Analysis of the diagnostic presentation profile, parathyroidectomy indication and bone mineral density follow-up of Brazilian patients with primary hyperparathyroidism BJMBR
Oliveira,U.E.M.; Ohe,M.N.; Santos,R.O.; Cervantes,O.; Abrahão,M.; Lazaretti-Castro,M.; Vieira,J.G.H.; Hauache,O.M..
Primary hyperparathyroidism is an endocrine disorder with variable clinical expression, frequently presenting as asymptomatic hypercalcemia in Western countries but still predominantly as a symptomatic disease in developing countries. The objective of this retrospective study was to describe the diagnostic presentation profile, parathyroidectomy indication and post-surgical bone mineral density follow-up of patients with primary hyperparathyroidism seen at a university hospital. We found 115 patients (92 women, median age 56 years) with primary hyperparathyroidism diagnosed during the last 20 years. We defined symptomatic patients based on the presence of any classical symptom affecting bone, kidney or the neuromuscular system. Surgical criteria followed...

Bone densitometry and calcium serum levels in chickens treated with filtered or unfiltered water Rev. Bras. Ciênc. Avic.
Amoroso,L; Baraldi,ASM; Barreiro,FR; Pacheco,MR; Alva,JCR; Soares,NM; Pacheco,LG; Melaré,MC.
The aim of this study was to evaluate whether the drinking water of the School of Agricultural and Veterinary Sciences, UNESP, Jaboticabal, Brazil, affected bone mineral density and serum calcium levels of 14-, 21-, and 45-day-old broilers. Bone mineral density (BMD) of the tibiae was assessed using optical densitometry radiographic technique and serum calcium levels. Tibial BMD increased as broilers aged, and achieved its peak at 45 days of age. It was higher in the distal epiphysis of the birds that ingested filtered water (p<0.05) compared with those supplied with unfiltered water. Therefore, it is concluded that filtered water promoted better bone quality in relative to those ingested unfiltered water.

Bone mineral density in Brazilian men 50 years and older BJMBR
Zerbini,C.A.F.; Latorre,M.R.O.; Jaime,P.C.; Tanaka,T.; Pippa,M.G.B..
Bone mineral density (BMD) in the lumbar spine (LSBMD), femoral neck (FNBMD) and whole body (WBBMD) and whole body tissue composition were evaluated in 288 Brazilian men 50 years and older, 80% white and 20% Mulattoes. Age was inversely correlated with WBBMD (r = -0.20) and FNBMD (r = -0.21) but not with LSBMD (r = 0.03). Body mass index and weight showed a strong positive correlation with WBBMD (r = 0.48 and 0.54), LSBMD (r = 0.37 and 0.45) and FNBMD (r = 0.42 and 0.48). Correlation with height was positive but weaker. No significant bone loss at the lumbar spine level was observed as the population aged. FNBMD and WBBMD decreased significantly only in the last decade (age 70-79) studied. BMD was higher for Brazilian men as compared to Brazilian women at...

Bone mineral density in young women of the city of São Paulo, Brazil: correlation with both collagen type I alpha 1 gene polymorphism and clinical aspects BJMBR
Barros,E.R.; Kasamatsu,T.S.; Ramalho,A.C.; Hauache,O.M.; Vieira,J.G.H.; Lazaretti-Castro,M..
Osteoporosis is a multifactorial disease with great impact on morbidity and mortality mainly in postmenopausal women. Although it is recognized that factors related to life-style and habits may influence bone mass formation leading to greater or lower bone mass, more than 85% of the variation in bone mineral density (BMD) is genetically determined. The collagen type I alpha 1 (COLIA1) gene is a possible risk factor for osteoporosis. We studied a population of 220 young women from the city of São Paulo, Brazil, with respect to BMD and its correlation with both COLIA1 genotype and clinical aspects. The distribution of COLIA1 genotype SS, Ss and ss in the population studied was 73.6, 24.1 and 2.3%, respectively. No association between these genotypes and...

