본 연구는 만성 알코올 유도 쥐에 대한 1.5% 헛개나무 열매 농축액이 첨가된 콩나물 혼합물의 숙취해소 및 간 기능 개선 효과를 확인하고자 하였다. 헛개나무 열매 농축액을 함유한 콩나물 혼합물군(SHM) 내 ampelopsin 및 L-asparagine의 함량은 10.52, 35.19 ppm으로 확인되었으며, 만성 알코올 급여에 의해 체중 변화량이 감소하고, 간 중량은 증가한 반면 SHM 처리시 유의적으로 체중 변화량이 증가하였으며, 간 중량이 감소하였다. 혈중 alcohol 및 acetaldehyde의 농도는 SHM군에서 2.89, 0.53 g/L로 가장 낮은 함량을 보였으며, 간 조직 ADH 및 ALDH의 활성은 SHM군에서 33.11, 102.06 U/L로 가장 높은 활성을 나타냈다. 만성 알코올 유도는 ALT, AST 및 GGT와 같은 간 기능 지표 효소들의 활성을 증가시켰지만, SHM 처리시 각각 41.00, 130.83 및 0.47 U/L로 활성이 유의적으로 감소하였다. 간 조직 및 혈중 triglyceride 함량은 SHM군에서 1.45와 33.00 mmol/L로 가장 낮은 값으로 나타났고, 만성 알코올 투여로 증가된 혈중 total cholesterol 및 LDL cholesterol 함량은 SHM에 의해 감소하였으며, 만성 알코올 투여로 인해 감소된 혈중 HDL cholesterol 함량은 SHM 처리시 증가하였다. 간 조직을 형태학적 및 병리학적으로 관찰한 결과, 만성 알코올 유도군의 간 조직은 형태학적 관찰에서 황갈색을 띠었고, 병리학적 관찰에서는 지질방울의 크기 및 수가 증가하였다. 그러나 SHM 처리시 형태학적으로 관찰한 간 조직의 색은 적갈색으로 나타났고, 병리학적으로 관찰한 간 조직의 지질방울 크기 및 수는 감소하였다. SHM군의 간 조직 및 혈중 지질 과산화 함량은 677.68, 76.26 nmol/g으로 가장 낮은 값으로 확인되었으며, 간 조직 및 혈중 GSH 함량은 SHM군에서 가장 높은 값인 19.93 및 20.08 μmol/kg으로 나타났다. 따라서 콩나물 또는 헛개나무 열매의 단일 섭취보다 혼합하였을 때 ampelopsin 및 asparagine과 같은 유효성분들의 시너지에 의해 SHM군에서 증진된 숙취해소 및 간 기능 개선 효과를 확인할 수 있었으며, 이는 기능성 식품 소재화에 대한 가능성을 제시하는 기초 자료로 활용될 수 있음을 시사한다.

Effects of Acanthopanax senticosus extract (AS) on blood sugar content and serum lipid profiles of streptozotocin-induced diabetic rats were investigated. Experimental groups were classified into four groups, that is, normal control (NC) group, diabetic mellitus (DM) group, AS-fed group and DMAS-fed group. The AS group showed lower feed efficiency than the NC group, but the efficiency of DMAS group was higher than DM group. DMAS group showed the decreased water intake and urine by $45.5\%$ and $23.7\%$ respectively, compared with DM group. Compared with DM group, DMAS group decreased blood sugar by $46.9\%$ and triglyceride by $17.8\%$, total cholesterol by $10.0\%$ and LDL cholesterol by $22.0\%$ in serum, but increased serum HDL cholesterol by $14.4\%$ The relative percentage of liver or kidney per body weight, and the serum ALT activity in DMAS group were lower than those of DM group. There were no significant differences in hepatic glutathione(GSH) contents and total xanthine oxidase(XOD) activities among experimental groups. The hepatic lipid peroxide(LPO) content in DMAS group decreased by $54.6\%$ compared with that in DM group. The XOD (O type) and the ratio of O type to total type of both STZ-treated groups (DM and DMAS) were higher than those of NC group, but less conversion of D to O type was observed in DMAS group than in DM group. There was no significant difference in GST activity between NC and AS, but STZ-treated groups showed lower glutathione S-transferase(GST) activity than NC. In conclusion, it seems that AS reduces blood sugar by inhibiting the activity of xanthine oxidase type O as an oxygen-free radical generating system which induces the tissue damage. Antidiabetic effect of AS may regulate diabetes-induced high lipid profiles in blood.

