The effect of the treatment on the pathology score and the goblet and epithelial cell % in the colonic tissue (least square means with their standard errors).

	Treatment				SEM	Contrasts
	Control	Basal DSS	Laminarin DSS	Chitosan DSS		1	2	3
Pathology score	1.0	2.0	1.7	1.9	0.330	*	NS	NS
Goblet cell %	14.9	27.02	23.12	22.54	2.72	**	NS	NS
Epithelial cell %	85.1	72.99	76.88	77.46	2.72	**	NS	NS

The pathology scores range from 1–5 as follows: 1 = normal, non-ulcerating epithelium with a reduced lamina proprial cell infiltration; 2 = normal with a lamina proprial cell infiltration within the normal spectrum; 3 = colonic samples with focal (single) regions of ulceration; 4 = samples with multiple foci of ulceration interspersed between regions of normal colon and 5 = samples with diffuse ulceration. Contrasts: (1) Control vs. Basal DSS; (2) Basal DSS vs. Laminarin DSS; (3) Basal DSS vs. Chitosan DSS; NS, non-significant; * p < 0.05; ** p < 0.01.
