[Use of the Gallyas impregnation method in the study of angioarchitecture in cerebrospinal gliomas in humans].

The Gallyas' method based on impregnation of endothelial basal lamina and reticulin fibres, allowing to reveal the microcirculatory bed, was used to demonstrate the angioarchitecture of brain and spinal cord tumours. This technique, for the first time, enables a more complex view on tumours tissue microvascular architecture than previously. Using of thick paraffin sections enables to incorporate this method into the set of routine diagnostic histology.
