A method for obtaining the absolute number of each type of marrow cell in experimental aminals is described in detail. Absolute cell counts are given for the bone marrow and blood of two separate series of rats, one of 40 and the other of 41 animals. Some of the secular variations in cell counts coincided with a change in ...

The technique of photon absorptiometry, as described by Cameron and others (1-4), is used to obtain a measure of bone density. This measure, based on data derived from the transmission scan of /sup 125/I, clearly relates to the degree of mineralization of the bone, and hence is termed bone mineral content (BMC). Although BMC is a ...

The distribution of fluoride within the femur, metacarpus, and mandible of wild deer from contaminated, and control ecosystems was determined. Absolute fluoride concentrations were found to be highest in the cancellous portions of the bones and insections with the largest surface area to weight ratio. The relationship of the relative fluoride levels within ...

A model of weightlessness in which the hindlimbs of rats are elevated by their tails at a 40 degrees angle to unload the hindlimbs while maintaining normal weight bearing on the forelimbs has been used to simulate certain conditions of space flight. When we used this model in growing rats, we found that growth in bone weight ceased by 1 week in the ...

Adynamic (or aplastic) bone disease is a bone histologic pattern characterized by decreased bone formation rate, low cellularity, and normal or decreased osteoid thickness. It was first described in symptomatic patients undergoing dialysis who were overloaded with aluminum because of contaminated dialysate or ...

When bone is remodeled during the growth of a given size bone to a larger size, some bone is resorbed and some is deposited. Much of the resorbed bone mineral, calcium, can be reutilized during bone formation. The net and absolute effects of normal ...

Dogs were classified into a number of disease categories according to hematological, cytological and serochemical changes. Aspiration and core bone marrow biopsies were examined in 128 dogs in the various disease categories and compared to marrow samples in 36 dogs which appeared clinically normal. Differential cell counts on bone ...

Contamination of the dialysis solution with trace amounts of aluminum and long-term use of aluminum-based phosphate binders have led to increased body burden of aluminum in patients with end-stage renal disease. A significant clinical problem associated with aluminum-overload is the early diagnosis of aluminum-induced dialysis dementia and osteomalacic osteodystrophy. There are few, if any, blood ...

The aim of this study was to identify the clinical parameters of absolutely poor-prognosis patients with chronic critical limb ischemia (AP-CLI). Sixteen no-option CLI patients with arteriosclerosis obliterans: ASO (nine) and non-ASO patients (seven) treated with bone marrow-mononuclear cell implantation (BMI) were analyzed. There were three AP-CLI ...

From international conference on bone mineral measurement; Chicago, Illinois, USA (12 Oct 1973).

Total-body calcium was measured in 40 adult women by total-body neutron activation analysis (TBNAA). Procedures for normalizing the absolute calcium measurements for the parameters of size and age were developed in order to effect a direct comparison of women of age 30 to 78 yr. The normal total-body calcium (TB/sub Ca/) for an ...

In clinical applications, ultrasound parameters are measured as an average value over a region of interest (ROI) or as a value at a single measurement point. Due to natural adaptation to loading conditions, trabecular bone is structurally, compositionally and mechanically heterogeneous and anisotropic. Thus, spatial variation of ultrasound parameters within ROI may contain ...

Objective-To compare in vitro axial compression, abaxial compression, and torsional stiffnesses of intact and plated radii from small- and large-breed dogs. Sample-Radii from 18 small-breed and 9 large-breed skeletally mature dogs. Procedures-3 groups were tested: large-breed dog radii plated with 3.5-mm limited-contact dynamic compression plates (LCDCPs), small-breed dog radii plated with 2.0-mm ...

Murine platelet production is normally supported by high-ploidy bone marrow megakaryocytes without significant contribution from splenic megakaryocytes with predominantly low-ploidy levels. We produced sustained bone marrow ablation using radiostrontium, and examined the processes by which splenic platelet production is initiated and ...

From annual meeting of American Orthopaedic Association; Hot Springs, Virginia 621 Jun 1971). Thirty-four additional cases of sarcoma developing in previously irradiated bone are documented, bringing the total Mayo Clinic experience in sarcoma appearing after radiation therapy to fifty-five instances. The sarcomas arose in normal ...

Bone mineral density (BMD) is a strong predictor of fracture, yet most fractures occur in women without osteoporosis by BMD criteria. To improve fracture risk prediction, the World Health Organization recently developed a country-specific fracture risk index of clinical risk factors (FRAX) that estimates 10-year probabilities of hip and major osteoporotic fracture. Within ...

Studies on the mechanism of anemia in mice of genotype S1/S1/sup d/ have implicated the hematopoietic stroma (the hematopoietic inductive microenvironment, HIM) rather than hematopoietic stem cells as the site of the defect. Using methylcellulose-supported bone marrow culture systems, we have observed, in addition to classical hematopoietic colonies, the formation of surface ...

Loss of bone mineral of the skeleton in renal disease can be measured directly by total body neutron activation analysis (TBNAA), and also by an absorptiometric technique applied to the appendicular skeleton (radius). In the present study the results of these two techniques are compared in 25 patients with renal insufficiency, 53 patients with end-stage renal failure ...

As preliminary treatment, x rays or Co/sup 60/ gamma radiation (1000-- 15000 r) and cytostatic drugs were given to the cases ...

Low birth weight and poor childhood growth program a variety of adult diseases including bone disorders such as osteoporosis. We have previously reported that offspring born small, as a result of uteroplacental insufficiency, have shorter femurs, lower bone mineral content and a bone strength deficit as adults. The aim of this study ...

Under physiological conditions, the innate immune cells derived from myeloid lineage absolutely outnumber the lymphoid cells. At present, two theories are attributed to the maintenance of haemopoiesis: the asymmetric cell division and the bone marrow hematopoietic microenvironment or "niche". However, the former only explains the self-renewal of ...

Growth failure is common in children with chronic kidney disease, and successful treatment is a major challenge in the management of these children. The aetiology is multi-factorial with "chronic kidney disease-metabolic bone disorder" being a key component that is particularly difficult to manage. Parathyroid hormone is at the centre of this mineral imbalance, consequent ...

We have demonstrated that absolute values of bone lead concentrations can be established from well-known physical constants. The correlation between EDTA test results and tibial lead measured by three different groups using three different methods is found, after normalization to common units, to lie on a common curve that, on average, ...

Radionuclide bone imaging was performed in a rabbit model to observe the course of fracture healing and to establish criteria for distinguishing nonunion and delayed healing from normal healing. Sequential gamma-camera images (with pinhole collimator) were collected and subjected to computer analysis. Five groups were established: (a) ...

Radiological studies are the standard method to monitor fracture healing but they do not allow a timely assessment of bone healing. Biochemical markers react rapidly to changes in bone metabolism during fracture healing and could be an additional tool to monitor this process. The goal of this study was to observe changes in serum biomarkers and evaluate ...
