Platelet intracellular free calcium concentration was assessed by the quin-2 method in 38 patients with essential hypertension and in 35 normotensive subjects. The concentrations were found to be… (More)
The acute effects of nifedipine (20 mg sublingually) and of captopril (12.5 mg orally) on blood pressure and on platelet intracellular free calcium were investigated in 11 and 12 patients,… (More)
Our study on intracellular effects of angiotensin II in human platelets showed that: (1) angiotensin II increases intracellular free calcium in platelets via a receptor-operated mechanism and this… (More)
To gain insight into the role of the sympathetic nervous system in the development of mineralocorticoid hypertension, we determined noradrenaline and adrenaline in plasma and urine before, during and… (More)
Intracellular free calcium is considered to play a key role in vascular smooth muscle contraction. Platelet-free intracellular and plasma total and ionized calcium were assessed during… (More)
The effects of acute hypermagnesaemia on intracellular free calcium and adrenergic activity were investigated in six normotensive volunteers given intravenous magnesium sulphate for 3 h. The free… (More)
