현재까지도 완전히 규명되지 못한 간질환과 혈청 구리 및 아연농도와의 관련성을 밝히고, 이들의 진단적 가치를 알아보고자 1990년 10월에서 1991년 8월 사이에 대구시 소재 모 대학병원 내과와 건강진단센터에 내원한 사람들 중에서 무작위로 선정한 정상 63명, 간경변 60명 그리고 간암 33명을 대상으로 일반적 특성을 조사하였고, 체내 일일 변동을 고려하여 공복시 오전 9시에서 11시 사이에 혈액을 채취하여 간기능검사의 생화학적 표지자와 혈청 구리 및 아연농도의 분석에 사용하였다. 혈청 구리의 평균농도는 대조군 $91.97{\pm}4.76{\mu}g/dl$, 간경화군 $106.21{\pm}2.73{\mu}g/dl$ 그리고 간암군 $127.05{\pm}0.77{\mu}g/dl$이었고, 대조군과 간경화군 사이에 통계적으로 유의한 차이는 없었으나, 간경화군과 간암군사이에는 통계적으로 유의한 차이를 보였다(p<0.05). 아연에 있어서는 대조군 $110.82{\pm}7.24{\mu}g/dl$,간경화군 $68.10{\pm}5.43{\mu}g/dl$ 그리고 간암군 $63.78{\pm}2.20{\mu}g/dl$로 나타났고, 간경화군과 간암군 사이에 통계적으로 유의한 차이는 없었으나, 대조군과는 두 군 모두 통계적으로 유의한 차이를 보였다(P<0.05). Cu/Zn비는 세 군 사이에 모두 통계적으로 유의한 차이가 있었다(p<0.05). 간기능검사의 생화학적 표지자들 중에 총 단백, 알부민, ALP 그리고 총 빌리루빈은 세 군 간에 모두 통계적으로 유의한 차이가 있었으나(p<0.05), ALT와 AST의 간경화군과 간암군 간의 차이는 통계적으로 유의하지 않았고, 직접 빌리루빈은 대조군에 대해 간암군에서 통계적으로 유의한 차이가 없었다. 헐청 구리와 아연농도 그리고 Cu/Zn비와 통계적으로 유의한 상관관계를 보인 표지자는 세 군에서 다양하게 나타났다. 다중 로지스틱 회귀분석에서 간경화 및 간암에 대한 odds ratio는 혈청 아연농도만이 각각 0.951, 0.952로 통계적으로 유의하였고(p<0.05), 혈 청 구리 농도와 Cu/Zn비는 통계적인 유의성이 없었다. 세 군에 대한 판별분석에서 구분을 위한 주요변수로 선정된 것은 알부민, ALP, 혈청 아연농도, 나이 그리고 총 빌리루빈이었고, 이를 적용하여 판별한 결과 바른구분의 백분율은 대조군 95.4%, 간경변군 73.4%, 간암군 75.7%로 총 84.0% 였다. 본 연구는 아연이 간질환에 대해 독립적으로도 억제하는 효과가 있을 것이며, 혈청 아연농도의 측정은 간질환의 진단에 유용하게 이용될 수 있을 것임을 시사하고 있다고 생각된다.

Twenty-eight Brangus cattle were used to determine the effect of copper and selenium supplementation on performance, feed efficiency, composition of fatty acids in Longissimus dorsi (LD) muscle, and cholesterol concentration in serum and in LD muscle and enzymes activities, reduced glutathione (GSH) and oxidized glutathione (GSSG). The treatments were: i) Control, without copper (Cu) and selenium (Se) supplementation; ii) Se, 2 mg Se/kg of dry matter such as sodium selenite; iii) Cu, 40 mg Cu/kg of dry matter such as copper sulfate; iv) Se/Cu, 2 mg Se/kg of dry matter such as sodium selenite and 40 mg Cu/kg of dry matter such as copper sulfate. LD muscle fatty acid composition was not influenced by the treatments (p>0.05). The serum concentration of cholesterol was not influenced by the treatments (p>0.05), however, the concentration of cholesterol in LD was lower in cattle supplemented with copper and selenium (p<0.05). Oxidized glutathione and reduced glutathione increased (p<0.05) with Cu, Se and Se/Cu supplementation. The supplementation of copper (40 mg/kg DM) and selenium (2 mg/kg DM) altered the metabolism of lipids in confined Brangus cattle, through a decrease in cholesterol deposition in the LD, possibly by changing the ratio between reduced glutathione/oxidized glutathione. Copper and selenium supplementation improved animal performance and feed efficiency (p<0.05) when compared to the control group, providing advantages in the production system, while also benefiting consumers by reducing cholesterol concentration in the meat.

