RESUMO

Introduction: The suture wires are materials used in the synthesis of surgical wounds or not, and the interaction of the wire with tissues during the cicatricial process, must have among others objectives, the absence of side effects. Objective: analyze by descriptive histologic study the characteristics of the tissue reply between the tissue adhesive ethyl-cyanoacrylate, the Mononylon wire suture 5-0 and a suture wire made of sugarcane biopolymer in the tissue synthesis. Methodology: forty five male rats of the rattus novergicus albinus wistar race had been used distributed randomly in three groups, knocked down with chloral hydrate 10% (0,4ml/100g of weight). After uniform line incision, in the back skin, reaching skin, cellular and low tissue and hemostasia layer, the synthesis material was applied by the following way: group I, Mononylon 5-0; group II, the tissue adhesive ethyl-cyanoacrylate and group III, the wire made of sugarcane biopolymer. Sacrifice was done in 1, 5 and 10 days after surgery. The segments of skin of specimens were removed, fixed in formol 10% and, later, in the corresponding area to the surgical wound, the parts were sliced, transversally, in three equidistant points in the cut surface, in order to be visualized the structures of the surface to the depth. Results: in first the 24 hours, the tissue reply was similar between the three groups. To the five days, the histologicals characteristics of the group of biopolymer more had been accented. To the ten days the results of the three groups if had been similar. At no moment significant difference between the used materials was observed. Conclusion: the wire made of sugar-cane biopolymer was presented as a viable alternative in the synthesis of wounds
