Background and Objectives: Previous observational studies presented a positive association between alcohol and atrial fibrillation (AF). However, previous studies using genetic polymorphisms on the causal relationship between alcohol consumption and AF have reported conflicting results. This study aimed to evaluate the causality between alcohol consumption and AF using the aldehyde dehydrogenase 2 (ALDH2) rs671 polymorphism, which is the genetic variant with the most potent effect on drinking behavior. Methods: A total of 8,964 participants from the Dong-gu Study were included in the present study. The causal association between alcohol consumption and AF was evaluated through a Mendelian randomization (MR) analysis using the ALDH2 rs671 polymorphism as an instrumental variable. Results: No significant relationship between alcohol consumption and AF was found in the observational analysis. However, the genetic analysis using the ALDH2 polymorphism showed a significant association in men. In the MR analysis, genetically predicted daily alcohol consumption was positively related to AF. Conclusions: MR analysis revealed a significant association between the amount of alcohol consumption and AF, which suggests that the association may be causal.

Recently, much attention has been paid to developing various kinds of fermented herbal extracts, a new type of traditional herbal medicine, in the field of Korean traditional medicine. The fermentation of medicinal herbs is intended to exert a favorable influence on digestability, bioavailavility and pharmacological activity of herbal extract in the gastrointestinal tract. It also produces a number of fermentation products that intensify the nutritional and pharmacological aspects of the medicinal herbs. In order to develop a functional beverage of alleviating the aftereffects of the previous drinks, the extracts (HP-1) of fermented herbal mixture, including Artemisia capillaris Thunb., Lonicera japonica Thunberg, and Hovenia dulcis Thunb., were prepared and the medicinal effect as a hangover cure was evaluated in ethanol-loaded rats. The enzyme activities of alcohol dehydrogenase (ADH) and acetaldehyde dehydrogenase-2 (ALDH2) were analyzed by measuring the concentration of blood ethanol and acetaldehyde. The mRNA expression of ADH and ALDH2 was also investigated through RT-PCR analysis. In the HP-1-treated group, the concentration of blood ethanol was significantly reduced at one hour after loading of ethanol, as compared to that in the saline-treated group. The reduced ethanol was converted to acetaldehyde, which resulted in rapid increase in acetaldehyde concentration in an hour. Acetaldehyde was started to decrease at 5 hours after ethanol loading. It implies that HP-1 is highly effective to stimulate the activities of ADH and ALDH2. The HP-1 treatment also activated the mRNA expression of ADH and ALDH. This study suggests that fermented herbal extract, HP-1 can be used as a functional beverage of alleviating the alcohol-induced hangover symptoms by stimulating the activities and gene expression of hepatic alcohol metabolizing enzymes.

The cricket has been used in East Asia as crude drugs for treating fever and hypertension, and is presently reared as a pharmaceutical insect in China and a food for animals. For the purpose of evaluating protective extracts against alcohol-induced toxicity, the extracts of the cricket (Gryllus bimaculatus) were examined in animal models acutely administered alcohol by the cricket in ICR-mice. Water and methanol extracts from the cricket, were found to cause a significant decrease (37%) in the blood ethanol concentration as well as enhancement of liver mitochondrial alcohol dehydogenase (ADH) and acetaldehyde dehydogenase (ALDH) activitieson on a single intraperitoneal administration in mice. Futhermore methanol extract was demonstrated to exhibit more potent enhancing activity on ethanol metabolism than water extract. These results suggest that water/alcohol extract of G. bimaculatus may be used as a food for reducing the toxicity of alcohol.

Hereditary spastic paraplegia is a not common inherited neurological disorder with heterogeneous clinical expressions. ALDH18A1 (located on 10q24.1) gene-related spastic paraplegias (SPG9A and SPG9B) are rare metabolic disorders caused by dominant and recessive mutations that have been found recently. Autosomal recessive hereditary spastic paraplegia is a common and clinical type of familial spastic paraplegia linked to the SPG11 locus (locates on 15q21.1). There are different symptoms of spastic paraplegia, such as muscle atrophy, moderate mental retardation, short stature, balance problem, and lower limb weakness. Our first proband involves a 45 years old man and our second proband involves a 20 years old woman both are affected by spastic paraplegia disease. Genomic DNA was extracted from the peripheral blood of the patients, their parents, and their siblings using a filter-based methodology and quantified and used for molecular analysis and sequencing. Sequencing libraries were generated using Agilent SureSelect Human All ExonV7 kit, and the qualified libraries are fed into NovaSeq 6000 Illumina sequencers. Sanger sequencing was performed by an ABI prism 3730 sequencer. Here, for the first time, we report two cases, the first one which contains likely pathogenic NM_002860: c.475C>T: p.R159X mutation of the ALDH18A1 and the second one has likely pathogenic NM_001160227.2: c.5454dupA: p.Glu1819Argfs Ter11 mutation of the SPG11 gene and also was identified by the whole-exome sequencing and confirmed by Sanger sequencing. Our aim with this study was to confirm that these two novel variants are direct causes of spastic paraplegia.

Cordyceps militaris L. (C. militaris) has been traditionally used as tonic medicine for metabolic syndrome. Cordycepin, has been reported with immunomodulatory, antitumor, and hepatoprotective effect, is the main extract from C. militaris. This study was conducted to evaluate the alcohol degradation and hepatoprotective effect of cordycepin-enriched C. militaris extract (CM) powder in chronic and binge ethanol (ethanol Lieber-DeCarli diet)-fed male C57BL/6 Mice. Cordycepin-enriched C. militaris extract powder was orally administered once daily at dose levels of 0, 125, 250, and 500 mg·kg^-1·day^-1 for 16 days. For evaluating alcohol degradation, ethanol concentration and alcohol dehydrogenase (ADH) and aldehyde dehydrogenase (ALDH) activity were measured in serum. Serum ethanol (EtOH) concentration was decreased at CM treated groups, and the activities of ADH and ALDH were increased dose-dependently at CM treated groups compare to EtOH model group. In clinical chemistry, the values of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were lower in CM treated groups than those in EtOH model group. Additionally, absolute and relative (to body weight) liver weights were statistically decreased in the CM treated groups compared to the EtOH model group. In conclusion, our study showed that cordycepin-enriched C. militaris extract powder exhibits hepatoprotective effect by upregulating the ADH and ALDH enzyme in an alcoholic liver disease model.

Sjogren-Larsson syndrome (SLS) is a rare autosomal recessive neurocutaneous disorder with worldwide incidence of 0.4 per 100,000 people. It is characterized by the triad of congenital ichthyosis, spastic diplegia or quadriplegia, and mental retardation. Herein we report a 2-year-old male child with SLS, asthma, and recurrent pneumonia. SLS was confirmed by a molecular genetics study that revealed a deletion mutation in the ALDH3A2 gene. An ALDH3A2 gene mutation results in dysfunction of the microsomal enzyme fatty aldehyde dehydrogenase and impaired metabolism and accumulation of leukotriene B4, which is a key molecule and a pro-inflammatory mediator in developing allergic diseases, especially asthma. An increased level of leukotriene B4 has been reported in SLS patients. As far as we are aware, this is the first report of SLS associated with asthma and recurrent pneumonia. In conclusion, pediatricians should be aware of and evaluate patients with SLS for possible associated asthma and allergic disorders.
