Effects of baicalin on the MAPK signalling pathway activated by G. parasuis. Before G. parasuis challenge, the piglets in the EP group were injected intraperitoneally with EP, and the piglets in the FM group were injected intramuscularly with FM. Aortic vessels were collected, and the protein expression levels of ERK (A), p-ERK (B), JNK (C), p-JNK (D), P38 (E) and p-P38 (F) were determined. G. parasuis: HPS. 25–100: the piglets were injected intramuscularly with baicalin at 25, 50, or 100 mg/kg BW. ^##p < 0.01 vs control. *p < 0.05 vs the infection group, and **p < 0.01 vs the infection group.
