The distribution of tachykinin-like immunoreactivity (LI) was studied in the adrenal gland of the frog Rana ridibunda using the immunofluorescence technique. A dense network of varicose fibers immunoreactive to both substance-P (SP) and neurokinin-A (NKA) was found in the adrenal tissue. In contrast, no positive fibers could be detected using(More)
The adrenal gland of amphibians is composed of a mixed population of adrenochromaffin and corticosteroid-secreting cells. It has previously been shown that chromaffin cells synthesize several bioactive substances (including biogenic amines and neurotransmitters) which may act locally to regulate corticosteroid secretion. In the present report, we have(More)
