Dietary Fibre On Cell Proliferation In Large Bowel Mucosal Crypts Near Or Away From Lymphoid Nodules And On Mineral Bioavailability, Ivan Cameron, W. Hardman, D. Heitman, J. Carter
Elaine Hardman Ph.D.
The effect of consumption for 24 weeks of different amounts (0%, 5% or 10% w/w) of fermentable (pectin and guar gum) or nonfermentable (cellulose and lignin) dietary fibres on cell proliferation and other parameters in large bowel mucosal crypts was studied in rats. In all 12 dietary groups, the crypts located over the distal aggregate of lymphoid nodules (ALN) had more colchicine arrested metaphase figures per midaxial crypt section (MC) and a longer crypt column height than crypts located three to four cm away from this ALN. These differences are attributed to the tropic in¯uence of nodular cells in the …
