Toxic hepatitis is a rare but devastating disease in children. Herbs are widely used in oriental medicine to treat various symptoms in Korea, however, several herbs have been reported to induce liver injury. We report a case of toxic hepatitis induced by Hovenia dulcis in a 3-year-old boy. He complained of nausea, abdominal discomfort, and jaundice. The patient had consumed water boiled with hovenia dulcis for about 1 year prior to presentation. A diagnosis of toxic hepatitis was made based on his history, laboratory data, viral markers, ultrasonography, and biopsied liver tissue. We administered supportive management for acute fulminant hepatitis but his symptoms and liver function progressed. He was transferred to another hospital for further evaluation and consideration for liver transplantation. Because acute liver failure due to herbs or dietary supplement taken for a long time is often fetal, it is important to make early diagnosis and stop taking the drug as soon as drug induced liver injury is suspected.

The objective of this experiment was to determine the effects of different levels of refined cod liver oil (RCLO) on laying performance, n-3 polyunsaturated fatty acids composition (n-3 PUFAs) and the organoleptic evaluation of duck egg yolks. A total of 180 30 wk old laying Tsaiya ducks, at the beginning of peak production, were allotted into 6 treatments with 3 replicates each. Ducks were fed one of the 6 experimental diets, supplemented with 2% tallow (control) and graded levels of RCLO at 2, 3, 4, 5, and 6% to a corn-soybean diets, respectively, for 6 wks. All of the experimental diets were formulated to be both isocaloric and isonitrogenous. Feed and water were supplied ad libitum throughout the experimental period. The results indicated that the RCLO supplementation levels did not affect (p>0.05) egg production, egg mass, feed intake, feed efficiency or body weight change. Egg weight was the lightest when the ducks received the 6% RCLO diet. The eicosapentaenoic acid, docosahexaenoic acid, and total n-3 PUFAs contents in the yolks increased with increasing RCLO supplementation. The taste and general acceptability of the hard-boiled eggs were not significantly different among the treatments. However, a fishy flavor was much higher when ducks were fed diets supplemented with 5% and 6% RCLO diets.

A practical and convenient method of rearing Eucyclops serrulatus in a microculture environment is described. A complete life cycle of E. serrulatus was maintained in a narrow space on a microscope slide glass on which a cover glass of $22{\times}40mm$ in size was mounted at a height of 0.8mm. The culture medium was constituted by bottled mineral water boiled with grains of Glycine max (soybean). Chilomonas paramecium, a free-living protozoan organism, was provided as live food. Growth of nauplii hatched from eggs to the first stage of copepodite took an average of 7.7 days, and the growth of copepodite 1 to the egg-bearing adult female took an average of 20.1 days in the microculture cell with an average life time of 44.7 days. Continuous passage of cope pods was successfully maintained as long as sufficient medium and food were provided. The microculture method enables an in situ microscopic observation on the growth and developmental process of helminth larvae experimentally infected to copepods as well as of copepod itself. Furthermore, it does not require anesthetization and, therefore, minimize the amount of stress exposed to cope pods during the handling process.

Preferences of 814 elderly living in Incheon for dishes, food materials and cooking methods were investigated. The survey was conducted from Dec. 2000 to Jan. 2001 by questionnaires. Subjects preferred cooked rice with beans, kalkooksoo(hot noodle), gomtang(soup with beef), bibimbap(rice with assorted mixture) to other staple dishes. However, preference for hashed rice or curried rice was very low. More than 50% of the subjects liked soybean paste soup and stew, and the ratio of elderly who liked Chinese cabbage kimchi was 68.7%. There was no significant difference in preference for pan-fried foods according to food materials in them. Subjects liked injolmi(waxy rice cake), shikhye(fermented rice drink) and coffee the most. Most subjects preferred plant foods like vegetables, legumes and seaweeds to animal foods. Preference of elderly for milk and yoghurt was reatively high; however, that for ham, butter and cheese was low. Elderly in Incheon liked roasted beef, beef soup and roasted pork the most. Chicken was preferred when it was boiled in water with garlic, ginseng, and so on. Cooked and seasoned vegetables (Namul) were the most preferred type by elderly. Preferences for dishes and food materials were more affected by living places of the subjects than by sex, and the reverse was true in preference for cooking method of food materials.

Objecitves: Peel of Citrus unshiu (Rutaceae) has been used in traditional herbal prescriptions. Hesperidin and naringin contents of Citri Unshii Pericarpium were determined and compared to herbal prescriptions. Then, the different extractions from prescriptions are explained with traditional herbal theories. Methods: The herb and herbal prescriptions were extracted in boiled water. A quantitative analysis was made of hesperidin and naringin using HPLC with-reversed-phase CIS column and a UV detector at 204nm. Elution was carried out at 1.0ml/min with $38\%$ methanol. Results and Conclusions: The extract of Citri Unshii Pericarpium for 180 min was the better method for extracting naringin and hesperidin. The flavonoid contents in remedies are different among several traditional herbal prescriptions. The reason for the difference can be explained with traditional drug interaction theories.

