ABSTRACT
Using a direct colorimetric method the concentration of magnesium in amniotic liquid was determined in 150 pregnant women at gestational ages ranging from 9 to 41 weeks. Results revealed a men value of 1.7 mg/dl (s = 0.39).

Monitoring of blood barbiturate level was performed in 32 term newborns, who received 6 mg/Kg/die phenobarbital (PB), by assaying blood and urine samples. Cases were grouped according to duration of treatment which varied following multiples of 12 hours from 16 to 100 hours. Serum and urine PB assay was conducted through immunological percentage nephelometric inhibition. Plasma and urine PB levels within each group were significantly correlated (r = 0.8826; p less than 0.001), indicating that, if PB treatment is given without variations in dosage and if diuresis is not impaired, blood barbiturate level may be monitored through urine assays.

18 neonatal colostrum samples were analyzed by urea-starch-gel electrophoresis to determine their casein patterns. It was found that precise typing of both alpha-and beta-casein could be obtained after the secretory burst. This genetic marker can be employed at the family level.

Urea-starch-gel electrophoresis was used to examine 175 casein samples, 130 collected at random from women from the urban area of Turin, and 45 from women resident in villages in the Sardinian hinterland. Two polymorphic systems controlling alpha- and beta-casein were demonstrated in both groups, together with similar gene frequencies for individual alleles. In addition, a rare variant was discovered in the Sardinian group.
