  • There is a marked increase in geriatric disease, especially liver disease, due to the continuous increase in alcohol and fat consumption. Since the fatty liver, induced by alcohol or fat, is basically from abnormalities in the lipid metabolism, it is possible that fatty acid binding protein(FABP) which is related to the fatty acid metabolism may also be abnormal in these livers. FABP is a small molecular weight protein family present in cytosol in high concentration. It has been proposed as a fatty acid transfer protein and as a binding protein responsible for controlling intracellular free fatty acid concentration. In this research, we have examined the relationship between liver FABP and fatty liver induced by alcohol or high cholesterol diet. Rats were fed one of either semipurified liquid diets; control diet containing 65% carbohydrate, 20% protein, and 15% fat or high cholesterol diet containing 1%(w/w) cholesterol or alcohol diet containing 37% of alcohol instead of carbohydrate. After 5 weeks of feeding period, all rats received commercial chow diet for 5 weeks to examine recovery effect. Liver and blood samples were collected at 0, 1, 3, 5 and 10 weeks to analyze lipid compositions. FABP was purified from liver cytosol and injected to rabbit to obtain antiserum. Liver FABP amount was determined by SDS-PAGE and western blotting methods. Fatty acid binding capacity was determined by binding of 14Cpalmitate with the delipidated liver cytosol. Consumption of alcohol increased serum cholesterol, triglyceride concentration and decreased HDL-cholesterol concentration after 5 weeks. Serum apolipoprotein B concentration increased after 3 weeks and LDL-cholesterol and apolipoprotein A concentration changed after 1 week. Liver cholesterol and triglyceride concentration increased after 3 weeks. Consumption of high cholesterol diet changed liver and serum lipid composition after 3 weeks. Swiching to normal diet for 5 weeks did not normalize most of lipid composition in serum and liver except serum and liver except serum cholesterol, triglyceride and liver cholesterol. Liver cytosol FABP content and the fatty acid binding capacity decreased dramatically after 1 week with alcohol consumption. This results indicate that FABP content changes before the changes before the changes of blood or liver lipid composition, suggesting changes of FABP may cause development of the fatty liver induced by alcohol and can be used as an index of detecting a early development of fatty liver.

  • In this study, low viscous O/W (oil-in-water) nano-emulsion with fatty acid and fatty alcohol was prepared by phase inversion emulsification method using Tween 80 and Span 80 widely used in cosmetic products. The particle size of the nano-emulsion was increased as increasing the concentration of fatty alcohol in oil phase. Adjusting the HLB of mixed surfactants, a stable nano-emulsion with a narrow size distribution was produced. Similar change in viscosity and electrical conductivity in both systems containing fatty acid and fatty alcohol was shown in the vicinity of the phase inversion point. However, high viscosity was shown in a wide range of different aqueous fraction unlike the system consisting only oils and surfactants. The low viscous nano-emulsion with less than 100 nm droplet size was stable for one month or more at room temperature. O/W nano-emulsions with low viscosity containing fatty acid or fatty alcohol produced by low-energy emulsification method can be widely used as formulations of cosmetics.

  • Toner particles used in laser and xerographic printing process is fused on paper surface so strongly that they tend not to detach easily from the recylced paper surface during pulping. Furthermore, the removal efficiency of detached toner particles by conventional screening and flotation process has limitation due to the platy shape and large size of detached toner particles. It has been shown that the removal efficiency of toners in the screening process can be increased by agglomerating the toner particles with fatty alcohol. It is not possible, however, to remove small and platy toner particles by screening process. These small and platy toner particles should be removed by flotation process. In this study the effect of fatty alcohol that used for toner agglomeration on flotation efficiency has been examined. It was shown that flotation efficiency decreased when fatty alcohol was used most probably due to its effect of reducing hydrophobicity of toner particles.

  • The objective of this study is to analyze the influences of fatty alcohols and fatty acids on rheological properties of oil in water (O/W) emulsions using viscosity and rheograms. As the chain length of fatty alcohols and fatty acids lengthened, the viscosity of emulsions was increased. The influence of fatty alcohols on viscosity enhancement was stronger than that of fatty acids. Both stearyl alcohol and cetearyl alcohol, which have carbon chain length similar to lipophilic portion of surfactant used in emulsion preparation, had showed the best increase in viscosity of O/W emulsions. O/W emulsions prepared with fatty alcohols and fatty acids were pseudo-plastic fluid and they showed shear thinning behaviour like as the common cosmetic emulsions. O/W emulsions prepared with cetyl alcohol, cetearyl alcohol and stearyl alcohol were thixotropic fluids and thixotropy increased with an increase in the concentration of fatty alcohols and fatty acids. Also O/W emulsions prepared with fatty alcohols were more thixotropic than those prepared with fatty acids. For the sake of viscosity increase related to O/W emulsions stability and spreadability enhancement related to payoff, it is thought that fatty alcohols are more useful than fatty acids in the O/W emulsions as the emulsion stabilizer.

