["Circular bands" on the casts of the microcirculatory bed of the human heart in ontogenesis (data from scanning electron microscopy of corrosive casts)]. / O "tsirkuliarnykh poloskakh" na slepkakh sosudov gemomikrotsirkuliarnogo rusla serdtsa cheloveka v ontogeneze (po dannym skaniruiushchei élektronnoi mikroskopii korrozionnykh preparatov).

By means of scanning electron microscopy of corrosive casts, applied to the human cardiac hemomicrocirculatory bed vessels, beginning from 6-9-month-old fetuses up to persons of elderly and old age, peculiarities in form, dimensions and distribution have been revealed in the wall of the arterial part of the vessels of the hemomicrocirculatory bed of so called circular strips. They are inevitable structural components in the wall of the vessels mentioned and correspond to smooth myocytes, shifted at methylmetacrilate injection.

By means of Gerota mass and silver nitrate solution, injected into the myocardium and its vessels, as well as using the scanning electron microscopy technique for corrosive casts, links of the human myocardial lymphomicrocirculatory bed have been studied, beginning from 6-9-month-old fetuses up to elderly and old age persons. Changes in form, dimensions and amount per a volumetric unit have been stated in myocardial capillaries and postcapillaries. These signs demonstrate that the myocardial lymphatic system has different importance for each stage of individual development of the human heart.

Hearts of 220 human corpses, who had not any cardiovascular system disease during their life, have been distributed into age groups, beginning from fetuses up to old age. By means of injection, silver nitrate impregnation and scanning electron microscopy methods, applied to corrosive preparations, morphological mechanisms of the blood stream regulation in the hemomicrocirculatory bed of the human heart have been revealed in ontogenesis. The first group of the regulation mechanisms includes proper mechanisms inherent in the links of the microbed: spatial orientation of microvessels, precapillary sphincters, anastomoses between these vessels, sequence in arrangement of the endothelial cell nuclei, length, diameter and number of links in the microcirculatory bed. The second group embraces those mechanisms, that depend on structure of the myocardial wall, influencing the microcirculatory bed.

[Vascular anastomoses of the blood microcirculatory bed of the human heart]. / Anastomozy sosudov gemomikrotsirkuliatornogo rusla serdtsa cheloveka.

Using a complex of morphological techniques both injective and non-injective, scanning electron microscopy including, the hemomicrocirculatory bed and vascular anastomoses have been studied in various parts of the human heart. In most cases anastomoses between the microcirculatory links are realized at the level of capillaries, precapillary arterioles and postcapillary venules. Venulo-venular anastomoses are demonstrated in the myocardium. Existence of terminal arterioles is discussed.

[The microcirculatory bed of the human heart]. / Mikrotsirkuliatornoe ruslo serdtsa cheloveka.

Using a complex approach in studying microcirculatory bed of the human heart, possibilities of scanning electron microscopy of corrosive preparations, those of silver nitrate impregnation after V. V. Kuprianov are demonstrated. The silver nitrate impregnation makes it possible to study the wall structure of the microcirculatory pathways, to analyse arrangement of nuclei in the endothelial and muscle cells of the microcirculatory links, to reveal together with the vessels the surrounding tissues. Scanograms of the corrosive preparations of the arterioles demonstrate "circulatory strips", that are absent in the venular part. The relief of the luminal casts of the microcirculatory bed vessels in the human heart is presented as impresses of nuclei of the endothelial and smooth muscle cells. Peculiarities in form and distribution of these nuclei in various links of the microbed are demonstrated.

[Variability in the diameter of the capillaries of the human heart during development]. / Variabel'nost' diametra kapilliarov serdtsa cheloveka v ontogeneze.

Seventy-eight hearts from persons, who had not suffered any cardiovascular disorders during their life time, have been studied. Microcirculatory bed vessels are revealed by impregnation with silver nitrate after V. V. Kuprianov. The values of the capillary diameters obtained are mathematically treated using T. H. Bayes formula. Periods of individual development of the heart are defined when a high functional activity of the capillary bed of the auricles and ventricles is noted. Evidently, this is one of the factors contributing to development of the cardiac ischemic disease.

[Organ and tissue-specific properties of the microcirculatory bed of the heart]. / Organo- i tkanespetsificheskie svoistva mikrotsirkuliatornogo rusla serdtsa.

The auricular and ventricular microcirculatory bed has been studied in persons of mature age, not suffering from any cardio-vascular diseases during their life. As a whole, 48 objects have been studied. The microcirculatory bed has been revealed in sections of the cardiac wall 70-100 mcm thick using silver nitrate impregnation after V. V. Kuprianov. Organ- and tissue-specific properties of the vascular microcirculatory bed are revealed in interrelations of the vessels and the structural elements of the cardiac wall (myocardium, and connective tissue structures), in position of nuclei of the endothelial cells of the capillary wall and in places of the capillary branchings. Principle differences in structure of the auricular and ventricular microcirculatory bed are demonstrated. The notion the organ- and tissue-specific properties of the microcirculatory bed vessels is discussed.

[Quantitative analysis of the structural organization of the human ventricular myocardium]. / Kolichestvennyi analiz strukturnoi organizatsii miokarda zheludochkov cheloveka.

A special technique was worked out in order to study structural organization of the ventricular myocardium (90 human hearts without pathological signs) at macromicroscopical level. It is convenient to estimate spatial orientation of the cardiac contractile elements by the direction of fibrillar fasiculi at definite points. Quantitative characteristics on orientation of myocardial fibrillar fasciculi were obtained according to depth and extension of the cardiac wall in reference to the three-dimentional system of coordinates. Mathematical description of the structural organization of the ventricular myocardium was presented, the cardiac wall was considered as a thick envelope of a complex form. The structural organization was described by means of single vectors, tangents to the fibrillar fasiculi of the myocardium at the points of measurements.
