Currently available osteoporosis treatment include antiresorptives and/or anabolic agents. Studies in animals have shown that beta-hydroxy-beta-methylbutyrate (HMB) administration affects anabolically bone tissue metabolism and improves morphological, densitometric and mechanical properties of bones in axial and appendicular skeleton. Thus, the aim of the study was to present first data on effects of 61-week treatment with HMB on volumetric bone mineral density (vBMD) of lumba...

Considering limited information available on skeletal system properties in foxes, the aim of this study was to determine morphological, geometrical and densitometric parameters of femur obtained from males and females. The study was performed on 1-year old male (n=5) and female (n=6) silver foxes. Right femur was isolated and its weight and length were measured. Using quantitative computed tomography (QCT) technique and Somatom Emotion Siemens apparatus, bone...

Methimazol is an antithyroid drug for treatment of hyperthyroidism. Methimazol inhibits the enzyme thyroperoxidase participating in thyroid hormone synthesis and reduces triiodothyronine (T3) and thyroxine (T4) blood concentrations. The study was performed to determine effects of 90-day long oral administration with methimazol on femur properties isolated from male Wistar rats. The first group (n=6) consisted of control rats. The experimental rat...

The aim of the study was to evaluate interrelationships between morphometric, densitometric and mechanical properties of mandible in Polish Merino sheep. Males (n=7) were kept to slaughter age of 5 months of life to obtain mandible. After the slaughter, morphological properties of the mandible such as bone weight and length were determined. Using quantitative computed tomography (QCT) technique and Somatom Emotion, Siemens apparatus, volumetric bone mineral density (v...

The aim of the study was to evaluate relationships between morphometric, densitometric and mechanical properties of tarsometatarsus in ostriches (Struthio camelus). Males (n=9) and females (n=15) were kept to slaughter age of 14 months of life to obtain left tarsometatarsus. Using computed tomography technique (Somatom Emotion, Siemens), volumetric bone mineral density (vBMD) of the trabecular (Td) and cortical bone (Cd) were measured. Areal BMD and ...

The aim of this study was to determine interrelationships between final body weight, bone-specific alkaline phosphatase (BAP), IGF1 and morphological, densitometric and mechanical properties of deciduous mandibular teeth isolated from seven healthy Polish Merino rams. Four incisors (I1–I4) and second premolar (P2) were obtained from 5-month-old sheep. Teeth were cleaned, weighed, and their length was measured. Mean volumetric tooth mineral...

The aim of the study was to evaluate time-related changes in serum concentration of bone tissue metabolism markers in Polish Large White male pigs. At birth, the piglets were divided into four groups. The first control group (n=7) received physiological saline i.m. (placebo). The second group (NanoCa group; n=7) were administered p.o. with nanopartical calcium (Ace Nano Calcium, NanoTechWorld, Pohang, Korea). The third group (Dex group; n=7) received...

The aim of the study was to evaluate relationships between morphometric, densitometric and mechanical properties of tibiotarsus in ostriches (Struthio camelus). 14-month-old males (N=15) and females (N=31) were slaughter to obtain left tibiotarsus. Using computed tomography technique (Somatom Emotion scaner, Siemens), volumetric bone mineral density (vBMD) of the trabecular (Td) and cortical bone (Cd), mean voulmetric bone mineral density (MvBMD) and...

The aim of the study was to evaluate effects of 6-month-long administration with nanopartical calcium on morphological and densitometric properties of axial skeleton in pigs subjected to osteoporosis induction with dexamethasone. Male newborn piglets (N=28) were divided after birth into four equal groups (control group receiving placebo, Dex group receiving dexamethasone, NanoCa group receiving orally nanopartical calcium and NanoCa/Dex group) receiving simultaneously...

The aim of this study was to determine morphological and densitometric parameters of mandible obtained from male and female silver foxes (Vulpes vulpes). The study was performed on 1-year-old males (n=7) and females (n=8). Mandible was isolated and subjected to morphological and densitometric analysis using quantitative computed tomography (QCT) method and Somatom Emotion Siemens apparatus (Siemens, Erlangen, Germany) equipped with Somaris/5 VB10B so...
