title: Studies of normal and prematurely ruptured human amniotic membranes: low calcium and magnesium in prematurely ruptured membranes.
abstract: Prematurely ruptured amniotic membranes at term, and membranes from normal term pregnancies were studied. The membranes were analyzed for neutral sugars, hexosamines, sialic acid, uronic acid, DNA, RNA, cholesterol, phospholipids, calcium, magnesium, sodium and potassium. The only significant difference found between the normal and the prematurely ruptured membranes was a significantly lower concentration of calcium and magnesium in the latter group. (Calcium 0.32 +/- 0.07, vs. 0.24 +/- 0.07, p less than 0.05; Magnesium 0.30 +/- 0.19 vs. 0.15 +/- 0.04, p less than 0.05; in mg/100 mg protein). The possible metabolic effects of low calcium and magnesium may be of relevance to the pathogenesis of premature rupture of the amniotic membranes.
