The aim of the experiment was to do a valuation of the effect of the sodium diclofenac on the collagenous sinthesis in abdominal wall healing. It was used 40 male Wistar rats to do longitudinal laparotomies with a standardized technique, divided into 2 groups: One without the drug (control group) and another group wich were administrated sodium diclofenac (3mg/kg) every day for 4 days. In the 7th and 14th postoperative day, 10 animals of each group were submitted to euthanasia and the front abdominal wall involving the scar was removed to be prepared to hystological analysis. The segments were prepared with Hematoxilyn-Eosin and Picrosirius Red F3BA, in order to do either a general view of healing process or a quantitative valuation of collagenous. The resultant data were submitted to statistical analysis. It was conclued that the abdominal wall scar in rats treated with sodium diclofenac had less collagenous fibres in the 7th and 14th postoperative days than rats from the control group.
