    We investigated the effects of teichoic acid (TA) from Staphylococcus aureus Wood 46 on tumor growth and metastasis of the experimental Lewis lung carcinoma (LLC) in mice. Intranasal administration of TA alone aggravated both tumor growth and metastasis, whereas combined administration of TA with a synthetic bimetallic (copper: cadmium) ethylene diamine complex PO244 resulted in pronounced antitumor and antimetastatic effects. The group of animals subjected to the combined treatment with TA and PO244 manifested the highest degree of lymphocyte infiltration into the tumor tissue, compared to the control group and those exposed to TA or PO244 alone. Moreover, the combined treatment negatively affected the adhesive properties of peritoneal macrophages in the LLC bearing mice. Co-cultivation of the isolated macrophages with primary LLC cultures revealed significant (p < 0.05) cytotoxic and cytostatic effects, detected as an increased level of apoptosis and a reduced fraction of replicating cells.ИсслСдовали ΠΌΠΎΠ΄ΠΈΡ„ΠΈΡ†ΠΈΡ€ΡƒΡŽΡ‰Π΅Π΅ влияниС Ρ‚Π΅ΠΉΡ…ΠΎΠ΅Π²ΠΎΠΉ кислоты (ВК) Π½Π° рост ΠΈ мСтастазированиС ΠΏΠ΅Ρ€Π΅Π²ΠΈΠ²Π°Π΅ΠΌΠΎΠΉ ΠΊΠ°Ρ€Ρ†ΠΈΠ½ΠΎΠΌΡ‹ Π»Π΅Π³ΠΊΠΈΡ… Π›ΡŒΡŽΠΈΡ Ρƒ ΠΌΡ‹ΡˆΠ΅ΠΉ.
