[Change of blood volume in the kidney cortical and medulla vessels in aging process].
We studied the volumes of arterial and venous vessels (cortical and medulla) of a kidney, excepting microcirculation system. The research covered 76 corrosion preparations of kidneys of people, aged from 21 till 85 years, died from diseases which could not affect on morfofunctional condition of kidneys and their vascular system. We have found out that morphological changes in kidneys at aging are characterised, basically, by progressing nephrosclerosis. The major factor provoking development of sclerous changes in a kidney is the age changes of kidney arterial vessels. It is proved that structural changes in venous and arterial vessels in involution are characterised by gradual decrease of volume of cortical substances vessels, where the considerable part of blood proceeds.
