Dexmedetomidine Pretreatment Attenuates Kidney Injury and Oxidative Stress during Orthotopic Autologous Liver Transplantation in Rats

Figure 4

The expression of Nrf2 in kidney tissues of different groups was detected by immunofluorescence staining under a laser scanning confocal microscope (magnification 400x). (a) Group S; (b) group M; (c) group D1; (d) group D2; (e) group B1; (f) group B2; and (g) group B3. Positive Nrf2 cells were stained green, with the sections counterstained with 4,6-diamidino-2-phenylindole (DAPI) to visualize nuclei. Arrows indicate Nrf2 positive glomerular cells, while the triangle points at Nrf2 positive tubular epithelial cells.
