  • The effectiveness of the extracts of Alnus japonica and Portulaca oleracea, which are effective in improving alcohol-induced liver damage, was confirmed using acute and chronic alcoholic liver injury animal models. In the acute alcoholic liver injury model, dieting Alnus japonica and Portulaca oleracea complex (ALPOC) at a dose of 50 mg/kg showed no significant change in liver or body weight, while measured plasma ALT activity to be deficient (28.12 U/ml) compared to the alcohol intake group (42.5 U/ml), and confirmed that restored it to an average level. It showed an improvement of 34.9% compared to the alcohol intake group. AST activity confirmed that it showed a very effective liver protection activity by showing a gain of 12.6%. The chronic alcoholic liver damage animal model demonstrated that ALT showed an improvement effect of 25%, and AST showed an effect similar to that of the positive control group, Hovenia extract. In addition, through H&E staining analysis, observed that the ALPOC improved the necrosis and bleeding of the liver. And the ALPOC group showed intense antioxidant activity of 127% or more compared to the alcohol intake group, and this was confirmed to have a very high activity, which is more than 20% higher than that of the hovenia fruit extract.

  • Alcoholic extract of Terminalia arjuna [TA] was evaluated far its hepatoprotective activity against carbon tetrachloride (CCl$_4$)-induced hepatic damage in rats. The hepatoprotective activity of TA was evaluated by measuring levels of serum marker enzymes like serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT), serum alkaline phosphatase (SALP). The serum levels of total proteins(TP), total albumins (TAL) and bilirubin (BILN) were also estimated. The histological studies were also carried out to support the above parameters. Silymarin (SM) was used as standard drug. Administration of TA (250 and 500 mg/kg/po) markedly prevented CCl$_4$-induced elevation of levels of SGOT, SGPT, SALP, TP, TAL and BILN. These biochemical observations were supplemented by histopathological examination of liver sections. Alcoholic extract of TA also shown significant in-vitro free radical scavenging activity against 1, 1-diphenyl-2-picryl hydrazyl (DPPH) and nitric oxide (NO) radicals. Thus, the present study provides a scientific rationale for the traditional use of this plant in the management of liver diseases.

  • Alcoholic extract of seeds of Sesamum indicum (SI, 1-30mg/kg) caused hypotensive action in anesthetized rats. Heart rate was also decreased at slightly higher doses (10-30 mg/kg). Pretreatment with atropine (2 mg/kg) abolished these cardiovascular responses. In isolated spontaneously beating atria from guinea-pigs. SI caused decrease in force and rate of atrial contractions. In isolated guinea-pig ileum and rat uterus, SI (100-1000 ug/ml) produced contractile responses. All these actions of SI were abolished in the presence of atropine ($1\mu$M). These results indicate that alcoholic extract of seeds of Seamum indicum contains acetylcholine-like constituent(s) which explains some of the folkloric uses of plant.

  • Four anthocyanins were isolated from the acidic alcoholic extract of Syzygium cumini fruits growing in Egypt: Pelargonidin-3-O-glucoside, pelargonidin-3,5-O-diglucoside, cyanidin-3-O-malonyl glucoside, and delphenidin-3-O-glucoside. They were identified by the chromatographic, TLC and PC, and spectral analyses, UV, $^1$H-NMR and FAB/MS. The fruits were found to contain 0.03 gm % anthocyanins calculated on fresh weight basis calculated by spectrophotometric assay. Cytotoxic activity of total alcoholic extract of the fruits was performed against several types of tumor cell lines using the SRB assay. The tested extract exhibited significant cytotoxic activity for MCF7 (breast carcinoma cell line) (IC$_{50}$= 5.9 ${\mu}$g/mL), while the IC$_{50}$ was > 10 ${\mu}$g/mL for both Hela (Cervix carcinoma cell line), HEPG2 (liver carcinoma cell line), H460 (Lung carcinoma cell line) and U251 (Brain carcinoma cell line).

  • Onions are considered to be a promising source of the alcoholic drink because they are rich in sugar, amino acids and various nutrients. To isolate strains of Saccharomyces cerevisiae producing ethanol of higher concentration, 19 strains were subjected to screening. Among them, the strain producing the highest concentration of ethanol was OJ-8 strain. Onion's oder was effectively removed by treatment for 30 min with 10% (w/v) charcoal against medium and then heat treatment of onion extract for 40 min at $100^{\circ}C$. The optimum conditions for alcoholic fermentation was investigated in medium containing the onion extract. The optimal conditions for ethanol production was obtained by standing culture for 5 days at $25^{\circ}C$ with 5% inoculum volume.

