ABSTRACT

SUMMARY:

Acrylamide is a toxic chemical substance with wide implementation in chemical industry. In 2002 the presence of acrylamide was discovered in foods rich in starch which are prepared at high temperatures. The aim of this study was to investigate the histopathological changes in the gastric tissue in Wistar rats induced with injection of oral acrylamide. The research was carried out 6 groups of 5 animals (Wistar rats), two control groups and four experimental groups. Histological changes in the stomach tissue of Wistar rats are seen as a direct slight damage of the surface epithelium, accompanynig inflammatory reaction and renewal of the epithelium. Examined inflammatory and degenerative parameters show a positive correlation with respect to dose and time of exposition to acrylamide. Knowing the mechanism of action of these toxic substances, allows to apply adequate prevention in nutrition and make an appropriate choice of therapeutic methods.
RESUMEN
RESUMEN La acrilamida es una sustancia química tóxica con amplia aplicación en la industria química. En el año 2002 se determinó la presencia de acrilamida en alimentos ricos en almidón preparados a altas temperaturas. El objetivo de este estudio fue investigar los cambios histopatológicos en el tejido gástrico en ratas Wistar inducidos con inyección de acrilamida oral. La investigación se llevó a cabo en 6 grupos de 5 animales, dos grupos control y cuatro grupos experimentales. Los cambios histológicos en el tejido del estómago de las ratas Wistar se ven como un ligero daño directo del epitelio superficial, que acompaña a la reacción inflamatoria y la renovación del epitelio. Los parámetros inflamatorios y degenerativos examinados muestran una correlación positiva con respecto a la dosis y el tiempo de exposición a la acrilamida. El conocimiento del mecanismo de acción de estas sustancias tóxicas permite aplicar una prevención adecuada en nutrición y hacer una elección oportuna de los métodos terapéuticos.
