Аннотация
AIM: To analyze experimentally the outcomes of xenotransplantation (cadaveric artery, decellularized cadaveric artery) for tunica albuginea defects repair.
MATERIAL AND METHODS: The study included 60 chinchilla rabbits. Rabbits underwent local replacement of tunica albuginea. Animals were divided into 2 groups (group 1 - human cadaveric artery, group 2 - decellularized cadaveric artery). The result was considered after 7, 14 and 30 days postoperatively.
RESULTS: Tendency to stasis, sludge-phenomenon and ultimately development of fibrosis of transplantation area were histologically observed in group 1 after 30 days. In group 2 luminal surface of decellularized artery was smoothed, fibrin and blood elements were absent. In group 1 mean level of C-reactive protein was 3.86±0.43, 1.17±0.2 and 0.73±0.16 mg/L after 7, 14 and 30 days respectively. In group 2 the same values were 0.33±0.03, 0.23±0.03 and 0.11±0.02 mg/L. Differences were significant (t =-46.28, t = -25.95, t = -14.84; p<0.0001).
