The purpose of this study is to evaluate the effect of the bioconversion products of extract fermented by (OEFL) on relieving hangovers and improving liver function. In addition, the bioactive substance of the OEFL, which alleviates hangover and ethanol-induced liver damage, was identified and its bioactive property was verified through in vivo experiments. In major substances analysis using high-performance liquid chromatography, OEFL produced 9.5-fold higher -coumaric acid than the extract (OE). In addition, considering that quinic acid, which is not present in the OE, was produced in the OEFL it was confirmed that chlorogenic acid was decomposed into quinic acid by bioconversion. In the in vivo experiment using Sprague-Dawley rats, the OEFL and -coumaric acid diets reduced blood ethanol, acetaldehyde, GPT, and ALP concentrations, increasing blood albumin concentrations compared to ethanol-administered groups, demonstrating that OEFL and -coumaric acid, the main substance in the OEFL, improved ethanol-induced liver damage. Furthermore, the OEFL and its main bioactive substance, -coumaric acid, alleviated liver fibrosis by downregulating , and upregulating . Therefore, OEFL is expected to be used as a functional food or pharmaceutical material as it has been confirmed to effectively relieve hangovers, prevent liver damage, and delay liver fibrosis in ethanol-induced liver damages.

In this study, antiulcer activity of ethanolic extract and solvent fractions of the aerial part of was investigated using ethanol-induced model of gastric ulceration in rats. The results showed that ethyl acetate, non-polar components and diethyl ether fractions have a remarkable antiulcerogenic activity; because they exhibited control-ulcer protection by 85.2%, 77.

Article Synopsis
- The progression of Alcohol-associated liver disease (ALD) involves increased gut permeability due to ethanol, leading to bacterial products entering the bloodstream and causing liver inflammation and damage.
- The study used mice without the SIRT7 gene in myeloid cells, finding that this knockout reduced liver injury and inflammation caused by alcohol while minimally impacting lipid metabolism.
- Identification of CCL2 as a key target affected by SIRT7 highlights how its knockout hinders macrophage CCL2 secretion and monocyte recruitment, suggesting that targeting SIRT7 could provide new treatment strategies for ALD.

Objective: This study aimed to evaluate the severity of liver fibrosis in chronic liver disease patients using aspartate aminotransferase-to-platelet ratio index (APRI), fibrosis-4 (FIB-4), FibroScan, and the Child-Turcotte-Pugh (CTP) score. It emphasized assessing fibrosis progression toward cirrhosis (F4 stage) and exploring the correlation between non-invasive markers and the CTP score for liver function and prognosis.
Methodology: This observational cross-sectional study was conducted over one calendar year in the Department of Medicine at Baba Raghav Das (BRD) Medical College, Gorakhpur, India.

The study aimed to explore the protective impact of polysaccharide derived from (Turner) C. Agardh (SHP) against ethanol-induced injury in LO2 hepatocytes, along with its potential mechanism of action. A model of alcoholic injury in LO2 cells was established to assess the shielding effect of SHP against liver injury induced by alcohol.

Background And Aims: Alcohol-associated liver disease (ALD) is a leading cause of liver-related mortality worldwide, with limited treatment options beyond abstinence and liver transplantation. Chronic alcohol consumption has been linked to magnesium (Mg 2+ ) deficiency, which can influence liver disease progression. The mechanisms underlying Mg 2+ homeostasis dysregulation in ALD remain elusive.
