title: [Peritoneal-fascia-muscle autologous graft in the inguinal canal of rats].
abstract: OBJECTIVE
  To study the fragment of the autologous tissue, built by a peritoneum-fascia-muscle, implanted on the level of the wall of inguinal canal and the spermatic cord of rats aiming to verify the histological behavior of the survive and the tissue incorporation.
  
  
  METHODS
  Thirty-six rats were distributed into four groups. The rats of the group A, B, C and D were submitted to the median laparotomy to obtain the species to be implanted. On the group A, was implanted a tissue compounded by peritoneum and transversal fascia on the wall of the inguinal canal. On the B, the tissue implanted was added a part of rectum muscle of the abdomen and implanted on the wall of the inguinal canal. On the C, the tissue grafted was similar to the groupA, now grafted into the spermatic cord. On the D, the tissue was similar to the group B, now grafted into the spermatic cord.
  
  
  RESULTS
  After 21 days of implant, these tissues presented the following histological alteration: the group A and C, fibroadipous tissue with dilated vessel, Focus of fibrosis' and limphoplasmocitary infiltrated and the groups B and D, fibroadipous tissue with dilated vessels, skeletal muscle and focus of fibrosis. The fibrosis displayed on the groups B and D was more intensive. On the group B, we almost always find the skeletal muscle, while on the group D this tissue was presented in six animals, almost replaced by fibrosis in two and not present in one.
  
  
  CONCLUSIONS
  All the implanted grafts displayed survive and local incorporation, what could be useful on the correction of defects on the inguinal canal, on situations when the autologous tissue was indicated.
