Fig. 3. (A) Changes in the proportion of beads found in each section after feeding (immediately following 0 h) when compared to total bead count along GI tract (%). Values are means ± s.e.m. (N=7, except at 96 h in the mid intestine, N=3). (B) Changes in the proportion of [³H]-PEG 4000 counts found in each section after feeding when compared to total counts along GI tract (%). Values are means ± s.e.m. (N=7, except 96 h in the mid intestine, N=3). *Significant difference from the proportion of beads in the corresponding section in A.
