Assessment of Human Skin Microcirculation and Its Endothelial Function Using Laser Doppler Flowmetry
Human skin is the largest organ of the body: it accounts for approximately 5% of the total body weight, extends over about 1.8 m2 and has an average thickness of 1-2 mm. Besides providing the mechanical barrier to protect the surface of the body and to prevent water loss it has other important functions. It is engaged in sensory perception and vitamin D metabolism, in inflammation, hemostasis a...
متن کاملMicrocirculation assessment using an individualized model for diffuse reflectance spectroscopy and conventional laser Doppler flowmetry.
Microvascular assessment would benefit from co-registration of blood flow and hemoglobin oxygenation dynamics during stimulus response tests. We used a fiber-optic probe for simultaneous recording of white light diffuse reflectance (DRS; 475-850 nm) and laser Doppler flowmetry (LDF; 780 nm) spectra at two source-detector distances (0.4 and 1.2 mm). An inverse Monte Carlo algorithm, based on a m...
متن کاملAssessment of skin microcirculation by laser Doppler flowmetry in systemic sclerosis patients
INTRODUCTION First lesions to occur in the course of systemic sclerosis (SSc) involve microcirculation. AIM The study involved assessment of the suitability of laser Doppler flowmetry (LDF) in examination of the performance of skin microcirculation in the distal portion of the upper extremity in SSc patients. MATERIAL AND METHODS Overall the study involved 27 patients with systemic sclerosi...
متن کاملQuantitative Laser Doppler Flowmetry
vii-Abstract Laser Doppler flowmetry (LDF) is virtually the only non-invasive technique, except for other laser speckle based techniques, that enables estimation of the microcirculatory blood flow. The technique was introduced into the field of biomedical engineering in the 1970s, and a rapid evolvement followed during the 1980s with fiber based systems and improved signal analysis. The first i...
متن کاملHe-Ne laser effects on blood microcirculation during wound healing: a method of in vivo study through laser Doppler flowmetry.
BACKGROUND AND OBJECTIVES Low-intensity laser therapy (LILT) is widely used for wound healing promotion and its mechanism of action may be due to an enhancement of blood supply. The aim of this study was to evaluate blood flow alterations in a wound healing model, using laser Doppler flowmetry (LDF) associated with a normalized perfusion parameter. STUDY DESIGN/MATERIALS AND METHODS An injury...
