This study was conducted to investigate the supplementary effects of Suwon 464 developed by Rural Development Administration, which has over two times of dietary fiber content compared with normal rice (Ilpum), on lipid metabolism in diabetic mice. We supplied 5 kinds of experimental diets (com starch diet as a control (CO), Ilpum polished rice diet (IP), Ilpum brown rice diet (IB), polished rice diet (SP) and brown rice diet (SB) of Suwon 464) to diabetic mice for 8 weeks, after analyzing dietary fiber contents of 5 experimental diets. Diet intake, body weight, organ weights, and lipids levels of serum, liver and feces were measured. The dietary fiber contents in CO, IP, IB, SP, and SB diets were 1.0, 1.2, l.4, 1.4, and 2.0% respectively. Body weight and liver and epididymal fat pad weights were lower in SB group than the other groups though there was no significant difference in diet intake among experimental groups. The concentrations of serum triglyceride was lower in SP and SB groups than CO and IP groups. The levels of hepatic total lipid and total cholesterol were significantly lower in SP and SB groups than CO group, and the level of hepatic triglyceride was lower in IB, SP and SB groups than CO group. The levels of total lipid and triglyceride excreted in feces were higher in IB, SP and SB, and the level of total cholesterol in feces was higher in SP and SB groups than CO group. These results suggested that the high dietary fiber rice (Suwon 464) decrease the triglyceride or total cholesterol concentrations of serum and liver by increasing of fecal lipid excretion in diabetic mice.

The effects of Taheebo on the diabetic-piegnant rats and their fetus was investigated. It has been reported that diabetic condition of the pregnant rats can affect the process of liver formation and damage the respiratory function in the fetus. Therefore we investigated the effects of Taheebo on the prevention of liver damage and respiratory failure in the fetus and those results were compared with that of dexamethasone (DXM). In pregnant rats, streptozotocin(STZ, 45 mg/kg, 0.01 M citrate buffer) was injected into the pregnant rats on the third day of pregnancy. Methanol extracts of Taheebo(500 mg/kg p.o.) was administered once daily during pregnancy. DXM (10 $\mu\textrm{g}$/g i.p.) was injected into the pregnant rats in 16th and 18th days of pregnancy. Body weights were measured and fetal number and abortion rate in pregnancy rats were determined. Lecithin/sphingomyelin ratio in amniotic fluid and malondialdehyde, glycogen, triglyceride, protein and cholesterol levels in the liver homogenate were determined. Also blood glucose level was analyzed. Body weights of maternal rats were increased in the all groups except the DXM group. Fetal number of the Taheebo treated group was similar to the control group, and a significant increase in the body weights of fetus was observed in the STZ treated group and the Taheebo treated group compared with the control group. Blood glucose of fetus produced hypoglycemia in the control group and hyperglycemia in the diabetic-pregnant rats. The protein and cholesterol levels in fetus liver were significantly increased in the DXM treated group compared with the control group. Triglyceride content was significantly increased in all groups compared with the control group. Liver malondialdehyde level of fetus in the STZ treated group was similar to the control group. Glycogen level was significantly increased in the all groups compared with the control group. Methanol extract of Taheebo showed hypoglycemic effect on the pregnant rats. However, we could not observe any hypoglycemic effect on the fetus. There's no difference between the control and Taheebo treated group in terms of the levels of triglyceride, cholesterol, protein and glycogen in the fetus liver. Further study to identify the effect of Taheebo on the fetus is under investigation.

A cross-sectional study to determine dietary intake and plasma triglyceride total cholesterol LDL-cholesterol and HDL-cholesterol of 185K Korean men was conducted across three different age groups The younger group (age 21 to 34) was significantly (p<0.001) taller but showed lower (p<0.05) percent body fat than the older group (age 45 to 60) Weight and body mass index was not different among age groups. Older men showed significantly(p<0.01) lower energy and total fat intake than younger men Besides macronutrients, most participants consumed an adequate amount of micronutrients but calcium consumption of the middle age group (age 35 to 44) was less than 75% of RDA In older men plasma triglyceride(207.8$\pm$155.5 mg/dl) total cholesterol (201.4$\pm$40.0 mg/dl) and LDL-cholesterol(106.0$\pm$32.7 mg/dl) concentrations were significantly hight(p<0.001) than in younger men wereas no significant difference was observed in HDL-cholesterol concentration Subjects with a higher BMI(bMI$\geq$25.0) showed significantly higher (p<0.001) triglyceride(200.2$\pm$107.6 mg/dl) total cholesterol(211.0$\pm$40.1 mg/dl) LDC-cholesterol(118.16$\pm$35.5 mg/dl) concentrations and lower(p=0.001) HCL-cholesterol concentration (52.8$\pm$15.9 mg/dl) than subjects with lower BMI(BMI<23.0) Dietary intake of fat cholesterol did not show significant associations with any of the plasma lipid profiles. However, anima fat intake was significantly (p<0.05) correlated with plasma total cholesterol and triglyceride concentrations in the older age group. On the hand percent body fat was correlated (p<0.05) with all of the plasma lipid and lipoprotin concentrations examined for all age groups Results indicate both dietary intake and percent body fat are important determinants of the plasma lipid concentrations is the elderly but only percent body fat or body mass could be valid predictors for the plasma lipid concentrations of the younger age group.

