Abstract：
:The presence of corticotropin-releasing factor-like material in the intermaxillary glands was studied by immunocytochemical techniques during the metamorphosis of Bufo arenarum. The intermaxillary glands appeared at stage XV (midprometamorphosis) with CRF-like material slightly immunoreactive. These glands are located posterior to the premaxillae and between the nasal capsules in the roof of the mouth and are formed of alveoli or tubules. During metamorphic climax, corticotropin-releasing factor-like material was identified strongly immunostained at the apices of the secretory cells. It was observed that collecting ducts of the gland open to the anterior palatal surface suggesting that the secretion could be ingested by tadpoles. Our results clearly showed that ir-CRF-like material present in the intermaxillary glands is ingested by tadpoles during metamorphosis and could play an important role during amphibian development.
