Aim: The goal was to examine the effects of direct exposure of stomach tissue to  acrylamide. Introduction: Acrylamide is a toxic chemical substance discovered in foods rich in starch, prepared at high temperatures. Material and Methods: The research was carried out 6 groups of 5 experimental animals (Wistar rats). Two control groups orally implicated distilled water. Two experimental groups orally administrated PLENARNE USMENE PREZENTACIJE 21 MATERIA MEDICA • Vol. 34 • Issue 1, suplement 1 • april 2018. acrylamide in a daily dose of 25 mg/kg, and two dose of 50 mg/kg. Three groups were sacrificed after 24h and three after 72h, On histological gastric tissue material is applied qualitative and semi-quantitative histological analysis, stereological measurements of individual compartments of the stomach wall, linear measuring the number of mast cells in the mucosa and submucosa. Results: Slight damage of the surface epithelium, accompanying mild inflammatory reaction and degranulation of mast cells are results of histological damages in the stomach tissue. Reconstruction of the epithelium follows directly toxic effect on epithelium, and it is confirmed by the presence of immature form of mucoproductive cells. Examined inflammatory and degenerative parameters show a positive correlation with respect to dose and/or a time of exposition to acrylamide. Conclusion: Understanding the mechanism of action of acrylamide allows to apply adequate prevention and make an appropriate choice of therapeutic methods.