Densitometric Analysis of the Human Ulna International Journal of Morphology
Aguado-Henche,S; Clemente de Arriba,C; Carrascosa-Sánchez,J.
This study describes the distribution of the normal bone mass in the mature human ulna, as knowledge of distribution may provide information to orthopaedic surgeons for the treatment of such fractures while advancing the understanding of the responses of osteosynthesis elements during bone repair. A random sample of 41 dry ulnas was studied with a DXA system using a Norland XR-26 densitometer. Two projections were performed, lateral and antero-posterior. In both projections five regions of interest (ROI) were selected: proximal (ROI 1), proximal-intermediate (ROI 2), intermediate (ROI 3), distal-intermediate (ROI 4) and distal (ROI 5). All statistical calculations were performed using Stat graphics Plus (version 5.1) and SPSS (version 15.0). Bone mineral...

Determination and padronization of normal values of bone mineral density (BMD) of the acessory carpus bone in young Thoroughbred horse using optical densitometry in radiographic image Braz. J. Vet. Res. Anim. Sci.
Vulcano,Luiz Carlos; Santos,Flavio Augusto Marques dos.
The bone mineral density (BMD) of the accessory carpus bone was measured (in aluminum milimeters - mmAl) in 12 female and 12 male thoroughbred horses aging from 12 months old until the moment of complete closure of the radio distal epiphysis, using optical densitometry in radiographic images. Evaluation was made using a software specially developed for optical density measurement in X-ray films, containing the radiographic image of the accessory carpus bone, the region of soft parts adjacent to the accessory carpus and the degrees of an aluminum stepwedge, used to measure BMD value (average of the interest region established on the accessory carpus bone corresponding to the value on the stepwedge in milimeters). BMD values did not show differences between...

Electrical field stimulation improves bone mineral density in ovariectomized rats BJMBR
Lirani-Galvão,A.P.R.; Bergamaschi,C.T.; Silva,O.L.; Lazaretti-Castro,M..
Osteoporosis and its consequent fractures are a great social and medical problem mainly occurring in post-menopausal women. Effective forms of prevention and treatment of osteoporosis associated with lower costs and the least side effects are needed. Electrical fields are able to stimulate osteogenesis in fractures, but little is known about their action on osteoporotic tissue. The aim of the present study was to determine by bone densitometry the effects of electrical stimulation on ovariectomized female Wistar rats. Thirty rats (220 ± 10 g) were divided into three groups: sham surgery (SHAM), bilateral ovariectomy (OVX) and bilateral ovariectomy + electrical stimulation (OVX + ES). The OVX + ES group was submitted to a 20-min session of a low-intensity...

The aim of this study was to assess the measurement of bone mineral density (BMD) by quantitative computed tomography (QCT), comparing the relationships of BMD between QCT and dual-energy X-ray absorptiometry (DXA) and between QCT and radiographic absorptiometry (RA) in the metacarpal bone of Holstein dairy cows (n=27). A significant positive correlation was found between QCT and DXA measurements (r=0.70, P<0.01), and a significant correlation was found between QCT and RA measurements (r=0.50, P<0.01). We conclude that QCT provides quantitative evaluation of BMD in dairy cows, because BMD measured by QCT showed positive correlations with BMD measured by the two conventional methods: DXA and RA.

Experimental investigation of bone mineral density in Thoroughbreds using quantitative computed tomography OAK
YAMADA, Kazutaka; SATO, Fumio; HIGUCHI, Tohru; NISHIHARA, Kaori; KAYANO, Mitsunori; SASAKI, Naoki; NAMBO, Yasuo.
Bone mineral density (BMD) is one of the indications of the strength and health. BMD measured by quantitative computed tomography (QCT) was compared with that measured by dual energy X-ray absorptiometry (DXA) and radiographic bone aluminum equivalence (RBAE). Limbs were removed from horses that had been euthanized for reasons not associated with this study. Sixteen limbs (left and right metacarpals and metatarsals) from 4 horses were used to compare BMD as measured by QCT with those measured by DXA and RBAE. There was a strong correlation between BMD values measured by QCT and those measured by DXA (R2=0.85); correlation was also observed between values obtained by QCT and those obtained by RBAE (R2=0.61). To investigate changes in BMD with age, 37 right...

