Immobilization of trypsin on polysaccharide film from Anacardium occidentale L. and its application as cutaneous dressing
چکیده انگلیسی

Polysaccharide obtained from Anacardium occidentale L. gum was used for trypsin entrapment using cellulose (gaze) as a support and this preparation was applied as cutaneous wound healing. Trypsin release in vitro and the influence of pH and temperature on activity, stability and storage time of entrapped enzyme were evaluated. The preparation showed that it was still capable to release enzyme even after 48 h. Entrapped enzyme presented an optimal pH and temperature of 8.6 and 55 °C, respectively. Also, it was stable at high temperature (45 °C for 60 min) and wide range of pH, retaining 80% of its initial activity when stored for 28 days at 25 °C. Histopathological analysis of mice skin wound healing under the entrapped trypsin preparation treatment showed an acceleration of fibroblast proliferation, neovascularization of granulation tissue and stimulating effect on the epithelium formation compared to the skin wound under the treatment using preparations without trypsin. These results demonstrate that the trypsin–polysaccharide–cellulose preparation could be used in cutaneous dressing applications for wound healing.
