Figure 3 .

Effect of diet on brush border hydrolase activities of distal colonic mucosa. The diets contained no fibre, wheat bran, or methylcellulose. Alkaline phosphatase and dipeptidylpeptidase IV (DPPIV) activities differed significantly across the dietary groups (p<0.001 and p<0.05 respectively, ANOVA). Alkaline phosphatase activity in the methylcellulose group and DPPIV activity in the wheat bran group were significantly different to those in the other groups on multiple comparisons (p<0.05).
