摘要：Gentamicin is an effective antibiotic that has been used worldwide for many years. While considered an essential medicine by the WHO, gentamicin can also lead to severe kidney damage. This study explored the ameliorative effects of Glycyrrhiza glabra root extract on gentamicin‐induced renal injury in mice. Four groups of n = 7 mice were used: (a) control; (b) G. glabra‐only; (c) gentamicin‐only; and (d) gentamicin plus G. glabra. Kidney samples were tested for: antioxidant enzyme activity (superoxide dismutase [SOD] and glutathione peroxidase [Gpx]); expression of HO‐1 and nuclear factor erythroid 2‐related factor 2 genes; expression of Cox‐2 and Bax; cytokine levels (IL‐1β, and IL‐6); histopathological anomalies; and standard renal functional component levels (creatinine, urea, and blood urea nitrogen). The effects of gentamicin were generally reversed or normalized following treatment with G. glabra root extract. Gentamicin decreased Gpx and SOD parameters and increased IL‐1 β and IL‐6 levels, but these returned to normal in the G. glabra‐treated group. Gentamicin upregulated tissue levels of Cox‐2 and Bax, and downregulated HO‐1 and Nrf‐2 expression but again, and these levels returned to normal in the group treated with G. glabra. Mice that had received gentamicin exhibited acute renal blood vessel congestion, focal interstitial round cell aggregation, and hydropic degeneration of renal tubular epithelium. However, those that had also received G. glabra showed a normal histopathology. Findings from this study indicate that in mouse models, gentamicin‐induced kidney damage can be reversed or ameliorated by administering G. glabra, so it can be considered as an effective complimentary therapy.
