Ferulic acid changes the pattern of Th1/Th2 immune response. At the end of the experiment, serum samples were collected for determining the serum IgG1 and IgG2a level. The quantification of IgG1 and IgG2a was using a commercialized ELISA kit and analyzed in spectrometer. Data were calculated by regression analysis. Each symbol represented an individual sample and the intercept, R 2 of the regression lines, interval of confidence, and P value were further determined in NT (a), Pre-T (b), and Post-T (c) groups.
