Plasma cholesterol is increased in normal aging in both rodents and humans. This is associated with reduced elimination of cholesterol and decreased receptor-mediated clearance of plasma low-density lipoprotein (LDL) cholesterol. The aims of this study were: (1) to determine age-related changes in plasma lipid profiles, and (2) to determine the effect of fenofibrate, an activator of peroxisome proliferator activated receptor alpha (PPAR $\alpha$), on plasma lipid profiles in normal rats on a standard diet. Male Sprague-Dawley (SD) rats (n=15) were fed standard chow and water from 10 to 25 weeks of age. During that period, we measured daily food intake, body weight, fasting and random blood glucose levels, plasma total cholesterol (TC), triglycerides (TG), and free fatty acid (FFA) levels. At 20 weeks of age, all rats were randomly divided into two groups: a fenofibrate group (in which rats were gavaged with 300 mg/kg/day of fenofibrate) and a control group (gavaged with water). Fenofibrate treatment lasted 5 weeks. There were no significant changes in daily food intake, blood glucose, and plasma TG level with age. Body weight, plasma TC, and FFA levels were significantly increased with age. Fenofibrate significantly decreased plasma concentrations of TC and FFA, which had been increased with age. However, fenofibrate did not influence the plasma concentration of TG, which had not increased with age. These results suggest that fenofibrate might have a novel role in preventing age-related hypercholesterolemia in SD rats on a normal diet.

This study was carried out to investigate the effects of activated carbon (AC) on growth, ruminal charateristics, blood profiles and feed digestibility in sheep, using roughage-based or concentrate-based diets. Twelve Suffolk breed of sheep of similar age and weight were distributed into 4 groups in a $2{\times}2$ factorial design. Two groups were fed a roughage-based diet with (R + AC) and without AC (R - AC), while the other two were fed a concentrate-based diet with (C + AC) and without AC (C - AC), respectively. The addition of 0.3% AC was based on dry matter of feed offered to animals. The incorporation of AC in roughage and concentrate based diets had no marked effects on feed intake, daily gain and feed conversion of the animals within experimental diets. The results obtained might be due to the low level of AC added in the diet. The animal on both concentrate-based diets were higher than the roughage-based diets in terms of daily gain and feed conversion ratio. However, it was observed that the animals provided with AC in the concentrate-based diet did not suffer from diarrhea and easily adjusted to high concentrate feeding. Further, the pH value for all diets before feeding was noted to be similar. After feeding, however, pH was shown to be higher in R + AC (p < 0.05) than in C + AC diet. Rumen protozoa number was decreased after feeding for both + AC diets, but in C - AC diet it was higher than in the roughage-based diets. For ammonia-nitrogen, C - AC was found to be higher than C + AC diet and the roughage-based diets before feeding. Total volatile fatty acid concentration, propionate and valerate molar ratios for both diets and time of collection were not affected. However, acetate, butyrate and valerate molar ratios were observed to be affected by diets and time of collections. The diets with AC increased (p < 0.05) before feeding for acetate molar ratio, but not different within diet, however, the roughage diets were found to be higher (p < 0.05) in acetate than the concentrate diet. In the blood parameters, the glutamic pyruvic transaminase (GPT), red and white blood cell (RBC, WBC) counts and packed cell volume (PCV) did not differ within and among the diets. Likewise, the WBC differential count in both diets with either - AC or + AC were similar in trend. However, lymphocyte count was noted to be increased in R + AC than the R - AC diet. The addition of AC in both diets did not affect nutrient digestibilities within diets.

Backgrounds Diabetes mellitus is associated with accelerated atherosc lerosis and predispose to specific microvascular problems. This study was performed to evaluate the usefulness of red ginseng as adjunctive therapeutic agent of NIDDM especially in preventing chronic diabetic complications. Materials and Methods We treated 50 patients with NIDDM for 5 month with 2 regimens: 1)oralhypoglycemic drug therapy only(the control group), 2)oral hypoglycemic group). The patients were recruited at Korea university hospital from June, 1992 to October, 1992 and the following inclusion criteria were used: l)age above 35 years 2)initial body weight within or above ideal body weight 3)fasting blood glucose level greater than 140mg/dl 4)no previous history of diabetes mellitus or no history of blood glucose control for recent 3 months of more. The patients were seen every 2 weeks for remaining 3 months. At every visit FBS and PP2hr blood glucose were measured with blood pressure and body weight. Lipid profiles were checked every 4 weeks and platelet function test was perfomed with aggregometer after administration of ADP, epineprine and collagen every 4 weeks. Free fatty acid were also analyzed every 8 weeks and glycosylated hemoglobin was measured every 12 weeks. Results The results were as follows: 1. The mean values for fasting and PP2hr blood glucose decreased significantly in the control group than in the ginseng group. 2. The weight gain was less in the ginseng group than in the control group. The levels of systolic blood pressure decreased' significantly in the ginseng group than in the control group. 3. There was no significant differences of lipid profiles in both groups. 4. The platelet hyperaggregation was improved more significantly in the ginseng group than in the control group. Conclusions In patients with NIDDM who were recieving oral hypoglycemic drug therapy, the addition of red ginseng improved platelet function and blood pressure, but induced less weight gain. The data suggests that red ginseng may be useful as a therapeutic adjunct especially in preventing chronic complications of NIDDM.

