RESUMEN
The nutritional status, serum lipids, protein, Ca, and Zn of 85 toxemic and 42 normal pregnant women were estimated longitudinally from the first trimester to delivery. The results of dietary survey revealed that correlative and regressive relationship closely existed between serum TC, LDL-C, LDL-C/HDL-C, AI, and percentage of animal fat. In the toxemic cases, there were significant increases of serum LDL-C/HDL-C, AI, and decrease of HDL-C, HDL-C/TC and Ca in the 1st trimester as compared with those of the normal. In the 3rd trimester, there were significant increases of serum TG, TC, LDL-C, LDL-C/HDL-C, AI and MUFA, and decrease of serum HDL-C, HDL-C/TC, Ca, Zn, total protein and albumin in the toxemic cases. The regressive relationship was found between GI (ges-tosis index) and serum Ca in the 1st trimester or GI and serum P/S, A/G, LDL-C/HDL-C, AI in 3rd trimester. The problem of nutritional factors on development of toxemic cases was discussed and some nutritional suggestions were made.
RESUMEN
A longitudinal study was carried out on zinc, copper, calcium, phosphorus and magnesium status of 104 normal primigravidas. The five elements in serum and hair of the mothers and their newborns were estimated with inductive coupled plasma emission spectroscopy. The results showed that the concentration of serum zinc, calcium, magnesium decreased gradually while copper and phosphorus increased remarkably in the course of pregnancy. The serum copper and phosphorus of cord blood were lower, zinc and calcium were higher than that of mothers' blood. The contents of hair zinc, copper, and phosphorus showed no differences but calcium and magnesium decreased gradually during pregnancy. Except that the level of copper in the newborns' hair was much lower, other elements were much higher than that in the mothers' hair.
