Abstract

We examined the basic pharmacology of abalone gut tissues for adrenergic and peptide receptors using ligand binding and by determining the pharmacological effectors of abalone gut motility in a number of gut regions. Contractile responses could not be elicited, even though we could show the existence of α-adrenergic and peptide receptors. Responses to any muscle contractile agents, including carbachol and potassium chloride, could not be found in blacklip abalone, Haliotis rubra (Leach). Histology confirmed the relative absence of muscular layers in all the tissues of the gut, indicating that previous literature reports of muscular involvement in contractile movement of gut contents did not appear to apply to this species.
