Abstract
|
|
|
human milk is believed to be the most nearly complete and perfect food for the human infant. The mineral content of human milk is low but its bioavailability is generally higher than that of infant formulas.
Iron, zinc and copper are essential trace elements, they constitute enzymes and their activators and play an important role in human growth, development and normal metabolism. Iron, zinc and copper levels in human milk and serum and hair of
neonates
were measured by atomic absorption spectrophotometer.
@ES The results were as follows;
@EN 1) Iron concentration was 58.4±14 ㎍/dL in colostrum, 53.9±10㎍/dL in early transitonal milk, 45.8±21 ㎍/dL in late transitional milk, 36.0㎍13 ㎍/dL in early mature milk, 32.0㎍16 ㎍/dL in late mature milk, 175.24±25.68㎍/dL in serum of
neonates and 31.31±71.07 ㎍/gm in hair of neonates.
2) Zinc concentration was 7.45±1.20 mg/L in colostrum, 6.43±1.89 mg/L in early tranitional milk, 4.56±1.55 mg/L in late transitional milk, 4.22±1.11 mg/L in early mature mil, 3.21±23.37 ㎍/gm in hair of neonates.
3) Copper concentration was 0.62±0.43 mg/L in colostrum, 0.59±0.32 mg/L in early transitional milk, 0.64±0.17 mg/L in late transitional milk, 0.48±0.13 mg/L in early mature milk, 0.46±0.15 mg/L in late mature milk, 50.30±12.5 ㎍/dL in
serum
of
neonates and 5.15±6.26 ㎍/gm in hair of neonates.
