[Pars tuberalis : a neuro-endocrine formation. Study in the piglet].

Pars tuberalis of the young Pig has been studied by cytoimmunological techniques and by electron microscopy. Electron microscopy demonstrates the high content of the area in nervous fibers and aminergy terminals making frequent synapses with granulated glandular cells. Amongst these, the majority were reacting as corticolipotropic cells of the intermediate lobe. However in the new-born pig, these cells, although very active and excreting in the perivascular spaces generally react with the anti-LPH beta immunesera.
