title: [Cytotoxic antibodies in the serum of C3H mice after inoculating them with spontaneous mammary gland tumor cells].
abstract: Complement-dependent cytotoxic antibodies against the cells of mammary tumor MMTI appeared in the blood of C3H/He and C3Hf mice at the terminal stage of tumor growth; at the same time the mice of the above-mentioned substrains showed no difference in the degree of reaction. The level of natural cytotoxic antibodies against MMTI tumor cells detected in old C3H/He and C3Hf mice significantly exceeded their level in young mice affected with tumor; however, MMTI tumor cells grew equally fast in both old and young animals. The sera of mice affected with tumor had a weak cytolytic activity against the cells of hepatoma 22a and did not affect L cells and embryonal fibroblasts. The sera were partially exhasted by spleen and renal tissues, as well as the cells of spontaneous mammary tumor obtained from syngeneic animals and were not exhausted by allogenic cells infected with Rauscher murine leukemia virus.
