PLASMA NOREPINEPHEINE AND DOPAMINE-BETA-HYDOROXYLASE ACTIVITY IN CHRONIC RENAL FAILURE

Plasma norepinephrine concentration and plasma dopamine-beta-hydroxylase activity in patients with congestive heart failure.

The relationship between plasma norepinephrine (NE), epinephrine (E) and dopamine-beta-hydroxylase activity (DBH) was studied in 90 cardiac patients (New York Heart Association [NYHA] classes I-IV), 85 healthy control subjects and 18 competitive skiers. The cardiac patients in NYHA classes III and IV had significantly higher NE (p less than 0.001) and lower DBH (p less than 0.001) levels than t...

Association of hemodialysis and pruritus in chronic renal failure

Background and aim: Pruritus is a common disabling problem in patients with end stage renal disease. Several studies has recorded the relation between pruritus with hemodialysis in chronic renal failure (CRF) patients. This study was designed to evaluate the effect of hemodialysis on pruritus of patients with CRF.Materials and Methods: After recording the demographic data and the diagnosis of d...

Etiology of Chronic Renal Failure in Children and Lnfants

Chronic renal failure is an uncommon disease in children with some difference in the etiology in different countries. In this study on 180 children (From 1987 to 1997 in Shiraz) with age range of 3 months to 15 years (mean 8.6±4.2 years). The male to female ratio was 1. 57: 1. The etiology of chronic renal failure in decreasing order of frequency were: reflux nephropathy (25 % ) , glbmerular di...

Plasma S-nitrosothiols and chronic renal failure.

Effect of imipramine treatment on plasma dopamine beta-hydroxylase activity in chronic mild stress in rats.

Dopamine beta-hydroxylase (DBH) which catalyzes conversion of dopamine into noradrenaline, may be a good blood marker of unipolar depression. Therefore, we studied the effect of classic antidepressant drug imipramine (10 mg/kg ip) on activity of this enzyme in plasma of rats subjected to chronic mild stress (CMS), the model of anhedonia. CMS induced reductions in DBH activity by the second day ...
