Background: Immunotherapy is the only specific treatment for scorpion envenomation. In the present study, the protective effects of polyvalent antivenom against histopathological complications in kidneys and marker changes (BUN and creatinine) induced by Mesobuthus eupeus (Me) scorpion venom was investigated in anesthetized rabbits.
Methods: Twenty four rabbits were randomized into four groups: six rabbits in control group were received 1 ml distilled water subcutaneously (group 1). In group 2, sublethal dose of Me venom (4 mg/kg) was injected subcutaneously. Simultaneously venom (subcutaneously 1ml of an distilled water solution containing 4 mg/kg of Me venom) and antivenom (intravenously 5 ml) were administered in six rabbits as group 3 animals. In group 4, rabbits received five ml of antivenom, 60 min after Me venom injection.
Results: In group 2, venom injection caused histopathological damages such as glomerular congestion, dilated vessels of interstitium and focal interstitial congestion in the kidney. It also increased creatinine and BUN levels 3 h after envenomation. Simultaneous administration of antivenom and venom prevented histopathological damage and marker changes. In group four, Immunotherapy decreased histopathological damages and prevented creatinine and BUN elevation at 3 h.
Conclusion: Polyvalent antivenom administration can prevent and neutralize nephrotoxic effects of Mesobuthus eupeus scorpion envenomation, if used at optimum conditions.
