Background & Objective: Enteroparasitic infections constitute a serious public health problem in different populations including developed countries. Patients who receive chemotherapy of cancer have an increased probability of acquiring parsitic infections, generally with a high degree of severity. The aim of present study was to ascertain the frequency of intestinal parasites in patients admitted in oncology ward for chemotherapy. Materials & Methods: In a descriptive study, all the patients whith malignancy who admitted in Sina Hospital in Hamadan, Iran, during 2005 were included. Data including demographic characteristics, type of malignancy, and the time past from the diagnosis entered the questionnaires. A stool specimen were examined for each patients. Data were analyzed using SPSS software. Results: Out of 190 patients, 94 (49.5%) were male and 96 (50.5%) were female. The mean age was 48.518.7 years (12-88 years). Thirty-one (16.3%) patients were involved intestinal parasites. The most common parasites were: Ascaris (41.9%), Giardia (35.5%), Indolimax nana (3.2%), Blastocytis hominis (3.2%), and Cryptosporidium (3.2%). The highest prevalence of intestinal parasites belonged to 40-60 years age group Conclusion: This study indicated that, the prevalence of intestinal parasites in patients undergoing chemotherapy for malignancy is lower than general population, which can be related to the effect of antineoplastic agents.

Background and Objective: Many factors are known to be involved in a number of human pathologies of obesity including serum leptin and thyroid hormones levels. The purpose of this study was to compare the serum levels of leptin and thyroid hormones in obese and non-obese women, in Shiraz-Iran during 2006. Materials and Methods: In this case- control study, 35 women with BMI≥30 Kg/m2 recruited as an obese group (Case group) and 35 women with healthy BMI (BMI<25 Kg/m2) were selected as a control group. General information data were gathered from each sample using questionnaires and face-to-face interviews. Body weight, height, waist and hip circumferences were measured and BMI, WHR and percent of body fat (%TBF) were calculated for each subject. Venous blood samples were drawn from subjects and serum was separated to determine the concentrations of serum leptin and thyroid hormones (T4, T3 and TSH) levels. Results: Mean serum concentration of leptin was significantly higher in obese group than control group (p<0.001). Serum leptin levels positively correlated to anthropometric indices (BMI, WHR, %TBF). No significant difference was observed between obese and non-obese groups in serum thyroid hormones concentration. Serum leptin levels positively related to serum T3 levels (P<0.05). Conclusion: This study indicated that obese women had higher leptin levels compared to non-obese. The interaction between thyroid hormone in particular T3 and leptin can be one of the reason for increasing the serum leptin level among obse women.

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.

Background and Objective: One of the most important routes of hepatitis B virus (HBV) transmission is from asymptomatic carrier mothers to their infants. It has been concluded that over 50% of Iranian carriers have contracted the infection perinatally, making this the most likely route of transmission of HBV in our country. In this study, we assessed the rate of HBV infection in children were born to HBsAg positive mothers that received hepatitis B immunoglobulin (HBIG) and the first dose of vaccine at birth and the second and third of doses of vaccine at 1 and 6 months of age, respectively. Materials and Methods: In this descreptive study, 123 infants born from HBsAg positive mothers assessed and serum sample of these subjects were tested by ELISA technique for detection of HBsAg, Anti-HBs and Anti-HBc markers. Data were then analyzed by the chi-square and fisher exact tests. Results: From 31241 pregnant women with delivery during this 5-years study about 140 (0.45%) of them were HBsAg positive. Children born to these mothers follow-up and 123 serum samples of them tested for serologic markers of HBV infection. HBsAg was found in 0.8% of the children and 91.9% had one or more serologic markers of HBV infection. Protective rate (Anti-HBs positive) and Anti-HBc positive were 82.1% and 8.9% respectively. Conclusion: This study showed that after having focuced on the vertical transmission route for many years, and implementing strategies such as vaccination and HBIG injection to neonates of HBsAg positive mothers, nowadays it seems that we should pay attention to horizontal route of HBV transmission in this area.

