Influence of digitoxin treatment on number and size of lung metastases from tumor cells implanted intravenously. (A) Number of lung metastases following intravenous administration of tumor cells. Color code: red = digitoxin; blue vehicle control. Medians are identical P, 2 tailed = 0.492; N, digitoxin = 13; N, control = 14. (B) Area occupied by lung metastases following intravenous administration of tumor cells. Color code the same as in part A. Significantly less area occupied by tumor cells in digitoxin-treated rats (P, 2 tailed = 0.004; N, digitoxin = 11; N, control = 12). (C) Bar plot for data in Part A. (D) Bar plot for data in Part B.
