This study examined the effects of plums produced in Gimcheon area on the glucose and lipid metabolism in streptozotocin-induced diabetic rats. Male Sprague-Dawley diabetic rats were divided into four groups: control, diabetic control, Diabetes-low plum (containing 10% plum powder), and Diabetes-high plum (containing 20% plum powder). The animals were fed isocaloric experimental diets based on an AIN-76 diet for 6 weeks. Feed efficiency ratio (FER) of the diabetic groups were significantly lower than that of the control. On the other hand, among the diabetic groups, the FER of the high plum intake group was higher than that of the diabetic control. The liver weight per 100 g body weight of each group was similar but the liver weights tended to decrease as the amount of plum intake was increased. Kidney weight per 100 g body weight of the plum intake groups were significantly different compared to that of the diabetic control. The supplementation of plums lowered the fasting blood glucose level of the diabetic groups and improved the glucose tolerance, thereby lowering the glycosylated hemoglobin index. In addition, the supplementation of plum was lowered the blood total cholesterol concentration and increased the HDL-C/TC (%) significantly, thereby lowering the atherosclerotic index (AI) and hepatic peroxide level. A steady diet of plums produced in Gimcheon may be effective in controlling the blood glucose level and preventing chronic diabetes mellitus.

Objectives : In this study, the inhibitory activities of Korean Medicine against pancreatic lipase in vitro and biochemical analyses in vivo were measured to determine its possibility as a well-matched sauce material with chicken. Methods : The inhibitory activity on pancreatic lipase enzyme of 11 samples were evaluated in vitro and then 5 samples were selected. The activity of pancreatic lipase was investigated using orlistat as a positive control. Animals were divided into eight groups (n=7). The experimental groups except for normal group were fed 60% high-fat diet for 7 days. 5 samples were orally administered at a dose of 200 mg/kg body weight and orlistat were orally administrated at a dose of 60 mg/kg body weight for 7 days. Biochemical anaylses of 5 samples were executed based on lipid parameters analysis. Results : Korean Medicines with an $IC_{50}$ of below 1 mg/kg were Scutellariae Radix, Gardeniae Fructus, Theae Folium Coptidis Radix, and Mori Cortex Radicis. Body weight change of Mori Cortex Radicis reduced significantly, however fecal triglyceride couldn't regulate effectively. The most excellent inhibitory effect of pancreatic lipase showed in Scutellariae Radix treatment and also regulated significantly serum triglyceride and total cholesterol. Moreover, the supplementation of Coptidis Radix excreted meaningfully triglyceride to fece. Conclusions : In conclusion, Coptidis Radix may exert anti-obesity effect by directly inhibiting pancreatic lipase, which would prevent the absorption of lipid from the small intestine. Besides, Mori Cortex Radicis may led to the decrease of the body weight via the different pathway.

Pine needles are known as a traditional medicine and their ingestion has been shown to be beneficial to human beings. Following induction of the neoplastic process in rats by azoxymethane (AOM), we determined the effects of pine needle supplementation on colon carcinogenesis and on antioxidant systems in the blood and liver. Five week old male Fisher 344 rats were injected with AOM (15 mg/kg) once a week for two weeks. After the second injection, 18 rats were randomly assigned into two groups and were fed a casein-based high-fat diet (120 g fat and 1 g cholesterol/kg diet) with or without pine needle powder (10%w/w). After 6 weeks, rats receiving pine needle powder showed a 40% lower incidence of the number of colonic preneoplastic lesions (aberrant crypts) and a 52% lower incidence of aberrant crypt foci (p<0.01). A significantly elevated level of erythrocyte catalase activity was observed in the pine needle supplemented group (17.4$\pm$1.1 vs. 24.5$\pm$1.5, p<0.01). Pine needle supplementation also increased liver glutathione peroxidase activity (7.5$\pm$0.6 vs. 14.6$\pm$0.6, p<0.01). Other antioxidant parameters such as erythrocyte glutathione peroxidase, liver catalase activity, and plasma total antioxidant potential (TRAP), showed no statistical differences between the two groups. Our data demonstrate that pine needle supplementation improves the antioxidant system and suppresses the formation of colonic preneoplastic lesions in AOM-treated rats. This result provides additional insights into the chemo-preventative properties of pine needles.

Saururus chinensis Baill was reported to inhibit ${\alpha}-glucosidase$ in vitro and flatten postprandial increase in blood glucose in streptozotocin (STZ)-induced diabetic rats. We studied the effect of chronic consumption of S. chinensis Baill on blood glucose and lipid profile in STZ-induced diabetic male rats fed high fat diet. Male rats weighing 100-120 g were fed 30% fat diet with and without 10% freeze-dried leaves of S. chinensis Baill for 7 weeks after 1 week of adaptation. The rats were rendered diabetic by intravenous injection of STZ (60 mg/kg) after 6-week feeding of the assigned diets. At 1 week after the injection, the rats were sacrificed after an overnight fast. Plasma glucose ($380.2{\pm}14.4mg/dL$), total cholesterol ($93.9{\pm}7.9mg/dL$) and triglyceride levels ($123.6{\pm}7.5mg/dL$) of the S. chinensis Baill group were significantly lower than those of the control group ($418.1{\pm}12.0mg/dL,\;119.9{\pm}9.4mg/dL,\;152.0{\pm}10.3mg/dL$, respectively, p<0.05). Chronic consumption of S. chinesis Baill significantly decreased maltase activity of the small intestinal mucosa ($120.1{\pm}8.7U/g$) protein compared with the control group ($96.8{\pm}7.0U/g protein, p<0.05). These results suggest that S. chinensis Baill have hypoglycemic and hypolipidemic effects by inhibiting ${\alpha}-glucosidase$ activity in the animal model of diabetes mellitus.