Background and Objective: Aircraft as a safe means of transportation may cause occupational diseases and hearing loss. Prevention should be implemented for airport employee. This study was done to detemine the scale of hearing loss among Isfahan airport employees in 2005. Materials and Methods: This historical cohort study was conducted among Isfahan International airport employees. 80 employees were selected in four different case groups, the control group consist of two sub-gourps. The sub-group I (18 subjects) including the adminstrative airport employees (low noise exposed) and the sub-group II (32 subjects) including non-airport employees (non-noise exposed). The sound pressure level was measured and equivalent level (Leq) was calculated for all groups. Also the history of participants about past noise exposure and other confounding variables was detrmined by a questionnaire. Pure tone audiometry was carried out on conventional frequencies (0.5-8 KHz). Results: The mean age of subjects was 40.03±9.75 and 37.85±8.15 for exposed and non-exposed groups respectively. Leq (noise equivalent level) for Ramp and traffic workers was estimated more than 95 dBA. 35.7% (n=10) of Ramp workers were suffering in their right ear from noise induced hearing loss (26-40dB) and 32.1% (n=9) of them in their left ear. Relative risks of noise induced hearing loss in Ramp workers in comparison with control group were 9.4 and 7.5 for right and left ears. A siginificant difference was found between the hearing thresholds of exposed and non-exposed groups (P<0.05). Conclusion: This study showed that occupational exposure to noise cause hearing loss among airport employee. It is suggested strategies of noise assessment and prevention should be implemented for airport employees.

Background and Objective: Gum diseases and dental caries are the most prevalent diseases in societies with different cultures particularly among pregnant women. This study was done to evaluate the oral health status of pregnant women in Gonbad Kavous, northern Iran.

Methods: This descriptive - analytical study was conducted on 400 pregnant women aged 20 to 40 years old in Gonbad Kavous, northern Iran during 2010-11. Demographic and oral examination information was recorded in a chick list. The obtained data were evaluated by DMFT index (Decay, Missing, and Filling Teeth) and OHI-S index (Oral Hygiene Index-Simplified).

Results: The average of DMFT index was 3.29±6.21. There was a significant difference between the place of birth and place of residence of pregnant women with DMFT index (P<0.05). The average of OHI-S index in pregnant women was moderate (0.88±1.36). There was a significant difference between the location of residence and the level of education of pregnant women with OHI-S index (P<0.05). The most important factor to increase DMFT index was the high average of decayed teeth among pregnant women. Regarding the method and duration of observing oral hygiene, the most correct answers were related to method of cleaning teeth (toothbrush and toothpaste) and the least ones were related to the duration of cleaning (3-5 minutes).

Conclusion: DMFT index was high in pregnant women in northern Iran.

Background and Objective: Water resident bacteria are potentially important reservoir of antibiotic resistance genes. This study was performed to evaluate the antibiotic resistance in Escherichia coli strains isolated from raw waters of Golestan province, northern Iran.

Methods: In this descriptive study, 26 samples from Ziarat river water (13 samples pre & 13 samples post treatment) and 36 samples from Azadshahr area springs water (18 samples pre & 18 samples post treatment) were collected. 75 numbers of Escherichia coli bacterium samples (50 isolated from river and 25 isolated from springs) identified and isolated from raw waters of Golestan province, northern Iran by MPN method via differential tests. Susceptibility of Escherichia coli strains to 11 antibiotics (Amoxicillin / Clavulanic acid, Ampicillin, Imipenem, Cefalotin, Cefotaxime, Gentamicin, Amikacin, Tetracycline, Nalidixic acid, Ciprofloxacin and Trimethoprim / Sulfamethoxazole) was assayed by disk diffusion Kirby & Bauer’s method.

