Abstract
Bioptic specimens taken from the lower duodenum were studied in 12 volunteers at different times of the day for the activity of 4 marker enzymes. The activity of alkaline phosphatase in brush border of villi was the strongest at 06h, while the nadir at 22h; acid phosphatase activity in the supranuclear zone and in macrophages was the strongest at 06h and reduced at other test times; the peak activity of 5' nucleotidase was found at 14h with the nadir at 02h; activity of NADPH was the strongest at 18h. It is suggested that circadian rhythmicity of intestinal function exists in man like in animals.
