title: The optical analysis of the abdominal wall using the biospeckle after implants of polypropylene mesh in rats.
abstract: OBJECTIVE
  To evaluate an experimental animal model to study the abdominal tissue activity considering its interaction with a polypropylene mesh, through the use of one of the optical phenomena of light Laser, the biospeckle.
  
  
  METHODS
  Fifty Wistar male rats were divided into four groups: Group 1: ten animals not submitted to surgery; Group 2: ten animals submitted to surgery without polypropylene mesh; Group 3: 20 animals submitted to surgery followed by the mesh placement; Group 4: (sham) with ten animals. None of the animals presented post surgical complications being submitted to the optical tests at the 20th postoperative day.
  
  
  RESULTS
  The analysis from the biospeckle tests, comparing the medians and standard deviations with T Student test, indicated that no significative difference was observed on the abdominal wall tissue activity in the four groups considered, with and without polypropylene mesh prosthesis implantation.
  
  
  CONCLUSIONS
  The animal model is viable and the biospeckle open ways for a great number of experiments to be developed in evaluating tissue activity.
