[Age-related characteristics of the structure of renal arteries].

The investigation has been performed on 337 preparations of human kidneys and on 129 clinical angiograms of kidneys at different age without renal and cardiovascular system pathology. A complex of morphological techniques, mathematical method including, has been used. Peculiarities in architectonics of the intraorganic renal arterial vessels have been described during various age periods of postnatal ontogenesis; essential variations of the renal artery index have been revealed in newborns and adolescents.

[Morphofunctional characteristics of the intrinsic arterial vessels of the kidney in healthy subjects and in various cardiovascular diseases].

The investigation has been performed in 132 kidneys of corpses of persons at various ages, 96 of them died from some cardiovascular diseases and 36--from mechanical asphyxia. Injection, macro-microscopical, histological, biometrical and variational-statistic methods have been used. The total section areas of the arterial vessels is determined, it characterizes the vascular bed capacity of the renal cortical and medullary parts.
