Abstract
Background & Objectives: Cryptosporidium is a coccidial protozoa parasite belonging to subphylum of Apicomplexa. Although it is globally widespread and its species exist all over the world, this parasite was unknown until several years ago. Nowadays it is considered as an important infective agent in Immunocompromised hosts especially patients with AIDS. Due to high mortality rate of this infection in immunocompromised and cancerous patients and because of the popularity of Urmia as one of the animal husbandry regions in Iran and since this disease is likely to transfer from animals to human beings this study was conducted to determine the rate of contamination with this parasite. Methods: This case-control study was performed on 72 children (case) with cancer who referred to oncology clinic of Urmia Imam Hospital during 2001. Another 30 children with normal immune system were selected as controls. To determine the amount of contamination with parasite, two fecal specimens were collected from each patient. After being concentrated with Formalin–Ether, these specimens were examined using modified acid fast method. Results: Three cases ofcryptosporidiosis was seen in the patients (4.16%). Of these, there were 2 patients from the rural area and 1 from urban region. There was no significant relationship between the presence of cryptosporidiosis and living in rural or urban areas. Conclusion: Cryptosporidium was detected in three cases of the patients under study who were undertaking chemotherapy. However since the population under study was small, no statistically significant relationship was found between being immunocompromised and contamination with parasite.

Abstract
Background and objectives: Long term exposure to high levels of cement dust is one of the most important environmental risk factors in cement industries that adversely affect employee's respiratory system. Provided that achieving sustainable development mainly relies on healthy workers, this study aimed at assessing cement dust concentration and its free SiO2 content in an Iranian Portland Cement Industry. Methods: In a cross - sectional study, airborne dust levels was investigated by collecting 64 personal and 35 environmental samples at both inhalable and respirable dust sizes. Dust concentrations were determined by deploying personal samplers in the breathing zone of workers. SiO2 fractions were also measured in 4 samples collected from different part of the factory. Results: Arithmetic average concentrations of inhalable and respirable dust in personal sampling campaign were 58 and 13 mg m-3, respectively. Respective values for inhalable and respirable dust in environmental sampling campaign were 154 and 27 mg m-3. Dust concentrations in 90% of environmental samples and 80% of personal samples exceeded those occupational exposure limit values set for inert dusts i.e. Portland Cement. The average free SiO2 fraction in analyzed samples was 2.86% varying from 2.33% in "packing and loading" area to 3.67 % in "raw mill" section. Conclusion: Free SiO2 fraction as well as the concentrations of cement dust in this study is much higher than those of occupational exposure limit proposed by Iranian Technical Committee of Occupational Health.

Abstract
Background & Objectives: Different factors increase risk of disease transmission in women's barbershop and disinfection of instruments, as a major preventive measure, plays an important role in the control of disease transmission . Therefore, present study was conducted to investigate the quality of barber tools disinfection in women salons in Ardabil in 2009. Methods : In a cross-sectional study , 96 women salons were randomly selected. Data were compiled using a questionnaire, observation, and recording results of microbial cultures from barbering tools and analyzed using χ 2 and descriptive statistics. Results : Personal shaving kits were being used only in 5.2% of barbershops and 56 % of barbers applied Micro 10 as a disinfectant of barbershop tools. 64.6 % of samples were microbiologically positive and Staphylococcus aureus was detected in 53 % of positive samples. Positive results were significantly higher in barbershops that did not follow standard procedure of tools disinfection ( p<0.0001). Conclusion: As a result of our study we suggest the following points to improve population health in the barbershops : training on proper disinfection techniques, promotion of Micro10 application and avoid of unhealthy behaviors in barbershops.

Abstract
Background & Objectives: In endemic area, chemically fighting with carrier of kala azar disease is one of the main ways for reducing disease, and ficam is one of the toxins that is appropriate to eliminate mosquitoes and is from health poison among the pesticides. Therefore, by considering the lasting in nature, using ficam can greatly destroy disease-carrying mosquitoes. Methods: In this cross - sectional study the rate of effect ficam on different vectors species were examined in Meshkinshahr city. First two infected villages, as cases and controls, and 10 households from each village selected and 1000 m2 from the case village was spraying with ficam than 0.3 g /m2. Then, using sticky traps set in the distances were attempted to identify species and Fon (per 2 villages). Results: In the rate of 524 sand fly predating in this study included 70.5% Phlebotomus Kandelakii, 5% F. Papatasi, 7.5% F. Major, 7.5% F. Balcanicus, 9.5% F. longidoctus. In the case village was spraying and , respectively, 3-15 - 30 - 45-60 -75 and 90 days after spraying at about 79.5% - 69.5% - 83% - 90% - 93% - 100% and 100 % sand fly vanished. Conclusion: According to this study can be said that ficam poison with the survival of three months in nature and with average of lethality coverage of appropriate terms of season to prevent from disease Kla-azar and eliminate sand flies and as a poison, appropriate of health before starts up the season of carriers activity. And ficam poison can be used in the whole of region and country.

Abstract
Background & objectives: Vitamin D deficiency and poor sleep quality are important factors in health disorders and are common among women. The aim of this study was to investigate the effect of physical activity on vitamin D levels and improving sleep quality in women.
Methods: This descriptive-analytical study was conducted on active and inactive women (85 individuals in each group), aged 30-48 years that were selected using convenience randomized sampling. The Pittsburgh Sleep Quality Questionnaire was used to assess sleep quality and a score higher than 5 was determined as poor sleep quality. For analysis of data, Kruskal Wallis and Mann Whitney U tests and Spearman coefficient were used at a significance level of 0.05.
Results: The results showed that 54.12% and 28.82% of women had a deficiency and insufficient levels of vitamin D, respectively, and 61.8% had poor sleep quality. Active women had higher levels of vitamin D and better sleep quality compared to inactive women (p<0.05). There was also a direct relationship between vitamin D levels and sleep quality in active and inactive women. However, this association was significant in active women with vitamin D deficiency and inactive women with different vitamin D status.
Conclusion: It seems that physical activity can increase vitamin D levels and improve sleep quality in women. But vitamin D status, especially its deficiency, may be one of the most important determinants of sleep quality in active and inactive women.
