This review article looks at the emerging concepts about the renin angiotensin system. The specific aspects it covers include angiotensin II receptors, angiotensin receptor antagonists and alternative enzymatic pathways for the conversion of angiotensin I to angiotensin II other than angiotensin converting enzyme. The review, additionally, looks at the current and future clinical applications o...
The study of experimental hypertension and the development of drugs with selective inhibitory effects on the enzymes and receptors constituting the components of the circulating and tissue renin-angiotensin systems have led to newer concepts of how this system participates in both physiology and pathology. Over the last decade, a renewed emphasis on understanding the role of angiotensin-(1-7) a...
The renin-angiotensin-aldosterone system has been causally implicated in obesity-associated hypertension. We studied the influence of obesity and weight reduction on the circulating and adipose tissue renin-angiotensin-aldosterone system in menopausal women. Blood samples were analyzed for angiotensinogen, renin, aldosterone, angiotensin-converting enzyme activity, and angiotensin II. In adipos...
Levels of angiotensin II immunoreactivity in the rat adrenal gland are over one hundredfold higher than those in plasma. It is unclear, however, whether the major source of adrenal angiotensin II immunoreactivity is intracellular synthesis by a local renin-angiotensin system, uptake by angiotensin II receptors, or both. Our studies show that angiotensin II immunoreactivity in the adrenal gland ...
It has been established that deoxycorticosterone acetate (DOCA)-salt hypertensive rats have an overactive brain angiotensin-system. The purpose of the present study was to identify the brain sites showing enhanced angiotensin-system activity responsible for the pathogenesis of hypertension in DOCA-salt hypertensive rats. The angiotensin receptor antagonist, losartan, was injected into brain ven...
background: renal ischemia reperfusion (ir) injury has been a major source of concern during the past decades and angiotensin converting enzyme (ace) inhibitors have been successfully used to prevent this injury. there have been some controversial reports about the involvement of katp channels in the mechanism of action of ace inhibitors. in this study, we examined the effect of katp channel bl...
