Abstract

Mesobuthus eupeus is an indigenous Scorpion species in Southwest Iran which is responsible for the majority of Scorpion sting cases in Khuzestan province. To conduct this research a total of 75 Wistar male rats were divided into 5 equal groups randomly. Group 1 (control); Group 2: M. eupeus venom was administered with a dose of 1 mg/kg IP. Group 3: Venom + 0. 5 ml of polyvalent Antivenom intramuscularly, 30 minutes after envenomation. Group 4: Venom + 5 mg/kg of Carvedilol 30 minutes after envenomation IP. Group 5: Venom + 0. 5 ml of polyvalent Antivenom + 5 mg/kg of Carvedilol 30 minutes after envenomation IP. Blood samples were collected by cardiac puncture at 8, 24, and 48 hours after saline/venom injection from anesthetized rats. Heparinized plasma was isolated to measure cardio-related biochemical parameters, including the activity of CPK, LDH, and AST and troponin-I levels were measured by routine methods. The results showed that the activity of the enzymes of CPKMB, LDH, AST, and also troponin-I as a specific index of heart damage elevated at different times following venom injection compared with the control group. Even though the administration of anti-venom following venom injection at different times significantly reduced the activity of these enzymes and also troponin-I levels, but the level of these indicators was still higher than the control group. Carvedilol administration had no significant effect on reducing the activity of the above-mentioned factors. Meanwhile, the combined administration of Carvedilol and anti-venom following venom injection had similar results with the Antivenom group. This result may relate to the dose and its frequency of Carvedilol use.
