The levels of galactosyltransferase activity in sera from normal children and patients with cystic fibrosis.

The levels of galactosyltransferase have been studied in the sera obtained from 
59 normal individuals varying in age from 5 - 19 years, 
and from 29 cystic fibrosis patients varying in age from 5 
- 33 years. The enzyme level found in children was lower 
than that in adults. The levels in the sera of cystic 
fibrosis patients was found to be about half of that in 
the normal sera for the corresponding age group. In those cystic 
fibrosis patients over 20 years of age, normal levels were found.
