[Study of cytochemical properties in the nucleus paragigantocellularis lateralis of rats].
The distribution of cell bodies containing serotonin (5-HT)-, substance-P (SP)-, L-enkephalin (L-ENK)- and neuropeptide Y (NPY)-like immunoreactivity (IR) in the nucleus paragigantocellularis lateralis (PGCL) of the rat was studied immunocytochemically. Perikarya containing 5-HT-, SP- or L-ENK-IR were found throughout the rostro-caudal extent of the PGCL. Large, well-staining 5-HT cells densely clustered rather near the ventrolateral surface of the medulla. SP- and L-ENK-IR were distributed more extensively and located more lateraly. A few of perikary on containing NPY-IR were found primarily in the area from the medium to caudal region. The results provided morphological basis for further study of the neurochemical properties of PGCL neurons involved in the regulation of cardiovascular, respiratory and other functions in the rat.
