Swimming exercise attenuates psychological dependence and voluntary methamphetamine consumption in methamphet- amine withdrawn rats
Objective(s): This study evaluated the effect of swimming exercise during spontaneous methamphetamine (METH) withdrawal on the anxiety, depression, obsessive-compulsive disorder (OCD) and voluntary METH consumption in METH-dependent rats. Materials and Methods: Male Wistar rats were repeatedly administered with bi-daily doses of METH (2 mg/kg, subcutaneous) over a period of 14 days. Exercised ...
متن کاملModulation of voluntary ethanol consumption by beta-arrestin 2.
Beta-arrestin 2 is a multifunctional key component of the G protein-coupled receptor complex and is involved in mu-opiate and dopamine D2 receptor signaling, both of which are thought to mediate the rewarding effects of ethanol consumption. We identified elevated expression of the beta-arrestin 2 gene (Arrb2) in the striatum and the hippocampus of ethanol-preferring AA rats compared to their no...
متن کاملEffect of swimming exercise on spatial learning and memory, and voluntary morphine consumption in maternally separated rats in adulthood
Introduction: Maternal separation (MS) can lead to learning and memory deficits, and also the risk of addiction. On the other hand, physical activities may lead to long-term changes in the mesolimbic dopamine pathway and the hippocampus. This study was designed to examine the effect of swimming exercise on the spatial learning and memory and voluntary morphine consumption in maternally separate...
متن کاملLong-lasting increase in voluntary ethanol consumption and transcriptional regulation in the rat brain after intermittent exposure to alcohol.
Prolonged exposure of the brain to ethanol is a prerequisite for developing ethanol dependence, but the underlying neural adaptations are unknown. Here we demonstrate that rats subjected to repeated cycles of intoxication and withdrawal develop a marked and long-lasting increase in voluntary ethanol intake. Exposure-induced but not spontaneous alcohol intake is antagonized by acamprosate, a com...
متن کاملDietarily-induced changes in voluntary ethanol consumption and ethanol metabolism in the rat.
1. The voluntary ethanol consumption, ethanol elimination rate and blood acetaldehyde level after intraperiotoneal injection of ethanol were studied in rats receiving diets with highly imbalanced proportions of dietary protein, carbohydrate and fat. 2. The rats, which received the low-protein diet containing 0.05 of the total energy as protein, 0.80 as carbohydrate and o.15 as fat, drank only a...
