(a) Serum creatinine levels in recipients of kidney grafts from donors in G1 (vehicle, n=6), G2 (rhC1INH+ heparin, n=6), and G3 (heparin, n=3). Data are expressed as mean values ±SEM, significance is calculated by two-way ANOVA and Bonferroni’s post-hoc correction (*p<0.05, **p<0.01, G1 vs G2; ††p<0.01, G2 vs G3). (b) Urinary NGAL measured at baseline, day 3, and day 5 post-transplant in recipients of kidney grafts from donors in G1 (vehicle, n=6), G2 (rhC1INH+heparin, n=6), and G3 (heparin, n=3). Data are expressed as mean values ±SEM, significance is calculated by Student’s T-test.
