This experiment is carried out to study effect of choline-deficient diet on serum and liver lipid contents of male rats. The experimental animals use 36 male Sprague-Dawley rats weighing about $100{\pm}3g$. They are classified into 7 groups and fed to experimental diets which are composed of 0.8% choline-supplement of deficient diets in addition to 14% corn oil, 14% corn margarine and 14% lipids mixed with 4% corn oil and 10% corn margarine, respectively. After feeding for 4 weeks, I measure lipid concentration of serum and liver, and the result are as follows. 1. The choline-deficient diet group decreases slightly the rates of weight gain and feed efficiency as compared with those of the choline-supplement diet group, but increases liver weight. 2. The choline-dificient diet group decreases the serum concentrations of total cholesterol (TC), free cholesterol, HDL-choelsterol, VLDL, LDL-cholesterol and phospholipid (PL), but increases the contents of triglyceride and the ratios of cholesterol/HDL-cholesterol and triglyceride/PL, and indicates no remarkable-difference in the ratio of TC/PL. 3. As compared with the choline-supplement diet group, the choline-deficient diet group contains the higher liver contents of total lipids, free cholesterol and triglyceride, and gives little difference in the liver contents of total cholesterol and phospholipid(PL), and presents the higher ratios of VLDL, LDL-cholesterol/HDL-cholesterol and TG/PL in the liver.4. In the choline-deficient diet group, the coutents of serum and liver lipid is not influenced by the kind of dietary fat. On the other hand, the choline-supplemented diet group indicates a significantly lower content of phospholipid in the corn margarine-added diet group than in the corn oil-added diet group. As aforementioned results, I think that the choline-deficient diet induces fatty liver in male rats without relation to kind of fatty acid, and cholines-upplement diet with saturated fatty acid makes the more decrease of liver phospholipid than that with polyunsaturated fatty acid.

This study examined the effects of mulberry-leaf powder Tofu(MPT) on the anthropometric measurements, bone mineral density(BMD), biochemical markers of bone turnover, serum lipid levels of and macrominerals status in 30 female university students living in Choongnam with low dietary Ca intake was low(mean daily $intake=524.66{\pm}21.47$ mg/day). The subjects received the MPT supplemented(100 g/day) for 4 weeks. The nutrient content per 100 g MPT was 84.10 kcal(energy), 8.98 g(protein), 0.53 mg(fiber), 211.33 mg(Ca) and 1.59 g(fat). Anthropometric measurements, 24-hour dietary recall, carpus BMD using DEXA, select BMD biomarckers(serum alkaline phophatase activity, osteocalcin, urinary deoxypyridinoline), serum protein levels, albumin, and glucose levels, lipid profiles(cholesterol, triglyceride, HDL-cholesterol, LDL-cholesterol) and serum macrominerals(Ca, Ca/P ratio, Mg) were analyzed before and after MPT supplementation. Following MPT supplementation, there was no significant differences in anthropometric measurements, nutrient intakes, carpus BMD, serum alkaline phosphatase activity, osteocalcin, and urinary deoxypyridinoline, serum levels of protein, albumin, and glucose or lipid profiles with AI, HTR, LHR and CRF. However, there were significant increases in dietary calcium as well as decreases in serum triglycerides with MPT supplementation. Although further research is needed, these results that regular intake MPT could prevent bone and cardiovascular diseases.

The nutritional survey and blood sampling was conducted from May 23 to 27, 1971, in order to investigate the state of the nutritional intake in relation to blood contents of rural women. This survey covered a total of 47 women residing in Youngam-gun, Cholla-namdo, Korea. The daily diet of these subjects was observed by 24-hour recall method and weighing method for 3 days and hemoglobin (Hb), hematocrit(Hct), mean corpuscular hemoglobin concentration (MCHC), serum protein, serum albumin, A/G ratio, serum iron, total iron binding capacity (TIBC), transferrin saturation (TS), serum cholesterol and blood specific gravity (SG) were measured. The results were summarized as follows ; The rate of intake of vegetable foods was high, especially cereals, and that of animal foods was low, especially eggs and milk and milk products. The daily intake of niacin was sufficient, and the intakes of energy and iron were also tend to be adequate. On the contrary, the intakes of vitamin A, $B_2$ and C, calcium and protein were insufficient. The mean red blood cell number was $410.8{\pm}26.4{\times}10^{4}/mm^{3},$ the mean values of Hb, Hct and MCHC were $12.5{\pm}0.9gm%$, $37.5{\pm}2.4%$ and $33.2{\pm}0.5%$ thus the anemic prevalences were 21.3%, 12.8% and 93.6% comparing with the anemic criteria of WHO. The levels of serum protein and serum albumin were $7.1{\pm}0.4gm\;%$ and $4.3{\pm}0.3gm\;%$so the A/G ratio was indicated $1.6{\pm}0.2.$. The levels of serum iron and TIBC were $91.9{\pm}27.5{\mu}g/100ml and $297.5{\pm}31.4{\mu}g/100ml,$ so TS was calculated $31.2{\pm}9.7\;%$. The mean value of SG was $1.044{\pm}0.002,$ and the level of serum cholesterol was $164.3{\pm}25.4mg/dl$. In the relation between each of bloood content, Hb showed positive correlation not only with Hct but also protein at the level of significance of 1 per cent and 5 per cent, and protein also showed a positive correlation with serum cholesterol at the 1 per cent level of significance. In the relation between the nutrient intake and blood contents, vitamin C intake showed a positive correlation with Hb, serum protein and serum iron at the level of significance of 1 per cent, iron intake also showed a positive correlation with serum iron and serum cholesterol at the same significant level, and protein intake showed a positive correlation with serum iron at the at the level of significance of 5 per cent.

