Optimal dosing time of Dachengqi decoction for protection of extrapancreatic organs in rats with experimental acute pancreatitis

Figure 2 Serum amylase levels in rats. Rats in each treatment group were orally administered with Dachengqi decoction (DCQD), and rats in each control group and SOG₂ were orally administered with normal saline. SOG₂: Sham-operated group with the dosing time at 4 h after operation; 4-4, 12-4, and 24-4: Rats were dosed with DCQD at 4 h, 12 h, and 24 h, respectively, after AP induction and were euthanized at 4 h after dosing; 4-24, 12-24, and 24-24: Rats were dosed with DCQD at 4 h, 12 h, and 24 h, respectively, after AP induction and were euthanized at 24 h after dosing. Heart blood samples were collected to detect the amylase levels. Data are expressed as the mean ± SD (n = 6). ^eP < 0.05 vs SOG₂, ^fP < 0.05 vs control group.
