The behaviour of intestinal lactase has been studied in rats after irradiation. The significant increase of activity is not immediate, but slowly and progressively starting from 4 hrs after irradiation. The modifications of the activity are slow and gradual also during the reduction phase. This disaccharase does not show a return to normal values even after three weeks. We suggest that hypothesis that the increase could be due to a modification of the normal synthesis of enzymes caused by irradiation.
