Effect of sildenafil on serum creatinine and urea as well as urinary albumin levels of gentamicin-induced nephrotoxicity in rats.

Group	Creatinine  mg/dL	Urea  mg/dL	Albumin  mg/dL
Control	0.53 ± 0.01	26.2 ± 0.24	0.36 ± 0.01
Sildenafil	0.55 ± 0.01	25.8 ± 0.17	0.34 ± 0.01
Gentamicin	3.1 ± 0.1∗°	139 ± 1.48∗°	4.05 ± 0.10∗°
Gentamicin + sildenafil	0.94 ± 0.01∗°×	59.6 ± 1.02∗°×	2.04 ± 0.06∗°×

Data are mean ± SEM of 6–8 rats. ^∗,°,×Significantly different from control, sildenafil, and gentamicin groups, respectively, at P < 0.05.
