title: [Immunocytologic detection of material related to various vertebrate peptides in the nerve ring of the snail (Helix aspersa Müller)].
abstract: The immunocytological method applied to the brain of the snail (Helix aspersa Müller) reveals positive antigenic sites with several antibodies raised against vertebrate peptides: somatostatin, ACTH-17-39, beta-MSH, beta-endorphin, methionine-enkephalin. The distribution of the positive structures (perikarya, fibers) in the ganglia, in the commissure or in the cerebral vessels is given and the presence of these substances is discussed.
