The adrenal cortex in cystic fibrosis of the pancreas.

The morphologies of the adrenal cortical zones of 25 children with cystic 
fibrosis and 24 control patients are presented. A technic for objective 
measurement of these zones is described. Hyperplasia of the zona glomerulosa 
in the children with cystic fibrosis is significant and may be 
related to chronic loss of salt in the sweat or demands 
placed on renal salt-conserving mechanisms.
