ABSTRACT

Buruli ulcer is a chronic, debilitating infection of the skin and soft tissues caused by Mycobacterium ulcerans. In Côte d'Ivoire, the traditional treatment of this pathology is done orally or cutaneously with Sacoglottis gabonensis. It is on six months of mean depending on the patient condition. The objective of this study is to demonstrate for 35 days the efficacy of the total aqueous extract of Sacoglottis gabonensis stem bark (TAESg) on extensive second - degree induced wounds by burns in Wistar rats. For this purpose, 60 rats were divided into 10 groups of 6 rats/group. Burns are induced on all rats of all groups except group 1. Group 1 received no treatment. Groups 2, 3 and 4 were treated orally and received respectively distilled water, Flukocin® 500 mg at a dose of 14.28 mg/kg bw and TAESg at a dose of 3.5 mg/kg bw. groups 5, 6 and 7 treated by the dermal route, respectively received distilled water, Baneocin® 10 g at a dose of 81.6 mg/kg bw and TAESg at the dose of 5000 mg/kg bw. Batches 8, 9 and 10 treated by the oral route associated with the cutaneous route, respectively received distilled water, Flukocin® 500 mg at a dose of 14.28 mg/kg bw, Baneocin® 10 g at a dose of 81.6 mg/kg bw and TAESg at a dose of 3.5 and 5000 mg/kg bw. Healing activity was assessed macroscopically using scoring methods and planimetrically using percentage shrinkage and healing speed. The results indicated a loss of body weight in rats after induction. After one week of treatment, a highly significant increase in weight by the oral and cutaneous routes and very highly significant by the combination of the two routes, was observed in all of the treated rats with TAESg and the reference substances compared to the treated groups with distilled water. Similarly, macroscopic observation of rat wounds showed a decrease in wound surface area leading to a very highly significant decrease in burn scores and inflammation at the level of the combined pathway. The percentage of shrinkage and the speed of healing experienced a highly significant increase by the oral and cutaneous routes and very highly significant by the combined route. Ultimately, TAESg has healing activity by accelerating the process of wound shrinkage and promoting wound closure through the appearance of epithelial tissues. TAESg has a similar activity to that of Flukocin® and Baneocin®.
