title: The influence of corticosteriods on the normal and papain-treated epiphysial growth plate in the rabbit.
abstract: Children undergoing continuous corticosteroid therapy become stunted in height. The mechanism of this inhibition of natural growth has been investigated in the lower femoral epiphysial growth plate of young rabbits on daily corticosteroid. The growth plate became narrow: fewer cells in the germinative zone gave rise to short widely-spaced chondrocyte columns, each with a reduced number of mature and hypertrophic cells; the pattern of trabecular bone in the metaphysis was also disturbed. After even small doses these changes develop very rapidly, and therefore impose a threat to the growth of children receiving treatment with corticosteroids.
