[Comparative immunocytochemical study of the neuroglandular hypothalamic CRF system in the postnatal period in dogs and cats].

Immunocytochemical visualization, and comparative morphological analysis of the paraventriculo-infundibular CRF-positive system was performed in new-born dogs and young cats. Our studies underline the identity of this system and its structural similarity among Mammals. They confirm the interspecificity of the antigenic sites recognized by our ovine CRF-antibodies.