The Guk was divided Malgunjangguk, Tojangguk, and Gooumguk as to cooking method. Gooumguk was boiled with several materials of beef, bone, organs and water for the long time, and a good source of protein, calcium, and phosphorus. In the thesis, according to the kinds of Gooumguk, the reference frequency to them, the adding foods in them, and the variety cooking method in the Gooumguk were analyzed by the cooking books published from 1670 to 1988 in Korea. 1. There were 41 kinds of Gooumguk and Kaejang, Joktang and Byultang were firstly published to Omshikdimibang in 1670. 2. Many kinds of Gooumguk were generally used on royal parties in Yi dynasty and were used by several substances. 3. The main substances of Gooumguk were meat, poultry, fish, and shellfish. The seasoning substances were green onion, garlic, ginger and black pepper etc, and were used for the removal of the meat's or fish's off-flavor. 4. Yangtang, Kalbitang, Joktang, Yeongebacksuk, and Chooatang etc expressed the taste of the one main substance and Japtang, Sulnongtang, Yukgejang, Yongbongtang etc were combinated the taste of the several materials. 5. Cooking methods of Yukgaejang and Koritang before 19 century were different in present.: Yukgaejang was not used Gochoojang or powdered red pepper and Koritang was used Gochoojang.

The purpose of this study was to compare the effects of soup temperature on hunger, energy, and nutrient intake. The hot meal consisted of 400 g of hot beef-vegetable soup (75$^{\circ}C$), Yubu Chobap, Bulgogi, cucumber pickle and radish pickle. The cold meal component were the same as the hot meal except 300 g of water (8$^{\circ}C$) and boiled vegctables (100 g), instead of the hot beef-vegetable soup ot the hot meal. Thirst, core temperature and blood pressure were also measured before and after consumption the test meals in a within-subjects, repeated measures design. 30 women consumed 17% more kilocalories, 13% more protein and lipid and 16% more carbohydrate in the cold meal than in the hot meal. The core temperature at the end of the test meal was higher in the hot meal than in the cold meal. Energy and nutrient intake were inversely correlated with the hunger scores within 1 hour after the hot meal, however those are not related with each other in the cold meal. So hunger feeling might be disturbed in the cold meal. It is concluded that energy and nutrient consumptions were higher in the cold meal, partly because of the distrubed hunger feeling in the cold meal.

The brown seaweed Ecklonia cava is known to be a rich source of phlorotannins that have diverse biological activities. Among the phlorotannins in E. cava, concentrations of dieckol and phlorofucofuroeckol-A, which were identified as major active components, were determined in different parts of the tissue. We compared the efficacy of different pretreatments for their extraction. A high-performance liquid chromatography (HPLC) method to determine phlorotannin concentrations showed good accuracy (92.64 and 94.02%, respectively), precision (3.92 and 3.94%, respectively), and linearity (r>0.996). Mature thalli contained 1.5-fold more dieckol (1.82 mg/g-dry tissue) than young thalli. In the tissues of E. cava, blade tissue contained more phlorotannins than the stipe or holdfast. Among differently dried thalli, approximately 90% or more dieckol and phlorofucofuroeckol-A were extracted from shadow-dried tissue as compared with lyophilized tissue. In sun-dried and oven-dried thalli, approximately 60% of the phlorotannins were extracted. Thalli washed with fresh water, boiled thalli, and steamed thalli showed reduced extraction of the compounds.

This paper is intended to survey the literature about Shamanistic and Buddhistic memorial services and to examine the food culture manifested in them. In Shamanistic rituals, fish and meat were not prohibited except in special cases whereas Buddhism Prohibited fish and meat. For Shamanistic rituals, rice cake, cooked rice, liquor and the walleye pollack were commonly used. Besides there were such important offerings as a boiled pork head, chestnuts, jujube and persimmons (dried persimmons) . For Buddhistic memorial services, such foods as cooked rice, soup, cooked pot-herbs, saute, rice cake, confectionary (or candies), chestnuts and jujubes, were dedicated such offerings as cooked rice, rice cake, cooked pot-herbs and fruits were commonly used for both Shamanistic and Buddhistic memorial rites. Particular fruits were not prohibited in either case. Buddhistic rites in particular offered such foreign fruits as pineapples, kiwi and oranges, which showed that the foods of Buddhistic memorial services reflected the popular foods of the day more than those of Shamanistic ones. Water (Jung-hwa-su) brought from the well at daybreak for Buddistic memorial rites came from Shamanism, where as oil-and-honey pastry (Yu-gwa) used for Shamanistic rites came from Buddhism, which showed that the offerings of Buddhistic memorial services and Shamanistic ones were influenced by each other.

Bioactivity of the extract from various processed garlic was evaluated based on the inhibition of lipoxygenase(LPO), and the effect of some stabilizers on the bioactivity was investigated. Water, ethanol or chloroform extract of 30 min boiled garlic showed 75%, 76% or 70% inhibition, respectively, compared to extracts of fresh garlic. In pickled garlic, LPO inhibition decreased gradually during storage. Chloroform extract of 40 day-stored pickled garlic inhibited LPO by 77%, and even on 60th day storage it still retained inhibitory effect of 73%, compared to that of fresh garlic. Meanwhile, the powdered (freeze-dried) garlic showed more bioactivity(80%) than the other processed garlics, and moreover, the jrreversible/unstable components seem to be stabilized by freeze-drying. The optimum pH for stabilization of bioactive components in garlic macerate was pH 3 for 48 hr incubation and pH 11 for 6 hr incubation. In addition, the effect of NaCl was not so great, although but maximal stabilization was observed at 150 mM. Stabilizing effect of $\alpha$-tocopherol was markedly great, and at 6mM it showed 308% stabilizing effect after 48hr incubation. More stabilizing effect was observed at lower concentrations of ascorbic acid($\leq$0.6mM) than higher concentrations. The stabilizing effect of soybean oil was found to be remarkable only during initial period(6 hr) of incubation.
