Cytology and cytochemistry of the hypophysis of the freshwater teleost Rhamdia hilarii (Val., 1840).

The characterization of cell types in the rostral pars distalis, proximal pars distalis and pars intermedia of the Bagre fish hypophysis during the reproductive cycles, as well as a cytochemical study of mucosubstances were undertaken. The cytophysiological relationship among the different acidophilic, basophilic and chromophobic cells with the several hypophyseal hormones was also considered.
