Renal failure is a disease that until now has no cure. Renal replacement therapy, such as dialysis and transplantation, may inhibit the disease’s progression. However, they require a relatively high cost. Therefore, in the process of therapy, it is required to utilize the cheaper alternative therapies which are derived from traditional medicine that are capable to inhibit the development of renal failure. In this regard, this present study was conducted to evaluate the effect of ethanol extract of corn silk (Zea mays L.), binahong (Anredera cordifolia), and its combination against gentamicin-piroxicam induced nephrotoxicity because both corn silk and binahong have already known to have antirenal failure activity in its single use. The use of gentamicin (100 mg/kg bw; intraperitoneally) and piroxicam (3.6 mg/kg bw; orally) combination for seven days has been proved to establish a rat model of renal failure. Extract (75 mg/kg bw for corn silk and 100 mg/kg bw for binahong; orally) was given each day for four weeks since the 8th day. Evaluation of renal function was performed by measuring serum creatinine levels, renal oxidative stress, and renal histology.

Treatment with Zea mays L. and Anredera cordifolia, and its combination extract significantly restored renal function which illustrated by serum creatinine levels. It also reduced lipid peroxidation and enhanced SOD and catalase activities. Histological found similar results which showed improvement in renal cells after administration of the extract compared to the group which was not given extract. However, the application of combination extract did not give any superior effect. By using rat model, Zea mays L., Anredera cordifolia and its combination extract provided improvement against renal toxic effect of gentamicin-piroxicam.
