  • The feeding effects of Herba hottuynia extracts on the lipids profiles and the content of TAB-reactive substances were evaluated in rats fed a high cholesterol diet. Hot water or ethanol extracts of the dried leave were evaporated and lyophilized . The experimental animals wer edevided to four groups and fed the following diets for 4 weeks : BAsal (cholesterol-free diet), CHOL(cholesterol-enriched diet),CW (cholesterol plus water extract) and CE(cholesterol plus ethanol extract). Dietary cholesterol increased significantly the activities of serum GOT and GPT, but the extracts feeding (0.5% of diet) did not influence the activities induced by dietary cholesterol. Although dietary cholesterol increased significantly the concentrationof serum andliver cholesterol, it tended to decrease the concentation of serum triglycerides. CHolesterol feeding had a lowering effect on the lipid peroxidation value of serum, but not inliver.Furthermore, the extracts feeding, especially water extract, decreased markedly the liver peroxidation value. The results suggest that Houttyunia cordata extracts have an in vivo antioxidant effect, judged from the TBA value in the liver rats fed a high cholesterol diet.

  • Purpose: The aim of this study is to examine the effects of egg consumption and suggest proper guidelines for consumption of eggs by determining the relationship between eggs and cholesterol. Methods: Literature review was conducted on the relationship between nutritional, functional properties of eggs and serum cholesterol, as well as cardiovascular disease. Results: Eggs, which are a good protein food with complete amino acid composition, contain vitamin A, riboflavin, vitamin $B1_2$, folic acid, vitamin D, vitamin E, vitamin K, calcium, iron, choline, selenium, ${\beta}$-carotene, lutein, zeaxanthin, etc. However the egg yolk has a high cholesterol content, which is associated with chronic diseases, including heart disease and hypertension. As a result, its intake is subject to regulation. Outbreak of heart disease by yolk intake can show different results depending on the characteristics of the subjects, amount of egg intake, and the implications of other foods eaten. It is difficult to determine whether eggs are beneficial, as they are the main supplying source for other major nutritive elements as well. Several research studies insist that when cholesterol intake increases by 100 mg, the level of serum cholesterol increases by 2.2~4.5 mg/dL and when serum cholesterol increases by 1%, the risk of heart disease increases by 2%. This indicates that a large intake of eggs can increase the risk of heart disease. Although the cholesterol of egg yolk and serum cholesterol are correlated, it is insufficient to conclude that only cholesterol and not other components are related to heart disease. In fact, other components in egg such as various unsaturated fatty acids and phospholipids could be related as well. Rather than concluding egg as a 'good' or 'bad' food according to its cholesterol content, it is important to define egg as a part of dietary patterns. Conclusion: Generalizing an indiscriminate and uniform amount of egg intake for all seems inadequate. However, patients with diabetes or heart disease should pay particular attention to the amount of egg intake. As for the norm, eating egg with vegetables as a substitute for other animal products seems beneficial.

  • This study was conducted to investigate the effects of caffeine on lipid and mineral content in the serum of rats given a caffeine free diet(FC), a low caffeine diet(LC), a medium caffeine diet(MC), a high caffeine diet(HC) or a super-high caffeine diet(SHC) for 5 weeks. Thirty male Sprague-Dawley rats(body weight, $110{\pm}0.3$ g) were blocked into 5 groups and fed diets with or without pure caffeine. Caffeine intake models showed a lower mean-weight gain, food intake and food efficiency in the high caffeine diet groups(MC, HC and SHC groups) than the groups receiving a caffeine free or low caffeine diet(FC and LC groups). Serum total lipid, total cholesterol and LDL-cholesterol levels decreased, but the serum HDL-cholesterol level increased according to the increase in caffeine intake. Serum total lipid, HDL-cholesterol and serum triglyceride were significantly lower in the HC and SHC groups than the FC group. All of the serum minerals decreased as caffeine intake increased. Serum iron, calcium, magnesium and phosphorus significantly decreased in the HC and SHC groups compared to the FC group. Caffeine intake was associated with less weight gain and reduced serum total cholesterol, triglyceride and total lipid. The results suggest that rats fed high amounts of caffeine may be susceptible to osteoporosis due to their low levels of calcium, magnesium and phosphorus.

