ABSTRACT
The main causes of sudden death of patients suffering myocardial infarction are described. The authors established based on autopsy data the frequency, location, time of development, causes of possible pathogenetic mechanisms and morphology of ruptures of the heart in acute myocardial infarction.

By means of combined morphological methods blood vessels have been studied in 54 uterine tubes of child-birth women. The main pathways for carrying and distribution of blood to corresponding parts of the tube are sector arteries. They are situated in the subserous tela along the anterior and posterior semicircles of the organ. The microcirculatory bed (MCB) of the uterine tube is presented by serous, subserous, muscular and mucosal plexuses. The MCB of the serous tunic is characterized by vascular compositions--modules. Angioarchitectonics of the mucosal tunic is determined with differences in vascularization of complex and simple folds. Organospecific for small arteries and veins of the tubes is presence of vascular mechanisms, regulating the blood stream (intimal cushions, muscular-elastic constrictors, valves and others). Blood capillaries of the mucosal tunic possess a number of ultrastructural peculiarities: thickened peripheral part of endotheliocyte cytoplasm, that contains fenestrae; wide continuous basal membrane with pericytes in its duplication; three types of pericytic-endothelial contacts etc.

By means of light microscopy methods in experiments performed in 60 white rats with modelled venous congestion in the left testis and in 113 men suffering from varicocele of the 2d-3d degree complicated with certain disorders of fertility, the effect of blood correction has been studied in the gonads by switching off the caudal (inferior) epigastric vein. The experimental correction of the blood stream in the testes, according to the data of quantitative estimations, contributes to spermatogenesis. Corresponding positive results, while studying spermograms, are obtained in patients suffering from varicocele complicated with infertility. Application of this operation is expedient when conservative therapy as varicocele is uneffective.
