  • The purpose of this study was to examine the impact of isoflavones on lipid concentrations and hepatic LDL receptor mRNA level in growing female rats. Twenty four rats (body weight $75\pm5g$) were randomly assigned to one of two groups, consuming control diet or isoflavones supplemented diet (57mg isoflavones/100g diet). All rats has been fed on experimental diet and deionized water ad libitum for 9 weeks. The concentration of triglyceride and total cholesterol were measured in serum and liver. Serum HDL cholesterol was measured. Hepatic LDL receptor mRNA level was tested by RT-PCR. Supplementation of isoflavones did not affect weight gain, mean food intake and food efficiency ratio. Serum total cholesterol and non-HDL cholesterol of isoflavones supplemented rats were significantly lower than those of control rats (p<0.05). But hepatic cholseterol was not influenced by supplementation of isoflavones. Hepatic LDL receptor mRNA level not significantly different between control group and isoflavones supplemented group. Therefore, isoflavones may be beneficial on serum cholesterol and non-HDL cholesterol lowering in growing female rats.

  • The effects of the vegetable diet on the levels of the serum lipids, particularly the level of the serum total cholesterol which is most concerned with coronary heart disease (CHD) were investigated in 30 male SDA (Seventh Day Adventists) group and 30 male omnivorous group (control group). SDA participated in this study intaked relatively few animal origin foods whereas they intaked plant origin foods largely; they seldom or sometimes intaked meats, fishes, butter, margarine, beverages and coffee, but often unrefined cereals, legumes, vegetables and fruits. In the both systolic pressure and diastolic pressure, there was no difference between two groups. The levels of the serum total cholesterol, triglyceride and phospholipid were lower in SDA group than in the omnivorous group. Among them the difference was statistically significant in the level of the serum total cholesterol. HDL-cholesterol was more or less higher in SDA group than in the omnivorous group, but the difference was no significant. The result that SDA group had lower level of the serum total cholesterol than the omnivorous group suggested that that they might be less prone to CHD than the omnivorous group. Though this possibility, however, was derived from the fact of the lower level of serum total cholesterol of SDA group, it might by partly responsible for their habit that they never smoke and drink alcohols and coffee.

  • Green tea, which has high polyphenols amount, is thought to have hypocholesterolemic effects. The present study was performed to further examine the hypocholesterolemic action of green tea, especially (-) epigallocatechin gallate (EGCG) for its effect on diet-induced hypercholesterolemia in rats. Male Sprague-Dawley rats (n=15) were fed a green tea-free diet (control), $1.0\%$ green tea catechin (catechin) or $0.5\%$ green tea catechin EGCG for seven weeks. Hypercholesterolemia was induced by adding $1\%$ cholesterol and $0.5\%$ cholic acid to all diets. There was no difference in food intake and body weight gain among the groups. The green tea EGCG treatment led to a significant improvement in plasma levels of total cholesterol, low density lipoprotein (LDL)-cholesterol and high density lipoprotein (HDL)/LDL ratio (p<0.05). There was no significant effect on the plasma HDL-cholesterol level. The catechin treatment led to a 4.19-fold increase in the LDL-receptor mRNA level compared to the control, but the EGCG treatment did not affect the hepatic LDL-receptor mRNA level. Our results suggest that when blood cholesterol level is down-regulated by green tea EGCG, the LDL receptor gene-independent pathway may dominate the hypocholesterolemic action of EGCG.

  • In order to study the effects of Guibitanggamibang on blood pressure and hyperlipidemia, experimental study were performed on hypertension in normal and SHR rats, and on hyperlipidemia induced by Triton WR-1339 in normal rats. Also the level of total cholesterol, triglyceride, LDL-cholesterol, HDL-cholesterol, phospholipid and transaminase(GOT, GPT) were measured. The results are summarized as follows: 1. After Guibitanggamibang was given to normal rats, the results showed that inhibitory effects on blood pressure and heart beat were not statistically significant. 2. After Guibitanggamibang was given to SHR rats, the results showed that inhibitory effects on blood pressure were statistically significant. 3. In the model of hyperlipidemia induced by 2% cholesterol food, Guibitanggarrubang had significantly-decreasing effects on total cholesterol, triglyceride, HDL-cholesterol, LDL-choleste rol, Transaminase(GOT, GPT) level in serum. 4. In the model of hyperlipidemia induced by Triton WR-1339, Guibitanggamibang had significantly-decreasing effects on total cholesterol, triglyceride, LDL-cholesterol, phospholipid, Transaminase(GOT, GPT) level in serum. 5. In the model of hyperlipidemia induced by Triton WR-1339, Guibitanggamibang had no significant effects on HDL-cholesterol level in serum. These results show that Guibitanggamibang(歸脾湯加味方) has significant inhibitory effects on blood pressure and hyperlipidemia and that it could be clinically applied for hypertension and hyperlipidemia.

  • 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.
