Modification effect of sodium salts and ethers of linolenic, arachidonic and alpha-linolenic acids on the growth of transplantable mouse tumors was examined. Polyunsaturated fatty acids (PUFA) enhanced the growth of mammary adenocarcinoma Ca-755, whereas the opposite effect was observed in mice with leukemia L-1210 and sarcoma 180. No differences in the growth of melanoma B-16 and Lewis lung carcinoma were noted in control and experimental animals. Modification effect of PUFA was significantly suppressed by prostaglandin inhibitor indomethacin and to a lesser extent by antioxidant alpha-tocopherol.
