Objective: to determine the morphometrical variability of dental alveoli bilaterally, depending on their position in the alveolar part of the mandible. Material and Methods. The object of the study is to certify 70 cranions with mandibles of middle-aged adults (21-60 years) and 30 isolated mandibles without gender-and age-related characteristics. The objects of the study were taken from scientific cranial fundamental museum collection of the Department of Human Anatomy. For the scientific research Craniometry method was used according to generally accepted craniology process parameters. Dental alveoli on both sides of the mandible were studied. Results. It was established that longitudinal diameter prevails at tooth alveoli of a canine, the first and second premolars, cross diameter on the same side of a jaw at the left — at alveoli of a medial incisor and the first premolar in comparison with its right side. At dental alveoli the left-sided depth is larger of the first molar, of the second molar — the right-sided is larger. Longitudinally cross diameter in the direction from alveoli of front teeth to back ones increases at each subsequent alveolus, since the minimum size at incisors and reaching the maximum size at alveoli of the first and second molars. The largest depth of tooth alveoli is determined at a canine, the first and second premolars. Conclusion. Results of the research of bilateral and individual variability of parameters of tooth cells may be used in practical stomatology.

The aim of the study is to determine the influence of a partial temporary ischemia and reperfusion on the development of pancreatitis in laboratory rats. Material and Methods. The experiments were performed on 73 white rats. Occluded blood vessels and blood flow were recorded by digital biomicroscopy and laser speckle contrast imaging. Statistical data processing was carried out the program Statistica for Windows 6.0 using the Student's criterion. Results. Laser speckle imaging and digital microscopes provide the monitoring of blood flow in the vessels of the pancreas. After a five-minute partial ischemia reactive hyperemia occurs, changes are invertible. After a twenty-minute partial ischemic reactive hyperemia does not occur, without developing pancreatitis necrosis. Pancreas of alcoholized rats has been found out to be more sensitive to ischemia. Conclusion. The method of laser speckle imaging and intravital microscopy after digital five- and twenty-minute partial ischemia of the pancreas revealed phase opposite directed changes in its tissue perfusion and varying severity of postischemic pancreatitis.

Problems of social conditionality of population health are a traditional topic to discuss both in medical and social sciences. Availability of health care is considered from the perspective of social factors of macro level, representing the widest context of social factors to health risk. In Russia, the increasing availability of health care for the population is considered as a priority of social policy. The authors of the review publications consider the trends of accessibility of medical care to the population of contemporary Russia. It is noted in the article that currently the availability and quality of medical care, pretentiousness of state assurances for free medical care, and their imbalance with available financial resources are considered as one of the major Russian health care problems.
