title: Abnormal lymphocyte responses in residents of a town with a cluster of Hodgkin's disease.
abstract: A time-space aggregate of Hodgkin's disease was observed in a small town. A large elevator for the storage of navy beans was located in the residential area of the town. Lymphocytes of town residents compared to those of non-residents showed increased levels of transformations when challenged with extracts of navy beans. A phytohaemagglutinin from navy beans with the ability to stimulate lymphocytes was isolated and characterized. A hypothesis concerning a connection between this cluster of Hodgkin's disease and the abnormal lymphocyte responses to navy-bean phytohaemagglutinin is discussed.
