percentage of infants with acute diarrhea compared with control group enjoyed breast-feeding as the primary feeding routine. The period of breast-feeding was shorter in infants with acute diarrhea. Nevertheless, breast-feeding neither have significant effects on malnutrition nor on weight and height growth indices. Overall, we concluded that malnutrition and decreased weight growth index might be important predisposing factors for acute diarrhea. Early diagnosis and treatment of malnutrition (Especially moderate and light degrees) are very important measures to be taken in order to decrease diarrhea and its complications.

Abstract
The word human population has been terrified nay AIDS. The barbers are persons that work with sharp tools. If their instruments become infected, they can transmit the infection to others. Therefore, the purpose of this study is to determine the barber’s knowledge, attitude and performance about AIDS prevention. This project is a descriptive study on 150 selected barbers. The methodology of research was a set up questionnaires, that have been completed by the barbers. The results showed that, their knowledge, performance about the AIDS are moderate (50%, 48.43%) and their attitude are weak. Performance among men and women is significant (P?0.02) in addition correlation between knowledge and attitude, attitude and performance are significant, according to the duration of working as barber (P?0.01). In general knowledge, attitude and performance among barbers are weak, therefore it is suggested that health and hygienic official teach the barbers how to behave in this regard.

Abstract
Gardenerlla Vaginalis is a tiny pleomorphic gram negative mostly isolated from secretions of females with bacteria vaginosis. The organism cause infections such as endometritis, salpingitis, urethritis and in pregnant women cause the delivery of low-birth weight babies with less than 2500 grams. This study was done as a descriptive study on 200 pregnant and non-pregnant women in 2 groups, referred to gynecology and obstetric ward of Babol University of Medical Sciences. We gathered information by questionnaires then clinical examination and sampling from posterior fornix was obtained. PH values of the samples were determined, wiff test, wet mount examination and gram staining were practiced and finally the isolated bacteria from media such as HBT, PSDA, etc were examined by proper microbiologic tests to confirm the diagnosis. In this study 24% of non-pregnant and 14% of pregnant women found to be infected with GV. In 30.7% of infected women the rate of colonization of GV was high. However detection of bacterial vaginosis by clinical diagnosis has shown an incidence of 41% in non-pregnant women and 27% in pregnant women. Meanwhile 60% of non-pregnant females had positive pop-smears for GV. It should also be noted that the rate of GV infections has found to be higher during the first trimester than the second or third. Samples from patients with bacterial vaginosis show an associated increase in the number of gram negative of variable gram reaction bacilli with a decrease in the number of lactobacilli. Thus, diagnosis of bacterial vaginosis is preferably recommended to be made using simple methods such as wet mount examination and gram-staining of vaginal discharges.

Abstract
Diabetes commonly is associated with CAD risk factors, in addition sub-optimal metabolic control of diabetes is associated with increased incidence of thyroid function disorders. In this study patients with diabetes type II who were referred to 5th Azar Hospital in Gorgan were assessed to find out the relationship between thyroid dysfunction and NIDDM in such patients in Gorgan. We studied 210 diabetic patients in hospital outpatient department. The blood pressure, height, weight, serum total Cholesterol, Triglycerides, fasting blood sugar, and glycosylated hemoglobin (HbA1c) were determined. The obesity (BMI>30) were seen in 35% of the subjects. Hypertension and hyperlipidemia were seen in 38 and 65 of our patients respectively. The observed disorders included goiter (30%), sub-clinical hypothyroidism (13%), clinical hypothyroidism (4%), and clinical hyperthyroidism (0.5%). The patients were divided into two groups according to HbA1c: Group 1 with HbA1c<8 and group II with HbA1c?8. A significant difference was observed in TSH serum concentration between group I and II (1.5±1.2 vs. 3.7±11.3 mu/l, P<0.05), whereas the concentration of T4 (10±11 vs. 11±8) and T3 (2.4±3.7 vs. 1.9±3.2) were not significantly different between the two groups. The mean concentration of HbA1c in patients with hypothyroidism was significantly higher than those that of non-hypothyroid subjects (11±2.5 vs. 9±2.5, P<0.005). A significant positive correlation was observed between HbA1c concentration and TSH levels (R=0.2, P<0.01). Our results confirm the association between thyroid dysfunction and uncontrolled diabetes mellitus. It has been recommended that the final diagnosis of thyroid function disorder in diabetic patients should be made after optimal metabolic status has been archived.

Abstract
Structurally diverse groups of compounds are known to be effective as Calcium antagonists. The most potent class of antagonists comprises derivatives of 1, 4 Dihydropyridine of which the most widely known agent is Nifedipine. This class of compounds has been subject of many structure-activity relationship studies. In this research we evaluated the Calcium channel antagonists activity of various diester analogues of Nifedipine on rat ileal smooth muscle. In these analogues, the Orthophenyl group at position 4 is replaced by 1 Methyl-2-Meythlusulfonyl or Methylthio-5 Imidazolyl. Wistar rats (180-250 g) were killed by a blow to the head. The intestine was removed above the ileocecal junction and longitudinal smooth muscle segments of 2 cm length were maintained at 37°C in a 10 ml jacket organ bath containing oxygenated intestinal Krbps solution. The contraction were recorded with a forced displacement transducer connected to a physiograph. The contraction was elicited with 80 mmol kcl. Test compounds were cumulatively added to produce 50% relaxation of contracted ileal smooth muscle (IC50) that was determined from the concentration response trace recorded by physiograph. The comparison of activities of symmetrical esters indicates that increasing the length of methylen chain in C3 and C5 esters substituent decreased the activity and comparison of activities of a symmetrical ester, compound indicate when at C3 was a small substituent, increasing the length of methylen chain increase activity.

