The immune response of BALB/c mice is promoted by λ-COS. (a) The effect of λ-COS on the indexes of spleen and thymus in mice. The indexes were calculated by comparing their weights with the total weights of mice. (b) The phagocytic ability of peritoneal macrophages after administration with λ-COS in BALB/c mice. The cells were incubated with neutral red to indicate their phagocytic ability (n = 6). * p < 0.05 and ** p < 0.01 versus the normal group. ^# p < 0.05 and ^## p < 0.01 versus the 5-FU group.
