본 실험은 육용계 기초사료에 copper와 Vit. E＋Se을 첨가급여시 육계의 혈청 IgG수준과 증체량 및 질병 발생율과의 상관관계를 조사함으로써 가금의 영양과 면역반응에 관한 기초적인 정보를 얻고자 실시하였다. 닭의 혈청중 IgG함량을 처리별, 시기별로 RID test에 의해 측정한 후 이를 증체량 및 건강상태와 비교한 결과는 다음과 같다. 1. 대조구의 혈청중 IgG함량은 부화 직후에 최고치 (4.26mg/$m\ell$)를 나타내었으며 2주령까지 급격히 감소하여 최소치 (0.87mg/$m\ell$)를 유지하다가 그후에 점차적으로 증가하여, 7주령에는 2.48mg/$m\ell$의 수준을 보였다. 2. 혈청 IgG의 농도와 증체량과의 상관성은 사육전기에는 고도의 유의적인 부의 상관관계를 보였으며 3주령에서 가장 높은 상관계수(r＝-0.423)를 나타냈으며 사육후기에는 정의 상관관계를 나타내어 7주령시의 IgG농도와 3주령시 증체량간에는 r＝＋0.246의 상관계수를 보였다. (p＜0.01) 3. Cul5, Cu25와 ES2O군의 혈청 IgG수준은 2주령에서 대조군에 비하여 낮은 수준을 보이다가 3주령에는 급속히 상승한 반면에 대조군에서는 이와 같은 현상이 1주일 늦게 나타났다. 이는 Cu나 Vit. E와 Se을 혼합 첨가 급여할 경우에는 능동면역의 발달이 대조군보다 1주일 조기에 일어나는 것으로 판단된다. 4. Cu15와 Cu25의 증체량은 대조군보다 높은 수준을 나타내었다. 특히 4주령시 증체율은 대조군에 비하여 4.8%와 4.5%높았다. ES2O군의 증체효과는 없었으며 ES 40군은 대조군보다 유의적으로 낮은 증체유을 보였다. 5. Cul5, Cu25, ES2O, ES4O군은 대조군에 비하여 높은 건강 수준을 유지하였으며 폐사율은 각각 1.9%, 1.9%, 2.9%와 1.0%로써 대조군의 4.8%에 비하여 낮은 수준을 보여 질병에 대한 저항능력이 향상되었다.

The purpose of this study was to evaluate the relation of nutrients intake and copper status between nonvegetarian female college students and lacto-ovo-vegetarian female college students. The height, weight and serum copper concentrations were determined. Food nutrients analysis procedure was made by computer using food composition table. The results was summarized as followed; 1) Mean values of weight & height were respectively 53.581$\pm$1.68kg.157.051$\pm$1.43cm in nonvegetarians and 51.23$\pm$1.45kg.156.65$\pm$1.24cm in facto-ovo-vegetarians. 2) The average intakes of protein, fat, carbohydrate, fiber, Ca, P, Fe and Vit. C were above the RDA in the two groups, but those of calories was below the RDA in non-vegetarians. Especially, fiber and icon intakes were significant in the two groups(p< 0.01, p< 0.05). 3) The percentage of iron absorption was 7.64% in nonvegetarians and 5% in facto-ovo-vegetarians. 4) Mean serum copper values of nonvegetarian and vegetarian were 107.08$\pm$14.39ug/100m1 and 113.31$\pm$20.86ug/100ml, respectively.

This study was done to compare serum levels of lipids, trace minerals, ceruloplasmin and ferroxidase activity between female college smokers and nonsmokers. Serum levels of lipids, Cu, Zn, ceruloplasmin and ferroxidase activity were determined in 33 smokers and 42 nonsmokers residing in the Seoul area. Serum levels of TG, total cholesterol and HDl-cholesterol were measured using test kits. Serum Cu Zn were determined by the AAS. Serum ceruloplasimin level and ferroxidase activity were determined by spectrophotometric methods. All data were statistically analyzed by the SAS PC package program. Mean and standard errors were calculated for each item, and the significance of the difference between two groups was evaluated by Student's t-test at p〈0.05. There was no significant difference in levels of total cholesterol, TG, VLDL-cholesterol, LDL-cholesterol, LDL/HDL and atherogenic index, but HDL-cholesterol level was significantly lower(p$\ll$0.05) in female college smokers than in nonsmokers. Serum zinc level showed no significant difference, whereas copper level was significantly higher in smokers, consequently yielding higher Cu/Zn ratio in smoking college women. Ceruloplasmin level was 32.6mg/dl in smoking college women, which was significantly higher(p$\ll$0.05) than that of 28.6mg/dl in nonsmokers. However, cerulopasmin ferroxidase activity, 0.34U/mg in nonsmokers was higher(p$\ll$0.05) than that of 0.29U/mg in smokers. From these results, it is confirmed that cigarette smoking itself has a very detrimental effect on health and mineral nutritional status although the smoking history is relatively short among college women(pack-years=1.7).

Research was conducted to determine the micromineral status of grazing cattle in three climatic regions of the province of South Sulawesi, Indonesia. Soil, forage, blood and liver samples were collected within the Western, Central and Eastern regions in February-March and August-September of 1987. Forages were deficient in copper, selenium and zinc. Serum copper was deficient in all regions but zinc was deficient more in the dry season. Liver copper was deficient in all regions and both seasons except in the central region in the rainy season. Based on the analyses, microminerals most likely deficient in both the rainy and dry seasons for each region were as follows: Western-copper, selenium and zinc; Central-manganese and copper; Eastern-selenium, copper and zinc. Some degree of molybdenum excess was found in the Eastern region.

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.