In this study, we investigated the anti-obesity effects of various mixtures of Atractylodes macrocephala (AM) and Amomum villosum (AV) water extracts on high-fat diet (HFD) induced mouse model. We classified five groups as follows; control, HFD, HFD + AM extracts : AV extracts (100mg/kg) (1:1), HFD + AM extracts : AV extracts (100mg/kg) (2:1), HFD + AM extracts : AV extracts (100mg/kg) (3:1). Oral administration of various mixtures of AM and AV extracts for 6 weeks inhibited HFD-induced increases of body, liver and epididymal fat weights. Also, lipid profiles including LDL cholesterol were improved by various mixtures of AM and AV extracts treatment compared with HFD-fed group. Lipogenesis-related genes such as acetyl coA carboxylase (ACC) and fatty acid synthase (FAS) in liver changed in a favorable way for lipid biosynthesis by HFD compared to control, but various mixtures of AM and AV extracts-treated groups did not. Our results show that various mixtures of AM and AV extracts can prevent HFD-induced obesity in mice and suggests that the mechanisms are involved in expressions and modifications of lipogenesis-related genes such as ACC and FAS in liver.

Effects of alpha-galactosidase (GAL) on broiler corn-soybean meal diet was investigated. In experiment 1, sixty cockerels were allocated to five groups, including three enzyme treatments (GAL added at 0, 500, and 1,000 mg/kg diet), a nitrogen-free diet group and a fast group. The true nitrogen-corrected ME (TME$_n$) and true amino acid availability were determined. In experiment 2, 324 day-old chicks were used in a 2${\times}$3 factorial design consisting of two energy contents (high and low) and three GAL levels (0, 250, and 500 mg/kg). Three feeding phases, comprising 0-21 d, 22-35 d and 36-48 d, were involved. GAL addition improved TME$_n$ and the availability of methionine and cystine (p<0.05). The apparent ME (AME) or nitrogen-corrected AME (AME$_n$) and digestibility of dry matter, organic matter, calcium, and phosphorus were improved significantly on d 21, so was crude protein and an interaction of energy and GAL on AME$_n$ (p<0.05) was found on d 35. However, daily intake and daily gain were significantly improved with GAL addition (p<0.05) during 21 d. The small intestine relative weight decreased at 250 mg/kg GAL (p<0.05) on d 35, whereas presented an interaction between GAL and energy on d 21 (p<0.05). Likewise, this treatment increased breast muscle ratio (p<0.05). On d 21, triglycerides level of broilers showed interaction between energy and enzyme levels (p<0.05). Uric acid level in 500 mg/kg GAL declined linearly (p<0.05). On d 35, quadratic effects (p<0.05) were observed in total protein, albumin, globulin and cholesterol content for enzyme supplementation. And the interactive effects of energy and GAL on serum values showed more obviously. The study implies that GAL improved energy and nutrient availability of corn-soybean meal diet in broiler. The GAL supplementation to corn-soybean meal based diet can improve performance of broilers in early stages of growth.

본 연구에서 우리는 고지방식이로 유도된 비만 마우스의 몸무게, 장기 무게, 부고환 지방조직 무게, 부고환 지방조직의 지방세포 크기 및 혈장 지질 농도가 E. faecalis MD366 균주의 투여로 어떤 영향을 미치는지 연구하였다. E. faecalis MD366균주의 항비만 효과를 알아보기 위하여 C57BL/6J 마우스를 정상식이군(ND), 고지방식이군(HFD), 고지방식이와 함께 E. faecalis MD366 균주를 경구투여한 군(HFD+MD366)으로 나누어 6주 동안 실험을 진행하였다. 6주 후 무게는 ND, HFD+MD366, HFD군 순으로 높게 나타났으며, 초기 무게 대비 체중 증가율은 HFD+MD366군이 HFD군에 비해 18.10% 감소하였다. 간과 신장, 고환의 장기조직 무게는 세 군 모두 비슷하였으며, 부고환 지방의 평균무게의 경우 ND군이 가장 작았으며, HFD+MD366군은 HFD군 보다 작게 나타났지만 유의적 차이는 보이지 않았다. E. faecalis MD366의 투여가 혈청 지질 농도에 미치는 영향을 본 결과, TG의 농도는 HFD+MD366군이 HFD군에 비해 감소하기는 했지만 유의적 차이는 없었으며, 총 콜레스테롤과 LDL-콜레스테롤 수치에 있어서도 HFD+MD366군이 HFD군에 비해 평균적으로 적은 수치를 나타내었으나, 유의적 차이는 보이지 않았다. 부고환 지방세포 크기의 분포를 본 결과 ND와 HFD+MD366군은 $2,000{\mu}m^2$ 크기의 지방세포가 가장 많이 분포하였고, HFD군에서는 $5,000{\mu}m^2$ 이상 크기의 지방세포가 가장 많이 분포하였으며, 지방 세포의 평균 크기는 ND, HFD+MD366, HFD 순으로 큰 것으로 나타났다. 비록 체중과 장기, 지방 무게와 혈청 지질농도 수치에는 E. faecalis MD366 균주가 큰 효과를 보이지 못했지만 부고환 지방세포 형성 및 지방세포 크기 증가를 저해함으로써 항비만 효과가 있을 것으로 사료된다.
