Long-term study of serum glycosyl-transferase levels in pregnant women and their newborn infants.

1. The authors have studied changes of glucosyl-, galactosyl- and sialyl-transferase activities in the sera of women during pregnancy and the early post-partum period, and in neonates from birth to 1 yr of age. 2.

Characterization of the human syncytiotrophoblast plasma membrane associated components.

A purification procedure of synctiotrophoblast plasma membrane (STPM) has previously been described. We now report a further characterization of their associated components. By immunochemical analysis two groups of proteins were found.

Glucosyl and galactosyl transferase activities of diabetic (db/db) and obese (ob/ob) mice kidneys.

1. Glucosyl and galactosyl activities were determined in kidney cortex tissue prepared from two strains of mice, genetically diabetic and obese mice. 2.

[Influence of vitamin A on the distribution of glycosaminoglycans in rat tissues].

Glycosaminoglycans (GAG) from brains, intestines, livers and skin of rats were analyzed by electrophoretic and enzymatic methods. Variations in GAG distribution have been studied in rats fed on a vitamin-A-deficient diet and on a diet supplemented with an excessive quantity of vitamin A. Hypervitaminosis A resulted in a decrease in GAG isolated from connective and hepatic tissues.