An experiment was conducted to determine the effect of dietary copper (Cu) on performance, carcass characteristics and lipid metabolism in lambs. Fifty DorperMongolia wether lambs (approximately 3 month of age; 23.80.6 kg of body weight) were housed in individual pens and were assigned randomly to one of five treatments. Treatments consisted of 1) control (no supplemental Cu), 2) 10 mg Cu/kg DM from Cu-lysine, 3) 20 mg Cu/kg DM from Cu-lysine, 4) 10 mg Cu/kg DM from tribasic copper chloride (Cu2(OH)3Cl; TBCC), 5) 20 mg Cu/kg DM from tribasic copper chloride. The Cu concentration was 6.74 mg/kg DM in the basal diet. Body weight was measured on two consecutive days at the start and the end of the 60-day experimental period. Blood samples were collected and then the lambs were slaughtered on d 60. Performance was not affected (p>0.05) by dietary Cu treatment. Cu-supplemented and control lambs had similar hot carcass weight, dressing percentage and longissimus muscle area, but Cu supplementation, regardless of source and level, reduced (p<0.01) 12th rib backfat and kidney fat in lambs. Plasma tumor necrosis factor-alpha (TNF-) and serum triglyceride concentrations were increased (p<0.05), total cholesterol concentrations were decreased (p<0.05) and nonesterified fatty acids (NEFA) concentrations tended to be increased (p<0.07) by Cu supplementation. However, Serum concentrations of HDL-cholesterol and LDL-cholesterol were not affected (p>0.05) by dietary treatment. Fatty acid profile of longissimus muscle was similar across treatments. These results indicate that Cu-lysine and TBCC are of similar availability in lambs. Cu supplementation given to DorperMongolia wether lambs altered lipid metabolism. The reduction in backfat depth may be due to copper altering TNF- metabolism in lambs. Supplementation of 10 or 20 mg Cu/kg DM showed similar effects on lipid metabolism in lambs.

In this study, we investigated the effects of ostrich extract combined with Korean herb medicine(OEKHM) on the serum parameters in carageenan induced paw edema in rats. Carageenan causes enhanced edema formation which contributes to the pathophysiology of inflammation. Male Sprague-Dawley rats were used. There were four groups of treatments: OEKHMs and the control. After treatment with oral doses of 3 mL/180 g BW. 3 kinds of OEKHMs were processed which were ostrich bone with flesh meat with herb medicine(BFH), ostrich bone with flesh meat(BF), and ostrich bone with internal organs(BI). The contents of crude fat of the BFH was lower, but crude protein and crude ash of the BFH were significantly higher than those of the BF and the BI. In case of the levels of minerals(Ca, P, Mg, Fe, Cu and Zn ) of the BFH were significantly higher than those of BF and BI. And the heavy metals(Pb and Cd) were not detected in the OEKHM. The serum level of triglyceride in the BFH treated group decreased compared to that of the edema induced group. The serum levels of HDL-cholesterol concentration in the BFH supplemented group increased compared to that of the other groups. The serum levels of minerals(Ca, Mg, Fe, Cu and Zn) of the BFH treated group significantly increased than those of other groups(p<0.05).

