RESUMO

To investigate ursodeoxycholic acid (Urso) action on liver histology, 30 male hamsters were allocated to 2 groups of 15 animals each; one group was treated with Urso, and the other one acted as control. Thirty days later, a light and electron microscopy study of the liver of all the animals was performed. All the group receiving Urso acid revealed minimal changes consisting in hepatocytic nuclear vacuolization around the centrelobulilla area; the vacuoles were homogeneous and contained a pale basofilic material. Neither inflammatory lesions nor hepatic cell necrosis was observed. Electron microscopy showed folding of the nuclear membrane corresponding to vacuoles observed under light microscopy. Further studies must be carried out to make clear the meaning of our findings and to confirm or otherwise rectify Urso inocuity on the liver of hamsters.

RESUMO

Para investigar la accion del acido ursodesoxicolico (Urso) sobre la histologia hepatica, 30 hamsters machos fueron agrupados en 2 lotes de 15 cada uno administrandosele a un grupo 39 mg./k/dia de Urso, sirviendo el otro lote como control. Despues de 30 dias se realizo estudio con microscopia de luz y electronica de todos los higados. En el grupo que recibio Urso se comprobo en un 100 x 100 de ellos cambios minimos consistentes en vacuolizacion nuclear de los hepatocitos del sector centrolobulillar; las vacuolas eran homogeneas y contenian un material debilmente basofilo. No se observaron lesiones inflamatorias ni necrosis hepatocelular. La microscopia electronica determino la presencia de invaginaciones de la membrana nuclear, correspondiente a las vacuolas observables con el microscopio de luz. Futuros estudios deberan realizarse para aclarar el verdadero significado de nuestros hallazgos y ratificar o no la inocuidad del Urso sobre el higado del hamster
