  • The aim of this study was to investigate the effect of bread supplemented with silkpeptide and cholesterol of on the lipid metabolism in rats. When a rats were fed bread supplemented with silkpeptide and cholesterol, their net weight tended to decrease compared with the control. Although the food intake was increased, this was not significant., but the feed efficiency ratio was substantially decreased. The total and LDL-cholesterols were decreased, but the DHL-cholesterol was increased. The HDL-cholesterol to total cholesterol ratio and level of triglyceride were substantially increased. The atherogenic index was decreased when rats are fed bread supplemented with silkpeptide and; thus, would show an improvement in the effect of high-cholesterol symptoms.

  • Effects of garlic on hypocholesterolemia, anticoagulation and hypoglycemia were studied in the present experiments using male rats. The results were summarized as follows. 1. The supplementation of $2{\sim}4%$ garlic to 2% cholesterol diets did not affect food intake and weight gain in male rats. 2. Rat's groups fed the diets supplemented with $2{\sim}3%$ garlic (C.D.E.F) to 2% cholesterol diet (B) decreased serum total cholesterol levels by $16{\sim}32%$, triglyceride levels by $18.6{\sim}26.8%$ and ${\beta}/{\alpha}-lipoportein$ rations by $42{\sim}58%$, but increased HDL-cholesterol levels by $29{\sim}65%$ as compared to B group, and so the author assumes that garlic supplementation exerts hypocholesterolemic effect on cholesterol - fed rats because of the increase of HDL and HDL - cholesterol levels. 3. Rat's groups fed the diets supplemented with $2{\sim}4%$ garlic (C.D.E.F) to 2% cholesterol plus 0.25% bile salt diet (B) increased whole blood coagulation times, prothrombin times and fibrinolytic activities, but decreased plasma fibrinogen levels as compared to B group, and so the author assumes that garlic supplementation exerts anticoagulative effect because of the inhibition of fibrinogen synthesis in male rat's liver. 4. Rat's groups fed the diets supplemented with $2{\sim}4%$ garlic (B.C.D.E) to standard diet (A) decreased serum glucose levels by $1{\sim}24%$, but increased serum insulin concentrations by $0.5{\sim}3.0$ times as compared to A group, and so the author assumes that garlic supplementation exerts hypoglycemic effect because of the increase of serum insulin levels by stimulation pancreatic secretion of insulin from ${\beta}-cells$ in the islets of Langerhans.

  • The effect of heat treatment (autoclaving at $100^{\circ}C$ for 30 minutes) of soybean on the cholesterol contents in the brain and aorta of the albino rat was studied. The subjects were 72 young male rats and divided into 12 groups by diet and periods. Experimented periods were 5, 15 and 30 days, diet standard are raw soybean, soybean diets heated at $100^{\circ}C$ and $120^{\circ}C$ respectively, and each diet was prepared to contain 14g protein and 400 Kcal per diet 100g. After corresponding treatment, the cholesterols in the brain and aorta were determined. The results are summarized as follows: In the brain, total, free and ester cholesterol contents of each group are not remarkedly different from those of control group, in the experimental periods. In the aorta total and free cholesterol at $100^{\circ}C$ and $120^{\circ}C$ than those of control group, but there is no significant difference among groups fed for 15 or 30 days, and the ester cholesterol has no regular tendency. It seems that the heat treatment at $100^{\circ}C$ and $120^{\circ}C$ of solybean has no effect on the cholesterol contents of the brain and aorta.

  • In order to observe the bioactivity of ovariectomized rats, ovariectomized group (Ovx), nonovariectomized group (Sham), ovariectomized Vitamin C-treat group (Ovx+Vit C), ovariectomized Vitamin E-treat group (Ovx+Vit E) and ovariectomized Vitamin C+Vitamin E-treat group(Ovx+Vit C+E) were made. Lipidperoxides of liver and kidney, serum total cholesterol and HDL-cholesterol were investigate as follows. Lipidperoxides of liver and kidney in Ovx group were 1.78 times and 1.61 times increased compared to Sham group respectively. But, they were significantly decreased in Ovx+Vit C group, Ovx+Vit E group, Ovx+Vit C+E group compared to Ovx group. Serum total cholesterol in Ovx group was increased 2.57 times compared to Sham group. Injections of each substance such as ascorbate, tocopherol, mixture (C+E) make data of Cholesterol become low. When especially Vit C is injected, the data of cholesterol lowed by about 94%. Serum HDL-cholesterol in Ovx group decreased 36.7% compared to Sham group. And as the result of the measurement of SOD, Catalase, and GPx which are antioxidant enzyme, SOD and Catalase activities in Ovx group much higher than in Sham group. Based on the results, it is supposed that more produced free radicals increased antioxidant enzyme. And it is also thought that vitamin can inhibit aging by reducing antioxidant enzyme.

  • In this study rats in fasting or fed protein free restricted diet including only fat showed much lowered level of serum cholesterol and triglyceride accompanied by utmost weight loss and high level of blood urea nitrogen indicated the tissue degradation, especially in liver with signs of damage or necrosis of hepatic parenchymal cell leading to elevated glutamic pyruvate transaminase value and to death. Rats fed only perilla oil in starvation or as fat source in normal diet dropped down the level of serum cholesterol and triglyceride compared to beef tallow fed rat. But with evidence of glutamic pyruvate transaminase values which was significantly elevated long term ingestion of perilla oil is likely to cause the lesion or any damage of hepatic function.

  • To study effects of wild garlic on components of lipid and protein, blood glucose level, and cholinesterase activity in rat's serum, Sprague-Dawley strain of 40 male rats are divided into 5 groups which are Normal, Control, A, B, and C group. Normal group is fed only Basal diet, and Control group is fed Basal diet and 0.5ml/day of 2.5% cholesterol solution, In addition to a diet of control group, A group is fed 25% wild garlic flour, B group 0.5ml/2day of concentratded wild garlic juice, C group 0.5ml/2day of concentrated ethanol extract of wild garlic, After 8 weesk the rats were fasted for 12 hours, and then decapitated to collect blood. The results of analysis of the rat's serum were summarized as follows, 1. Wild garlic diet, specially ethanol extract has an influence on decreasing the level of total cholesterol and blood glucose in rat's serum, 2. HDL-cholesterol and phospholipid content of rat's serum are increased by wild garlic diet. Therefore I think that wild garlic is good food for preventing development of atherosclerosis and diabetes.