The aim of this study was to investigate the effects of Korean rice wine residue (RWR) on the growth performance and blood profiles of Hanwoo steers in the fattening stage. In situ and in vivo experiments were conducted to analyze rumen fermentation characteristics and total tract digestibility, respectively. Three cannulated Hanwoo steers (mean body weight: 448 ± 30 kg) were used in both analyses. The growth performance of 27 experimental animals in the fattening stage (initial body weight: 353.58 ± 9.76 kg) was evaluated after 13 months of feeding. The animals were divided into three treatment groups (n = 9/group). The treatments comprised total mixed ration (TMR) only (CON), TMR + 10% RWR (10% RWR), and TMR + 15% RWR (15% RWR). The diets of equal proportions were fed daily at 08:00 and 18:00 h based on 2% of the body weight. The animals had free access to water and trace mineral salts throughout the experiment. Supplementation of 15% RWR significantly decreased (p < 0.05) the rumen fluid pH compared with the control treatment, but there was no significant difference in the total volatile fatty acid concentration. It also significantly increased (p < 0.05) dry matter digestibility compared with the other treatments. The total weight gain and average daily gain of the animals in the RWR-supplemented groups were significantly higher (p < 0.05) than those in the control group. Furthermore, the feed intake and feed efficiency of the RWR-supplemented groups were higher than those of the control group. Supplementation of RWR did not affect the alcohol, albumin, glucose, total cholesterol, triglyceride, and low-density lipoprotein concentrations, and aspartate aminotransferase and alanine transaminase activities in the blood; these parameters were within the normal range. The high-density lipoprotein and creatinine concentrations were significantly higher in the 15% RWR group, whereas the blood urea nitrogen concentration was significantly higher in the 10% RWR group than in the other groups. These results suggest that TMR with 15% RWR can serve as an alternate feed resource for ruminants.

콩은 양질의 단백질과 지방산이 풍부하며, 세계적으로 가장 많이 사용되는 형질전환작물(GM) 중 하나이다. 국내에서 GM콩은 주로 광안을 모본으로 하여 개발되고 있는 상황이다. 본 연구에서는 비표적 LC-MS 기반 대사체 분석기술을 이용하여 2020년도에 군위와 전주에서 재배한 광안과 세 일반콩의 대사체 프로파일을 비교분석 하였다. Partial least square-discriminant analysis (PLS-DA) 분석을 통하여 대사체 프로파일들은 품종별로 잘 분리되었으며, 페닐알라닌과 이소플라본, 지방산을 포함하여 18종 물질이 관여하는 것으로 확인하였다. PLS-DA 스코어 플롯에서 콩 4품종은 지역별로 클러스터를 형성하였으며, 이는 재배환경이 대사물질의 변화에 영향을 준 것으로 판단된다. 광안은 다른 품종들에 비하여 이소플라본 함량이 가장 낮았으며, 리놀렌산 함량은 가장 높았다. 광안을 이용하여 개발된 생명공학콩의 실질적동등성 평가의 경우 광안의 대사체 프로파일 특성을 고려한 비교품종 선정 등에 관하여 고찰하였다.

In this study, the effect of probiotic supplementation on growth performance, blood metabolites, and meat quality of Hanwoo steer was investigated. A total of 32 Hanwoo steers (15-17 months, average body weight $462{\pm}37.9kg$) were randomly allotted to 4 dietary treatments (0, 0.5, 1.0, and 1.5% mixed probiotics), with four Hanwoo steers per pen (two replicates per treatments), and reared for 12 months. There were no differences among treatments in growth performance of Hanwoo steer (P>0.05); however, feed intake decreased linearly with increasing levels of mixed probiotics. Growth hormone and Blood Urea Nitrogen (BUN) levels responded linearly with increasing levels of dietary mixed probiotics (P<0.05), but not insulin and blood glucose did not. In particular, total cholesterol was significantly lower for the 1% mixed probiotic treatment in comparison with that of the other treatments (P<0.05). The pH, Thiobarbituric Acid Reactive Substances (TBARS), cooking loss, and meat color were influenced by increasing levels of mixed probiotics (P<0.05), but the carcass characteristics and shear force were not. Regarding sensory evaluation, the addition of mixed probiotics resulted in significant difference in meat color, tenderness, aroma, off-flavor, juiciness, and marbling score, but not in overall acceptability. In addition, fatty acid profiles indicated no differences between control and mixed probiotic treatments. In conclusion, mixed probiotic treatment at 1% levels can enhance consumer preferences possibly by reducing cholesterol and TBARS.
