Objectives : This study investigated the improvement effects of Pakistani (DF-a) and Chinese Ephedra herba-containing Gangjihwan (DF-b) on nonalcoholic fatty liver disease in a high fat diet-induced obese mouse model. Methods : Eight-week-old C57BL/6N mice were divided into five groups: a normal lean group given a standard diet, an obese control group given a high fat diet, and atorvastatin, DF-a, and DF-b groups given a high fat diet with atorvastatin (10 mg/kg), DF-a (80 mg/kg), and DF-b (80 mg/kg), respectively. After 8 weeks of treatment, body weight gain, blood lipid markers, ALT concentrations, liver weight and histology were examined. Results : 1. Body weight gain was significantly decreased in DF-a, DF-b, and atorvastatin groups compared with control. The extent of decreases was eminent in DF-a group. 2. Circulating concentrations of total cholesterol and LDL-cholesterol were significantly decreased in DF-a, DF-b, and atorvastatin groups compared with control. The decreases were most effective in atorvastatin group. 3. Liver weights were decreased in DF-a, DF-b, and atorvastatin groups compared with control. In particular, liver weight was significantly reduced in DF-b group. 4. Hepatic lipid accumulation was significantly decreased in DF-a, DF-b, and atorvastatin groups compared with control, and the magnitude of which was most effective in DF-b group. 5. Circulating ALT concentrations were decreased in DF-a, DF-b, and atorvastatin groups compared with control, but ALS levels were significantly reduced only in DF-b group. Conclusions : In conclusion, these results suggest that DF-a and DF-b decrease body weight gain, improve blood lipid metabolism, and reduce liver weight and hepatic lipid accumulation, contributing to the improvement of nonalcoholic fatty liver disease. In addition, these effects were similar between Pakistani and Chinese Ephedra herba-containing Gangjihwan.

Objectives: There is a steady increase in the prevalence of obesity worldwide and obesity is often accompanied by inflammation. Although much emphasis has been placed on the adipose tissue inflammation in obesity, a study with herbal medicine is few. This study aimed to investigate the antidiabetic and anti-inflammatory effect of a complex herbal medicine (CHM) composed of Cornus officinalis, Dioscorea rhizoma, Aurantii fructus, and Mori Foliumon on obese type 2 diabetes mice. Methods: Type 2 diabetes mellitus and obesity were induced by Surwit's high fat, high sucrose diet for 8 weeks. Mice were divided into ND (normal diet, n=10), HFD (high fat and high sucrose diet, n=10), CHM (high fat and high sucrose diet with complex herbal medicine, n=10) and Met (high fat and high sucrose diet with metformin, n=10) groups. The body weight, fructosamine and OGTT (oral glucose tolerance test) were measured. After 8 weeks the blood samples of all mice were taken from the heart, and lipid profiles were measured. Epididymal fat pad, histological size of the adipocyte tissue and liver weights were measured. Inflammatory markers such as leptin and adipocyte tissue macrophage were measured to evaluate the effect of CHM on adipocyte tissue inflammation. Results: Compared with the HFD group, there was an improvement in OGTT and epididymal fat decreased in the CHM group. White adipocyte size and adipocyte tissue macrophage decreased in CHM group. Conclusions: These results suggest that CHM has antidiabetic and anti-inflammatory effects in high fat, high sucrose diet induced obese mice.

Background: Although soybean meal (SBM) is excellent source of protein in diets for poultry, it is sometimes inaccessible, costly and fluctuates in supply. The SBM can partially be replaced by full-fat SBM, but the meals prepared from raw full-fat soybean contain antinutritional factors. To avoid the risk of antinutritional factors, heat treatment is always advisable, but either excessive or under heating the soybean could negatively affect the quality. However, the potential for further improvement of SBM by supplementing with microbial enzymes has been suggested by many researchers. The objective of this study was to evaluate the performance and ileal nutrient digestibility of birds fed on diets containing raw soybeans and supplemented with microbial protease. Methods: A $3{\times}2$ factorial, involving 3 levels of raw full-fat soybean (RFFS; 0, 45 or 75 g/kg of diet) and 2 levels of protease (0 or 15,000 PROT/kg) was used. The birds were raised in a climate-controlled room. A nitrogen-free diet was also offered to a reference group from day 19 to 24 to determine protein and amino acid flow at the terminal ileum and calculate the standardized ileal digestibility of nutrients. On days 10, 24 and 35, body weight and feed leftover were recorded to calculate the body weight gain (BWG), feed intake (FI) and feed conversion ratio (FCR). On day 24, samples of ileal digesta were collected at least from two birds per replicate. Results: When RFFS was increased from 0 to 75 g/kg of diet, the content of trypsin inhibitors was increased from 1747 to 10,193 trypsin inhibitors unit (TIU)/g of diets, and feed consumption of birds was also reduced (P < 0.05). Increasing RFFS level reduced the BWG from hatch 0 to 10 d (P < 0.01) and hatch to 24 d (P < 0.05). The BWG of birds from hatch to 35 was not significantly (P = 0.07) affected. Feed intake was also reduced (P < 0.05) during 0 to 35 d. However, protease supplementation improved (P < 0.05) the BWG and FCR during 0 to 24 d. Rising levels of RFFS increased the weight of pancreas (P < 0.001) and small intestine (P < 0.001) at day 24. Except for methionine, apparent and the corresponding standardized ileal digestibility of CP and AA were reduced (P < 0.01) by increasing levels of RFFS in diets. Conclusion: This study showed that some commercial SBM could be replaced by RFFS in broiler diets, without markedly compromising productivity. The AID and SID of CP and lysine were slightly improved by dietary supplementation of microbial protease.

