  • Background: Chronic heavy alcohol consumption may raise the risk of developing type 2 diabetes mellitus. Saponins inhibit apoptosis of pancreatic islet cells and reduce lipid parameters. The present study was designed to investigate the effect of saponin on chronic ethanol-treated diabetic rats. Methods: Long-Evans Tokushima Fatty (LETO) and Otsuka Long-Evans Tokushima Fatty (OLETF) rats were pair-fed a Lieber-DeCarli diet with and without 5% ethanol for 12 wks. Two weeks after starting the pair-feeding with the Lieber-DeCarli diet, intraperitoneal injection of saponin was performed for 10 wks. To perform the experiments, rats were divided as follows: LETO-Control (LC), LETO-Ethanol (LE), LETO-Ethanol-Saponin (LES), OLETF-Control (OC), OLETF-Ethanol (OE), and OLETF-Ethanol-Saponin (OES). Results: The weights of epididymal and mesenteric fat tissue in LES and OES rats were the lightest from among the LETO and OLETF groups, respectively. The secretion of alanine aminotransferase and cholesterol in OES rats decreased significantly compared to their secretion in OC and OE rats, respectively. The islets of the pancreas in LE and OE rats showed clean, unclear, and smaller morphology compared to those of LC, LES, OC, and OES rats. In addition, the expression of insulin in the islets of the pancreas in LC, LES, OC, and OES rats was higher than in LE and OE rats. Conclusion: Saponin may not only be helpful in alleviating the rapid progress of diabetes due to chronic alcohol consumption in diabetic patients, but may also show potential as an antidiabetic drug candidate for diabetic patients who chronically consume alcohol.

  • Physicochemical properties of Rubus coreanus Miquel were examined. Unripened fruit, ripened fruit and leaf of Rubus coreanus Miquel were used as samples. The contents of water, crude protein, crude fat, crude fiber, dietary fiber, and crude ash were studied. The pH, soluble solid content, acidity and color were also measured. In terms of free sugar composition, concentration of glucose and fructose found in unripened fruit had increased in ripened fruit and sucrose was contained in ripened fruit. The major free sugars of leaf were glucose, fructose and sucrose. Citric acid, succinic acid and fumaric acid were found in all three sample groups, unripened fruit, ripened fruit and leaf. The citric acid showed the highest concentration in the unripened fruit as the concentration of 1.21%. Fifteen types of amino acids were analysed from the unripened and ripened fruit of Rubus coreanus Miquel. The leaf contained methionine in addition to those fifteen type amino acids in fruits. The glutamic acid contents of unripened fruit, ripened fruit and leaf were 411, 246.59 and 898.42 mg%, respectively. Among the minerals studied in this research Rubus coreanus Miquel held high level of potassium. The potassium concentrations of unripened fruit, ripened fruit and leaf were 645.07, 216.53 and 815.78 mg%, respectively.

  • Insect hemocytes during metamorphosis were studies by histchemical and autoradiographic methods is Pieris rapae (Lepidoptera). The hemocytes were classified into six types, prohemocytes, plasmatocytes, podocytes, granular hemocytes, spherule cells and oenocytoids on the basis of the transitions in shapes and inclnsions of cytoplasms. Proteins, nucleic acids, polysaccharides and lipids in the hemocytes were detected histochemically from larval to pupal stages to learn the rise and fall of them during growth and metamorphosis. Most of the granules consisted of glycogen, neutral mucopolysaccharides and mucoprotein in addition to some granules of neutral fats and phospholipids were found in the granular hemocytes and spherule cells. Mitotic figures and DNA synthetic activities were observed in every type of hemocytes from 2nd to 5th instars, suggesting the all types of hemocytes originated from the prohemocytes. The cytoplasmic filaments of plasmatocytes and pdocytes extended very long in prepupa and pupa and the vermiform cells were the transformed plasmatocytes due to their further differentiation.

