Figure 4. — Variations of interferon (IFN)-γ (circle symbols) and interleukin (IL)-4 (triangle symbols) expression levels in blood cells. To qualitatively evaluate acupuncture, cytokine expression levels in the cells were counted with fluorescence-activated cell sorter. The levels of IFN-γ and IL-4 containing cells were counted as an indicator of cellular (Th1) and humoral (Th2) immunity, respectively. The solid circles represent mean values.
