[Acetylcholinesterase in the glial elements of the cat spinal cord].
The Karnovsky-Roots method was used for the light and electron cytochemical detection of acetylcholinesterase distribution in the cat cervical spinal cord. A specific reaction was found not only in nervous elements of the motor nuclei, but also in some astrocytes, satellite glial and Schwann cells. AChE activity was demonstrated in satellite cells accompanying both cholinergic and noncholinergic neurons. An electron microscopic analysis showed electron-dense end-products in the reaction (copper ferrocyanide) in nucleous, on the surfaces of the inner and outer leaves of the nuclear membrane and in its pores, in the perinuclear space and in the pericaria of satellite glial cells on the inner and outer surfaces of the cytoplasmatic membrane of the Schwann cells.
