  • This study examined the protective effects of an ethanol extract of Youngia denticulata leaf (YDL) and Youngia denticulata root (YDR), and Youngia sonchifolia leaf (YSL) and Youngia sonchifolia root (YSR) on acute ethanol-intoxicated rat. The rats were pretreated with an ethanol extract of YDL, YDR, YSL and YSR for 4 weeks before being exposed to ethanol (5 g ethanol, po/kg BW). The biochemical indices (hepatic alcohol metabolic enzymes and serum ALT activities, and hepatic and serum lipid profiles) were examined to evaluate the protective effects. The hepatic ADH activities in all experimental groups were not changed significantly by acute ethanol after a pretreatment with the YS and YD ethanol extracts. In contrast, the ALDH activity in EC (ethanol control) was higher than that of NC (normal control); these activities in the YDL and YSL groups were significantly higher than that of the EC group. On the other hand, acute ethanol exposure resulted in a significant increase in the serum TG, total cholesterol, LDL-cholesterol, hepatic TG, total lipid and cholesterol levels, and serum ALT activity, and a decrease in the serum HDL-cholesterol. A pretreatment with the YS and YD ethanol extracts dramatically attenuated these adverse effects. In particular, the YDL pretreatment markedly suppressed the ethanol-induced increase in the serum and hepatic TG and total cholesterol levels. Furthermore, serum ethanol was decreased by a pretreatment with YSL, YSR, YDL, or YDR. Overall, YD and YS ethanol extracts attenuate acute ethanol-induced hyperlipidemia and fatty liver significantly. Nevertheless, further study will be needed.

  • Purpose: Obesity has recently emerged as a significant health problem in the pediatric population, and the prevalence of non-alcoholic fatty liver disease is increasing in tandem with a significant rise in childhood obesity. Therefore, this study was conducted to clarify the risk factors of non-alcoholic steatohepatitis in obese children. Methods: We enrolled 84 obese children who visited the pediatric obesity clinic at Yeung-Nam university hospital. The patients were divided into two groups based on their alanine aminotransferase (ALT) level (separated at 40 IU/L), and the mean of ages, total cholesterol levels, HDL-cholesterol levels, LDL-cholesterol levels, triglyceride (TG) levels, as well as the mean obesity index, and body fat percentage of the two groups were then compared. Results: When the mean of ages ($10.5{\pm}1.6$ vs. $10.7{\pm}2.0$ years), total cholesterol levels ($183.0{\pm}29.1$ vs. $183.7{\pm}31.3$ mg/dL), HDL-cholesterol levels ($53.0{\pm}10.2$ vs. $55.7{\pm}13.0$ mg/dL), LDL-cholesterol levels ($113.4{\pm}30.2$ vs. $113.0{\pm}30.0$ mg/dL), triglyceride levels ($99.4{\pm}62.9$ vs. $114.2{\pm}47.3$ mg/dL), obesity indexes ($44.7{\pm}12.2$ vs. $47.9{\pm}15.1%$), and body fat percentages ($32.7{\pm}5.0$ vs. $34.0{\pm}4.8%$) of group 1 (ALT${\leq}$40 IU/L) were compared with those of group 2 (ALT${\geq}$41 IU/L), no significant differences were observed (p>0.05). However, hypertriglyceridemia (TG${\geq}$110 mg/dL) was more frequent in group 2 than in group 1 (p=0.023). Conclusion: TG may be an important risk factor in non-alcoholic steatohepatitis and further study regarding the risk factors in non-alcoholic steatohepatitis is required.

  • It was reported that the novel compounds (LP9M80-H) of $Liriope$ $platyphylla$ regulate glucose transporter (Glut) biosynthesis by activating the insulin-signaling pathway in the liver and brain of ICR mice. To investigate the therapeutic effects of LP9M80-H on the pathology of diabetes and obesity, alterations of key factors related to symptoms were analyzed in the Otsuka Long Evans Tokushima Fatty (OLETF) rats treated with LP9M80-H for 2 weeks. The abdominal fat masses in the LP9M80-H-treated group were lower than the vehicle-treated group, although there was no difference in body weight between the two groups. Additionally, when compared to the vehicle-treated group, LP9M80-H treatment induced a significant decrease in glucose levels and an increase in the insulin concentration in the blood of OLETF rats. A high level of insulin protein was also detected in pancreatic ${\beta}$ cells of LP9M80-H-treated OLETF rats. A significant reduction in the concentration of lipids and adiponectin was detected only in LP9M80-H-treated OLETF rats. Furthermore, the expression of insulin receptor ${\beta}$ and the insulin receptor substrate (IRS) was dramatically decreased in LP9M80-H-treated OLETF rats compared to the vehicle-treated group. Of the glucose transporters located downstream of the insulin-signaling pathway, glucose transporters (Glut) -2 and -3 were significantly decreased in LP9M80-H-treated OLETF rats, while the level of Glut-4 was maintained under all conditions. Therefore, these results suggest that LP9M80-H may contribute to relieving symptoms of diabetes and obesity through glucose homeostasis and regulation of lipid concentration.

