Evaluation based on macroscopic features in acetic acid-induced colitis

Group	Mean of macroscopic scores ± SEM
Control	4.46 ± 0.57
Prednisolone	1.12 ± 0.14*
Z 400	4.23 ± 0.62
Z 600	2.34 ± 0.49*
Z 900	1.11 ± 0.15*,†

Observations were recorded by histopathologist and scored as described in Methods section. Each value represents mean of macroscopic scores ± SEM of six animals in each group.

*Significant (P < 0.01) decrease in macroscopic score values compared to control.

^†The difference in macroscopic score values of Z. multiflora (Z)-treated and prednisolone-treated groups in not significant.
