“…The animals were sacrificed by an overdose of anesthetic. The right femur and lumbar vertebrae L2–L5 were dissected for the measurements of bone mineral content and bone mineral density by dual‐energy X‐ray absorptiometry (DCS‐600; Aloka, Tokyo, Japan) according to the method of Tanaka et al (20) …”

Development of new methods for accelerating orthodontic tooth movement has been strongly desired for shortening of the treatment period. The rate of orthodontic tooth movement is dependent on the rate of bone resorption occurring in the compressed periodontium in the direction of orthodontic force applied to the tooth. In the present study, we examined the effects of continuous infusion of parathyroid hormone (

“…4 Although plain radiographs are the gold standard in following up distraction osteogenesis 6,15,29,38 they do not provide accurate information regarding the course of new bone formation because they are not quantitative. 3,26,33,36 The current authors decided to use DEXA, which is quantitative and has been used successfully in followup observations of distraction osteogenesis in animal models and in patients. 12,13,19,23,26,33 Observation and assessment of the regenerate is easy because the gap produced by distraction of the osteotomy is immediately definable on the images provided by DEXA.…”

“…Bone density was measured on Days 20,35,45, and 55 of the experiment, after the lengthening phase had been concluded to obtain a time-related assessment of mineralization. The most common method of analysis 19,36 was used, in which the region of interest is the area included between the osteotomy ends and the extensions of the neighboring cortices.…”

The effect of salmon calcitonin on the maturation of the regenerate bone was assessed in an experimental model in rabbits. Twenty-six New Zealand White male rabbits, approximately 5 months old and weighing 3 to 3.5 kg, were subjected to a mid-diaphyseal tibial osteotomy. After 5 days, the right tibia was lengthened gradually at a rate of 0.375 mm every 12 hours, for 10 days. Ten international units of salmon calcitonin were administered daily subcutaneously to the study group (14 animals), whereas the animals of the control group (12 animals) were injected with a placebo, for the duration of the experiment. The bone mineral density of the regenerate bone was assessed on Days 20, 35, 45, and 55 of the experiment, in both groups, using dual energy xray absorptiometry. No statistical significant difference was found in the dual energy xray absorptiometry measurements between the study and control groups regarding the change of the bone mineral density of the new bone relative to a preoperative baseline measurement. Characteristic time-related changes were observed in the bone mineral density of the regenerate bone during its maturation, which proved to be identical in both groups. It seems that the administration of calcitonin does not enhance regenerate bone mineralization rate and tendency during bone lengthening.

О биохимической природе этой формы хондродистрофий ничего не известно, если не считать сведений о различных отклонениях активности ряда ферментов, значение которых остается пока неясным [12,13].…”

случай сочетания ахондроплазии и гипоплазии гипофиза у мальчика 6 лет. Пациентам с ахондроплазией рекомендовано проведение магнитно-резонансной томографии гипофиза с целью выявления его возможной гипо-или аплазии. При наличии гипопитуитаризма у пациентов с ахондроплазией необходима соответствующая заместительная гормональная терапия.
