  • This study was carried out to investigate the effect of Meristotheca papulosa on lipid concentration of serum and liver in rats fed high fat diet for 4 weeks. Experimental groups ere divided into normal group (5% corn oil), high fat diet group (5% corn oil+20% lard), high fat diet and 5% or 10% Meristotheca papulosa treated group. The weights of kidney, heart and tests were not significantly different among the group, but weight of liver was significantly decreased by supplement of Meristotheca papulosa (10%). The contents of serum total lipid, trigly-ceride, total cholesterol, free cholesterol, cholesterol ester and atherogenic index were decreased, while HDL-cholesterol was increased by Meristotheca papulosa supplementation compared to high fat diet group. Meristotheca papulosa supplement has obvious effects on lowering hepatic total lipid, triglyceride and total cholesterol. Our findings suggest that Meristotheca papulosa supplement can improve lipid metabolism in high fat fed rats.

  • Nickel toxicity and interactions of nickel with zinc, copper, and lead were studied in glowing chicks fed supplemented diet. Feed intake and growth rate of the chick were reduced by 250mg nickel as a sulfate salt per kg of feed. The toxicity of nickel was decreased by zinc or copper supplementation, but not lead. High nickel feed increased nickel level in kidney and decreased zinc levels in tibia and plasma. However, low zinc levels in tibia and in plasma were reversed by zinc supplementation. Hemoglobin, packed cell volume, and aortic elastin content were increased in chicks fed nickel. These results suggest that nickel toxicity is induced by interference with zinc metabolism.

  • The effect of Artemisia princeps var orientalis(mugwort) and Circium japonicum var ussuriense (Unggungqui) on lipid metabolism was examined . Thirty rats of 5 experimental groups were fed with a diet containing 1% cholesterol and 0.25% sodium cholate(control diet) and 5% plant powder or its water soluble extract(experimental diet) for 4 weeks. The activity of enzymes related to liver function, lipid components of liver and principle organs, and fecal steroids were assayed. The activity of enzymes was significantly lower in the unggungqui and mugwort powder diet group than in control. Liver total cholesterol , free cholesterol, and triglyceride levels were significantly lower in Unggungqui powder diet groups that in the control. The concentrations of total cholesterol , triglyceride and phospholipid in heart and kidney were comparatively low in the Unggungqui powder diet groups. In each plant powder diet group, the values of serum bile acid were significantly lowe ran the fecal steroid excretion was higher than in the control and the extract diet groups.

  • Fumonisins are a family of mycotoxins produced from Fusarium verticillioides. Most of fumonisin B1 (FB1) toxicities can be explained by its ability to alter sphingolipid metabolism by inhibiting ceramide synthase. At least, the elevation in dihydrosphingosine (DHS) mediates the earliest toxicity of FB1. Some tissues such as kidney and liver, may be most affected by FB1 because they shows high rates of de novo sphingolipid synthesis. Recent review on FB1 toxicity by A.H. Merrill Jr. et al. suggested the possible role of dihydrosphingosine 1-phosphate (dihydroS1P), which sometimes elevated in cell- or tissue specific manners. (omitted)

  • Patients with inborn metabolic disorder (IMD) show multisystemic manifestations. Heterogenous renal manifestations can develop in IMD patients as well. In this review, the major renal manifestations of IMD and their representative IMDs are described. The major renal manifestations include Fanconi syndrome, renal tubular acidosis, nephrolithiasis, renal cysts and glomerulopathy, and diverse types of IMDs such as carbohydrate metabolism disorders, lysosomal disorders, organic acidemias, mitochondrial disorders, purine and pyrimidine disorders present renal manifestations. Therefore, general and regular renal function evaluation is recommended in addition to specific investigation according to IMD phenotypes.

