The distribution of the calcium binding protein neurocalcin a has been examined in the enteric nervous system of young adult (3 months) and aged (24+ months) male rats by immunofluorescence. Neurocalcin-immunoreactive (NC-ir) neurons were observed in the submucous and myenteric plexuses throughout the gastrointestinal tract from the oesophagus to the distal large intestine. NC-ir nerve terminals were also seen on NC-ir and NC-negative neurons. Semiquantitative estimates revealed fewer NC-ir neurons in the submucous plexus than in the myenteric plexus. The greatest occurrence of NC-ir neurons was in the small and large intestine. NC-ir axons were seen in the mucosa and also in between the ganglia of the myenteric plexus. In the aged rats, there were no discernible changes in the numbers of NC-ir neurons in th e oesophagus and stomach, with an increase in the pylorus and slight decreases in the small and large intestines. No decrease in NC-ir was observed in the distal large intestine. NC-ir neurons never contained lipofuscin age pigment and many enteric neuro ns devoid of NC-ir contained age pigment. Like other previously investigated calcium-binding proteins in enteric neurons, the distribution of NC shows much variability from one part of the intestine to another. The observed slight decreases in the number of NC-ir enteric neurons in aged rats may compromise the regulation of calcium in these neurons.
