title: The effect of auranofin on the colonic transport of Na+ and fluid in the rat.
abstract: Auranofin in the mucosal fluid caused a dose-dependent inhibition of fluid and Na+ absorption by everted sacs of rat colon. Serosal auranofin was without effect. (Na+ + K+)ATPase activity of homogenates of mucosal scrapes of rat colon was inhibited by auranofin in a dose-related manner, while Mg2+-ATPase activity was little affected. These actions of the drug on colonic transport mechanisms could contribute to the diarrhoea associated with auranofin therapy.
