Comparative data on acetylcholinesterase cytochemistry in various chromaffin cell types of Discoglossus pictus (Amphibia, Anura).
The cytochemical localization of acetylcholinesterase (AChE) activity was studied in the adrenal chromaffin cells of Discoglossus pictus. Reaction end-products were associated with all types of chromaffin cells, i.e. adrenaline (A), noradrenaline (N) and small granule chromaffin (SGC-A, SGC-N) cells, and nervous elements present in the gland. The SGC-A and SGC-N showed the same intensity of AChE reaction in A and N cells, respectively. On the whole, the A and SGC-A cells were more reactive than the N and SGC-N cells. The functional role of the SGC cells is discussed on the basis of the cytochemical results.
