Abstract

PURPOSE: Various approaches are used to study microcirculation, however, no modality evaluates microcirculation and histomorphology on cellular levels. We hypothesized that reflectance-mode confocal microscopy (RCM) enables simultaneous evaluation in vivo of both microcirculation and histomorphology. PRINCIPALS: The forearm of 20 volunteers was exposed to either local heat stress (HS-group), or to local cold stress (CS-group). RCM was performed prior and after temperature stress to evaluate quantitative blood-cell flow, capillary loop diameter, granular cell size, and basal layer thickness. RESULTS: In the HS-group, we observed significant increase in capillary loop diameter and increased blood-cell flow after heat stress. In the CS-group, significant decreases of capillary loop diameter and in blood-cell flow were determined following cold stress. Granular cell size and basal layer thickness differed insignificantly prior and after local temperature stress. CONCLUSIONS: RCM provides real-time and in vivo high resolution imaging of temperature-dependent changes in the human skin microcirculation and histomorphology on cellular levels.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
