김태환,정인용,김성호,김경중,방효창,류성렬,진수일 대한방사선 방어학회 1990 방사선방어학회지 Vol.15 No.2

원자력산업의 시설증대로 우라늄 오염의 가능성이 증가되고 있음에도 불구하고 종사자 및 국민에대한 안전대책 및 의료적 처치에 관한 연구가 매우 미흡한 실정에 있어 이에 대한 응급처치방안을 수립코자 우라늄을 투여한 후 제염제를 투여하여 관찰하였던 바 다음과 같은 결론을 얻었다. 1. 우라늄오염에 의한 체중변화에 미치는 제염제의 영향에 있어서 sodium bicarbonate와 생리적 식염수를 병행투여한 군과 우라늄을 투여하고 30분이 지나서 dithiothreitol을 투여한 군에서는 우라늄단독투여군에 비해 체중이 현저하게 증가하였다. (P<0.05). 2. 모든 실험군은 우라늄오염에 의한 음수량과 배뇨량의 변화를 유의성 있게 호전시켰으며(P<0.05), 특히 sodium bicarbonate와 생리적 식염수를 병행투여한 군과 우라늄을 투여하고 30분이 지나서 dithiothreitol을 투여한 군이 가장 높은 증가경향을 나타냈다(P<0.05). 3. 우라늄오염에 의한 BUN농도 변화에 미치는 제염제의 효과는 sodium bicarbonate와 생리적 식염수를 병행투여한 군과 우라늄을 투여하고 30분이 지나서 dithiothreitol를 투여한 군이 공히 우라늄단독투여군보다 BUN농도가 매우 감소되었다(P<0.01). 4. 우라늄을 투여하고 30분이 지나서 dithiothreitol를 투여한 군은 우라늄오염에 의한 serum creatinine의 농도증가를 유의하게 감소시켰으나 (P<0.01), sodium bicarbonate와 생리적 식염수를 병행투여한 군은 다소 감소하는 경향으로 나타났다. 5. 우라늄오염에 의한 urine creatinine농도 변화에 미치는 제염제의 효과에 있어서 sodium bicarbonate와 생리적 식염수를 병행토여한 군과 우라늄을 투여하고 30분이 지나서 dithiothreitol를 투여한 군에서는 우라늄단독투여군에 비해 creatinine의 배설이 상당히 증가하였다(P<0.05). 6. 우라늄오염에 의한 신장의 소견에 있어 우라늄단독투여군은 근위곡세뇨관상피의 공포화 및 종창, microvilli와 brush border의 손실, 세뇨관 상피의 괴사가 관찰되었으며, 간장의 충혈, 중심성 괴사 우라늄을 투여하고 30분이 지나서 dithiothreitol를 투여한 군에서는 우라늄단독투여군에 비해 높은 방호효과가 관찰되었으나 다른 실험군에서는 큰 효과가 없는 것으로 나타났다. 결론적으로 우라늄의 체내오염시에는 sodium bicarbonate와 생리적 식염수를 가능한 빨리 병행투여하거나 dithiothreitol을 체내오염후 30분이 지나서 투여하는 방법이 우라늄오염에 대한 제염에 매우 유효할 것으로 생각되며, 특히 우라늄에 의한 인체장해를 유의하게 경감시켜줄 것으로 사료되었다. Appreciable radiation exposures certainly were occurred m the reactor burn-up, the nuelear fall-out and the surroundings of nuclear installations with radioactive effluents. Therefore ,radioactive nuclides is not only potentially hazardous to workers of nuclear power plants and related industrials, but also the wokers who handle radioactive nuclides in biochemical research and nuclear medicine diagnostics. And in the case of occurring the nuclear accidents, the early medical treatment of radiation injury should be necessary but little is established'medical procedures to decontaminate the victims of internal contamination of radioactive nuclides in korea. Accordingly, to achieve the basic data for protective roles and medical treatment of radiation injury, the present studies were can-id out to evaluate the decontamination of uranium by the chemical drugs. The results observed were summarized as follows : 1. The combined treatmet group of sodium bicarbonate and saline with uranyl nitrate injection simultaneously and the dithiothreitol group that was administered 30 minutes after uranyl nitrate injection were increased significantly in the change of body weight than uranyl nitrate-only group(P<0.005). 2. All the experimental groups were increased the fluid intake and urine volume on the uranyl nitrate-induced acute renal failure, but the combined treatment group of sodium bicarbonate and saline with uranyl nitrate injection simultaneously and the dithiothreitol group that was administered 30 minutes after uranyl nitrate injection have the higher increment of fluid intake and urine volume(P<0.05). 3. When sodium bicarbonate and saline was treated with uranyl nitrate injection simultaneously, and dithiothreitol was administered 30 minutes after uranyl nitrate injection, there was significantly reduced in BUN concentration (P<0.0l). 4. When dithiothreitol was administered 30 minutes after uranyl nitrate injection, there was reduced more significantly on the increment of serum creatinine concentration than that observed in uranyl nitrate-only group(P<O.Ol). but when the combined treatment of sodium bicarbonate and saline with uranyl nitrate simultaneously, there was still, albeit much less marked, decrease in serum creatinine concentration. 5. The sodium bicarbonate and saline was treated with uranyl nitrate simultaneously and dithiothreitol was administered at 30 minutes after uranyl nitrate were excreted markedly higher urine creatinine concentration than the uranyl nitrate-only group. 6. Uranyl nitrate has been used in experimental animals to produce hydropic degeneration and swelling of proximal tubules, disappearance of microvilli and brush border or necrosis in the kidney and centrilobular necrosis, congestion, and telangiectasia of the liver. When the sodium bicarbonate and saline was treated with uranyl nitrate simultaneously, and dithiothreitol was administered 30 minutes after uranyl nitrate, there was more marked the protective effect than uranyl nitrate-only group. Finally, if the sodium bicarbonate and saline may administered as quickly as possible each time that some risk for internal contamination with uranium, and dithiothreitol is administered 30 minutes after uranium contamination, there ameliorates the course of uranyl nitrate-induced acute renal failure,and this effect is assocciated with prevention of uranium (heavy metal) induced alterations in BUN. serum creatinine. urine creatinine. fluid intake, urine volume and body weight.

