    Author: Gu Y, Dai K.
    Journal: Zhonghua Yi Xue Za Zhi; 2002 Sep 25; 82(18):1279-82. PubMed ID: 12425812.
    Abstract:
    OBJECTIVE: To study the effect of substitution of porcine small intestinal submucosa (SIS) for rabbit Achilles tendon. METHODS: Porcine SIS was taken out and processed. Part of Achilles tendons of 20 rabbits' right legs were removed and substituted by porcine SIS and the Achilles tendon of the left legs were used as controls. One, four, eight, twelve, and sixteen weeks after the operation 4 rabbits were killed and their right Achilles tendons were taken out to be examined histologically and their maximum load was tested. RESULTS: One week after the operation, the porcine SIS was already fused with the remaining part of rabbit Achilles tendon. Sixteen weeks after all the Achilles tendons looked like normal one. The maximum load of experimental Achilles tendon was 48 N +/- 9 N one week after the operation, and increased gradually. In the 16th week after the operation, the maximum load was 178 N +/- 6 N for the experimental Achilles tendon and 174 N +/- 10 N for the control tendon. The differences of maximum load between different weeks after operation, except that between one week and 4 weeks after, were statistically significant (P < 0.01). CONCLUSION: Substitution of porcine SIS for injured Achilles tendon is effective, thus proving the feasibility of in vivo tissue engineering technology.
