Objectives : The purpose of this study was to investigate the anti-atherosclerotic effects of 4 herbal formulas for Sasang constitutional medicine (Yeoldahanso-tang: YDHST, Yanggyeoksanhwa-tang: YGSHT, Cheongsimyeonja-tang: CSYJT and Taeeumjowi-tang: TEJWT). Methods : The antioxidant activities of herbal formulas were studied by measuring free radical scavenging activities on ABTS and DPPH. The inhibitory effects on LDL oxidation was evaluated by the formation of TBARS, REM and fragmentation of apolipoprotein B-100 (ApoB). Effects of herbal formulas on macrophage lipid accumulation were determined in native LDL and LPS co-incubated macrophages using Oil Red O staining. Results : The scavenging activities on ABTS and DPPH of herbal formulas were increased in dose-dependent manner (YDHST>YGSHT>CSYJT>TEJWT). Herbal formulas reduced the oxidation properties of LDL induced by $CuSO_4$. YDHST, YGSHT and CSYJT showed strong suppressive effect on LDL oxidation than TEJWT. In addition, YDHST, YGSHT and CSYJT significantly inhibited foam cell formation in LDL/LPS stimulated RAW 264.7 cells. Conclusions : These results demonstrate that YDHST, YGSHT and CSYJT have potentials on anti-atherosclerosis by antioxidative effect and suppressive effect on LDL oxidation.

Objective : It is known that Pueriaria lobata has an anti-osteoporetic effect, anti-cancer effect, anti-pyretic effect, and anti-diabetic effect. The aim of this study was to evaluate anti-obesity effect of Pueriaria lobata extract (PLE), and elucidate the effect of it on gene expression related to lipid metabolism. Method : The experiments were performed with the use of ovariectomized rats as estrogen-deficient obesity model. They were grouped NC (normal control), OC (estrogen-deficient control), PLH (100mg/kg of PLE), PLL (20mg/kg). PLE was orally administered for 6 weeks. Body weights and serum lipid level were estimated, and real-time PCR was performed to investigate the effect of PLE on gene expression in liver. Results : PLE decreased the body weight and serum cholesterol and triglyceride, but increased HDL-cholesterol. And PLE increased leptin, CYP27, CPT1, CYP8B1, ACAT2, LDLR, and SCD1, but reduced $PPAR{\gamma}$, PGC1A, HMG-CoA-R, ACAT1, SCD1, and APoB gene expression in liver tissue of rat with estrogen-deficient obesity. Conclusion : It is concluded that Pueriaria lobata reduced body weight, and its effect was expressed by regulation of gene expression related to lipid metabolism in rats with estrogen-deficient obesity.

In the previous symposium, authors reported about anti-atherogenic action of Panax ginseng, saying that red-ginseng powder increased serum HDL-cholesterol, decreased total cholesterol, TG, NEFA, in addition, decreased platelet adhesiveness. Later, Toyama group including me. reported that ginsenosides esp. $Rb_2$ enhanced HDL and decreased LDL. Also Matsuyama group and Kinki Univ. group reported that ginsenosides $Rg_1,\;Rb_2,$ etc. inhibited platelet aggregation. This paper will be divided into two parts: Experimental and clinical Experimental study; Using a highcholesterol-cholic acid-fed rats, effects of red ginseng extract and several ginsenosides on serum apoprotein-lipoproteins in relation to prostaglandins. Rats received $2\%$ cholesterol 1-1$\%$ cholic acid diet, ginseng extract or ginsenosides 2.5mg/100g/day for 9 days. Red ginseng extract, ginsenosides $Rb_2,\;Rc,\;Rb_1,\;and\;Rg_1,\;esp.\;Rb_2,$ increased HDL, apo-AI, Aii and $PGI_2,$ while they decreased LDL, apo-B and $TXA_2$. Clinical study: Effect of red ginseng powder on hyperlipidemia was observed. Long term administration of red ginseng powder manufactured by Office of Monopoly, Republic of Korea and offered by Japan-Korea Korean Ginseng Co., Kobe, at the dose of 2.7 g/day, was performed in patients with hyperlipidemia up to 4 years. The significant increase in serum HDL-cholesterol and also the significant decrease in total cholesterol, atherogenic index, TG, NEFA and lipoperoxide was observed with 3-48 month administration of red ginseng. Conclusions: Red ginseng and ginsenosides improved hyperlipidemia in rats and in man, with the improvement of blood apoproteins, lipoproteins and prostaglandins in experimental hyperlipidemic animals.

Background: Inorganic arsenic is a human carcinogen that can target the liver, but its carcinogenic mechanisms are still unknown. Inorganic arsenic induces a spectrum of tumors including hepatocellular carcinoma in mice. Methods: Pregnant C3H mice were supplied with drinking water containing 50 ppm sodium arsenite during their pregnancy. The protein expression profile in the liver of 0.5-day-old. male offsprings exposed transplacentally to sodium arsenite was analyzed using protein 2D gel electrophoresis followed by mass spectrometry (MALDI-TOF). Results: Expression of proteins such as hydroxymethylglutaryl-CoA synthase mitochondrial precursor (HMG-CoA synthase), ${\beta}$-actin (cytoplasmic 1) and apolipoprotein A-IV precursor (Apo-AIV) were induced in mouse liver by sodium arsenite, while uricase (urate oxidase), guanine nucleotidebinding protein beta subunit 2-like 1 (RACK1) and fructose-bisphosphate aldolase B (Aldolase 2) were down-regulated. Summary: Expression of proteins that have been implicated in carcinogenesis, such as HMG-CoA, ${\beta}$-actin, and RACK1, was regulated in the liver of mice transplacentally exposed to inorganic arsenic.

