Abstract
The morphological relationship between nitric oxide (NO) and catechola mines in the solitary nucleus (SOL) and ventrolateral medulla oblongat a (VLM) was studied by a double immunostaining method with antibodies against NO synthase (NOS), an NO-synthesizing enzyme, and tyrosine hyd roxylase (TH), a catecholamine-synthesizing enzyme. Although NOS- and TH-immunoreactive neurons were widely distributed in the SOL and VLM, these immunoreactivities did not coexist in any single neurons. NOS-im munoreactive neurons formed clusters in some restricted regions, i.e. in the medial subnucleus of the SOL, where both NOS- and TH-immunoreac tive neurons showed a complementary distribution. These findings sugge st that NO-producing neurons constitute a subclass that is distinct fr om that of catecholaminergic neurons.
