Fig. 2From: Characterization of skin function associated with obesity and specific correlation to local/systemic parameters in American womenAnalyses of blood flow and hemoglobin dynamics. Real-time blood flow images were obtained by a laser speckle blood flow system and analyzed to characterize perfusion in the skin. Average and standard deviation (SD) of blood flow in the region of interest (ROI) were presented (a and b, respectively). Typical blood flow images were shown (c). Hemoglobin dynamics in the subcutaneous tissue was evaluated by a tissue-blood oxygenation monitor to analyze Oxy-Hb (d), Deoxy-Hb (e) and Total-Hb (f) **: p < 0.01, compared between mean values in two groupsBack to article page
