Example sentences for: venoms
How can you use “venoms” in a sentence? Here are some example sentences to help you improve your vocabulary:
In Trinidad the following clinical features have been seen: tachypnea, restlessness, vomiting, increased salivation, cerebral oedema, pulmonary oedema, hypovolemic shock and convulsions, with myocarditis and pancreatitis being major complications [ 48 ] . Scorpion venoms may cause these symptoms through release of catecholamines from the sympathetic nervous system [ 11 ] . The venom exerts its effects primarily to the cardiovascular and respiratory systems, but there is also stimulation of both the sympathetic and parasympathetic peripheral activities [ 11 ] . The venom is a complex mixture of phospholipase A 2 , low molecular weight proteins, acetylcholinesterase, hyaluronidase, toxic polypeptides, amino acids, serotonin and neurotoxins [ 11 48 ] . Two fatal cases suggested toxic myocarditis [ 48 ] .
Unfortunately no research on the venoms of Trinidad's snakes was discovered so the following review is of the closely related South American and Caribbean snakes and scorpions.
The in vitro myotoxicity of the crotalid venoms venoms ( Bothrops jararaca , Bothrops jararacussu and Lachesis muta ) and myotoxins (bothropstoxin, bothropasin and crotoxin) was neutralised by simultaneous exposure of isolated skeletal muscles to an aqueous extract of Eclipta prostrata or to wedelolactone, stigmaterol and sitosterol.
Ethanolic extracts of the aerial parts of Eclipta prostrata (Asteraceae) neutralised the lethal activity of the venom of South American rattlesnake ( Crotalus durissus terrificus ), as well as the myotoxic and haemorrhagic effects of B. jararaca , B. jararacussu and Lachesis muta snake venoms when mixed in vitro before i.p.
These compounds may have played a role in the inhibitory effect observed, probably owing to the chelation of the zinc required for the catalytic activity of venom's haemorrhagic metalloproteinases [ 45 ] . Reduction in the intensity of the effects of envenomation could also be achieved by a neutralisation of the venom peptides, polypeptides, proteins and enzymes [ 38 11 ] . There are plants used for snakebite that act by inhibiting the proteolytic activities of the venom and antagonising crotoxin-induced haemolysis, myotoxic and haemorrhagic activities of crotalid venoms [ 46 ] .
