title: Comparative data on acetylcholinesterase cytochemistry in various chromaffin cell types of Discoglossus pictus (Amphibia, Anura).
abstract: 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.
