title: Cell multiplication of an ascites tumour in the presence of superoxide dismutase and catalase.
abstract: Superoxide dismutase and catalase were demonstrated to favour the multiplication of ascites tumour cells in vitro. It is proposed that these enzymes neutralize the O2-. and H2O2 that may accumulate in the neoplastic cell and that cell damage occurs because the cellular levels of both enzymes are low.
