【 摘 要 】

OBJECTIVE: Surgical scar tensile strength may be influenced by several factors such as drugs, hormones and diet. The purpose of the present study was to determine the influence of a shrimp-enriched diet on the tensile strength of rat scars. METHODS: Forty male Wistar rats were submitted to a 4 cm dorsal skin incision and the wounds were sutured with 5-0 nylon interrupted suture. The animals were divided into two groups: Group 1 (control) received a regular diet, and Group 2 (experimental) received a shrimp-enriched diet. The two diets contained the same amounts of proteins, lipids and carbohydrates. The rats in each group were divided into two subgroups according to the time of assessment of the scar tensile strength: subgroup A, studied on the 5th postoperative day, and subgroup B, studied on the 21st postoperative day. RESULTS: The tensile strength of the scar on the 5th postoperative day was lower in the animals that received the shrimp-enriched-diet (303.0, standard error of mean= 34.1) than in the control group (460.1, SEM = 56.7) (p<0.05). CONCLUSION: A shrimp diet reduces the tensile strength of the scar. The next step of this study will be to clarify the mechanism in which shrimp affects tensile strength.
