  • Non-alcoholic fatty liver disease (NAFLD) is caused by fat accumulation and is associated with oxidative stress. In this study, we investigated the potential protective effect of pomegranate (Punica granatum L.) peel extract (PPE) against oxidative stress in the liver of rats with NAFLD. Sprague-Dawley rats were fed a high fat diet (HFD), 20% corn oil, or palm oil for 8 weeks in the presence or absence of PPE. The control group was fed a basal diet. The progression of NAFLD was evaluated histologically and by measuring liver enzymes (alanine transaminase and aspartate transaminase), serum lipids (triglycerides and total cholesterol), and oxidative stress markers. The HFD feeding increased the body weight and caused NAFLD, liver steatosis, hyperlipidemia, oxidative stress, and elevated liver enzymes. Administration of PPE ameliorated the hepatic morphology, reduced body weight, improved liver enzymes, and inhibited lipogenesis. Furthermore, PPE enhanced the cellular redox status in the liver tissue of rats with NAFLD. Our findings suggest that PPE could improve HFD-induced NAFLD via abolishment of hepatic oxidative damage and hyperlipidemia. PPE might be considered as a potential lead material in the treatment of NAFLD and obesity through the modulation of lipid metabolism.

  • Korean food habits, dietary behaviors and perception of food were compared according to gender and age. The subjects were composed of 274 males and 315 females. According to age, the age group of 10s was 26.3%, 20s 24.6%, 30s 16.8%, 40s 18.7%, and 50s and over 13.6%, respectively. The majority (65.2%) of all age groups except the 20s took meals 3 times a day and the ratio 20s eating twice a day was higher than other age groups. All age groups took cooked rice(bap) two or three times a day and the 20s group took smaller amount than other age groups did. The younger age groups of 10s and 20s took larger amount of processed food. The older age groups appeared to have higher frequency of eating fish, bean, vegetable, Kimchi, laver.brown seaweed, soybean oil, sesame oil, coffee, tea, and rice cake(ddhuk). The younger groups have the higher frequency of eating ramyeon, corn flake, milk, milk-processed food, butterㆍmargarine, ham.sausage, carbonated drink candyㆍchocolate, hamburger, and pizza. All age groups perceived cooked rice(bap), meat, fish, egg, vegetable, fruit, and Kimchi to be the delicious, excellent and healthy food. According to the above results, age groups of 30s and over had relatively better food habits compared with those of younger groups. On the other hand, the groups of 10s and 20s had meals irregularly, showed a high ratio of skipping meals, and took processed food much. These results raised a concern of their nutritional imbalance in the future. Therefore, the correct nutritional education must be conducted to make these age groups have a healthy food habits.

  • This study was performed to investigate the anti-obesitic effect of mulberry root-bark on male and female Zucker FA/FA or FA/fa rats. Obesity in the rats was induced by feeding high-lipid diet contained 3% corn oil and 1% cholesterol. Experimental groups in male and female rats were assigned to normal diet group (normal control), high-lipid diet group(positive control) and 3% mulberry root-bark powder in high-lipid diet group (MRC). The mulberry treated-group showed decreases of body weight, FER (food efficiency ratio) value and lipid peroxidation in the liver and increase of high density lipoprotein cholesterol (HDL-C) value, compared with positive control groups. Our findings suggest that mulberry root-bark has a potential role in preventing or improving obesity from the following points of view, body weight, serum lipids and antioxidant enzyme activities.

  • The purpose of this study was to determine the effects of 2-AAF injection time on hepatic lipid peroxide metabolism and cytochrome P450 content in Sprague-Dawley rats fed diets containing high amounts of vegetable oils or animal fats(15%, w/w). Fifty mg of 2-AAF/kg of body weight/day was injected in PEG 300 intraperitonially for 3 consecutive days after 4 or 8 weeks to rats fed corn oil(CO) or lard(LA) diet. The contents of lipid peroxide and cytochrome P450, and the activities of superoxide dismutase(SOD), glutathione peroxidase(GSH-peroxidase) and glutathione S-transferase(GSH-S-transferase) were determined in hepatic microsomal or cytosolic fraction. Microsomal thiobarbituric acid reactive substances(TBARS) and cytochrome P450 contents increased in Co group injected 2-AAF after 4weeks. Cytosolic SOD activity increased in CO group injected 2-AAF after 4 weeks and in LA group injected 2-AAF after 4 or 8 weeks. Cytosolic GSH-S-transferase activity increased in LA group compared to CO group without 2-AAF injection. GSH-S-transferase activity increased in CO group injected 2-AAF after 4 or 8 weeks and in LA group injected 2-AAF after 4 weeks. Therefore, it may be suggested that 2-AAF injection increase the contents of lipid peroxide or cytochrome P450, and detoxifying enzyme activities in rats fed CO diet for short period and in rats fed LA diet for longer period.

