This paper continues the study of the relationship between electron density and carcinogenic activity for compounds related to p-dimethylaminoazobenzene (Cancer Res., 29: 1341-1344, 1969) and reports on the seven p-dimethylaminophenylazoquinolines. A relationship was found between carcinogenic activity and the pKfl of the amino nitrogen in these compounds, and in this new series a relationship ...

the anti-carcinogenic activity of certain organic compounds, some of which are closely related to the carcinogenic hydrocarbons. Lacassagne et al. (2, 3) have reported that the addition of certain weak carcinogens to stronger ones will inhibit the carcinogenic activity of the latter when applied to the skin of mice. They studied the effects of 1,2,,5,6-dibenzofluorene and of chrysene when appli...

Purpose. Determining the level of soil pollution with heavy metals in “2 July” neighborhood, as well researching impact on health neighborhood’s residents. The scope research was to know which age is most at risk from based Theory Risk Assessment, Non-carcinogenic assessment, and Carcinogenic assessment. Methodology. samples neighborhood were taken spontaneously. After preparation samples, lead...
