Analyzing the disease activity index (DAI) change after 4 and 7 days of treatment with 4% DSS. 4% DSS insulted animals showed no statistically significant difference in DAI between all groups at day 4. After seven days of 4% DSS treatment, the Pg-treatment alone group (group 2) showed in the DAI score a slight increase but no significant difference with the control (no treatment, group 1) group. The 4% DSS treatment group (group 3) had two points, and 4% DSS plus Pg group (group 4) had three points in the DAI score. Data were presented as the means ± SD (n = 3). ###
p < 0.001, compared with the control group; *** p < 0.001, compared with the 4% DSS group.
