We report a case of acute renal failure with severe loin pain and patchy renal vasoconstriction after exercise. An immediate postcontrast computed tomogram of this case shows multiple patchy areas of poor contrast enhancement in the cortex of the both kidneys. A 24-hours delayed scan without further injection of contrast dye shows multiple wedge-shaped contrast enhancement in the coincident areas of poor enhancement in the immediate scan. The 2 and 5 days delayed scans show that wedge-shaped contrast enhancement becomes disappeared gradually to the renal cortex, and the 8 days delayed scan shows complete disappearance of contrast enhancement. The renal scintigrams with technetium-99m-methylene diphosphonate and dimercaptosuccinic acid show diffuse increased uptakes and multiple patchy photon deficient areas in the both kidneys respectively. The follow-up renal scintigrams show nearly normal findings, This patient had an uneventful hospital course and recovered completely without dialysis.

Leukemia is known to be an extremely rare cause of diabetes insipidus. We report a case of diabetes insipidus as a complication of leukemia. An 18 year-old man was admitted because of polyuria polydipsia and fever. Bone marrow aspiration and biopsy revealed the diagnosis of acute erythroleukemia (AML, M6). On the water deprivation test, the diabetes insipidus was confirmed to be of the central type. He was managed with intranasal vasopressin for diabetes insipidus with good response. Induction chemotherapy was administered without response, and the patient died of septicemia and respiratory failure 2 months after initial diagnosis. A short review of the literature related to this subject is also presented.

The lung is the most common site of metastasis of extrapulmonary malignant tumor. According to past reports, metastatic cancer of the lung has been found in about 2% of all patients at autopsy. But these days, a diagnosis of endobronchial metastatic cancer utilizing bronchoscopy only is not easy. Thus we need other means of gathering more informaction, such as past history, discovery of other metastatic sites, and pathologic findings with special staining and electronmicroscope, especially in cases of poorly differentiated adenocarcinoma and epidermoid cancer, which are common types of primary lung cancer. We present 5 cases of endobronchial metastatic cancer. We found endobronchial metastatic cancer 2 cases of cervix cancer (epidermoid, adenocarcinoma), 1 case of colon cancer (adenocarcinoma), hypernephroma (renal cell carcinoma), and bladder cancer (transitional cell carcinoma). Since it was impossiole to diagnose the metastatic adenocarcinoma from the cervix only with lightmicroscopic findings, we could use past history and unusual radiologic and bronchoscopic findings which was thought to be the specific endoscopic finding of metastic endobronchial cancer. The interval between the diagnosis of the primary cancer and endobronchial metastatic cancer was 25.7 months. In the future, development of immunohistochemistry, monoclonal antibody, and molecular biologic techniques will give us diagnostic clue for differential diagnosis of metastatic endobronchial cancer from primary bronchogenic lung cancer.

