Methanolic extract of Rhinella schneideri (cururú toad) poison crude cause ultrastructural changes in nerve terminals of mouse phrenic nerve-diaphragm preparations
Abstract:Rhinella schneideri (or Bufo paracnemis), popularly known in Brazil as cururu toad, is also found in other countries in South America. The cardiovascular effects of this poison are largely known and recently was shown that it is capable to affect the neuromuscular junction on avian and mice isolated preparation. In this work, we used transmission electron microscopy to investigate the ultrastructure of the motor nerve terminal and postsynaptic junctional folds of phrenic nerve-hemidiaphragm preparations incuba… Show more
