Abstract:
Serum vitamin E was determined using bathopllenanthroline by microspe-ctrophotometric method. The average recovery rate was 93.8 (92.2-98.0) per cent and the coefficients of variation were 2.5 and 7 per cent in high and low levels respectively. This method seems to be quite reliable and sensitive. Of the total 117 serum samples, 30 pairs matched blood for mother and cord, 27 cord blood, and 30 normal adults as control were studied. The mean level of vitamin E in the cord blood was 2.8 ug/ml (?0.9SD), which was about one third of that in the adult. The level of vitamin E in post-partum mother was 12 ?g/ml (?2.5 SD), which was significantly higher than that of nonpregnant women (p
