심히 진행된 위암 환자에서 경정맥 포도당 투여시의 insulin 및 성장 호르몬 반응을 관찰하고 경구 투여시와 비교 검토하였다. 다시 위암 환자에게 아미노산 용액을 투여하고 혈중 insulin 농도와 성장 호르몬 농도 및 혈당량을 경시적으로 측정하고 정상인에서의 결과와 비교하여 다음의 결과를 얻었다. 1) 위암 환자에게 포도당 용액을 경구 부하하면 혈중 포도당 농도의 상승은 감소되었다. 2) 위암 환자에게 포도당 용액을 경구투여하였더니 insulin 반응은 정상인에서보다 감소되어 경정맥투여시와 유사하였다. 3) 위암 환자에게 포도당 용액 또는 아미노산용액을 경정맥 투여하여 성장 호르몬 농도의 상승을 관찰하였다. 4) 위암 환자에게 아미노산 용액을 정맥내로 투여하면 정상인에서와 같이 경구투여시에 비하여 insulin 반응의 감소가 관찰되었다. 5) 위암 환자에게 포도당 경정맥 투여시의 insulin 반응이 경구 투여시와 유사한 점에 대하여 고찰하였으며 아미노산 경정맥 투여시에는 insulin 반응에 유의할 필요성을 지적하였다. Glucose tolerance, insulin and growth hormone responses following glucose for amino acids administration by means of parenteral or oral load were studied in patients with far advanced gastric cancer. Hormone responses following nutrients load showed in patients with gastric cancer were compared to those of healthy subjects. Results were as follows: 1) Blood sugar appearance following oral glucose administration was diminished in patients with far advanced gastric cancer. 2) The insulin responses of gastric cancer following oral glucose were also diminished as compared to that of normal subjects and were identical with parenteral route. 3) Parenteral administration of glucose or amino acids to patients with gastric cancer resulted in a increase of plasma growth hormone level. 4) Lower insulin response to amino acids was observed on parenteral administration in patient with gastric cancer as in healthy subjects. 5) Author discussed that the low insulin response after oral glucose administration showed in gastric cancer, and any additional insulin requirement arise when longer periods of parenteral amino acid administration are necessary, as in the patient with malnutritions. $quot;

This study aims to investigate the effect of carbon content on the surface nitrogen permeation of 13%Cr-1.8%Al alloyed stainless steels. The surface nitrogen permeation was performed at 1050℃-1200℃ in the 1㎏/㎠ nitrogen gas atmosphere. The nitrogen permeated surface layer of the specimen containing 0.03%C consists of AlN, martensite and retained austenite phases, while the surface layer of the specimen containing 0.14%C appears the AlFe₃C_x phase including former three phases. The specimen containing 0.14%C shows lower total case depth than that containing 0.03%C at the nitrogen permeation temperatures of 1050℃ and 1100℃, while the total case depth of the specimen containing 0.14%C is remarkably increased at the temperature of 1150℃ and 1200℃ due to the increase in the retained austenite content. Martensitic phase, AlN and AlFe₃C_x precipitate of the nitrogen permeated surface layer cause to increase the surface hardness of 550∼600Hv.

