Fig 1. Intestinal disaccharidase activities, i.e., lactase, maltase and sucrase (U/mg protein), in the proximal small intestine (A), and the portion of adult-type enterocytes, lacking supra-nuclear vacuoles, appearing on the villi in the distal small intestine (B) after gavage feeding the pancreatic enzyme preparation, Creon, or α-lactalbumin (control) during 14–16 days of age in 17 d-old suckling rats.

Statistically significant differences between control and enzyme-treated groups (mean ± SD, n = 10–11) are indicated by *** P < 0.001.
