Abstract:

A large experiment to study the effect of diet and various additives on the hamster, especially with regard to the incidence of arthritis and the condition of teeth and bones, was begun in 1957. Since it has been shown that the hamster normally is 1 susceptible to a spontaneous osteoarthritis, 2 has teeth that are softer than those of a rat hence more prone to caries, and 3 has less dense and more brittle bones than the rat it seemed a good animal for such an experiment. There were 16 different treatments involving diet and exercise. In addition both sexes were used on each treatment and these in turn were subdivided on the basis of 3 levels of fluorine in the drinking water at the level of 0, 1 and 10 ppm. There were in effect 96 different variables present. At death the animals were x-rayed, autopsied, soft tissues x-rayed and saved in 10 formalin. The teeth were cleaned and examined. Carcasses and organs were examined the long bones and joints for arthritis and other pathology was studied. The x-ray pictures were examined for fractures of the long bones and for osteoporosis. Organ pictures were checked for lung disease and any possible calcification. These data have not yet been completely assembled. Author