Abstract
One of the effective way to treat and control the neuromuscular organs from injuries of lower limbs in the exercise of backward running. The present research has been set up to determine the effectiveness of this sport and comparing it with forward walking. The aim of this clinical trial is to differentiate between the effectiveness of these two sports on the functional performance tests of lower limbs. To carry out this study 30 normal male has been divided in two groups, in group one forward walking is carried out three 15 minutes session per week for six weeks, and backwards walking has been arranged for group 2 on the same condition. The functional performance tests in this study were vertical jump, single leg hop jump for the distance of 6 meters, in forward and backward running. The findings from this study indicate that there is not meaningful improvement during the six weeks within the 2 different sports. On the basis of these results the 2 procedures of running forward and backward have got the same effect on the increasing the functional performance of lower limbs and both sports can be used active functional rehabilitation.

Abstract
Diabetes mellitus is a common metabolic disorder that is associated with long-term complications of various organs, such as cardiovascular system. This study is about evaluation of myocardial function and determination of related cardiovascular factor in type 2 diabetic patients who referred to diabetes clinic of 5th Azar Hospital from 200 patients who referred to the clinic, 48.5% had diastolic and 29.5% had systolic dysfunction. Related factors with both diastolic and systolic dysfunction of diabetic patients are: HbA1c level (Control of diabetes), duration of diabetes and hypertension. This investigation shows that: Incidence and severity of systolic and diastolic dysfunction in type 2 diabetic patients are related to metabolic state and quality of diabetic control. Incidence of hypertension increase in diabetic patients, and hypertension is an important risk factor in diastolic and systolic dysfunction. Diastolic dysfunction is more common than systolic dysfunction in diabetic patients. Intensive control of blood Glucose level lead to decreasing the incidence of coronary artery disease in diabetic patients. We suggest, intensive control of blood Glucose level, treatment of hypertension, regular cardiovascular evaluation in diabetic patients and screening test for early diagnosis of diabetes in high-risk population should be taken under consideration.

Abstract
Due to importance of menopause and it’s effects on the menopausal women, and also the use of hormonal replacement therapy, we decided to evaluate side effects of Estrogen therapy on menopausal women, such as sleep disorder and related problems. 60 menopausal women entered a 3-months prospective, placebo-case controlled, double blind and accidental study. They were selected after taking history and physical examination, some necessary laboratory data, exclusion of interfering factors. They were divided in 2 groups with equal members. Conjugated Estrogen (0.625 mg per day) was given orally for 3 months to case group. Placebo (1 tablet per day) was given to control group. The 2 groups evaluated again after 3 months. A questionnaire with 7 questions was given to the members of 2 groups before and after treatment. Treatment with Estrogen reduce number of sleep awakening, daily drawsiness, morning tiredness and improve the sleeping and resleeping (P<0.05) and with confidence interval of (95%). In our study, there was not significant correlation between weight, age, duration of menopause, cause of menopause with sleep disorders. According to this study, we conclude that Estrogen replacement therapy reduce sleep disorders in post menopausal women. These findings confirm HRT benefits.

Abstract
The cancer of breast is the most common malignancy among women and after cancer of the lung is the second cause of death in females. Thus, early diagnosis and treatment can have a effect significant in prognosis and clinical course of disease. One of the numerous controversial tissues to the clinical management of breast cancers is the role of fine-needle aspiration (FNA) to assess the accuracy and determine the role of FNA in breast cancer diagnosis, we performed both FNA and excisional biopsy in 86 unselected patients with palpable breast masses and correlated the cytologic and histopathologic findings. In our study, FNA had no false-negative and no false-positive results, and the sensitivity of diagnosis of malignant tumors was 88.8%, the specificity of diagnosis of benign lesions was 96.2% and the predictive values were 100%, respectively. On the basis of above study, breast FNA may add a measure of confidence in the diagnosis of benign lesions, provides a safeguard for preventing misdiagnosis of malignant lesion, and might expedite and reduce the cost of managing breast cancer. Also, breast FNA like any diagnostic method depends to individual techniques and continual practice.

Abstract
Streptococcal pharyngitis and rheumatic fever/rheumatic heart disease are among the major public health problems in children. In this study we assay the frequency of group A Beta hemolytic Streptococcus in nasopharynex of 1588 healthy 6-12 years children in Gorgan in north of Iran. The sample obtained during February to March 1998, using sterile soap. The prevalence of this bacteria were 11% (175 strains) the rate of colonization in girls and boys were 10.8 and 11.2% respectively. Our study shows that the carrier of this bacteria in Town’s school children are more than the villages.
