Quantitative and qualitative studies dealing with histomorphometry of the bone tissue play a new role in modern legal medicine/forensic medicine and archaeozoology nowadays. This study deals with the differences found in case of humerus and metapodial bones of recent sheep (Ovis aries), goat (Capra hircus) and roe deer (Capreolus capreolus) specimens, both from a qualitative point of view, but mainly from a quantitative perspective. A novel perspective given by the fractal analysis performed on the digital histological images is approached. This study shows that the qualitative assessment may not be a reliable one due to the close resemblance of the structures. From the quantitative perspective (several measurements performed on osteonal units and statistical processing of data), some of the elements measured show significant differences among 3 species (the primary osteonal diameter, etc.). The fractal analysis and the lacunarity of the images show a great deal of potential, proving that this type of analysis can be of great help in the separation of the material from this perspective.

 Glucocorticoids and β2-adrenergic receptor agonists are the most commonly used drugs in the treatment of asthma. Both therapies are potentially dangerous to the skeletal system. The aim of the present study was to investigate the effects of fenoterol, a β2-receptor agonist, on the development of bone changes induced by glucocorticoid (prednisolone) administration in mature male rats. The experiments were carried out on 24-week-old male Wistar rats. The effects of prednisolone 21-hemisuccinate sodium salt (7 mg/kg s.c. daily) or/and fenoterol hydrobromide (1.4 mg/kg i.p. daily), administered for 4 weeks, on the skeletal system were studied. Bone turnover markers, geometric parameters, mass, mass of bone mineral in the tibia, femur and L-4 vertebra, bone histomorphometric parameters and mechanical properties of tibial metaphysis, femoral diaphysis and femoral neck were determined. Both prednisolone and fenoterol had damaging effects on the skeletal system of mature male rats. However, concurrent administration of fenoterol and prednisolone did not result in the intensification of the deleterious skeletal effect of either drug administered separately.

The bone belongs to the dynamic tissues and its structure in domestic cows is still not completely understood in correlation to the impact of different food components. The aim of our work was a histomorphometrical and immunohistochemical research on bone morphology and factors influencing it in healthy dairy cows fed with self-produced grain and with rapeseed cakes. The bone of self-produced grain-fed cows demonstrated statistically significant difference in the number of osteocytes from the bone of rapeseed cakes-fed cows. The rapeseed cakes-fed cows didn't show any bone cell positive for BMP2/4, while FGFR1 increased significantly in their supportive tissues. The number of bFGF- and apoptosis-containing structures varied in cows of both groups. MMP2 expression showed statistically significant difference between both animals' groups with domination in bone of cows fed with self-produced grain. Defensin-, osteopontin- and osteocalcin-contain- ing cells showed tendency to increase in bone of cows on rapeseed cakes diet. Conclusions. The rapeseed-fed cow's long bones demonstrate significant decrease of osteocytes per mm2 and selective increase of FGFR1, suggesting the (compensatory) growth stimulation in supportive tissue. The statistically significant selective absence of MMP2 with a slight tendency of increase in osteopontin and osteocalcin in rapeseed-fed cow's long bones indicates the persistence of seemingly still compensated qualitative changes in bone (beginning of disturbances in mineralization, metabolism etc.) proved also by a slight increase of the bone antimicrobial peptide.
