Changes of coagulation parameters in tumor bearing mice. Tumor bearing mice were analyzed for coagulation parameters as described in the text in comparison with non-tumor bearing mice. CO: non-tumor bearing control mice; F: mice with F9 teratocarcinoma; C: mice with Colo677 myeloma; L5: mice with L540rec Hodgkin's lymphoma; H: mice with HT29 colon carcinoma; LS: mice with LS174T colon carcinoma; I: mice with IMR5 neuroblastoma. Means and standard deviations (error bars) from groups of 4–18 mice are shown. *: statistically significant versus control mice (p < 0.05).
