In vivo release of dopamine in the nucleus accumbens of the rat: modulation by cholecystokinin.
Mark M. Voigt,Rex Y. Wang +1 more
TLDR
It is observed that the release of endogenous dopamine, induced by perfusion of a 55 mM K+-containing buffer in the nucleus accumbens, was Ca2+-dependent and confined to a local region, and that the sulphated form of cholecystokinin octapeptide, but not the unsulphated form, suppressed this stimulated release of dopamine in a concentration-dependent manner.About:

Serotonin microinfusion into the ventral tegmental area increases accumbens dopamine release
TL;DR: The results suggest that 5-HT innervations in the VTA may have an excitatory action possibly via5-HT1B rather than 5- HT1A receptors on the mesolimbic DA system projecting to the ACC and that this DA system may also be regulated by glutamatergic and GABAergic inputs.

Cholecystokinin potentiates dopamine-mediated behaviors: evidence for modulation specific to a site of coexistence
TL;DR: CCK did not potentiate DA-induced hyperlocomotion or apomorphine-induced stereotypy when injected into the caudate nucleus, where CCK and DA are localized in separate neurons in rats.

Interactions of cholecystokinin octapeptide and dopamine on nucleus accumbens neurons.
Francis J. White,Rex Y. Wang +1 more
TL;DR: Local microiontophoretic administration of cholecystokinin octapeptide increased the firing rates of neurons in the dorsomedial nucleus accumbens (NAc), but exerted little to no effect on lateral NAc neurons.

Ventral mesencephalic neurons containing both cholecystokinin- and tyrosine hydroxylase-like immunoreactivities project to forebrain regions.
TL;DR: The coexistence of cholecystokinin‐ and tyrosine hydroxylase‐like immunoreactivities within neurons of the rat ventral mesencephalon was analyzed by using an indirect immunofluorescence technique for the simultaneous demonstration of two antigens in the same tissue section.

Dynamic response of chest wall and lung injuries in rabbits exposed to air shock waves of short duration.

TL;DR: The chest walls of rabbits exposed to steep-fronted air shock waves of short duration produced by 50 g spherical charges of TNT were recorded by means of a mechano-electric motion transducer to study the correlation between the deformations of the chest and the damage inflicted to the underlying organs, especially the lungs.