  • In order to determine nutrition education needs and related problems, a study was conducted of children's dietary habits, focusing on parental influence and degree of agreement between parent and child on foods liked, accepted, or disliked, in addition to a general survey of food atiitudes. This study was conducted throughout a two-month period, June to July of 1974. One thousand children of both sexes, from the fifth grade, junior and senior high schools of Seoul city, and their 2,000 matched parents, were surveyed, Teachers distributed questionnaires in the classroom and assisted the children in answering. Questionnaires also were distributed to the parents through their children, after the teachers explained the procedure of study. As to the influence of parents' food preferences, the following conclusiolns can be reached, in light of the results of chi-square tests conducted: 1. Agreement between mother and child on food preference was much higher than that between father and child, regardless of sex or birth order of the child. This observed difference in degree of agreement was greatest for children in the middle birth order, and greater for girls than for boys. 2. Various food attitudes: a. Food preferences: Beef, milk, and mandoo (boiled or steamed, filled dumplings) were extremely well liked by all subjects, regardless of age or sex. Cucumber, lettuce, and spinach also were lied. Most disliked foods were fatty layers of pork and liver. Cooked rice in the too wet or too dry state and pork were low preference items. b. Socioeconomic background and dietary practice: Higher educational background of the wife and higher income level of the family were associated with greater knowledge of nutrition, and interest in family nutrition and in introducing new foods to the family. But use of food as prize or punishment was found, regardless of the mother's educational and economic status. c. Change of food habit: Over 70 percent of subject had changed ad improved their dietary habits, mostly by reason of husbands' and wives' mutual influence after marriage. This study emphasized the great importance of nutrition eudation for mothers, and their prominent role and responsility in guiding the family to better nutrition, whatever the mother's educational background.

  • This study was conducted to know the differences in pathology between artificially induced hemorrhagic anemia (EHA) and hemolytic anemia (ELA) during the anemic and recovery course, using Nile tilapia (Oreochromis niloticus). EHA were induced by repeated bleedings with a volume of about 1% of body weight through caudal vein. ELA were induced by intraperitoneal injections of 1% phenylhydrazine for 2 times. A period of 16 to 49th day was arbitrarily taken as a recovery phase. There were no prominent clinical signs and gross findings except for pale gills during the anemic state of both. Characteristic erythrocytes with a weekly stained cytoplasm started appearing on the 12th day in both and were still noted on the 49 and 20th day respectively in EHA and ELA. EHA and ELA were normocytic hypochromic and macrocytic normochromic in type respectively, although both were normocytic hypochromic during the recovery phase. In liver, fatty degeneration around central vein on the 12-38th day in EHA and hyaline degeneration around central vein on the 12-26th day in ELA were found. In head kidney, increased hemopoiesis was observed on the 12-26th day in EHA and on the 2-12th day in ELA, and macrophages engulfing erythrocytes were observed on the 16-38th day in EHA and on the 2-12th days in ELA. In spleen, activated ellipsoids on the 12-26th day in EHA. and on the 2-20th day in ELA. In ELA, severe accumulation of hemosiderin in both spleen and head kidney were constantly noted from the 2-49th day. On the 49th, Ht was recovered but Hb was still lower than that of control in both anemia.

  • Ixeris dentata var. albiflora Nakai, a herbal plant, is often used to make a strong stomach as an antiphlogistic used when dyspepsia and to improve appetite in Korea and China. And also it is used for adult diseases such as diabetes and liver diseases as Korean traditional medicine. In this study, the composition and DPPH radical scavenging activities of the root of Ixeris dentata var. albiflora Nakai and its effects on cell viability on vero and chang cells were investigated. Moisture, crude ash, crude protein and crude lipid were 79.14, 2.49, 8.28 and 2.56 g/100 g respectively. The highest mineral content was K. The major free sugars were glucose, fructose and sucrose. Major fatty acid are linoleic acid, palmic acid and linolenic acid. Major amino acids were glutamic acid, arginine and aspartic acid and the total contents of amino acids were 28.12 mg/g. The methanol extracts were further fractionated with n-hexane, chloroform, ethylacetate, butanol and water to get an active fraction. In addition, cell viabilities in each fraction were determined. Methanol extract, butanol, and aqueous fraction showed strong survival rates in vero cell and chang cell viability test, and hexane, chloroform, and ethylacetate fraction were examined for toxin in a cell. The root of Ixeris dentata var. albiflora Nakai had scavenging activities against DPPH radicals in a dose-dependent assay. Ethylacetate fraction's SC50 was $6.8\{\mu}g/mL$, very strong DPPH radical scavenging activities, but water fraction did not show any activity.

