[Cystathionine beta-synthase in the structural elements of the human brain and spinal cord].

Investigated by immunohistochemistry the presence and distribution of CBS in the nuclei of the spinal cord and brainstem in 8 mens of 18-44 years old, died from mechanical injury is not related to the central nervous system damage. Established that the CBS-neurons are revealed in all parts of stem and spinal cord, but their content in the studied cores, ranging from 0.9 to 17 %. Observed a definite relationship between the activity of CBS and the quantity of neurons. Large cells of motor nuclei often have a high and very high intensity of the reaction. In the sensory nuclei of a high proportion of small neurons with low activity of the enzyme.
