The present study undertaken to investigate the interrelationship among their regular dietary fatty acid intake, body fat content(BFC), and plasma lipid fractions(PLF) of middle-aged Korean women. Forty-nine women (age 30 to 49) participated in this study in which the aim was to determine their total nutrient intake per day, BFC and PLF, and to analyse the intercorrelations of these. Strong correlation was seen among their body mass index, mid-upper-arm-circumference, and BFC which were positively correlated with plasma total lipids(TL) and triglycerides(TG). Dietary myristic acid and lauric acid were positively correlated with both total cholesterol(TC) and LDL-cholesterol (LDL-C) in plasma. Palmitic acid, stearic acid, oleic acid, and total monounsaturated fatty acid(MUFA) were negatively correlated with HDL-cholesterol(HDL-C). Although dietary total saturated fatty acid (SFA) was not correlated with TC and LDL-C, it was positively correlated with TL and TG in plasma. However, dieary n-3 polyunsaturated fatty acid(PUFA) in regular Korean diet was not correlated with any of lipid fractions in plasma which might be due to the high ratio of n-6/n-3 in their diet. From the above results, it was concluded that plasma lipid fractions were modulated by their dietary nutrients, especially the types of the fatty acids. Dietary SFA and MUFA intake not PUFA are strongly correlated with LDL-C and HDL-C in the Korean diet This may relate to the frequency of coronary heart disease in the age group.

This study was performed to evaluate the effect of the herbal extract mixture of Cnidium officinale, Petasites japonicus and Coptis chinensis (CPC) on the lipids metabolism in mice with tyloxapol. ICR mice weighing between 30-40 g were divided into four groups: normal group, 600mg/kg tyloxapol injected group, $50\;{\mu}g/g$ CPC treated group 6h after tyloxapol injection (SAM1), and tyloxapol and CPC treated group (SAM2), respectively. Tyloxapol or CPC was injected intraperitoneally. Tyloxapol caused an elevation of total cholesterol (TC), triglycerides(TG), and LDL-cholesterol and a decrease of HDL-cholesterol. In addition, tyloxapol induced accumulation of lipid including cholesterol in both the liver and kidney. Serum levels of TC, TG and LDL-cholesterol were decreased whereas HDL-cholesterol was increased by CPC. CPC increased in HDL-cholesterol /total cholesterol ratio and lowered atherogenic index. The levels of TC, TG and LDL-cholesterol by CPC were rather lower in SAM2 than SAM1. CPC also inhibited lowering HDL-cholesterol by tyloxapol. CPC reduced lipid blots and cholesterol particles in both the deposition and size in the liver and kidney with tyloxapol. These results suggest that CPC might be expected to be beneficial for protection and treatment of hyperlipidemia by the disturbance of lipid metabolism.

Chrominum (cr) plays an important role in carbohydrate and lipid metabolism , and Cr deficiency impairs glucose tolerance and increases serum cholestero and triglyceride. The relationship of serum Cr with serum blucose and lipids was examined in 79 female college students in Choong-Nam areas. Subjects were divided into underweight , normal , and overweight groups according to their BMI. The average age, wiegth , height and BMI were 21.9yr, 55.9kg, 158.5cm and 22.6kg/$m^2$, respectively. Heights were not different between groups. Serum Cr and glucose concentrations werenot significantly different between groups. However, there was a tendency toward lowered serum Cr levels in under and over-weight groups. Serum cholesterol and LDL-cholesterol concentrations were significant lower in the underweight group than in other groups. BMI had positive correlation with LDL-cholesterol , AI and LPH , and negative corelations with HDL -cholesterol /total cholesterol ratio. Low serum Cr concentration was related to increased LDL-cholesterol and total cholesterol, and related to decreased HDL cholesterol in all groups . Therfore, serum Cr levels were lowered in abnormal weight groups and Cr may playan important role in coronrary heart diesease.

The effectsof garlic vinegar supplementation on body weight, blood blucose, and plasma triglyceride and cholesterol were investigated in streptozotocin -induced diabetic rats fed high-cholesterol(1%) diet for 4 wk. The garlic vinegar was made by fermenting 20% frsh garlic juice. There was no effect of garlic vinegar on body weight, plasma glucose or triglyceride concentrations in the diabetic rats. Plasma total -cholesterol concentrations were unaffected by garlic vinegarr supplementation. However, plasma LDL-cholesterol concentrations and atherogenic index were significantly lower in the diabetic rats supplemented with garlic vinegar diet than tin the cotnrol rats. The diabetic-rats supplemented with garlic vinegar not only had increased HDL-cholesterol levels but had decreased LDL-cholesterol. This alteration in the HDL/LDL-cholesterol ratio in the diabetic rats may decrease the risk of atheroscelrosis. Therefore, the over-all effect of garlic vinegar supplement may contribute to the antiatherogenic role in streptozotocin-induced diabetic rats.

The purpose of this study was to examine the impact of caffeine on lipid concentrations in ovariectomized rats. Forty-four rats (75${\pm}$5 g) were randomly divided into ovariectomy(ovx) and sham groups, each of which were randomly divided into two subgroups that were fed the control diet or a caffeine-supplemented diet (0.03%/diet). The experimental groups were classified into 1) sham-control, 2) sham-caffeine, 3) ovx-control and 4) ovx-caffeine groups. All rats had been fed on experimental diet and deionized water ad libitum for 6 weeks. Triglyceride concentration and total cholesterol were measured in serum and liver. Serum HDL-cholesterol was measured. Serum LDL-cholesterol and atherogenic index were calculated. Weight gain and food efficiency ratio were higher in ovx groups than in sham groups (p<0.05). Caffeine intake did not affect weight gain and food efficiency ratio. Mean food intake was significantly increased in ovx-caffeine group than other three groups. There were no significant differences in serum triglyceride, total cholesterol, HDL-cholesterol, LDL-cholesterol and atherogenic index between the control diet group and caffeine diet group. In addition, hepatic triglyceride and cholesterol level was unaffected by caffeine intake or ovariectomy. Therefore, we suggest that caffeine (0.03%/diet) intake may not have adverse effects on serum lipid level in ovariectomized rats.
