Abstract
Platelets have been used as a model of sympathetic neurons to study the storage of nor-adrenaline in normotensive individuals belonging to families with essential hypertension for at least two generations. The efflux and initial efflux rate (K) of noradrenaline was determined in 36 young relatives (mean age 29.2 years) and in 20 young controls with no family history of hypertension (mean age 26.5 years). From the groups of relatives all those with definite hypertension had been excluded. Efflux and efflux rate K was significantly higher in young relatives (50.82 +/- 3.84 and 28.2 +/- 6.3) than in the controls (39.2 +/- 0.71 and 15.2 +/- 4.8). Of the relatives 25.2% had higher K values than any of the controls.
