    Abstract Background and Objective: Atrophic rhinitis is a main problem in developing countries. Different surgical methods were used to treatment of the disease but it was not successful. The objective of this study was to evaluate the efficacy of modified Young method in treatment of atrophic rhinitis. Methods: This interventional study was performed on patients with atrophic rhinitis in Babol during 1986-1990. All patients were operated by modified Young method and also we followed for one year. Findings: This study was done on 10 cases (9 cases were female and 1 was male) and they were at the 32-45 age group. All cases were completely treated and there was not any relapse after one year of follow up. Conclusion: Since, the outcome of this method was successful, it was suggested all patients with atrophic rhinitis should be treated by this method.

    Abstract This work focuses on the structure, bioactivity, corrosion, and biocompatibility characteristics of chitosan-matrix composites reinforced with various amounts of fluoride-doped diopside nanoparticles (at 20, 40, 60, and 80 wt%) deposited on stainless steel 316 L. Bioactivity studies reveal that the presence of the nanoparticles in the coatings induces apatite-forming ability to the surfaces. Based on electrochemical impedance spectroscopy and polarization experiments, the in vitro corrosion resistance of the substrate was enhanced by increasing the level of the nanoparticles in the coating. The sample containing 60% of the nanoparticles presented the highest osteoblast-like MG63 cell viability, in comparison to the other prepared and even control samples. Also, the cell attachment on the surfaces was improved with increasing the amount of the nanoparticles in the coatings. It is eventually concluded that the application of chitosan/fluoride-doped diopside nanocomposite coatings improves the bioperformance of metallic implants.

    Abstract Introduction: Retinopathy is one of the most important complications of diabetes mellitus that results from chronic hypeglycemia, oxidative stress and inflammation. Tumor necrosis factor-beta2 (TGF-β2) is an important factor in the inflammation pathway due to hyperglycemia. Garlic is one of the most frequently used plants in Iranian diets that has hypoglycemic and antioxidant propertis. So, this study aimed to examine the effects of aqueous garlic extract on TGF-β2 gene and protein expression in retinal tissues of type 1 diabetic rats. Methods: In this experimental study, 24 male Wistar rats were divided into four groups (n = 6) including control rats, type 1 diabetic rats, type 1 diabetic rats treated with the garlic extract and garlic control. To induce diabets type 1, streptozotocin (STZ, 65 mg/kg) was used. Seven days after the STZ injection, the glucose level was measured by a glucometer. at the end of the treatment period(30 days, gavage of the garlic extract (1mL/100g)), the serum sample was isolated and stored in -20ºC for determination of the glucose level. Also, the ratschr('39') eyes were removed and their retial tissues separated quickly and stored in -70ºC for gene expression evaluation and protein assay. To determine the gene expression level, RNA extraction, cDNA synthesis and real-time polymerase chain reaction were performed. The TGF-β2 protein level was also measured by the ELISA kit. Results: The TGF-β2 mRNA expression was increased 1.37 fold in diabetic rats compared to control rats and decreased 1.96 fold in garlic-treated diabetic rats compared to untreated diabetic rats. The TGF-β2 protein level was increased 3.08 fold in diabetic rats compared to control rats and decreased 2.56 fold in garlic-treated diabetic rats compared to untreated diabetic rats. Conclusion: Garlic extract significantly decreased the TGF-β2 level in retinal tissues of diabetic rats. The TGF-β2 is an important factor in inflammation and damage to retinal; so, it is logical that garlic consumption can reduce diabetes ...

    Abstract In this study fungal contamination of five indoor public swimming pools in Zanjan was investigated using membrane filtration and sterile carpet sampling methods. Nine samples from water and related areas of each swimming pool were tested for the presence of the fungi and final diagnosis was done by slide culture technique to determine the species. The most common fungi isolated from swimming pools included Dermatophyte ( Trichophyton mentagrophytes and Epidermophyton floccosum ) 0.4%, Yeasts 21.8% and filamentous fungi 77.7%. Out of saprophyte fungi 24.8% were separated from pools margin, 22.6% from dressing rooms, 16.8% from pools water and 11.4% from shower- bath. Also yeasts fungi were separated from pools water 7.3% and from shower-bath 3.1% and Dermatophytes were separated from dressing room 0.2%. The fungal contamination of these swimming pools under specific condition could be an alarm for induction of infections and allergy in immunocompromised hosts.

    Abstract Determination of seroepidemiological survey of Toxocara infection in 810 sera from children inhabitants in rural and urban area of Zanjan (North-West of Iran) was adjusted for specific antibody level against of second stage larvae of Toxocara for excretory and secretory antigens based on ELISA technique. In contrast of the other studies, the overall seroprevalence was quite low, reaching to 2.7% out of 810 samples was positive to anti Toxocara species antibodies. Neither age nor gender seemed to be significant factor to positive serology. Seroprevalence of anti Toxocara antibody were detected in 8 out of 494 (1.6%) children from urban area, whereas 316 sample (4.4%) were the positive in the rural area. Positive children who had contact or ownership of cats and dog were 6.9 and 3.9%, respectively. Albeit, concerning to this study, seroprevalence of toxocariosis is lower than other countries and other studies in Iran. But protections of toxocariosis in children must be taking into account in public health program. Suggest that increase of hygiene education would be a crucial affective on population to reduce infection risk factor and zoonotic disease.
