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).
对50例患者活检标本中的十二指肠黏膜镁含量进行了估算，其中43例黏膜组织病理学正常。组织病理学正常和异常的标本，其平均黏膜镁含量无显著差异，总体平均值为每千克干重组织30.9毫摩尔，但数值分布范围较广。还测定了血浆和十二指肠液中的镁浓度。十二指肠黏膜镁含量与血浆镁浓度之间无显著相关性。然而，十二指肠液中的镁含量与十二指肠黏膜之间存在微弱但具有统计学意义的相关性（r = 0.54，p < 0.001）。
