چکیده
Silver salts and nanosilver (NS) are the common antimicrobial used in the treatment of chronic wounds, so they are important to assess their dermal toxicity. Therefore, in this study, the possible dermal toxicity of NS particles and silver nitrate (AgNO۳), was tested by determining the serum level of transforming growth factor-β۱(TGF-β۱) and study on of mouse skin tissue. In this study, ۳۰ BALB/c mice were randomly allocated into NS, AgNO۳ and control groups (n=۱۰). After general anaesthesia and shaving the back of all animals in near the vertebral column, in NS group, a volume of ۵۰µl ۱۰ µg/ml of nanosilver solution (۴۰ nm), in AgNO۳ group, with the same amount of AgNO۳ solution (۱۰۰ µg/ml), in control group, the same amount of distilled water was added to the sterile bandage of mice. The shaved areas were covered with sterile bandage that and fixed with cloth glue. After ۳ and ۷ days, the bandages were opened and serum level of TGF-β۱ was measured using standard kits and preparation of skin samples for histological analysis. Results showed toxicity of NS and AgNO۳ by a significant reduction of TGF-β۱ without any damage to skin.کلیدواژه ها

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.
کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
