Stenosis of central vein is a common complication arising after percutaneous subclavian vein catheter insertion performed for temporary vascular access in chronic renal failure patients undergoing hemodialysis. There are several treatment methods for the condition like percutaneous angioplasty(PTA), stent insertion, and surgery, but recent trend is toward PTA and stents. Among the patients diagnosed with chronic renal failure from March 1993 to May 2002 and undergoing hemodialysis through AV fistula, the 14 Patients in whom central vein stenosis arose were selected for the study. A total of 28 percutaneous interventions(5 PTA and 23 stent placement) were performed, and restenosis rate and the time taken till the restenosis in de novo lesions and instant lesions were compared. All 28 cases were operated successfully. The 14 cases that received both anigioplasty and stent placement initially. (de novo lesion : 14 cases), Among the 10 cases with de novo lesion that followed up more than 1 year, 3 cases are currently undergoing hemodialysis without restenosis, and the remaining 7 cases have recurred stenosis with the mean time to restenosis of 10.9 months. In the 7 cases in whom stenosis recurred, 11 interventions were done(instent lesion: 11 cases). 4 of these were using only ballon angioplasty with 100% restenosis rate and the mean time of 3 months until restenosis. The remaining 7 cases were using both balloon angioplasty and stent placement, also with 100% restenosis rate but with the mean time of 12 months until restenosis, which was later than the group receiving only balloon angioplasty. In treating the patients with central vein stenosis, stent placement seems to be more advantageous over PTA in terms of restenosis rate and the mean duration of patency. In the case of instent lesion, inserting the stent for the second time after stenosis recurred lengthened the duration of patency compared to performing balloon angioplasty alone.

Acinetobacter species is a non-fermentative aerobic gram-negative coccobacillus that is an important pathogen found in nosocomial infections. Recently, multi-drug resistant Acinetobacter baumannii (MDR-AB) infections have been increasing and pose a serious problem. Most such infections present as bacteremia, pneumonia, or a wound infection; however, CNS infections are very rare. We herein present a case of ventriculitis caused by MDR-AB in a 37-year old man after a neurosurgical intervention. The patient was successfully treated with intrathecal colistimethate.

이형재,김영기,신영진,박해용,정양준,최춘태,김병호,김진성 全北大學校 基礎科學硏究所 1982 基礎科學 Vol.5 No.1

Temperature of 618 and 1250℃ at As and Ga sities respectively in the horizontal Bridgman furnace and growht speed of 0.7cm/h were found to be optimal for the production of single crystalline GaAs. Self-seeded and unintentionally doped GaAs crystals showd n-type characteristics with Hall mobillity of ∼0.75㎡/V-sec and carrier density of ∼10^19 m^-3 when the mesurements were made right after the growth. About three month later it was found that the same samples were converted to p-type GaAs. The analysis on the p-type sample showed that impurity scattering is dominant at around room temperature and thus the measured Hall mobility was 0.0065㎡/V-sec at 300K. 7.4±0.6 eV was obtained for acoustic deformation potential in the heavy hole band by fitting the theoretical conductivity and Hall coefficient to the corresponding experimental data. The value is very much higher than the theoretically estimated value, 3.6eV. The carrier density variation with temperature obtained from the present analysis gave 0.38 and 0.17 eV respectively for the activation energies of donor and acceptor.

The fungal sinusitis is relatively rare and mainly develops in immunocompromised hosts, but is sporadically appears in the immunocompetent patients, where its incidence tends to be increasing. Because the clinical features of this disease are similar to those of chronic suppurative sinusitis, this entity may be overlooked. We analysed thirteen fungal sinusitis from January 1997 through December 1999 based on clinical features, laboratory characteristics and operative findings. The results are as follows. 1)Fungal sinusitis occurred 3.3 times as frequently in female patients as in male patients and the peak age groups are 4th and 5th decades. 2) The time intervals between the onset of symptoms and the first hospital visit were as follows: 5 cases within 3 months, 1 case between 4 and 6 months, 3 cases between 7 and 12 months, and 4 cases over 1 year. 3) The chief complaints were nasal obstruction, postnasal drip, rhinorrhea, cheek pain, headache, ocular pain, sneezing. 4) The characteristic computerized tomographic findings were hyperattenuated lesions in the maxillary sinus and in the nasal cavity near the natural ostium. 5) The most common pathogen was Aspergillus(92.3%) 6) We performed Caldwell-Luc's operation only in 4 cases, Caldwell-Luc's operation with intranasal ethmoidectomy in 3 cases, Caldwell-Luc's operation with endoscopic sinus surgery in 3 cases and endoscopic sinus sugery only in 3 cases. 7) Most of the gross specimens revealed a fungus ball containing a black-brown necrotic debris or caseous material.