  • Objectives: Previous studies have obtained conflicting findings regarding possible associations between indices measuring carbohydrate intake and dyslipidemia, which is an established risk factor of coronary heart disease. In the present study, we examined crosssectional associations between carbohydrate indices, including the dietary glycemic index (GI), glycemic load (GL), total amount of carbohydrates, and the percentage of energy from carbohydrates, and a range of blood lipid parameters. Methods: This study included 1530 participants (554 men and 976 women) from 246 families within the Healthy Twin Study. We analyzed the associations using a generalized linear mixed model to control for familial relationships. Results: Levels of the Apo B were inversely associated with dietary GI, GL, and the amount of carbohydrate intake for men, but these relationships were not significant when fat-adjusted values of the carbohydrate indices were used. Triglyceride levels were positively associated with dietary GI and GL in women, and this pattern was more notable in overweight participants (body mass index [BMI] ${\geq}25kg/m^2$). However, total, low-density lipoprotein and high-density lipoprotein cholesterol levels were not significantly related with carbohydrate intake overall. Conclusions: Of the blood lipid parameters we investigated, only triglyceride levels were positively related with dietary carbohydrate indices among women participants in the Healthy Twin Study, with an interactive role observed for BMI. However, these associations were not observed in men, suggesting that the association between blood lipid levels and carbohydrate intake depends on the type of lipid, specific carbohydrate indices, gender, and BMI.

  • Objectives: The associations between the eating behavior and energy and macronutrient intake from meals and snacks consumed during different times of the day across the menstrual cycle were investigated in 74 healthy female college students. Methods: A 9-day food record was collected during the last 3 days before menstrual onset (phase 1) and the first 3 days after menstrual onset (phase 2) and from the 4th to the 6th day after menstrual onset (phase 3), respectively. Anthropometry was assessed and eating behaviors were measured using the Dutch Eating Behavior Questionnaire (DEBQ). Results: External eating was the most prevalent type of eating behavior, followed by restrained eating and emotional eating. Restrained eating was positively associated with energy, carbohydrate and lipid intake at the breakfast and midmorning snack during phase 3. However, emotional eating was also positively related to energy and macronutrient intake at the dinner and after-dinner snack during phase 1 and phase 3, with higher level detected in the phase 1. The association of emotional eating with the snack consumption was highest in phase 1. External eating was positively associated with energy and macronutrient intakes at the dinner and after-dinner snack across the three phases, the highest level being phase 1. In addition, restrained eating was positively associated with the weight, body mass index(BMI), fat mass, waist and hip girth of the subjects. Conclusions: Eating behaviors varied with regard to meals and snacks consumed during different times of the day across the three menstrual phases. Dinner and afterdinner snack consumption in premenstrual phase could be considered as a time when women are more prone to overconsumption and uncontrolled eating.

  • The inhibitory effects of naringenin, kaempherol, and apigenin on the production of cholesterol in HepG2 KCLB 88065 and MCF-7 KCLB 30022 cells were evaluated. In this study, quercetin was used as a reference reagent. After incubation for 3 days, fat-soluble contents of both cell types were extracted by using the Folch method and the cholesterol contents in both cultured cells were determined by high performance liquid chromatography. The concentration of cholesterol in untreated each tissue cells was $12.2{\pm}0.11$ and $8.83{\pm}0.12\;mg/g$ of lipid, respectively. The total concentration of each flavonoid was adjusted to 0, 35, or $350{\mu}M$ in the culture broth. As the results, the addition of 2% methanol and dimethyl sulfoxide (DMSO) to the media (control for flavonoid solvents) did not significantly affect cell growth; however, DMSO caused an increase in the production of cholesterol. Each flavonoid inhibited the production of cholesterol in both HepG2 and MCF-7 cells at the concentration of $35{\mu}M$ above. In addition, the inhibitory effect of kaempherol on the production of cholesterol in these cells was greater than the other flavonoids tested and HepG2 cells are more sensitive to flavonoids than MCF-7. From the results, the inhibitory effects of flavonoids on cholesterol production are different depending on the cell type.
