Serum prealbumin levels were determined in a sample of newborns suffering from infectious diseases of bacterial origin. The diagnostic and prognostic significance was assessed.
The influence of salivary pH on the estimate of blood barbiturates obtained by measuring phenobarbital on saliva at newborn age.
Serum prealbumin standards for the first and sixth days of life have been determined by immunoprecipitation ascertained with kinetic nephelometry in two samples of healthy newborns, born at term and of normal weight.

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.
Investigation on the genetic polymorphism of human casein at the population level resulted in the identification of a new variant within the beta-casein system. This discovery throws new light on the type of genetic control applicable to beta-casein.
Urea-starch-gel electrophoresis of casein samples from women of the Kikuyu tribe (central Africa) shows that this Negroid population had the same alpha- and beta-casein polymorphic pattern as Caucasoids, though their gene frequencies for the beta-locus were inverted. A new beta-casein variant (named beta-E) was identified.
The genetic polymorphism alphas1-, beta- and kappa-caseins was examined by gel electrophoresis in two Italian breeds, Valdostana and Piedmont. The results obtained from acid and basic migration show that the gene frequencies of the two breeds are very similar. Non independent assortment of genotypes among these milk protein loci was also studied. Results of analyses carried out on loci pairs showed that the genetic complex alphas1-CnB - beta-CnA2 was the most common in both breeds. In addition, the measure of linkage disequilibrium or gametic association (denoted delta) showed a close association between alphas1-Cn and beta-Cn, and between beta-Cn and kappa-Cn. No significant association was found between alphas1-Cn and kappa-Cn. This is in line with the model proposed by Grosclaude et al. (1973).

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.
