Black widow spider bite.
These two cases illustrate many classical features of latrodectism. A subclinical bite followed by extensive systemic signs and symptoms in a recognizable pattern is strongly suggestive of the diagnosis. Pain and muscle spasms are refractory to standard therapy but are relieved by intravenous calcium. Finally, there should be complete resolution of the symptoms after only one vial of antivenin ...
متن کاملReversibility and mode of action of Black Widow spider venom on the vertebrate neuromuscular junction
Black widow spider venom (BWSV) stimulates transmitter release and depletes synaptic vesicles from muscles bathed in a sodium free medium containing 1 mM EGTA. However, frog neuromuscular junctions treated with BWSV in glucosamine Ringer's and post-treated with antivenin recover normal function. This suggests that probably the permanent block of neuromuscular transmission is due to changes in p...
متن کاملEffects of Black Widow Spider Venom and Ca" on Quantal Secretion at the Frog Neuromuscular Junction
A modification of the classical procedure of fluctuation analysis is used to measure the waveform, w(t), mean amplitude, (h), and mean rate of occurrence, (r), of miniature endplate potentials (MEPPs) at frog cutaneous pectoris neuromuscular junctions treated with black widow spider venom (BWSV) . MEPP parameters are determined from the power spectrum of the fluctuating potential and the second...
