Taurocholate transport was studied in brush border membrane vesicles (BBMV) isolated from chicken small (duodenum, jejunum, and ileum) and large (proximal cecum and rectum) intestines, using a rapid filtration technique. The purity of the BBMV was verified by the finding that the specific activity of sucrase (a brush border membrane enzyme...

Kinctics of Glycylsarcosinc (Gly-Sar) uptake by isolated chicken enterocytes was studied by measuring irs intracellular concentration, and by discriminat ing betwccn the saturable and rhe diffusive components of the total uptake. The diffusive component was greater at pH 6.0 than at pH 7.4, and the J max was also increascd by lowering...

Jejunal and ileal absorption of L-leucine has been studied in rats subjected to jejunoileal bypass and in sham-operated rats, for five minute periods, using a perfusion technique. Aminoacid concentrations were: 1, 2.5, 5, 10 and 25 mM. In sorne experiments methionine was added to determine simple diffusion. The ratio of the active/diffusive...

It is well known that surgical resection of the small bowel results in adaptive changes in the residual intestine (7, 13, 14). The entero-hepatic circulation of bile saits, which is responsible for main­ taining constant bile salt pool, is also impaired by intestinal resection. Bile salts are largely reabsorbed by an active...

Este trabajo describe la actividad docente desarrollada por los profesores de la asignatura de Fisiología Celular de la Facultad de Farmacia, durante el Curso Académico 1997-98, coincidiendo con la implantación del Nuevo Plan de Estudios de la Licenciatura de Farmacia. El desarrollo de la aplicación de la actividad tuvo como objetivo aplicar...

The transport system of folic acid (Pte-Glu) b y brush-borde r membrane vesicles (BBMV ) isolated from prawn (Penaeus japonicm) hepatopancreas , was studied by measuring the uptake of Pte-Glu . This uptake was found to have two components , intravesicular transport and membrane binding . Membrane binding was not affected by the presence of a...

Coincidiendo con la implantación del Nuevo Plan de Estudios de la Licenciatura de Farmacia durante el Curso Académico 1997-98, los profesores de la asignatura de Fisiología Celular de la Facultad de Farmacia decidimos utilizar programas de ordenador interactivos, basados en la tecnología multimedia, para la enseñanza práctica de la mencionada...
