ABSTRACT
In this study we examined the effects histopathologic and immunohistochemical of xylene inhalation in rats by using light microscopy. Adult wistar albino rats were used in this study. Eight rats were in control group and 8 rats were in the experimental group. The experimental group was exposed to 300 ppm formaldehyde 3­5 min/day, 5 days/week for 8 weeks. The lining epithelium of respiratory mucosa showed a loss of ciliated cells with metaplasia of goblet cells, hyperplasia of squamous cells and edema, inflamation in sub epithelial area). In the group treated xylene. Disruption of cell-cell contact was observed. Weak expression of E-cadherin was observed between cells. The vascular endothelium of capillaries and venoles showed intense immunostaining for VEGF.
RESUMEN
Se examinó el efecto histopatológico e inmunohistoquímico de la inhalación de xileno en ratas mediante el uso de microscopía de luz. Se utilizaron ratas albinas Wistar adultas. Ocho ratas formaron parte del grupo control y 8 del grupo experimental. El grupo experimental fue expuesto a 300 ppm de formaldehído, 3­5 min/día, 5 días/semana, durante 8 semanas. El epitelio de revestimiento de la mucosa respiratoria mostró una pérdida de células ciliadas con metaplasia de células caliciformes, hiperplasia de células escamosas y edema, con inflamación en la zona subepitelial. En el grupo tratado con xileno se observó una interrupción del contacto célula-célula. Se observó una débil expresión de E-cadherina entre las células. El endotelio vascular de los capilares y vénulas mostraron intensa inmunotinción de VEGF.
