statement of problem: glucocorticoid-induced osteoporosis is characterized by a decrease in osteoblast numbers and a marked impairment of new bone formation. purpose: the ain of present study was to evaluate the effect of methylprednisolone acetate on bone metabolism and bone mineral density in rats. materials and methods: eighteen male sprague dawley rats (8 weeks old, weighting 180 gm) were r...

OBJECTIVE To investigate the relationship between total and segmental body fat, bone mineral density and bone mineral content in undergraduate students stratified according to nutritional status. METHODS The study included 45 male undergraduate students aged between 20 and 30 years. Total and segmental body composition, bone mineral density and bone mineral content assessments were performed ...

OBJECTIVE The aim of this systematic review was to investigate the influence of bone mineral density on the primary stability of dental implants. MATERIAL AND METHODS A search of health science databases (Cochrane Library, MEDLINE-PubMed, ISI Web of Knowledge, EMBASE, LILACS) and grey literature was performed, including papers published until January 2011. The main key words used were "bone d...

To identify the pattern of bone mineral density in postmenopausal women through retrospective study in 40 postmenopausal women using Dexa instrument in bones (L2 L4). Results with 15% of survey formula accuracy were found: mean of menopausal age was 53.25 years, normal bone mineral density 30%, osteopenia 52.5%, and osteoporosis 17.5%. A very strong relationship (r=0.547) and a significant rela...

Mutations in the HFE gene may be associated with increased tissue iron stores reflected in an elevated serum ferritin. With homozygous mutation C282Y, the increase in serum ferritin may be associated with tissue damage in the liver, pancreas, and pituitary and with a reduced bone mineral density. With heterozygous mutation C282Y, the degree of iron retention is less but information relating to ...

To investigate associations of lifestyle factors with bone mineral density among young men in Japan, we measured bone mineral density of the second metacarpal bone in 143 male university students, aged 18-22 years, by the computed X-ray densitometry. The subjects completed a lifestyle questionnaire including a quantitative food frequency questionnaire. Their mean+/-standard deviation of bone mi...

BACKGROUND Osteoporotic structural damage and bone fragility result from reduced bone formation and increased bone resorption. In a phase 2 clinical trial, strontium ranelate, an orally active drug that dissociates bone remodeling by increasing bone formation and decreasing bone resorption, has been shown to reduce the risk of vertebral fractures and to increase bone mineral density. METHODS ...

We studied the effects of grape seed proanthocyanidins extract (GSPE) given as a ratio of 3 mg in 100 g in a standard diet, on the tibial bone diaphysis in low-calcium fed rats. Measurements of bone density, mineral content, geometry, and bone strength using peripheral quantitative computed tomography (pQCT). Further, the whole tibia bones were tested for mechanical resistance using a material-...
