In this study, the changes of renin system activity and the effects of aspirin therapy on the plasma renin activity ( PRA) in myocardial infarction were investigated. Fifty nine patients with myocardial infarction were selected. By suppressed in the former group which was statistically significant ( p<0.01).   

The renin–angiotensin–aldosterone system is the well established endocrine system having significant role in preserving hemodynamic stability. Renin is secreted from the juxtaglomerular cells of the kidney. Phenylpiperazine derivatives have been reported as human renin inhibitor. To perform predictive QSAR modeling for 27 phenylpiperazine derivatives as renin enzyme inhibitors. The IC50 values ...

paraneoplastic syndromes result from secretion of hormones, peptides or cytokines by tumor or immune cross-reactivity between malignant and normal tissues. these conditions are rare in children, but when the clinical presentation of patients with a tumor is unusual, these syndromes should be emphasized . extrarenal tumors with renin-secretion are rare in children. they may be related to paraneo...

objective(s) we investigated the effects of low-dose morphine on nitric oxide (no) and angiogenesis in two-kidney one clip hypertensive (2k1c) rats. materials and methods male rats were divided into two groups: sham-clip operated and 2k1c. each group subdivided into saline and morphine (3 mg/kg i.p. 8 weeks) groups. blood pressure, heart rate, plasma renin activity (pra), no concentration and m...

three siblings (1 boy, 2 girls) with hypertension and hypokalemia are presented, two with low plasma aldosterone and suppressed renin activity and the eldest with a high renin and aldosterone level due to secondary changes in her kidneys. urinary tetrahydrocortisol (thf) was increased relative to tetrahydrocortisone (the). cortisol ring a reduction constant was also lower than normal. these fin...

The important renal endocrine aspect implicated in gym nephropathy is the activation of renin-angiotensin-aldosterone system (RAAS). Intense exercise can lead to increased sympathetic nervous activity, resulting release renin from juxtaglomerular cells kidneys. Renin acts on angiotensinogen, leading generation angiotensin II, a potent vasoconstrictor. Angiotensin II stimulates secretion aldoste...

Three siblings (1 boy, 2 girls) with hypertension and hypokalemia are presented, two with low plasma aldosterone and suppressed renin activity and the eldest with a high renin and aldosterone level due to secondary changes in her kidneys. Urinary tetrahydrocortisol (THF) was increased relative to tetrahydrocortisone (THE). Cortisol ring A reduction constant was also lower than normal. Thes...

To evaluate whether, in the forearm of hypertensive patients with different circulating renin profiles, local beta-adrenergic receptor-induced production of active renin, plasma renin activity, angiotensin I (Ang I), and angiotensin II (Ang II) was or was not related to the renin profile, we studied four groups of patients: 1) hypertensive patients with primary aldosteronism and suppressed circ...

Active, inactive and total plasma renin activity (obtained after cryoactivation), active, inactive and total plasma renin concentration (obtained after acid activation) and plasma angiotensin II were measured in 20 healthy infants and in 20 healthy adults. Active plasma renin activity but not active plasma renin concentration or plasma angiotensin II were significantly higher in the infants. In...