육성돈 단백질 사료로서 원산지가 다른 대두박 및 이들 원료에 어분을 3%씩 대체하여 배합한 한국산 대두박(KSBM), 중국산 대두박(CSBM), 인도산 대두박(ISBM), 한국산 대두박 + 어분(KSF), 중국산 대두박 + 어분(CSF) 및 인도간 대두박 + 어분(ISF)의 6처리구를 공시하여 생체내 아미노산 이용율을 루명하고자 (T-cannula가 장착된 6두의 돼지를 6 × 6 Latin 방각법으로 배치한 후) 대사 시험을 실시하였으며, 결과를 요약하면 다음과 같다. 1. 외관상 Fecal 아미노산 소화율은 모든 처리구 중에서 ISBM구가 다소 높았고 CSBM구가 낮았으나 거의 비슷한 경향이였으며, 대두박의 일정량을 어분으로 대체하므로서 다른 어분 대체구보다 중국산 대두박에 어분을 대체한 CSF구의 소화율이 상당히 증진되었다. 각 처리구의 필수아미노산중에서는 arginine, histidine 및 methionine의 소화율이 높았고 비필수아미노산 중에서는 glutamic acid의 소화율이 높았다. 2. 외관상 ileum 아미노산 소화율은 모든 처리구 중에서 KSBM구가 86.6%로서 가장 높았고 CSBM구가 80.1%로 낮았으나 대두박의 일정량을 어분으로 대체하므로서 다른 어분 대체구보다 중국산 대두박에 어분을 첨가한 CSF구의 소화율이 증진되었다. 각 처리구의 필수아미노산 중에서는 arginine, histidine 및 methionine의 소화율이 높았고 비필수아미노산 중에서는 glutamic acid의 소화율이 높았다. 3. Fecal 아미노산 소화율에서 ileum 아미노산 소화율을 뺀 차이로서 가장 큰 차이는 CSBM 및 KSF구에서 나타났으며, 각 처리구의 필수아미노산 중에서 가장 큰 차이는 KSBM, ISBM, KSF 및 CSF구에서는 threonine이였고, CSBM구에서는 valine이며, ISF구에서는 phenylalanine이였다. 비필수아미노산 중에서 가장 큰 차이는 KSBM, CSF 및 ISF구에서는 glycine이였고, CSBM, ISBM 및 KSF구에서는 proline이였다. This studies were performed to compare the effects of various prorein sources such as Korean soybean meal (KSBM), Chinese soybean meal (CSBM) and Indian soybean meal (ISBM), and Korean soybean meal + Fish meal (KSF), Chinese soybean meal + Fish meal (CSF) and Indian soybean meal + Fish meal (ISF) replaced 5 percent of their soybean meals by 3 percent of fish meal on the amino acid digestibility of growing pigs. Six pigs fitted with a simple T-cannula were assigned in 6 × 6 Latin Square Disign for digestion trial. The results obtained were as followed. 1. Apparent fecal amino acid digestibility of the ISBM was a little higher than any other treatments, and digestibility of the CSBM was the lowest of all the treatments, and the digestibility of the CSF treatments which replaced a fixed quantity of the CSBM by fish meal was grown much more than the others. The digestibility of Arginine, Histidine, and Methionine were higher on the essential amino acids of each treatments, and the digestibility of glutamic acid was higher on the non-essential amino acids. 2. Apparent Ileum amino acid digestibility of KSBM(86.6%) was the highest of all the treatments, but that of CSBM(80.1%) was the lowest, As replacing CSBM by a fish meal, the digestibility of CSF was improved. The digestibilities of Arginine, Histidine, and Methionine were higher on the essential amino acids, and the digestibility of Glutamic acid was higher on the non-essential amino acids. 3. When fecal amino acid digestibility was subtracted by Ileum amino acid digestibility, the highest difference appeared at CSBM and KSF. The highest difference on the essential amino acid of each treatment was that Threonine is KSBM, ISBM, KSF and CSF, Valine is CSBM, phenylalanine is ISF. The highest difference on the non-essential amino acid was that Glycine is KSBM, CSF and ISF, proline is CSBM, ISBM and KSF.

It was known that the color of Hematite(Fe₂O₃) is red, while Magnetite(Fe₃O₄) is dark blue. To clarify the origin of red color on the steel plate, the relationship between the volume fraction of oxide phases and the color of steel plate was investigated in this study. The volume fraction of Wu¨stite, Magnetite, and Hematite was quantitatively evaluated by a direct comparison X-ray method using crystal structure informations. Furthermore, the effect of volume fraction and the manufacturing process on the surface color of steel plate was investigated. It was found that FRT(final rolling temperature) played an important role on the plate color.

An imaginative innovation to shorten hospital stays as a means to reduce patient charges, is out-patient surgery. This procedure also minimized the inconvenience and disruption of the family unit, reduced the opportunities for cross-infection, and freed hospifal beds for the more serriously ill patienta Since the concept of out-patient surgical service was organized, managed, and performed in the Hanyang Medieal Center, we had experience of 132 ambulatory anesthetics during the last two years (from Jan. 1974. to Dec. 1975 ). The results are summarized as follower 1. Preanesthetic examination should be routinely cheeked with Hb., Hct., urinalysis and chest x-ray. 2. Premedication should be administered preanesthetically, atropine sulfate intravenously. 3. ASA class 1 patients should be rhnsen fnr short (less than 1 hour) procedures. 4. Anesthesia is induced with Epontol+S.C.C. and maintained with Halothane+N2O+O2. 5. We suggest that ambulatory anesthesia should be more carefully planned, organized, and managed.
