Anti-mutagenicity of catechin against environmental mutagens
Mutagenesis, 1988Catechu is the non-mutagenic component of betel quid. We have tested catechu extract and catechin for anti-mutagenic activity in Salmonella typhimurium strain TA98 against environmental mutagens relevant to India. Catechu extract, as well as catechin, shows a dose-dependent decrease in the mutagenicity of tobacco and masheri extracts, and bidi and ...

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

Mutagen and anti-mutagen in ginger, Zingiber officinale
Mutation Research Letters, 1982When rhizome juice of ginger, zingiber officinale, was added to a solution of 2(2-furyl)-3(5-nitro-2-fury)acryl amide (AF2) or N-methyl-N'-nitro-N-nitrosoguanidine (NTG), mutagenesis by these chemicals was markedly increased. As a result of the component fractionation of the ginger juice, it was found that [6]-gingerol was a potent mutagen.

A methanol extract from clove (Syzygium aromaticum) showed a suppressive effect of the SOS-inducing activity on the mutagen 2-(2-furyl)-3-(5-nitro-2-furyl)acrylamide (furylfuramide) in the Salmonella typhimurium TA1535/pSK1002 umu test.

Mutation Research/Reviews in Genetic Toxicology, 1975
Seventeen different reports are available dealing with the mutagenic effects of saccharin. Many of these are short abstracts, carrying incomplete information. Mainly tested as its sodium salt, saccharin has been found to be weakly mutagenic in Salmonella at very high doses, in Drosophila at moderate doses, and in mice at moderate to high doses.

A number of metals are mutagenic in bacteria or phage. These include compounds of arsenic, chromium, copper, iron, manganese, molybdenum, platinum, and selenium. Compounds containing alumium, antimony, arsenic, cadmium, copper, lead, mercury, nickel, and tellium have been shown to induce chromosomal aberrations or abnormal cell divisions in animal or ...

Science of The Total Environment, 1988
Recent studies suggest that fluoride may be genotoxic. While the concentration of fluoride in artificially fluoridated water (1 mg Fl-1) is generally considered to be "safe", levels of fluoride present in a number of widely used dental health products, such as fluoride-containing toothpaste, appear to be potentially mutagenic.
