The Mean

These studies were performed to see if jejunal malabsorption of magnesium in patients with chronic renal disease was influenced by therapy with 1 alpha, 25-dihydroxyvitamin D3 [1,25-(OH)2D3; 2 microgram/day by mouth for 7 days]. This treatment restored normal serum concentrations of the vitamin D metabolite from 0.9 +/- 0.2 to 4.2 +/- 0.6 ng/dl. Jejunal absorption of magnesium, measured by a triple-lumen constant-perfusion technique, was enhanced in each of the seven patients by this therapy. The mean value rose from 0.04 +/- 0.02 to 0.13 +/- 0.02 mmol . 30 cm-1 . h-1. This last value is similar to the magnesium absorption rate in untreated normal subjects. These results demonstrate that magnesium absorption in the human jejunum is dependent on vitamin D, and they show that 1 alpha,25-dihydroxyvitamin D3 therapy in patients with chronic renal failure is associated with an enhanced jejunal absorption of magnesium.

Stimulation Of

At low doses angiotensin III (A III) stimulates jejunal fluid absorption in the pentobarbital sodium-anesthetized rat. In contrast, at high doses the hormone inhibits absorption and/or stimulates secretory processes. The stimulation of jejunal absorption in response to A III can be blocked by guanethidine, phentolamine, and prazosin but not by propranolol or yohimbine, suggesting that A III-increased intestinal absorption is secondary to the release of norepinephrine from sympathetic nerves in the jejunum and activation of postsynaptic alpha 1-adrenergic receptors. The A III inhibition of water absorption is not affected by adrenergic antagonists but can be reversed to a net stimulation of transfer after pretreatment of the animals with indomethacin. This suggests that at high doses A III stimulates intestinal prostaglandin biosynthesis. The A III analogue [Ile7]A III is devoid of agonist activity over a wide dose range and behaves as a potent antagonist of both the stimulatory and the inhibitory effects of the parent peptide on jejunal absorption. [Ile7]A III will be a useful tool for investigating the physiological role of angiotensin peptides in the control of intestinal absorption.
