In this research we examined the sensitivity of micronucleus assay for monitoring clastogenic effects of low dose fast neutrons. Syrian mice (12 weeks old) were irradiated by fast neutrons emitted from a 241Am-9Be source. The absorbed dose was 1.5, 2.25, 3.375 and 5.06 cGy. Mice were scarified by cervical dislocation at different post irradiation times (24, 48 and 72 h). The results obtained show that the frequency of neutron-induced micronuclei in polychromatic erythrocytes (PCES) is significantly higher than those of control groups (P<0.05) at neutron dose used in this experiment. We concluded that micronucleus assay is an effective and also inexpensive method for monitoring clastogenic effects of high LET radiation in low dose levels.

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.

Background & Objective: It has been reported that, the ?-Carboline alkaloids of peganum harmala seeds have a stimulatory action on Serotonin and Catecholamines release in different brain regions. In addition, one of the most important pharmacological effects demonstrated for ?-Carboline is a revesible inhibitory action on MAO-A. These findings suggests that ?-Carboline, should alleviate at least some of the signs of depression. The purpose of present study is to determine the anti-depressant activity of ?-Carboline Harmane, Norharmane and Harmine. Materials & Methods: All experiments were carried out on male Swiss-Webster mice (25-30 g). The anti-depressant activities of the ?-Carboline were assessed using the forced swim test. This test is the most widely used tool for anti-depressant activity preclinically. In this test, mice were placed into a cylindrical glass (25 cm height, 12 cm in diameter) containing a column of 15 cm of water at 25±1°C. After 30 min of the ?-Carboline injections, the mice were subjected to forced swimming test for 8 min and their immobility time was recorded. Results: Interperitoneal (IP) injections of Harmane (5-15 mg/kg), Norharmane (2.5-10 mg/kg) and Harmine (5-15 mg/kg) significantly decreased the immobility time in the mouse forced swim test. The inhibitory effects of Harmane, Norharmane and Harmine were antagonized by Flumazenil (5 mg/kg, IP) but not by Reserpine (5 mg/kg, IP, 18 h before test). Conclusion: The results suggest that the anti-depressant activities of Harmane, Norharmane and Harmine may be mediated through an inverse agonistic mechanism.

Background&Objective: Copper and zinc, two essential trace elements, are neuroactive substances that can be synaptically released during neuronal activity. These metals have been implicated in diseases with neuropathological components, including Alzheimer's disease, Menkes disease, Wilson's disease, Pick's disease, stroke and seizures. Copper and zinc levels in body tissues reflect many physiological and pathological conditions, including dietary factors, hepatic disease, and acute and chronic infections. The purpose of the present study was to examine the plasma levels of copper (Cu) and zinc (Zn) in schizophrenic patients and to compare the Cu/Zn ratios with that of matched healthy subjects. Materials&Methods: Forty patients with schizophrenia (diagnosis were made according to DSM-IV) were sampled along with 50 healthy controls. Exclusion criteria included another concurrent psychiatric disorder, pregnancy, and medical disorders (endocrine, immune, liver cirrhosis, renal) or drugs (anticonvulsants, contraceptives, glucocorticoids) known to affect trace element metabolism. Fasting blood samples were withdrawn from an antecubital vein between 07.00 and 09.00 h. Plasma copper and zinc levels were measured using an atomic absorption spectrophotometer (Perkin Elmer GmbH, Uebelingen, Germany). Two-tailed t test was used to determine statistical differences. All data were analyzed with the computer program, GRAPHPAD software (V2.01+). Results: Mean±SE of sera copper levels in cases and controls were 145±28 and 65±3 µg/dl respectively (P<0.05). Also Mean±SE of sera zinc level in cases and controls were 67±2 and 81±4 µg/dl, respectively (P<0.05). Cu/Zn ratios was 2.07±0.38 and 0.87±0.04 in cases and controls respectively (P<0.05). Conclusion: There was a significant higher Cu/Zn ratio in schizophrenic patients compared to healthy subjects. These results suggest that Cu and Zn may be involved in the pathophysiology of schizophrenia.

