[Detection of microcirculatory vessels in membranous specimens using Suddan Black B and by means of the Shick reaction].

Methods have been developed using Sudan black B and Shick-test with poststaining with toluidine blue permitting to detect all the basic components of the microcirculatory channel structure in membranous objects (serous membranes). These methods giving good contrast staining of microvessels, blood cells and interstitium provide diverse information on the structure of the microcirculatory bed. The methods proposed are recommended for use in histological laboratories investigating normal and pathological morphology of microcirculation.
