[The prognostic meaning of the selection parameters amniotic fluids samples and frequency occurrence respiratory distress newborn].

Prenatal diagnosis of amniotic fluid enables the evaluation of fetal lungs maturity. The aim of the study is to evaluate prognostic significance of measurement of concentration of lamellar body count (LC) in comparison with other laboratory investigations for prenatal fetal lung maturity evaluation. The study was carried out on 60 amniotic fluid collections obtained by amniocentesis of pregnant women, hospitalized in Polish Mother's Health Centre between August 1998-January 2000.

[Alpha-amylase/glucose index in amniotic fluid as a new method in prenatal assessment of fetal maturity].

Prenatal diagnosis of amniotic fluid enables fetal maturity evaluation, particularly that of fetal lungs. The aim of the study is to evaluate the diagnostic value of on alpha-amylase/glucose index in amniotic fluid in comparison to routinely performed tests, used for prenatal fetal lung maturity evaluation, particularly in respect of PG concentration, whose predictive value is almost 100%. The study was carried out on 180 pregnant women, chosen by random selection, hospitalized in Polish Mother's Health Centre Hospital in the period from 15.

[Diagnostic significance of index alpha-amylase/glucose in amniotic fluid in prediction of fetal maturity].

An increase in alpha-amylase activity with parallel decrease in glucose concentration in amniotic fluid is observed during pregnancy. This interdependence is a theoretical basis for using an alpha-amylase/glucose index in fetal maturity evaluation. The aim of the study was to investigate usefulness of the alpha-amylase/glucose index in amniotic fluid in prenatal fetal maturity diagnosis.

[Prenatal evaluation of fetal lung maturity by determination of phosphatidylglycerol (PG) concentration in amniotic fluid].

Phosphatidylglycerol (PG) is considered to be the most important phospholipid of lung surfactant, responsible for its biological activity. The aim of the study was to investigate the predictive value of phosphatidylglycerol (PG) concentration in amniotic fluid in prediction of neonatal lung maturity. The study was carried out on 180 pregnant women, chosen by random selection, hospitalized in Polish Mother's Health Centre Hospital in the period from 15.

[Metabolic disorders in children with urolithiasis].

Nephrolithiasis is a common disease of multifactorial ethiopatogenesis. The majority of stone formers has disturbances in the metabolism and excretion of stone constituents, promotors or inhibitors of crystallization. The aim of our study was to evaluate metabolic disturbances in children with nephrolithiasis in the early stages of the disease.