  • Although alcohol drinking may cause fatty liver to induce hepatocytic injury, other factors lead to it. We designed this study to investigate the differences in serum iron, cardiac, and biochemical indices in men with fatty liver and the difference between alcohol drinkers (Alcohol group) and non-drinkers (Non-alcohol group). The alcohol group had higher body indices than the non-alcohol group. Systolic and diastolic blood pressure (SBP and DBP), and right and left intraocular pressure in the alcohol group were higher than those in the non-alcohol group. Hemoglobin, hematocrit, mean corpuscular hemoglobin, mean corpuscular hemoglobin concentration, and monocyte counts were higher in the alcohol group than in the non-alcohol group. Alanine aminotransferase, ${\gamma}$-glutamyltranspeptidase, total cholesterol, triglyceride, low-density lipoprotein cholesterol, glucose, creatinine, uric acid, iron, total iron binding capacity, and ferritin levels in the alcohol group were greater than those in the non-alcohol group. The present data reveals that alcohol-induced fatty liver has more elevated level of iron indices than in non-alcohol fatty liver as well as biochemical and cardiac indices, indicating that alcohol- induced fatty liver may cause possibility of adult diseases including cardiovascular disease and metabolic syndrome.

  • This study was performed to investigate the effect of dietary intakes and nutritional status for fatty liver male patients with fatty livers. General characteristics, nutritional knowledge, and dietary intakes were obtained from fatty liver male patients aged 20-60yr living in Seoul and Kyunggi province by individual interview and blood samples. The Results were as follows : the mean age of the subjects was 39yrs. Old and over half the subjects were overweight. Although nutritional knowledge, recognition, and accuracy scores were good, these did not affect the subject's health. The average alcohol intake of subjects was 79.8g/day and the drinking duration was 5-40yrs(average : 17yrs). The subjects drank alcohol over 4tiles/week and preferred Soju. Most side dishes taken with alcohol drinking by the subjects were foods from animal sources. Half of the subjects also drank alcohol the next day for breakfast as a hangover-chaser. The reasons for drinking were due to social relationships and by habit. Vitamin D and folate were lower than the RDA for Koreans, and other nutrient amounts were higher than the RDA. The amounts of aspartate amino-transferase(AST), Alanine amino-transferase(ALT), ${\gamma}$-glutamyl transpeptidase(${\gamma}$-GTP), Triglyceride(TG) for the subjects were higher. In conclusion, fatty liver patients drank excessively and frequently. It seems that heavy alcohol drinking is more prone to overweight or obese people and contributes to fatty livers. Therefore, the subjects need to be taken effectively educated about alcohol-induced liver damage and the importance of a balanced diet for on healthy liver.

  • Alkyl polyglucosides were synthesized by solvent-free glycosidation using ultrasonic emulsification. We examined glycosidation conditions of fatty alcohol with glucose hydrate and anhydrous glucose in the presence of p-toluenesulfonic acid. Glucose was emulsified in a molar excess of fatty alcohol for 20 minutes with a ultra-sonicator at room temperature and converted in a stirred reactor to more than 95% polyglucoside within $2.5{\sim}3.5$ hr under $20{\sim}30$ mmHg at $110^{\circ}C$ with a three-fold molar ratio of fatty alcohol to glucose in the presence of 1mol% p-toluenesulfonic acid. It was possible to obtain a polyglucoside mixture of HLB 13 consisting of 65% monoglucoside and 35% oligoglucoside with less than 1% of fatty alcohol.

  • The purpose of this study is to investigate dietary factors which influence the conditions of Korean fatty liver patients. The subjects were 83 fatty liver patients living in city, ages of 10 to 60 yrs old, and they were the same patients studied 9 months ago in previous study. The patients were groupsed into 3 groups(improved, similar, worsened groups) according to the changes in disease condition. Nutrient and alcohol intakes and health status were investigated. In improved group, the patients tended to lose weight, the number of exercising patients was increased, the consumptions of calorie, carbohydrate, calcium, phosphorus were decreased. And alcohol intake was decreased markedly and serum total amino acids(AA), EAA, NEAA, BCAA and AMAA contents, EAA/NEAA and BCAA/AMAA ratios were increased. In worsened group, patients tended to gain weight, the number of exercising patients decreased, the consumptions of calorie, protein, carbohydrate, calcium, phosphorus and niacin decreased but vitamin. A intake increased. And also, in this group, alcohol intake of male patients decreased and that of female slightly increased, and serum EAA, BCAA and AMAA contents, EAA/NEAA and BCAA/AMAA ratios, and total fatty acid contents increased and total AA and NEAA contents decreased. In conclusion, it is desirable to reduced weight, stress, alcohol, salt and animal fat consumptions, and to exercise, and to take adequate amount and quality of protein to improve conditions of fatty liver patients.

  • The hepatoprotective effect of liposoluble portion of Pyropia yezoensis (PYLP) was investigated against alcohol-induced liver injury in mice. Fatty acids were predominant in PYLP obtained from hexane fraction of 70% EtOH extract after ultrasonication. In particular, polyunsaturated fatty acids such as eicosapentaenoic acid and linoleic acid accounted for 56.91% of the total lipids. PYLP significantly reduced liver damage induced by the alcohol treatment in mice. PYLP treatment increased the activity of antioxidant enzymes including superoxide dismutase, catalase, and glutathion peroxidase by reducing thiobarbituric acid reactive substances. Histological observations showed that PYLP minimizes damage to living tissue induced by alcohol treatment by modulating the expression level of proteins involved in the anti-apoptotic signaling pathway. Our results suggest that PYLP, rich in polyunsaturated fatty acids extracted from the red alga P. yezoensis, will be useful as a potential liver protectant in the hangover industry.
