Mutagenicity and co-mutagenicity of catechol on salmonella
Mutation Research Letters, 1983Catechol was not mutagenic for Salmonella typhimurium TA98, TA100 or TA1537 in the presence or absence of S9 mix. At the lower level of S9 in the Ames method, the mutagenic activity of benzo[a]pyrene decreased with the increased addition of catechol.

On the mutagenicity of nitrofurans
Mutation Research, 1974Summary 22 nitrofurans were tested for ability to induce revertants of E. coli WP2 and its uvrA - derivative from tryp - to tryp +. All proved to be mutagnic while two furan analogues (lacking the nitro- group) proved to be inactive. Test strains containing exrA - or recA - genes were not induced to mutate, suggesting that mutants arise in the

Mutagenicity of sulphonylureas
Mutation Research/Genetic Toxicology, 1980The 11 derivatives of beta-cytotropic sulphonylureas commonly used in the treatment of diabetes mellitus were tested in vivo in the highly sensitive sister-chromatid exchange test. Chlorpropamide and tolbutamide gave a positive reaction with a clear dose-response in Chinese hamsters and mice.

Mutagenicity of radiations and chemical mutagens in Sorghum
Theoretical and Applied Genetics, 1970A comparative study on the relative mutagenicity of radiations (X-and gamma rays) and chemical mutagens (EMS, MMS, dES and NEU) in inducing chlorophyll, viable and total mutations was made on three cultivated varieties (Co. 11, Co. 12 and Co. 18) of Eu-Sorghum. A critical comparison of the chlorophyll, viable and total mutations shows that the mutation

Mutagenicity of proanthocyanidins
Food and Chemical Toxicology, 1987Several procyanidins with different degrees of polymerization (dimers, a trimer and a polymer) and extracted from different natural sources were found to be non-mutagenic in the Salmonella mutagenesis assay system. A mutagenic impurity in procyanidin B-4 was isolated by means of reversed-phase high-performance liquid chromatography (HPLC) and ...

Mutation Research/Genetic Toxicology, 1978
The commercially available volatile anesthetic fluroxene (2,2,2-trifluoroethyl vinyl ether) which contains the stabilizer N-phenyl-1-napthylamine, was tested for mutagenicity using four strains of S. typhimurium, TA1535, TA1537, TA98 and TA100, and one strain of E. coli, WP2. In addition, purified fluroxene; N-phenyl-1-napthylamine; trifluoroethanol, a
