Germ cell mutagens: Risk assessment challenges in the 21st century
Environmental and Molecular Mutagenesis, 2010Heritable mutations may result in a wide variety of detrimental outcomes, from embryonic lethality to genetic disease in the offspring. Despite this, today's commonly used test batteries do not include assays for germ cell mutation.

Modulation of mutagenicity of various mutagens by lignin derivatives
Mutation Research/Genetic Toxicology and Environmental Mutagenesis, 2003The effect of lignin on cytotoxicity, mutagenicity and SOS response induced by 4-nitroquinoline-N-oxide (4NQO), 3-(5-nitro-2-furyl)acrylic acid (5NFAA), 2-nitrofluorene (2NF) as well as hydrogen peroxide was investigated in bacterial assay systems, i.e. the Ames test with Salmonella typhimurium TA98, TA100, TA102 and the SOS chromotest with Escherichia

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 ...

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.

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

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.

Infidelity of DNA synthesis in vitro: screening for potential metal mutagens or carcinogens.
Science, 1976Thirty-one metal salts have been tested for their ability to affect the accuracy of DNA synthesis in vitro. All ten salts of metal carcinogens decreased the fidelity of DNA synthesis.

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 ...
