Ultrastructure of cartilage.
reported that the nodule in Still's disease often resembled that of rheumatic fever histologically; this was based on biopsies of eleven cases compared with 57 with rheumatic fever and 22 with adult rheumatoid arthritis. We now report a small series of six children followed for 3 to 5 years, where multiple small nodules as seen clinically in rheumatic fever were the predominant clinical feature...
متن کاملChondrocyte ultrastructure in adult human articular cartilage.
Age changes in the ultrastructure of articular chondrocytes have been studied in detail in mice (Silberberg, Silberberg, and Feir, 1964) and in rabbits (Davies, Barnett, Cochrane, and Palfrey, 1962; Barnett, Cochrane, and Palfrey, 1963). Less has been published concerning the influence of age on cellular ultrastructure in human articular cartilage. This is due partly to the scarcity of suitable...
متن کاملUltrastructure of calcified cartilage in the endoskeletal tesserae of sharks.
The tesserate pattern of endoskeletal calcification has been investigated in jaws, gill arches, vertebral arches and fins of the sharks Carcharhinus menisorrah, Triaenodon obesus and Negaprion brevirostris by techniques of light and electron microscopy. Individual tesserae develop peripherally at the boundary between cartilage and perichondrium. An inner zone, the body, is composed of calcified...
متن کاملUltrastructure of chondrocytes in osteoarthritic femoral articular cartilage.
BACKGROUND Osteoarthritis (OA) is a common problem in elderly, but it is not an inevitable feature of ageing. About 80-90% of individuals of both sexes have radiographic evidence of OA by the time they reach an age of 65. But not all of them have the symptoms like pain and decreased joint motion. OBJECTIVE The objective of the present study was conducted to find out whether the osteoarthritic...
متن کاملThe ultrastructure of cartilage formation from neonatal skeletal muscle in vitro.
Histological changes in cultured neonatal skeletal muscle tissue at the early stage of cartilage induction by syngeneic insoluble bone matrix gelatin (BMG) containing bone morphogenetic protein were examined by light and electron microscopy. Minced skeletal muscle was cultured on hemicylindrical pieces of BMG for 14 days. Chondroblasts first appeared in the crevices of the BMG on Day 7 of the c...
