title: Localization of atrial natriuretic peptide/cardiodilatin (ANP/CDD)-immunoreactivity in the lacrimal gland of the domestic pig.
abstract: The presence of atrial natriuretic peptic/cardiodilatin-immunoreactive material was demonstrated in the lacrimal gland of the domestic pig by high performance liquid chromatography and radioimmunoassay. The immunohistochemical localization revealed a distinct population of cuboid or spindle-shaped ANP/CDD-IR cells in the epithelium of the terminal portion of the secretory tubules. In addition, a moderate number of positive cells was localized intraepithelially in the intralobular ducts as well as the connective tissue between these ducts. Our findings provide a morphological indication that ANP/CDD may play a physiological role in the regulation of sodium transport and secretion in the lacrimal gland.