  • Background: Alcoholic steatosis is the earliest and most common liver disease, and may precede the onset of more severe forms of liver injury. Methods: The effect of Korean Red Ginseng extract (RGE) was tested in two murine models of ethanol (EtOH)-feeding and EtOH-treated hepatocytes. Results: Blood biochemistry analysis demonstrated that RGE treatment improved liver function. Histopathology and measurement of hepatic triglyceride content verified the ability of RGE to inhibit fat accumulation. Consistent with this, RGE administration downregulated hepatic lipogenic gene induction and restored hepatic lipolytic gene repression by EtOH. The role of oxidative stress in the pathogenesis of alcoholic liver diseases is well established. Treatment with RGE attenuated EtOH-induced cytochrome P450 2E1, 4-hydroxynonenal, and nitrotyrosine levels. Alcohol consumption also decreased phosphorylation of adenosine monophosphate-activated protein kinase, which was restored by RGE. Moreover, RGE markedly inhibited fat accumulation in EtOH-treated hepatocytes, which correlated with a decrease in sterol regulatory element-binding protein-1 and a commensurate increase in sirtuin 1 and peroxisome proliferator-activated receptor-a expression. Interestingly, the ginsenosides Rb2 and Rd, but not Rb1, significantly inhibited fat accumulation in hepatocytes. Conclusion: These results demonstrate that RGE and its ginsenoside components inhibit alcoholic steatosis and liver injury by adenosine monophosphate-activated protein kinase/sirtuin 1 activation both in vivo and in vitro, suggesting that RGE may have a potential to treat alcoholic liver disease.

  • Non-alcoholic fatty liver disease (NAFLD) is common in obesity. However, weight reduction alone does not prevent the progression of NAFLD to end-stage disease associated with the development of cirrhosis and liver disease. In a previous experiment, 50% ethanol extract of Acanthopanax senticosus stem bark (ASSB) was found to reduce body weight and insulin resistance in high fat diet-induced hyperglycemic and hyperlipidemic ICR mice. To evaluate the anti-steatosis action of ASSB, insulin-resistant ob/ob mice with fatty livers were treated with ASSB ethanol extract for an 8 week-period. ASSB ethanol extract reversed the hepatomegaly, as evident in reduction of % liver weight/body weight ratio. ASSB ethanol extract also specifically lowered circulating glucose and lipids, and enhanced insulin action in the liver. These changes culminated in inhibition of triglyceride synthesis in non-adipose tissues including liver and skeletal muscle. Gene expression studies confirmed reductions in glucose 6-phosphatase and lipogenic enzymes in the liver. These results demonstrate that ASSB ethanol extract is an effective treatment for insulin resistance and hepatic steatosis in ob/ob mice by decreasing hepatic lipid synthesis.

  • The adrenergic blocking activity and refractory period of cardiac muscle on isolated rabbit atria were measured after administration of Scutellaria. In rabbits and cats the antiarrhythmic action of Scutellaria on atrial and ventricular arrhythmias produced by epinephrine or ouabain was examined and also compared with that of propranolol and quinidine. The alcoholic extract of Scutellaria produced a marked decrease in heart rate and contractile amplitude of the isolated rabbit atria. Pretreatment with Scutellaria rendered the atria to fail to respond to epinephrine, indicating that this crude drug possesses an adrenergic blocking activity. The extract produced a marked prolongation of the refractory period of atrial muscle. The extract effectively abolished the spontaneous arrhythmia occurring in the isolated rabbit atria. As propranolol and quinidine it also suppressed the atrial arrhythmia induced by ouabain. The extract prevented, as propranolol and quinidine, the induction of ventricular arrhythmia arising from excessive dose of epinephrine in anesthetized rabbits and cats. With regard to the ventricular arrhythmia induced by a continuous infusion of ouabain, the alcoholic extract of Scutellaria exerted some suppressive effect in anesthetized rabbits but no effect on cats. From the above results, it may be concluded that Scutellaria is effective against atrial and ventricular arrhythmias. The antiarrhythmic effects of this drug may be the result of adrenergic beta receptor blocking and cardiac depressive activities including prolongation of the refractory period of cardiac muscle.

  • Fermentation characteristics of kwahaju (a typical Korean traditional alcoholic beverage) base were investigated during fermentation with different contents of nuruk (Korean-style bran koji) extract. The nuruk extract which was prepared by incubating the mixture of nuruk powder and water at $25^{\circ}C$ overnight and by filtering it was used to be 0.6%, 2.7%, 5% and 10% (v/v). Total and reducing sugar contents as well as acidity of the kwahaju base with 0.6% nuruk extract were higher than those with 2.7%, 5% and 10% at the fermentation end. Final pH values of all the base samples were ranged from 3.3 to 4.1. Alcohol concentrations of the base samples with 2.7%, 5% and 10% nuruk extract were higher than those with 0.6%. Microbial growth rate was great and inner temperature was high in the sample with high content of nuruk extract, but fermentation period was short. Total sugar consumption and alcohol production increased as the content of nuruk extract increased, but total acid production decreased. The base sample with 10% nuruk extract showed the most excellent fermentation efficiency. Fusel oil content of the base sample with 2.7% nuruk extract was the highest (457.3 ppm), and those wity 5% and 10% nuruk extract were 438.9 ppm and 442.6 ppm, respectively. The sample with 0.6% nuruk extract had the lowest content (409.5 ppm). Sensory evaluation of both the kwahaju base and kwahaju mix with 25% and 40% alcohol by adding soju (Korean distilled liquor) showed that the base with 2.7% nuruk extract had the highest score, and that the kwahaju mix with 25% alcohol had higher score than that with 40%. The sensory results on overall desirability were consistent to those on color and alcohol concentration, and it turned out that the two factors were important to make kwahaju.
