title: Contribution to histochemical distribution of non-specific cholinesterase activity in sensory ganglia of some mammals.
abstract: The activity of non-specific cholinesterase was demonstrated histochemically in satellite cells of the spinal ganglia from adult rat, cat, rabbit and baboon. The spinal ganglia of newborn rats displayed distinct intraneuronal reactivity for non-specific cholinesterase while a low reactivity was observed in satellite cells. The spinal and trigeminal ganglia of adult mice contained satellite cells with non-specific cholinesterase reactivity only sporadically. Most of reaction product for non-specific cholinesterase activity (from low to high intensity) was found in perikarya of the neurons. Spinal and trigeminal ganglia of the same mice embryo exhibited diffuse staining for non-specific cholinesterase activity remaining in the spinal ganglia of newborn mice. The trigeminal ganglia of newborn mice exhibited, however, more differentiated pattern of the positive reaction for non-specific cholinesterase like adult animals. The pattern of histochemical distribution of non-specific cholinesterase activity in trigeminal and spinal ganglia from mice of various ages corresponds with morphological differentiation and maturation undergoing in a rostrocaudal wave. Intraneuronal presence of non-specific cholinesterase activity in sensory ganglia during development and in adult animals gives a new possibilities for explanation of the functional involvement of this enzyme in the nervous system.
