Comparative study of microvascular density in experimental third-degree skin burns treated with topical preparations...

During the healing process of third-degree skin burns, a very complex response involves different cells and tissues linked together by intra- and extra-cellular mechanisms. For the restoration of damaged tissues, angiogenesis is the key point in the formation of new blood vessels. By their emollient, astringent, antiseptic, anti-inflammatory, biostimulator, epithelizing and cicatrizing effect, active principles from natural products contribute to the acceleration of the wound-healing process. In our study, we investigated the angiogenesis process in experimental model of third-degree skin burns treated with three topical preparations (cold-creams) containing 10% herbal extracts, comparing with 1% sulfadiazine cream and cold-cream base respectively. By their biostimulator, epithelizing and cicatrizing effect, cold-creams with herbal extracts are locally modulators of the cellular response and support the wound healing. The phytocomplex stimulates the favorable evolution of the burnt skin wounds and the development of neoangiogenesis capillaries.
