Abstract
Natural rubber latex membranes of Hevea brasiliensis has been used as a dressing for cutaneous ulcers. Moreover, latex membrane also has been broadly used in controlled drug release systems development. Barbatimam have several medically useful properties, such as anti-inflammatory, antimicrobial, antioxidant and healing properties, associated to high tannin contents. Its organic fraction (ethyl acetate) presents ~ 20% total tannin content in the composition. The aim of this work is to evaluate the barbatimam extract and fractions release by latex membrane employing in a High Performance Liquid Chromatography (HPLC). Evaluation of surface roughness and morphology of different porous membrane will realized by Atomic Force Microscopy (AFM). It will also be analyzed the adhesion of fibroblasts cells on porous membranes by AFM. Peptide Mass Fingerprinting (PMF) analyzes of fibroblast cultures will be performed to detect differentially expressed proteins as a result of the action of barbatimao extract, fractions, latex membrane and natural rubber latex membrane with compounds exposed to the cells. After that, molecular signaling analysis will be performed using real time PCR (qPCR) and Western blotting techniques in these cultures. In this way, it is hoped that the results can indicates this product as a new technology in favor of the human benefit. (AU)
