Magnesium(Mg) plays an important role in lipid metabolism and Mg deficiency but Ca sufficiency Increases serum cholesterol and triglyceride. The relationships of serum Mg, Ca, Ca/Mg ratio with lipids was examined in 79 female college students in Choong-Nam area. Subjects were divided into underweight, normal and overweight groups according to their BMI. The average age, body weight, height and BMI were 21.9yr, 55.9kg, 158.5cm and 22.62kg/$m^2$ respectively. Height was not different between groups. Serum cholesterol and LDL-cholesterol concentrations were significantly lower in the underweight group than other groups. BMI had positive correlations with LDL-cholesterol, atherogenic index (AI) and LDL-cholesterol/HDL-cholesterol ratio(LPH), and negative correlations with HDL-cholesterol/total cholesterol ratio. Serum minerals (serum Mg, Ca, Ca/Mg ratio) and serum lipid concentrations were not significantly different between groups. However, there was a tendency of increasing serum Mg level with increasing serum HDL-cholestrol, HDL-cholesterol/total cholesterol ratio and decreasing serum LDL-cholesterol, LPH, total cholesterol/HDL-cholesterol ratio(TPH) and AI. And there was a tendency of increasing serum Ca level with increasing serum HDL-cholesterol/total cholesterol ratio and decreasing serum triglyceride, LDL-cholesterol, LPH, TPH and AI. And there was a tendency of increasing serum Ca /Mg ratio level with decreasing triglyceride, serum LDL-cholesterol and TPH. This study was limited within serum levels of minerals (serum Mg, Ca and Ca/Mg ratio), serum lipids concerned with CHD, therefore I hope there will be wider efforts to consider about the dietary levels of minerals for presentation of the connection between dietary Mg, Ca and serum lipids.

To examine the effects of pomegranate on cerebral blood flow and obesity, we observed regional cerebral blood flow in normal rats, as well as body weight, serum total cholesterol, serum HDL-cholesterol, serum LDL-cholesterol, serum triglycerides, serum total lipids, serum phospholipids and serum free fatty acid levels in rats fed a high fat diet. The results were as follows. Pomegranate seed extract significantly increased regional cerebral blood flow and the peel extract increased regional the cerebral blood flow in a dose dependent manner. In addition, the pomegranate extracts(seed, peel, juice) decreased body weight, serum total cholesterol, serum LDL-cholesterol, serum triglycerides, serum total lipids, serum phospholipids and serum free fatty acid levels, and increased serum HDL-cholesterol in the rats fed a high fat diet. More specially the seed extract significantly decreased serum total cholesterol, serum triglycerides and serum phospholipid levels.

The effect of milk in low and high cholesterol diet was invesigated on serum cholesterol metabolism and lipid contents of serum, aorta, liver of rats. Weanling male Sprague-Dawley rats were divided into low(0.01% w/w) and high(1.01% w/w) cholesterol-diets groups. Low cholesterol groups subdivided into four groups ; control group was given water and three milk groups were given low heat milk(LM), ultra-high heat milk(HM), and powder milk(PM), respectivily, instead of water. High cholesterol groups were consisted of three groups ; control, LM, and HM groups. After feeding these experimental diets for six weeks, lipid levels were measured in serum and tissure and dried feces were analyzed for neutral and acidic sterols. Results obtained from this study are as follows : 1) Nutrient intakes, body weight gains and aorta weights did not differ among groups, but liver weights were higher in high cholesterol fed rats than low cholesterol fed rats. 2) Serum protein contents were increased independently by intakes of high cholesterol and milk. 3) Serum total cholesterol and triglyceride levels were increased but phospholipid levels and HDL-cholesterol/total-cholesterol ratios were decreased by high cholesterol in diet. And milk supplementation decreased serum total cholesterol and triglyceride levels but increased phospholipid levels and HDL-cholesterol/total-cholesterol ratios. 4) Contents of cholesterol and triglyceride in aorta and liver were elevated by dietary high cholesterol and lowered by consumption of all three types of milk. 5) Levels of cholesterol and triglyceride among serum, aorta and liver were highly correlated (r=0.7-0.9, p<0.001). 6) Fecal excretion of total sterols was three times high in high cholesterol group, compared with low cholesterol groups and were increased about 20% by milk consumption. 7) The effects of milk were more pronouncely shown in low cholesterol groups and mostly confined to LM and HM groups, rarely shown in PM group. It is concluded from the present study that milk had the hypolipidemic as well as hypocholes terolemic effect, which appears to be mediated through increased fecal bile acid excretion. But the effect is likely to be shaded by excess consumption of dietary cholesterol and was almost absent in powder milk.

