Renal angiomyolipoma is an uncommon benign tumor of the kidney, with or without tuberous sclerosis, which is composed with mixture of adipose tissue, smooth muscle and blood vessel. Angiomyolipoma without tuberous sclerosis is usually solitary and unilateral, and is predominent in middle aged women. Its clinical and radiologic features are similiar with renal cell carcinoma, so its preoperative daigonosis is difficult, But recently, nephrotomography, ultrasonography and computerized tomography are helpful in diagnostic procedures. Herein we present a case of renal angiomyolipoma without tuberous sclerosis, in 27 years old male.

3성분계 유리 반도체 Ge_(40-x)Sb_xSe_60(x=0, 8, 12, 18, at.%)박막 시료를 thermal evaporation 방법에 의해 제작한 다음 직류 전기 전도도, 광 전기 전도도, 광 흡수도를 측정하였다. X-선 회절 실험에 의해 각 시료는 비정질임이 확인되었다. 직류 전기 전도도는 173K∼423K 온도 범위에서, σ=σ_0 exp(-△Ea/KT)에 따르는 band전도가 지배적이며, 그 값은 1.0×10 exp (-7)∼2.1×10(Ω^-1 ㎝^-1)로 나타난다. Ge_32Sb_8Se_60시료가 가장 높은 직류 전기 전도도를 보인다. 각 시료의 활성화 에너지 △Ea는 0.29∼0.67eV이며, Ge_32Sb_8Se_60시료가 가장 낮은 활성화 에너지를 보인다. 이로서 활성화 에너지가 낮을수록 전도가 잘 일어남을 알 수 있다. 광 전기 전도도는 8.29×10 exp (-4)∼2.76×10 exp (-1)(Ω^-1 ㎝^-1)이며, Ge_32Sb_8Se_60시료가 가장 높은 광 전기 전도도를 보인다. 이로서, Ge_32Sb_8Se_60시료가 가장 많은 D^-결함을 가지는 것으로 추정된다. 광학적 에너지 갭은 0.77eV∼1.13eV이며, 광학적 에너지 갭과 활성화 에너지의 차는, 조성비에 관계 없이 0.45∼0.48eV로서 거의 일정하다. D.C. electrical conductivity, optical absorption, and photoconductivity experiments on glassy semiconductor Ge_(40-x)Sb_xSe_60, for which X concentrations are 0, 8, 12, 18 at% are investigated. By the results of X-ray diffraction experiment, it was convinced that all samples were confirmed as amorphous semiconductor. Over the temperature range from 173K to 423K, the D.C. conductivities of the investigated samples are the form of σ=σ_0 exp(-△Ea/KT) and the values are 1.0×10 exp (-7)(Ω^-1 ㎝^-1)-2.1×10(Ω^-1 ㎝^-1). The sample of Ge-Sb-Se has the highest value in D.C. conductivity. The activation energies of the investigated samples are 0.29-0.67(eV) and the lowest value is appeard in Ge_32 Sb_8 Se_60 firm. The photoconductivities of the samples are 8.29×10 exp (-4)-2.76×10 exp (-1)(Ω^-1 ㎝^-1). The optical energy gaps of the samples are 0.77-1.13(eV). It is shown that the value of difference Eg(the optical energy gap)-Ea(the activation energy) is independent of the compositions.

