摘要：

Thermal imaging and laser Doppler flowmetry were used to study vascular response-associated infrared (IR) radiation effects in healthy volunteers subjected to regular unilateral arteriovenous occlusion of one of the fingers (four times a day for seven months with a gradual increase in exposure from 10 to 30 min). After repeated unilateral exposures, consistent changes in the temperature and thermoregulation modes were observed on the corresponding skin areas of both hands. There was a high positive correlation between the dynamics of IR emission from the experimental and control skin areas in the recovery phase after clamping, suggesting that the systemic vascular response was involved. The possible mechanisms of postocclusive changes in the skin of the distal phalanges are discussed. Our data suggest that multiple regular unilateral arteriovenous occlusions enhance the intradermal blood flow and can be used to prevent peripheral microcirculation disorders in various pathological conditions. © 2015, Pleiades Publishing, Inc.
