The effect of acupuncture stimulation on alleviating emotional changes due to acute alcohol administration and the possibility of sigma1 receptor involvement.


ABSTRACT:

Background

Most ETOH addiction preclinical studies have focused on the rewards of chronic ETOH self-administration or the ETOH reinstatement model. Acute ETOH administration studies are scarce despite the potential of ETOH to cause sedation, intoxication and reduced acute functional tolerance. Here, we established a rat model of acute ETOH administration induced by an intraperitoneal injection of 1?g/kg ethanol and assessed the similarities in physiological and behavioral effects between acupuncture and Sigma1 R antagonists.

Methods

Male Wistar rats (300-330?g) received pretreatment with (1) saline injection, (2) saline?+?mechanical stimulation using a mechanical acupuncture instrument (MAI) for acupuncture at the Shenmen (HT7), (3) ETOH (1?g/kg) injection, (4) ETOH?+?HT7, or (5) the selective ?1 R antagonist BD 1047 (3, 10, or 30?mg/kg, intraperitoneal (IP) injection). ETOH (1?g/kg) or saline was IP injected after 10?min. Then, ETOH-induced immobility was evaluated in an open field arena, ultrasonic vocalizations (USVs) indicating ethanol-induced emotional changes were recorded in a recording chamber, and the rats were sacrificed for the analysis of protein levels of ?1 R in several regions of the brain.

Results

Acute ethanol exposure increased the immobile time, 22-kHz USVs, and protein levels of ?1 R in the ventral tegmental area (VTA). However, pretreatment with acupuncture at HT7 induced recovery of immobile time, reduced 22-kHz USVs, and regulated the protein levels of ?1 R in the VTA. These effects have similarities with IP injection of BD 1047 (10?mg/kg).

Conclusion

This study showed that acupuncture at HT7 regulates immobility and 22-kHz USVs via Sigma1 R in the VTA upon acute ETOH exposure.
