Hasuohwan(何首烏丸) composed of Polygonum multiflorum Thunb and some medical herbs are known as formula of senescence delay effect. The aim of this study is to investigate the effect of Hasuohwan(何首烏丸) on antioxidant enzyme activity such as Thiobarbituric acid reactive substance(TBARS) in rat plasma and liver, Superoxide dismutase(SOD), Glutathione peroxidase(GSH-px), Catalase(CAT) in rat erythrocyte and liver. Rats were sacrificed and TBARS was measured in rat plasma and liver. SOD, GSH-px and CAT were measured in rat erythrocytes and liver. TBARS in plasma concentrations of HSO group was significantly lower than those of control group. RBC and liver GSH-px activities of HSO group were significantly higher than those of control group. According to above results, it is considered that Hasuohwan is effective in inhibiting lipid peroxidation and increasing antioxidative enzyme activities in D-galactose induced aging rat. Therefore, Hsuohwan is considered in effective of senescence delay.
This study was done to investigate the nutrient intakes and plasma biochemcial indices in 68 female college students according to their skin types. Nutrient intakes were investigated by quick estimation. The plasma TG and total cholesterol levels were measured by the Spotchem sp-4410. The plasma levels of retinol and $\alpha$-tocopherol were measured by HPLC. In addition, the activities of antioxidant defense enzymes such as plasma glutathione peroxidase(GSH-Px) and glutathione reductase(GHS-Rd) were determined. All data were statistically analyzed by SAS PC package program. The results of this study were as follows : The average age, height, weight, BMI, systolic blood pressure and diastolic blood pressure ofthe subjects were $20.9{\pm}1.9yr, 160.7{\pm}4.3cm, 53.0{\pm}7.1kg, 20.5{\pm}2.4kg/m^2, 105.3{\pm}11.5mmHg and 70.6{\pm}7.7mmHg$, respectively. Ten students(14.7%) had normal skin type, 19 students(27.9%) had dry skin type, 11 students(16.2%) had oily skin type, 17 students(25.0%) had acne and 11 students(16.2%) had mixed skin type. The intakes of energy and fats in oily skin group were significantly higher(p<0.05) than those of the dry skin group, but vitamin C intake in the mixed skin group was significantly higher(p<0.05) than those of the dry skin group, but vitamin C intake in the mixed skin group was significantly lower(p<0.05) than that in other skin types. The intakes of other nutrients were not significantly different among skin types. The analysis of lipids showed that the plasma total-cholesterol level of mixed skin group was significantly lower(p<0.05) than that of the oily skin group, whereas other lipid levels were not significantly different. The other parameters such as retinol, $\alpha$-tocopherol, GSH-Px and GSH-Rd of plasma were not significantly different among skin types. Overall results indicate that dietary intake pattern may influence skin type and thereby some blood biochemical indices can be different by skin types.
This present study was designed to evaluate whether supplementaion of dietary coenzyme $Q_{10}$ protects the lipid peroxidation damage in adriamycin (ADR)-treated rats. Two experiments were conducted in this study. Experiment I was undertaken under the condition of simultaneous administration of ADR and coenzyme $Q_{10}$ for 4 weeks. Experiment 2 was undertaken under the same condition as experiment I after feeding the experimetal diets alone without administration of ADR for 4 weeks. Results obtained from the present study were as follows. Lipid peroxide value of plasma and heart mitochondria was elevated by ADR treatment. but decreased according to dietary coenzyme $Q_{10}$ supplementation. Pretreatment with dietary coenzyme $Q_{10}$ was more efficient in reducing ADR-induced lipid peroxide value. The simultaneous use of ADR and coenzyme $Q_{10}$ enhanced the heart glutathione peroxidase (GSH-Px) activity. particularly at higher level of coenzyme $Q_{10.}$ The change of superoxide dismutase(SOD) activity was similar to that of GSH-Px activity. In case of pretreatment with coenzyme $Q_{10, }$ these enzyme activities were more enhanced by dietary coenzyme $Q_{10.}$ However, there was little difference in catalase activity.