The results which were examined changes In contents of constitutive lipid and fatty acid during the natural drying of Pacific Saury were as follows. During the natural drying of Pacific Saury, offal lipid and moisture contents gradually decreased. In the survey of rancidity degree extracted lipid of Pacific Saury, peroxide value was gradually Increased, TBA and acid value were radically increased thereafter 9 days of drying. Neutral lipid, phospholipid and glycolipid contents of total lipid were 95%, 4% and 2%, respectively, and in the neutral lipid, content of TG was more than 90%, and in the phospholipid, contents of PC and PE were 45∼85%, 27∼34%, respectively. Fatty acid composition of total lipid was substantially higher in C18:0 and C20:1, C22:1, C22:6 contents and fatty acid composition of neutral lipid was higher In C22:1, C22:1, contents and fatty acid composition of phospholipid was the highest in C22:6 content. In the fatty acid composition of glycolipid, monounsaturated fatty acid content has substantially higher, C16:0 content was gradually Increased In saturated fatty acid and C22:1 content was gradually decreased in monounsaturated fatty acid. It showed that fatty acid composition of triglyceride has higher in monounsaturated fatty acid content and contents of C20:1, C22:1 was gradually decreased.

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.

This study investigated the effect of the powder of the small water dropwort(PSWD) and brewer's yeast(BY) on the liver function and serum lipid metabolism in alcohol-consuming rats. Male Sprague-Dawley rats were fed an AIN-93 diet(control), ethanol plus control(A), ethanol plus PSWD(AS), ethanol plus BY(AB), ethanol plus PSWD and BY(ABS) diet for seven weeks. The feed intake, body weight gain and feed efficiency ratio were the lowest and in the alcohol-consuming groups. The weight of the liver, kidney, spleen and epididymis of the anatomized rats showed positive correlation with the body weight gain. Compared with group A, the content of the lipid in the serum was significantly low in the AS and AB groups. In particular, it was the most effective in the AB group. The GOT, GPT and ALP level in the serum showed a significant difference in the alcohol-consuming groups. Compared with the A group, they showed a significantly low difference in the AS and AB groups. The total cholesterol and triglyceride levels in the liver were similar in all groups. The weight of the feces was significantly different but there was no significant difference in the content of total cholesterol and triglyceride levels in the AS and AB groups. These results suggest that BY and PSWD improve the liver function, and had an effect on reducing the lipid content of the serum and feces of alcohol-consumed rats. In particular, the effect of BY which contained protein, dietary fiber and vitamin B was higher than that of PSWD.

흰쥐에게 동충하초 추출분말 처리 사료를 식이한 결과 중성지질, 총 콜레스테롤 및 인지질 함량의 감소효과는 중성지질에서 가장 뛰어난 효과를 보인 반면 총 콜레스테롤 및 인지질 함량 감소에는 상대적으로 그 효과가 낮은 것으로 판명되었다. 이 때, 이들 지질성분의 함량 감소에 미치는 동충하초 추출분말의 처리효과는 3%(w/w)가 적정수준 이었다. 혈장 포도당 농도는 동충하초 추출분말 처리량이 증가할수록 감소하는 반비례의 관계를 나타내었으나 처리량의 증가에 따른 비례적 감소는 아닌 것으로 밝혀졌다. 혈장, 췌장, 근육조직의 인슐린 분비량의 변화는 혈장 포도당 농도변화와 거의 유사한 경향을 보였는데, 동충하초 추출분말의 처리량과 인슐린 분비량 사이에는 처리량의 증가에 따라 지속적으로 인슐린 분비량이 감소하는 정의 상관관계가 도출 되었다.
