    Amphetamines are well documented to produce paranoid psychotic episodes in individuals abusing chronically, or even taking large doses acutely (Chapman, viagra pfizer djelovanje 1953. Johnson and Milner, 1967. A possible understanding of how amphetamines produce paranoid ideation and psychosis extends from this analysis of actual overt motor effects to the actions of these drugs on cognitive function.

    Indeed, some aspects of the behavioral principle for stimulants outlined above, where the increasing rates of behavior combine with a decreasing number of response categories as outlined by Lyon and Robbins , can be considered a form of rate dependency. Clearly, in rodents with psychostimulants, as the dose increases, high rates of behavior in operant situations decrease and locomotor activity decreases, and head bobbing and other forms of stereotyped behavior that have an initial low frequency of behavior increase (Lyon and Robbins, 1972).

    Macrophages are long-lived and secrete numerous cytokines, enzymes, and enzyme inhibitors viagra pfizer djelovanje. Macrophages are larger than monocytes, and have an oval nucleus, prominent nucleoli, a blue cytoplasm, and phagocytic vesicles. Macrophages After several hours of transit in the blood, the monocytes migrate into different tissues, where they differentiate into macrophages. The nucleus is viagra pfizer djelovanje large and often indented with clumped chromatin.

    The different types of macrophages are known as components of the reticulo-endothelial system. Monocytes and macrophages can phagocytose pathogens, present antigens, and secrete many cytokines.

    These projections are hypothesized to act in parallel to facilitate the processing of information and also to interact with each other through viagra pfizer djelovanje feedback mechanisms (Le Moal and Simon, 1992. Le Moal, 1994. Even more intriguing are data showing that low levels of D4 receptors predict the rewarding effects of psychostimulants. However, rapid viagra pfizer djelovanje tolerance develops to this enhanced release, and acute withdrawal and protracted withdrawal are associated with decreases in dopamine D5 receptors for both drugs.

    The mesocortical dopamine circuits, again, largely based on work with psychostimulant drugs (e.g., mesoprefrontal, orbitofrontal, and mesoanterior cingulate cortices), have been associated with incentive salience, drug expectation, compulsive intake, loss of control, conscious experiences of drug intoxication, and craving. In animal studies, based largely on work with psychostimulant drugs, the mesolimbic dopamine circuits (i.e., mesoaccumbens and mesoamygdala) have been associated with the acute reinforcing effects of drugs and with the emotional and motivational changes associated with drug withdrawal. Acute administration of cocaine and alcohol has been shown to enhance dopamine release in the ventral striatum as measured by imaging studies.
