Immune histochemical-stained sections for P53 in the renal cortex of albino rats in the study groups. P53 nuclear immune reactions (p). a Control group, reaction appears in few cells. b DN group, showing the reaction in many cells. c DN + ZnO-NPs groups, showing the reaction in some cells. d The average count of brown nuclei in anti-p53 immune-stained sections. Estimates are displayed as mean ± standard errors (X ± SEM); ^a: P compared to control group; ^b: P compared to DN group; ^#: P< .05; ^##: P< .001.
