[Histomorphology of the microcirculation of the skin in physiological and pathological processes]

On the base of skin histomorphological investigations of 985 deceased with different diseases age morphological pecularities in microcirculation were concluded to exist as well as changes depending on the duration and character of the pathological process. The involvement of a great number of vessels is an index for increased functional microcirculation requirements. The microcirculation character cannot be defined only by the morphological pecularities of single capillaries, by quantitative and qualitative changes in them. The capillary changes relfect only part of the microcirculation changes. All microcirculation peculiarities cannot be deciphered by the histomorphological method of the investigation but that method supplies valuable data that cannot be obtained by the other investigation methods. Three stages of changes in microcirculation are specified, being morphologically characterized. The changes in the microcirculation of the nail mantle skin are non-specific, functional, organic, reversible, non-reversible and usually compensated.