Background&Objective: Thalassemia is an inherited and chronic hemolytic disorder. Like other diseases it can make psychological, social and financial problems for both patients and families. The necessity of this research is to teach the way of treating the psychosocial problems of this illness and to increase the quality of patients and families life. It is also a descriptive study to examine psychosocial and financial disorders and coping strategies among families with patients suffering major beta thalassemia Materials&Methods: 320 parents (229 of mothers and 91 of fathers) were included in this study. These families were those who were visited clinics associated with Gorgan's University. Data collection was done using a self structured questionnaire as well as Mc Cubin and Thompson scale for identifying coping strategies. Results: Findings revealed many problems, such as: stress for disease (82.8%) and the patients' vague future (81.8%). The mentioned problems were of psychological disorders. And about social problems: 33.8% of patients families were deprived of having picnics in their free times and helping the patient meddles the routine work of homes in 30.1% of families. The financial problems: the cost of traveling and providing the medicine (63.8%). In addition 97.5% of families had faith and reliance in God in order to help them and to believe their child's illness as a reality. It is apparent that families use different kinds of method in order to cope with psychological, social and financial problems and to face the disease. Conclusion: Most of families have a strong belief in religion and as a result they believe that any kind of problems and especially disease is one of ways to reach God. This is the idea which helps them to face this disease stoutly.

Background & Objective: Bone densitometry is an appropriate method for the evaluation of the patients’ skeletal status. This study was done to determine, the relationship between MI (Mental Index) of mandibular bone in panoramic radiography and skeletal status in femoral neck and lumbar vertebrae (L2-L4) in women referring to the radiology department.

Materials & Methods: In this cross sectional descriptive study, the panoramic radiographs of 67 healthy women over 35 years old referring to radiology department Mashhad, Iran during 2004, were assessed and their MIs recorded. All of the patients were then referred to Toos Bone Densitometry Center, for bone densitometry in left femoral neck and lumbar vertebrae (L2-L4), using DEXA technique with Osteocore apparatus. The patients were divided into three categories of normal, osteopenic and osteoporotic in each skeletal region according to their T-score. The data were analyzed using ANOVA and Pearson's correlation coefficient.

Results: The mean of Mental Index between normal and osteopenic subgroups of skeletal status in femoral neck showed a significant difference (P=0.042). The mean of Mental Index between normal and osteoporotic and osteopenic and osteoporotic subgroups of skeletal status in lumbar spine region showed a significant differences (P=0.02 & 0.05, respectively). The Mental Index was significantly related to T-scores in femoral neck and L2-L4 regions (r = 0.33 & 0.32, respectively, P<0.01).

Conclusion: This study showed that using Mental Index of mandibular bone can be useful for estimating skeletal status of patients but is not enough for precise evaluation of skeletal status of patients.

Background & Objective: Many evidence indicated that action of glucocorticoid receptors can modulate anxiety behaviors and these effects probably mediated by nitric oxide (NO) system. Thus, in this study, we investigated interaction between corticosterone and NO on anxiety behaviors in mice in elevated plus maze (EPM).

Materials & Methods: In this experimental study male albino mice (25-30 g) were used. A standard EPM was used to determine anxiety behaviors. Two behavioral measures were used that include of the percentage of time spent in the open arms and the ratio of open arm entries to total entries during 5 min. Animals received IP injection of L-Name 30 mg/kg as an inhibitor or L-Arginine 50 mg/kg as a synthesis of NO or saline 60 min and corticosterone (1, 2.5, 5 mg/kg) 30 min before of evaluation.

Results: Analysis of data indicated that corticosterone at doses of 1 and 2.5, but not 5 mg/kg significantly reduced anxiety behavior in mice (P<0.05). Also pretreatment of L-Name potentiate but injection of L-Arginine had inhibition of corticosterone effects (P<0.05).

Conclusion: This study revealed that glucocorticoid induces anxiolytic effects and these effects probably potentiate by NO inhibitor and reduced by NO synthesis. Therefore, it seems that there are interaction between of glucocorticoid and NO system for control of anxiety behaviors.

