The protective effect of Carthamus tinctorius L. Semen on the carbon tetrachloride induced liver damaged rats were studied. First, methanol extract was prepared and the extract was fractionated with hexane, $CHCl_3$, BuOH and $H_2O$ respectively. Animals were divided into 6 groups and each group was treated with each fraction respectively. To investigate the hepato-protective effect of Carthamus tinctorius L. Semen AST, ALT, albumin, TP, cholesterol, TG, creatinine and total bilirubin values were measured in each treated group and compared with those of control group. GST activity was increased in BuOH group compared with the control group. In malondialdehyde levels, all fractions was decreased compared with the control group. In histopathologic examination, hexane and $H_2O$ fractions of Carthamus tinctorius L. Semen observed mild degree of ballooning degeneration. The results show the protective effect of Hexane,$CHCl_3$, BuOH and $H_2O$ fractions on hepatotoxicity of $CHl_4$ by decreasing ALT, AST, bilirubin, cholesterol, TG and BUN. It seems that the decrease of MDA are related to the recovery effect. The protective effects of Carthamus tinctorius L. Semen fractions in hepatotoxic pathogenesis by $CHl_4$ was suggested in blood chemistry analysis and histopathologic examination.

PURPOSE: The purpose of present study was to investigate effects of obesity, blood pressure and life style on lipid indices and blood pressure in men of age 40s. METHODS: One hundred forty five subjects in men of age 40s were participated in this study. All participants were taken physical examination, lifestyle survey and laboratory test. According to examination, participants were divided into two group in four categories ; obesity and normal group, hypertension and normal group, smokers and non-smokers, and drinkers and non-drinkers. The low density lipoprotein cholesterol (LDL), high density lipoprotein cholesterol (HDL), total cholesterol (TC), triglyceride (TG), systolic blood pressure (SBP), diastolic blood pressure (DBP) were analyzed by independent t-test for comparison between two groups. RESULTS: The values of LDL, TC, SBP, DBP were higher and HDL was lower in obesity than in normal group (p<.05). The values of LDL, TC, SBP, DBP were higher in hypertension group than in normal group (p<.05). The values of TG was higher and HDL was lower in smokers than in non-smokers (p<.05). There's no significant differences between drinkers and non-drinkers (p>.05). CONCLUSION: It can be seen that obesity and blood pressure were more relative risk factors than smoking and alcohol indices in cardiovascular diseases.

This study was designed to find out the effects of aerobic exercise on the serum lipids in the middle-aged women. The effects of aerobic dancing on serum total cholesterol(TC), triglyceride(TG) and HDL-cholesterol (HDL-C) were studied in eight sedentary women(control group) and twenty seven aerobic exercising women(aerobic group) , aged 35∼45%. Aerobic exercising subjects were divided into 3 group; 2 to 3 months exercising group(Al), 4 to 10 months exercising group(AH), over 1 year exercising group(AIII) according to the periods of exercise. The serum lipid levels of aerobic exercising groups(AI, AII, AIIII) were compared with those of control group. The results statistically analyzed were summarized as follows : 1) The serum TG levels of aerobic groups decreased very significantly compared with those of control group(p< 0.001) and tended to be lower with the increase in aerobic periods. But there were no significant differences among aerobic groups by ANOVA. 2) The serum TC levels of aerobic groups decreased compared with those of control group and tended to be lower with the increase of aerobic periods. But there were no significant differences among groups. 3) Serum HDL-cholestrol level of A I group was elevated significantly compared with that of control group and significant difference was observed according to the aerobic periods : AR group exhibited higher serum HDL-cholesterol values than AH group, and AH group higher than A I group.

