Chitosan gel formulations containing egg yolk oil and epidermal growth factor for dermal burn treatment

Abstract

In the present study chitosan based gel formulations containing Egg Yolk Oil (EYO) and Epidermal Growth Factor (EGF) were formulated successfully aiming at enhanced topical treatment of dermal burns the combination of traditional approaches with modern drug delivery systems. Physicochemical properties of the formulations were analyzed and efficacy of the formulations prepared were evaluated versus a commercial product; Silverdin (R) (1% silver sulfadiazine) in vivo on Wistar rats. Burns were generated on the back of the rats and at predetermined time intervals tissue samples were collected and evaluated histologically. The analyses showed that chitosan based gel formulations containing Egg Yolk Oil (El) and chitosan based gel formulations containing EYO and EGF (M1) formulations seem to be better alternatives for Silverdin (R) with a significant difference (p<0.05) considering healing ranks of tissue samples.