To estimate annual changes in age adjusted mean of serum cholesterol and cholesterol intake in Korea during the past years, data from 21 literatures regarding for serum cholesterol level of Korean or National Nutrition Survey Reports from 1962 to 1995 were extracted for this study. Age standardization for mean serum cholesterol level was adjusted being based on Korean population composition in 1995. Mean of Korean serum cholesterol level depicted an increasing tendency from 1962 to 1995. Magnitude of changes in mean of serum cholesterol was big in the age old groups over 60th decade, but sex difference in the pattern was not observed. The estimated mean cholesterol intake was higher in the urban population than those of rural's and it increased linearly from 1969 to 1995. Major food sources for cholesterol were egg(39.3%), anchovy(8.3%), seafoods(35.2%) meat(13%) in 1995. From the results, it was estimated that mean serum cholesterol and daily cholesterol intake of Korean would be 178 mg/dl and 278mg/day in 1995, respectively.

Recently, a lot of epidemiological studies revealed that low HDL-cholesterol level was a better predictor of risk for coronary heart disease than total cholesterol. This study investigated the anthropometric parameters, clinical blood indices, and dietary factors influencing serum HDL-cholesterol level by using a cross-sectional study for Korean female college students. The subjects were 94 female college students. They were divided into three groups according to their serum HDL-cholesterol levels, low HDL-cholesterol (<50 mg/dL, n=20), medium HDL-cholesterol (50 $\leq$, < 60 mg/dL, n=39) high serum HDL-cholesterol groups (60 $\leq$ mg/dL, n = 35). This study examined their demographic data and dietary intake throughout a questionnaire. Clinical blood indices were measured using an automatic blood chemistry analyzer (Selectra E), after 12 hours of fasting. BMI, body weight, fat mass, and waist circumferences were significantly increased according to low serum HDL-cholesterol levels. Serum lipid analysis showed a significantly higher level of TG, LDL-/HDL-Ratio, atherogenic index in the low HDL-cholesterol group. Serum levels of GPT, uric acid and alkaline phosphatase in the low HDL-cholesterol group were significantly higher than in the other group. The average consumption of energy was 1627 kcal and 77.76% of estimated energy requirement (EER). The mean ratio of calories from carbohydrate: protein: fat was 57:15:28. The low HDL-cholesterol group was significantly higher than the other groups in eggs, fat and oils consumption. Interestingly, milk and diary products consumption of low HDL-cholesterol group was half (p < 0.05) of those of the other groups. In conclusion, serum HDL-cholesterol levels appeared to be decreased by increasing BMI, fat mass, waist circumference, and serum TG level. In addition, some dietary factors seemed to be related to serum HDL-cholesterol levels. However, further research is needed to elucidate the exact relationship between serum HDL-cholesterol level and dietary factors.

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 cholesterol and fatty acid levels in serum and liver were compared in 4-week-old Sprague-Dawley male fed by addition of polymannuronate (M, 5.0％), polyguluronate (G, 5.0％), and polymannuronate and polyguluronate (MG, 2.5％ to each) with by addition of cholesterol (1.0％). Feed efficiency by the addition of M, MG, and G was lower than cholesterol fed group (p＜0.01). The liver weights were less in M, MG, and G fed groups than in cholesterol fed group (p＜0.01). Triglyceride levels in serum and liver were 58.2∼77.4％ and 51.5∼65.5％ lower in M, G and MG fed groups than cholesterol fed group, respectively. Total-, LDL-, and free-cholesterol levels in serum and liver in M, MG, and G fed group were significantly lower than cholesterol fed group. The cholesterol levels were the most reduced in M fed group. However, HDL- cholesterol level in serum was increased in M, MG, and G fed group (p＜0.01). The of polyene levels were 47％ higher in serum and 76％ in liver in M fed group than in cholesterol fed group. The activities of GOT and GPT were lower in M, MG, and G fed group than in cholesterol fed group (p＜0.01). Above the results demonstrate that supplementation of low molecular polymannuronate in diets improve physiologically lipid composition in serum and liver.

This study was to investigate the effect of zinc supplementation on serum cholesterol concentration of young women. Thirty healthy students were divided into Zn and placebo groups, and were orally given with zinc(50mg/day, 220mg as ZnSO4·7H2O) or placebo for 2 month (June 9-August 7, 1988). Changes of plasma zinc, serum total cholesterol, HDL-cholesterol (HDL-C), LDL-cholesterol(LDL-C) and total lipid were analyzed from the initiation to 1 month after the end of zinc supplementation at monthly interval. Plasma zinc, serum LDL-C content and LDL-C/HDL-C were significantly increased by zinc supplementation. Serum total cholesterol content tended to be increased by zinc supplementation but was not significantly different between the two groups. Serum HDL-C content was significantly decreased by zinc supplementation. Serum total lipid content was not different between the two groups during experimental period. Thus, in this study considering the effect of zinc supplementation on serum cholesterol concentration, we conclude that the effect of zinc supplementation on coronary heart disease may be negative.