For more than two decades, many investigators have tried a variety of methods for delivering antimicrobial agents to the oral cavity with the objective of eliminating mutans streptococci. In the belief that the effectiveness of chemotherapy might be improved by a more effective delivery system, the intention of the present study was to exploit a new drug delivery system delivering chlorhexidine to the oral cavity. The vehicle delivering chlorhexidine tested in this study was self-curing acrylic resin(polymethy1 methacrylate). The powder of the acrylic resin was polymerized with the 5 different liquid preparations, in which chlorzoin was mixed with five different monomer/chlorzoin ratios immediately prior to the polymerizatin, in a stainless, steel mold (40mmx40mmx2mm). A total of 50 cured resin specimens were divided into 5 groups according to the different monomer preparations. Every specimen was soaked in an airtight container filled with distilled water(100 ml) and then kept in an incubator at 37℃. The solutions(0.8ml) were collected from the container at every 24 hours, and the amount of released chlorhexidint in the solutions was measured in an ultraviolet spectrophotometer at 250㎚. The container was refilled with distilled water every after measurement. this procedure was repeated for 14 days. It was found that chiorhexidine was continuously released from all of the 50 specimens during the experimental period. And it was note that the pattern of chlorhexidine release was a type of sustained-release preparation, that is, the amount of the released chlorhexidine at the first day in all 5 groups was high (p<0.0001), and then the release was decreased during the rest of the experimental period ([<0.0001).

요약문사출성형법으로 평가를 위해 ZnO 함량을 변화시키면서 4종류의 Zinc Titanate 흡수제를 제조하였다. Zn/Ti 몰비가 증가할수록 지배적인 결정상은 Zn 2Ti3O8과 Zn2TiO4로 관찰되었다. Zinc Titanate 탈황제에 의한 H2S 흡수반응을 모사석탄가스의 고온탈황에 의해서 실험적으로 연구하였다. 내경 3cm인 석영관의 고정상 반응기로 4종류의 Zin cTitanate 흡수제에 대하여 H2S 흡수와 재생의 10-cycle 실험을 수행하였다. 파과곡선, SEM, BET 등의 실험적인 관찰을 근거로 하여 650℃가 최적 흡수반응온도임을 결정하였다. 탈황과 재생의 반복적인 실험동안 H2S와 S02의 파과곡선들을 구하였다. 또한, 시험 전후의 흡수제의 물성변화를 SEM, EDX, Hg-porosimetry 및 BET 방법으로 분석하였다. 비록 더많은 연구가 필요하지만, 제한된 실험적 조건에서 판단하면 YZT-3(Zn/Ti=1.5)가 가장 우수한 탈황제라고 결론내릴 수 있다.AbstractFour zinc titanate sorbents were prepared for evaluation by extrusion method with varying ZnO contents. The predominant crystalline phases were Zn2Ti3O3 and Zn2TiO4 as Zn/Ti molar ratio was increased. Absorption of HzS by the zinc titanate sorbents was studied experimentally in high temperature desulfurization of simulated coal gas. Fixed-bed system of 3 cm i. d. quartz tube was used to carry out 10-cycle experiments of H2S absorption and regeneration for the zinc titanate sorbents. In these experiments the optimal absorption temperature was determined as 650 ℃ based on experimental observation of breakthrough curves, SEM and BET results, and so on. H2S and SO; breakthrough curves were obtained for each sorbent during repetitive cycles of desulfurization and regeneration. Also, property changes of the sorbent before and after testing were analyzed using SEM, EDX, XRD, Hg-porosimeter and BET method. It is concluded under this limited experimental conditions YZT-3 (Zn/Ti =1.5) was the most suitable desulfurization sorbent even though further tests are required.
