Bone mineral densities in normal Bangladeshi women
fracture. Several chronic medical conditions, medications, and life style factors affect bone mineral accrual. This study aims to evaluate the bone mineral densities and hip axis lengths in the local population. Materials and Methods: 336 normal Bangladeshi women age ranges 20 to 70 years had evaluation of their bone mineral densities (BMDs) by means of dual X-ray absorptiometry (DXA). Results:...
متن کاملBone Mineral Quality
The main function of bone is to promote locomotion and protection of vital organs. Bone is also an important mineral ions reservoir, essential to maintain phosphocalcic homeostasis. Bone mineral is a calcium phosphate named “apatite”, which form naturally in the Earth’s crust (Wopenka & Pasteris 2005). Compared to others minerals, apatite is more “tolerant” and is very accommodating to chemical...
متن کاملAbnormal Bone Mineral Maturation
chronically uremic but nonacidotic rats with normocalcemia and hyperphosphatemia revealed smaller apatite crystals and an increase in the X-ray amorphous mineral fraction when compared to age-matched, pair-fed control animals, indicating less advanced mineral maturation in the uremic animals. Studies in animals with varied degrees of chronic renal insufficiency revealed a progression of the bon...
متن کاملBone and Mineral Metabolism
Background: Evidence suggests that vitamin D status in adults is positively associated with calcium absorption fraction and inversely associated with serum PTH. The objective of this study was to evaluate the relationships among vitamin D status, PTH, and calcium absorption in midpubertal boys and girls. Methods: Calcium absorption was measured by using a stable isotope method in 93 young adole...
متن کاملBone Mineral Measurements.
The accurate measurement of bone mineral density using noninvasive methods can be of value in the detection and evaluation of primary and secondary causes of decreased bone mass. This includes primary osteoporosis and secondary disorders, such as hyperparathyroidism, osteomalacia, multiple myeloma, diffuse metastases, and glucocorticoid therapy or intrinsic excess.By far, the largest patient po...
