In the neurotomised animals, venom-induced mean arterial pressure (MAP) and respiratory rate (RR) changes were markedly attenuated but not the heart rate (HR) changes indicating the existence of additional afferent pathway. Hence, further sets of experiments were performed to explore the afferents. Albino rats were anaesthetised with an intra-peritoneal injection of urethane (1.5 g/kg). Tracheo...
Spider venoms are complex cocktails rich in peptides, proteins and organic molecules that collectively act to immobilize prey. Venoms of the primitive hunting spider, Plectreurys tristis, have numerous neurotoxic peptides called "plectoxins" (PLTX), a unique acylpolyamine called bis(agmatine)oxalamide, and larger unidentified protein components. These spiders also have unconventional multi-lobe...
Scorpion stings are very frequent in Tunisia; yet a method for evaluating envenoming severity and consequently victim treatment, has never been adequately established nor has its efficiency been properly evaluated. Indeed, a management of envenomed patients requires the optimization of envenoming antivenom immunotherapy. This task requires either, an accurate evaluation of toxicokinetic paramet...
Stings from scorpions (Buthus tamulus) produce acute myocarditis and can result in death in children and adults. Acute myocarditis was induced in anaesthetised dogs by intravenous injection of 4 mg/kg venom (Buthus tamulus). Myocarditis was confirmed by ECG. Blood was collected before and 30 minutes after venom treatment and processed for osmotic fragility. An increase in osmotic fragility of r...
The potassium channel Kv 1.3 plays a vital part in the activation of T lymphocytes and is an attractive pharmacological target for autoimmune diseases. BmP02, a 28-residue peptide isolated from Chinese scorpion (Buthus martensi Karsch) venom, is a potent and selective Kv1.3 channel blocker. However, the mechanism through which BmP02 recognizes and inhibits the Kv1.3 channel is still unclear. In...
