In order to design and develop a product that can treat the fatty liver, natural complex food with all natural ingredients was developed and supplemented to rats with high fat diet to induce fatty liver. As a result, when the amount of natural complex food was increased in diet of subjects, the activities of the blood serum AST, ALT, ALP, 3-GT and LDH were decreased. The total protein concentration levels of the 30% and the 50% natural complex food groups did not show changes in respect to the control group, but the 100% natural complex food groups showed significant decrease (p<0.05). Likewise, the amount of blood serum albumin in the 30% and the 50% natural complex food groups did not show improvement, but the 100% natural complex food did showed significant changes (p<0.05). The amount of blood serum triglyceride decreased as the amount of natural complex food was increased. In order to investigate the appearances of the accumulated fat in the liver, the animals were dissected. Livers of the control group (no natural complex food) were appeared as a white color, which means serious fat accumulation. However, all the natural complex food groups (30,50 and 100% natural complex food) showed noticeable decrease of fat content. Even the histology showed that livers of the control group had expansion of the fat, but a11 the natural complex food groups had e decreased as the contents and continued to show destroyed fatty cells. By observing the biological numeric data, the physical appearance and the history of the fatty liver, it is highly expected that natural complex food is very effective in treating the liver damaged -by the to fat and the cholesterol.

The purpose of this study was to investigate the effects of nine times repetitive steaming and drying process Sunsik diets on antioxidant activity in obese mice fed high fat diets to prevent oxidative stress, using drying materials comprising 23 kinds of cereals (61.5%), beans (30.0%), sweet potato and potato (3.0%), fruits (2.0%), vegetables (3.0%), and stevioside, a natural sweetener (0.5%). We produced three samples: the experimental group was classified into the normal diet group (control), the high fat diet group (HF), and the high fat diet group + the Sunsik group (3HFS, 7HFS, 9HFS) fed to the mice for eight weeks. As a result, the serum, liver lipid peroxide, and nitric oxide levels were significantly higher in the HF group than in the C group at p<0.05 level, and the NO level was lower in the Sunsik supplemented groups. The antioxidant enzyme catalase activity significantly decreased in the HF group at the p<0.05 level compared to the C group. The total antioxidant activity of the C group was significantly higher in serum, liver, and kidney tissues than the HF group (p<0.05). The anthocyanin level in liver and spleen tissue was significantly higher in the group fed Sunsik than in the HF group.

To understand the diet of chaetognaths, the gut content and fatty acid trophic makers (FATMs) of Sagitta crassa and S. nagae, which are the most predominant species of chaetognath in the Yellow Sea, were analyzed. Gut contents of the two species examined by microscopic analysis revealed that copepods are the major components of the diet (> 70% of gut contents) and there was no significant changes in the gut contents of two species collected in spring and summer season. Although 16:0, 20:5(n-3) (Eicosapentaenoic acid) and 22:6(n-3) (Docosahexanoic acid), which are known as phytoplankton FA markers, were the most dominant among the fatty acids in both chaetognath species, the detection of copepod FA markers, 20:1(n-9) (Gadoleic acid) and 22:1(n-11) (Cetoleic acid), provided evidence that their food sources include copepods. These results suggest that S. crassa and S. nagae are carnivores and mainly feed on copepods in the Yellow Sea.

Sense-line (SL), a dietary functional food, is our invention for weight loss. To evaluate such an effect of SL, we analyzed the plasma levels of total cholesterol, low-density lipoprotein (LDL) cholesterol, high-density lipoprotein (HDL) cholesterol, and weight changes after rats were fed on high fat diet with SL for 20 days. Plasma total cholesterol level and LDL-cholesterol level was decreased by 52% and 91.89% in 5% SL treated group and by 13% and 51.45% in 10% SL treated group, respectively. But HDL-cholesterol was not changed. In addition, the weight was significantly lower in SL group than in high-fat diet group (P<0.05). Our findings indicate that SL may contain compounds with actions, which can treat blood circulatory trouble as well as overweight.

