Summary:

Objective was to study the characteristics of the indicators of the width of the dental arches of the lower jaw at the dolichomorphic form of the skull. Material and Methods. The morphometric parameters of the width of dental arches of the lower jaw have been studied. The work was performed on 28 preparations of skulls of people of both sexes of mature age with physiological occlusion of teeth and dolichomorphic form of the skull. The width of the dental arch was measured between canines, premolars and molars. Results. The maximum value of the width of the dental arch in both men and women was observed in the region of the second molars from the vestibular side. The minimum value of the investigated parameter was revealed in the region of canines on the palatal side. The indicator of the width of both the vestibular and lingual dental arches increased from the level of the canines to the molar level. Conclusion. A significant increase in the parameters of the width of the vestibular dental arch of the lower jaw in men over similar indicators in women was revealed only at the level of canines and first molars, and the parameters of the lingual dental arch only at the level of the second premolars.

Morphometric parameters of air in lungs of laboratory rats on physical exercise.

Summary:

Aim: to determine the morphological and functional relationships between the morphometric parameters of lung airness tissue specimens of laboratory rats and indicators of physical endurance while swimming with weights and running on a treadmill. Material and methods. The physical endurance of laboratory rats evaluated in tests of swimming with weights and running on a treadmill using computer video markerless tracking. After strenuous exercise prepared histologic lung stained with hematoxylin and eosin. In morphometric study there were determined areal parameters of lung airness and pulmonary distelectasis. Results. When comparing the results of studies of physical endurance to the morphometric data of lung airness and pulmonary distelectasis identified the parameters of the same type of regression. Between changes in the morphological and physiological characteristics was a strong and average power correlation. The highest coefficient of correlation was established between the indicators of physical endurance and the parameter characterizing the degree of pulmonary distelectasis. Conclusion. Indicators of physical performance were the best in the big lung airness. At the same time, to a lesser extent than in the lung were presented wears off portions of the alveoli, the longer the biological objects to perform physical work. Fitted regression dependence characterizing the effect on physical endurance performance airiness of the lungs and spread them distelectasis.

Organization: Penza State University
Summary:

Objective: to identify the microscopic features of the structure of the thyroid gland in different forms of its pathology. Materials and Methods. The study is based on the thyroid glands of 199 patients of both sexes aged 21 to 74 years. Results. At the micro-macrofollicular nontoxic goiter was found flattened thyroid epithelium with flattened normochromic nucleus, the small size of cells and nuclei, low nuclear-cytoplasmic index, intrafollicular moderate epithelial proliferation, homogeneous colloid and moderate diffuse lymphoid infiltration. At the micro-macrofollicular toxic goiter detected cubic epithelium with rounded normochromic kernel, smallest size of cells and nuclei, nuclear-cytoplasmic minimum index intrafollicular focal proliferation of the epithelium, colloid mesh boundary with severe vacuolization, focal lymphoid infiltration and hemorrhage. When diffuse toxic goiter detected cubic form cells of medium size with a fairly high nuclear-cytoplasmic index, rounded normochromic kernel, rare intrafollicular epithelial proliferation, homogeneous colloid with an edge vacuolization. With the prevalence of autoimmune thyroiditis was observed flattened epithelium with rounded normochromic nucleus, the small size of cells and nuclei, found the average nuclear-cytoplasmic index, homogeneous colloid and extensive lymphoid infiltration with light propagation centers. Adenoma of the thyroid gland epithelium was found with a cubic cell shape, round hyperchromatic nucleus, the large size of cells and nuclei, high nuclear-cytoplasmic index intrafollicular diffuse proliferation of epithelial and dense colloid. When thyroid cancer found the prevalence of papillary structures with short broad papillae formed polymorphic cells with round hyperchromatic nucleus, there is the largest size of cells and nuclei, nuclear-cytoplasmic maximum index expressed intrafollicular diffuse proliferation of the epithelium. Conclusions. Each form of thyroid disease, along with well-known typical microscopic manifestations is a characteristic regional feature of the microstructure.

Heading: Macro- and Micromorphology Article type: Original article
Authors: Kalmin O.V., Kalmin О.О..
Organization: Penza State University
Summary:

Purpose: the complete analysis of the morphological parameters of the thyroid gland in various forms of thyroid pathology by methods of mathematical modeling. Material and Methods. Histologically examined samples of operating thyroid glands of 199 patients of both sexes aged 21 to 74 years, were treated surgically. Experimental data were studied by factorial and discriminant analysis. Results. When the factor analysis of 60 experimental parameters were identified 14 major factors that indicate 14 main trends in the dynamics of the structure of the thyroid gland due to an increase in severity of pathological processes. Discriminant analysis showed that the study of quantitative structure of the thyroid gland there may be cases of erroneous inclusion in the theoretical option groups, however, the study of the entire set of indicators observed a 100% correct distribution of cases by groups of pathology. Conclusion. As a result, the factor of the original system of 60 morphological parameters of thyroid pathology in various forms has been minimized to 14 new uncorrelated parameters (main factors), reflecting changes in the morphology of the basic laws of the pathology of the gland. As a result of the discriminant analysis of morphological parameters of the thyroid gland in different types of its pathology the importance of semi-quantitative parameters of thyroid structure has been revealed.

Organization: Saratov State Medical University, Saratov Scientific Research Institute of Traumatology and Orthopedics
Summary:

CII arch fractures are divided into groups according not to anatomical localization, but to the instability degree resulted from the trauma. Effendi et al classification became greatly widespread. |t is based on the same stability criteria, but it is simpler, intelligible and gives the plan of treatment. All the fractures according to this classification are divided into three types: the first one consists in stable fractures in which even in functional images there is no any rough deformation at the level of CII segment; the second one consists in damages with significant angular (more than 11°) or shift (more than 3,5 mm) deformations, that indirectly indicates damage of soft tissue structures, and first of all diskoligamentous complex. The services of the authors of the present classification are also that they were the first who had defined fracture-dislocation of CII arch, attributed it to the third type. Choice of surgical procedure in unstable CII-III vertebral fractures is ventral spondylosyndesis of CII-III carried out by submaxillary approach after the preliminary closed elimination of deformation of upper cervical part of spine. The differentiated approach to the implant choice with an allowance for morphometric data allows to receive adequate decompression of nervous - vascular structures and reliable stabilization of the damaged segment
