title: Behaviour of lysosomal enzymes in the small intestine after multiple daily fractionation.
abstract: Modifications in the activities of some lysosomal enzymes were studied in the small intestine after irradiation on the abdomen by multiple daily fractionation of 3 Gy per fraction every 12 hours. Total doses of 6 and 12 Gy were studied. With lower dose variations were slight. The modifications of acid phosphatase an cathepsin D appeared very low, whereas beta-glucuronidase increased until 72 hours after the last fraction and then returned to control values. With respect to 8 Gy single dose the injury appeared comparatively similar.