This study was conducted to determine effects of spent composts of Se-enriched mushrooms (Se-SMC) as the dietary selenium source on carcass characteristics, plasma glutathione peroxidase(GSH-Px) activity and Se deposition in finishing Hanwoo steers. In combination with both Se-SMC and normal SMC, experimental treatment diets were formulated to contain 0.1, 0.3, 0.6 and 0.9 ppm of Se on a dry matter basis. A total of 20 finishing Hanwoo steers (average BW = 613 kg, average age = 20 to 24 mo) were allotted to treatments in four groups of five steers per pen for 12 wk preceding slaughter. While the experiment is employed, blood samples were taken to analyze Se concentration and GSH-Px activity, and muscle and liver samples were collected for analyses of Se contents in their tissues after slaughter. DMl and BW gain were not affected by dietary Se level and any toxic symptoms in treatments with a higher level of Se were not observed. No differences were noted for carcass characteristics. Se concentration in whole blood and plasma GSH-Px activity were linearly increased with the increasing level of dietary Se (P < 0.01). Se content in the hind leg for Se-SMC supplemented groups significantly increased (P < 0.05) upon dietary Se level, with 0.27, 0.37, 0.40 and 0.46 !1g1g dry, respectively. However, Se content in the loin was not affected by dietary Se levels. Se content in the liver was significantly increased(P < 0.05) as dietary Se increased, with 0.79, 1.40, 2.39 and 3.10 !1g1g dry, respectively. These results suggested that Se in the Se-SMC was highly bioavailable, and Se-SMC might be used not only as an inexpensive way of providing Se for ruminants but also as another way of producing Se-fortified beef.

The protective effect of a mixed powder from solid-cultured and liquid-cultured Lentinus edodes mycelia (2:1, w/w) (designate LED) on the carbon tetrachloride ($CCl_4$)- and ethanol-induced hepatotoxicity of male Sprague-Dawley (SD) rat was investigated. In the $CCl_4$-induced rat hepatotoxicity experiment, rats of 4 groups (6 rats/group) were administere with Normal (0.2 ml distilled water), Control (0.2 ml distilled water), LED (LED 200 mg/kg BW + 0.2 ml distilled water), and Silymarin (200 mg/kg BW + 0.2 ml distilled water), p.o., daily for 2 weeks. Afterwards, all groups except for the Normal group were subjected to abdominal injection with $CCl_4$ ($CCl_4$ : corn oil, 1:1 v/v; 0.5 ml/kg BW). For the ethanol- induced rat hepatotoxicity experiment, rats were divided into 5 groups (5 rats/group): Normal; Pair-fed control (PFC); Control (ethanol); LED (ethanol + LED 200 mg/kg BW); and Silymarin (ethanol + silymarin 200 mg/kg BW). Rats of the Normal and PFC groups were fed a basal liquid diet, and rats of the Control, LED, and Silymarin groups were fed a liquid ethanol diet containing LED or Silymarin. Eight weeks later, blood and liver samples were collected to analyze biomarkers. In $CCl_4$-induced SD rats, LED elevated hepatic superoxide dismutase (SOD), catalase, and glutathione peroxidase (GSH peroxidase) activities and thiobarbituric reactive substances (TBARS) were reduced, resulting in the reduction of glutamate-oxalate transaminase (GOT), glutamate-pyruvate transaminase (GPT) and lactic dehydrogenase (LDH) activities in plasma. Similar results of these enzymes and biochemical markers in both liver tissues and plasma were seen in ethanol-induced hepatotoxicity of SD rats. In addition, elevated alcohol dehydrogenase (ADH) activity and reduced expression of cytochrome p450 mixed monooxygenase enzyme (CYP2E1) were seen in liver tissues from ethanol-treated rats by LED treatment. These effects of LED were similar to those of Silymarin. In in vitro experiments, LED showed antioxidant activity in a 2,2-diphenyl-1-picrylhydrazyl (DPPH) system and mouse liver mitochondria system induced by NADPH/$Fe^{2+}$ and cumine hydroperoxide (CuOOH). These results indicate that LED protected SD rat hepatotoxicity, induced by $CCl_4$ and ethanol, through its antioxidative activity and might be useful as a material for protection from hepatoxicity in humans.
