title: [Wound-healing effect of carbopol hydrogels in rats with alloxan diabetes model].
abstract: The effects of 0.5% hydrogels of acrylic polymers (carbopol), antibiotic ointment based on polyethylene oxides (levomekol), silver-containing creams (dermazin and argosulfan), silver sulfadiazine ointment with epidermal growth factor (ebermin), and wound-covering fabric of antibacterial cellulose with poviargol and zero-valent silver (aquacell-Ag) on skin repair processes have been evaluated in comparative experiments on rats. The wound-healing effects were characterized by the time of cleansing and epithelization, rate of suppuration, index of healing, and skin impedance under conditions of necrotic skin lesions on the background of diabetes. It is established that local application of carbopol hydrogels modified by electric (frequency-modulated) signal with antiseptics (poviargol) and nanostructural components (natural fullerene complex) shortens the period of wound cleansing from detritus on the background of decompensated diabetes by 3.6 days (p > 0.05), accelerates healing by 8.4 days (p < 0.05), reduces the frequency of suppuration by 23.3% (p < 0.05), exhibits strong bactericidal effect against wound infections by pathogens, and restores tissue impedance. Thus, hydrogels based on low-crosslinked acrylic polymers are a promising basis of wound-healing formulations for the treatment of necrotic lesions on the background of diabetic foot syndrome.
