[Simple method of demonstrating adrenergic nerve structures in human and animal tissues using a glyoxylic acid solution].

A method for obtaining injection replications of microvessels for scanning electron microscopy using nonsaturated polyether resin PH-8 is described. Possible applications of the method in question to study microcirculatory bed are discussed. With resine PH-8 it is possible to obtain complete and detailed replications which give information on three-dimensional organization both of the microcirculatory bed and of the vascular microrelief peculiarities.