  • The fructus of Gardenia jasminoides Ellis (GF) has been widely used as a natural colorant in Asian countries, and also as a Chinese traditional medicine for its homeostatic, antiphlogistic, analgesic, and antipyretic effects. In the present study, its main component, crocin, was fermented with lactic acid bacteria (LAB) and their antihyperlipidemic activity was measured. The GF extract, fermented GF (F-GF), crocin, and fermented crocin (F-crocin) significantly inhibited the increase of serum triglyceride (TG) level in corn oil feeding-induced triglyceridemic mice, as well as that of serum TG and total and LDL cholesterol levels in Triton WR-1339-induced hyperlipidemic mice. These agents also showed hypolipidemic activity in hyperlipidemic mice induced by high fat diet for 5 weeks. F-GF and F-crocin exhibited more potent hyperlipidemic effects than GF and crocin. The results suggest that the hypolipidemic effect of GF and crocin can be synergistically activated by LAB, and that F-GF and F-crocin may improve hyperlipidemia in clinic, compared with GF and crocin.

  • Imported and exported agricultural products are facing a very difficult time due to the rising distribution costs spurred by the increasing labor and oil prices. High empty transfer rates, which take place on a return route after the regular transportation of imported and exported agricultural products, are especially a major cause of the rising distribution costs. In an effort to overcome those limitations, this study set out to examine the transportation stages connecting harbor warehouses, processing plants, and central distribution centers on the circulation route of such imported grains as wheat, barley, corn, and soybean and the transportation route from the warehouses devoted to exported agricultural products to harbors for such exported agricultural products as apple, pear, and persimmon in order to develop a model on the creation of a compound logistics complex for processing plants and transshipment of imported and exported agricultural products. The study also promoted the logistic rationalization of imported and exported agricultural products by creating a compound logistics complex that would combine processing plants for imported agricultural products and transshipment functions for exported agricultural products.

  • Pancreatic lipase-inhibitory activity of the rhizome of Rhei Rhizoma and its antihyperlipidemic activity were measured. Rhei Rhizoma inhibited pancreatic lipase with $IC_{50}$ value of 6.5 mg/ml (triolein as a substrate). Rhei Rhizoma significantly inhibited serum TG level in corn oil feeding-induced mice, and serum TG and cholesterol in Triton WR-1339-induced hyperlipidemic mice. However, Rhei Rhizoma did not show the hypolipidemic activity in high cholesterol diet-induced hyperlipidemic mice. When in vitro pancreatic lipase-inhibitory and in vivo antihyperlipidemic activities of Whangryunhaedoktang (WT) and Chunghyuldan (CD), which is consisted of ingredients of WT and Rhei Rhizoma, were measured, CD exhibited more potent inhibitory activities than WT. Therefore these results suggest that antihyperlipidemic activity of Rhei Rhizoma and CD may be more or less originated from the inhibition of pancreatic lipase.

  • To evaluate the anti-hyperlipidemic effect of Brassica rapa L. and its major compound, $\beta$-sitosterol, the present study was undertaken, hypercholesterolemia was induced in rats with poloxamer-407, Triton WR-1339, 30% corn oil high cholesterol diet. The ethanol extract of Brassica rapa L. significantly decreased total cholesterol (TC), phospholipid, triglyceride at doses of 200 mg/kg, and $\beta$-sitosterol significantly exerted anti-hyperlipidemic activity at a dose of 15 mg/kg in rats with hyperlipidemia. Taken together, Brassica rapa L. and $\beta$-sitosterol can be useful agents for the prevention or treatment of hyperlipidemia.

  • A teratogenicity test of 'folpet' was carried out in the developing chick embryos to investigate and validate the safety of rural environmental hazardous materials. Folpet was administered to chick embryos' yolk sac at a rate of 0.1mg and 0.01mg per SPF eggs at 96 hours of incubation. The morphological changes were examined. Fertility ratio of SPF eggs used was 94.9%. Hatching rate of untreated control group was 74.4% and the group dosed with 100ul of corn oil into the yolk sac was 70.0%. The $LD_{50}$ of folpet was 0.663mg/100ul/egg. After hatching, mean body weight, body length, claw length and beak length of high and low dose administered groups were not significantly different from untreated and vehicle control group. There was no abnormal appearence in all the groups. Therefore it seems that, within the doses applied, folpet dose not induce potential teratogenicity in the developing chick embryos.
