Abstract
Background & Objectives: Pools and Saunas are one of the most public areas that may cause superficial and cutaneous mycoses in humans. So investigating the fungal flora in the mineral swimming pools like Sarein area can remove or reduce the contamination or prevent the probablity of fungal infection. Methods: A total of 284 samples from 11 mineral swimming pools were taken of which 214 were from pools, sauna Jacuzzis, tubs and showers which were covered by sterile moquette and 70 were from water in saunas, jacuzzis, tubs and showers which were collected in sterile test tubes. All of the samples were cultured in standard method on sabouraud dextrose agar (SDA), sabouraud dextrose agar+oleic acid (S+O) and sabouraud dextrose agar+ chloramphenichol+cyclohexamide (SCC) medias, then identified macroscopically (colony morphology )and microscopically. Results: From 284 samples, 193 were contaminated with fungi. The most frequently isolated species in 11 pools were Aspergillus fumigatus (22/79%), Aspergillus flavus (15/54%), Aspergillus niger (15/54%) and Penicillium (14/5%) respectively. On the other hand, Ulocladium, Sepedonium, Acremonium, Pscilomyces, Stemphylium and Streptomyces with 0.51 % were the least frequently isolated species. In this study, no dermatophytes or other true dimorphic pathogenic fungi were isolated from samples. Conclusion: So it can be concluded that routine hygiene inspections such as disinfection of pools, personnel training and following hygienic rules were much effective in lowering the comtamination. Also mineral waters of these pools can be growth inhibitors of pathogenic and dermatophytic fungi.

Abstract
Background & Objectives: Formation of myelin depends on maturation and development of the axonal cytoskeleton andmitochondria. Collagen gel can specifically play role in the regulation and development of axonal cytoskeleton. Methods: This research is an experimental study in which forty eight male rats (200-250g) were used. After axotomy, 1 cm segment of the sciatic nerve in rats was removed, and the gap was then bridged by one of the four following methods: polyvinylidene fluoride or PVDF + Collagen gel, Autograft, sham and control. Sciatic nerve was studied by electron microscope by the end of the 4th week and the 12th week. Results: By the end of the 4th week after the regeneration the number of unmyelinated axons in autograft and Collagen Gel was not significant, by the end of the 12th week, the number of unmyelinated axons in autograft group was superior to that of nerve growth factor group (P<0.01). After 12 weeks of regeneration, microtubular density values of normal and autograft groups were not statistically different. The cristae of axonal mitochondria in experimental groups are orientate parallel with its long dimension. Conclusion: The results of study indicated that because of its positive effect on the growth and development of microtubules and mitochodria, collagen Gel combination with PVDF can be used to repair peripheral nerve injuries.

Abstract
Background & objectives: Successful implementation of diabetes care can reduce acute and chronic complications of diabetes. This study was conducted to evaluate the quality of care according to a care scoring system among people with type 2 diabetes referring to the diabetes clinic in Ardabil.
Methods: This cross sectional study was conducted in 2014 and a total of 300 people with type 2 diabetes in age range of 20-70 years old were included via convenience sampling. Data were collected by an interviewer using a structured questionnaire and checklist. Each patient was classified according to a quality of care scoring system into 3 categories: ≤10, 15-20, >20. Statistical analysis performed by SPSS v.20 software and descriptive analysis used to display data as frequency tables and graphs. Analytical tests such as ANOVA, Kruskal-Wallis, Chi squared, and fisher exact test were also used to analyze the data.
Results: The mean age of patients was 54.13 ± 9.13 and the majority of them were women (72.3%). The mean of BMI and HbA1c was 29.58 ± 4.77 and 8.93± 2.13, respectively. The mean of FBS was 191.18 ± 84.23 and the average length of disease was 7.74±5.89 years. The mean of quality of care score among participants was 23.20±9.99. About one-third of patients (29.7%) had a quality care score ≤10, half of them (51%) had a score between 15-20, and only 19.35% had a score >20. There was an association between HbA1c, FBS, diastolic blood pressure, cholesterol and LDL with a quality of care score which was statistically significant (p<0.05).
Conclusion: In this study there was a gap between the current quality of care of patients and recommended standards. Therefore in order to minimize the current barriers and problems it is recommended to implement an effective interventional program. In addition, using a quality care scoring system is a rapid, easy and valid method for evaluating diabetes quality of care.

Abstract
Background & objectives: The purpose of this study was to determine the bacterial bioaerosols in indoor air of Ardabil universities and to investigate the factors affecting their concentration in Ardabil city.
Methods: Air sampling was performed using Andersen single-stage sampler at a flow rate of 28.3 liters per minute and a respiratory range of 10 min. In this study, trypticase soy agar containing cycloheximide antibiotic was used for bacterial culture. Biochemical tests such as DNase, catalase, oxidase, coagulase, bile esculin hydrolysis test, urease, citrate test, antibiotic resistance to novobiocin, bacitracin and optochin were used for identification and differentiation of isolates.
Result: The mean bacterial concentration in Ardabil university of medical sciences in the open air, outside the college, the halls, the classrooms and the staff rooms was 18, 88.4, 76.6, 77.4 CFU/m3 , respectively. The concentration of bacteria in Islamic Azad university of Ardabil in the open air, outside the college, the halls, the classrooms and the staff rooms was 103, 97, 124, 132 CFU/m3, respectively. The dominant species of bacteria in indoor air were Staphylococcus aureus, Staphylococcus epidermidis, Actinomycetes and Bacillus, respectively.
Conclusion: According to the results of this study, it is found that the concentration of bacterial bioaerosols in indoor air is not more than standard, but the abundance of bacterial species can cause lung, intestinal and other diseases in academic personnel, staff and students in the long-term.
