title: Receptor mechanisms in vasoconstrictor responses to choline esters in Bufo melanostictus.
abstract: Choline esters have been found to cause vasoconstriction of perfused systemic blood vessels of common Indian toad, Bufo melanostictus. The vasoconstriction appears to be mediated through atropine sensitive receptors and nicotinic mechanisms appear unlikely to be involved.
