Carcinogenicity of sterigmatocystin

Food and Cosmetics Toxicology, 1968
Abstract The mycotoxin, sterigmatocystin, was administered to rats in doses of 0·15–2·25 mg/day by gavage or in the diet for 52 wk. Eight rats which received a high dose (1·5–2·25 mg/day) of sterigmatocystin died between wk 5 and 18, while 39 out of the 50 treated rats surviving to wk 42 eventually developed hepatocellular carcinoma. Of these, 31 had

Dietary Carcinogens and Anti-Carcinogens

Journal of Toxicology: Clinical Toxicology, 1984
The scientific understanding of cancer and degenerative disease is being aided by new methodologies which are now used to approach the problem of environmental and occupational carcinogens and anticarcinogens. This paper reviews these powerful new tools and relates them to "natural" mutagens and carcinogens in food.

Thresholds for carcinogens

Chemico-Biological Interactions, 2021
Current regulatory cancer risk assessment principles and practices assume a linear dose-response relationship-the linear no-threshold (LNT) model-that theoretically estimates cancer risks occurring following low doses of carcinogens by linearly extrapolating downward from experimentally determined risks at high doses.

BRACKEN CARCINOGENICITY

Reviews on Environmental Health, 1979
The study of bracken carcinogenicity affords an interesting example of the close alliance, with mutual benefit, between the work of veterinarians in the field and experimental research. On the one hand was the condition found in many parts of the world of bovine enzootic haematuria with uncertain aetiology and, on the other, the investigations ...

Carcinogens and Anticarcinogens

1986
There is the potential for major progress in the prevention of cancer in the next 5 or 10 years. In the short term, progress in the prevention of cancer depends on a better understanding of some of the risk factors and antirisk factors for the major human cancers.

Mutagens, Carcinogens, and Anti-Carcinogens

1982
Mutagens and carcinogens in the environment represent a potential hazard, and it is important to screen large numbers of compounds and mixtures of compounds to which humans are exposed. However, it is Impractical for both technical and monetary reasons to do the bulk of mutagen screening by using mammals.
