Histopathological assessment of rat kidney tissue after treatment with vancomycin (VAN) alone, piperacillin/tazobactam (TZP) alone or TZP in combination with VAN (VAN+TZP). (a) Quantitative analysis of histopathology score in kidney tissues of rats. Values are expressed as mean ± SD; *P < 0.044 versus saline. Representative photomicrographs of haematoxylin and eosin-stained rat kidney sections. (b) Normal histology of kidney tissue in control rats administered normal saline, (c) tubular casts (arrow, ×100) in cortex of rats treated with TZP 1400 mg/kg IP once daily for 3 days, (d) tubular dilatation, tubular degeneration (arrows) and tubular basophilia (asterisk, ×100) in cortex of rats treated with VAN 150 mg/kg IV once daily for 3 days, and (e) tubular dilatation, tubular degeneration (arrows, ×100) in cortex of rats treated with VAN+TZP once daily for 3 days. This figure appears in colour in the online version of JAC and in black and white in the printed version of JAC.
