[Aging features in functioning of skin microvascular bed in humans].
The state of skin microcirculation system has been studied in healthy volunteers aged from 20 to 77, using laser Doppler flowmetry. To reveal the reaction of microvascular bed in response to short-term ischemia, occlusive test has been carried out. During experiment the age-induced reduction of microcirculation index has been observed at rest. In response to stopping occlusion the 3.5--4-aliquot increase of microcirculation index has been revealed during reactive post-occlusive hyperemia in all age groups. The data obtained suggest maintenance of high reserve resources of skin microcirculation in ageing in response to ischemia.
