Comparative blood analysis was carried out to investigate the change of blood constituent in TAE-EUM-IN group and control group. RBC, WBC, hemoglobin, hematocrit, total protein, triglyceride, phospholipid, total cholesterol, LDL-cholesterol, HDL-cholesterol, BUN, creatinine, ACTH, cortisol and prostaglandin E and $F_2{\alpha}$ were measured. And the following results were obtained: 1. In the change of blood cell, the value of hematocrit showed significant difference, while that of RBC, WBC and himoglobin didn't. 2. In the change of protein, the value of total protein showed significant difference, but that of albumin didn't. 3. In the change of lipid and cholesterol in serum, the value of triglyceride, phospholipid, total cholesterol and LDL-cholesterol indicated significant difference, while that of HDL-cholesterol indicated significant difference, while that of HDL-cholesterol didn't. 4. The value of BUN in serum represented significant difference, but that of creatinine didn't. 5. The value of cortisol in plasma showed significant difference, but that of ACTH didn't. 6. The value of prostaglandin E and $F_2{\alpha}$ in plasma showed significant difference. These results suggest that investigation on hormones and blood constituents enables objectification in differentiation of four types of physical constitution.
This study was performed to observe how soy protein and calcium in rats fed unsaturated fat-enriched diet affect the total lipid and cholesterol contents of blood and tissues male Sprague-Dawley rats weighing approximately 220g were fed four purified diets which contained 18% (w/w) corn oil, 1% (w/w) cholesterol, two sources of protein : casein or isolated soy protein (ISP) and two levels of dietary calcium : 0.1% or 1.0%, first for four weeks (Expt. 1) and second for eight weeks (Expt. 2). The contents of total lipid, cholesterol and triglyceride in blood, liver, heart and feces were determined. After four weeks feeding, the serum lipid and cholesterol concentration was not significantly different among the groups. After eight weeks feeding, these concentrations were significantly lower in ISP-High calcium group. The serum lipid concentration was influenced by dietary protein sources and calcium levels. These results indicated that the hypolipidemic effects of soy protein and high calcium intake were partly due to decrease in lipid absorption and these effects were not detected at 4 weeks feeding but 8 weeks feeding.

A differential specific pattern of variation in the metabolism of protein and cholesterol was noticed in non -diapause and diapause eggs due to the significant differences in embryonic development. The rate of metabolism was different due to specific demands of such metabolites during active embryogenesis and maintenance of diapause respectively. In general, the metabolic rate was found to be accelerated in non- diapause eggs just after egg deposition, while it was very slow in diapause eggs. When the diapause eggs were treated with hydrochloric acid within 16-20 hrs, the rate of turnover was found to very similar to non- diapause eggs, though the base level of protein and cholesterol was recorded to be different.
Hypocholesterolemic effect of soy protein was examined in comparison with casein and three other dietary protein sources in chicks. In two feeding trials, 40 (Expt.1) or 50 (Expt. 2), three-day-old, male chicks were forced-fed each of five semi-purified-type diets containing isolated soy protein (ISP, cp 82%), casein (cp 92%), rice protein (RP, cp 70%), corn gluten meal (CGM, cp 65%) or fish meal (FM, cp 70%) for two weeks. The diets for Expt. 2 were supplemented with 0.3% cholesterol by replacing glucose. Each protein source was the only source of protein of each diet. Essential amino acids were added to the diets to satisfy their requirements according to NRC. The diets were forced-fed to equalize the intake of all nutrients except the amino acids which were inherently variable in the diets. Chicks fed casein showed lower body weight gain than those fed the other proteins in both experiments. Birds fed ISP and FM gained better body weight than the others. Chicks fed casein showed significantly higher levels of plasma total cholesterol, non-HDL cholesterol and triacylglycerol (TG) than those fed ISP and the other protein sources. Meanwhile, the chicks fed ISP, RP, CGM and FM showed comparable levels of plasma total cholesterol, non-HDL cholesterol and TG. In Expt. 2, the birds fed casein and FM showed markedly elevated plasma total cholesterol and non-HDL cholesterol levels. Liver weight and levels of total lipids and cholesterol of chicks fed casein appeared significantly higher than those of the other protein diets, whereas those of the chicks fed ISP, RP, CGM and FM appeared comparable except cholesterol in FM group. In conclusion, only the chicks fed casein diets in both experiments always showed significantly higher levels of plasma cholesterol and TG compared to those fed ISP and the other protein sources. These results support the views that casein, which has unique lysine-arginine ratio, is inherently hyper-cholesterolemic, and ISP is hypocholesterolemic only when compared to casein.