This study was carried out to examine whether kimchi has hypolipidemic effect and to know how it exert lipid-lowering effect in rats. Male Sprague-Dawley rats were fed with kimchi-fee diet, or 3%, or 5%, or 10% kimchi diets for 6 weeks. Plasma cholesterol level was lowered in rats fed all concentrations of kimchi diets, and plasma triglyceride(TG) level was lowered in 10% kimchi diet group compared with that of control significantly(p<0.05). Th intake of kimchi lowered VLDL-cholesterol and VLDL-TG levels, whereas increased HDL-cholesterol level significantly(p<0.05). LDL-cholesterol level was lowered only in 5% kimchi diet group and LDL-TG level was lowered in all kimchi diet groups compared with those of control significantly (p<0.05). the intake of 5% and 10% kimchi diets also lowered the levels of hepatic cholesterol, TG, total lipid, and apolipoprotein B, whereas increased the levels of fecal total fat, cholesterol, TG, and apolipoprotein A-1 significantly(p<0.05). Triiodothyronine(T$_3$) level was elevated in rats fed kimchi diet, whereas thyroxine(T$_4$) level was not affected by kimchi treatment. These observations support that the intake of kimchin in rats loweres plasma and hepatic lipid levels by increasing the excretion of TG and cholesterol through feces, by the elevation of T$_3$ level, and by the altered lipoprotein metabolism.

Since the consumption of spent laying hens as roasted skewered meat increases, the effects of various carotenoids on pigmentation and antioxidant activity were tested with 62-wk-old 250 ISA brown laying hens to improve the quality of chicken meat. In a 6-wk feeding trial, 4 carotenoids with different polarity (${\beta}$-8-apo-carotenoic acid ethyl ester (ACAEE)>astaxanthin>canthaxanthin>${\beta}$-carotene) at 100 mg carotenoid/kg feed were used. The more polar the carotenoids, the higher were the levels in blood. After 5-wk adaptation, the concentrations of astaxanthin, canthaxanthin, and ACAEE in blood were -4 ${\mu}g/ml$. Canthaxanthin decreased significantly (p<0.05) the level of total blood cholesterol. Decreases in blood triglyceride by all carotenoids used were significant. ACAEE and astaxanthin tended to increase skin yellowness of thigh, breast, and wing proportionally to feeding period. In the case of polar carotenoids (ACAEE and astaxanthin), the longer the period of feeding, the higher the accumulation in skin was observed. Only astaxanthin was effective against the production of lipid peroxides in skin. Conclusively, out of the commercially available carotenoids we tested, astaxanthin is recommended for pigmentation of skin and inhibition of lipid oxidation.

This study was designed to investigate the obesity rate with anthropometric indices, nutritional status and serum lipid levels of 260 school children from 5th grade of elementry school residing in Puchon city. Obesity was defined as fat percentage that exceeds 25$\%$. The prevalence rate of obesity were 15.2$\%$ for male and 14.1$\%$ for female. Mean fat percentage, BMI and Rohrer indice of obese male were 30.3$\%$, 21.0 and 150.2 respectively and 28.0$\%$, 21.5 and 151.9 for obese female. Mean serum TG, apo-B of obese female was significantly lower than that of non-obese. Obese male did not show any difference in serum lipid levels. The proportion of students whose serum cholesterol levels exceed 170mg/dI, which is cutoff point of bordeline for coronary artery disease, was 12.0% for male and 15.6$\%$ for female. The major factors affecting nutritional status were the amount of living expense, existence of mother's job and the regularity of having breakfast. Children who's living expense more than 500 thousants Won showed lower intake of Iron, vitamin A, thiamin, niacin and ascorbic acid(p$\ll$0.05). Children who's mothers are having a job were observed with decreased height(p$\ll$0.05). Children having breakfast regularly showed increased BMI and Rohrer indice than those of children having breakfast often of never.

This study was to investigated the effects of the bee venom on inhibition of cell growth via upregulation of death receptor expression in the A549 human lung cancer cells. Bee venom(1-5 ${\mu}g$/ml) inhibited the growth of A549 lung cancer cells by the induction of apoptotic cell death in a dose dependent manner. Consistent with apoptotic cell death, expression of TNFR1, Fas, death receptors(DR) 3, 4 and 6 was increased in the cells. Expression of DR downstream pro-apoptotic proteins including caspase-3, -9 and Bax was concomitantly increased, but the expression of Bcl-2, NF-${\kappa}B$ were inhibited by treatment with bee venom in A549 cells. Moreover, deletion of DR3, DR4 by small interfering RNA significantly reversed bee venom-induced cell growth inhibitory effect, whereas Apo3L strengthened anti-proliferative effect of bee venom through enhancement of DR3 expression. These results suggest that bee venom should exert anti-tumor effect through induction of apoptotic cell death in lung cancer cells via enhancement of death receptor expression, and that bee venom could be a promising agent for preventing and treating lung cancer.
