Corticosterone, ACTH, and noradrenaline levels in plasma of non-tumor- and B16-F10-bearing (lung metastases) mice. Corticosterone, ACTH, and noradrenaline levels were measured as indicated under Materials and methods. Blood was collected from the tail vein during the 24-h period. Data are mean values + S.D. (error bars) of 7–8 different animals. *P< 0.05 comparing B16-F10 (7 days after tumor inoculation)-bearing mice versus non-tumor-bearing mice; +P< 0.05 comparing 15 h versus 6 h.