This study investigated that the antioxidative effect of freeze-dried cranberry powder against protein and lipid oxidation and ameliorative effect of serum lipid profile in rat fed atherogenic diet. Six weeks old male Sprague-Dawley rats were divided into the following four groups: normal diet group with 5% com oil(control), atherogenic diet group with 5% com oil, 10% lard, 1% cholesterol, and 0.5% sodium cholate(HFC), atherogenic plus 2% cranberry powder diet group(HFC+C2), and atherogenic plus 5% cranberry powder diet group(HFC+C5), and respective diet and water were fed daily for 6 weeks. After the experimental period, the serum lipid profile, such as total cholesterol, HDL-cholesterol, LDL-cholesterol, and triglyceride, ferric reducing ability of plasma(FRAP), plasma phenolics content, superoxide dismutase(SOD) activity, serum protein carbonyl and thiobarbituric acid reactive substances(TBARS) levels were examined. Total phenolic compound and total flavonoid levels in freeze-dried cranberry powder were 9.94 mg/g and 8.12 mg/g, respectively. Serum total cholesterol and LDL-cholesterol levels were not significantly different for cranberry powder treatment, but serum HDL-cholesterol level was significantly increased in HFC+C5 group compared with HFC group. Plasma FRAP value tended to be increased by cranberry powder treatment though there was no significant difference. Plasma total phenol concentrations and SOD activities were not significantly different among all groups. Serum protein carbonyl and TBARS levels were significantly decreased in HFC+C5 group compared with HFC group. Overall results suggested that freeze-dried cranberry powder might have the serum lipid improving effect, as well as anti oxidative effect demonstrated by its protective effect against protein and lipid oxidation.
Cardiovascular diseases (CVDs) are the most common cause of death in patients with nonalcoholic fatty liver disease (NAFLD) and dyslipidemia is considered at least partially responsible for the increased CVD risk in NAFLD patients. The aim of the present study is to understand how hepatic de novo lipogenesis influences hepatic cholesterol content as well as its effects on the plasma lipid levels. Hepatic lipogenesis was induced in mice by feeding a fat-free/high-sucrose (FF/HS) diet and the metabolic pathways associated with cholesterol were then analyzed. Both liver triglyceride and cholesterol contents were significantly increased in mice fed an FF/HS diet. Activation of fatty acid synthesis driven by the activation of sterol regulatory element binding protein (SREBP)-1c resulted in the increased liver triglycerides. The augmented cholesterol content in the liver could not be explained by an increased cholesterol synthesis, which was decreased by the FF/HS diet. HMG-CoA reductase protein level was decreased in mice fed an FF/HS diet. We found that the liver retained more cholesterol through a reduced excretion of bile acids, a reduced fecal cholesterol excretion, and an increased cholesterol uptake from plasma lipoproteins. Very low-density lipoproteintriglyceride and -cholesterol secretion were increased in mice fed an FF/HS diet, which led to hypertriglyceridemia and hypercholesterolemia in Ldlr-/- mice, a model that exhibits a more human like lipoprotein profile. These findings suggest that dietary cholesterol intake and cholesterol synthesis rates cannot only explain the hypercholesterolemia associated with NAFLD, and that the control of fatty acid synthesis should be considered for the management of dyslipidemia.
