In this study,
urinary kallikrein quantity and activity were measured by the
kallikrein direct RIA and
kininogenase activity with human
low molecular weight kininogen in 32 non pregnant healthy women, 20 normal 3rd trimester pregnant women and 18 3rd trimester
hypertension type
toxemia patients. There was no significant difference in
urinary kallikrein quantity between non pregnant women (n = 32, 64.0 +/- 6.3 micrograms/day, mean +/- SE) and normal pregnant women (n = 20, 68.1 +/- 10.1 micrograms/day). There was a significant difference (p less than 0.001) between non pregnant women and
toxemia patients (n = 18, 22.5 +/- 3.3 micrograms/day). There was a significant difference (p less than 0.001) between
toxemia patients and normal pregnant women. There was a significant difference (p less than 0.05) in
urinary kallikrein activity between non pregnant women (n = 32, 496.2 +/- 57.2 micrograms
kinin/day) and normal pregnant women (n = 20, 319.5 +/- 48.1 micrograms
kinin/day). There was a significant difference (p less than 0.0001) between non pregnant women and
toxemia patients (n = 18, 82.6 +/- 13.6 micrograms
kinin/day). There was a significant difference (p less than 0.01) between normal pregnant women and
toxemia patients. There were no correlation in both
urinary kallikrein quantity and activity between severe type
toxemia patients (systolic blood pressure greater than or equal to 160mmHg or diastolic blood pressure greater than or equal to 110mmHg) and mild type
toxemia patients (160mmHg greater than systolic blood pressure greater than or equal to 140mmHg and 110mmHg greater than diastolic blood pressure greater than or equal to 90mmHg).(ABSTRACT TRUNCATED AT 250 WORDS)