  • The purpose of this study was to define the content of requisite human structure and function knowledge needed for clinical knowledge of nursing practice. Subjects of human structure and function were divided into 10 units, and each unit was further divided into 21 subunits, resulting in a total of 90 items. Contents of knowledge of human structure and function were constructed from syllabus of basic nursing subjects in 4 college of nursing, and textbooks published by nurse scholars prepared with basic nursing sciences. The degree of need of 90 items was measured with a 4 point scale. The subjects of this study were college graduated 136 nurses from seven university hospitals in Seoul and three university hospitals located in Chonnam Province, Kyungbook Province, and Inchon. They have been working at internal medicine ward, surgical ward, intensive care unit, obstetrics and gynecology ward, pediatrics ward, opthalmology ward, ear, nose, and throat ward, emergency room, rehabilitation ward, cancer ward, hospice ward, and their working period was mostly under 5 years. The results were as follows: 1. The highest scored items of human structure and function knowledge necessary for nursing practice were electrolyte balance, blood clotting mechanism and anticoagulation mechanism, hematopoietic function, body fluid balance, function of plasma, and anatomical terminology in the order of importance. The lowest scored items of human structure and function knowledge necessary for nursing practice was sexual factors of genetic mutation. 2. The highest order of need according to unit was membrane transport in the living unit, anatomical terminology in movement and exercise unit, mechanism of hormone function in regulation and integration unit, component and function of blood in oxygenation function unit, structure and function of digestive system in digestive and energy metabolism unit, temperature regulation in temperature regulation unit electrolyte balance in body fluid and electrolyte unit, concept of immunity in body resistance unit, and genetics terminology in genetics unit.

  • Tissue homogenates of Ehrlich ascites tumor tissues and several normal tissue of mice were incubated separately in medium maintaining $C^{14}$_acetate concentrations of 5, 10, 20, 30, 40, 50 and 60 mg%, in order to determine maximum oxidative rates of acetate. In every incubation experiments, respiratory $CO_2$ samples rapped by alkaline which was placed in the center well of the incubation blask were analyzed for total $CO_2$ Production rates and their radoactivies. The fractions of $CO_2$ from medium acetate to total $CO_2$ production rate were obtained with relative specific activities (RSA) which were calculated by ratio between specific activities (SA) of $CO_2$ and medium $CO^{14}$_acetate and $CO_2$ production rates from medium acetate were calculated from RSA and total $CO_2$ production rates. Maximum plateau values of oxidative rates described above were determined at incubation experiments of various concentrations of medium acetate and compared the oxidative rates of acetate of tumor with those of normal tissues such as kidney, brain and liver. Maximum plateau values of total $CO_{2}$ Production rates were obtained at acetate concentration of 20 mg% and represent $25.0{\pm}0.54\;{\mu}M/hr/gm$ in the brain, $16.3{\pm}2.5$ in the kidney, $9.1{\pm}1.78$ in the liver and $11.5{\pm}3.2\;{\mu}M/hr/gm$ in the ascites tuners. Substancial $CO_2$ yield was observed in the tumor tissues as in the normal tissues. On the other hand, plateau values of RSA were $25.7{\pm}1.04%$ in thee brain, $9.1{\pm}0.72%$ in the kidney, $2.5{\pm}0.73%$ in the liver and $0.51{\pm}0.12%$ in the tumor tissues. $CO_2$ yields from the medium acetate, were 4.19 in the kidney, 2.28 in the brain, 0.228 in the liter and $0.059\;{\mu}M/hr/gm$ in the tumor tissue. These show wide range even in the normal tissue but remarkable decrease in the tumor tissue. This fact means that further oxidation of acetate was inhibited remarkably in the tumor tissue.

