Evaluation of the Larval Therapy in the Healing Process of Infected Wounds with Pseudomonas Aeruginosa in Rabbits

Introduction. During the last two decades the larval therapy has reemerged as a safe and reliable alternative for the healing of cutaneous ulcers that do not respond to the conventional treatments. Objective. To evaluate the use of the larvae of Lucilia sericata as a treatment for infected wounds with Pseudomonas aeruginosa in an animal model. Materials and methods. Twelve rabbits were randomly distributed in 3 groups: the first group was treated with larval therapy; the second was treated with antibiotics therapy and to the third no treatment was applied, therefore was established as a control group. To each animal a wound was artificially induced, and then a suspension of P. aeruginosa was inoculated into the lesion. Finally, every rabbit was evaluated until the infection development was recognized and treatment was set up for the first two groups according with the protocols mentioned above. Macroscopic evaluation of the wounds was based on the presence of edema, exudates, bad odor, inflammation around the wound and the presence of granulation tissue. The healing process was evaluated by monitoring histological changes in the dermal tissue. Results. Differences in the time required for wound healing were observed between the first group treated with larval therapy (10 days) and the second group treated with conventional antibiotics therapy (20 days). Conclusion. The L. sericata larva is and efficient tool as a therapy for infected wounds with P. aeruginosa.

Mitificación y oralidad en el otoño del patriarca de Gabriel García Márquez

El actual documento presenta los resultados de una investigación que vengo desarrollando hace algunos años sobre El Otoño del Patriarca. Esta investigación sufrió una importante variación en torno a la reflexión sobre los propósitos de la lectura filosófica de un texto literario, y ha sido consecuencia de, por un lado, un desplazamiento en la determinación de las relaciones entre las dimensiones del lenguaje, el poder, el tiempo y el espacio abiertos por la narración, y por otro, de una diferencia de concepción sobre la formación discursiva de estas relaciones en El Otoño del Patriarca como obra narrativa, oral y poética.
