Pressor Substances in Arterial Hypertension

نویسنده

چکیده

Pherentasin is the only pressor substance found in blood of hypertensive patients which is not found in normal blood. This study defines its unit and compares its concentration with diastolic blood pressure level, type of hypertension, and age of patients. Lack of correlation between blood pressure level and pherentasin content suggests considerable variation in the amount of depressor substances in these patients. Chemical studies of pherentasin and its partial, tentative formula

Release of pressor substances from renal grafts originating from rats with renal hypertension.

TRANSPLANTATION of normal kidneys into 18to 24-hour nephreetomized rats caused a sharp and sustained pressor response. By contrast, transplantation of partially infarcted kidneys produced only a slight or no rise in arterial pressure. This decrease, or lack of pressor activity, in the renal vein effluent was observed within a few days after infarction before development of hypertension and pers...

T H E Reaction of Peripheral Blood Vessels to Angiotonin, Renin, and Other Pressor Agents* by Richard

One of the characteristics of the pressor substance which may cause essential hypertension in man or experimental renal hypertension in dogs must be an ability to elevate arterial pressure by constricting the arterioles sufficiently to increase peripheral resistance but not sufficiently to reduce blood flow. Clinical experience indicates that patients or animals with hypertension do not have co...

PRESSOR SUBSTANCES IN ARTERIAL HYPERTENSION III. CHEmCAL STUDIES ON PHERENTASIN*

In the first paper of this series (1) the presence of a material producing a prolonged pressor response in rats was demonstrated in crude non-protein extracts of arterial blood samples from hypertensive subjects. This study has been extended and confirmed and the pressor substance named pherentasin (2). The present report is concerned with further purification of this material and with methods ...

The Effects of Pressor Drugs and of Saline Kidney Extracts on Blood Pressure and Skin Temperature.

Many pressor substances, including hormones, drugs, and variously prepared extracts of kidney tissue, have been studied intensively to determine their effects on blood pressure and their possible role in the pathogenesis of human hypertension. Many of these experiments were performed on anesthetized animals and observations usually dealt merely with changes of systemic blood pressure. According...

The Etiology of Hypertension Due to Complete Renal Ischemia

1. Perfusates of totally ischemic kidneys of cats contain a pressor substance which is not present in the perfusates of normal kidneys, ischemic hind limbs, or ischemic gravid uteri. 2. The pressor material in ischemic renal perfusates originates directly in the kidney as a result of complete ischemia. 3. The pressor principle contained in ischemic renal perfusates is the cause of the hypertens...