  • 생쥐에 1 Gray(Gy)와 3 Gy의 방사선을 조사한 후 시간에 따라 골격근, 심장, 신장, 간 및 정소조직의 형태적 변화를 확인하였다. H-B(hematoxylin-eosin)염색 결과 apoptotic body는 다른 조직에 비해 간조직에서 쉽게 관찰되었고, 조사량에 비례하였으며 대부분의 조직에서 조사 후 1일에, 정소조직에서는 7일에 많이 관찰되었다. TUNEL (terminal deoxyribonucleotidyl transferase-mediated dUTP-digoxigenin nick end labeling)염색에 의한 결과도 동일하게 나타났다. 방사선 조사 후 단백질량은 신장을 제외한 나머지 조직에서 감소되었으며, 3 Gy를 조사한 경우 1 Gy보다 모든 조직에서 초기 2시간까지 감소되었으나 7일에는 모두 증가되었다. 젖산탈수소효소(EC 1.1.1.27, Lactate dehydrogenase: LDH) 활성은 모든 조직에서 증가되었고 1 Gy를 조사한 경우 초기에 더욱 증가되었으며 최고 활성은 3 Gy보다 빠른 시기에 나타났다. 골격근, 심장, 신장 및 정소조직은 일반적으로 $A_4$동위효소 활성이 감소되고 골격근과 심장은 $B_4$$A_2$$B_2$동위효소 활성이 증가되었으며 신장은 이질사량체의 활성이 증가되었다. 간은 $A_4$ 동위효소 활성이 높았고 정소는 C동위효소의 활성이 높았다. 따라서 LDH는 방사선 조사시 간조직을 제외한 나머지 조직에서 lactate oxidase로서 작용하여 호기적 대사가 우세한 것으로 사료된다.

  • 본 연구에서는 선행연구에서 우량 콩나물로 선별된 이소 플라본을 다량 함유한 콩나물의 투여가 실험적으로 유발된 고지혈증 흰쥐의 지질대사에 미치는 효과를 조사하였다. 고지혈증은 SD계 흰쥐에 cholesterol 0.5%, lard 9.3%, sodium cholate 0.2%를 함유한 AIN standard식이에 의해 유발되었다. 실험군은 정상 대조군, 고지혈증 대조군, 고지혈증 유발식이에 1%, 5% 콩나물 분말, 또는 0.2% 대두 이소플라본 추출물 보충군으로 하였다. 실험식을 4주간 투여한 후 혈장 지질과 과산화물 수준, 간조직의 항산화효소 활성도, 혈장 항산화 영양소 수준을 측정하여 다음과 같은 결과를 얻었다. 콩나물 분말의 보충 투여는 고지혈증 동물의 식이효율$(0.33{\sim}0.34)$에 영향을 미치지 않았으며 고지혈증 쥐에서 혈장 중성지질의 저하 경향을 보였으며 총 콜레스테롤 농도의 유의적인 저하효과를 나타내었다. 또한 콩나물 분말 투여는 고지혈증 동물들에서 투여량에 관계없이 혈장과 간, 신장, 심장 등 조직 중의 지질과산화물 수준을 낮추는 경향을 보였으나 그 저하효과는 대두 이소플라본 추출물의 효과보다는 낮았다. Catalase와 glutathione peroxidase 등 항산화효소들의 활성도는 고이소플라본콩나물의 투여로 대조군에 비해 유의적이지는 않았지만 증가되는 경향을 나타냈으며 혈장의 vitamin A수준은 5% 콩나물 투여군에서 유의적으로 높았고 vitamin E 수준은 유의적인 차이가 없었다. 이상의 결과로부터 이소플라본이 풍부한 콩나물의 투여는 고지혈증 동물에서 혈중지질 개선효과가 대두 이소플라본 추출물의 효과와 유사하거나 더 높은 것으로 나타났으며, 유의적이지는 않았으나 조직중 지질과산화물생성을 억제하고 항산화영양소 수준을 높이는 경향을 나타내었다. 이와 같은 결과는 본 실험에서 사용한 콩나물 시료가 높은 이소플라본 함량 이외에도 식이섬유를 다량 함유하고 있으므로 섬유에 의한 부가적인 효과에 의한 것으로 추정되며 콩나물의 영양적 우수성을 일부 입증한 결과로 평가된다.
