title: [Regeneration of the gastric mucosa under conditions of massive blood loss].
abstract: The autoradiographic method was used for a comparative study of regeneration of the gastric mucosa after wounding the rat with a preliminary loss of blood and without it. The H3-thymidin label index was determined in the portions of the mucosa of the wound edge and far from it. A histological analysis of healing the wounds failed to reveal any difference in terms of this process in rats with a loss of blood and without it. A momentary massive loss of blood did not influence the strain and intracellular regeneration processes in the healing wound of the stomach: the amount of cells synthesizing DNA at the edges of the gastrotonic wound proved to be the same in experiments both with a loss of blood and without it. The authors believe that it may serve as an indirect evidence of a somewhat exaggerated danger of surgery at the height of gastroduodenal bleeding.
