Objective: Acute ethanol intoxication has been shown to cause oxidative damage in many organ systems including the brain. Erythropoietin has antioxidant effects and prevents neuronal damage in the animal model of ischemic brain injury. In this study, we aimed to investigate the effects of darbepoetin alpha, an analog of erythropoietin with a longer half-life and higher in vivo activity, on ethanol-induced acute brain injury.
Methods: Forty-eight Wistar albino rats were allocated to four groups. The first group received ethanol treatment (E), the second group was treated with ethanol and darbepoetin (ED), the third group received only saline treatment (S), and the fourth group received both saline and darbepoetin treatment (SD). Plasma S100-β and neuron-specific enolase (NSE) levels were measured. Histopathological evaluation of the brains was performed.
Results: The plasma S100-β and NSE levels were significantly lower in group ED compared with group E. In group E, we have observed focal red-neuron formation at the granular layer of the dentate gyrus. We did not observe any histopathological changes in the other groups (ED, S, and SD).
Conclusion: Our findings suggest that darbepoetin alpha has neuroprotective effect in acute ethanol intoxication, possibly through its antioxidant effect.

Alcohol consumption is known to affect dopamine (DA) release in the brain, with significant implications for understanding addiction and its neurobiological underpinnings. This meta-analysis examined the effects of acute alcohol administration on striatal DA release in healthy humans as measured with [C]-raclopride positron emission tomography (PET). Oral alcohol administration was associated with a significant reduction in [C]-raclopride binding potential (BP) in the ventral striatum (Cohen's d = -0.

Muscle atrophy, an age-related condition, presents a growing healthcare concern within the context of global population aging. While studies have investigated for its potential antifatigue properties, reports on its active components remain limited. This study evaluated the efficacy of mycelium extract on muscle health, utilizing a 1:1 water-ethanol preparation administered to C57BL/6 mice exhibiting acute hind leg atrophy.

Individuals with prenatal alcohol exposure (PAE) are at a higher risk for developing alcohol use disorder (AUD). Using a rat model of moderate PAE (mPAE) on gestational day 12 (G12; ∼2 trimesters in humans), a critical period for amygdala development, we have shown disruptions in medial central amygdala (CeM) function, an important brain region associated with the development of AUD. In addition to this, acute ethanol (EtOH) increases GABA transmission in the CeM of rodents in a sex-dependent manner, a mechanism that potentially contributes to alcohol misuse.

We examined the number of patients tested for serum ethanol concentration (SEC) at admission to a large Emergency Department (ED) and the relationship of SEC with sex and age. SEC was analysed by enzymatic method. We retrieved SEC in patient samples from the ED during 2015-2020 from the laboratory information system.
