Journal Article
Quantitative Evaluation of the Promotion by 2,3,7,8-Tetrachlorodibenzo-p-dioxin of Hepatocarcinogenesis from Diethylnitrosamine
TL;DR: It is demonstrated that TCDD is a potent promoting agent for hepatocarcinogenesis and a distinct phenotype heterogeneity of the foci was noted with a shift towards phenotypes exhibiting a greater deviation from normal liver when T CDD was given following DEN-partial hepatectomy.
Journal Article
Application of Quantitative Stereology to the Evaluation of Enzymealtered Foci in Rat Liver
TL;DR: Only by quantitating the number and size of the foci in relation to the three-dimensional volume of the tissue can one determine the validity of the proportionality of data from two-dimensional measurements to the total number of foci per volume of tissue.
Journal ArticleDOI
Studies on the hemorrhagic sweet clover disease iv. the isolation and crystallization of the hemorrhagic agent
TL;DR: A crystalline dimethyl other (C12H12O4(OCH2)2 with a melting point of 168-170° (physiologically inactive) has been prepared by methylation with diazomethane as mentioned in this paper.
Journal ArticleDOI
A method to quantitate the relative initiating and promoting potencies of hepatocarcinogenic agents in their dose-response relationships to altered hepatic foci.

TL;DR: Based on quantitative stereologic calculations, parameters for the estimation for the relative potency of chemicals as initiating or promoting agents have been established and may be useful as quantitative estimates of the potency of hepatocarcinogenic agents.