Objective: The objective of this study was to evaluate effects of heat treatment and soybean oil inclusion on protein oxidation of soy protein isolate (SPI) and of oxidized protein on redox status of broilers at an early age. Methods: SPI mixed with soybean oil (SPIO) heated at $100^{\circ}C$ for 8 h was used to evaluate protein oxidation of SPI. A total of two hundred and sixteen 1-day-old Arbor Acres chicks were divided into 3 groups with 6 replicates of 12 birds, receiving basal diet (CON), heat-oxidized SPI diet (HSPI) or mixture of SPI and 2% soybean oil diet (HSPIO) for 21 d, respectively. Results: Increased protein carbonyl, decreased protein sulfhydryl of SPI were observed as heating time increased in all treatments (p<0.05). Addition of 2% soybean oil increased protein carbonyl of SPI at 8 h heating (p<0.05). Dietary HSPI and HSPIO decreased the average daily gain of broilers as compared with the CON (p<0.05). Broilers fed HSPI and HSPIO exhibited decreased glutathione (GSH) in serum, catalase activity and total sulfhydryl in liver and increased malondialdehyde (MDA) and protein carbonyl in serum, advanced oxidation protein products (AOPPs) in liver and protein carbonyl in jejunal mucosa as compared with that of the CON (p<0.05). Additionally, broilers receiving HSPIO showed decreased glutathione peroxidase activity (GSH-Px) in serum, GSH and hydroxyl radical scavenging capacity in liver, GSH-Px activity in duodenal mucosa, GSH-Px activity and superoxide anion radical scavenging capacity in jejunal mucosa and increased AOPPs in serum, MDA and protein carbonyl in liver, MDA and AOPPs in jejunal mucosa (p<0.05). Conclusion: Protein oxidation of SPI can be induced by heat and soybean oil and oxidized protein resulted in redox imbalance in broilers at an early age.

This study was designed to investigate the effects of Hijikia fusiforme (Harvey) Okamura ethanol extract on the ethanol-induced hepatotoxicity of rat administered orally experimental diets for 6 weeks. Sprague-Dawley rats weighing about 100 g were divided into 4 groups; normal group (NOR), ethanol (35% ethanol 10 mL/kg b.w/day) treated group (CON), ethanol and Hijikia fusiforme ethanol extract 200 mg/kg (HE1) and 400 mg/kg (HE2) concomitantly treated group, respectively. Each group was examined for the growth rate, feed efficiency ratio (FER), activities of antioxidative enzymes and contents of TBARS and glutathione. Hijikia fusiforme ethanol extract showed increasing effects of the growth rate by 43%, and FER was gradually increased by Hijikia fusiforme ethanol extract treatment, compard with ethanol treatment. Ethanol elevated the activities of superoxide dismutase, catalase and glutathione peroxidase of rat liver markedly as compared to normal group, but those activities were significantly decreased in Hijikia fusiforme ethanol extract treatment by 56%, 38% and 25%, respectively. Xanthine oxidase activity elevated by ethanol was not affected by Hijikia fusiforme ethanol extract. The content of TBARS increased by ethanol treatment was signigicantly decreased in HE2, and the glutathione content depleted by ethanol treatment was increased by Hijikia fusiforme ethanol extract administration adjacent to normal level. These results suggest that Hijikia fusiforme ethanol extract is believed to be a possible protective effect for the ethanol-induced hepatotoxicity of rat liver.
