CD45-positive cells were gated to determine the population of lymphocytes by flow cytometry. Populations of T and B cells were determined as the percentages of CD3ε+CD19− and CD3ε−CD19+ cells among CD45-positive cells. Percentages of T helper (Th) and cytotoxic T (Tc) cells were, respectively, determined by CD4+CD8− and CD4−CD8+ cells in CD3ε-expressing T lymphocytes. Values are presented as the mean ± SEM. Significantly different from the sham group (). A100, A200, and A400, respectively, indicate treatment with 100, 200, and 400 mg Astragalus polysaccharides/kg of body weight.