This study has examined the effects of Aralia elata Seemann ethanol extract on antioxidant enzyme systems inrats along with benzo($\alpha$) pyrene(B(a)P) administration . The ethanol extract of Aralia elata Seemann (50mg/kg body wt.) was fed to rats for 4 weeks by stomach tubing. The extract administration increased antioxidant activities of glutathione sulfur transferase(GST) comparing to the control. also total superoxide dismutase(SOD) and Cu, Zn-SOD activities were stimulated. Catalase activities were increased by 50% with the extract feeding compared to the control . Combined administration of B($\alpha$)P and the extract increased GST activity in B($\alpha$) P group. Although total SOD acitivity was decreased , Cu, Zn-SOD was greately increased from 0.10unit to 0.18 unit and catalase activity also was increased compared to the group of B($\alpha$) P. GST activity in CLE group was 1.32 unit, increased by 33% comparing to the group CL of 0.99unit. Cu, Zn-SOD and catalase activities in thegroup fed high fat and ethanol extracts were increased by 25% and 39%, respectivley comparing to the group of high fat. In addition , total SOD was decreased but, Cu, Zn-SOD acitivity was increased from 0.09 unit to 0.18unit. Catalase activity was 76.05 unit in the group of B($\alpha$) P and extract comparing to 65.26 units in B($\alpha$)P group. Serum $\alpha$-tocopherol of rat was markedly increased by theextract. Administration of B9$\alpha$)P reduced $\alpha$-tocopherol levels in the serum, on the other hand, lard in the diet increased $\alpha$-tocopherol levels in the serum. The above results indicate that Aralia bud exerts antioxidant functions in vivo against B($\alpha$)P. Further research may be necessary for the identification fo the biologically active material.

This study was undertaken to investigate the effect on the Cd accumulation in long-term Cd poisoned rats. 40 male weaning Sprague Dawley rats weighting 80-90g were divided into 4 groups (LCuLFeCd : low Cu, Fe and Cd group, ACuLFeCd : adequate Cu, low Fe and Cd group, ACuAFeCd : adequate Cu, adequate Fe and Cd group) according to Cu and Fe levels (Cu 0.5ppm, 8.5ppm : Fe 6ppm, 40ppm) for 12 weeks. There were no significant difference in water intake, feed intake, and body weight gain according to dietary Cu and Fe consumption. But the mean food intake and body weight gain of adequate Fe groups(LCuAFeCd, ACuAFeCd) were higher than those of deficient Fe groups (ACuLFeCd, LCuFeCd)in long-term Cd poisoned rats. The mean Cd levels of serum, liver, kidney, and urine in ACuAFeCd group were lower than those of Cu and /or Fe deficient groups. But the mean fecal Cd excretion of ACuAFeCd group was higher than that of Cu and/or Fe deficient groups. And the mean Cd retention amount of ACuAFeCd group was lower than those of Cu and/or Fe deficinet groups. In conclusion, these results provide an evidence that adequate Cu and Fe intakes can decrease Cd accumulation in rats. Therefore, in the point of increasing environmental Cd contamination, adequate Cu and Fe intakes must be suggested to prevent Cd accumulations.

최근 건강에 대한 관심이 증가하고 유리기 산소에 의한 산화 및 염증이 다양한 질환과 관련이 있다는 사실이 밝혀지면서 식품류는 의약품에 비해 장기간 섭취하여도 안전하고 친숙하게 접할 수 있는 장점 때문에 천연물이나 각종 식품류에서 항산화 및 항염증과 관련된 새로운 물질을 탐색하는 연구가 활발하게 진행중에 있다. 그 가운데 4배성 휘커스 오디품종 '대성뽕' [Morus Lhos(Ser.) Koids]의 주색소는 anthocyanins이며, cyanidin-3-glucoside형태로 0.794% DW가 함유되어 있어서, 다른 오디품종에 비해 많은 양이므로 항산화 활성도 비례하여 클 것으로 판단된다. 따라서 본 연구에서는 오디추출물의 중년 남, 녀의 혈청 무기질과 항산화 관련 물질에 대한 개선에 대한 효과를 알아보고자 4주간 오디추출물을 급여(100 mL/day)하여 섭취 전 후의 혈청 무기질 및 혈중 항산화 관련물질을 분석하여 비교하였다. 1차적으로는 오디추출물을 제조하여 무기질 함량과 항산화능을 측정한 결과 무기질 함량은 칼슘(80.66 mg), 마그네슘(12.26 mg), 철분(6.26 mg), 구리(0.05 mg), 아연(4.01 mg) 함량으로 나타나 칼슘, 철분, 아연 함량이 높게 나타났다. DPPH소거능에 따른 오디추출물의 항산화능을 보면 비타민 C를 기준(100%)으로 했을때 cyanidin-3-glucoside는 85%,오디추출물은 34%로 cyanidin 3-glucoside의 약 40%의 소거능력을 보였다. 2차적으로는 이러한 오디추출물 섭취 전과 후 대상자들의 혈청 중 무기질 수준을 조사해 보았을때 여자 대상자의 경우 혈청 철분, 구리 및 아연 함량이 유의적으로 증가되었고, 남자 대상자의 경우는 철분 함량만이 유의적인 증가를 보였다. 혈청 지질산화와 관련 있는 혈청의 TBARS와 FRAP수준의 변화를 조사한결과 오디추출물 급여 후 남자, 여자 대상자의 혈청 FRAP수준이 유의적으로 증가되었고, 평균 혈청 TBARS 수준은 남, 녀 모두 감소되는 경향은 보였다. 결과적으로 오디는 항산화성이 뛰어나고 무기질을 공급할 수 있는 새로운 과일로 가치가 있다고 판단된다.

