The relative amount of mRNA was calculated using the comparative Ct method, and mRNA expression of sham-operated mice was used as a calibrator. Data are presented as the mean ± SEM. ^∗Significantly different from the sham group (p < 0.05). ^†Significantly different from the saline group (p < 0.05).

A100, A200, and A400, respectively, indicate treatment with 100, 200, and 400 mg Astragalus polysaccharides/kg of body weight.

IFN: interferon; IL: interleukin; TGF: transforming growth factor.
