Abstract: antibiotics are considered the main therapeutic option to treat bacterial infections; however, there is the disadvantage of increasing bacterial resistance. thus, the research of antimicrobials of plant origin has been an important alternative. this work aimed at determining the in vitro antibacterial activity of the essential oil of origanum vulgare l. (lamiaceae) on multiresistant bacteria isolated from biological materials. 24 strains of nosocomial bacteria were used and divided into six different species that were inhibited by the essential oil in the preliminary "screening" which was accomplished by the diffusion technique in agar. mic was determined by the microdilution method, beginning with solutions with the final concentrations: 8 up to 0.125% with the following results: the four samples (100%) of escherichia coli, enterococcus faecalis and mrsa were inhibited by the essential oil at the concentration of 0.125%. three samples (75%) of acinetobacter baumannii at 0.125% and a sample (25%) at 0.5%; klebsiella pneumoniae (75%) at 0.125% and 25% at 0.25%; pseudomonas aeruginosa (75%) at 0.5% and 25% at 0.25%. mic varied from 78 to 83%. it was concluded through the obtained data that there was not difference in the minimum bactericidal concentration (0.5%) of the referred oil for gram positive as well for gram negative microorganisms.

Journal of Biomedicine and Biotechnology , 2012, DOI: 10.1155/2012/184538
Abstract: This study aimed at evaluating the use of hydrogel isolectin in the treatment of second-degree burns. Twenty male rats were randomly divided into two groups (G1 = treatment with hydrogel containing 100 μg/mL Cramoll 1,4 and G2 = Control, hydrogel). After 7, 14, 21, 28, and 35 days, animals were euthanized. On the 7th day, G1 showed intense exudates, necrosis and edema. On the 14th day, G1 showed tissue reepithelialization and moderate autolysis. On the 21st day, G1 showed intense fibroblastic proliferation, presence of dense collagen, and moderate fibrosis. On the 28th day, G1 showed complete tissue epithelialization. On the 35th day, G1 showed modeled dense collagen. The significant wound contraction was initiated from day, 14 in the G1. There were no significant differences in biochemical and hematological parameters analyzed. These results extend the potential of therapeutic applications for Cramoll 1,4 in the treatment of thermal burns.
