title: [The testing of the carcinogenicity of dispirotripiperazine derivatives by combined administration with sodium nitrite].
abstract: The cancerogenic activity of the dispirotripiperasinium derivatives prospidine and spirobromine was tested in concurrent use with sodium nitrite. The drugs were intragastrically administered once a week. It was combined with sodium nitrite, 35 mg/kg, to non-inbred rats of both sex during 24 months. A morphological study revealed no statistically significant reduction of latency and no increase in the incidence of tumors in laboratory animals. No cancerogenic effect of sodium nitrite was found.