1. The time of break point between Fast-component and slow component of O₂ up-take curve was presented at 12sec after recovery and its level of % VO₂max showed 32.18% VO₂max(Incremental) and 32.98% VO₂max(Continuous). 2. There were no significant differences of the break point between Incremental load and continuous load during recovery time. By above results, Though it was suggested that there will no problem for select any kind load exercise to evaluate O₂Debt during recovery time, but it shall be more desirable that Incremental load be applied to aged or women subjects and continuous load be applied to athletes or healthy subjects. To examine the level of % VO₂max which points the break point between Fast component and slow component by analyzing V E, VO₂, and LA concentration during recovery period after two kinds of treadmill exercise, 10healthy men(32.3%±4.72yrs) were tested as subjects. The methods of exercise load were Incremental load(start with 1.5mph, increasing the speed of 1.1mph at every 2min) and continuous load(continual running with the speed of 100% VO₂max level) with fixed 6% grade of treadmill. Results from the two kinds of load exercise are follows ;

Objective: To describe the therapeutic outcome of percutaneous vertebroplasty for the treatment of osteoporotic vertebral compression fractures(OVCF) in recent years with review of literature. Methods: The authors have retrospectively reviewed a consecutive group of patients who underwent percutaneous vertebroplasty in our institution between May 2000 and October 2002. The procedures were performed with Jamshidi needle via transpedicular approach followed by injection of polymethyl- methacrylate(PMMA) into the involved vertebral bodies. Prolo's economic and functional rating scale was used for therapeutic outcome assessments. Results: There were 91 patients(69 female, 22 male) with OVCF, with involvement of 147 vertebral bodies. The mean age was 72 years. The average BMD t-score was -3.78, indicative of severe osteoporosis. Minimal follow-up period was three months. And among these patients, 82.5% of patients were maintained over good condition. Extrusion of PMMA cement beyond the confines of the vertebral body was obseved in 13 cases(8.8%). Although most of them improved with conservative treatments without morbidities, two developed serious complications, one being pulmonary embolism and the other paraparesis. Conclusion: Percutaneous vertebroplasty is one of the effective minimal invasive treatment modalities in OVCF. However, proper biomechanical studies supporting these procedures are not fully evidenced. Serious complications, although rare, should be prevented with the aid of improved techniques and newer biocompatible materials along with better understanding of biodynamic and biomechanical impact on normal and already compromised vertebraes.

