background: revealing data on the role of vitamin d and calcium supplementation in bone health has led some to suggest that vitamin d and calcium treatment could also play a role in protecting bone against microgravity-induced mineral loss. objectives: the aim of the present study was to investigate the effects of vitamin d and calcium administration on microscopic and densitometric changes of ...

the aim of current study was to determine the effects of vitamin c on bone mineral density (in terms of osteoporosis), eggshell quality and investigation of correlation between these factors in laying hens reared under normal condition. one hundred and ninety two 24 - weeks - old laying hens diet was supplemented with 4 levels of vitamin c (0, 250, 500 and 750 mg/kg diet). the experimental desi...

Lumbar spine bone mineral density in a cross sectional study of healthy subjects increased by 0.012 and 0.016 g/cm2/year in boys and girls respectively between 5 and 11 years of age. These rates increased five-fold in girls and threefold in boys between the ages of 11 and 13 years as a result of the bone mineral content increasing more rapidly than the coronal area at this age. By the age of 11...

background: we compared bone mineral density (bmd) in patients with relapsing-remitting multiple sclerosis (rrms) on interferon with that of patients with relapsing-remitting multiple sclerosis (rrms) who were not receiving interferon and healthy age- and sex-matched controls. methods: overall, 30 patients with rrms on interferon (treated patients), 30 patients with rrms but not receiving inter...

background: multiple sclerosis (ms) is a demyelinating disease which can cause many disabilities for the patient. recent data suggests that ms patients have higher risk for osteoporosis. this study was performed to investigate if the osteoporosis prevalence is higher in ms patients and to determine the possible factors affecting bone mineral density (bmd). methods: 51 definite relapsing-remitti...

investigations regarding the relationship between bone mineral density (bmd) and thyroid function tests even in the normal range are limited. therefore, the present study was conducted to investigate the relationship between bmd with thyroid function tests in elderly people. this study is a part of a prospective study about health status of the elderly people in amirkola city (ahap) which is on...

the objective of this study was to evaluate the effect of accell connexus(®) on the quality and rate of healing in experimental defects of rabbit calvarium compared to bio-oss®.twelve 2.5-3.5 kg weighing new zealand white rabbits were used. three defects (3×6 mm) were created in the cranium of the animals subsequently filled with accell connexus(®), bio-oss® or served as controls. the animals w...

BACKGROUND To investigate the effect of intra-articular injection of Chitosan (Cs) added to hyaluronic acid (HA) on subchondral bone during osteoarthritis (OA), microarchitectural parameters and mineral density were measured in a rabbit model of early OA. A novel hybrid hydrogel adding reacetylated Cs of fungal origin to HA was compared to high molecular weight HA commercial formulation. METH...

We thank Reviewer #1 for his constructive comments. * We agree that BV/TV often correlates with measurements of BMD. However, bone volume and bone mineral density represent different aspects of the bone, and do not necessarily have to correlate. Bone mineral density evaluates the mineral content of the bone, while bone volume is the space occupied by the bone, regardless of the mineral content....

1. Bone mineral content of the second, third and fourth lumbar vertebrae was determined in normal women and women with clinical osteoporosis by using dual-photon (153Gd) absorption. 2. A cross-sectional study of 70 normal (aged 19-88 years) showed a bone loss of 44% from the age of around 34 years throughout life. 3. Longitudinal data from 59 normal women confirmed that the vertebral bone loss ...
