This study was carried out to examine how dietary protein and calcium levels in rats fed fat-enriched diet affect the total lipid and cholesterol contents of blood and tissues. Male Sprauge-Dawley rats weighing approximately 200g were fed six purified diets which contained 18%(w/w) beef tallow, 1% (w/w) cholesterol, two source of protein, casein or isolated soy protein (ISP) and three levels of dietary calcium, 0.1%, 0.4% and 1.0%, first, for four weeks, and second, for eight weeks. The contents of the total lipid, cholesterol and triglyceride in blood, liver, heart and feces were determined. After four weeks feeding serum lipid and cholesterol concentrations significantly decreased in rats fed 1.0% (w/w) level calcium, regardless of dietrary protein sources. After eight weeks, these concentrations were significantly lower in the rats fed soy protein than in casein-fed rats. As dietary calcium level increased serum and tissue lipid and cholesterol contents were decreased and fecal lipid excretion increased. It is concluded that hypolipidemic and/or hypocholesterolemic effects of soy protein and calcium were partly due to decrease in lipid absorption.

This study was undertaken to examine relations between obesity and birthweight, parental weight and serum biochemical levels(lipids , glucose, insulin and aminotransferase) in elementary school children aged 10-12 . The weight of obese girls was higher than that of obese boys, while WHR was higher in obese boys than in obese girls. The birth weight of the obese children was significantly higher than that of the non-obese children(p<0.01), and was positively correlated with current weight. The concentrations of serum TG, LDL, VLDL, LDL-cholesterol, glucose, insulin and ALT in obese children were much higher than those in non-obese children . However, the serum HDL -cholesterol concentration of the obese children was significantly lower compared with that of the no-obese children. On the other hand, little differences in these levels were found between genders. The concentrations of PL, TC and AST in the groups showed no significant differences. In the obese children, serum concentrations of TG, LDL-cholesterol , glucose and ALT were more closely associated with GMI than with WHR. No significant correlation was found with serum insulin , glucose and TG levels. These data show that childhood obesity may be related to hyperlipidemia , atherosclerosis, hypertension, diabetes mellitus and fatty liver.

This study was performed to investigate the effect of chitosan and NOCC from different sources and of different molecular weights on lipid metabolism. Sprague-Dawley rats were blocked into 26 groups according to body weight, and were raised for 4 weeks. Cadmium chloride was given at the level of 0 or 400 ppm in diet. Various chitosan and NOCC sources were given at the level of 0%(w/w) of diet. Total serum cholesterol and serum triglyceride concentrations were little affected by chitosan and NOCC supplements. However, HDL-cholesterol concentration and HDL : total cholesterol ratio were increased , and liver lipid, cholesterol , and triglyceride concentration were decreased by chitosan and NOCC supplements. The cholesterol and lipid lowering activity depends on fiber sources(crab and shrimp); type (chitosan and NOCC); and molecular weight(low , medium , and high). Among cadmium-free groups, chitosan-fed groups showed greater activity than NOCC -fed groups in lowering cholesterol and lipid levels, and greater fecal excretion of lipids and bile acids. Crab chitosans were more effective in cholesterol and lipid lowering activity than shrimp chitosans. The group fed high molecular weight crab chitosan showed the highest fecal excretion of lipids and bile acids. This indicated that high molecular weight crab chitosan was most effective in interfering with cholesterol and lipid absorption.

Purpose: The aim of this study is to evaluate the relationship between abdominal subcutaneous fat thickness measured by ultrasonography (US) and serum lipid profile and liver transaminases in obese children. Methods: One hundred and sixty-six children diagnosed with obesity from May 2001 to December 2013 were included in this study. Data on serum lipid profile and liver transaminases were collected from clinical records. Abdominal subcutaneous fat thickness and grade of hepatic steatosis were evaluated by US. Results: Of the 166 children, 107 were diagnosed with hepatic steatosis by US, 46 with grade I, 56 with grade II, and five children with grade III. According to the grade of hepatic steasosis, the average values of midline abdominal subcutaneous fat thickness and right flank abdominal subcutaneous fat thickness measured $2.9{\pm}0.8cm$ and $1.9{\pm}0.7cm$ in the normal group, $3.3{\pm}0.8cm$ and $2.0{\pm}0.7cm$ in grade I, $3.8{\pm}0.8cm$ and $2.3{\pm}0.8cm$ in grade II, and $4.1{\pm}0.8cm$ and $2.8{\pm}1.4cm$ in grade III, respectively. Abdominal subcutaneous fat thickness correlated with grade of hepatic steatosis (p<0.01). In addition, abdominal subcutaneous fat thickness correlated with concentration of serum lipids and liver transaminases in the age group of 12-14 years (p<0.01). Conclusion: Abdominal subcutaneous fat thickness measured by US can be used as a reliable predictor of possible hyperlipidemia and steatohepatitis in children, especially during the adolescent stage.

