    Abstract:
    In four dogs (2 males and 2 females from one litter) with established gastric cannula gastric secretion was studied in control experiments and in induced experimental neurosis. Gastric secretion was stimulated by insulin. We monitored in individual 15 min. portions the amount of gastric juice, total HCl output, output of acid gastric proteinases, mucoproteins and some ions. The gastric juice was dialyzed and freeze dried. 50 mg of the lyophilisate was separated on Sephadex G 100. Macromolecular substances were fractionated into glycoproteins (peak I), acid gastric proteinases (peak II) and glycopeptides and polypeptides (peak III). The ratio of these individual macromolecular substances remainded constant in the same dog in all control experiments. However, there were significant differences between individual animals. Induction of experimental neurosis (by collision of the alimentary and avoidance reflex) gave rise to changes not only in the output of HCl and gastric proteinases, but also in the ratio of macromolecular substances. In the series of observed parameters these changes were of a different nature in males and females.
