Effects of four regulating-intestine prescriptions on pathology and ultrastructure of colon tissue in rats with ulcerative colitis

Table 1 Criteria for scoring the gross morphologic damage of colon tissue[6-9]

Score	Gross morphology
0	No damage
1	Localized hyperemia with no ulcers
2	Linear ulcers with no significant inflammation
3	Linear ulcers with inflammation at one site
4	More site of ulcers and inflammation, the size of ulcers <1 cm
5	Multiple inflammation and ulcers, the size of ulcers≥1 cm

Table 2 Effect on weights in rats of FRIP (mean±SD)

Group	Case (n)	Weights (g)
Normal control group	12	352.5±20.7b
Model group	10	307.8±15.3d
SASP group	9	321.5±18.7ad
WMW group	11	340.3±16.8bc
BTWT group	10	331.4±13.8bd
SLBSS group	9	325.6±18.4ad
TXYF group	10	328.7±10.5ad

^aP<0.05,

^bP<0.01 vs model group;

^cP<0.05,

^dP<0.01 vs normal control group.
