title: [State of Dogiel type II neurons in the wall of the cat small intestine following a single exposure to gravitational stress].
abstract: Under study was the nervous apparatus of the small intestine in 22 cats subjected to a single gravitation stress by rotation in a centrifuge of 1,5 m radius. The stress was equal to 10 units, duration from 2,5 to 3,5 min., and was of head-pelvis direction. The material was treated after Nissl and Gomori in Chilingarian's modification. Within 1-3 days after exposure to gravitation stresses in the Auerbach plexus there appeared changes in the shape of the body of the type II Dogiel cells, such as pericellular oedema, vacuoles in the cytoplasm, chromatolysis and varicous thickenings of nerve fibres. Terminal structures of the dendrites of the type II Dogiel cells are thickened. The changes are most pronounced within the 4th-7th days after exposure to gravitation and are observed as late as the 14th day, being sharply diminished by the 30th day.
