- a The intestinal changes are scored according to the average villi/crypt (V/C) ratio plus the grade of epithelial cell desquamation, which is measured as follows: V/C ratio, 0 = normal; (V/C ≥6:1), 1 = mild; (V/C = 5.0 – 5.9:1), 2 = moderate; (V/C = 4.0 – 4.9:1), 3 = marked; (V/C = 3.0 – 3.9:1), 4 = severe; (V/C ≤3.0:1), and desquamation grade, 0 = normal (no desquamation), 1 = mild (a few desquamated cells of tip villous epithelium), 2 = moderate (desquamation of upper villous epithelium), 3 = marked (desquamation of lower villous epithelium), 4 = severe (desquamation of crypt epithelium).
- b Values are mean ± S.D. (n=3). The asterisk indicate significant differences (*p<0.05; *** p<0.001) compared to the positive control.
