[The effect of antithymocyte serum on the natural cytotoxicity of C3HA mouse splenocytes in the early periods after 20-methylcholanthrene administration].

The role of T-lymphocytes in natural cytotoxicity of splenocytes of C3HA mice after a single injection of 20-methylcholanthrene (20-MC) was investigated. A splenocyte suspension was treated with anti-T-cell serum and complement. This treatment was not shown to exert influence on the natural cytotoxicity of splenocytes within 1-13 days after injecting 20-MC.
