Acupuncture as a therapeutic intervention has been used for the treatment of many functional disorders including substance abuse. However, there are still many unanswered question about the basic mechanism underlying acupuncture's effectiveness in the treatment of drug addiction. Repeated injection of psycostimulants or morphine can produce behavioral and(More)
The noradrenergic projections from brainstem nucleus tractus solitarius (NTS) to hypothalamic paraventricular nucleus (PVN) and amygdala (AMYG) are involved in nicotine-related stress responses and drug craving. Previous studies demonstrated that i.v. nicotine-induced norepinephrine (NE) release in the PVN and AMYG depends on nicotinic cholinergic receptors(More)
Oxytocin neurons represent one of the major subsets of neurons in the paraventricular hypothalamus (PVH), a critical brain region for energy homeostasis. Despite substantial evidence supporting a role of oxytocin in body weight regulation, it remains controversial whether oxytocin neurons directly regulate body weight homeostasis, feeding or energy(More)
In a previous study, acupuncture at acupoint HT7 attenuated ethanol withdrawal-induced anxiety-like behavior in rats by normalizing amygdaloid catecholamines. In the present study, the involvement of amygdaloid corticotropin-releasing factor (CRF) in the anxiolytic effect of acupuncture was investigated during ethanol withdrawal. Rats were intraperitoneally(More)
Orphanin FQ/nociceptin (NOC) has been reported to regulate dopaminergic neurotransmission in rewarding pathway, and to suppress the development of conditioned place preference (CPP) induced by certain addictive drugs. In this study, we investigated the effect of NOC on CPP induced by repeated administration of methamphetamine (MAP) in rats. Repeated(More)
1. The mechanism of stimulation of noradrenaline (NA) release by nicotine (NIC) was investigated in human cerebral cortex slices preloaded with 3H-noradrenaline. 2 NIC (10-1000 micro M) increased 3H-NA release in a concentration-dependent manner. 3. NIC (100 micro M)-evoked 3H-NA release was largely dependent on external Ca2+, and was attenuated by(More)
BACKGROUND Korean Red Ginseng (KRG) is known to have antianxiety properties. This study was conducted to investigate the anxiolytic effects of KRG extract (KRGE) during ethanol withdrawal (EW) and the involvement of the mesoamygdaloid dopamine (DA) system in it. METHODS Rats were treated with 3 g/kg/d of ethanol for 28 d, and subjected to 3 d of(More)
The current study investigated the effects of acupuncture at Zu-San-Li (ST36) on the hypothalamic-pituitary-adrenal axis during ethanol withdrawal in rats. Rats were intraperitoneally treated with 3 g/kg/day of ethanol or saline for 28 days. Following 24 hours of ethanol withdrawal, acupuncture was applied at bilateral ST36 points or non-acupoints (tail)(More)
This study investigated the involvement of the mesolimbic dopamine (DA) system in the anxiolytic effects of acupuncture during ethanol withdrawal (EW). Rats were intraperitoneally treated with 3g/kg/day of ethanol for 28 days and experienced 3 days of withdrawal. During EW, the rats were bilaterally treated with acupuncture at acupoints HT7 (Shenmen) or PC6(More)
Glycyrrhizae Radix modulates the neurochemical and locomotor alterations induced by acute psychostimulants in rodents via GABAb receptors. This study investigated the influence of methanol extract from Glycyrrhizae Radix (MEGR) on repeated methamphetamine- (METH-) induced locomotor sensitization and conditioned place preference (CPP). A cohort of rats was(More)