The purpose of the study was to find an effect of Medium Chain Triglycerids (MCT) diet on cholesterol metabolism in rat. Sprague-Dawley rats were fed two different diets containing MCT(trioctanoate) and corn oil respectively. After feeding to each group for four weeks, the levels of serum and liver cholesterol, the excretion rates of fecal and biliary steroids, and also bile acid composition were investigated. The results obtained from the study are as follows : (1) The average body weight gain in MCT group was almost same as that in the corn oil group. (2) The concentration of serum cholesterol in MCT group was lower than that in the corn oil group. Therefore it is confirmed that the cholesterol lowing action of MCT diet was practically high. (3) The concentrations of liver cholesterol and Triglyceride in MCT group were almost same as that in the corn oil group. Therefore it is thought that the level of liver lipids was not influenced by the difference of diet in this study. (4) The excretion rate of fecal neutral steroid in MCT group was significantly lower than that in the corn oil group, while the rate of fecal bile acid excretion was about same in both MCT and corn oil group. (5) The composition rates of fecal bile acid such as cholic acid, chenodeoxycholic acid and deoxycholic acid, a secondary acid of cholic acid, in MCT group were significantly lower than that in the corn oil group. (6) The excretion rates of biliary cholesterol and bile acid in MCT group were significantly higher than that in the corn oil group, while the composition rates of biliary bile acid such as chenoddeoxycholic acid and deoxycholic acid in MCT group were significantly higher than that in the corn oil group.

The effects of dietary buckwheat vegetables on the in vitro HMG-CoA reductase activity and lipids profiles of serum and liver in rats were evaluated . Buckwheat vegetables were cultivated in the range of 1-15cm of the plant height and dried. The content of rutin in the dried vegetables did not varied largely with the differences in the height of the vegetables. The water extract from buckwheat vegetables activited in vitro HMG-CoA reductase, activity up to 150% of control. Male rats were fed on purified diets. supplemented with0.12% cholesterol, containing dried buckwheat vegetables(BWV, 5% of diet) or rutin 90.25% of diet) . Dietary BWV and rutin, compared with basal diet tended to decrease the concentration of serum cholesterol. The ratio of HDL-cholesterol to total cholesterol were higher slightly in the rutin -fed group than in the other groups. The concentration of serum triacylglycerol was lower markedly in the rutin -fed groups than in the control groups, and BWV group being intermediate . The concentration of liver cholesterol was lower significantly in the BWV group than in the other groups. The results show an effective cholesterol-lowering action of buckwheat vegetables in serum and liver of rats fed on cholesterolemic diets. and that the hypocholesterolemic effects of buchwheat vegetables re not likely to be due to the modulation of the cholesterol synthesis rate.

This study was carried out to investigate the clinical effects of Tongbiyeum(TBY) ₂on hyperlipidemia. The hyperlipidemia of rats was induced by feeding high cholesterol diet for 4 weeks. We checked serum lipids and body weight weekly for 4 weeks. After the termination of treatment, we measured liver weight and observed histopathological change. We compared result of TBY group with control group. Thereafter, we made a study of 37 hyperlipidemic patients who visited us, the oriental medical center Daejeon and cheongju of Daejeon University, from November, 2001 to April, 2002. After administering TBY for 1 month, we followed up their total cholesterol, triglyceride and HDL-Cholesterol levels. The results were as follows; TBY treatment inhibited the liver weight gain induced by high cholesterol diet as compared with control group. TBY treatment inhibited lipid droplet accumulation and apoptotic change in liver as compared with control group. TBY treatment significantly inhibited the increasing of serum triglyceride and total cholesterol levels induced by high cholesterol diet as compared with control group but not affect HDL-cholesterol level. After administering TBY, the serum total cholesterol, triglyceride and LDL-cholesterol levels of hyperlipidemic patients were decreased significantly. After administering TBY, the serum HDL-Cholesterol level of hyperlipidemic patients had no significant changes. According to above mentioned results, we can infer that TBY has hypolipidemic effect to be applicable to artheriosclerosis.
