Mucosal hypoxia is a common endpoint for many pathological processes including ischemic colitis, colonic obstruction and anastomotic failure. Previous studies suggest that hypoxia modulates colonic mucosal function through inhibition of chloride secretion. However, the molecular mechanisms underlying this observation are

Gastric secretion of hydrochloric acid requires protons and chloride, yet the mechanisms and regulation of gastric chloride secretion remain unclear. We developed an in vivo technique to simultaneously measure acid/base and chloride secretion into the gastric lumen of anesthetized rats.

A class of N-substituted quinoline compounds has been introduced recently for the fluorescence measurement of Cl concentration in biological preparations. The most Cl-sensitive compound was 6-methoxy-N-[3-sulfopropyl] quinolinium with peak excitation and emission wavelengths of 350 and 442 nm and a
