Abstract:
BACKGROUND: Recent studies have reported that more and more methods were used to prevent and cure tendon adhesion following tendon rupture by repairing tendinous sheath. Especially, amnion membrane is commonly used to effective prevent and cure adhesion and promote healing of biomembrane; however, the effect on tendon adhesion needs to be further studied. OBJECTIVE: To verify the efficacy of amnion membrane preserved in Honghua injection on preventing and curing tendon adhesion following transplanting into foot flexor tendon. METHODS: Bilateral foot flexor tendons of 32 healthy mature chickens were cut off. By anastomosis, amnion membrane preserved in Honghua injection was transplanted into left foot flexor tendon, considering as experimental group. Right foot flexor tendons were randomly divided into two groups: blank control group, anastomosis was performed alone; positive control group, amnion membrane not preserved in any injections was transplanted. At 4 weeks after fixation by plaster cast, sliding function of tendon was detected using biomechanics, and local samples were obtained for histopathological observation. RESULTS AND CONCLUSION: In the experimental group, broken end of left tendon was well healed; fiber tissues were formed surrounding tendon; tissue adhesion was not observed surrounding tendon. Proliferative quantity and adhesion of fiber tissues, as well as content of hydroxyproline in the experimental group were significantly less than in the blank control and positive control groups (P < 0.05, P < 0.01); total inflexion angle of articulationes digitorum pedis and slipping distance of flexor digitorum profundus tendon in the experimental group were significantly greater than in the blank control and positive control groups (P < 0.05, P < 0.01). The results indicated that amnion membrane preserved in Honghua injection might prevent tendon adhesion and effectively promote tendon healing.
