Biostatistics of Ames-Test Data
1980In 1976, Matter stated with regard to the problem of interpreting mutagenicity test results: “Although most environmental compounds can be expected to produce either negative or ‘weak’ effects, there seems to be no scientific work available today that deals with the statistical handling of such results.

Hintergrund und Fragestellung. Die Inzidenz maligner Tumoren des Kopf-Hals-Bereichs steigt weltweit an. Hauptrisikofaktoren sind der chronische Tabak- und Alkoholabusus. Durch die Erkennung von Hochrisikopatienten konnen fruhzeitig diagnostizierte Tumoren mit guten Heilungsaussichten behandelt werden.

The incidence of squamous cell carcinomas in the upper aerodigestive tract has increased worldwide. The main risk factors are chronic tobacco and alcohol consumption. The detection of high-risk persons is important because early diagnosis of these tumors provides a good chance for permanent healing.

The Salmonella (Ames) Test for Mutagenicity
Current Protocols in Toxicology, 1999AbstractThe Ames test is a widely accepted short‐term assay for detecting chemicals that induce mutations in the DNA of organisms. The assay is a reverse mutation assay that detects the mutational reversion of his‐dependent Salmonella to his‐independent colonies.

Das Ziel dieser Studie war, den anti-/mutagenen und anti-/oxidativen Effekt der lebensmittelrelevanten Pflanzenteile des „Pannonischen Crocus sativus austriacus“ (Klingenbach/Siegendorf, Bgld) im Ames-Test an zwei verschie-denen Salmonellen-Stämmen (TA98, TA102) gegenüber den Mutagenen TNFone, AFB+S9 und PHiP+S9 zu testen.

Ames mutagenicity tests of overheated brewed coffee
Food and Chemical Toxicology, 1984Five kinds of coffee samples were prepared from a commercial drip-grind coffee in order to examine the mutagenicity of brewed coffee using the Ames test. The samples prepared were a thick coffee syrup, coffee solid residues, dichloromethane and ethanol extracts of solid residues, a dichloromethane extract of a distillate from normally heated brewed ...

Modified suspension Ames test for testing proteinaceous substances: An initial step
Food and Chemical Toxicology, 1994The basic Salmonella/microsome assay (Ames test) is a valuable primary tool by which to discriminate mutagens from non-mutagens. For a variety of chemical test substances this test is easily conducted according to international guidelines for genotoxicity testing.

Use of the Ames test in toxicology
Regulatory Toxicology and Pharmacology, 1985The Salmonella/microsome assay (Ames test) is one of the most widely used short-term tests. Despite the ubiquitous presence of this assay and the large number of chemicals tested, there is still controversy over the value of Salmonella/microsome assay results in risk assessment.
