Abstract
Summary
1) Weanling, male, albino mice were more resistant to the skeletal effects of diets containing sweet peas or β-aminopropionitrile (BAPN) than were rats. They also showed a much greater individual variation in susceptibility to the skeletal effects of such diets. At sufficiently high levels of BAPN, however, both skeletal and aortic lesions occurred. The microscopic changes occurring in the aorta are described in detail. 2) Paraphymosis also occurred, but the paralysis and urinary retention often seen in rats receiving similar diets were not observed.
