Does monochloramine selectively inhibit the transient outward potassium current in colonic smooth muscle?
NH(2)Cl selectively inhibits I(TO) at concentrations within the range that are produced during colitis. Suppression of I(TO) by NH(2)Cl in SMCs occurs by an effect on the channel alpha subunit mediated from within the cytosol. Oxidant-induced changes in ion channel activity in colonic SMCs may contribute to abnormal motility in colitis.
An elemental diet for 2 weeks resulted in a clinical improvement in patients with active rheumatoid arthritis, and was as effective as a course of oral prednisolone 15 mg daily in improving subjective clinical parameters. This study supports the concept that rheumatoid arthritis may be a reaction to a food antigen(s) and that the disease process starts within the intestine.
