Anticholinesterase activity of elapid venoms
Toxicon, 1973Abstract Of 16 elapid venoms from Naja, Bungarus, Ophiophagus, Dendroaspis, Hemachatus and Notechis species, only Notechis scutatus venom totally lacked anticholinesterase activity while N. nigricollis, M. fulvius, D. jamesoni, D. polylepis and D. angusticeps lacked acetylcholinesterase activity.

Isoenzymes of elapid acetylcholinesterases
Comparative Biochemistry and Physiology Part C: Comparative Pharmacology, 1977Abstract 1. Acetylcholinesterase activity of Naja naja naja, Naja melanoleuca and Bungarus fasciatus venoms is due to mixtures of isoenzymes. 2. Naja melanoleuca venom has two acetylcholinesterase isozymes and both Naja naja naja and Bungarus fasciatus venoms have four acetylcholinesterase isozymes that are resolved by disc gel ...

Clinical implications of convergent procoagulant toxicity and differential antivenom efficacy in Australian elapid snake venoms [PDF]
Toxicology Letters, 2019 Australian elapid snakes are some of the most venomous snakes in the world and are unique among venomous snakes in having mutated forms of the blood clotting factor X in an activated form (FXa) as a key venom component. In human bite victims, an overdose

Comparative studies on Egyptian elapid venoms
Zeitschrift für Ernährungswissenschaft, 1980The immunological properties of Naja haje from Western Desert, Naja haje of the Nile Delta, Naja nigricollis from Upper Egypt and Walternnesia aegyptia from Sinai Desert were compared using horse serum antivenin prepared from the Delta Naja haje venom. All elapid venoms showed very similar precipitin lines with immunodiffusion or immunoelectrophoresis ...

Species differences in susceptibility to elapid venoms
Toxicon, 1969Birds (pigeon, chick and Formosan sharp-tailed munia) are extremely susceptible to the lethal action of the venom of Bungarus multicinctus as compared with mammals. Comparison of the neuromuscular blocking activity of α- and β-bungarotoxin in chick's biventer cervicis muscle reveals that avian muscle is particularly susceptible to β- but not to α ...

Elapid snakebite as a cause of severe hypertension
The Journal of Emergency Medicine, 2006Snakebite is a common medical emergency in tropical countries, however, autonomic dysfunction is an uncommon manifestation of snakebite. The authors present an unusual manifestation of severe neurotoxic snake envenomation: severe hypertension requiring intravenous antihypertensives.

Acetylcholinesterase in Elapid Snakes
1998Acetylcholinesterase (AChE) plays a key role in cholinergic transmission, but is also present in non-cholinergic contexts where its function is not clearly known (1). This is the case in pulmonary and intestinal epitheliums, salivary glands, or blood cells surface. AChE is a very abundant protein in the venom of some Elapids snakes (2–3).

Rationalisation of First-Aid Measures for Elapid Snakebite
Wilderness & Environmental Medicine, 1979The plasma of monkeys envenomated with tiger snake (Notechis scutatus) venom was monitored by radioimmunoassay for both crude venom and a neurotoxin. When the injected limb was immobilised and a pressure of 55 mm Hg applied to the injection site, only very low levels of circulating venom or neurotoxin were detectable. In practical terms, venom movement

Prey transport in “palatine‐erecting” elapid snakes
Journal of Morphology, 2003AbstractCobras and mambas are members of a group of elapid snakes supposedly united by the morphology and inferred behavior of their palatine bone during prey transport (palatine erectors). The palatine erectors investigated (Dendroaspis polylepis, Naja pallida, Ophiophagus hannah, Aspidelaps scutatus, A. lubricus) show differences in the morphology of
