A–E, Percentage of the indicated lymphocytes in PBL of melanoma-bearing mice at the indicated days after subcutaneous tumor inoculation. F–J, Number of specific types of lymphocytes in 700 μl of blood of the water-drinking and alcohol-consuming mice at the indicated days after subcutaneous tumor inoculation. Water: Water-drinking, melanoma-bearing mice. ETOH: Alcohol-consuming, melanoma-bearing mice. Each group contained 7–10 mice. Experiments were repeated once with the similar results. Water-drinking group different from alcohol-consuming (ETOH) group on the indicated day, * p<0.05; ** p<0.01; *** p<0.001.
