EDITORIAL REVIEWCombining renin-angiotensin-aldosterone system blockade with diuretic therapy for treatment of hypertension
Moreover, ongoing research suggests that this new class of drugs may be an important approach, not only for the treatment of hypertension and of conditions associated with overt volume overload but also for ischaemic heart disease.
Objectives: Systemic infusions of aldosterone cause an acute increase in systemic vascular resistance (SVR) in healthy subjects.

 HDCN-- AII Receptor Symposium at ASH 96: Presentation of Dr. de Zeeuw
Now it is clear that if we intervene in the renin angiotensin system, and there have been many studies that have been demonstrating that elegantly...
I think that at this time point the hypothesis is valid to put forward to state that these hemodynamic changes on the one hand, induced by the renin angiotensin system, are the working hypothesis of angiotensin II and its role in maybe decline of function of organs.
So it looks like that with the ACE inhibitors we have drugs intervening in the renin angiotensin system differentiating themselves from not only reducing the blood pressure effectively but also changing the renal hemodynamics, possibly lowering inter-glomerular pressure and, on the other hand, lowering proteinuria.

Activation of local renin-angiotensin system by chronic hypoxia in rat pancreas.
Although we originally measured significant angiotensin-(1-7) levels in the dog pancreas, whether this peptide influences pancreatic function is also unknown.

 Journal of the Renin-Angiotensin-Aldosterone System : Welcome
As a result of these studies, research in the laboratory and clinic is rapidly exploring the significance of these systems in cardiovascular and non-cardiovascular diseases.
In the last decade the renin-angiotensin-aldosterone system (RAAS) and other peptidergic systems, such as atrial natriuretic peptides and endothelin, have become an increasingly important focus of basic cardiovascular research.
Results of clinical trials of drugs inhibiting the systems in the treatment of hypertension, renal disease, heart failure, post-myocardial infarction and diabetes as well as new areas of clinical research into the possible value of these agents in new indications such as maintenance of cognitive function

 Renin-angiotensin system - Wikipedia, the free encyclopedia
The renin-angiotensin system is often manipulated clinically to treat high blood pressure.
The system can be activated when there is a loss of blood volume or a drop in blood pressure (such as in a hemorrhage).
As with most other capillary beds in the body, the constriction of afferent arterioles increases the arterioler resistance, raising systemic arterial blood pressure and decreasing the blood flow.

Additional long-term controlled clinical trials are needed to clarify the benefits and risks of cardiovascular outcomes associated with blood pressure reduction induced by antihypertensive agents that antagonize components of the renin-angiotensin-aldosterone system in patients with multiple cardiovascular risk factors.

 Diabetes Care: Renin-Angiotensin System Gene Polymorphisms, Bl... @ HighBeam Research
The renin-angiotensin system (RAS) helps maintain blood pressure and salt homeostasis and may play a role in the pathogenesis of aspects of the metabolic syndrome.
However, like other public hospitals in Hong Kong, because the system of government-funded primary care is not developed to the same extent as in most Western countries, many of the patients attending the clinics use the facility as their only source of subsidized medical care for management of their chronic diseases.
The patients involved therefore do not represent a highly selected group of the most severe cases, but are a typical cross-section of patients with these conditions from this region of Hong Kong.

 The renin-angiotensin system and atherosclerosis
Therefore, today we have asked Dr. Hiromi Rakugi, of the Department of Geriatric Medicine, Osaka University Medical School to discuss the renin-antiotensin system and atherosclerosis.
Since atherosclerosis, especially that in the coronary and cerebral blood vessels, is a direct cause of death, the prevention of atherosclerosis caused by hypertension is an important topic with repect to patient prognosis.
AII increases insulin resistance by two mechanismus: a) reduction of blood flow in muscle tissue by increasing peripheral vascular resistance; and b) activation of the sympathetic nervous system.

 Genetic Diversity Of Renin-Angiotensin System
Faster progression to ESRD is associated (a) with the ACE genotype in all the patients with ESRD and (b) with the AGT genotype in patients with glomerulonephritis.
Comments: All patients of diabetes mellitus do not develop nephropathy.
With the help of this type of information, one can be more aggressive in management of other modifiable risk factors for development of diabetic nephropathy and progression of ESRD in patients who have genetic predisposition to development and faster progression to ESRD.

 Renin Angiotensin Ssystem
Angiotensin II is both a vasoconstrictor and the most important stimulus for the release of aldosterone by the adrenal cortex.
The enzyme, renin, is secreted by the kidney in response to decreased renal perfusion pressure or flow; it cleaves the decapeptide angiotensin I from angiotensinogen.
The latter two are useful agents in treatment of hypertension and heart failure though have differences in action: ACEIs also block kinin production while A-IIRAs are specific for the AT-II receptor.

Renin is a proteolytic enzyme produced by the juxtaglomerular apparatus that converts angiotensinogen in the blood to angiotensin I. Renin release is under the control of a number of factors including blood pressure and volume, and urinary composition.

 Upregulation of renal renin-angiotensin system in mouse diabetic nephropathy : HUSCAP
The aim of this study was to clarify the role of the renal renin-angiotensin system (RAS) in diabetic nephropathy (DN), which was induced by injection of streptozotocin (STZ).
angiotensin type 1 (Agtr1) and type 2 (Agtr2) receptors in experimental DN, we performed laser-microdissection (LMD) followed by reverse transcriptase nested polymerase chain reaction using each specific primer pairs and immunohistochemistry for renin and angiotensin II.
CBA/N mice had a higher response after injection of STZ than CBA/J mice, showing a significant increase of the kidney/body weight ratio, although there was no significant difference between the two strains for the blood glucose level or pancreatic β-cell response...

 Renin-Angiotensin system during acute hypoxia
Acute hypoxia induces a decrease in plasma renin activity (PRA), mediated, e.g., by an increase in adenosine concentration, calcium channel activity, or inhibition of ATP-sensitive potassium channels.
This study investigates whether these hypoxia-induced mechanisms can be inhibited by the L-type voltage-dependent calcium channel antagonist nifedipine.
