Resumen
Introduccion

Los antiinflamatorios no esteroides (AINE) retrasan la cicatrizacion de la ulcera peptica por mecanismos en parte desconocidos. Los factores de crecimiento cumplen un papel importante en el proceso de cicatrizacion.

Objetivo

Evaluar si la administracion exogena del factor de crecimiento derivado de plaquetas (PDGF) y el factor de crecimiento epidermico (EGF) revierten el efecto de la indometacina en la ulcera duodenal experimental en ratas, y definir los mecanismos potenciales involucrados en este proceso.

Método

Se indujo ulcera duodenal con acido acetico en ratas Wistar macho y se trato con indometacina (2 mg/kg/ dia), PDGF-BB (30 ng/100 g/dia), EGF (50 µ/kg/dia) o famotidina (control positivo) (1 mg/kg/dia) o las posibles combinaciones. Se analizaron el area macroscopica, la reduccion del diametro microscopico, la proliferacion en el tejido epitelial y de granulacion, la secrecion de colageno por este tejido y la secrecion acida gastrica.

Resultados

La indometacina retraso la cicatrizacion de la ulcera duodenal disminuyendo la proliferacion celular y origino una inhibicion de la secrecion de colageno. PDGF y EGF aceleraron la cicatrizacion y revirtieron el efecto de la indometacina en la cicatrizacion. Los mecanismos involucrados se asociaron a un aumento en la proliferacion y secrecion de colageno sin afectar a la secrecion acida gastrica. La famotidina tambien acelero la cicatrizacion y revirtio el efecto de la indometacina asociado a la profunda inhibicion de la secrecion acida gastrica y al aumento de la secrecion de colageno por parte del tejido de granulacion.

Conclusiones

La administracion exogena de PDGF y EGF acelera y revierte el efecto deletereo de la administracion de indometacina en un modelo experimental de ulcera duodenal.

Background

Nonsteroidal anti-inflammatory drugs (NSAIDs) delay peptic ulcer healing through mechanisms that are still not entirely understood. Growth factors play a significant role in healing.

Aim

To evaluate whether exogenous administration of platelet-derived growth factor (PDGF) reverses the effect of indomethacin in experimental duodenal ulcers in rats and to define the potential mechanisms involved in this process.

Method

Duodenal ulcer was induced in male Wistar rats with acetic acid. The rats were then administered indomethacin (2 mg/kg/day), PDGF-BB (30 ng/100 g/day), epidermal growth factor (EGF) (50 ì/kg/day) or famotidine (positive control) or the possible combinations of these. Macroscopic area, reduction in microscopic diameter, epithelial and granulation tissue proliferation, collagen secretion by granulation tissue, and gastric acid secretion were analyzed.

Results

Indomethacin delayed duodenal ulcer healing by decreasing cellular proliferation and inhibiting collagen secretion. PDGF and EGF accelerated healing and reversed the effects of indomethacin. The mechanisms involved were associated with an increase in collagen proliferation and secretion without affecting gastric acid secretion. Famotidine also accelerated healing and reversed the effect of indomethacin, and these effects were associated with a marked inhibition of gastric acid secretion and increase in collagen secretion by granulation tissue.

Conclusions

Exogenous administration of PDGF and EGF accelerated healing and reversed the harmful effects of indomethacin in an experimental model of duodenal ulcer.
