Nitrosomethylurethane

09/01/1982 - "Apart from the esophageal tumors induced only by nitrosomethylurethane at the higher dose, there was no significant difference in carcinogenic effectiveness between the methyl and ethyl nitrosourethanes."
01/01/1982 - "Nitrosomethylurethane and nitrosoethylurethane failed to induce tumors after greater than 60 weeks treatment. "
09/01/1981 - "Ultrastructure of pulmonary tumors induced in rats by N-nitrosomethylurethane."
05/01/1976 - "Nitrosoethylurethane appeared to be a little more potent than nitrosomethylurethane; all 12 animals in this group had squamous stomach tumors at death. "
05/01/1976 - "The rats given nitrosocarbaryl survived longer, but had as high an incidence of tumors (75%) as did rats given nitrosomethylurethane. "

06/01/1962 - "[Acute poisoning of rats with nitrosomethylurethane after oral application]."

09/01/1982 - "Almost all of the treated rats died with papillomas and carcinomas of the forestomach (non-glandular stomach), and the other induced tumors of significance were carcinomas and papillomas of the esophagus in rats given the 7 mg/ml dose of nitrosomethylurethane, both labeled and unlabeled. "

"

11/01/1993 - "Groups of 30 to 33 male F344 rats were given dietary 0.1% 8-nitroquinoline, dietary 0.4-0.2% 2-(2-furyl)-3-(5-nitro-2-furyl)acrylamide, an intragastric dose of 20 mg/kg body weight N-methyl-N'-nitro-N-nitrosoguanidine once a week, or 20 ppm N-methylnitrosourethane in the drinking water as a genotoxic carcinogen, or 2% butylated hydroxyanisole, 2% caffeic acid, 2% sesamol or 2% 4-methoxyphenol in the diet as a non-genotoxic carcinogen for 24 weeks.
