A baby born with esophageal atresia and a laryngeal cleft is presented. Retained salivary secretions and aspiration were a constant management problem whilst the baby was waiting for delayed primary repair of the atresia. The use of anticholinergic agents resulted in thickening of secretions which were difficult to suction and ultimately led to increasing respiratory compromise.

Bovine pituitary intraglandular colloid thought to be a waste product, is the holocrine secretion of intermediate lobe cells. It is housed in the intraglandular lumen (residual lumen) and is extruded into the venous circulation of the cavernous sinuses via clefts in the capsule of the gland aligned with the intraglandular lumen. Intraglandular colloid, fraction F5 (mol.

Immunodiffusion of fractions of intraglandular colloid shows determinants sharing antigenic specificity with GH, FSH, CSF and serum immunoglobulins. The fractions tested by PAGE show determinants common to intraglandular colloid, CSF and serum albumin.

The production of intraglandular colloid, brought about by the cyclic breakdown of intermediate lobe cells, is related to the synthesis of hormones in the hypophysis. By analyzing the 'shift' of the amino acid, cystine, during various phases of the gland's cycle it is apparent that hormones, as well as other protein determinants of immunological importance, are transported by way of the intraglandular cleft to the venous circulation and to the cerebrospinal fluid.
