Mean ± SDM (standard deviation of the mean); control: distilled water; i.p. SD: CdCl2 intraperitoneal single dose; oral SD: CdCl2 oral single dose; oral FD: CdCl2 oral fractionated dose; TSI: tubulesomatic index; ESI: epithelium somatic index. abDifferent letters in the same row, for each evaluated time, indicate significant differences by the Student-Newman-Keuls test (p ≤ 0.05).
