ABSTRACT
Dithiocarbamate propinebs are organometal fungicides that are widely used for the control of diseases in plants. In this study, pregnant female rats received 400 ppm propineb concentrations in 5 ml distilled water for 16 days of gestation, and then infant rats were obtained by cesarean section. In the histological analysis on the frontal sections, the use of propineb was found effective on odontoblast cell hyperplasia, cell infiltration in the dental papilla, and degeneration in the mesenchymal cells of the outer enamel. The expression of MMP-2 (Matrix Metalloproteinase-2) and VEGF (Endothelial cell growth factor) in the connective tissue was evaluated by immunohistochemistry. The drinking water given to the mothers in propineb tooth bud, enamel and dentin, resulted in morphological changes suggestive of a delay in formation, which cross the placental barrier and possibly affect the tooth development.
RESUMEN
Los ditiocarbamatos (Propineb) son fungicidas organometálicos que son ampliamente utilizados para el control de enfermedades en las plantas. En este estudio, ratas hembras preñadas recibieron concentraciones de 4000 ppm de propineb en 5 ml de agua destilada durante 16 días de su gestación. Luego, las crías de las ratas fueron obtenidas mediante cesárea para su estudio estudio histológico. En el análisis histológico de las secciones frontales, el uso de propineb fue positivo para la hiperplasia de las células odontoblástica, infiltración de células en la papila dental, y la degeneración en las células mesenquimales del epitelio externo del esmalte. La expresión de MMP-2 (metaloproteinasa de la matriz 2) y VEGF (factor de crecimiento de células endoteliales) en el tejido conectivo se evaluó por inmunohistoquímica. El agua potable con propineb dada a las madres actuó sobre el brote dentario, esmalte y dentina; se tradujo en cambios morfológicos indicativos de un retraso en la formación. Por tanto, el propineb atraviesa la barrera placentaria y posiblemente afecten el desarrollo de los dientes.