In order to observe the effects of resistant starches on the physio-nutrition in women, nine female university students were investigated using cellulose (CED), resistant starch 3 (RS3D) and resistant starch 4 (RS4D) diets. Each woman's daily intake and excretions of energy, protein and lipid were mesured together with the apparent digestibility and the amounts of total cholesterol and HDL-cholesterol were measured. The results obtained from this researh are as follows. The daily energy intake were significantly higher in the RS4D (Resistant starch 4 diet) compared with the CED(Cellulose) and the RS3D (Resistant starch 3 diet). The metabolic energy in those periods with RS added to their diets were significantly higher whereas the metabolic energy in the period CED was significantly low. The daily protein intake was significantly higher in the RS4D compared with the CED and the RS3D. The apparent digestibility of protein was significantly higher in the RS4D compared with the CED and the RS3D. The daily lipid intake was significantly higher in the CED compared with the RS3D and the RS4D. The apparent digestibility of lipid was not significant in that period. The concentration of total cholesterol, HDL-cholesterol, % of HDL-cholesterol and atherogenic index (A.I.) were not significant in those period. As the above results indicate, while RS3 appear to have similar effect on energy consumption rate, apparent protein digestibility and content of cholesterol in plasma, compared with the CED, but energy consumption rate and apparent digestibility of protein are significantly higher in the RS4D compared with the CED. Thus, it appears that cellulose and RS 3 share similar effects on physio-nutrition in human, while RS4 does not have the similar effects. (Korean J Nutrition 35(9) : 932∼942, 2002)
In this paper it was attempted to observe the effect of defatted panax ginseng supplement of the growth rate, feed and protein efficiency ratios, and the contents of cholesterol, total lipid and protein in the serum, liver and aorta in Sprague-Dowley Albino male rat (weighing 83 ${\pm}$ 4 g). Seven kinds of experimental diets were prepared as follows : Stock (control) diet, ginseng control diets supplemented with 0.5, 1.0 and 3.0% of ginseng powder to the stock diet, and defatted ginseng Powder diets supplemented with 0.5, 1.0 and 3.0% of defatted ginseng powder to the stock diet. .All diets contained same level of lipid and protein, respectively. The results obtained are as follows : 1. The growth rate in the feeding group of 0.5% defatted ginseng powder diet for 16week were higher than other diet groups. 2. Feed and Protein efficiency in 0.5% defatted ginseng group showed similar tendency to that in body growth rate. 3. The total cholesterol contents in the serum of 0.5% defatted ginseng Powder diet$.$ group showed the tendency to decrease gradually for 4 to 12 weeks, maintaining higher level than other groups. The free cholesterol contents in the serum of defatted ginseng powder diet group in 8 the and 16th weeks were higher than all ginseng control diet group. The total and free cholesterol contents in the liver of all defatted ginseng diet groups in 16th week were higher than hose of all ginseng control groups. The total cholesterol content at 12h week and the free cholesterol content at 16th week i n the aorta of all defatted ginseng diet groups were lower than those of ginseng control groups, respectively. 4. The total lipid contents in the serum of 1.0 and 3.0% defatted ginseng diet groups at 2nd to I2th weeks were lower than other groups, and those in the liver and aorta of all defatted ginseng diet groups at 12th weeks were lower than those of ginseng control diet groups. 5. The protein contents of the serum and aorta were continuously increased throughout whole experimental period in all experimental groups. The protein content of the liver of all groups were decreased at 2nd week and after then no change was observed.

This study was performed to investigate the effects of silk protein enzyme hydrolysates on blood glucose and serum lipid in db/db diabetic mice. Twelve week-old-male C57BL/KsJ db/db mice were divided into two groups: diabetic control group and 0.25% silk protein hydrolysates solution group, which were fed for 8 weeks. Body weight increased in the silk protein hydrolysates group compared with the diabetic control group. There were no differences in food and water intake between the diabetic control and the silk protein hydrolysates groups. The weight of liver increased in the silk protein hydrolysates group while that of kidney increased in the diabetic control group. The blood glucose level increased about 18.0% in the diabetic control group after 8 weeks while that in the silk protein hydrolysates group increased about 5.8%. Also, silk protein hydrolysates improved the glucose tolerance in C57BL/KsJ db/db mice. There was no difference in total cholesterol and non-HDL cholesterol concentration between the diabetic control and the silk protein hydrolysates group. Triglyceride concentration were lower in the silk protein hydrolysates group than in the diabetic control group (p<0.05) while HDL-cholesterol concentration were higher in the silk protein hydrolysates group than in the diabetic control group (p<0.05). This results suggest that administration of silk protein enzyme hydrolysates reduces significantly an increasing rate of 1]food glucose, decreases triglyceride, and increases HDL-cholesterol in C57BL/KsJ db/db mice.
