[Use of hematoxylin to demonstrate the microcirculatory bed in full-thickness objects and sections of the wall of the gastrointestinal tract].

Slight modifications of the widely applied hematoxylin method of staining make it possible to reveal completely microcirculatory bed in total film preparations and in histological sections of the gastrointestinal wall. Hematoxylin staining of all elements in the vascular wall and the surrounding tissue helps to differentiate definitely every component of the microcirculatory bed and to demonstrate vascular-tissue and vascular-neural interconnections in film preparations and histological sections.
