Biochemical determinations of arylsulphatase A activity and sulphatide concentrations in decidua of women at 41 and 42 weeks of gestation.
OBJECTIVE
To evaluate arylsulphatase A activity and sulphatide concentrations in decidua of women at 41 and 42 weeks of gestation.


METHODS
Enzyme activity and sulphatide concentrations were determined by biochemical procedures on samples of women at 41 and 42 weeks of gestation; thin-layer chromatography was also prepared to separate and visualize sulphatides and other lipid fractions.


RESULTS
The spectrophotometric values of arylsulphatase A showed very low values at 41 weeks, which reduced to a half at 42 weeks of gestation, while values of sulphatide concentrations increased in 42 weeks.


CONCLUSIONS
The behavior of two parameters examined could be due to the amount of placental estriol reduction, because of sudden placental aging.
