Chin Mo Kim,Sam Jin Kim,Chul Sung Kim IEEE 2010 IEEE transactions on magnetics Vol.46 No.2

<P>FeCr<SUB>2-x</SUB>Al<SUB>x</SUB>S<SUB>4</SUB> ( x=0.1, 0.3, and 0.5) samples were prepared by solid state reaction method. The crystallographic structure and magnetic properties of the fabricated compounds were investigated by X-ray diffraction (XRD), superconducting quantum interference device (SQUID) magnetometer, and Mo¿ssbauer spectroscopy. The crystal structure is determined to be a cubic spinel with the space group of Fd-3m and the lattice constants <I>a</I> <SUB>0</SUB>= 9.998, 10.004, and 10.010 A¿ , respectively. The temperature dependence of magnetization, measured from 5 to 300 K, suggests that FeCr<SUB>2-x</SUB>Al<SUB>x</SUB>S<SUB>4</SUB> (x=0.1, 0.3, and 0.5) samples show ferrimagnetic behavior. The decrease of Ne¿el temperature compared with FeCr<SUB>2</SUB>S<SUB>4</SUB> could be interpreted by weakening of the exchange interaction by substitution of nonmagnetic Al ions. Mo¿ssbauer spectra of FeCr<SUB>2-x</SUB>Al<SUB>x</SUB>S<SUB>4</SUB> ( x= 0.1, 0.3, and 0.5) were obtained at various temperatures ranging from 4.2 to 300 K. Isomer shift values of the samples at various temperatures for FeCr<SUB>2-x</SUB>Al<SUB>x</SUB>S<SUB>4</SUB> (x=0.1 , 0.3, and 0.5) were 0.50 ¿ ¿ ¿ 0.73 mm/s, relative to the Fe metal, which are consistent with the Fe<SUP>2+</SUP> valence state.</P>

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.

흰쥐에서 반복적 스트레스가 GABA성 신경전달에 미치는 영향

김창수,이종범,성형모,시현석,김진성,박형배,정성덕,하정희 大韓神經精神醫學會 2000 신경정신의학 Vol.39 No.1

연구목적 : 일반적으로 생체는 각종 스트레스에 반응하여 적응(adaptation) 기전이 나타난다. 이러한 적응 기전과 관련하여 포유동물의 중요한 억제성 신경전달계인 GABA성 신경전달계의 스트레스성 자극에 대한 반응양상에 대한 연구가 진행되고 있다. 신경전달의 변화양상은 부하된 스트레스의 종류 및 기간에 따라 다양하게 나타나므로 더욱 상세한 연구를 필요로 한다. 방 법 : 본 연구에서는 하루 2시간의 부동화 스트레스를 반복적으로 2주간 부하한 흰쥐의 뇌조직에서 GABA성 신경전달의 변화 양상을 관찰하고자 하였다. 수용체 결합반응을 통하여 GABA 수용체의 각 component별 배위자들의 각 수용체에 대한 결합 반응의 변화 양상을 정상 대조군와 비교하여 보고, 유의한 변화가 있는 부분의 상세한 검정을 위하여 포화결합반응을 통하여 친화력(Kd) 및 최대결합력(Bmax)에서의 변화양상을 검색하였다. 뿐만 아니라 GABA성 신경전달에 관여하는 중요한 신경전달체인 내인성 GABA의 함량과 대사효소인 GABA transaminase의 활성도의 변화양상도 검색하였다. 결 과 : 연구결과 반복적인 부동화 스트레스는 GABA 수용체 효현제인 [³H]muscimol의 흰쥐 뇌조직 GABA 수용체에 대한 결합도에는 별다른 영향을 미치지 않았다. 대뇌피질조직의 GABA 대사효소인 GABA transaminase 활성도를 감소시켰으나, 피질조직외의 다른 조직의 GABA transaminase 활성도나 내인성 GABA의 농도에는 별다른 영향을 미치지 않았다. 반복적인 부동화 스트레스를 부하한 흰쥐의 대뇌피질, 해마 및 시상하부 조직에서는 [³H]flunitrazepam의 수용체 결합도가 감소하였으며, 포화결합 반응결과 수용체의 수가 감소하였음을 확인하였다. 결 론 : 이상의 결과를 요약하면, 흰쥐에게 부하한 반복적인 부동화 스트레스는 뇌조직의 benzodiazepine 수용체의 수를 감소시킴으로써 GABA성 신경전달을 감소시키며, 이러한 GABA성 신경전달계의 변환은 생체에서 스트레스로 인한 행동장애의 한 기전이 될 수 있을 것으로 생각되었다. Objectives : Changes of GABAergic neurotransmission in response to the application of different types of environmental stress have been the subject of research for over two decades. However, the nature of the changes induced by stress appear to show a dependent phenomena on the type and duration of stressor agent employed. Methods : For this reason, this study was performed to observe the effects of repeated stress on the radioligands binding to GABAA/benzodiazepine receptors of discrete brain regions. The author also examined the activity of GABA transaminase and the concentration of endogenous GABA. Male Sprague-Dawley rats, weighing 150-200g were forced to suffer an immobilization stress for 2 hours during 14 consecutive days. Results : Repeated immobilization stress decreased the binding of [3H]flunitrazepam on the benzodiazepine receptor in the cortex, hippocampus and hypothalamus. Saturation experiments followed by scatchard analyses of the results showed decreased density of benzodiazepine receptor and the affinity remained unchanged. Repeated immobilization stress did not affect the binding of [3H]muscimol on the GABAA receptor, the activity of GABA transaminase, and the concentration of endogenous GABA in the brain regions. Conclusions : From these results, it can be concluded that repeated immobilization stress modulated GABAergic neurotransmission via downregulation of the benzodiazepine receptor in the brain.

Objective: The purpose of the present study was to investigate relationship between autonomic neuropathy and diabetic complication through analysis of HRV(heart rate variability) of diabetic patients, and ultimately to investigate effectiveness of HRV analysis on evaluation and prediction of diabetic peripheral neuropathy. Method: We performed electromyogram, blood analysis and HRV test with 30 diabetic patients. By comparing SDNN(standard deviation of RR interval) of HRV, we analyzed the relationship between this parameter and duration of diabetes, age, and results from electromyogram. Results: 1) Averages of patients' age and the duration of diabetes were 56.12 ± 10.37, 14.58 ± 10.16, respectively. The relationship between each parameter of HRV was not significant(r<0.4). 2).When patients were classified according to the presence or the absence of H-reflex abnormality, peripheral neuropathy, gastrointestinal symptom When patients were classified by the degree of H-reflex abnormality and BUN(blood urea nitrogen), SDNN had reverse relationship to each other. Conclusion: Our results demonstrate HRV test shows statistically significant differences according to the absence or presence of diabetic peripheral neuropathy, gastrointestinal symptom. Therefore, we expect HRV analysis might be used as an efficient method to detect diabetic peripheral neuropathy, gastrointestinal disease, since it is relatively easy and convenient for both doctor and patient.
