Resorption characteristics of bone and bone substitutes
Oral Surgery, Oral Medicine, Oral Pathology, 1964Abstract Resorption of ninety intramuscular implants of different types of bone and bone substitutes were studied radiographically in twenty-two adult mongrel dogs. On the basis of mean resorption time, the implants were resorbed in the following order: (1) plaster of Paris, (2) autogenous cancellous bone, (3) cathode-ray-sterilized canine cancellous

Stimulative effects of cadmium on bone resorption in neonatal pariental bone resorption
Toxicology, 1992Effects of cadmium on bone resorption were investigated using neonatal mouse parietal bone culture system. Cadmium at 0.5 microM and above stimulated hydroxyproline release as well as 45Ca release. As cadmium-stimulated bone resorption was inhibited by calcitonin, bone resorption induced by cadmium is osteoclast-mediated bone resorption.

Bone Resorption in Human Cholesteatomas
Annals of Otology, Rhinology & Laryngology, 1982In vivo studies of different aspects of bone resorption in human cholesteatomas are described in the immunodeficient “nude” mice. Cholesteatoma membranes were transplanted into the middle ear cavities of the mice. After 21–28 days, growth of cholesteatoma tissue could be demonstrated in 8 of 13 animals.

Molecular mechanisms of bone resorption
Journal of Cellular Biochemistry, 1995AbstractThis review focuses on osteoclast ontogeny and function, emphasizing three aspects. We describe how a combination of laboratory models available to study the cell plus examination of the osteopetroses, a family of sclerotic diseases of the skeleton, have yielded major insights into osteoclast ontogeny and function.

Bone Resorption of the Distal Clavicle
JAMA: The Journal of the American Medical Association, 1979History An abnormality of the distal left clavicle was identified on a routine chest film of a professional hockey player, and this was confirmed on a shoulder roentgenogram (Fig 1). He denied pain or weakness in the left arm. Diagnosis Traumatic osteolysis of the distal end of the clavicle. Comment The shoulder films (Fig 1 and 2) show resorption

Cortical Bone Resorption in Osteoporosis
Calcified Tissue International, 1997A study was made of 110 women: 35 healthy premenopausal, 40 healthy postmenopausal, and 35 women diagnosed as having postmenopausal osteoporosis. The postmenopausal women had similar ages and years since menopause (YSM). In all of the women, total bone mass was evaluated by dual-energy X-ray absorptiometry and metacarpal morphometry was evaluated by ...

Archives of Surgery, 1930
The earliest workers in bone were concerned with its resorption. Howship, 1 in 1815 and 1817, discussed physiologic and pathologic resorption, but others before him had already called attention to this subject. Later, Koelliker, 2 using the newer methods of histologic technic, applied himself especially to a study of physiologic resorption and ...

Particles and Periimplant Bone Resorption
Clinical Orthopaedics and Related Research, 2002There is compelling evidence that the most important factor in late periprosthetic bone resorption is an inflammatory reaction to debris. Based on results from several laboratories, it seems likely that opsonized particles activate the macrophage nuclear factor-kappa B signal transduction system via membrane receptors, leading to release of tumor ...

The Cellular Basis of Bone Resorption
Clinical Orthopaedics and Related Research, 1980The osteoclast is the major agent of bone resorption. Durang the last few years persuasive evidence has emerged from several sources which shows that the osteoclast is derived from the fusion of cells of the mononuclear phagocyte system. This fact makes a reevaluation of the pathophysiology of bone resorption necessary. The most plausible mechanism for

Immune Cells and Bone Resorption
1986The concept of interactions between cells of the immune system and bone in the control of bone turnover is far from new. The relationship between haematopoietic precursor cells and the osteoclast has long been recognised and studies on animals with congenital bone diseases such as osteopetrosis have identified defective components of the immune system ...