김성호,김태환,정인용,조철구,고경환,류성렬 대한방사선 방어학회 1992 방사선방어학회지 Vol.17 No.1

KCCH cyclotron neutron(30cCy/min) 및 ??Co γ-ray(210cGy/min)를 시험관내의 정상 인체 말초혈액임파구에 조사하여 염색체이상(dicentric 및 centric ring)을 관찰하고 이의 선량-반응관계식을 linear model(Y=K₁D+a), power-law model(Y=K₂Dⁿ), quadratic model(Y=K₃D²) 및 linear-quadratic model(Y=αD+βD²)을 사용하여 구하고 이들 model중 염색체이상의 측정치와 가장 일치하는 관계식을 근거로 하여 γ -ray에 대한 neutron의 relative biological effectiveness(RBE)를 산출하였다. 염색체 이상(dicentric plus centric ring)의 발생분포는 γ-ray의 경우 linear model(P=0.067)을 제외한 power-law model[Y=(5.81±1.96)×10??, P=0.931], quadratic model [Y=(3.91±0.09)×10?D², P=0.972] 및 linear-quadratic model [Y=(6.55±6.83)×10?D+(3.72±0.22)×10?D², P=0.922]에 적합하였다. Neutron의 경우 linear model [Y=(6.12±0.17)×10?³ D-022, P=0.987]에 가장 일치하였고 quadratic model (P<0.005)을 제외한 power-law model[Y=(2.43±0.70)×10?³D+(1.21±0.39)×10?D², P=0.415]에 비교적 적합하였다. 세포당 0.1-1.5개의 염색체이상을 나타내는 neutron의 γ-ray에 대한 RBE는 2.714±0.408이었다. The frequencies of KCCH cyclotron neutron(30cCy/min) or ??Co γ-ray(210cGy/min)-induced asymmetrical interchanges(dicentrics and centric ring) and acentric fragment(deletion) at several doses were measured in the normal human peripheral blood lymphocytes. Chromosome aberrations were scored at the first nitosis after stimulation with phytohemagglutinin. The neutron and γ-ray data were analysed on liner, power-law, quadratic and linear-quadratic model. When the dicentrics and centric rings of γ-ray datas were pooled and fitted to these model, good fits were obtained to power-law [Y=(5.81±1.96)×10??, P=0.931], quadratic [Y=(3.91±0.09)×10?D², P=0.972] 및 linear-quadratic model [Y=(6.55±6.83)×10?D+(3.72±0.22)×10?D², P=0.922] except for linear model(P=0.067). As in the case of neutron data, the best fits was obtained to the linear model [Y=(6.12±0.17)×10?³ D-022, P=0.987] and good fits were obtained to power-law[Y=(5.36±3.02)×10?⁴D??, P=0.601] and linear-quadratic model [Y=(2.43±0.70)×10?³D+(1.21±0.39)×10?D², P=0.415], except for quadratic model (P<0.005). The relative biological effectiveness(RBE) of neutron compared with γ-ray was estimated by best fitting model. In the asymmetrical interchanges range between 0.1 and 1.5 per cell, the REE was found to be 2.714±0.408.

The Purpose of this study is to investigate the influence of individual volume in the knee extensor muscles to the Maximum Voluntary Contraction(MVC). Five healthy male were subjeted in this study, age 26.6 ± 4.3yr, weight 71.2 ± 10.1 kg, body fat 13.6±4.9%, to evaluate morphological volume of knee extensor muscle with MRI(1.5 Tesla), which were carried out from femur length, seperated by 10mm thick and interval. A total of MRI scan was 44-49 number in each subject. Knee extensor muscles showed on MRI were identified, quantified with a computer scanner system. The MVCs were measured by using a straingage dynamometer system to knee angle 90°. In each muscle bundle area of knee extensor group, vastus laterialis were 695.78㎤ much more than orthers ; Vastus intermedins(571.18㎤), vastus medialis(509.81㎤), and rectus femoris(316.82㎤). However, there were significant relationships between MVC and vastus medialis(r=.93), a total extensor muscle areas(r=.94). These results suggest that vastus medialis volume is more important site to MVC than other sites in quadriceps femoris.
