ABSTRACT

Cadmium, hazardous heavy metal, is recognized to produce severe toxic effects in humans. In this study, intestinal wall surrounding the mesenteric lymph nodes, based on the cadmium to be mainly lymphocytes and plasma cells, granulocytes eozinofil examined effects on the immune system were investigated by histochemical and electron microscope. Electron microscope examination of the cross section of cadmium, mitochondria cristae in the cytoplasm of lymphocytes was observed deterioration in the structure and degenerative changes in dilated endoplasmic reticulum,were seen together with elongation, that a small number of multi-focal granular lymphocytes, but plasma cells and eosinophilic granulocytes of the structures of multi-focal granular structures of various sizes, and their numbers were much higher.


El cadmio, es un peligroso metal pesado, reconocido como causante de graves efectos tóxicos en los humanos. En este estudio, se examinaron los efectos del cadmio sobre el sistema inmune en la pared intestinal que rodea a los nódulos linfáticos mesentéricos, principalmente linfocitos, células plasmáticas y granulocitos eosinófilos, mediante técnicas histoquímicas y microscopía electrónica. En el examen mediante microscopía electrónica de la sección transversal de la pared intestinal sometida al cadmio, se observó un deterioro estructural de las crestas mitocondriales en el citoplasma de los linfocitos y cambios degenerativos en el retículo endoplásmico, además fueron vistos con un pequeño número de linfocitos granulares, células plasmáticas y granulocitos eosinófilos con estructuras granulares multifocales de diversos tamaños y más altos.
