[Immunofluorencence localization of secretions related to gonadotropic, corticotropic, melanotropic and somatotropic hormones in hypophysis of Nectophrynoides occidentalis].

In Nectophrynoïdes occidentalis, ovine anti-LH anti beta (1-24) corticotropin, both anti alpha and anti beta MSH and bovine anti-STH antisera allowed us to identify by immunofluorescence gonadotropic, corticotropic, melanotropic and somatotropic hypophysial cells of a viviparous toad. The identification of these different cell types was confirmed by applying a classical cytologic technique to the same sections.