This study was carried out to investigate the effect of dietary supplementation of red ginseng by-product (RGB) on the laying performance, blood biochemistry, and microbial population in laying hens. A total of 120 Hy-Line Brown laying hens (75 weeks old) were randomly allotted to 1 of 3 dietary treatments with 4 replicates per treatment. A commercial-type basal diet was prepared, and 2 additional diets were prepared by supplementing 5.0 or 10.0 g/kg of RGB to the basal diet at the expense of corn. The diets were fed to hens on an ad libitum basis for 4 weeks. There were no differences in feed intake, egg weight, and feed conversion ratio during 4 weeks of the feeding trial. However, hen-day egg production was significantly greater (p<0.05) for the RGB treatment groups than that for the basal treatment group. There were no differences in triglyceride, aspartate aminotransferase, and alanine aminotransferase during the 4-week feeding trial. However, RGB supplementation increased (p<0.05) the serum immunoglobulin G (IgG) and IgM content compared with basal treatment group. The total cholesterol was lower (p<0.05) in the RGB treatments groups than that in the basal treatment group. The intestinal Lactobacillus population was greater (p<0.05) for the RGB treatments groups than that for the basal treatment group. However, the numbers of Salmonella and Escherichia coli were not different among dietary treatments. During the entire experiment, there was no significant difference in egg quality among all the treatments. In conclusion, in addition to improving hen-day production, there were positive effects of dietary RGB supplementation on serum immunoglobulin and cholesterol levels in laying hens.

This study was conducted to investigate the effect of late-harvested green tea extract on serum and tissue lipid contents and Ca absorption. Sprague-Dawley male rats weighing 200g were fed high fit diets containing no tea(control), 0.5%(0.5LG), 1.0% late-harvested green tea extract(1.0LG), and 1.0% early-harvested green tea extract(1.0EG) for 4 weeks. Though daily food intake of experimental groups showed no significant difference from that of control group, daily body weight gain and food efficiency ratio were lower in all groups fed green tea extract. The contents of serum triglyceride of 1.0LG and 1.0EG groups and the content of serum total cholesterol of 1.0LG group were significantly lower than those of control group. The values of serum HDL-cholesterol in groups fed green tea extract were higher than that in the control group. LDL-cholesterol and atherogenic indices of all groups fed green tea extract were significantly lower than those of the control group. The contents of total lipid and triglyceride in liver were significantly lower in only 1.0LG group. For epididymal fit pad, the contents of total lipid and triglyceride in 1.0LG and 1.0EG groups were lower than those in the control group. The contents of total lipid excreted in feces were higher in groups fed diets of 1.0% green tea extract. There was no significant difference among experimental groups in Ca absorption. These results suggest that the administration of late-harvested green tea extract decreases the contents of fat in the body without reducing Ca absorption.

