Postprandial Response and Diurnal Variation of Serum Cationic Trypsin-Like Immunoreactivity in Man

Abstract

In eight healthy volunteers a standard test meal caused an early, transient, but significant increase in serum cationic trypsin-like immunoreactivity (CTLI). Serum CTLI was studied for 24 h in another six healthy volunteers who had four regular meals and performed their usual activities. It showed a diurnal variation with significantly higher values in the late evening and early night than the initial morning value.

Key words:

• Cationic trypsin
• diurnal variation
• meals
• radioimmunoassay