  • This experiment was conducted to investigate the dietary effect of garlic powder (GP) and copper (Cu) on laying performances and the cholesterol content and quality characteristics of eggs during storage in laying hens. A total of one hundred and eighty, 50-wk-old, Hy-Line Brown layers were divided into 6 groups with 3 replicates per group (10 layers per replicate) and fed one of six diets containing GP 0%, GP 1%, GP 3%, GP 5%, Cu 200 ppm, or GP 3%-Cu 200 ppm for 5 wks. There were no differences in the laying performances and feed intakes bertween treatments. Eggshell strength, eggshell thickness and yolk color were also not affected by feeding of GP and Cu. With increasing dietary GP, Haugh unit was linearly increased after 2 wk of storage (p<0.05). The levels of serum total cholesterol in hens fed diets containing GP or Cu were lower than that of the control (p<0.05), but high density lipoprotein-cholesterol was not influenced by dietary GP or Cu. The content of egg yolk cholesterol from hens fed diets containing GP or Cu was significantly decreased from that of the control, except for the GP 1% group. Based on the results of this experiment, the decrease of Haugh unit during storage was alleviated by feeding of GP. The feeding of GP or Cu alone and in combination altered the cholesterol fractions in serum and reduced the content of egg yolk cholesterol in laying hens.

  • This study examined the effects of 2% Lycii fructus powder (LFP) supplementation on lipid metabolism in rats. Male Sprague-Dawley rats were administered 1% cholesterol and 0.25% sodium cholate to induce hypercholesterolemia. Then, 40 rats were divided into four diet groups: a normal diet group (NC), high cholesterol diet group (HC), normal diet plus 2% Lycii fructus powder (NC-LFP) group, and high cholesterol diet plus 2% Lycii fructus powder (HC-LFP) group. The HC group presented higher growth rates and liver weights than NC and NC-LFP however, growth rates and liver weights in the 2% LFP administered groups gradually decreased. HC also showed increased serum triglyceride, total cholesterol, free cholesterol, and LDL-cholesterol levels and decreased atherogenic index values, HDL-cholesterol, and phospholipid levels, whereas LFP group showed decreased serum triglyceride, total cholesterol, free cholesterol, and LDL-cholesterol levels as compared to HC. There were no differences in serum triglyceride, phospholipid, LDL-cholesterol, HDL-cholesterol, and free cholesterol concentrations between the normal diet groups (NC and NC-LFP). The high cholesterol diet groups (HC and HC-LFP) had significant increases in serum alanine aminotransferase (ALT), asparate aminotransferase (AST), alkaline phosphatase (ALP), and lactate dehydrogenase (LDHase) activities. And the 2% LFP administered groups had lower hepatic concentrations of total cholesterol and triglycerides than the HC groups. Overall, the results suggest that Lycii fructus powder has hypochloesterolemic effects by reducing serum and liver cholesterol contents.

  • This project was to compare the effects of consuming diets incorporating soybean oil , canola oil, ad palm oil on blood serum lipid patterns and fecal fat excretion in healthy human adults. The project was composed of three studies that were run concurrently . Each study was composed of a 4-day pre-trial period and two , 14-day experimental periods arranged according to a cross-over design. During the pre trial period, subjects were allowed to eat self-selected diets. During the experimental period , subjects were asked to eat constant, laboratory controlled diets in which sources of dietary fat varied . Thirty healthy , young adult subjects were fed a laboratory controlled diet incorporating soybean oil, canola oil, and palm oil. Test oils provided approximately 20% of the total dietary calories form all sources. Total dietary fat from all sources was approximately 30% of consumed calories. The highest serum total cholesterol , LDL cholesterol, VLDL cholesterol , and triglyceride values occurred when pam oil diets were eaten. However, feeding on palm oil diets resulted in the same HDL cholesterol content as with soybean oil or canola oil diets. Soybean oil diets produced numerically lower blood serum total cholesterol , LDL cholesterol, and triglycerides, and numerically higher HDL cholesterol and VLDL cholesterol than did those with canola oil. Fecal fat excretion was numerically lower with soybean oil diets than with canola diets. The highest fecal fat excretion occurred when palm oil diets were eaten.

  • In order to confirm whether or not Acacia leaf inhibits the increase of serum total cholesterol content of rabbits administered with cholesterol, this paper is conducted. Thirty rabbits were equally divided into three groups: A, B and C. The group A was fed with the stock diet only throughout the experimental period of 42 days. The group B was fed with the stock diet and cholesterol for the first 21 days and then Acacia leaf was given to the rabbits in addition to the above diet for the remainder of the experimental period. The group C was fed with the stock diet, cholesterol and Acacia leaf for the first 21 days and then the Acacia leaf was removed from the diet for the latter part of 21 days. The results of the serum total cholesterol determination of each group were illustrated in the tables, 1-11, and figure 1. From the data, therefore, following conclusion might be drawn: 1. The Acacia leaf inhibits the increase of serum total cholesterol of rabbits administered with cholesterol. 2. It is not clear whether Acacia leaf expedites the excretion of the metabolites of the given cholesterol or blocks the transfer of the absorbed cholesterol into the blood stream.
