Description

The author conducted metabolic experments on nine normal pregnant women at thetemnl stage of pregnuy and on three normal latting women during 30 to 32 daysafter delivbry in order to investigate the characterstics of nitrogen, calcium and phosphorusmetabolism durng pregnancy and lactation. The results of experiments are summarizedas follows.<BR>(1) As for the nitrogen metabolism during Pregnauy, a balance from-0.3to+2.7g. is obtained by the average intake of 8.4 to 14.6 g. The accumulation rate does not increasewith the gestation month, and the rate was higher during second trimester than otherstage of prgnancy.<BR>As for the ntrogen metabolism durng lactation, the balance was from-0.1 to+1.4gat the daily intake of average 12.8 to 14.2 g.<BR>(2) There is a ba1ance of calcium metabolism from-22 to+378 mg. by the averagedaily inake of 406 to 1528 mg. during pregnancy. Calcium shortage might readily occurwith usual house meal, and therefbre it is recommendable to supplement 0.4 to 0.8 g. calciumpreparation durng Prgnancy, and a balance from-95to+616 mg. is observed forphosphorus metabolism with daily average intake of 678 to 1884 mg.<BR>As for the calcium metabolism during lactation, the balaue is between-231 to-659mg. in all cases with daily average inake of 453 to 637 mg., and for the phosphorus metabolism, the balaue is from-385 to-3 mg. with daily average intake of 1184 to 1257 mg.
