Serotonin has been shown to alter the intestinal transport of ions and intestinal motility. These effects may interfere with each other, modulating the whole physiology of the intestine. We have previously shown that serotonin also alters the transpo

The effect of uranyl on sugar transport across rat jejunum has been studied in vitro and in vivo. D-glucose and D-galactose accumulation in jejunum rings at pH 6.0 is inhibited about 40-65% by 1 mM uranyl nitrate. This inhibition is lower than that p

Cupric ions inhibit galactose absorption by in vivo perfused rat jejunum. It takes some delay for the inhibitory action to display its maximal levels, and previous exposure of the mucosa to Cu markedly increases inhibition. Copper effects were only s

Absorption of galactose from in vivo perfused rat jejunum was inhibited by 0.1-0.5 mM Hg2+. A few minutes' delay was required for maximal inhibition values. The effects remained after saline solution washing but were in part reversed by EDTA and in h

Galactose absorption by rat jejunum perfused in vivo is inhibited by 0.5 mM Cd2+. This effect is explained by impairment of the phlorizin-sensitive sugar transport system, as Cd does not modify the absorption of L-sorbose or that of galactose in the

Cd2+, Cu2+ and Hg2+ (0.5 mM) inhibit the absorption of D-galactose (1 mM) across rat jejunum in vivo. The inhibition increases by 3-5 min previous exposure of the mucosa to the heavy metals, and is appreciably reversed by washing the intestinal lumen

D-galactose absorption during 1 min perfusion periods was not affected by the presence of 10(-7)-10(-8) M VIP in the sugar solution, but exposure of mucosa to VIP for 5 min inhibited sugar absorption in the subsequent periods of perfusion. This inhib
