Fucoidans (FUC) are organic sulfated polysaccharides from natural seaweeds with multiple biological actions. The current study was performed to assess the chemoprotective, antioxidant, and anti-inflammatory effects of FUC from Laminaria japonicum against diazinon (DZN)-induced injuries to rat cardiac, hepatic, and renal tissues. Forty male Wistar rats were assigned into five groups, receiving saline, oral FUC 200 mg/kg/day, subcutaneous DZN 20 mg/kg/day, DZN plus FUC 100 mg/kg/day, or DZN plus FUC 200 mg/kg/day (each treatment was given daily for 4 weeks). Data analysis showed that DZN-intoxicated rats exhibited significantly higher (p < 0.05) serum levels of alanine transaminase, aspartate transaminase, alkaline phosphatase, urea, creatine, creatine kinase, creatine kinase-MB, lactate dehydrogenase, cholesterol, interleukin-6, and tumor necrosis factor-α, as well as lower levels of acetylcholinesterase, compared to control rats. In addition, DZN intoxication was associated with significantly higher (p < 0.05) cardiac, hepatic, and renal tissue concentrations of malondialdehyde and nitric oxide, as well as lower glutathione concentrations, and activities of glutathione peroxidase, superoxide dismutase, and catalase enzymes in comparison to control rats. Treatment with FUC (at 100 or 200 mg/kg/day) ameliorated all the aforementioned alterations in a dose-dependent manner. In conclusion, FUC from Laminaria japonicum ameliorated DZN-induced oxidative stress, pro-inflammatory effects, and injuries to the cardiac, hepatic, and renal tissues. These effects may be related to the antioxidant and anti-inflammatory effects of FUC.
