title: Comparison of FK 506, mycophenolate mofetil, and aminoguanidine effects on delay of corneal allograft rejection in an experimental model of low-risk and high-risk keratoplasty.
abstract: The purpose of our study was to compare the effectiveness of immunosuppressive drugs on the prevention of allograft rejection in a murine model of low-risk and high-risk keratoplasty. The therapy included FK 506 (tacrolimus; 0.2 mg/kg), mycophenolate mofetil (30 mg/kg), aminoguanidine (0.1 g/kg), and combination of FK506 + mycophenolate mofetil or FK506 + aminoguanidine. The results obtained from the Gray's survival model stratified according to the type of subjects suggest that a major rejection risk reduction was achieved using FK506; good results also were obtained for mycophenolate mofetil. Although the point estimates of both the survival and relative risk of rejection suggest a deferred effect of the combination FK506 + mycophenolate mofetil, this finding did not prove statistically significant.
