Carcinogenic substances in human tissues.
Some of the problems presented by the carcinogenic substances that have been extracted from human tissues will be solved only when these compounds have been chemically identified and assayed. At the present time very difficult questions have been raised by the fact that the substances have been found in the tissues from some patients dead of cancer but not in others, sample of 67 human livers, ...
متن کاملIn Cedar Creek Bog, Minnesota Stratigraphic Distribution of Lipoid Substances
The lake and bog deposits of Cedar Creek Forest, Isanti and Anoka counties, Minnesota, consist of a multiple-facies accumulation of marl, peat, copropel, and sapropel. Chromatographic analyses of the lipoid extracts of samples of the sediments show measurable amounts of saturated and aromatic hydrocarbons as well as large proportions of asphalts and polar lipoid compounds.

متن کاملFormation of carcinogenic substances during heating of foods
The formation of some selected carcinogens during cooking is associated with some certain types of foods. The heterocyclic amines are mainly found in meat and fish that are cooked at temperatures above 150°. Acrylamide is formed in foods containing asparagine and reducing sugars which are present in potatoes, cereals and similar products. The formation of acrylamide needs high temperatures simi...
متن کاملOn the Mechanism of Action of Carcinogenic Substances*
In the study of cancer one of the central problems is the elucidation of the pathogenesis of malignant tumors. The direction taken by such studies varies in accordance with prevailing points of view on the etiology of cancer. Since the discovery of carcinogenic compounds by Cook, Kennaway, and others ( i , 7), the theory of a chemical etiology of malignant tumors has been advanced. According to...
متن کاملReplication of low-level carcinogenic activity bioassays.
Bioassay for carcinogenic activity of a number of epoxides, lactones, hydroperoxides, and peroxides was reported from the laboratory at New York University (2,3). The compounds were tested by skin application on mice, s.c. injection in mice and rats, and feeding and intratracheal instillation in rats. Another series of related compounds was more recently tested at Fels Research Institute by s.c...
