Tissue repair and wound healing are complex processes that involve inflammation, granulation, and remodeling of the tissue. The potential of various statins including atorvastatin (ATR) to improve the wound healing effect was established. The aim of this study was to formulate and evaluate the efficacy of topical application of ATR-based nanoemulgel on wound healing. The prepared formulations (ATR gel, ATR emulgel, and ATR nanoemulgel) were evaluated for their physical appearance, rheological behavior, in vitro drug release and ex vivo drug permeation. The in vivo wound healing effect was evaluated in wound-induced rats. The prepared ATR gel formulations showed good physical properties and were comparable. The release profiles of drugs from gel, emulgel, and nanoemulgel were distinct. Skin permeation potential of ATR was significantly (p < 0.05) enhanced when formulated into nanoemulgel. In vivo wound healing studies showed that ATR nanoemulgel exhibited the highest percent wound contraction. Histopathological assessment showed marked improvement in the skin histological architecture after 21 days of ATR nanoemulgel treatment. In conclusion, the data demonstrated here signify the prospective of ATR nanoemulgel as an innovative therapeutic approach in wound healing.

Wound Healing Effect

Native skin repair requires wound care products that not only protect the wound from bacterial infection, but also accelerate wound closure and minimize scarring. Nanomaterials have been widely applied for wound healing due to their multifunctional properties. In a previous study, we prepared and characterized electrospinning zinc oxide/silver/polyvinylpyrrolidone/polycaprolactone (ZnO/Ag/PVP/PCL) nanofibers using ZnO and Ag nanoparticles, and evaluated their antibacterial effect in vitro. In this work, further characterization studies were performed, which confirmed that the ZnO/Ag nanoparticles were physically embedded and evenly distributed in the ZnO/Ag/PVP/PCL nanofibers, enabling the sustained release of Ag and Zn. In addition, the bimetallic nanofibers showed satisfactory fluid handling and flexibility. In vivo wound healing and histology studies showed that the ZnO/Ag/PVP/PCL nanofibers had a better anti-inflammatory, skin tissue regeneration, and wound healing effect than monometallic nanofibers or a commercially available wound plaster (Yunnan Baiyao). Therefore, ZnO/Ag/PVP/PCL bimetallic nanofibers may be a safe, efficient biomedical dressing for wound healing.

New hydrogel dressings containing the herbal medicinal substance "Alkhydin", obtained from the Kirghiz (Alhagi kirghisorum Schrenk), grown in Kazakhstan, were obtained by radiation irradiation of the initial reaction mixture (IRM). Poly-<br />N-vinylpyrrolidone (PVP) with a molecular weight (MM) of 1 ppm was used to prepare hydrogel dressings as the main gelling polymer for IRM, agar-agar and lowmolecular polyethylene glycol MM = 600 were used as auxiliary substances. The main regularities of the formation of the three-dimensional structure of PVP under conditions of irradiation of IRM are investigated. It is shown that with increasing PVP in IRM, as well as irradiation dose, the yield of gel fraction increases and the degree of swelling decreases. Obviously, these effects are due to an increase in the degree of cross-linking of the polymer network formed. For the obtained hydrogel dressings containing the herbal medicinal substance Alkhydin, cytotoxic effects on the culture of mouse embryonic fibroblasts obtained by primary trypsinization were studied. The results obtained in this case testify to the absence of a cytotoxic effect on the cell culture. In conditions "in vivo" in rats using the model of thermal skin burn, the wound healing effect of hydrogel dressings with "Alkhydin" was studied. It is shown that such bandages show a pronounced wound-healing effect. This is evidenced by a higher rate of reduction in the area of the burn wound treated with a hydrogel dressing compared to the control.
