[Plasma dopamine concentrations in various types of hypertension].

The concentrations of unconjugated plasma dopamine (PDA) were studied in patients with various types of hypertension. Catecholamines were extracted from plasma specimens (1.0-3.0 ml) through an Amberlite CG50 (Li+-form) microcolumn and eluted by a magnesium sulfate - ethanol solution. The elute was then desalinated and deproteinized by the ethanol-treated precipitation procedure and dried in a ...

Plasma kinin concentration in deoxycorticosterone-salt hypertension.

We investigated the status of circulating kinins in rats with severe hypertension caused by drinking 1% NaCl (saline) and treatment with deoxycorticosterone (DOC, 25 mg/kg/wk s.c.) for 5 weeks. Saline-drinking rats treated with DOC had a higher systolic blood pressure (210 +/- 4 mm Hg) than did rats without DOC treatment drinking water (138 +/- 3 mm Hg) or saline (141 +/- 3 mm Hg). The concentr...

Effects of slow and rapid cooling on catecholamine concentration in arterial plasma and the skin.

Norepinephrine (NE) and epinephrine (Epi) concentrations in arterial plasma and in skin tissue were measured chromatographically before and after external cooling. Urethan-anesthetized rats were cooled either slowly (0.004-0.006°C/s) or rapidly (0.03- 0.05°C/s). Blood samples were drawn three times from each animal: 1) before cooling and at a rectal temperature decreased 2) by 0.5°C and 3) by 3...

Plasma Catecholamine Modulation

We measured a2-adrenoreceptor density as well as affinity for and sensitivity to agonist on intact platelets of normotensive and hypertensive subjects before and after physiological increases in plasma catecholamines. In normotensives, posture-induced rises in plasma catecholamines correlated with reduced C2-adrenoreceptor agonist affinity and fewer high affinity state receptors. Platelet aggre...

An experimental knee joint effusion does not affect plasma catecholamine concentration in humans.

Knee joint effusion causes quadriceps inhibition and is accompanied by increased soleus muscle excitability. In order to reverse the neurological alterations that occur to the musculature following effusion, we need to understand the extent of neural involvement. Ten healthy adults were tested on two occasions; during one session, subjects had their knees injected with saline and in the other a...