In order to evaluate the mode of action of ginseng saponin. metabolic changes in the plasma of normal and aloxan-intoxicated rats were compared Normal groups were administered only ginseng saponin 0, 5, 50mg/kg for 16 days, but alloxan-intoxicated groups were administered alloxan 25mg/kg for 3 days in addition to ginseng saponin. (1) No significant change in the concentration of glucose, cholesterol, and triglyceride (TG) was observed in normal rats but great inhibitory effect, except elevation of TG, was observed in alloxan-intoxicated rats. However, blood urea nitrogen was elevated in both normal and alloxan- intoxicated rats by administration of ginseng saponin 50mg/kg, and it was considered to be due to the impaired kidney function caused by overdose toxicity. (2) In normal rats, COT and ALP actIn,its were not changed by administration of ginseng saponin but GPT activity was decreased significantly. In alloxan-intoxicated rats, ginseng saponin exerted inhibitory action on the elevation of COT, CPT and ALP activity. But administration of ginseng saponin Smghg was much more effective than administration of 50mg/kg. (3) There fore, we concluded that ginseng saponin has the adaptogenic activity showing little effect on normal metabolism but great preventive action on alloxan-intoxicated rats.

The objective of this study was to investigate the biological activities of fermented mugworts and their effects on the lipid metabolism in hyperlipidemia-induced rats. The proximate compositions of two kinds of mugwort, Artemisia capillaris Thumberg and Artemisiae asiaticae Nakai, were compared before and after fermentation. In both types of mugwort crude protein and amino nitrogen contents markedly increased with fermentation. Thrombolytic activity determined from the size of the clear zone on a fibrin plate was higher for the Artemisiae asiaticae Nakai, especially in the fermented sample. Antioxidative activity according to DPPH(1,1-diphenyl-2-picrylhydrazyl) radical scavenging effects was higher for Artemisia capillaris Thumberg but no significant differences were found between the samples after fermentation. The body weights of hyperlipidemia-induced rats that were fed the mugworts for 4 weeks were lower than those of the control group. In all the mugwort-fed rats serum total cholesterol and LDL-cholesterol levels remarkably decreased. Furthermore the fermented mugworts were found to be more effective at decreasing triglyceride (TG) levels. It is also noteworthy that the highest HDL-cholesterol levels were observed in the rats treated with the fermented Artemisiae asiaticae Nakai. And fatty liver weights were higher in the rats fed Artemisia capillaris Thumberg. In conclusion the feeding of fermented Artemisiae asiaticae Nakai was effective for increasing thrombolytic activity and HDL-cholesterol levels as well as reducing TG levels in rats.

This study was performed to investigate the effect of family type on the nutrient intake and nutritional status in elderly women. Blood samples and anthropometric data of elderly women aged from 60 to 78 years were collected in 1996, who visited a health examination center in Seoul to screen their health status. They were divided into two groups by their family type, one was extended family(extended family elderly, n=37) and the other was independently living(independently living, n=29). Nutrients intake was measured by interview using a simplified questionaire. Albumin, cholesterol, triglyceride(TG), hemoglobin (Hb), hematocrit, Ca, Mg, and alkaline phosphatase activity of serum were analyzed. Intakes of energy, protein, carbohydrate, Fe, vitamin A, niacin, thiamin, riboflavin, and vitamin C were not different between the two groups. However, fat and Ca intakes were higher(p<0.05) in extended family elderly than indepen dently living elderly. There are no significant difference in hematocrit value and serum concentrations of Hb, TG, and Ca. Serum Mg and cholesterol levels tended to be higher in extended family elderly. However, serum albumin level was lower(p<0.05) in extended family elderly. These results show that the indepen dently living elderly women had intakes of daily energy, fat and Ca compared to the extended family elderly. Therefore, the nutritional education for the independently living elderly will be focused on the health risk resulted from less intakes of Ca and total energy.

The purpose of this study was designed to observe the effects of Zizyphus jujuba seed extract on the concentrations of the lipids and blood glucose in the S.D. rats fed the experimental diets for 4 weeks. Concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, triglyceride (TG), phospholipid (PL) and blood glucose in serum were significantly higher in the cholesterol administration groups (group 2 (cholesterol+water), group 3 (cholesterol+Zizyphus jujuba seed extract)) than those in the control group (group 1, basal diet+water). But the concentrations of total cholesterol, atherosclerotic index, LDL, LDL-cholesterol, free-cholesterol, cholesteryl ester, TG, PL and blood glucose in serum ware remarkably lower in the group 3 than those in the group 2. In the ratio of HIDL-cholesterol concentration to total cholesterol and HDL-cholesterol concentration, Zizyphus jujuba seed extract administration group was higher percentage than in the group 2. The activities of aspartate aminotransferase (AST), alanine amino-transferase (ALT), lactate dehydrogenase (LDH) and alkaline phosphatase (ALP) in serum were rather lower in the Zizyphus jujuba seed extract administration group (group 3) than in the cholesterol diet group (group 2). From the above research, Zizyphus jujuba seeds were effective on the improvement of the blood glucose, lipid compositions in serum of dietary hyperlipidemic rats. And particularly, Zizyphus jujuba seeds were more effective as a therapeutic regimen for the control of metabolic derangements in adult disease.

