Inorganic Sulphur Concentration in the Blood Serum of Normal Pregnant Women

The Copper and Copperoxidase Content of Maternal and Infant Umbilical Arterial and Venous Blood Serum at Delivery

“…These values are higher than those obtained in earlier studies in which the m aternal serum, at term , was found to contain two to three times the normal adult concentration of copperoxidase [19,33]. The age, race and parity of the pregnant woman seem to have no influence on the serum copper oxidase concentrations, a finding which confirms the results of De Jorge [7].…”

Dietary magnesium intake and the concentration of magnesium in plasma and erythrocytes of postpartum women.

“…The decrease in plasma magnesium as pregnancy pro ceeds has been observed by a number of other researchers [19][20][21]. The lower concentrations are due in part to the increased blood volume during pregnancy [ 19].…”

“…The decrease in plasma magnesium as pregnancy pro ceeds has been observed by a number of other researchers [19][20][21]. The lower concentrations are due in part to the increased blood volume during pregnancy [ 19]. De Jorge et al [19] concluded, however, that when plasma magnesium concentration is corrected for the hemodilution that occurs during pregnancy, hypomagnesemia is real during the first half of pregnancy and during the last month.…”

“…The lower concentrations are due in part to the increased blood volume during pregnancy [ 19]. De Jorge et al [19] concluded, however, that when plasma magnesium concentration is corrected for the hemodilution that occurs during pregnancy, hypomagnesemia is real during the first half of pregnancy and during the last month. For both of our groups of women plasma magnesium concentration was significantly (P < .05) lower at delivery than at 37 wk of gestation.…”

Nutrition and Pregnancy

“…Maternal serum copper levels rise throughout pregnancy (DeJorge et al, 1965;Do-Kumov, 1968). This rise is due, at least in part, to increasing estrogen levels.…”
