ameliorative effect of trevo dietary supplement against lead acetate nephrotoxicity

Background: trevo is a nutritional supplement with numerous bioactive natural products, with detoxifying and antioxidant properties. the purpose of this study was to investigate the ability of trévo to protect against oxidative stress induced by lead in the kidneys of male wistar rats. methods: thirty-five healthy male wistar rats were divided into five groups of seven rats each, using a randomized design. i=control; ii=15 mg/kg of lead acetate (pba); iii=2 ml/ kg of trevo+pba; iv=5 ml/kg of trevo+pba; v=5 ml/kg of trevo. animals were treated with trevo for five days before co-administration with lead intraperitoneally for 10 consecutive days. animals were sacrificed 24hr after the last administration, blood samples were collected via cardiac puncture, and processed for assessment of urea, creatinine, and uric acid (ua), while the kidney samples were excised and processed for the following biochemical assays: malondialdehyde (mda), glutathione-s-transferase (gst), catalase (cat), superoxide dismutase (sod), and reduced glutathione (gsh). results: injection of pba caused a significant increase in the serum levels of urea, creatinine, and uric acid, and a significant increase (p<0.001) in the mda concentration, and decreases in gsh concentration, cat, sod, and gst activities (p<0.05) as compared to the controls. pretreatment with trevo prevented the oxidative stress induced by lead acetate in the kidney tissue samples and improve the renal function. the protective effect was evident at 5 ml/kg of trevo. conclusion: the results showed that trevo was nephroprotective against lead toxicity and the activity might be linked to the presence of numerous antioxidant phytochemicals present in trevo.
