Changes in peripheral blood Th1/Th2 cell ratios. Flow cytometry was used to detect (a) the percentage of Th1 cells in peripheral blood by labeling with anti-CD4 and IFN-γ (CD4+IFN-γ+) fluorescent antibodies, (b) the percentage of Th2 cells using anti-CD4 and IL-4 (CD4+IL-4+) fluorescent antibodies for subjects in the SCIT group at three time points; (c) changes in the Th1/Th2 ratio for the SCIT and no-SCIT groups at the three time points. Designates intergroup difference; designates a intergroup difference.
