One of us, A. Miyazaki, has already reported on the reaction of the rabbit's spine to the long durated overwork, compelled by way of the method in the J. Journal of clinical and experiment medicine 25; 271, 1948. We have following up further and obtained the following results. The Experiments of longer duration and rather few times of exercise lead to the result that, intratrabecular resorption and hypertrophy of the trabeculae, not observed by former experiment, are remarkable. By the short durated and frequently repeated exercises, on the other hand, we observed the resorption of compact bones, hypertrophy of the trabeculare, new bone formation in the bone narrow, hindrance of the growth of epiphyseal cartilage and the partial necrosis of the epiphyseal ossicle.
