The study involved 20 rats, with two burns on each. The rats were divided into 4 groups: untreated; treated with levomekol ointment; treated with levomekol ointment associated
with nanoparticles and an external magnetic field; and treated with magnetic field alone. Histological
examination was conducted on Day 14, and in all groups, in the thermal burn zone of the skin there were
signs of deep three- and four-degree
burns with necrosis spread through the dermis, reaching the muscle.
In the group with levomekol ointment associated with nanoparticles and magnetic field, inflammation
was decreased, and focal granulation tissue formation was observed. Thus, histological studies of the
burn wound process in laboratory animals showed that the use of an innovative biologically active
wound healing agent based on nanoparticles in combination with the levomecol ointment improved
tissue regeneration and accelerated epithelialization, which enhanced the effectiveness of burn wound
treatment. The use of an external magnetic field facilitated targeted delivery of the therapeutic nanosystem
and maintenance of the optimal concentration of the drug in the woun
