| Abstract: | The study of the effect of ascitic fluid and dialysate of Ehrlich ascites tumor cells (M.m. less than 15 kDa) on the growth of Ehrlich carcinoma and teratoma T-36 has shown that both the ascitic fluid and dialysate can protect tumor cells in vivo. The number of animals with tumors increased from 0% in control animals to 60 and 20%, respectively, in experimental ones after transplantation i.m. of 20 x 10(3) Ehrlich tumor cells into mice. Compared to control, ascitic fluid and dialysate of Ehrlich ascites tumor cells increased the rate of tumor growth to 195 and 153%, respectively. It is suggested that this test-system simulates the effect of tumor humoral factors in vivo. |