To assess cardiac structure and function in sustained exercise of two different training modes, 32 subjects were studied. Matched 10 healthy Young men(Control group), 12 isotonic exercise athletes of 12 soccers(Group 1) and 10 isometric exercise weight lifters(Group 2) were evaluated by echocardiography at resting state and at maximal exercise state. The following results were obtained. 1. In isotonic exercise Group 1 of resting state, significantly increased left ventricular mass due to significantly increased diastolic left ventricular dimension and left ventricular dimension and left ventricular end-diastolic volume than controls of resting state. 2. In isometric exericise Group 2 of resting state, significantly increased left ventricular mass was due to not only increased diastolic left ventricular dimension and left ventricular end-diastolic volume but also increased septal wall thickness than controls of resting state. 3. Fractional shortening, ejection fraction, systolic velocity integral and peak acceleration were increased significantly in both isotonic and isometric exercise groups of resting state than controls of resting state. 4. Even though there were no changes in diastolic left ventricular dimenion and left ventricular end diastolic volume between isotonic and isometric exercise groups of resting state, systolic left ventricular dimension and left ventricular end-systolic volume were significantly decreased in isometric exercise group of resting state. Fractional shortening ejection fraction and peak acceleration were significantly increased in isomeric exercise group of resting state than isotonic exercise group of resting state. Moreover, the increment of septal wall thickness was greater in isometric exercise group of resting state than in isotonic exercise group of resting state. 5. In isotonic exercise group of maximal exercise state, left ventricular end-systolic volum and end-diastolic volume were significantly increased than controls of maximal exercise state. There were significant increases of diastolic left ventricular dimension and left ventricular end-diastolic volume in isometric exercise group of maximal exercise state than in controls of maximal exercise state, but there was no change of left ventricular end-systolic volume between those two groups. The left ventricular wall thcikness was mostly increased significantly in isometric exercise, group of maximal state than in controls of maximal exercise state. 6. Fractional shortening and ejection fraction were significantly increased in isometric exercise group of maximal exercise state than controls of maximal exercise state. 7. There were significant decrease of left ventricular dimensions and volumes, and significant increase of fractional shortening, ejection fraction and peak acceleration in isometric exercise group of maxmal exercise state than isotonic exercise group of maximal exercise state. In conclusion, isotonic exercise caused increased left ventricular dimension and increased myocardial contractility, whereas isometric exercise caused increased left ventricular dimension, wall thickening and myocardial contractility. At maximal exercise state, isotonic exercise showed more increased ventricular dimension with increased left ventricular wall thickness and myocardial contractility.

납 폭로 근로자에서 δ-aminolevulinic acid dehydratase 유전형질이 zinc protoporphyrin 및 δ-aminolevulinic acid에 미치는 영향

이병국,황규윤,장봉기,김용배,리갑수,안현철,김화성,이성수,안규동,박종범 순천향대학교 산업의학연구소 1999 순천향산업의학 Vol.5 No.1

The inhibition of δ-aminolevulinic acid dehydratase (ALAD) in the heme synthetic pathway results in increased protophoryphyrin (ZPP) and δ-aminolevulinic acid (ALA) and is responsible for some of toxicological effects of lead. This enzyme is coded by the ALAD gene containing 2 co-dominant alleles. The polymorphisms of ALAD gene may be related to differential effects of lead on ZPP and ALA, ALAD genotype was measured in 975 Korean male lead workers, of whom 897 were homozygous for ALAD1 (ALAD 1-1 genotype) and 96 were heterozygous for ALAD2 (ALAD 1-2 genotype). Blood lead in subjects with ALAD1 was significantly higher than those with ALAD2 (p = 0.01). No difference between ALAD genotypes was found for age, exposure duration, ZPP, ALA, hemoglobin, hematocrit, body mass index, tobacco and alcohol use. After adjustment for possible confounders, ALA and ZPP became significantly elevated in ALAD1 subjects (p = 0.004 and 0.055, respectively). This result suggests that ALAD1 subjects may be more susceptible to the hematotoxicologic effects of lead than ALAD2 subjects.

Objectives: Under the fee-for-service system, Korean hospitals have been suffering from the worsening profitability caused by law medical care fees. To overcome the difficulties, they have maximized the quantity of medical services and made relatively large investment in developing new medical services using high-priced medical equipment, medicines and medical supplies which were not covered by medical insurance system rather than reduced running costs. Materials and Methods: This study was made to analyze and forecast the revenue change of the department of Obstetrics and gynecology of an university hospital in Seoul, expecting the implementation of DRG system in 2000. Results: The results were as follows : 1.During the first two days of hospitalization. 41% of total medical service fee was occurred, which was thought that most of the check-ups and operations were made during this period. After two days of hospitalization, the new occurrence of medical service fee tended to reduce. 2.Out of total medical service fee, 67% of admission fee was occurred after 5 days of hospitalization. This was because medical service fees in obstetrics and gynecology department occurred during the first 5 days of hospitalization. 3.Out of fees for operation, treatment, medical supplies and blood transfusion. 71% was occurred during the first two days. 4. In case of fees for examination, 50% was occurred during the first two days. 5.A total of 53% of fees for medication and injection was occurred during the first 5 days. Conclusions: By the implementation of the DRG system, the income is forecast to increase by 800 won to 310,000 won by the disease group of obstetrics and gynecology department. To increase hospital income with the implementation of DRG system, the results of this study suggest that examinations should be done at out-patient departments before the hospitalization of patient, the discharge of patient should be noticed in advance to reduce the period of hospitalization, and admission appointment system should be implemented for the immediate operation and delivery.
