ABSTRACT

Clinical evidence and the use of experimental models in laboratory animals indicate that the intestine is a reservoir of microorganisms that can cause systemic infection in the human. The purpose of this work was to study the possible effect of intestinal obstruction (IO) on the mechanical and chemical barriers that bring protection against microorganisms crossing from the intestinal lumen towards the systemic tissues. We demonstrated that 24 hours after IO, histological and ultrastructural alterations do occur, seriously compromising the structure of the intestinal barrier in 100 per cent of the studies animals. Likewise, it was observed that during the same period, microorganisms translocation from intestine to the peritoneal cavity and liver (100 and 80 per cent respectively) occurred. The lungs were spared. Changes observed in the intestinal epithelium are related to a process similar to that produced by intestinal ischemia: mitochondrial destruction, with subsequent decrease of its capacity to supply eb

ABSTRACT

Las ventajas que ofrece este tratamiento son: 1.Resulta un tratamiento efectivo para el primer eslabón de la cadena productora del Carcinoma del Cuello Uterino como lo es la infección por VPH con sus múltiples cepas oncogénicas que resultó ser sensible al mismo con valor estadísticamente significativo. (P<0.002 y P>0.04). A los 33 meses de observación 5/14 (37.5 por ciento) de todo el grupo ó 5/8 (62.4 por ciento) del grupo que obtuvo respuesta completa están libres de enfermedad con el Cuello Uterino sano. 2.Es no invasivo y es totalmente inocuo para el Cuello Uterino. 3. Es bien tolerado sin efectoS colaterales o secundarios indeseables. 4.Se puede administrar totalmente ambulatorio. 5.Es de costo razonable. 6.Viene a llenar una necesidad terapéutica, asistencial y epidemiológica de importancia para la población
