Abstract
The aims of the present study was to:
1. Evaluate the effect of thermal burn wounds on guinea pigs by measuring some hematological and biochemical Parameters with /or without treatment.
2. Investigate the effect of topically treatment with Propolis on thermal burn wounds.
3. Investigate the effect of orally and topically treatment with Propolis on thermal burn wounds.
4. Comparing the effect of propolis treatment with those of silver sulfadiazine (SSD), the most widely used burn treatment The skin works as a barrier to the environment, which is responsible for protecting the organism from water loss and penetration of harmful substances. If this barrier is disturbed by mechanical or thermal action, the skin starts a complex repair mechanism known as wound healing.
The seriousness of a burn depends on how deeply the burn has affected the skin tissue and the surface area of the body affected. Burns are commonly grouped based on how deep the tissue is burned. They may be grouped into superficial (first-degree), partial (second-degree), and full (third-degree) thickness burns. The superficial thickness burn only affects the epidermal layer of the skin while partial thickness burn involves the epidermal layer as well as a varying thickness of the dermis. Thus, partial thickness burn can be further divided into superficial partial and deep partial thickness burns. In a deep partial thickness burn, there is damage in the deeper structures of the dermis involving sweat glands and hair follicles. Superficial thickness and superficial partial thickness burn wounds can heal spontaneously if they do not become infected.
If the burn destroys the more superficial part of the dermis as well, epithelial cells from the deep parts of hair follicles will grow long the interface between the living dermis and dead dermis and will form new epidermis at this level (Hinman and Maibach, 1963). However, if the inflected damage extends below the bases of the hair follicles, regrowth of the epidermis can occurs so slowly that a skin graft would be necessary (Cormack, 1987).
Healing requires the collaborative efforts of various tissues and cell lineages. It involves aggregation of platelets, clotting of blood, fibrin formation, an inflammatory response to injury, alteration in the ground substances, angiogenesis and re-epithelialization.
