Results of histopathological examination. (a) Kidney of control group showing normal glomeruli (arrow) and tubules (*). (b) Kidney of Glycyrrhiza glabra group showing normal histology of both glomeruli (arrows) and tubules (*). (c–e) Kidney of gentamicin group: (c) Extensive coagulative necrosis of renal tubules was detected (*) with numerous pyknotic nuclei (arrow). (d) Severe congestion of renal blood vessels (arrows) along with hydropic degeneration of renal epithelium (*) were detected. (e) Arrow showed interstitial round cell infiltration. (f) Gentamicin + Glycyrrhiza glabra group showed restoration of normal glomerular (arrow) and tubular (*) architecture. Scale bar = 50 μm