This study was designed to examine the effect of ${\omega}-3$ fatty acid, linlenic acid, EPA, DHA on serum lipid and cytokines of male rats(Sprague-Dawley). Animals of 3 groups were administrated perilla oil, salmoon oil, and tuna oil of 0.4 $m{\ell}/day$ for 8 weeks respectively. These oils were used for a source of linolenic acid, EPA and DHA. ${\omega}-3$ polyunsaturated fatty acid decreases significantly body weight, serum $PGE_2$ content and serum cytokines content of the rat, and increases internal organs weight, specially liver weight and serum HDL-cholesterol level of the rat. In the results, authors propose to use perilla oil for source of effective ${\omega}-3$ poly-unsaturated fatty acid(linolenic acid) to Prevent cardiovascular and immune diseases.

The purpose of this study was to investigate the effect of enzyme-treated radish (Raphanus sativus L.) leaves on lipid metabolism in rats fed a high fat diet. Rats were divided into four experimental groups which were composed of a high fat diet group (HF group), a high fat diet with 10% radish leaf powder-supplemented group (MA group), a high fat diet with 5% enzyme-treated radish leaf powder-supplemented group (MB group) and a high fat diet with 10% enzyme-treated radish leaf powder-supplemented group (MC group). Total dietary fiber content of enzyme-treated radish leaves were greater than untreated radish leaves. Body weight gain and food efficiency ratio (FER) of the HF group increased compared to the MA, MB and MC groups. The serum total cholesterol, LDL-cholesterol and atherogenic index contents in the radish leaf powder-supplemented groups were lower than that of the HF group, while those values for the MB and MC groups were significantly lower than that of the HF group. The serum HDL-cholesterol contents of the MB and MC groups increased compared to the HF group. The hepatic triglyceride contents of the MA, MB and MC groups decreased compared to the HF group. In fact, the hepatic triglyceride contents of the MB and MC groups were significantly lower than the MA group. The hepatic total cholesterol contents of the MB and MC groups significantly decreased compared to those of the HF group. The fecal total cholesterol contents of the MA, MB and MC groups significantly increased compared to those of the HF group. These results indicate that supplementation with enzyme-treated radish leaves increase the useful fiber contents. Furthermore, it may have a pronounced impact on lipid metabolism of serum and liver in rats fed a high fat diet.

This study was carried out to investigate the dietary effects of chitosan mixture (CM), an herbal medicine mixture with Sukjihwang (HS), and CM containing HS (CHS) on obesity in an induced obese model of rats fed high-fat only (HF), in which supplemented diets of 5% CM (HCM), 5% HS (HHS), or 2.5% CM-2.5% HS (HCH) was tested for 6 weeks. Body weight gains, obesity indexes, and body fat contents in the experimental groups (HCM, HHS, HCH) were decreased compared with HF group. The levels of serum triglyceride, total lipid, total cholesterol and LDL-cholesterol in the experimental groups were markedly decreased, however HDL-cholesterol levels in the experimental groups were slightly increased compared with HF group. In addition, although serum ALT and AST activity, and relative organ weights were lower than those of HF group, serum albumin contents were not significantly different in all experimental groups including the normal control group (NC). In conclusion, there are improved effects on obesity in the obese model of animals with all experimental diets supplementations, and the improvement degrees on obesity depend on the content and compositions of the herbal medicine mixture. Further study is needed on the anti-obesity mechanism of these diets.

The present study has been undertaken to investigate the effect of plantaginis semen extract on lipid composition and activities of several enzymes in lard administrated rats. Forth male rats of Sprague-Dawley strain with average weight of 130$\pm$10g were divided into four groups[basal diet(BD)], basal＋plantaginis semen(BP), basal＋lard(BL) and basal＋plantaginis semen＋lard(BLP). Lard administrated groups showed increase in weight gain and that of BLP group significantly increased. Feed intake showed no significant differences with lard administration. The weights of liver, kidney and heart of the rat were not affected by plantagins semen and lard administration. Serum and liver triglyceride and cholesterol contents significantly increased compared to BD group but significantly decreased by the addition of plantaginis semen extract(BLP group). Serum and liver phsophlipids decreased in lard administrated group but effectively restored by administration of plantaginis semen extract. HDL-cholesterol content significantly decreased in lard-fed group and somewhat increased in plantaginis semen extract group. Serum aminotransferase, lactate dehydrogenase activities significantly increased in lard fed group but addition of plntginis semen extract significantly decreased the enzyme activities compared with that of lard administrated group.
