摘要

The relationships between lifestyles and urinary mutagenicity were investigated by using blue rayon extraction from 33 healthy male workers' urine. Subjects were classified into three groups, as "good", "moderate", and "poor" according to their responses on a questionnaire regarding eight health practices (cigarette smoking, alcohol consumption, eating breakfast, hours of sleep, hours of work, physical exercise, caring about nutritional balance, mental stress). The better lifestyle groups exhibited the lower mutagenicity. Subjects in a "good" group showed significantly lower urinary mutagenicity than those both in a "moderate" (p < 0.05) and a "poor" (p < 0.05) groups at fraction number 1 to 3 that were given after ingesting fried beef. These tendencies also found at fraction number 8 to 9 that were given after smoking, although not significant. The lifestyles were significantly associated with the urinary mutagenicity, and the results suggested that not only particular lifestyle factor but also some combinations with smoking significantly enhanced with the urinary mutagenicity.
