LDH isoenzymes and heat-stable alkaline phosphatase were studied in the serum and placental extract of 20 cases of pre-eclampsia and 10 normal pregnancies as a control. The starch-gel electrophoretic serum and placental isoenzymogram showed that LDH4 and LDH5 were the main isoenzymes in the placenta
The aim of this work was to determine the levels of urinary human tissue non-specific alkaline phosphatase (hTNAP) in pre-eclampsia and eclampsia in order to assess renal tubular damage. Urine samples were collected from 26 mild pre-eclamptic, 26 were pre-eclamptic, 20 eclamptic patients and 20
This is a study of heat-stable alkaline phosphatase (HSAP65degreesC) concentrations in the serum of pregnant women with hypertension (42 cases), mild preeclampsia (40 cases) and severe pre-eclampsia (22 cases). The results are seen in relationship to the occurrence of intrauterine fetal death,
BACKGROUND
The precise origin of Pre-eclampsia (PE) remains elusive. Multiple pieces of evidence support the existence of hypoxia in PE. MiRNA-210 (miR-210), which is induced by Hypoxia-Inducible Factor-1α (HIF-1α) during hypoxia, is one of the most hypoxia sensitive miRNAs. MiR-210 mediates these
The authors studied 74 pregnant women with preeclampsia presenting various degrees of gravity. The activity of alkaline phosphatase was determined cytochemically in the leucocytes. It was established that the activity of the enzyme was unchanged in mild preeclampsia and diminished progressively with
Total alkaline phosphatase (AP) was measured in maternal plasma, cord plasma and placental extracts in normal and in pre-eclamptic pregnancies. Total plasma AP was significantly elevated during the last two trimesters in normal and pre-eclamptic pregnancies, but contrary to previous reports, both
The purpose of the present study was to localize glucose-6-phosphatase (G6Pase) activity in the human placenta at various gestational stages and to compare them to pre-eclamptic placenta activity. Ultrastructural enzyme-histochemical analysis of G6Pase was performed using cerium and lead as
The subcellular localisation of acid and alkaline phosphatase has been studied in the trophoblast of placentae from both normal and complicated pregnancies. In placentae from uncomplicated pregnancies the number of trophoblastic acid-phosphatase-containing organelles decreases progressively as
A novel poly(vinyl chloride) matrix membrane sensor responsive to 4-nitrophenylphosphate (4-NPP) substrate is described, characterized and used for the potentiometric assay of acid (ACP) and alkaline (ALP) phosphatase enzymes. The sensor is based on the use of the ion-association complex of 4-NPP
Serum levels of placental alkaline phosphatase (PLAP), human placental lactogen (HPL) and oestriol (E3) were investigated in 33 women with high-risk pregnancies. In pregnancies complicated by intrauterine growth retardation (IUGR) low PLAP values were constantly recorded. HPL values showed a similar
To measure changes in bone alkaline phosphatase (EC 3.1.3.1) activity in serum as a function of duration of pregnancy, we adapted our existing alkaline phosphatase (ALP) isoenzyme assay (which has been used to measure bone, hepatic, and intestinal ALP activities in serum, in the absence of placental
Estimation of the alkaline phosphates isoenzymes in paired maternal serum and amniotic fluids in term uncomplicated pregnancies and in patients with pre-eclampsia, showed poor correlation coefficients between the levels of both heat stable and heat labile isoenzymes. There was a statistically
