| description | Objective: to study the structural transformations of the architectonics of intra-organ renal arterial vessels in the age aspect.Materials and methods: 150 kidneys of people of diff erent age who died from the reasons which are not connected with diseases of cardiovascular and urinary systems are investigated. The studies were carried out using a set of methods: angiographic, macromicroscopic and morphometry.Results: with increasing age, a decrease in the number of vascular glomeruli in the kidney, the proportion of glomerular mass in the cortical substance of the kidney was found. In old age and in centenarians, a rare capillary network in the cortical substance of the kidney, tortuosity, narrowing and expansion of direct arterioles and capillaries in the cerebral substance was revealed. In old age and in centenarians, compared with adolescence, the relative content of arterial vessels in the cortical substance decreases by 6 times, in the juxtamedullary zone — by 4 and in the cortical substance — by 2 times.Conclusions: the large diameters of the juxtamedullary glomeruli and a large index of the relative content of arterial vessels in the juxtamedullary zone create prerequisites for possible juxtamedullary shunting with urgent adaptation in the norm. The decrease in these indicators in old age, the elderly and centenarians, obviously, explains the age-related decline in the adaptive capacity of the arterial bed of the kidneys. With increasing age, the range of adaptive capabilities of the renal vascular bed of aging people decreases compared to those of mature age. |
