The effect of ouabain and dihydroouabain on Na+‐K+ ATPase, 86Rb uptake and the
release of [14C] ACh (acetylcholine) from synaptosomal preparations of guinea pigs was …

The relationship between 86Rb+ distribution across synaptosomal membrane and [14C]
acetylcholine (ACh) release have been studied in a rat brain cortex synaptosomal …

METHODS Synaptosomes were prepared from cerebral cortex of Sprague-Dawley rats by
the method of GRAY and WHITTAKER (1962) with modifications as described by …

Ouabain (5 X 10− 8‐5 X 10− 4 M) was confirmed to cause a dose‐dependent increase in
[3H] acetylcholine (pHJACh) release, cytosolic free Ca2+ concentration ([Ca2+] i), and …

Evidence that acetylcholine is an important neurotransmitter not only in the peripheral but
also in the central nervous system has been accunmlated by many investigators. It is also …

Synaptosomes took up [14C] choline, about half or more of which was converted to [I4C]
acetylcholine when incubated in an appropriate medium containing 1 to 5 μM‐[14C] choline …

Chemiluminescent detection was applied to measure the continuous spontaneous Ca2+‐
independent liberation of acetylcholine (ACh) from Torpedo electric organ synaptosomes …

WHEN brain tissue is homogenised in iso-osmotic sucrose the presynaptic nerve terminals
are detached and may be isolated as discrete particles (synaptosomes) by differential and …

1. The exchangeability with added radioactive acetylcholine of the acetylcholine in isolated
presynaptic nerve terminals (synaptosomes) and isolated synaptic vesicles was studied by a …

An increasing number of reports indicate that adenosine or related compounds may function
as mod~ ilators in the central nervous system. Thus, it has been shown that adenosine …
