the development of neuropeptide and neurotransmitter-related immunoreactivities in the rat olfactory bulb were investigated immunohistochemically by using antisera raised against substance p ( sp ) , cholecystokinin-8 ( cck ) , neurotensin ( nt ) , leucine-enkephalin or methionine-enkephalin-arg6-gly7-leu8 ( enk ) , somatostatin ( som ) , neuropeptide y ( npy ) and tyrosine hydroxylase ( th ) .