This study was done to determine the effect of antioxidants added perilla oil diet on the content of cholesterol, vitamin E, and lipid peroxide in serum and tissue of rats. Four groups of experimental diets, such none added perilla oil diet, ascorbic acid added perilla oil diet, vitamin E added perilla oil diet, EDTA added perilla oil diet were fed ad libitum to the 4 weeks white male rats of Sprague-Dawley strain. The results obtained are summarized as follow: 1) The body weight gain in all experimental diet groups was higher than the control gorup and EDTA added diet group was lower than the other experimental diet group, while food intake in vitamin E added diet group was the highest and vitamin C added diet group was the lowest in the control group. 2) Total cholesterol levels in serum of all experimental diet groups were lower than that of the control group and especially the level of total cholesterol in none added diet group and vitamin C added diet group were significantly lower than that of control group. 3) HDL-cholesterol levels of all experimental diet groups were lower than that of the control group and especially none added diet group was significantly lower than that of control group. 4) The activities of glutamic oxaloacetic transaminase (GOT) in serum of all experimental diet group except EDTA added diet group were higher than that of the control group and especially none added diet group was significanly higher than that of the control group. The activites of glutamic pyruvic transaminase (GPT) in serum of all experimental diet groups except vitamin C added group were higher than that of control group. 5) Vitamin E levels in serum of none added diet group and vitamin C added diet group were lower than that of the control group and vitamin E added diet group and EDTA added diet group were higher than that of the control group. 6) Vitamin E levels in liver of all experimental diet groups were higher than that of control group and especially none added diet group and vitamin E added diet group were significantly higher than that of the control group. 7) Lipid peroxide in serum of all experimental diet group were lower than that of control group and especially EDTA added diet group. 8) Lipid peroxide in liver and spleen of all experimental diet groups were higher than that of the control group and lipid peroxide in kidney of all experimental diet groups except EDTA added diet group were higher than that of the control group. Four these results, as vitamin C, vitamin E and EDTA added diets have an effect to lipid peroxide by antioxidants, it could be suggested that perilla oil diet has required to add antioxidant because it has not sufficient vitamin E for antioxidant and intake and overtake level of perilla oil diet should be studied to go ahead.

Total saponin, protopanaxadiol-saponin and protopanaxatriol-saponin were isolated and purified from the side roots of red ginseng. After we administered them orally into rats during 5 weeks, we observed their effects on lipid and glucose content in rat serum. The change in body weight of protopanaxatriol- saponin treated group was slightly larger than those of other groups. Total lipid content in total saponin treated group showed an increase of about 20 % over that in control group. However, protopanaxadiol-saponin and protopanaxatriol- saponin treated groups showed no change. While triglyceride content in total saponin treated group decreased 29oyo compared to it s content in control group, its content in protopanaxatriol-saponin treated group increased 45%. Three saponin treated groups showed lower value than control group in total ant free cholesterol levels. While glucose content in total saponin treated group decreased slightly, that in Protopanaxadiol-saponin treated group decreased slightly compared to that in control group. And protopanaxatriol- saponin trented group showed the significant decrease of 25%. From these results, it is supposed that total saponin accelerates the conversion of lipid into glucose and that protopanaxatriol- saponin accelerates the conversion of glucose into lipid.

The study was done to investigate the effects of the extracts from the different parts of Lythrum salicaria (LS) on liver protective activities in chronically alcohol-treated rats. SD male rats except normal animals were administrated with alcohol ($30m{\ell}$ of 30%~40% ethanol/kg/day) and the extracts (300 mg/kg/day) for 10 weeks. Chronic alcohol administration decreased body weight, high density lipoprotein (HDL)-cholesterol and the reduced form-glutathione (GSH), whereas increased the ethanol content, glutamic-oxaloacetic transaminase (GOT), total cholesterol, low density lipoprotein (LDL)- cholesterol, triglyceride in blood/serum and the ratio of the oxidized form of glutathione (GSSG) and total GSH (GSSG/total GSH) in liver tissue. Groups treated with the extracts of leaf, root and stem, showed decrease in GOT, total cholesterol and GSSG/total GSH and increase in hepatic aldehyde dehydrogenase (ALDH), total GSH and serum albumin. Administration with the root extract of LS decreased blood ethanol content compared with the other part extracts. But, serum triglyceride values in rats treated with root and stem extract were higher than that of the negative control animals. Flower extract-fed group showed decrease in body weight and serum triglyceride, but increase in the ratio of GOT and glutamic-pyruvic transaminase (GPT), and GSSG/total GSH. From the results, we conclude that the extracts of root and leaf among the plant parts of LS might be useful for the amelioration of the chronic alcohol-induced liver demage of rat.
