Pilot studies of age-related changes in blood perfusion in two different types of skin

摘要

Laser Doppler owmetry (LDF) was utilized to assess age-related changes in the blood microcirculation at the skinsites with different morphology and regulation. The LDF signals obtained from the glabrous skin of the middlenger pad and nonglabrous skin on the dorsal wrist surface were analyzed. Statistically higher baseline perfusionwas observed in the zone with glabrous skin in the older group of volunteers compared to younger participants.Observed site-specic and age-related dierences in perfusion can be used in the future experimental design forthe studies of the blood microcirculation system in patients with different pathologies.
