Calcium influx plays important roles in the pathophysiology of seizures, including acoustically evoked alcohol withdrawal-induced seizures (AWSs). One Ca influx route of interest is the Na/Ca exchanger (NCX) that, when operating in its reverse mode (NCX) activity, can facilitate Ca entry into neurons, possibly increasing neuronal excitability that leads to enhanced seizure susceptibility. Here, we probed the involvement of NCX activity on AWS susceptibility by quantifying the effects of SN-6 and KB-R7943, potent blockers of isoform type 1 (NCX1) and 3 (NCX3), respectively. Male, adult Sprague-Dawley rats were used. Acoustically evoked AWSs consisted of wild running seizures (WRSs) that evolved into generalized tonic-clonic seizures (GTCSs). Quantification shows that acute SN-6 treatment at a relatively low dose suppressed the occurrence of the GTCSs (but not WRSs) component of AWSs and markedly reduced the seizure severity. However, administration of KB-R7943 at a relatively high dose only reduced the incidence of GTCSs. These findings demonstrate that inhibition of NCX1 activity is a putative mechanism for the suppression of alcohol withdrawal-induced GTCSs.

The N-methyl-D-aspartate (NMDA) glutamate receptor is a major target of ethanol, and it is implicated in learning and memory formation, and other cognitive functions. Glycine acts as a co-agonist for this receptor. We examined whether Org24598, a selective inhibitor of glycine transporter1 (GlyT1), affects ethanol withdrawal-induced deficits in recognition memory (Novel Object Recognition (NOR) task) and spatial memory (Barnes Maze (BM) task) in rats, and whether the NMDA receptor glycine site participates in this phenomenon.

Introduction: Substance use disorders, particularly alcohol use disorders, represent a significant public health problem, with adolescents particularly vulnerable to their adverse effects. This study examined the possible anxiolytic and antidepressant effects of biotin, a crucial vitamin for brain function, in attenuating the behavioral and neurobiological changes associated with alcohol withdrawal in adolescent rats.
Materials And Methods: Sixty male Sprague-Dawley rats were exposed to a 20% ethanol solution for 21 days, followed by a 21-day drug-free period to assess long-term behavioral and physiological changes.

Purpose: Regarding a wide variety of researches conducted with various therapeutic effect of crocin, the main constituent of saffron, the current study aims to assess the efficacy of crocin to improve learning and memory impairment caused by withdrawal following concurrent usage of ethanol (Eth) and nicotine (Nic) in adolescent male rats.
Methods: In order to test memory fucntion, Morris water maze and passive avoidance methods were applied in male Wistar rats undergone adolescent Nic-Eth withdrawal and the effect of crocin treatment was assessed at both behavioral and biochemical levels. The biochemical parameters included the inflammatory cytokines, indicators of oxidative stress and cholinergic metabolism within the hippocampla tissues.
Alcohol use disorder (AUD) is highly prevalent and associated with substantial morbidity and high mortality among substance use disorders. While there are currently three FDA-approved medications for treating AUDs, none specifically target the withdrawal/negative affect stage of AUD, underscoring the need to understand the underlying neurobiology during this critical stage of the addiction cycle. One key region involved in alcohol withdrawal and negative affect is the prelimbic cortex, a subregion of the medial prefrontal cortex.

Background: Pneumonia is a well-known complication in patients with severe alcohol withdrawal syndrome (SAWS). Antibiotic prophylaxis in ICU treated SAWS patients may be beneficial but data is lacking. The aims of this study were to investigate the effect of introduction of trimethoprim-sulfamethoxazole (TMP-SMX) prophylaxis, on use of broad-spectrum antibiotics and ICU length of stay (LOS) in SAWS patients with refractory delirium tremens (rDT).