The main purpose of this study is to examine the effect of caffeine on lipid accumulation in human hepatoma HepG2 cells. Significant decreases in the accumulation of hepatic lipids, such as triglyceride (TG), and cholesterol were observed when HepG2 cells were treated with caffeine as indicated. Caffeine decreased the mRNA level of lipogenesis-associated genes (SREBP1c, SREBP2, FAS, SCD1, HMGR and LDLR). In contrast, mRNA level of CD36, which is responsible for lipid uptake and catabolism, was increased. Next, the effect of caffeine on AMP-activated protein kinase (AMPK) signaling pathway was examined. Phosphorylation of AMPK and acetyl-CoA carboxylase were evidently increased when the cells were treated with caffeine as indicated for 24 h. These effects were all reversed in the presence of compound C, an AMPK inhibitor. In summary, these data indicate that caffeine effectively depleted TG and cholesterol levels by inhibition of lipogenesis and stimulation of lipolysis through modulating AMPK-SREBP signaling pathways.

Since biodiesel as bioenergy is defined as ester compounds formed by esterification of animal/vegetable oils, in this study three vegetable cooking oils (market, waste and refined waste ones) were esterified by reactions of alkali catalyst and immobilized enzyme. The fatty acid composition of the formed ester compounds was analyzed to investigate the feasibility of biodiesel production. By lipolysis (i.e, hydrolysis of Triglyceride (TG)), all three vegetable oils used in this study were found to produce Diglyceride (DG), Monoglyceride (MD) and Fatty acid ethylester (FAEE). However, the amount of produced FAEE (which can be used as an energy source) was in the increasing order of market cooking oil, waste one and refined waste one. With NaOH catalyst, FAEE was produced about 24.92, 17.63 and 11.31 % for the respective oils while adding Lipozyme TL produced FAEE about 43.54, 38.16 and 24.47 %, respectively. This indicates that enzyme catalyst is more effective than alkali one for transesterification. In addition, it was found that the composition of fatty acids produced by hydrolysis of TG was unchanged with alkali and immobilized enzyme reactions. Thus it can be expected that stable conditions remain in the course of mixing with gasoline whose composition is similar to that of the fatty acids.

The aim of this study was to evaluate the effects of oligosaccharides(fructo or isomalto ) contained in sponge cake on blood lipids and intestinal physiology in rats. The experimental diet was mixed with 30% sponge cakes. Normal male Sprague Dawley rats weighing about 530g were randomly assigned to three groups and placed experimental diets and deionized water at free access for 25 days. Rat in control group received a diet mixed with sponge cake containing sucrose only at 21.58g/100g diet and rats in the other two groups received diets mixed with sponge cakes of which 40% sucrose was replaced with each oligosaccharide. The results obtained were as follows: No significant differences in efficiency of food, liver weight and intestinal length were observed among groups. The cecal contents and cecal wall weights were increased more in fructooligosaccharide(FO) group than control. The pH of cecal contents decreased significantly in two oligosaccharide groups. The water contents of fresh feces in FO group were the highest and the those of two oligosaccharide groups were higher than that of control. Dry fecal weight increased significantly in isomaltooligosaccharide(IMO) group. Total serum cholesterol concentration was significantly lower in FO group. Serum triglyceride(TG) was not significantly different among three groups at p<0.05, but serum TG of FO group was lower than those of other groups. In conclusion, 40% replacement of sucrose with oligosaccharides in sponge cake may have beneficial effects on lipid metabolism and intestinal function in rats.
