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...

The purpose of the present study was to examine the effect of 3-years of moderate multi-component exercise training on bone mineral density and bone mineral content in a female subject with osteoporosis. A 57-year-old postmenopausal woman, a known case of osteoporosis following an accident, participated in this study. Bone mineral density and bone mineral content was measured in the femoral nec...

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...

Autogenous bone graft is gold standard in treating bone defects, but it might have difficulty in corporation and rejection reaction. This study is to compare the effectiveness among freeze-dried xenograft, freeze-dried allograft, hydroxyapatite xenograft, and demineralized bone matrix xenograft as bone graft to fill bone defect in femoral diaphysis of white rabbit. Thirty male New Zealand white...

The basic aspects of bone tissue engineering include chemical composition and geometry of the scaffold design, because it is very important to improve not only cell attachment and growth but especially osteodifferentiation, bone tissue formation, and vascularization. Geistlich Bio-Oss (GBO) is a xenograft consisting of deproteinized, sterilized bovine bone, chemically and physically identical t...

1. The influence of pregnancy, lactation and weaning on bone mineral density in healthy women was investigated during a 2 year prospective study of 59 pregnant and lactating women from the 18th week of gestation. 2. Bone mineral density was measured by dual energy X-ray absorptiometry at the non-dominant radius ultra distally and more proximally in the 18th and 37th weeks of gestation, and 0, 3...

introduction : osteoporosis is characterized by low bone density and increase in the risk of fracture. because in pregnancy and lactation there are many factors which influence bone mineral density, we sought to assess whether the accumulation of multiple pregnancies and the accompanying extended periods of lactation were a risky factor for low bone mineral density and osteoporosis. materials &...

The aim of this study was to evaluate whether the use of enamel matrix proteins with or without the use of deproteinized bovine bone influences bone formation when used as an adjunct to guided bone regeneration (GBR). Twenty rats, divided into four groups of five animals each, were used in this study. Group A1: A hemispherical PTFE capsule was placed empty on the lateral aspect of the mandibula...

OBJECTIVE To investigate whether a postoperative weight-bearing regimen affects changes in bone mineral density and body composition after uncemented total hip arthroplasty, and to investigate the changes over a 5-year period after the surgical procedure. DESIGN Secondary analysis of a previous randomized controlled trial. METHODS A total of 39 patients were randomized to immediate full wei...
