Kidney weight, renal size, and cortical thickness (n = 3–8)

(A) Renal ultrasound images of rats at the age of 12, 18, and 21 months in each group.

(B) Right renal volume at the age of 12, 18, and 21 months in each group.

(C) The trends of right renal volume at the age of 12, 18, and 21 months in each group.

(D) Renal weight/body weight at the age of 12, 18, and 21 months in each group.

(E) The trends of right renal weight/body weight of rats in each group with aging.

(F) Right cortical thickness at the age of 12, 18, and 21 months in each group.

(G)The trends of right cortical thickness of rats in each group with aging. Values are presented as means ± SD. ▲ p＜0.05, ▲▲ p < 0.01, ▲▲▲<0.001, ▲▲▲▲p＜0.0001 versus the control group, ∗p < 0.05, ∗∗p < 0.01, ∗∗∗p < 0.001 versus 1/6NX group, ##p＜0.01 versus the UNX group.