Results: 14 spring's raw water samples and 12 river raw water samples contained Escherichia coli. All of the river and springs samples assayed free from Escherichia coli post treatment. All of the Escherichia coli strains isolated from samples showed the similar phenotypical resistance against to surveyed 11 antibiotics. The most significance resistance to Ampicillin (river 94% & springs 88%), Amoxicillin / Clavulanic acid (river 76% & springs 80%), Tetracycline (river 14% & springs 16%) and Cefalotin (river 8% & springs 16%) viewed. Resistance to Trimethoprim / Sulfamethoxazole (8%), Nalidixic acid (2%) and Ciprofloxacin (2%) just viewed in river samples. All of the river and spring isolates were sensitive to Imipenem, Cefotaxime, Gentamicin and Amikacin and demonstrated intermediate resistance to others antibiotics.

Conclusion: Treatment of raw water from springs and rivers caused the eradication of Escherichia coli. As regard to observed phenotypical resistance in springs’ raw waters, presumably with lack of treatment springs’ raw water can be caused the transmission of antibiotic resistance to human body.

Background and Objective: Permanent first molars are susceptible to caries due to their particular anatomical form, early development and lack of knowledge of parents about their permanence. This study was conducted to determine the index of first permanent dental careis (DMF6) and some of its related factors in 12 year-old students.
Methods: This descriptive-analytical study was carried out on 400 students (200 females and 200 males) using combined method (stratified and cluster sampling) from public and non-governmental schools in Gorgan, northern Iran during 2015-16. First permanent molar examination was carried out. The parents' education level, frequency of toothbrushing and daily consumption of sugar-containing snack foods was recorded in a questionnaire. Each decayed, missing and filled first permanent molar tooth was given number one. These numbers were combined to compute the DMF6 index for each individual.
Results: The DMF6 index was zero in 19.5% and the DMF6 index was determined to be between
1 and 4 in 80.5% of the children. The mean DMF6 index was 2.23±0.07 and significantly higher in girls (2.39±0.10) than in boys (2.07±0.11) (P<0.05). The DMF6 index decreased with increasing parental education and the frequency of brushing and reducing consumption of sugary meals.
Conclusion: Dental caries prevalence among 12-years-old students in north of Iran is higher (2.23) than global standard until 2020 (lower than 1). Gender of child, parent’s education, frequency of toothbrushing and consumption of sugar-containing snack foods plays an important role in the rate of dental caries.

Background and Objective: Sodium meta-bisulphite is used as a preservative in food and pharmaceutical industries. The aim of this study was to determine the effect of vitamin E on the improvement of sodium-meta bisulphite-induced complications on ovarian tissue and sex hormones in rats.
Methods: In this experimental study, 70 adult Wistar rats were randomly allocated into 7 groups including control, sham and interventional groups were received vitamin E (200 mg/kg/bw), sodium metabisulfite (520 mg/kg/bw), and sodium meta-bisulphite (520 mg/kg/bw) was combined with vitamin E in 50, 100 and 200 mg/kg/bw doses. Prescriptions were taken as gavage for 30 days. Blood samples were taken from animals to measure LH, FSH, estrogen and progesterone hormones. Ovaries were removed and follicles were counted after tissue sections.
Results: The concentration of estrogen hormones, progesterone, LH, FSH and number of ovarian follicles in the groups receiving sodium meta-bisulphite and vitamin E alone was significantly lower than control group (P<0.05). In animals treated with sodium meta-bisulphite and vitamin E at 100 and 200 mg/kg/bw, no significant difference was observed. However, in animals which were simultaneously treated with meta-bi-sulfite sodium and vitamin E at dose 100 and 200 mg/kg, in compared with the control group, significant improvement was not observed.
Conclusion: Sodium meta-bisulphite consumption with 50, 100 and 200 mg/kg body weight of vitamin E can reduce the effect of sodium meta-bisulphite on ovarian follicles and sex hormones.
