0.05 ) with the CsA group ( 28.15 ? 8.33 )U/d, ( 13.05 ? 2.17 )U/d at the first month and 1 year after the operation. One year after the operation, 21 patients ( 63.63 %) were subjected to anti-hypertensiom, 5 patients ( 15.15 %) to anti-hyperlipidemia treatment and 3 patients ( 9.09 %) to liver protection treatment due to abnormal liver function in FK506 group, while in the CsA group 28 patients ( 90.32 %) were subjected to anti-hypertension, 13 patients ( 41.94 %) to anti-hyperlipidemia treatment and 11 patients ( 35.48 %) to liver protection treatment due to abnormal liver function. There were significant differences between the two groups.Conclusion The small dose low concentration FK506 is effective in the end stage renal disease of diabetic renal allograft recipients and side effect incidence of it was low, and it has almost the same influence on the glucose metabolism as the CsA.
