NATURAL RUBBER - PROPOLIS MEMBRANE IMPROVES WOUND HEALING IN SECOND-DEGREE BURNING MODEL.

Our aim was to evaluate effects of natural rubber membrane (NR) associated with aqueous propolis extract (P) on the wound healing in rats burn model. The membranes were characterized for wettability and pore presence after the membrane preparation by casting the liquid solution in Petri dishes, at different temperatures (27 and 60 °C). Male Wistar rats were divided into treatment groups (n = 5 per group: control without treatment, silver sulfadiazine, NR, NRP) initiated immediately after second-degree burn and maintained during 10 days.
