Organ toxicity attenuation by nanomicelles containing curcuminoids: Comparing the protective effects on tissues oxidative damage induced by diazinon

Objective(s): Diazinon (DZ) is an organophosphate pesticide that induces oxidative damage in different organs. The aim of this study was to compare the effectiveness of nanomicelles containing curcuminoids (NCUR) and natural curcumin (CUR) in attenuating the oxidative damage induced by DZ in male rats. Materials and Methods: After a single intraperitoneal (IP) injection of DZ (100 mg/kg), the rats were administered either CUR or NCUR (25 and 60 mg/kg, IP). Biomarkers of cell damage including, alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), creatinine (Cr), urea, lactate dehydrogenase (LDH), creatine kinase-MB isoenzyme (CK-MB) and troponin I, were quantified in the serum. Lipid peroxidation (LPO) and glutathione (GSH) content in the liver, kidney, and heart tissues were determined. Results: DZ administration increased the serum levels of ALT, AST, ALP, Cr, urea, LDH, CK-MB, and troponin I; however, the levels significantly (P