Glycosaminoglycans and vitamin C in ovo feeding affects bone characteristics of chicks R. Bras. Zootec.
Santos,Elaine Talita; Sgavioli,Sarah; Castiblanco,Diana Maryuri Correa; Domingues,Carla Heloísa de Faria; Quadros,Thays Cristina Oliveira de; Borges,Liliana Longo; Petrolli,Tiago Goulart; Baraldi-Artoni,Silvana Martinez.
ABSTRACT Different levels of glycosaminoglycans (chondroitin sulfate and glucosamine sulfate) and vitamin C were injected in ovo to determine whether additive use influences the incubation parameters and bone characteristics of posthatch chicks. Hatchability was not affected by addition of glycosaminoglycans and vitamin C in ovo. However, chicks that received 4 μg additive showed 2.86% reduction in total mortality when compared with chicks from non-injected eggs. Moreover, tibia area and femur bone mineral density increased in chicks from eggs injected with 2.16 and 6.00 μg of additive, respectively. In ovo feeding with glycosaminoglycans and vitamin C can benefit bone development in embryos and reduce total mortality during the incubation period.

High-impact exercise in rats prior to and during suspension can prevent bone loss BJMBR
Yanagihara,G.R.; Paiva,A.G.; Gasparini,G.A.; Macedo,A.P.; Frighetto,P.D.; Volpon,J.B.; Shimano,A.C..
High-impact exercise has been considered an important method for treating bone loss in osteopenic experimental models. In this study, we investigated the effects of osteopenia caused by inactivity in femora and tibiae of rats subjected to jump training using the rat tail suspension model. Eight-week-old female Wistar rats were divided into five groups (n=10 each group): jump training for 2 weeks before suspension and training during 3 weeks of suspension; jump training for 2 weeks before suspension; jump training only during suspension; suspension without any training; and a control group. The exercise protocol consisted of 20 jumps/day, 5 days/week, with a jump height of 40 cm. The bone mineral density of the femora and tibiae was measured by double...

Hydrogen Peroxide Induced Oxidative Damage on Mineral Density and Mechanical Properties of Bone BABT
Cicek,Ekrem; Cakmak,Enes.
ABSTRACT Hydrogen peroxide is a common reactive oxygen species involved in the catalytic mechanism though it is toxic to cells due to its oxidative nature. This work investigates the effects of hydrogen peroxide induced oxidative damage on bone mineral density and mechanical properties of bone which is primarily a composite material composed primarily of collagen fibers and biominerals. Sheep leg bones were exposed to hydrogen peroxide for a week. Bone mineral density was measured by using dual energy X-ray absorptiometry. Compressive modulus tests were applied to bone in order to determine mechanical properties. Our study shows that the hydrogen peroxide induced oxidative stress has negative effects on bone mineral density and stiffness. We observed...

Pereira,F.A.; Castro,J.A.S. de; Santos,J.E. dos; Foss,M.C.; Paula,F.J.A.
Data about the impact of bariatric surgery (BS) and subsequent weight loss on bone are limited. The objective of the present study was to determine bone mineral density (BMD), bone remodeling metabolites and hormones that influence bone trophism in premenopausal women submitted to BS 9.8 months, on average, before the study (OGg, N = 16). The data were compared to those obtained for women of normal weight (CG, N = 11) and for obese women (OG, N = 12). Eight patients in each group were monitored for one year, with the determination of BMD, of serum calcium, phosphorus, magnesium, parathyroid hormone, 25-hydroxyvitamin D, insulin-like growth factor-I (IGF-I) and osteocalcin, and of urinary calcium and deoxypyridinoline. The biochemical determinations were...
