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.

A new type of Si diaphragm was fabricated using Si-wafer direct bonding and two-step electrochemical etch-stopping methods. Using the new diaphragm structure in mechanical sensors, more precise control of cavity depth and diaphragm thickness was achievable. Also, the propagation of the stress, which was generated near the bonding interface, to the surface can be avoided. Finally, a piezoresistive-type Si pressure sensor was fabricated utilizing the diaphragm and a digital pressure gauge, which can display units of pressure, was realized.

본 시험은 여러 가지 광물질과 혼합된 크롬 피콜린 산을 첨가한 사료의 급여가 비육돈의 성장, 도체특성, 혈액성상에 미치는 영향을 알아보기 위하여 수행되었다. 개시체중이 69㎏인 총 513두의 비육돈을 돈방당 16∼21두씩 수용하여 사양시험을 수행하였으며, 9마리가 대사시험에 사용되었다. 처리구는 2개의 단백질 수준별 대조구 (Con 12, Cen 14)와 외산 크롬 피콜린산 (CrP-CaCO₃ ; Prince사 제품). 크롬 제오라이트 (CrP-Zeolite 12, 14), 국산 크롬 피콜린산 1 (CrP-CaCO₃; KIST 개발), 크롬 피콜린산-산화아연 (CrP-CaCO₃-ZnO 12, 14) 그리고 국산 크롬 피콜린산 2 (CrP-CaCO₃ ; M. H. Lee 개발)이었다. 성장성적에 있어서는 일당중체량, 일당사료섭취량, 사료효율 등 모든 조사항목에서 처리구간의 차이가 발견되지 않았으나, 등지방 두께는 크롬 피콜린산 첨가에 의해 감소하는 경향이 발견되었고, 이러한 경향은 출하체중이 무거울수륵 뚜렷하게 나타났다. 도체등급은 크롬 제오라이트구와 크롬 피콜린산-산화아연처리구에서 높게 나타났으며, 혈액내 콜레스테를의 함량도 크롬 제오라이트구와 크롬 피콜린산-산화아연처리구에서 대조구에 비해 유의적으로 감소하였다 (p<0.05). 크롬 피콜린산-산화아연처리구와 크롬 피콜린산구에서 건물 및 단백질 소화율이 향상되었다 (p<0.05). This experiment was conducted to investigate the effects of chromium picolinate in different combinations with minerals on growth, carcass characteristics, serum traits and nutrient digestibility in finishing pigs. Five-hundred and thirteen pigs (69.0 ㎏ of initial weight) were assigned to 9 treatments, each containing three replicates of sixteen to twenty-one pigs each. Additional nine pigs were used in a digestion trial. Treatments were two controls (12% CP and 14% CP), foreign CrP-CaCO₃, two CrP-Zeolite (12% CP and 14% CP), domestic CrP-CaCO₃ 1, CrP-CaCO₃-ZnO (12% CP and 14% CP) and domestic CrP-CaCO₃ 2. ADG was not significantly different among the treatments. Tenth rib backfat thickness tended to be decreased by feeding diet with CrP. Carcass grade was improved by using zeolite and CaCO₃ + ZnO along with CrP in diets. Serum cholesterol level was significantly reduced by feeding diets containing CrP with CaCO₃ + ZnO or Zeolite compared with the control. Supplementation of Cr with CrP-CaCO₃ + ZnO or CrP-CaCO₃ in diets significantly improved the digestibility of crude protein and dry matter (p<0.05). The excretion of nitrogen was lower in pigs fed diets containing Cr regardless of the combinations with minerals. The excretion of phosphorus was lowest in the CrP-CaCO₃ + ZnO group which showed the highest phosphorus digestibility.

