DEMONSTRATION OF DOPAMINE IMMUNOREACTIVITY IN OPEN AND CLOSED TYPE ENDOCRINE-CELLS OF GERBIL (MERIONES-UNGUICULATUS) STOMACH

Dopamine-immunoreactive cells were identified in the stomach of gerbil s using a selective antibody against glutaraldehyde-conjugated dopamin e In the pyloric area dopamine-containing cells were exclusively local ized in the basal part of the mucous membrane, whereas in the fundic a rea dopaminergic cells were seen throughout the basodistal extent of t he mucous membrane, Dopamine-containing cells belong to the class of c losed and open type endocrine cells and were found in the fundic area and in the pyloric area respectively. These findings are discussed alo ng with the likely modulatory function of dopamine in peripheral tissu es.
