Paper Abstract

The interest to the non-invasive study of capillary blood flow in cardiological and diabetes patients is raised mainly by the explicit microcirculation disorder in such pathological patients. The interest to quantitative microcirculation parameters in the recent years has promoted the development of new technical facilities. In 1997, the Centre for Analysis of Substances in collaboration with a design team of the Space Device-Making Institute developed the computerized capillaroscope. This device consists of a high-resolution microscope with a magnification of up to 1000 and a color CCD camera that sends the image to a PC- based video processing station. An important merit of the instrument is the possibility of conducting non-invasive investigations, i.e. without damage to the skin or vessels and not causing any pain or unpleasant sensations. The sophisticated software provides for the possibility of accurately measuring capillary blood velocity as well as the size of the perivascular zone.
