title: Content and synthesis of nucleic acids in the cartilage in chondromalacia patellae.
abstract: The content and the synthesis of nucleic acids in chondromalacian, osteoarthritis and normal cartilage was compared. The chondromalacian cartilage differed from osteoarthritis in that the content of nucleic acids was less. Also, the cell density was less in chondromalacian than in normal cartilage as opposed to previous findings in osteoarthritis. The synthesis of DNA was greater in chondromalacian than in normal cartilage but less than in osteoarthritis. With regard to the RNA synthesis, however, the chondromalacian cartilage showed a higher rate than both normal and osteoarthritic cartilage.
