Ultrastructure of normal rat synovial membrane.

Remobilization Does Not Restore Immobilization-Induced Adhesion of Capsule and Restricted Joint Motion in Rat Knee Joints

“…The joint capsule is composed of two distinct layers: an external dense fibrous layer of the capsule and internal thin synovial membrane (Roy and Ghadially 1967). Though the importance of the joint capsule to the pathogenesis of the joint contracture is well accepted, the underlying changes within the joint capsule are not fully understood.…”

Submicroscopic Structure of the Human Synovial Membrane

“…The results of the author's studies are in accordance with data of Barland et al (1962), Roy (1966), Roy et al (1966), Roy (1967b, 1969), Maldyk et al (1974) and others as far as the human synovial membrane is concerned. Mitochondria differing in their appearance and cristae arrangement occur in the synovial membrane of the rabbit and rat, as was described by Wyllie et al (1964), Ghadially and Roy (1966), Roy and Ghadially (1967), Mitchell and Blackwell (1968), Cherney et al (1970), Wassilev (1972Wassilev ( , 1973Wassilev ( , 1975, Krey et al (1976), Watanabe et al (1976a, b).…”

As far as the arrangement of cells of the synovial membrane is concerned the author's findings are in accordance with data of Lever and Ford (1958) who were the first to observe parts of the synovial membrane uncovered by a continuous layer of cells (Fig.…”

“…In some cases they contain, besides granular material, also membranous structures originating probably from mitochondria. The frequent occurrence of secondary lysosomes in the cytoplasm of A cells of the synovial membrane was one of the causes why many authors considered this type of cells to b~ capable of phagocytosis (Ball et al 1964, Cochrane et al 1965, Adam 1966, Muirden 1966, Ghadially and Roy 1967, Luckenbill and Cohen 1967, Muirden and Senator 1968, Webb et al 1969, Bhawan et al 1973, Wassilev 1972, Bhawan and Roy 1974, Cchiu 1975, ,Biro 1974, Krey et al 1974, Johansson and Rejno 1976, Oryschak and Ghadially 1976a and others.…”
