[Artificial biological skin for preventing adhesion of repaired tendon in white rats]

To study the effect of tendon healing and adhesion after tendon repaired using the artificial biological skin (Biofill) produced in Brazil, we divided randomly 46 rats [correction of mice] into groups, compared the pelvic limbs with themselves, observed by eyes and light microscopy, and made biomechanical and histological detection in 1st, 2nd, 3rd and 4th weeks postsurgically. The results showed that the speed and strength of tendon healing had light affect in three weeks after operation, and had no difference between experimental groups and control groups after 4 weeks. It is indicated that artificial skin "Biofill" can effectively prevent tendon adhesion after tendon repaired and have not obviously influenced in the intrinsic self-healing process of tendon.
