Mutagenicity has been measured in the gastric juice of 228 patients using the Ames bacteriological test system; while mutagenicity in control and duodenal ulcer patients did not differ from saline controls, mutagenicity was significantly increased compared with controls in patients suffering gastric ulcer (p less than 0.002), carcinoma (p less than 0.002), and in patients after gastric resectio...
Polyphenolic compounds present in rosemary were found to have antioxidant properties, anticarcinogenic activity, and to increase the detoxification of pro-carcinogens. The aim of the study was to determine the effect the aqueous extract of rosemary (AER) on mutagenicity induced by methylmethane sulfonate in meristematic cells of Allium cepa, as well as to describe its mode of action. Anti-mutag...
ŠMERÁK P., POLÍVKOVÁ Z., ŠESTÁKOVÁ H., ŠTĚTINA R., BÁRTA I., LANGOVÁ M., TUREK B., BÁRTOVÁ J. (2006): Antimutagenic effect of curcumin and its effect on the immune response in mice. Czech J. Food Sci., 24: 72–83. A wide array of antioxidative and anti-inflammatory substances derived from edible plants have been reported to possess chemopreventive and chemoprotective activities. Among the most e...
The mutagenicity of airborne particulate matter collected in 17 towns of Italy in 1990 was assessed using the Ames test. The mutagenicity of crude extract correlated with amount of lead, suggesting the direct contribution of gasoline car exhausts. Moreover, the mutagenicity correlated with particulate matter amounts. An inverse correlation with temperature was observed. The crude extracts were ...
serious concerns have been expressed about potential health risks of nano silver containing consumer products (agnps) therefore regulatory health risk assessment on such nanoparticles has become mandatory for the safe use of agnpsinbiomedicalproducts with special concerns to the mutagenic potentials. in this study, we examined the inhibitory and mutagenicity effects of agnps in three different ...
Salacia crassifolia (Mart. Ex. Schult.) G. Don. is a bush which belongs to Celastraceae family and occurs specially in Brazilian Cerrado. Its leaves, stem, seeds and fruits are popularly used for several medicinal purposes, such as antitumoral, antirheumatic, anti-inflammatory and antimicrobial. In this study, the mutagenic and antimutagenic activities of S. crassifolia stem bark fractions (hex...
Fecal mutagenicity was measured in 68 patients with colorectal cancer and in 114 controls, using Salmonella tester strains TA98 and TA100 with and without S9 activation. Samples were also tested for fecapentaenes by high-performance liquid chromatography, to permit the separation of fecapentaene and non-fecapentaene mutagenicity. Overall, no significant case-control differences in fecal mutagen...
