ABSTRACT
This study aimed to evaluate the propolis effects on both the leukocyte and protein profiles of mice and on the closing time of skin lesions made experimentally, clean and infected with Staphylococcus aureus. The first 48 animals were divided into four groups, one treated with pure alcohol solution and three treated with propolis 10% at dosages of 20 mg, 40 mg and 80 mg per 25 g of animal weight in an intraperitoneal single application . Blood samples in the second, and then 10º, 18º and 26º days after treatment were collected in order to perform WBC, proteins and electrophoretic fractionation of proteins. Regarding the healing activity, also 48 mice divided into six groups were used, in whom surgical wounds in the size of 1cm2 were purposely inflicted , after the dissociative anesthesia were applied . Two groups served as control ones, for clean and infected wounds. Two groups of S. aureus with infected wounds and two groups with clean sores were treated with 5% and 10 % propolis, being this concentration choice based on a pilot study previously performed. The results showed that treatment with propolis influences leukocyte and protein concentrations in a dose- dependent manner, with the highest dose triggering leukocytosis with lymphocytosis and increasing the protein fraction of gamaglobulínica, on the 10th day after the start of treatment. It also indicated that the concentration of the solution influence the time of healing of infected wounds, since the process on the group treated with 5% solution happened faster.
