This study investigates the concerted hepatoprotective effects for three doses of bradykinin potentiating factor (BPF) and/or followed by exposure to a low dose of γ-radiation (LDR) against  Naja haje  envenoming in rats. Male rats were injected with three consecutive doses of BPF (1 μg/g i.p. for 3 days), followed by exposure to a low dose of gamma radiation (0.5 Gy), and then rats were injected with a dose of  Naja haje  venom (250 μg/kg i.p.). Results showed that  Naja haje  causes liver damage, significant elevation of alanine aminotransferase (ALT), aspartate aminotransferase (AST), alkaline phosphatase (ALP), cytochrome c, Nitric oxide (NO), malondialdehyde (MDA) and significant depletion in glutathione peroxidase (GPx) contents. In addition, significant depletion in B-cell lymphoma 2 (Bcl-2) and significant elevation in BcL-2 associated X (Bax protein), nuclear factor kappa B (NF-κB), interleukin-1β (IL-1β) in hepatocytes. Bradykinin potentiating factor and/or low dose of γ-radiation caused improvement in liver damage caused by  Naja haje  venom by a significant decrease in ALT, AST, ALP levels, Bax, cytochrome c, NF-κB, IL-1β, NO and MDA contents, BPF alone or combined with low dose radiation caused a significant increase in Bcl2 and GPx contents. In conclusion, the concerted impact of BPF and LDR may provide an effective venom detoxification tool that helps to reduce hepatic toxicity and extends the lifespan.
