To investigate the effects of hot water soluble extract from Angelicae Gigantis Radix on lipid metabolism and antioxidant defense system in rats fed hypercholesterol diet, Sprague-Dawley male rats were fed either hypercholesterol diet with water or hot water soluble extract from Angelicae Gigantis Radix. Hypercholesterol diet contained 18 % beeftallow and 5 % cholesterol. After 4 weeks of experimental periods serum and liver obtained. The level of serum lipid and the activities of GOT and GPT was measured. The level of lipid and TBARS and the activity of GSH-Px was measured also. The results obtained were: 1) Food intake in the experimental group supplied hot water soluble extract from Angelicae Gigantis Radix was low significantly. 2) In the experimental group supplied hot water soluble extract from Angelicae Gigantis Radix of serum total lipid and total cholesterol was significantly low. 3) Serum GOT activity was significantly low in the experimental group supplied hotwater soluble extract from Angelicae Gigantis Radix. There was no difference of serum GPT activity between control and experimental group supplied hot water soluble extract from angelical Gigantis Radix. 4) There was no difference of lipid composition, TBARS level and GSH-px activity in liver between control and experimental group. The result of this study indicates that the hot water soluble extract from Angelicae Gigantis Radix was effective in decreasing the food intake of the experimental animals in the hypercholesterol diet and also effective in decreasing the levels of serum total lipid, total cholesterol and GOT activity. However it was not effective to change the level of lipid, TBARS and GSH-Px activity of liver.

The aim of this study is to investigate the effects of hot water soluble extract from Angelicae Radix on the components of serum and liver and the effects on the antioxidant system. For this purpose, five experimental groups were set up. And for fat source, perila oil enough with unsaturated fatty acid and beef tallow enough with saturated fatty acid were supplemented to the rats together with hot water soluble extract from Angelicae Radixs. Five experimental groups kept eight Sprague-Dawley rats respectively. They were CO group supplemented with basic diet of AIN-93, PO group supplemented with perila oil, POA group supplemented with perila oil and hot water soluble extract from Angelicae Radix, BT group supplemented with beef tallow, and BTA group supplemented with beef tallow and hot water soluble extract from Angelicae Radix. The results were; 1) Final weight, weight gain, fluid intake and FER were not different significantly among the experimental groups, 2) Significant difference of food intake was observed(p<0.05) in BTA group only, 3) No significant difference was observed in serum total lipid, serum triglyceride and HDL cholesterol among experimental groups. Serum total cholesterol and LDL cholesterol were significantly low(p<0.05) in the group supplemented with beef tallow which was with hot water soluble extract from Angelicae Radix (BTA group). 4)Liver total cholesterol in liver was low in groups supplemented with perila oil and hot water soluble extract from Angelicae Radix. In summary, hot water soluble extract from Angelicae Radix did not affect the weight gain, fluid intake and food efficiency ratio among the experimental groups, but had an effect of lowering food intake, serum total cholesterol and serum LDL cholesterol significantly in the groups which were supplemented with beef tallow and hot water soluble extract from Angelicae Radix. The effect of lowering liver total cholesterol with the supplementation of hot water soluble extract from AnRelicae Radix was observed in perila oil group only. The effect of lowering cholesterol with the supplementation of hot water soluble extract from Angelicae Radix was observed both in serum and in liver.

This study investigated the synergy effects of hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine on the lipid metabolism and antioxidant defense system of rats on hypercholesterol diets. Sprague-Dawley male rats were fed either a hypercholesterol diet with water or a hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine. The experimental groups consisted of the control group (CO), the group supplied with hot water soluble extract from Eleutherococcus senticosus(ES), and the group supplied with hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine(ESC). Eleutherococcus senticosus was extracted, made into 0.5% solution, and fed to the ES and ESC groups. A 3% carnitine diet was supplied to the ESC group. Hypercholesterol diets contained 18% beef tallow and 5% cholesterol. After 4 weeks of administering these diets, serum and liver were obtained and the level of serum lipid and the activities of GOT and GPT were measured. In addition, the level of liver lipid and TBARS and the activity of GSH-Px were measured. The results were as follows: 1) Weight gain and FER in the group supplied with hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine(ESC) was low significantly(P<0.05). 2) In the groups supplied with hot water soluble extract from Eleutherococcus senticosus(ES) and the group supplied with hot water soluble extract from Eleutherocorcus senticosus and dietarty carnitine(ESC), total serum cholesterol levels were both significantly low (P<0.05,P.0.01). 3) Serum GOT activity was significantly low(P<0.05) in the group supplied with hot water soluble extract from Eleutherococcus senticosus(ES) and in the group supplied with hot water soluble extract from Eleutherococcus senticosus and dietary carnitine(ESC). There was no difference between serum GPT activity in the control group and the groups supplied with hot water soluble extract from Eleutherococcus senticosus or dietary carnitine. 4) Liver triglyceride was low (P.0.05) in the group supplied with hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine(ESC). No difference was observed in other lipid composition, TBARS level, and GSH-px activity in liver between the control group and the experimental groups. In summary, the effects of hot water soluble extract from Eleutherococcus senticosus and dietarty carnitine on the lipid metabolism and antioxidant defense system (such as weight gain, FER, total serum cholesterol and liver triglyceride) were low when Eleutherococcus senticosus and dietarty carnitine were supplied simultaneously.