This study was performed to assess the effect of one year's of meal service for home-staying urban elderly with low incole on their nutritional status. One hundred and eighty three subjects, who had already completed the first nutritional survey, were assigned to two group : meal served(served) and non-meal served(non-served). A meal containing approximately on half of the RDA for energy, protein, calcium and iron was served as lunch everyday to served group. After on year of meal service, follow-up-nutritional survey was done and changes of parameters were analyzed with paired t-test. Served female showed signficantly increased intake of riboflavin and calcium, while non-served female showed significantly decreased intake of calcium. Serum total protein, serum albumin and serum cholesterol were significantly increased in female regardless of meal service. Served remale was observed with significantly elevated LDL-cholesterol, whereas non-served female showed singnificantly lowered HDL-cholesterol. Significantly decreased serum iron, serum transferrin saturaion and significantly increased TIBC were observed for female regardless of meal service. But the proportion of anemic elderly according to Hb or serum iron was decreased more in served group. Female showed significantly increased serum zinc and copper regardless of meal service, whereas only served male showed significantly increased serum copper.

The purpose of this study was to compare the mineral status of postmenopausal vegetarian women with those of the omnivores, and to investigate the relationship between dietary pattern and minerals status in postmenopausal Korean women. The research group was composed of vegetarian women (n = 38), all of them were seven day adventists, who had been on vegetarian diet over 20 yrs. Their anthropometric measurements, dietary intakes, and blood mineral concentrations were compared to age matched omnivores controls (n = 38). The average age of vegetarians and omnivores were 60.7 yrs and 60.5 yrs, respectively and there was no significant difference. The mean daily energy intake of vegetarians and omnivores were 1518.5 kcal and 1355.5 kcal, respectively and their was no significant difference. The mean calcium intake of vegetarians (492.6 mg) was not significantly different from that of omnivores (436.6 mg). The vegetarians consumed significantly greater quantities of magnesium (p < 0.001), iron (p < 0.001), copper (p < 0.001), manganese (p < 0.001) and dietary fiber (p < 0.05). There were no significantly differences in serum calcium, magnesium and manganese levels between vegetarians and omnivores. However, serum levels of phosphorus (p < 0.01), iron (p < 0.05), ferritin (p < 0.01), zinc (p < 0.001) and copper (p < 0.05) were significantly lower than those of omnivores. In conclusion, vegetarian postmenopausal women may have low bioavailability of iron, zinc and copper. Therefore it was needed that further study on mineral bioavailability of vegetarian diet.

The present study was carried out to investigate the serum minerals profile in buffaloes (Bubalus bubalis) suffering from parturient haemoglobinuria (PHU) along with minerals profile of soils and fodders from the disease prone areas and their interrelationships. Serum samples were collected from 60 each of healthy and PHU affected buffaloes randomly selected from field cases. Serum samples were collected from each animal. Fifty composite soil samples were collected where PHU was prevalent. Fifty samples of fodders including leaves and stems being fed to the diseased buffaloes were collected. The difference in the levels of calcium and potassium between upper and lower soil surface of disease prone areas under study were statistically non-significant. The mean values of phosphorous, copper, iron, selenium and molybdenum in upper soil surface were significantly (p<0.05) higher than in lower soil surface. None of the fodders offered to the diseased animals met the dietary requirements of phosphorus and copper whereas none of the fodders was deficient in potassium, iron and selenium rather were having excess of potassium, iron and selenium. The concentration of calcium was adequate in lucerne, berseem, sarson and sorghum, while maize, sugarcane and wheat straw did not meet the required levels for dairy animals. Molybdenum contents in all fodders were adequate to meet the dietary requirements of the dairy buffaloes. Serum phosphorus, copper and selenium were significantly (p<0.001) lower whereas potassium, iron and molybdenum in buffaloes suffering from PHU were significantly (p<0.001) higher than in healthy buffaloes. It was concluded that phosphorous deficient soils play a major role by transferring this deficiency to plants and ultimately reaching to animals where hypophosphataemia is a consistent finding.

Methylglyoxal (MG) is an endogenous physiological metabolite which is present in increased concentrations in diabetics. MG reacts with the amino acids of proteins to form advanced glycation end products. In this in vitro study, we investigated the effect of MG on the structure and function of ceruloplasmin (CP) a serum oxidase carrier of copper ions in the human. When CP was incubated with MG, the protein showed increased electrophoretic mobility which represented the aggregates at a high concentration of MG (100 mM). MG-mediated CP aggregation led to the loss of enzymatic activity and the release of copper ions from the protein. Radical scavengers and copper ion chelators significantly prevented CP aggregation. CP is an important protein that circulates in plasma as a major copper transport protein. It is suggested that oxidative damage of CP by MG may induce perturbations of the copper transport system and subsequently lead to harmful intracellular condition. The proposed mechanism, in part, may provide an explanation for the deterioration of organs in the diabetic patient.

Copper sulfate is widely used as a fungicide and pesticide. Acute copper sulfate poisoning is rare but potentially lethal in severe cases. Copper sulfate can lead to cellular damage of red blood cells, hepatocytes, and myocytes. Toxic effects include intravascular hemolysis, acute tubular necrosis and, rhabdomyolysis. A 76-year-old man presented with vomiting and epigastric pain. He had ingested a copper-containing fungicide (about 13.5 g of copper sulfate) while attempting suicide 2 hours prior to presentation. From day 3 at the hospital, laboratory findings suggesting intravascular hemolysis were noted with increased serum creatinine level. He was treated with a chelating agent, dimercaptosuccinic acid (succimer). His anemia and acute kidney injury gradually resolved with a 19-day regimen of succimer. Our case suggests that succimer can be used for copper sulfate poisoning when other chelating agents are not available.