사료내 아미노산비가 흰쥐의 성장 , 도체성분 , 조직 유리아미노산 농도 및 뇨내 질소배설량에 미치는 영향

신종서,라창식,김창혁,김병완,송영한 한국영양사료학회 1999 韓國營養飼料學會誌 Vol.23 No.4

본 논문에서는 아미노산 혼합사료를 이용하여 사료내 질소 수준을 1.6N%로 일정하게 조절한 후 ET%의 단계적 변화(30, 50, 70ET%)가 휜쥐의 성장, 체성분, 혈중요소태 질소, 조직내 유리아미노산 농도 및 뇨중 질소량 변화에 미치는 영향을 검토하였다. 그 결과는 다음과 같이 요약되었다. 1. 증체량은 30ET%구에서 유의적으로 낮게(P<0.05) 나타났으나 사료섭취량은 50ET%구에서 유의적으로 높게 나타났으며(P<0.05), 증체량과 사료섭취량간에는 높은 상관이 인정되었다. 2. 도체 및 간장의 성분은 사료내 ET%의 변화에 의한 영향이 없는 것으로 나타났다. 3. 혈중 유리아미노산의 농도는 사료내 ET%의 변화에 민감하게 반응하였으며 특히 threonine 농도는 30ET%구에 비하여 70ET%구가 약 35배 정도로 유의적으로 높게 나타났다(P<0.05). 또한 총 필수아미노산의 농도는 사료내 ET%의 증가에 따라 유의적으로 증가하였으나 비필수아미노산 농도는 유의적으로 감소하였다(P<0.05). 간장 및 근육내 총필수아미노산과 비필수아미노산의 농도도 혈중 아미노산의 농도 변화와 비슷한 경향을 보였다. 4. 사료내 ET%에 따른 질소 배설량은 저 ET%구에 비하여 고 ET%구에서 높게 나타났으며 사육초기 보다 사육후기에 높은 질소 배설량을 보였다. 이와 같은 결과로 미루어 사료내 아미노산 조성은 중체량과 사료섭취량에 영향을 미칠 뿐만 아니라 조직내 아미노산 농도 및 질소 배설량에도 영향을 주기 때문에 정제 아미노산을 사료에 첨가할 때에는 비필수아미노산의 함량도 고려함으로서 효율적으로 사료의 이용성을 중진시키는 방향을 모색하는 것이 바람직 할 것으로 사료된다. The objective of this study was to investigate the effect of ET(essential amino acid/total amino acid) ratio variations (30, 50, 70 ET%) in the feeds on growth, body composition, blood urinary nitrogen, concentration of free amino acids in tissues and urinary nitrogen of rats. The nitrogen level in feed was constantly maintained at 1.6% with a purified amino acid, despite the difference in ET ratios. The results obtained are summarized as follows; 1. Body weight gain and feed intake was significantly lower and higher in 30 and 50 ET% than in other groups, respectively(P<0.05), and body weight gain was highly correlated with feed intake. 2. No ET% ratio effects on composition of carcass and liver were observed. 3. The concentration of plasma free amino acids varied with ET% ratios in the feeds, especially the concentration of threonine in 70 ET% was 35 times higher than that in 30 ET%. The concentration of total essential amino acids was significantly elevated by increasing ET% ratios in the feeds. In liver and muscle, the patterns of total essential amino acids and nonessential amino acids were similar to that of plasma amino acids. 4. Urinary nitrogen concentration increased with higher ratios of ET% in the feeds, and was higher in early growth stage than in late growth stage. These results indicate that the amino acid composition in the feeds influence the concentration of amino acids in tissue and urinary nitrogen as well as body weight and feed intake.

Jehovah's Witness patients who require an operation represent a challenge to the physician because of the patients' refusal to accept a blood transfusion. We report 5 years experience with a consecutive series of 12 Jehovah's Witness patients in the Obstetric & Gynecological department who underwent operation. In 12 cases, death ensued in one patient who underwent subtotal hysterectomy for ectopic pregnancy. The cause of death was severe anemia & complicated respiratory problems. We discussed the problem of elective & emergency operations on Jehovah's Witness patients. Anesthesiologists must understand legal aspects, as well as and ethical, if they are to conduct their practice as an art as well as science.

Shock absorber has a great influence on the performance of the vehicle(ride comfort, manipulation, noise, vibration, turning, stability). Therefore, in this study we consider theoretically about general damper, variable damping oil damper, the control of vehicle Characteristics for the suspension, and undesirable phenomenon. And we measured the vibration/noise characteristics of shack absorber for the real car experimentation, strain change, and noise characteristics of shock absorber using experimental equipment. The study of domestic company and research institute on the vehicle shock absorber is active, but that of basis is not. So we think that they should be accomplished actively. Therefore, this paper will develop theoretical system on the vibration/noise characteristics of shock absorber by theoretical consideration and experimental result analysis of dynamic characteristics of shock absorber that were accomplished in this study. Then we will use it as the optimistic design data for shock absorber development.

박영철,박경숙,김순점,길찬일,신정순,채병국 대한마취과학회 1982 Korean Journal of Anesthesiology Vol.15 No.3

It is a well known fact that the major craniofacial operation is a complicated procedure. In this procedure, the operative period is extremely long and blood loss is large, extremely difficult to estimate and continuous into the early postoperative period. The air way should be protected intraoperatively and postoperatively due to frequent airway obstruction. We had experienced of an anesthetic management for correction of hypertelorism. Anesthetic management of this case should focus on reduction intracranial pressure and volume. We had performed neurolept anesthesia with controlled hyperventilation. The careful monitoring and frequent measuring of blood gas analysis, hematocrit, hourly urine output, electrolytes, body temperature, CVP, ECG, and acid-base balance status are recommend. We report a case of anesthetic management for a patient.

TiO₂ films deposited on glass were prepared by plasma sputtering method. The dependence of structural properties on the deposition conditions and the photocatalytic degradation of methylene blue were investigated. When the oxygen partial pressure was higher than 5%, as-deposited TiO₂ films exhibited an almost amorphous structure under DC plasma condition. A transition at which metallic mode deposition(Ti) changed to dielectric mode deposition(TiO₂), was observed at the 5∼10% oxygen partial pressure under RF plasma condition. The amorphous structure changed to anatase structure by heat treatment at 400℃ for 4 hours. Crystallized anatase structure had a preferred orientation along 〔101〕 direction. For 150 min of photocatalytic degradation, the concentration of methylene blue was reduced by half.
