The magnesium content of duodenal mucosa in man.
The magnesium content of duodenal mucosa was estimated in biopsy specimens from 50 patients, 43 of which had normal mucosal histopathology. There was no significant difference in the mean mucosal magnesium content of those speciments with normal and abnormal histopathology and overall the mean value was 30.9 mmol/kg dry weight of tissue, but there was a wide spread of values. The concentration of magnesium in plasma and duodenal fluid was also determined. There was no significant correlation between duodenal mucosal magnesium content and plasma magnesium concentration. However, there was a weak but statistically significant correlation between magnesium content in duodenal fluid and duodenal mucosa (r = 0.54, p less than 0.001).
