Consumption of high doses of ethanol can lead to amnesia, which often manifests as a blackout. This incoordination of blackout may be a major cause in various social problems in alcohol consumption. However, there is still no treatment for preventing these alcohol-induced problems. Hydrangeae dulcis folium is a drug or a tea which is made from the fermented and dried leaves of Hydrangea serrata Seringe. The present study, we tested the ethanol extract of the Hydrangeae dulcis folium (EHDF) on ethanol-induced psychological deficits. To test behavioral deficits, an object recognition test was conducted using a mouse model. To evaluate synaptic deficits, N-methyl-D-aspartate (NMDA) receptor-mediated excitatory postsynaptic potential EPSP and long-term potentiation (LTP) in the mouse hippocampal slices were tested, as they are known to be vulnerable to ethanol and are associated with ethanol-induced amnesia. In the tests, ethanol (1 g/kg, i.p.) impaired object recognition memory, but EHDF (10 or 30 mg/kg) prevented this impairment in object recognition test. Interestingly, EHDF (30 μg/ml) significantly ameliorated ethanol-induced LTP and NMDA receptor-mediated synaptic transmission in the hippocampal slices. EHDF prevented ethanol-induced object recognition memory deficits induced by ethanol. Interestingly, EHDF significantly ameliorated ethanol-induced LTP and NMDA receptor- mediated synaptic transmission in the hippocampal slices.
