چکیده

dendrobium genus was reported to contain alkaloid, bibenzyl, fluorenone, phenanthrene, sesquiterpenoid, and phenolic acid, which have biological properties. our aim was to investigate the protective effect of an aqueous extract of dendrobium nobile lindl (dne) against cisplatin-induced acute kidney injury (aki). quantification of four phenolic acids (4-hydroxybenzoic, vanillic, syringic, and ferulic acid) in dne was determined using the hplc-photodiode array method. possible protective effects against cisplatin-induced nephrotoxicity were investigated using in vitro (porcine kidney cells; pk15) and in vivo (sprague dawley rat) studies. among the four phenolic acids, 4-hydroxybenzoic acid was the most abundant. in the in vitro study, dne pretreatment partially prevented decrement of viability after cisplatin (15 μg/ml) treatment in the both the mtt and crystal violet assays. moreover, relative to cells treated with cisplatin alone, the dne (50 μg/ml)-pretreated cells showed a ~30% increase in glutathione levels and a ~15% decrease in reactive oxygen species. the expression of p53 was also decreased in dne-pretreated cells (p < 0.05). in the in vivo study, the renal function index decreased to normal levels in groups pretreated with dne (300 and 500 mg/kg); histopathological alterations and apoptotic cells were also attenuated. moreover, dne pretreatment ameliorated oxidative stress in the kidney, as evidenced by recovered antioxidant enzyme levels and decreased lipid peroxidation. dne, by decreasing oxidative stress, was found to have a protective effect against cisplatin-induced nephrotoxicity. based on these findings, dne might be beneficial when treating cisplatin-induced aki.

Protective Effect of P-Coumaric Acid against Cisplatin-Induced Nephrotoxicity and Hepatotoxicity in Rats

Background and purpose: Cisplatin is used in chemotherapy for cancer patients. But, it has adverse effects on some organs, including the kidney and liver. P-coumaric acid is a polyphenolic substance with multiple biological properties. The present study aimed to investigate the effect of p-coumaric acid on renal and hepatic side effects of cisplatin. Materials and methods: This experimental st...

Protective Effects of Verapamil Against Hexachlorobutadiene Nephrotoxicity in Rat

Background: Hexachlorobutadiene (HCBD), a potent nephrotoxin can cause degeneration and necrosis in renal tubular epithelial cells in rodents. Its toxicity is due to conjugation with glutathione to form the related cysteine conjugate. This metabolite is then taken up by the kidney and cleared through renal tubular epithelial cells as a reactive thiol derivative by the enzyme β-lyase. Objective:...

Protective effects of madecassoside against Doxorubicin induced nephrotoxicity in vivo and in vitro

Madecassoside (MA), a triterpenoid saponin isolated from C. asitica, exerts various pharmacological activity including antioxidative and antinflammatory. Doxorubicin (DOX), a common chemotherapeutic drug, has been reported to induce numerous toxic side effects including renal-toxicity. We hypothesized that MA administration may decrease renal-toxicity caused by DOX. In this study, we investigat...

The protective effect of Nigella sativa against cisplatin-induced nephrotoxicity in rats

Objective: The clinical use of cisplatin is highly restricted, because of its nephrotoxicity.In this study the protective effect of Nigella sativa (N. sativa) against cisplatin-induced nephrotoxicity was investigated in rats. Materials and Methods: In the current study, the effects of the administration of aqueous-ethanolic extract of N. sativa (100 and 200 mg/kg, BW) and vitamin E (100 mg/kg, ...