  • In the previous symposium, authors reported about anti-atherogenic action of Panax ginseng, saying that red-ginseng powder increased serum HDL-cholesterol, decreased total cholesterol, TG, NEFA, in addition, decreased platelet adhesiveness. Later, Toyama group including me. reported that ginsenosides esp. $Rb_2$ enhanced HDL and decreased LDL. Also Matsuyama group and Kinki Univ. group reported that ginsenosides $Rg_1,\;Rb_2,$ etc. inhibited platelet aggregation. This paper will be divided into two parts: Experimental and clinical Experimental study; Using a highcholesterol-cholic acid-fed rats, effects of red ginseng extract and several ginsenosides on serum apoprotein-lipoproteins in relation to prostaglandins. Rats received $2\%$ cholesterol 1-1$\%$ cholic acid diet, ginseng extract or ginsenosides 2.5mg/100g/day for 9 days. Red ginseng extract, ginsenosides $Rb_2,\;Rc,\;Rb_1,\;and\;Rg_1,\;esp.\;Rb_2,$ increased HDL, apo-AI, Aii and $PGI_2,$ while they decreased LDL, apo-B and $TXA_2$. Clinical study: Effect of red ginseng powder on hyperlipidemia was observed. Long term administration of red ginseng powder manufactured by Office of Monopoly, Republic of Korea and offered by Japan-Korea Korean Ginseng Co., Kobe, at the dose of 2.7 g/day, was performed in patients with hyperlipidemia up to 4 years. The significant increase in serum HDL-cholesterol and also the significant decrease in total cholesterol, atherogenic index, TG, NEFA and lipoperoxide was observed with 3-48 month administration of red ginseng. Conclusions: Red ginseng and ginsenosides improved hyperlipidemia in rats and in man, with the improvement of blood apoproteins, lipoproteins and prostaglandins in experimental hyperlipidemic animals.

  • Obesity is a pro-inflammatory state that contributes to the development of metabolic disorders such as hyperlipidemia, insulin resistance, type 2 diabetes, non-alcoholic fatty liver, and cardiovascular disease. In this study, we evaluated the inhibition of adipogenesis in 3T3-L1 cells and in high-fat diet (HFD)-induced obese mice by Peucedanum japonicum Thunberg L. water extract (PJT). Lipid accumulation measurement indicates that PJT markedly inhibited adipogenesis in a dose-dependent manner. RT-PCR results demonstrated that the mRNA expression of adipogenic transcription factors such as peroxisome proliferator-activated receptor-γ (PPARγ) and CCAAT/enhancer binding protein-α (C/EBPα) in 3T3-L1 cells were significantly down-regulated by PJT treatment. Oral administration of PJT (100, 300, and 500 ㎎/㎏, b.w/daily for 4 weeks) was conducted in high-fat diet induced obese mice and C57BL/6 mice. The PJT-administered group of HFD-induced mice had a lower body weight gain, along with decreased serum levels of glucose, triglycerides, and total cholesterol compared with the control mice, however, the HDL-cholesterol/total cholesterol ratio was increased. Furthermore, the elevated mRNA expression levels of adipogenesis related genes in the white adipose tissue of obese mice were significantly suppressed by PJT. These results indicate that PJT exhibits anti-obesity effects in obese mice by decreasing in serum lipid levels and lipogenesis related gene.

  • Purpose : The incidence of type 2 diabetes mellitus in children has been increasing worldwide recently, which is thought to be related to the increasing prevalence of obesity. We investigated to evaluate the incidence and the characteristics of type 2 diabetes mellitus in children and also analysed the relationship between intrauterine growth retardation and type 2 diabetes mellitus. Methods : We investigated 25 children diagnosed as type 2 diabetes mellitus between March 1990 and December 2000. The analysis was performed retrospectively with medical records based on the clinical characteristics and laborotory findings. Results : Incidence of type 1 and type 2 diabetes mellitus in children has been increasing since 1990. We demonstrated an increase in the percentage of type 2 diabetes mellitus children from 5.3% in 1990 to 21.0% in 2000. Sixty eight percent of patients(17/25) were classified as obese group. Initial symptoms at first visit were polyuria, polydipsia and polyphagia 48%(12/25), asymptomatic glycosuria 40% (10/25), weight loss 8%(2/25) and obesity 4%(1/25). The mean age at diagnosis was $12.9{\pm}1.8$ years. 64%(16/25) of patients had positive family history of type 2 diabetes mellitus. Autoanti-bodies were positive in 18.1%(4/22) of patients. Twenty eight percent (7/25) of patients had an associated disease and two patients had fatty liver in association with obesity. Treatment consisted of diet, exercise, education and oral hypoglycemic agents. Three patients were treated with insulin as well as oral hypoglycemic agents because of poor blood glucose control. Long-term diabetic complications occurred in 4 patients. Intrauterine growth retardtion was found in 34.6%(9/25); 88.9% (8/9) of these patients were non-obese group. Conclusion : The increase in the incidence of type 2 diabetes mellitus in children is thought to be related to the increasing prevalence of obesity. The non-obese group of patients might be associated with intrauterine growth retardation.
