Antimutagenic effects in humans

Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 1992
The application of antimutagenicity studies to human somatic mutation is discussed, with emphasis on the potential for future studies. Five assay-gene combinations are now available for measuring human somatic mutation in lymphocytes and erythrocytes. Results with these combinations have defined the human background levels, and show clear responses of ...

Antimutagenic Effects of Chlorophyllin

1990
It has been suggested that the majority of human cancers are caused by environmental exposures, but little is known about the effective environmental and occupational risks of cancer. It is likely that the process of mutagenesis and the intricate balance between mutagenesis and antimutagenesis are involved in aging, evolution, and other fundamental ...

Antimutagenicity of components of dairy products

Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 1995
This paper reports the potential antimutagenicity of some components of dairy products. For both milk and fermented milk, Bifidobacterium sp. Bio (strain Danone 173010), casein and calcium showed a dose-dependent antimutagenic activity against benzo[a]pyrene mutagenicity in the Ames test using Salmonella typhimurium TA98.

Antioxidants/antimutagens in food

Critical Reviews in Food Science and Nutrition, 1990
Oxygen is indispensable for aerobic organisms including, of course, human beings, but it is believed that oxygen also may be responsible for undesired phenomena. In particular, oxygen species such as hydrogen peroxide, superoxide radical anion, and singlet oxygen are proposed as agents attacking polyunsaturated fatty acids in cell membranes, giving ...

Antimutagenicity of propionic acid bacteria

Mutation Research - Fundamental and Molecular Mechanisms of Mutagenesis, 1991
The antimutagenicity of the cell extracts of Propionibacterium shermanii VKM-103, P. pentosaceum CCM 1859 and P. acnes CCM 3322 against mutagenicity of sodium azide and N-methyl-N'-nitro-N-nitrosoguanidine was demonstrated for the first time. The extracts of propionic acid cocci didn't show such effect.

Antimutagens and anticarcinogens in foods

Food and Chemical Toxicology, 1994
The role of dietary factors in the prevention of major chronic diseases, cancer in particular, is under intensive investigation by many laboratories around the world. Evidence from epidemiological studies and tests in laboratory animals suggests that food consumed by the general population contains certain ingredients that may have a role in reduction ...

Vitamins as antimutagens: Advantages and some possible mechanisms of antimutagenic action

Mutation Research/Reviews in Mutation Research, 1997
Dietary natural inhibitors of mutagenesis and carcinogenesis are of particular importance because they may be useful for human cancer prevention and do not have undesirable xenobiotic effects on living organisms. As was shown in numerous experiments, many endogenous substances, usually obtained in food or synthesized by cells, possess some inhibitory ...

Antimutagenic Properties of Green Tea

Plant Foods for Human Nutrition, 2005
In this work biological effects of two common kinds of green tea (Chinese Gunpowder and Japanese Sencha) were analyzed using three independent tests of antimutagenicity: 1) the Ames test with Salmonella typhimurium TA98, 2) cytogenetic analysis of peripheral blood lymphocytes (CAPL), and 3) test with Saccharomyces cerevisiae D7.

Antimutagenic properties of ubiquinone-10

Bulletin of Experimental Biology and Medicine, 1994
The effect of biotechnologically obtained ubiquinone-10 on the level of photrin- and dioxydin-induced chromosomal aberrations is studied for different doses of the preparations by assessing chromosomal aberrations in bone marrow cells of C57B1/6 mice. It is shown that ubiquinone-10 does not exhibit its own mutagenic effect and does not potentiate the ...
