Determination of the effect of baicalin, levamisole, and BMS-1 on cytokine production in the blood of piglets challenged with G. parasuis. Blood was collected, and total RNA was isolated. The cytokine expression levels were determined by RT-PCR. A IL-1β; B IL-2; C IL-8; D IL-10; E IL-18; F TNF-α; G IFN-γ; BA: baicalin; ###P < 0.001 versus controls; **significance at P < 0.01; ***significance at P < 0.001.
