[The effect of ascitic fluid on the growth of Ehrlich tumor and Lewis carcinoma]

Abstract

In 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 and Lewis carcinoma it was found that the ascitic fluid significantly decreased the size of Ehrlich tumor (by more than 50% on day 9-25 after the tumor cell inoculation). It also reduced Lewis carcinoma tumor volume by more than 30% during 3 weeks after the tumor cells inoculation. Dialysate of Ehrlich tumor cells significantly inhibited the growth of Ehrlich tumor too. It is suggested that this test-system simulates inhibition of a small tumor by a big tumor in vivo.