Increased oxidative stress contributes to the progression of atherosclerosis. We measured serum antioxidant mineral concentrations, capacities of serum antioxidant enzymes and fasting lipid profile in 97 male patients with coronary artery disease (CAD) and 21 male controls. Nutrient intake was assessed by the semi-quantitative food frequency method. CAD patients were divided into single-vessel disease (SVD, n=66) and multi-vessel disease (MVD, n = 31) groups on the coronary angiography. The ratio of serum LDL- to HDL-cholesterol elevated with an increasing number of diseased vessels compared to the control (control < SVD < MVD, p < 0.05). Patients with SVD and MVD had higher levels of serum lipoprotein (a) than the control (p < 0.05). The mean intake of carbohydrate, protein and cholesterol was higher in MVD patients and the intakes of vitamins C and E were lower in MVD and SVD patients than in the control (p < 0.05). Serum copper (Cu) and zinc (Zn) levels were higher in MVD and SVD patients than in the control (Cu: control $75.8{\pm}5.07$, SVD $99.2{\pm}2.90$, MVD $100.1{\pm}2.32{\mu}g/dL$, p<0.01; Zn: $76.8{\pm}5.36$, $119.0{\pm}5.95$, $129.1{\pm}2.70{\mu}g/dL$, p < 0.01). And the ratio of Zn to Cu was higher in SVD and MVD patients than in the control (control $0.78{\pm}0.06$, SVD $0.88{\pm}0.05$, MVD $0.99{\pm}0.04$, P < 0.05). The activity of glutathione peroxidase (GSH-Px) was lower in MVD than in SVD and the control (control $35.13{\pm}1.34$, SVD $35.30{\pm}1.01$, MVD $31.00{\pm}1.04 U/mg$ protein, p < 0.05). The ratio of the activities of superoxide dismutase (SOD) to GSH-Px was higher in MVD than in control and SVD (p < 0.05). In groups with CAD, serum Cu and Zn concentrations and their ratio were changed compared to the control. GSH-Px activity was decreased and the ratio of SOD to GSH-Px was increased in the patients with MVD. The balances between the activities of SOD and GSH-Px should also be considered a risk factor in CAD patients.

This study was designed to investigate the protective effects of Sasa borealis leaves on high glucose-induced oxidative stress in human umbilical vein endothelial cells (HUVECs). Freeze-dried Sasa borealis leaves were extracted with 70% methanol and followed by a sequential fractionation with dicholoromethan, ethyl acetate, butanol and water. The ethyl acetate fraction from Sasa borealis leaves extract (ESLE) was used in this study because it possessed the strongest antioxidant activity among the various solvent fractions. Exposure of HUVECs to 30 mM high glucose for 48 hr resulted in a significant (p<0.05) decrease in cell viability, glutathion (GSH) concentration, activities of antioxidant enzymes including superoxide dimutase (SOD), glutathion peroxidase (GSH-px) and catalase, and a significant (p<0.05) increase in intracellular ROS and lipid peroxidation formation in comparison to the cells treated with 5.5 mM glucose. ESLE treatment decreased intracellular ROS and lipid peroxidation formation and increased cell viability, GSH concentration and expressions of SOD and catalase in HUVECs. These results suggest that ESLE may be able to protect HUVECs from high glucose-induced oxidative stress, partially through the antioxidative defense systems.

This study was done to investigate the effects of Artemisia selengensis methanol extract on ethanol-induced hepatotoxicty in rat liver. Sprague-Dawley(SD) rats weighing about 150g were divided into the following 4 groups : control group(CON), Astemisia selengensis methanol extract administered group(ASE), ethanol adminstered group(ETH) and Artemisia selengenis methanol extract and ethanol administered group(ASA). Ethanol and Artemisia selengenis methanol extract were administered orally by 5m1/kg and 200mg/kg body weight per day for 6weeks, respectively. Body weight, daily food intake and percent liver weight per body weight were significantly changed by ethanol administration in comparison to control group. The activities of serum alanine aminotransferase(ALT), asparate aminotransferase(AST), and hepatic TBA-reactants increased by ethanol were decreased significantly by Artemisia selengensis methanol extract compared with ethanol group. It was also obseued that superoxide dismutase, catalase and glutathione peroxidase were not changed by Artemisia selengensis methanol extract, whereas hepatic xanthine oxidase activity was inhibitied by Artemisia selengensis methanol extract as compared to ethanol group. The glutathione contents in liver decreased by ethanol adminstration, but glutathione levels increased in ASA compared with ethanol group. These results suggest that Artemisia selengenis methanol extract have a possible protective effect on the ethanol-induced hepatotoxicity in rat liver.
