| Abstract: | The intravascular (iv) or intramuscular (im) inoculations of a suspension of Lewis carcinoma cells induced metastatic tumor nodules in the lungs of C57Bl/6 mice. The administration of curantil (dipyridamole) (500 mg per 20 g-mouse, per os) once a week beginning one day after iv tumor cells inoculation (2 X 10(5) cells) reduced 4-fold the number of tumor nodules. The administration of curantil one day after im tumor cells inoculation (2 X 10(6) cells) reduced 2-fold the number of tumor nodules. The combined treatment of curantil (4-, 10-days after inoculation) and well-known inducer of interferon poly I:poly C (50 mg per 20 g-mouse, 1-, 7-, 14-days after inoculation tumor cells) had no synergistic effect. |
