title: [An exploratory study of preoperative analysis on histocompatibility in porcine allo-kidney transplantation].
abstract: Human tissue typing methods were employed in developing a porcine allotransplantation model. 23 Chinese Sichuan White Pigs(2-3 months old, 17.5+/-4.6kg, with clear family background) were selected for tissue typing, ABO blood type cross reaction, complement-dependent cytotoxicity (CDC) cross reaction and one way mixed lymphocyte reaction (MLR). 6 pairs of swine that showed better matching results were selected as donors and recipients. Single-kidney orthotopic transplantation was conducted after removing both kidneys of the recipient. Five recipients showed low matching results (MLR ranging from 2175 to 3560, CDC from 1 to 4); of them, 2 died of operation, 2 died of acute renal tubular necrosis and accelerating rejection 4 days after operation respectively, and 1 died of acute renal tubular necrosis 4 days after operation. 6 recipients showed high matching results (MLR ranging from 982 to 1916, CDC from 2 to 4); of them, 1 died of anaesthesia during operation, 3 died of accelerating rejection and acute rejection 2 weeks after operation respectively, 1 had good kidney function, and 1 presented weak rejection 1 week after operation but the kidney function came back to normal afterwards. Human tissue typing methods could be adopted in developing the porcine model. Hyperacute rejection could be avoided by screening ABO blood type, CDC and MLR tests. However, based on these primary data, it was hard to evaluate the predictive values of CDC and one-way MLR for accelerating rejection, acute rejection and graft chronic dysfunction. Further research by expanding experiments in these aspects is still going on.
