Abstract

ABSTRACT: Cisplatin (CP) is an antineoplastic drug; however, owing to its nephrotoxicity, its clinical use is limited. We investigated whether vitexilactone (vitex) is a safe and effective treatment for CP induced kidney injury. We allocated Sprague-Dawley rats into six groups: control group, low dose-high dose vitex groups (40 and 80 mg/kg vitex for 6 days before administration of CP), CP group (single 6 mg/kg dose on day 6) and CP + low dose vitex-CP + high dose vitex group (40 and 80 mg/kg vitex for 6 days, and a single 6 mg/kg dose of CP on day 6. Rats were euthanized 5 days after CP treatment. After exposure to CP and/or vitex, total oxidative stress and total antioxidant status were assessed. The histology of the kidney was examined using hematoxylin and eosin, and periodic acid-Schiff. We used immunohistochemical and fluorescence staining to detect expression of caspase-3. We also measured blood urea nitrogen, uric acid and creatinine levels. Nephroprotective effects of vitex were associated with decreased serum toxicity markers and increased antioxidant activity. Vitex also reduced the expression of the apoptosis marker, caspase-3. Treatment with CP increased blood urea nitrogen, uric acid, creatinine levels and total antioxidant status, and decreased total antioxidant status compared to the control group. Use of vitex for protection from CP induced nephrotoxicity appears to be a safe and efficacious alternative for treatment of kidney injury.
