Abstract
Aflatoxins are a common food contaminant of global concern. Aflatoxin B1 (AFB1) intoxication is associated with
serious health hazards. Recently, fucoidan (FUC) has gained much attention from pharmaceutical industry due to
its promising therapeutic effects. The impacts of FUC on AFB1-induced liver and kidney injures have not been sufficiently
addressed. This research was conducted to evaluate the ameliorative effect of FUC in AFB1-induced hepatorenal
toxicity model in rats over 14 days. Five groups were assigned; control, FUC (200 mg/kg/day, orally),
AFB1 (50 μg/kg, i.p.), and AFB1 plus a low or high dose of FUC. AFB1 induced marked hepatorenal injury elucidated
by substantial alterations in biochemical tests and histological pictures. The oxidative distress instigated
by AFB1 enhanced production of malondialdehyde (MDA) and nitric oxide (NO) along with reduction in the reduced-
glutathione (GSH), glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), and catalase (CAT) activities.
DNA damage in the liver and kidney tissues has been demonstrated by overexpression of proliferating
cell nuclear antigen (PCNA). Unambiguously, FUC consumption alleviates the AFB1-induced mitochondrial dysfunction,
oxidative harm, and apoptosis. These ameliorated effects are proposed to be attributed to fucoidan's
antioxidant and anti-apoptotic activities. Our results recommend FUC supplementation to food because it exerts
both preventive and therapeutic effects against AFB1-induced toxicity.
