Figure 3: Effects of high-molecular weight fraction of Cynanchum auriculatum on natural killer cell activity and splenic lymphocyte proliferation in cyclophosphamide-induced immunosuppressed mice. (a) Natural killer cell activity was determined by lactate dehydrogenase assay. The E: T ratio indicated ratio of effector cells (splenocytes) and target cells (YAC-1 cells); (b) Concanavalin A- and lipopolysaccharide-induced T- and B-lymphocytes proliferation. Cell proliferation was measured by using CCK-8 kit. Values with different letters are significantly different (P < 0.05)
