摘要:

ABSTRACT.Plasma and interstitial fluid colloid osmotic pressure (COP) and interstitial fluid hydrostatic pressure (Pi) were measured in 10 normal pregnant women in first and third trimester. Interstitial fluid COP was measured by a “wick” technique and Pi by a “wick‐in‐needle” technique. The COP was significantly lower both in plasma and interstitial fluid in the third trimester compared to that in the first trimester. However, the fall in COP was more marked in the interstitial fluid than in plasma. Only small changes in Pi were observed. Our results support the view that reduction of COP in interstitial fluid is a major local edema‐preventing mechanism. This compensates for the increased capillary pressure and the hypoproteinemia in late pregnancy. The relatively low interstitial fluid COP in third trimester women without edema implies a reduced safety margin against edema formation and may explain why 40 ‐ 80 % of normal pregnant women e

摘要:

ABSTRACT.Twenty‐one preeclamptic women had increased venous plasma‐free adrenaline (45 ± 5 vs 27 ± 2 pg/ml, mean ± SE, P<0.01) and plasma‐free dopamine (137 ± 25 vs 55 ± 6 pg/ml, P<0.01) compared with fifteen normotensive pregnant women. Plasma renin activity (P<0.001) and aldosterone concentration (P<0.02) were depressed in the preeclamptic and serum potassium increased (P<0.02). Plasma adrenaline correlated with blood pressure (r = 0.80, P<0.001) supporting increased sympathetic nervous tone in the development of pr

摘要:

ABSTRACT.In the years 1969 — 1973, 0.3% of 17000 unselected non‐diabetic pregnancies were complicated by severe pre‐eclampsia, 0.6% by mild pre‐eclampsia and 0.6% by hypertension in pregnancy. Records from affiliated maternity centers and the hospital were studied for these 261 women and for 260 women with matched normotensive pregnancies.The women with pre‐eclampsia/hypertension in pregnancy had higher blood pressure than the control group very early in pregnancy. The hypertensive women were more often primiparous and they had a slightly higher body weight. The patients with severe pre‐eclampsia were older than the other women (30.4 vs 25.4 years for controls, p<0.001). Immigrants were not more commonly found in the hypertensive groups, but unmarried mothers were more often seen in the mild preeclampsia and pregnancy hypertension groups, 19.1% and 20.6% respectively compared to 7.7% in the control group (p<0.01). A family history of hypertension was frequently reported in all groups.The most striking characteristic of women with pre‐eclampsia/hypertension in pregnancy was their elevated blood pressure before or very early

摘要:

ABSTRACT.Blood pressure at rest and cardiovascular response to “stress” were studied in 27 girls and 33 boys 11–16 years old. One group (HT, n = 23) had hypertensive mothers with a previous hypertensive pregnancy, another group (NT, n = 20) had normotensive mothers with a previous hypertensive pregnancy and the control group (C, n = 17) had normotensive mothers with normotensive pregnancies. Resting blood pressure was 124/71 mmHg (HT), 117/67 mmHg (NT) and 112/65 mmHg in the 3 groups. Systolic pressure was significantly different in all 3 groups (p<0.05 ‐ p<0.001).Responses to noise stimulation (100 dBA) were identical in all groups with increases in diastolic and mean arterial blood pressure and cardiac output. During a video game session increases in blood pressure and heart rate were equal in the groups but during physical exercise a slight decrease in diastolic blood pressure was seen in the NT and C groups only.Differences in blood pressure in children with varying maternal history of hypertension do not seem to reflect alterations in the cardiovascular response pattern to
