[Diaphragm frozen homograft for rats' abdominal wall defects repair].

Objective: To analyse the morphology and biomechanics of diaphragma frozen homografts used for rats' abdominal wall defects repair.

Animals were euthanized after 3 and 6 months and abdominal walls were avaliated histologically with H/E and Picrosiriud Red staining and tensiometric evaluation.
