Interactions between social stress and morphine in the periaqueductal gray: effects on affective vocal and reflexive pain responses in rats.

abstract：RATIONALE:Chronic nicotine administration decreases the functioning of the cystine-glutamate antiporter system x(c)- which is hypothesized to promote nicotine-taking and nicotine-seeking behaviors. N-acetylcysteine (NAC), a cystine pro-drug, increases the activity of the cystine-glutamate antiporter system x(c)-. Thus,...