In this study, the effect of complex hot water extracts of Cirsium jaonicum, Artemisia annua and Curcuma longa (CAC) on the improvement of non-alcoholic fatty liver disease (NAFLD) was investigated. CAC inhibited fatty acid synthesis and lipid accumulation in HepG2 cells cultured with free fatty acid (FFA). In the NAFLD animal model, CAC extract suppressed the increase in body weight, liver, and epididymis fat weight, and suppressed the increase in hepatocyte fat and blood triglyceride. In addition, by blocking the Nrf2/HO-1 signaling pathway, cells were protected from oxidative stress in hepatocytes. Moreover, CAC inhibited the expression of COX-2, iNOS, TNF-α and IL-17 in hepatocytes. These results suggest the possibility that CAC extract can be applied in the field of health functional foods and pharmaceuticals for improvement and prevention of NAFLD.

The identification method that inflects real time ultrasound (RUT) and the potential application of marker assisted selection (MAS) for improvement of a cow population of Hanwoo (Korean Native cattle) was studied. The averages of RUT longissimus muscle area, RUT fat thickness, and RUT marbling score scanned at the 13th rib were 55.78 $cm^2$, 3.70 mm and 3.83 scores, respectively. We investigated the effects of the two SNPs (Kpn2 I and Msp I) in the leptin gene on carcass traits for Hanwoo cows by using ultrasound measurements. Genotype CC of the Kpn2 I had a significantly higher effect on back fat thickness (4.23 mm) and longissimus muscle area (57.57 $cm^2$) than genotype TT (3.14 mm, 53.93 $cm^2$, respectively, p<0.05). Genotype AA of the Msp I had a significantly higher effect only on marbling score (5.37) than genotype AB (3.57, p<0.05) and BB (3.37, p<0.05). Significant effects of SNPs in the leptin gene were found for the ultrasound measures of body composition in live cattle.

본 연구는 과체중 및 비만 또는 복부비만 성인을 대상으로 8주간 중강도 수준의 필라테스 운동 후 필라테스 운동의 순응도에 따른 신체조성, 균형능력 및 기초대사 지표의 변화를 확인하였고, 식생활습관 개선교육후 영양지수의 변화도 함께 살펴보았다. 필라테스 운동에 대한 순응도가 높은 군이 순응도가 낮은 군에 비해 신체의 균형도와 체구성에 더 긍정적인 변화를 보였고 더불어 혈관노화지수도 유의적으로 개선되었고 공복혈당과 당화혈색소가 유의적으로 개선되었다. 그러나 필라테스 운동에 대해 순응도가 낮은 군이라도 실시하지 않았던 것에 비해서 신체균형도, 체질량지수 및 피하지방 면적은 유의적으로 개선되었다. 이는 순응군과 비순응군 모두에서 영양지수가 개선된 것과, 순응도 여부에 관계없이 전체 대상자에서 식생활 교육 후에 하루 식사횟수, 아침식사횟수, 식사의 규칙성, 과식 및 외식횟수 등이 긍정적인 방향으로 변동된 것과 관련이 있을 것으로 판단된다. 따라서, 본 연구는 필라테스 운동과 식생활 개선교육을 포함한 전반적인 생활습관의 개선을 통해 과체중 이상의 여성에서 유의미한 개선 결과가 있음을 보여주고 있다. 더불어 식생활습관 개선 교육만으로도 어느정도 비만관련 지표의 개선에 영향을 줄 수 있을 것이며, 필라테스 운동을 함께 실시했을 때에는 그 개선 효과가 좀더 잘 관찰되는 것으로 판단된다.