홍삼의 추출물인 50% ethanol extract, crude saponin, 그리고 lipid soluble fraction이 마우스 대식세포의 oxidative burst를 유발할 수 있는지 여부를 알아보고자 in vitro와 in vivo에 각각의 추출물을 처치하고 hydrogen peroxide 생산을 DCFH-DA를 이용한 형광분광광도법으로 측정하였다. 형광분광법에 의한 hydrogen peroxide의 측정을 최적화하기 위한 DCFH-DA의 농도는 3.2$mu extrm{m}$이었고, oxidative burst를 유도하기 위한 zymosan A, PNA의 최적 농도는 각각 100$\mu\textrm{g}$, 250'기호'를 사용하였다. In vitro의 경우, 홍삼의 3가지 추출물은 모두 oxidative burst를 유발하지 못하였지만, zymosan A로 유발한 경우에는 50% ethanol extract에서 가장 높은 hydrogen peroxide를 생산하였다. In vivo 실험에서는, lipid soluble extract에서만 유의하게 증가한(P<0.01) oxidative burst를 유발하였고, ginsenoside(saponin)가 어느 정도 포함되어 있는 50% ethanol extract와 crude saponin은 대조군에 배하여 유의하게 낮은(P<0.05) hydrogen peroxide를 생산하였다. 이는 ginsenoside가 마우스의 nitric oxide 생산을 억제한다는 다른 연구자들의 보고와 일치하는 결과이다. Oxidative burst를 유발한 lipid soluble extract에는 phenol계 화합물, polyactylence계 화합물, 미량성분 등이 함유되어 있으므로 차후 연구를 통하여 과연 어느 성분이 hydrogen peroxide를 증가시키는지 규명하는 것이 필요하다.

Male Sprageu-Dawely rats fed a cholesterol diet (Control group) or cholesterol diet supplemented with the water-soluble extract of stem bark from Cudrania tricuspidata(CTSB group) at the level of 0.5% for 2 weeks. Concentration of triglyceride in serum of CTSB group was significantly lower than that of control group. However, the other lipids concentrations of liver and serum, body weight gain, and food intake did not show significant difference between CTSB group and control group. Antioxidative activities of water-soluble extract from stem bark of Cudrania tricuspidata on the lipid peroxidation in rat were also studied in vivo by measuring the formation of thiobarbituric acid reactive substance(TBARS). Concentration of TBATS in the liver homogenates of CTSB group was significantly higher than that in control group. Nonheme iron concentration was significantly increased in the liver of CTSB group compared to control group. suggested that enhanced nonheme irom was associated with enhanced peroxidation of liver in CTSB group. These results suggested that water soluble extract from stem bark of Cudrania tricuspidata exert the hypotriglycerolemic effect and might amplify the lipid peroxidation of tissues in cholesterol fed rats.

BACKGROUND/OBJECTIVES: This study was conducted to investigate the effects of fermented soybean (FS) extract on adipocyte differentiation and fat accumulation using cultured 3T3-L1 adipocytes. MATERIALS/METHODS: 3T3-L1 adipocytes were treated with FS and nonfermented soybean (NFS) extract during differentiation for 10 days in vitro. Oil red O staining was performed and glycerol-3-phosphate dehydrogenase (GPDH) activity was measured for analysis of fat accumulation. Expressions of adipogenic genes were measured. RESULTS: Soluble extract of soybean fermented with Aspergillus oryzae GB107 contained higher levels of low-molecular-weight protein than conventional soybean protein did. FS extract ($50{\mu}g/ml$) inhibited adipocyte differentiation and fat accumulation during differentiation of 3T3-L1 preadipocytes for 10 days in vitro. Significantly lower GPDH activity was observed in differentiated adipocytes treated with the FS extract than those treated with NFS extract. Treatment with FS extract resulted in decreased expression levels of leptin, adiponectin, and adipogenin genes, which are associated with adipogenesis. CONCLUSIONS: This report is the first to demonstrate that the water-soluble extract from FS inhibits fat accumulation and lipid storage in 3T3-L1 adipocytes. Thus, the soybean extract fermented with A. oryzae GB107 could be used to control lipid accumulation in adipocytes.

To evaluate the protective effects of extracts of silkworm on carbon tetrachloride-induced hepatotoxicity, serum glutamic-oxaloacetic transaminase, glutamic-pyruvic transaminase and lactic dehydrogenase activities, malondialdehydes values and glutathione-S-transferase activity were measured in ICR mice. Extracts of silkworm was administered orally at 30min after the administration of CCl4 Mice were sacrificed at 24h after the administration of extracts of silkworm. The activities of serum aminotransferase and the hepatic content of lipid peroxide after carbon tetrachloride treatment were markedly increased than normal control but those levels were decreased by the treatment of butanol soluble fraction of silkworm methanol extract. Glutathione S-transferase activity was decreased by carbontetrachloride than control, but also inhibited by the treatment of butanol soluble fraction of silkworm methanol extract.

The concentrations of total polyohenolic compound from extract of Paulownia tomentosa Stued. were water-soluble extract 7.98%, methanol extract 12.30% and ethanol extract 11.63%. The free radical scavenger activities of three extracts at the levels of 0.5% were higher than that of BHT(butylated hydroxytoluene). In antioxidative activities measured the concentrations of TBARS(thiobabituric acid reactive substances) in tissues microsome induced with Fe$\^$++/ascorbate, the water-soluble extract was errdctively suppressed in liver and spleen. In antioxidative activities determined by thiocyanate method against lipid peroxidation using linoleic acid, the methanol extract showed the higher compared with other extracts, but BHT showed the highest antioxidative activity. These results suggest that fruit extracts of Paulownia tomentosa Stued. showed to have relatively high concentrations of polyphenolic compounds and antioxidative activities.
