Using a technique by which binding sites for two antibodies can be visualized in single tissue sections, we have studied the distribution of neurones containing DOPA decarboxylase-like and dopamine beta-hydroxylase-like immunoreactivity in ganglia of dog sympathetic chain. Three types of neurones could be distinguished: those that contained both enzymes,(More)
To determine whether dihydroxyphenylalanine (DOPA) decarboxylase (DDC) activity in the terminal regions of noradrenergic axons varies with axonal length, we compared the pattern of immunohistochemical staining for DDC in the 'short' terminal nerves of dog vas deferens with that in the 'long' nerves of spleen and atrium. The terminal nerves supplying the(More)
We have compared the pattern of neural catecholamine fluorescence with that of immunoreactivity for the catecholamine-synthesizing enzymes tyrosine hydroxylase (TH) and DOPA decarboxylase (DDC) in dog atrium, which is innervated by noradrenergic nerves, and in dog kidney, which is thought to be supplied by dopaminergic nerves as well. In both tissues the(More)
