Abstract
The effects of lifetime treatment with dimethylaminoethanol on longevity and cryptogenic neoplasm formation were studied in females of two mouse sub-lines, the C3H/HeN which carries a germinal mammary tumor provirus and the C3H/HeJ(+) which also carries the exogenous mammary tumor virus. Administration in the drinking water of 10 mM dimethylaminoethanol to the C3H/HeN mice or 15 mM to the C3H/HeJ(+) mice did not result in significant differences between treated and untreated groups in average survival. No changes in age-related organ structure or morphology were observed with dimethylaminoethanol treatment, except for an apparent decrease in the amount of lipofuscin in the liver judged in histological sections. Among untreated C3H/HeJ(+) females, 89% developed neoplasms of the mammary gland, ovary, liver, lung and reticuloendothelial system, while the incidence was 88% in the treated mice. In C3H/HeN females, neoplasms of the mammary gland, ovary, liver, lung and lymphatic system occurred in 57% and in 60% of treated mice. Also, there was no statistically significant difference between control and treated animals in the age of onset or the type of specific neoplasms. Dimethylaminoethanol did not induce any neoplasms.
