Three-hour constant-rate intravenous infusion into rabbits of 1-3 mg prostaglandin E1 (PGE1) per kilogram markedly increased plasma fibrinogen 24 h later. 131I-labeled fibrinogen and model studies showed increased synthesis underlay this. Similar PGE1 doses lowered systolic blood pressure. Maintaining systolic blood pressure by infusing noradrenaline with the PGE1 did not alter plasma fibrinogen response to PGE1; plasma fibrinogen was unchanged by noradrenaline infusion. Regression equations relating plasma fibrinogen increment to PGE1 dose, plasma fibrinogen increment to dose and systolic blood pressure change, and systolic blood pressure change to dose are given as well as the constants relating plasma fibrinogen increment to dose using the Michaelis-Menten equation. Infusions of cyclic AMP, dibutyryl cyclic AMP, and cyclic GMP intravenously led to only small plasma fibrinogen increases. Daily intravenous infusions of PGE1 led to loss of both plasma fibrinogen and systolic blood pressure responses in two animals; a third animal showed only loss of the former and a fourth only loss of the latter response. PGE1 slightly enhanced the small plasma fibrinogen increase following intravenous bradykinin. Approximate arterial blood PGE1 concentrations resulting from the intravenous infusion of 1 mg mg PGE1 kg-1 3 h-1 are calculated. These are compared with measured values.

Sham Control

Introduction: Catheter-based ablation of renal artery has been studied as one of the interventions for blood pressure control in patients with uncontrolled hypertension. Previous randomized control trials (RCTs) comparing renal denervation versus sham procedure for the same have shown equivocal results. This meta-analysis summarizes the current evidence on the effect of sham-controlled renal denervation on blood pressure reduction. Methods: Pubmed, Embase and Cochrane Central databases were searched from inception until April 30, 2020. RCTs comparing catheter-based renal denervation with a sham control were included. Outcomes assessed were changes in ambulatory systolic blood pressure, change in ambulatory diastolic blood pressure, change in office systolic blood pressure and change in office diastolic blood pressure. Weighted mean differences (WMD) were calculated and pooled using inverse variance method into a random effect model meta-analysis. Results: Six studies with 1118 participants were included in the analysis. Catheter based renal denervation was associated with significant decrease in ambulatory systolic blood pressure (WMD: -3.71; 95% CI: -2.32 to -5.11, p value <.00001) and ambulatory systolic blood pressure (WMD: -1.71; 95% CI: -0.59 to -2.82, p value=0.003) compared with sham. The reduction in office systolic and office diastolic blood pressure was also significantly greater with catheter renal denervation than sham control (WMD: -5.82; 95% CI: -3.67 to -7.92; p value<0.00001 and WMD: -3.51; 95% CI: -2.29 to -4.73; p value<0.00001 respectively) Conclusion: This meta-analysis showed significant benefit of catheter-based renal denervation for uncontrolled hypertension for all the studied outcomes. Based on this data patients with uncontrolled hypertension, on lifestyle and pharmacological management may benefit from catheter-based renal denervation

1. Orthostatic hypotension, an age-related phenomenon, has been associated with hypertension and body weight variability. To evaluate the relative contributions of blood pressure elevation and abnormalities in extracellular volume regulation to orthostatic hypotension, elderly institutionalized subjects (mean age = 87 ± 7 years), taking no cardiovascular medications, underwent measurement of body weight (n = 15) and first morning supine and standing blood pressures (n = 19), 12–13 times per subject over a 2–4 week period. 2. There was a wide day-to-day variability in postural systolic blood pressure change (coefficient of variation = 533%) and a strong negative correlation between each day's postural change in systolic blood pressure and basal supine blood pressure (r = −0.55, P < 0.0001). 3. There was no association between postural blood pressure change and heart rate response or body weight changes, which were very small over the duration of the study (coefficient of variation = 0.6%). 4. Elderly individuals have intact homoeostatic mechanisms for the control of standing pressure when basal blood pressure is normal. Postural hypotension in the elderly is a variable phenomenon related to elevations in basal blood pressure.

Tomato is one of diets that is rich of nutrition. Moreover, tomato has an important role to keep body balance, tomato also can be used to cure hypertension. Tomato contains potassium, calcium, and other nutrition that can decrease blood pressure of menopause women. This study is aimed at knowing the influence of tomato juice towards blood pressure change of menopause women. The sample used in this study is 16 respondents. The design of the study is pre experimental with one group pre-test and post-test approach. The data analysis used in this study is Wilcoxon test. The result of the study shows that there is an influence of tomato juice towards the decreasing of systolic blood pressure of menopause women in campurejo-mojoroto-kediri. It is hoped that the result of this study will give a beneficial contribution to menopause women and other hypertension sufferers.Keyword: Hypertension, Tomato, Potassium, Calcium
