Introducción. El colon es un blanco clásico de la aldosterona, pero su efecto sobre el consumo de oxígeno (QO2) del epitelio se desconoce. Objetivos. Evaluar el efecto del bloqueo de canales epiteliales de sodio (ENaC) sobre la corriente de cortoc

Background/Aim: Aerobic metabolism is necessary for ion transport in many transporting epithelia, including the human colonic epithelium. We assessed the effects of the epithelial sodium channel blocker, amiloride, on oxygen consumption and short-cir

La hipoxia hipobárica crónica es un estresante ambiental fisiológico. Aunque sus efectos se han estudiado en la mayoría de los sistemas orgánicos, hay pocos trabajos sobre su influencia en el transporte intestinal. Se estudió el efecto del bloq

Background Both chronic hypoxia and mineralocorticoids independently stimulate electrogenic sodium absorption in rat distal colon It is hitherto unknown whether there is any interaction between these two stimuli The aim of this work was to assess the

AIM To assess whether higher sensitivity of colonic epithelium to hypoxia at the serosal side is associated with oxygen transfer asymmetry. METHODS Rats were fed either with normal chow or a low-sodium diet. Tissues were mounted as flat sheets in a m

The aerobic metabolic cost of chloride secretion was studied in rat distal colon isolated mucosa under several conditions by simultaneous measurement of short-circuit current and oxygen consumption under conditions that preserve vectorial ion transpo

Chronic hypoxia induces many physiological changes, but little is known about its effects on colonic epithelial function. Isolated distal colon mucosa from rats under normobaric conditions and rats submitted to hypobaric hypoxia for either 4 or 10 da

The contributions of subepithelial tissue, mucosa, and mucus gel layer as restraints for oxygen diffusion in rat distal colon in vitro were assessed by comparing oxygen transfer through preparations of isolated submucosa, isolated mucosa with and wit

Background and Aims In isolated colonic mucosa, decreases in short-circuit current (ISC) and transepithelial resistivity (RTE) occur when hypoxia is either induced at both sides or only at the serosal side of the epithelium. We assessed in human colo

It is recognized that epithelial ion transport depends on oxygen supply, but this dependence has not been characterized in the human colon in vitro despite its surgical and clinical implications. The aim of this study is to measure the oxygen consump
