Abstract:

Scorpion envenomation is a main general health problem in developing countries, especially in tropical and subtropical regions. Hemiscorpius lepturus as a member of the Hemiscorpiidae family is cause of the most scorpion sting lethality in Iran. In the present study, the oxidative stress and antioxidant defense in serum of envenomated sheep with the venom of Hemiscorpius lepturus were investigated. Nine sheep were randomly divided into three groups (three in each). Groups A, B and C received 0.10, 0.05 and 0.01 mg kg-1 of H. lepturus venom subcutaneously, respectively. Blood sampling were performed 30 min before envenomation (control) and 30 min, 1, 2, 3 and 6 hr after envenomation and serum levels of total antioxidant capacity (TAC), malonedialdehyde (MDA) and protein carbonyl (PCO) were determined. The TAC was significantly increased at the doses of 0.10 mg kg-1 (at 3 hr) and 0.05 mg kg-1 (at 6 hr) compared to pre-injection time. However, no significant differences were observed in serum levels of MDA and PCO in different groups. It can be concluded that the dose of 0.01 mg kg-1 of venom had no effect on stress factors of serum, but according to increased level of TAC at the doses of 0.05 and 0.10 and no significant changes in serum levels of MDA and PCO, the oxidative damage has been prevented by the antioxidant defense system response.

Toxic Effects of Scorpion, Hemiscorpius Lepturus (hemiscorpiidae) Venom on Mice

Scorpion stings are common in Iran, particularly in the southern and southwest regions of the country, and they pose a serious health problem. Hemiscorpius lepturus is the most venomous scorpion in the region. The present study was conducted to investigate the in vivo effects of scorpion venom in experimental mice. Haematological parameters (white and red blood cells numbers and haematocrit lev...

Cardiotoxic Effects of Hemiscorpius lepturus Scorpion Venom Fractions in Rats

Background: Scorpion stings are responsible for many deaths in humans; however, the toxicity mechanisms of the venoms from many species are not well studied. We investigated the cardiotoxicity of the crude venom from H. lepturus scorpion and its isolated fractions, F-I to F-VI. Methods: The scorpion’s venom was extracted into six fractions by chromotagraphy. Healthy male Wistar rats (N=72) wer...

Enzymatic analysis of Hemiscorpius lepturus scorpion venom using zymography and venom-specific antivenin.

Hemiscorpius lepturus envenomation exhibits various pathological changes in the affected tissues, including skin, blood cells, cardiovascular and central nervous systems. The enzymatic activity and protein component of the venom have not been described previously. In the present study, the electrophoretic profile of H. lepturus venom was determined by SDS-PAGE (12 and 15%), resulting in major p...

The pharmacokinetics of Hemiscorpius lepturus scorpion venom and Razi antivenom following intramuscular administration in rat

Hemiscorpius lepturus (H. lepturus) is one of the most dangerous scorpions in Iran. Intramuscular administration (IM) of available Razi antivenom to H. lepturus venom is used by many of Iranian clinicians. The purpose of the current study was to investigate the efficiency of IM route for treatment of envenomed patients by H. lepturus. We compared the pharmacokinetics parameters of venom and ant...

A biodistribution study of Hemiscorpius lepturus scorpion venom and available polyclonal antivenom in rats

The purpose of the present study was to investigate the biodistribution profile of the venom of Hemiscorpius lepturus, the most dangerous scorpion in Iran. Blood and tissue samples were taken at various predetermined intervals during a 400-minute period for the venom and a 360-minute period for the antivenom in rats. The radio-iodination was carried out using the chloramine-T method. The result...

Cardiotoxic and Arrhythmogenic Effects of Hemiscorpius lepturus Scorpion Venom in Rats

BACKGROUND Envenomation by Hemiscorpius lepturus is not painful and the clinical manifestations include bloody urine due to hemoglobinuria or hematuria, dermonecrotic reactions, cardiac arrhythmia and in minority of cases acute renal failure which may lead to death following disseminated intravascular coagulation in infants. Cardiac effects of envenomation by H. lepturus venom including inotrop...
