Abstract:
Acute alcohol intoxication is a harmful clinical condition characterized by behavioral and neurological symptoms, for which few effective therapies are available at present. Dysfunction of microglial BV-2 cells has been reported to be associated with acute alcohol-induced brain injuries. In the present study, the protective effects of Eucommia ulmoides Oliv. leaves polysaccharides (EULP) on acute alcoholic brain injury and microglial dysfunction were investigated. 14-day pretreatment of EULP significantly attenuated neurobehavioral deficit and neurotransmitter damage in the brain tissue of mice caused by acute alcohol exposure. Additionally, EULP regulated the metabolic disorder of brain tissue. Consistently, it was shown that EULP pretreatment significantly improved alcohol-induced phagocytosis decrease, oxidative stress and inflammation in BV-2 cells. Therefore, EULP may be proposed and employed as a potential therapeutic agent for alcohol-induced brain damage.