Salmon oil (SO) could be used as a great source of ω-3 fatty acids in pig diet. The purpose of the study was to investigate the SO effect on production performance of sows and their offspring. 48 lactating sows (Landrace × Yorkshire) from Dankook University experimental farm were used in this study. Sows were conceived using either guided natural mating or by artificial insemination. Pregnancy diagnosis was confirmed by ultrasonography on day 25 after mating. Sows and their offspring were assigned randomly to 1 of 2 treatments. Treatments included: 1), control (CON); 2), control + SO 0.5% (CS). The inclusion of SO did not affect (p > 0.05) the litter size throughout the experiment. No difference (p > 0.05) was observed on the average daily feed intake (ADFI), chest circumference, estrus interval and sow backfat thickness between CON and SO treatments. Dietary SO supplemented diet reduced (p < 0.05) body weight loss during lactation compared with control treatment. Pigs fed SO supplemented diet did not affect (p > 0.05) the fecal scores during lactation compared with those fed control treatments. Sows fed SO supplemented diet led to a higher (p < 0.05) initial weight, weaning weight and average daily gain of piglets than those fed control diets. No difference (p > 0.05) was observed on piglet survival and fecal scores throughout the experiment. Inclusion of SO could reduce the body weight loss of sows and improves piglet growth during lactation, indicating SO has beneficial effects for pigs.

Purpose: The objective of this study was to examine whether Hamcho freeze-dried powder and Hamcho freeze-dried nano powder have an anti-obese effect on high fat diet-induced obese rats. Methods: Sprague Dawley rats were divided into 6 different groups, each of which was bred for 8 weeks with a different experimental diet: normal diet group (NC), high fat diet group (HFC), high fat diet + 2% Salicornia herbacea L. freeze-dried powder group (2% HS), high fat diet + 5% Salicornia herbacea L. freeze-dried powder group (5%HS), high fat diet + 1% Salicornia herbacea L. freeze-dried nano powder group (1% HSN), high fat diet + 2% Salicornia herbacea L. freeze-dried nano powder group (2% HSN). Results: The 5% HS group showed a weight loss effect in body weight, liver and adipose tissue by reducing the amount of dietary intake and food efficiency ratio. In addition, the 5% HS group showed a significant reduction of serum leptin concentration, while having a beneficial effect on the improvement of lipid metabolism such as increase the serum concentration of adiponectin. However, Hamcho freeze-dried nano powder did not show a weight loss effect. Conclusion: Overall data indicated that Hamcho seemed to have anti-obesity effects. In particular, consumption of 5% Hamcho freeze-dried powder might have beneficial effects on body weight, serum adiponectin level, and lipid profiles since it led to reduced body weight and growth of adipose tissues by suppressing dietary intakes. However conduct of further research studies is needed for analysis of active components and biochemical action mechanism of Hamcho.

A 15-week feeding trial was conducted to investigate the effect of formulated diet or macroalgae (Undaria pinnatifida) on the survival, growth and body composition of juvenile abalone (Haliotis discus hannai) under the different rearing environmental conditions (four shelter types and two water temperatures). Water temperature was maintained to $16.4^{\circ}C$ by heated and $13.7^{\circ}C$ by not heated natural sea water. The survival rate, weight gain and shell growth of abalone were affected by diet and water temperature (P<0.001). Survival rate of abalone fed the formulated diets was higher than that of abalone fed the Undaria pinnatifida at natural sea water (P<0.05), but this value was not influenced within abalone stocked at heated sea water in each shelter group (P>0.05). Weight and shell growth of abalone fed the formulated diets were significantly higher than those of abalone fed the Undaria pinnatifida at each temperature or shelter (P<0.05). Moisture, lipid and ash contents of the soft body were mainly affected by feeding diet than temperature or shelter (P<0.05). This study indicate that formulated diet used in this experiment could improve the growth of abalone independent of water temperature or shelter. and heated water could show a better growth of abalone in winter season.
