title: Wen-pi-tang-Hab-Wu-ling-san attenuates kidney ischemia/reperfusion injury in mice. A role for antioxidant enzymes and heat-shock proteins.
abstract: The purpose of this study was to investigate the effects of Wen-pi-tang-Hab-Wu-ling-san (WHW) extract, which has been used for treatment of renal diseases, on kidney ischemia/reperfusion (I/R) injury. Thirty minutes of bilateral renal ischemia resulted in disruption of kidney tubular epithelial cells and increased plasma creatinine levels in mice, however these effects were significantly attenuated when WHW was administered prior to I/R. WHW-administration also inhibited post-ischemic decreases of catalase, copper-zinc superoxide dismutase (CuZnSOD), and manganese superoxide dismutase (MnSOD) activity in kidney tissue, leading to decreased tissue hydrogen peroxide levels and lipid peroxidation. Post-ischemic increases of heat-shock protein (HSP)-27 and -72 expressions were greater in mouse kidneys that received WHW. In conclusion, WHW-administration reduced kidney susceptibility to I/R injury, and this reduced susceptibility was associated with greater post-ischemic activation of catalase, CuZnSOD and MnSOD, resulting in reduced hydrogen peroxide levels and lipid peroxidation, as well as higher post-ischemic expression of HSP-27 and -72.