Two feeding trials were conducted to study the effects of different chelated copper and zinc compounds on the performance and fecal excretions of weanling pigs. In Exp. 1, 150 weanling pigs ($L{\times}Y{\times}D$, $12.30{\pm}2.07kg$) were randomly assigned to five dietary treatments: 170 ppm Cu from $CuSO_4$, 85 ppm Cu from Cu amino-chelate (CAC), 170 ppm Cu from CAC, 85 ppm Cu from Cu-Lysine (CL), and 170 ppm Cu from CL. In Exp. 2, 150 weanling pigs ($L{\times}Y{\times}D$, $12.52{\pm}1.80kg$) were randomly assigned to five dietary treatments: 120 ppm Zn from $ZnSO_4$, 60 ppm Zn from Zn-amino-chelate (ZAC), 120 ppm Zn from ZAC, 60 ppm Zn from Zn-Methionine (ZM), and 120 ppm Zn from ZM. In both experiments, pigs were randomly distributed to the treatments following a randomized complete block design on the basis of body weight as the blocking variable. Each experiment was conducted for 28 days. Blood and fecal samples were collected to determine mineral contents as affected by the dietary treatments. There was no difference (p>0.05) in ADG and ADFI among treatments, but F/G was improved (p<0.05) in pigs fed diet with 170 ppm CAC than 85 ppm CL but not different (p>0.05) to the control (170 ppm $CuSO_4$). Regardless of copper source, concentration of Cu in serum and feces were higher in pigs fed diet with 170 ppm Cu than pigs fed diet with 85 ppm Cu (Exp 1). In Exp 2 the ADG was higher (p<0.05) in pigs fed diet with 120 ppm ZM than in pigs fed diets with 120 ppm $ZnSO_4$ and 60 ppm ZAC and ZM. The serum zinc concentration was generally higher (p<0.05) in pigs fed diet with organic source than the control group ($ZnSO_4$). Also, there was a trend towards a decrease in fecal excretions of zinc when dietary zinc level was low. The efficacy of the two chelated copper and zinc sources is similar in terms of growth performance. The fecal excretions for Cu and Zn could be reduced in pigs fed low level of these minerals using organic sources.

The superoxide dismutase (SOD) mimetic activity of copper complex of 3,5-disopropylsalicylic acid (Cu(II)-DIPS) was tested and compared to those of human recombinant SOD (hrSOD) and its conjugate form with polyethyleneglycol (PEG) using fer- ricytochrome c reduction assay. Stability constant of Cu(II)-DIPS was measured po- tentiometrically using SCOGS2 program. In the presence of 10 g/L albumin, Cu(II)-DIPS lost most of its SOD mimetic activity. HrSOD was modified with polyethylene glycol (PEG) of M.W. 5000. These conjugates have markedly prolonged plasma half-lives of enzymatic activity (15.5 hr) compared to native hrSOD (5 min). In summary, efficient SOD mimetics should be stable enough not to dissociate in blood by serum protein. HrSOD could have longer half-life by conjugation with inert PEG for sustained SOD effect.
