Table 2. BUN and creatinine concentrations of the Control, Sham and chronic kidney disease (CKD) groups at 8 and 12 weeks of experiment.

	8 weeks			12 weeks
	Control	Sham	CKD	Control	Sham	CKD
BUN (mg/dL)	30.5 ± 3.78 (n = 19)	29.73 ± 2.06 (n = 16)	70.1 ± 14.76 * # (n = 15)	30.85 ± 3.75 (n = 19)	32.1 ± 4.34 (n = 19)	60.07 ± 17.2 * # (n = 17)
Creatinine (mg/dL)	1.01 ± 0.4 (n = 19)	0.75 ± 0.12 (n = 16)	1.37 ± 0.35 * # (n = 15)	0.74 ± 0.23 (n = 19)	0.68 ± 0.13 (n = 19)	1.11 ± 0.29 * # (n = 17)

Values are expressed in mean ± SD. n = number of animals.

The * indicates differences from Control and ^# differences from Sham group (p<0.05), on the same experimental period.
