Abstract:

The aim of the present study was to investigate the protective role of royal jelly (RJ) and green tea (GT) extracts on cisplatin (cDDP)-induced nephrotoxicity in adult albino mice. Albino mice were randomly divided into six groups: Group I (control) received a single intraperitoneal injection of isotonic saline (0.02 mL/g), Group II received a single intraperitoneal injection of cDDP (7 mg/kg of body weight), Group III received RJ (100 mg/kg of body weight), Group IV received GT (100 mg/kg of body weight), Group V received RJ (100 mg/kg of body weight) + cDDP (7 mg/kg of body weight), and Group VI received GT (100 mg/kg of body weight) + cDDP (7 mg/kg of body weight). The concentrations of blood urea nitrogen (BUN) and creatinine were evaluated. In addition, kidney samples were taken for determination of tissue malondialdehyde (MDA) and reduced glutathione (GSH) levels. In addition, histopathological changes in kidneys were investigated. The results indicated that no significant differences in MDA, GSH, BUN, and creatinine levels were observed among the control group and groups treated with RJ alone and GT alone (P>.05). However, there was a significant increase in BUN and creatinine parameters after cDDP application in Groups II, V, and VI. The mice treated with only cDDP exhibited an increase in serum BUN and creatinine levels when compared to Groups V and VI (P<.05). Moreover, cDDP-induced oxidative damage caused a significant decrease in GSH levels and a significant increase in MDA levels in kidneys (P<.05). RJ and GT supplementation attenuated cDDP-induced nephrotoxicity, which was manifested by stopping the elevation in serum creatinine and BUN levels. Moreover, RJ and GT supplementation restored GSH content and MDA production levels in the kidney tissue following cDDP treatment (P<.05). These products were also effective in protecting against cDDP-induced tissue damage in mouse kidneys. In conclusion, 100 mg/kg of body weight doses of RJ and GT provided protection against cDDP-induced nephrotoxicity, and both products can act as protector agents against cDDP-induced kidney damages.