Midazolam maleate, a water soluble banzodiazepine unlike diazepam, was synthetized by Walser and Fryer in 1975. In order to ealuate the effectiveness as an induction agent for general anesthesia, 22 elective surgical patients belonging to ASA classification 1 and 2 were selected. And ten patients (male 7, female 3, average 33.5 years old) were induced with midazolam maleate 0.2mg/kg and twelve patients (mdale 7, female 5, average 32.5 years old) with diazepam 0.3mg/kg. The results were summarized as follows. 1) Anesthesia was induced in all of midazolam group by one intravenous injection, but only 6 patients of diazepam group could induced by one injection and the other 6 patients needed 2 or more injections. 2) The changes of blood pressure and pulse rate after induction and intubation were almost similar in the two groups, but greater individual variation was seen in diazepam group. 3) A buring sensation following intravenous injection was noted in 11 cases of diazepam group, but none in midazolam group and no phlebitis in either group. From the above results, diazepam and midazolam are almost similar in nature but midazolam is definitely effective as an induction agent and has less side effects. Therefore midazolam maleate is regarded as a more effective agent than diazepam as an induction for general anesthesia.

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.

In this study, the radiation monitoring system using CsI(TI) scintillation counter is developed for the measurement of radiation distribution in the field of high dose level. When the inner diameter of collimator is 8 mm, we have realized the optimum detecting efficiency and spatial resolution. At that time, the position resolution was 10 cm at 1 m from the system. And experimental results indicated that the energy resolution of the system were 10 % for 662 keV of Cs-137, 7.6 % for 1.17 MeV of Co-60, and 5.8 % for 1.33 MeV of Co-60. Also, we have shown that the real radiation distribution images may be obtained by our measurement system.

To understand systematically the hematological changes including the bone marrow changes in chemotherapeutic agent-induced bone marrow hypoplasia and to define the relationship between hematological and bone marrow scan findings and prognosis of the hypoplasia, CCNU (lomustine) was given orally to 44 rabbits to induce hypoplasia of the bone marrow. And serial changes of peripheral blood and bone marrow findings and (111)In Cl(3)((111)In scan)/(99m)Tc tin colloid bone marrow scan((99m)Tc scan) were checked before and after induction of hypoplasia. With assessment of 28 evaluable rabbits, the following results were obtained: 1) Significant hypoplasia of the bone marrow developed around day 4 of CCNU administration and recovered around day 14(cellularity 51,4±13.5% and 24. 5±14.97o before and after CCNU respectively, p<005). Megakaryocyte count was significantly depressed from 95.67,26% to 36.7$gt;31.82%(P$lt;0.005). M: E ratio was decreased from 162±1.19 to 0, 0.5$lt;0. 43(p±0.005). Shift to left(475), maturation a(40%), naked nucleus and degenerated cells(20%), increase of lymphocytes(47%), monocytes and reticulum cells were also found. 2) The uptake ratio of the 99(m)Tc tin colloid bone marrow scan was markedly increased in contrast to the depression of the bone marrow(4.4±2.12 and 14.1±7.06 before and 4 days after CCNU, respectively, p40. 005). Tc scan uptake ratio was inversely related to the cellularity(r=-0.442, p$lt;0.05) and megakaryocyte number of the bone marrow(r= 0.89, p< 0.01) and peripheral blood granulocyte (r = 0. 54. Pg0.01) and platelet count(r=0.40, p$lt;0.05). There was not significant correlation between (111)In scan uptake ratio and hematologic parameters. 3) The amplitude of the change of the (99m)Tc scan uptake ratio was significantly related to the prognosis of the rabbits with experimentally induced hypoplasia of the bone marrow(dead 5.1±2,67, survivors 2,5±0.96, P<0.01). The change of the (111)In scan uptake ratio was not related to the prognosis of these rabbits. In experimentally induced rrow hypoplasia, morphologic changes in addition to the numerical changes of the bone marrow elements were observed. And serial (99)Tc scan of the bone marrow appears to be helpful assessing the severity and predicting the outcome of bone marrow hypoplasia.
