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.

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

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 ...

The effect of insulin on bone resorption
Calcified Tissue Research, 1973the administration of crystalline insulin to thyroparathyroidectomized rats raised their calcium and phosphorus plasma levels. The plasma calcium gave a linear response between 31 and 250 mU of insulin/100 g body weight. The slope obtained is not significantly different from that obtained with parathyroid extract.

Mechanisms involved in bone resorption
Biogerontology, 2002Osteoclasts, which are present only in bone, are multinucleated giant cells with the capacity to resorb mineralized tissues. These osteoclasts are derived from hemopoietic progenitors of the monocyte-macrophage lineage. Osteoblasts or bone marrow-derived stromal cells are involved in osteoclastogenesis through a mechanism involving cell-to-cell contact

Immunoreactive collagenase and bone resorption
Biochimica et Biophysica Acta (BBA) - General Subjects, 19811. Active mouse bone collagenase is excluded from its inhibitory antibody by preincubation of that antibody with various forms of inactive enzyme, e.g. 'procollagenase', some collagenase-inhibitor complexes or partially denatured or degraded collagenase. This property allows the detection of several enzymatically inactive forms of collagenase. 2.

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.

In the present paper a model for the resorption of bone, such as that observed at the interface between surgical implants and bone tissue, is developed. While there are many previous studies where models for bone remodelling calculations are proposed, these have been based on the stress or strain state of the bone tissue itself as the driving force for

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 ...

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
