Figure 2. HKL suppressed inflammatory factors expression at mRNA level. UC rats were treated with water, 5-ASA and HKL for 3 days, 7 days and 10 days. Tissues were harvested for qRT-PCR analysis (n = 3 at each time points in each group). Each sample was tested in triplicate. *, P < 0.05; **, P < 0.01 compared with control group. # P < 0.05, ## P < 0.01 compared with water group.
