[3H]noradrenaline efflux from platelets and synaptosomes of ethanol-treated rats.
Platelets have the ability to take up, store and release biogenic amines and have therefore been used as models for neurons in studies of neuropsychiatric disorders and hypertension. We have studied the spontaneous efflux of [3H]noradrenaline from platelets and synaptosomes of rats chronically treated with ethanol. Male control rats had a more rapid [3H]noradrenaline efflux both from synaptosomes and platelets than female control rats. Ethanol treatment increased efflux in female rats, again both in platelets and synaptosomes. These results suggest that a parallelism exists in noradrenaline release between synaptosomes and platelets, both basal and in situations which stimulate the release.
