In this study, the effects of sublethal dose of Androctonus australis hector (Aah) venom on the enzymatic activities (creatine phospho-kinase and lactate dehydrogenase) and histopathological changes of heart and lungs' organs were determined 24h following envenoming NMRI mice. The effects of Aah venom on the lytic activity of the complement system, plasma(More)
Recombinant antibody fragments consisting of variable domains can be easily produced in various host cells, but there is no universal system that can be used to purify and detect them in the free form or complexed with their antigen. Protein L (PpL) is a cell wall protein isolated from Peptostreptococcus magnus, which has been reported to interact with the(More)
Release and activation of pro-inflammatory mediators are among the most important induced factors that are involved in the scorpion envenomation pathogenesis. Inflammatory response and lung reactivity were studied in mice following subcutaneous injection with Androctonus australis hector (Aah) venom. Venom immunodetection in lungs and sequestered cell(More)
Previous works had shown that scorpion venom induced neurotransmitter elevation and an inflammatory response associated with various anatomo-pathological modifications. The most dangerous scorpions species in Algeria responsible for these effects are Androctonus australis hector (Aah) and Androctonus amoreuxi (Aam). Comparison of the physiopathological(More)
The inflammatory response caused by scorpion venoms is a key event in the pathogenesis of scorpion envenomation. This response was assessed in the cardiac, pulmonary, and gastric tissues of envenomed mice. The results reveal an increase of permeability in cardiac, pulmonary, and gastric vessels accompanied by an edema-forming, inflammatory cell(More)
Scorpion stings are mainly associated with cardiovascular disturbances that may be the cause of death. In this study, the involvement of angiotensin II (Ang II) in cardiac and aortic inflammatory response was studied. Mice were injected with Androctonus australis hector (Aah) scorpion venom (0.5mg/kg, subcutaneously), in the presence or absence of an(More)
Scorpion venoms are known to cause different inflammatory disorders through complex mechanisms in various tissues. In the study here, the involvement of phospholipase A2 (PLA2) and cyclo-oxygenase (COX)-derived metabolites in hepatic and renal inflammation responses were examined. Mice were envenomed with Androctonus australis hector scorpion venom in the(More)
