Abstract
1 The presynaptic cardio-inhibitory and postsynaptic pressor responses to the α-adrenoceptor agonists xylazine and cirazoline, and the interaction with the antagonists yohimbine and prazosin, were examined in the pithed rat.
2 Evidence was found to suggest that, as well as the already established pre- and postsynaptic α2- and postsynaptic α1-receptors, presynaptic α1-receptors are present.
