Serum angiotensin-converting enzyme activities were measured in 41 type 1 diabetics (16.4 +/- 4.0 U/ml), in 40 type 2 diabetics (15.0 +/- 5.2 U/ml) and in 52 controls (13.0 +/- 2.7 U/ml, mean +/- SD). Twenty six (32%) of 81 patients presented with serum angiotensin-converting enzyme activities above the normal range. No relation between serum angiotensin-converting enzyme activities and the pre...

Angiotensin-converting enzyme inhibitor was used in dogs with uranyl nitrate-induced acute renal failure to evaluate (1) a possible protective effect of angiotensin blockade and (2)the role of angiotensin II in the generation of renal failure in this model. Angiotensin-converting enzyme inhibitor treatment attenuated the fall in glomerular filtration rate and renal blood flow during the first 6...

The angiotensin-converting enzyme from rabbit lung was purified to a homogeneous protein. The molecular weight of the enzyme or its subunits in sodium dodecyl sulfate-polyacrylamide gel electrophoresis was established as 180,000. Converting enzyme contained about 8% (w/w) hexoses (based on glucose). The K,,, values for the hydrolysis of angiotensin I and [desAspllangiotensin I by the purified e...

According to the World Health Organization, infertility, associated with metabolic syndrome, has become a global issue with a 10%-20% incidence worldwide. An accumulating body of evidence has shown that the renin-angiotensin system is involved in the fertility problems observed in some populations. Moreover, alterations in the expression of angiotensin-converting enzyme-1, angiotensin-convertin...

Increased activity of the renin-angiotensin system has been implicated in decreased, long-term survival of renal allografts. Recent studies suggest that a deletion variant of the angiotensin-converting enzyme, associated with increased humoral and tissue activity of this enzyme, is a risk factor for the development of diabetic nephropathy and the progression of IgA nephropathy. To determine whe...

PURPOSE OF REVIEW Several trials demonstrated that angiotensin-converting enzyme inhibitors reduce the incidence of cardiovascular events during long-term follow-up in high-risk and low-risk patients. Clinical treatment guidelines propose that angiotensin-converting enzyme inhibitors should be considered in the routine secondary prevention in the broad group of coronary artery disease patients....

introduction: renin angiotensin system has an important role in blood pressure and renal functions. active angiotensin-converting enzyme 2 converts angiotensin i into angiotensin-(1-7) which is a vasodilator hormone and interacts with nitric oxide changes as well as other angiotensin ii receptors. in this study we evaluated the role of mas receptor antagonist (a779) and renal perfusion pressure...

Abstract Background African wild lettuce ( Lactuca taraxacifolia Willd.) is an underutilised indigenous leafy vegetable containing essential nutrients and medicinal properties. Hence, this study aimed to determine the chemical composition, antioxidant activities, α-amylase, α-glucosidase angiotensin converting enzyme inhibitory potentials of leaves powder samples. Methods Freshly harvested Wild...

Obstructive sleep apnea is associated with hypertension and cardiovascular disease. Chronic intermittent hypoxia is used to model the arterial hypoxemia seen in sleep apnea patients and is associated with increased sympathetic nerve activity and a sustained diurnal increase in blood pressure. The renin angiotensin system has been associated with hypertension seen in chronic intermittent hypoxia...
