title: Influence of increased temperature on the inhibition of rat osteosarcoma cell multiplication "in vitro" by interferon.
abstract: Purified rat interferon preparations proved effective in inhibiting cell multiplication in a rat osteosarcoma cell line. A pronounced increase in the inhibitory activity was found with increasing temperature. At 39 degrees C 20 Interferon units/ml appeared to be cytotoxic whereas incubation of cells with 2,000 Interferon units/ml at 35 degrees C resulted in a cytostatic effect.