Background & Objective: The atherosclerosis of left anterior descending (LAD) coronary artery because of subtending more than 50% of left ventricular myocardial mass, has long been the focus of concern regarding appropriate treatment. This study aimed to evaluate efficacy of Percutaneous Transluminal Coronary Angioplasty (PTCA) with stenting for treatment of proximal LAD disease. Materials & Methods: In this descriptive study, 75 patients with isolated proximal LAD atherosclerotic lesion treated with PTCA and stenting were followed up for 9 months. The stenosis of all patients was documented by coronary angiography prior to enrollment. Exercise tolerance testing (ETT) by Bruce protocol was performed before angioplasty and at the end of follow up period as well. Results: There were 44 (58.7%) males, and 31 (41.3%) females. The mean age of patients was 59.4 (range, 39 to 83 yrs). Clinical outcomes of 73 (97.3%) patients were satisfactory. Only two patients developed re-stenosis during the follow up period. The first patient developed myocardial infarction at the 3rd day of her admission, and the second one had an abnormal ETT after 9 months. Percutaneous coronary revascularization with stenting was performed, and both of them were discharged without any problem. Conclusion: This study demostrated that the nine months prognosis of patients with isolated stenosis of proximal LAD coronary artery that treated by PTCA and stenting was acceptable. This treatment improves clinical status and results in lower hospital adverse event rates and in appropriate clinical outcome.

Background & Objective: Gorgan Gulf, with unique environmental value, has been located at the eastern south region of the Caspian Sea. It has not only valuable fish species such as strugen, Caspian roach, carp and vobla fish which supply a great part of daily protein need of our country and the world, but also its beaches are used for swimming. Therefore Lack of observation for environmental regulations result in entrance of microbial pollutants into Gorgan Gulf and creates dangers both for human health and for marine environment. So the evaluation microbial pollution for these beaches and comparing them with standards is an essential need. This study was done to evaluate microbial pollution for Caspian Sea at Gorgan Gulf. Materials & Methods: 40 sea water samples were collected during spring and autumn of 2004 at Gorgan Gulf for evaluation of sea water in Gorgan Gulf microbial pollution and also the mean total number of bacteria, coliforms, fecal coli forms and fecal streptococci was determined by standard method. Results: The results indicated that the mean total number of bacteria, coli forms, fecal coli forms and fecal streptococcus were 5001/1cc, 1555/100cc, 817/100cc and 59/100cc respectively. Conclusion: Mean results compared with related standard (both for swimming beach and piscicultres) and we found that Gorgan Gulf beaches have been polluted for swimming applications, but it is not the case for piscicultures.

Background & Objective: Glucose Amino Glycans (GAG) are unbranched polysacharides, major components of the basement membrane and play a key role in their molecular organization and function, also have an important role in the pathogenesis of some diseases such as hypertension. Hypertention is probably the most important health problem in several countries. But there is not yet a reliable indicator for early diagnosis of hypertension. The goal of this study was the measurement of serum and 24-h urinary GAG as an exact and early diagnostic marker. Materials & Methods: In this case – control study, 24-h urine and serum samples collected from the 53 patients and 38 persons as matched control normotensive group. Then amount of GAG was measured with spectrophotometery method. Results: Our findings showed that there is a direct relation between 24-h urinary GAG excretion and systolic blood pressure and it increases with increase of systolic blood pressure. Also amount of serum GAG increases in hypertensive patients in comparison with control group. Conclusion: This study showed that the concentration of GAG in sera and 24-h of urine samples increase in systolic hypertention.

Background and Objective: In recent years, the efficacy of low-fat diet has been questioned. One potential adverse effect of reduced dietary fat is a compensatory increase in the consumption of high glycemic index carbohydrate, principally refined starchy foods and concentrated sugar. Such foods other can be rapidly digested or transformed into glucose, causing a large increase in post-prandial blood glucose and insulin level. Review studies have generally found an inverse association between glycemic index and satiety. The aim of this study was to determine the effect of low-glycemic index diet versus low-fat diet on the body weight, body mass index, the percent of body fat mass and waist-hip ratio of obese women. Materials and Methods: In this randomized controlled trial study, 46 obese women with BMI>27 and 18-55 year old randomly divided into low-glycemic index and low-fat diet groups during the course of study and after 6-weeks, body mas index, body fat mass and waist-hip ratio were measured. Data analyzed with t student, t paired student tests. Results: Body weight, BMI, waist - hip ratio, and Triceps skinfold, biceps skinfold, subscapular skinfold, abdominal skinfold decreased significantly in both diet groups. After 6-weeks significant difference was not observed in percent of body fat mass between two dietary groups. Conclusion: This study showed that both low-glycemic index and low-fat diets can equally be effective in body fat, BMI and waist - hip ratio.
