| Los tumores estromales gastrointestinales (GISTs) comprenden a tumores de origen mesenquimal que antes eran clasificados como "tumores del músculo liso", no obstante los avances en el campo de la microscopía electrónica e inmunohistoquímica han permitido su diferenciación. Derivan de las células intersticiales de Cajal, representan el 1-2% de todas las neoplasias del tubo digestivo y son más frecuentes en personas mayores de 40 años, con igual incidencia en ambos sexos. Se estudiaron 30 casos de GISTs en un análisis prospectivo y retrospectivo, en el período comprendido entre los años 1987 y 2007. Para el material retrospectivo se estudiaron bloques de tejidos en parafina. El material se fijó en formaldehído al 10% y se incluyó en parafina, realizando... |

| The effect of bisacodyl on the treatment of rats with slow transit constipation (STC) was studied. Forty-five female Wister rats were divided into control group, STC group, and STC bisacodyl group. The immunohistochemical method was used to determine interstitial cells of Cajal (ICC) and the expression of c-Kit protein. Body mass and the number of defecations were significantly decreased in the STC group compared with the control group on the 100th day after diphenoxylate administration, while dry weight of feces was significantly increased and the intestinal transit time was prolonged. There were significant differences in the number of defecations, dry weight of feces, and intestinal transit time among the three groups. The number of defecations was... |
