Bone composition and bone mineral density (BMD) of long bones of two raptor and one owl species were assessed. Right humerus and tibiotarsus of 40 common buzzards, 13 white-tailed sea eagles and 9 barn owls were analyzed. Statistical analysis was performed for influence of species, age, gender and nutritional status. The BMD ranged from 1.8 g/cm3 (common buzzards) to 2.0 g/cm3 (white-tailed sea eagles). Dry matter was 87.0% (buzzards) to 89.5% (sea eagles). Percentage of bone ash was lower in sea eagles than in buzzards and owls. Content of crude fat was lower than 2% of the dry matter in all bones. In humeri lower calcium values (220 g/kg fat free dry matter) were detected in sea eagles than in barn owls (246 g/kg), in tibiotarsi no species differences were observed. Phosphorus levels were lowest in sea eagles (humeri 104 g/kg fat free dry matter, tibiotarsi 102 g/kg) and highest in barn owls. Calcium-phosphorus ratio was about 2:1 in all species. Magnesium content was lower in sea eagles (humeri 2590 mg/kg fat free dry matter, tibiotarsi 2510 mg/kg) than in buzzards and owls. Bones of barn owls contained more copper (humeri 8.7 mg/kg fat free dry matter, tibiotarsi 12.7 mg/kg) than in the Accipitridae. Zinc content was highest in sea eagles (humeri 278 mg/kg fat free dry matter, tibiotarsi 273 mg/kg) and lowest in barn owls (humeri 185 mg/kg, tibiotarsi 199 mg/kg). The present study shows that bone characteristics can be considered as species specific in raptors.

The aim: to determine the initial indicators of bone mineral density in children and adolescents with fractures of long bones, to assess the status of vitamin D. Methods. We studied the data of densitometric and laboratory methods of studying 46 sick children (39 (84.8%) boys and 7 (15.2%) girls) with long bone fractures at the age from 6 to 18 years. Bone mineral density was assessed by the method of dual-energy X-ray absorptiometry on a bone densitometer using the Eurasian regulatory database. Results. In 9 sick children with fractures, osteopenia of the I degree was revealed, in one patient - osteopenia of the II degree, in 5 patients - osteoporosis of the I degree, in the remaining 31 children the indicators of bone mineral density corresponded to normal values. Low calcium levels in 56.4% of boys and 57.1% of girls, along with increased alkaline phosphatase activity in 94.8% of boys and 100% of girls, testified to impaired bone formation. The results showed that 61.5% of boys were deficient and 57.1% of girls were deficient in vitamin D. Conclusion. Low bone mineral density, the presence of hypovitaminosis D in children and adolescents with low-energy fractures, given the importance of these indicators for fracture healing, require correction of the revealed violations: the choice of more gentle treatment methods, the appointment of adequate drug therapy, dynamic monitoring of the effectiveness of the prescribed therapy, and in children with a confirmed diagnosis of osteoporosis - studies of bone mineral density in dynamics. Key words: bone mineral density, low-energy fractures of long bones, hypovitaminosis D, osteoporosis, fractures in children and adolescents, Uzbekistan.
