[Activity of aminopeptidase and inter-alpha-trypsin inhibitor in serum of women in physiological labor]. / Aktywnosc aminopeptydazowa i stezenie inter-alfa-inhibitora trypsyny w surowicy krwi kobiet w okresach porodu fizjologicznego.

Aminopeptidase activity was measured towards L-alanine and L-leucine naphtylamides in the blood serum obtained from the non-pregnant women and from women during the stages of the physiological delivery. In the same samples the concentration of inter-alpha-trypsin inhibitor (alpha ITI) was measured. The highest aminopeptidase activity was observed in the stage II, and it was statistically significant comparing to the stage I, whereas the statistically significant increase in the alpha ITI concentration was noticed in stage I in primiparae and in stage I in multiparae.

[Urinary trypsin inhibitor in pregnant women with normal and pathological course of pregnancy]. / Inhibitor trypsyny w moczu kobiet w ciazy fizjologicznej i patologicznej.

Urinary trypin inhibitor concentration (UTI) was measured by Fritz and all method in the groups of women: non-pregnant (I), pregnant (II), in pregnancy complicated by EPH-gestosis (III) and in the prolongated pregnancy (IV). Furthermore, in the urine from the investigated group the index protein/creatinine was established. There was noticed the statistically significant increase in the UTI concentration in II, III, IV groups comparing to the non-pregnant group--I, and the increase in UTI in III and IV group in comparison to group II. The UTI measurement in the pregnant women connected with the index protein/creatinine could be significant for diagnosing of the pathology of pregnancy.

[Aminopeptidases activity in the amniotic fluid in women in labor with EPH-gestosis]. / Aktywnosc aminopeptydazowa w plynie owodniowym rodzacych z EPH-gestoza.

The thesis of this work was to compare the aminopeptidases activity in the amniotic fluid obtained during the physiological labor and during the labor of pregnant with EPH-gestosis, in presence of the beta-naphtlamidic L-amino-acids (alanine, leucine, phenylalanine, tyrosine, histidine, cysteine) chromogenic substrates. It was assumed the 3-7 times increase in the aminopeptidases activity counted to the proteins from the labored with EPH-gestosis comparing to the labored in physiological labor. Among the used substrates the highest activity in both groups of labored women was measured in presence of substrates with exact amino-acids in this order: L-Ala > L-Leu > L-Phe > L-Tyr > L-His > L-Cys.

[Concentration of cysteine proteinase inhibitors in urine, amniotic fluid and serum from women in pregnancy complicated by EPH-gestosis]. / Stezenie inhibitorów proteinaz cysteinowych w moczu, plynie owodniowym i surowicy kobiet w ciazy powiklanej EPH-gestoza.

Cysteine proteinase inhibitors (IPC) concentration was measured by the modified Barrett method using papaine in urine, amniotic fluid and serum obtained from the healthy labored women and from labored women in pregnancy complicated by EPH-gestosis. It was noticed the statistically significant increase in the IPC concentration in the material from the pregnant women with EPH-gestosis comparing to the women, which pregnancy had the physiologically normal course.

[The arylsulphatase A (EC 3.1.6.1) activity in serum, urine and amniotic fluid from pregnant women with EPH-gestosis]. / Aktywnosc arylosulfatazy A (EC 3.1.6.1) w surowicy, moczu i plynie owodniowym kobiet ciezarnych z EPH-gestoza.

In serum, urine and amniotic fluid obtained from the 52. women divided into three groups the arylsulphatase A (EC 3.1.6.1) activity was measured by the modified Lee-Vaupel and Conzelmann method. It was noticed in serum from the pregnant women with EPH-gestosis the statistically significant (p < 0.05) increase in the enzyme activity comparing to the results from non-pregnant women and pregnant with normal course of pregnancy. It was no statistically significant differences in the urine from pregnant with EPH-gestosis and from the healthy pregnant, but there was the increase (p < 0.01) in the enzyme activity in amniotic fluid from pregnant women with EPH-gestosis comparing to the physiological course of pregnancy. According to our data, the arylsulphatase A activity assay could be recommended as a diagnostic marker in the EPH-gestosis.
