2005 | Kim [40] | To investigate the effects of acupuncture on alcohol withdrawal syndrome (AWS) and Fos-like immunoreactivity (FLI) in the striatum and the nucleus accumbens (NAC) of rats | 24 Male Sprague–Dawley rats | Acupuncture at Zusanli (ST36) and Sanyinjiao (SP6) for 3 days | Alcohol withdrawal syndrome (AWS) and Fos-like immunoreactivity (FLI) in the striatum and the nucleus accumbens (NAC) | acupuncture was useful in the treatment of alcoholism by modulating post-synaptic neural activation in the striatum and NAC |
2006 | Yoshimoto [85] | To investigate the neuropharmacological mechanisms of oriental acupuncture | 24 Male Sprague–Dawley rats, n = 16 acupuncture | unilateral or bilateral acupuncture at Shenshu (BU23) acupoint, 60 min | Dopamine (DA) and serotonin (5-HT) contents of the microdialysates in the ACC | Acupuncture was effective for treatment of emotional disorders and laconism by increasing and prolonging the activity of serotonergic neurons |
2006 | Zhao [89] | To investigate the effects of acupuncture on chronic ethanol-induced changes in extracellular dopamine levels in the nucleus accumbens shell | 35 Male Sprague–Dawley rats, n = 21 sham or real acupuncture | Bilateral acupuncture at Shenmen (HT7) point or Neiguan (PC6) or tail) for 1 min | Extracellular dopamine levels in the nucleus accumbens shell (using in vivo microdialysis in unanesthetized rats) | Acupuncture at HT7 was effective to normalize the release of dopamine in the mesolimbic system following chronic ethanol treatment |
2007 | Kunz [43] | To compare auricular needle acupuncture with aromatherapy in reducing the duration and severity of symptoms of alcohol withdrawal with carbamazepine, oxcarbazepine, and benzodiazepines | 74 alcoholics, n = 36 acupuncture, n = 38 aromatherapy | AA at 5 NADA points, 45 min for 5 days | Alcohol-withdrawal syndrome (AWS scale), subjective visual analog scale of craving and the Self-Assessment Manikin (SAM) | acupuncture was not more effective than the control therapy on alcohol withdrawal symptoms |
2008 | Overstreet [64] | To investigate the EA effects for reducing voluntary alcohol intake in alcohol-preferring rats | 18 inbred alcohol-preferring P rats (IP), n = 9 EA | 2 and 100 Hz EA at Zusanli (ST36) and Sanyinjiao (SP6) for 30 min | Alcohol intake | Acupuncture affected on alcohol intake in the alcohol-dependent IP rats |
2009 | Dos Santos [28] | To investigate the effects of EA over locomotor sensitization induced by ethanol in mice | 12 Male Swiss mice | 2Â Hz EA at Zusanli (ST36) and/or Neiguan (PC6) for 10Â min | The locomotor activity, the expression of homer1A mRNA assessed by PCR | EA modulated homer1A expression and glutamatergic plasticity |
2010 | Yang [82] | To evaluate the effects of HT7 acupuncture on VTA GABA neuron excitability, ethanol inhibition of VTA GABA neuron firing rate, and ethanol self-administration | 32 Male Wistar rats | 2Â Hz EA at Shenmen (HT7) or Neiguan (PC6) for 1Â min | Ethanol-Reinforced Responding, VTA GABA Neuron Activity, VTA GABA Neuron Firing Rate | acupuncture reduced ethanol suppression of VTA GABA neuron firing rate, and reduced ethanol self-administration without affecting sucrose consumption |
2011 | Li [50] | To demonstrate that SD rats escalated their ethanol intake and subsequently developed ethanol dependence under the IE procedure | 26 Male Sprague–Dawley rats | 2 and 100 HZ EA at Zusanli (ST36) for 20 min | Intake of and preference for ethanol | EA treatments decreased the intake of and preference for ethanol, without resulting in a rebound increase in ethanol intake when the EA treatments were terminated |
2012 | Li [49] | To test the hypothesis that EA suppression on alcohol consumption may be mediated by transcription factors, such as FosB/ΔFosB protein in reward-related brain regions | 33 Male Sprague–Dawley rats | 2 and 100 HZ EA at Zusanli (ST36), 30 min for 6 days | The expression of FosB/ΔFosB in several reward-related brain regions using immunohistochemistry | EA treatment effectively reduced ethanol consumption and preference in rats by down-regulation of FosB/ΔFosB in reward-related brain regions |
2012 | Escosteguy-Neto [29] | To investigate EA effects during ethanol withdrawal on CB1R immunoreactivity | 12 Male Swiss mice | 2 and 100Â Hz EA at Zusanli (ST36)/Neiguan (PC6) or Dazhui (DU14)/Baihui (DU20), 10Â min for 4Â days | CB1R in the prefrontal cortex, striatum, hippocampus, amygdala and ventral tegmental area | EA inhibited CB1R upregulation which depended on acupoints association and frequency of stimulation |
2012 | Fallopa [30] | To investigate whether EA reverses locomotor sensitization induced by ethanol is parallel to ERK signaling | 12 Male Swiss mice | 2 and 100Â Hz EA at Zusanli (ST36)/Neiguan (PC6) or Dazhui (DU14)/Baihui (DU20), 10Â min for 4Â days | pERK immune-histochemistry | EA increased CB1R in the prefrontal cortex, striatum, hippocampus, amygdala and ventral tegmental area |
