Cortisone induced alterations of costal cartilage in single and in parabiosed rats

Abstract
Cortisone-treated Buffalo rats have been parabiosed with untreated controls of the same age. The optical and electron microscopy, including histochemistry, of costal cartilage of these rats has been compared with that in single cortisone treated rats, single controls, and control parabiosed with control rats, at 14 and 28 days after parabiosis.
