결절성경화증 환자에서의 SPECT 뇌영상 : 예비적 연구 A preliminary report

한설희,이상수,정승연 충북대학교 의과대학 충북대학교 의학연구소 1991 忠北醫大學術誌 Vol.1 No.1

간질발작을 포함한 전형적인 삼징후가 동반된 결절성경화증 환자를 대상으로 뇌파검사, 뇌전산화단층촬영술 및 단일광자방출단층촬영술을 시행하였다. 뇌전산화단층촬영술에서는 상의하석회화병소와 조영제증강이 뚜렷하지 않은 피질에 연한 저음영 소견이 관찰되었으며 이어서 시행한 단일광자방출단층촬영술에서는 뇌전산화단층촬영술 소견보다 더 광범위한 부위에 관류결손이 관찰되었다. 단일광자방출단층촬영술은 결절성경화증 환자에서 간질발현 병소인 피질결절을 발견하는데 있어서 전산화단층촬영술 및 뇌파검사보다 더 유용한 방법이며 치료방침 결정이나 예후판정에 있어서도 큰 도움을 줄 것으로 기대된다. Two patients with a well-established diagnosis of tuberous sclerosis and epilepsies as their principal clinical symptom were examined by conventional surface electroencephalography(EEG), computed tomography, and single photon emission computed tomography(SPECT) using the 99mTc hexamethyl prophyleneamine oxime(99mTc-HMPAO). The interictal EEG showed various abnormalities of poor localizing value. Brain computed tomography surely demonstrated subependymal calcifications, although the cortical lesions were not so conspicuous. However, the SPECT images of each patient clearly demonstrated decreased cerebral perfusion in cortical areas. It may be assumed that such perfusion defect areas represent the epileptic cortical tubers or those of altered myelination, which are characteristics of the disease.

한설희 충북대학교 의과대학 충북대학교 의학연구소 1996 忠北醫大學術誌 Vol.6 No.2

원발성진행성실어증은 수년간에 걸쳐 대뇌고위 기능중 언어영역만 고립적으로 침범되어 서서히 진행하는데 임상적으로 치매와 구별되어야 하는 비교적 드문 증후군이다. 저자는 최근에 62세 여자환자가 약 4년간에 걸쳐 서서히 진행한 언어장애를 주소로 본원 치매크리닉을 방문하여 신경심리검사, 뇌파검사, 뇌핵자기공면영상, 단일광자방출단층촬영술 등에서 전형적인 원발성진행성실어증으로 확인된 우리 나라 최초의 예를 경험하였기에 간단한 문헌고찰과 함께 보고하는 바이다. A 62-year-old right-handed woman presented with a progressive deterioration in her ability to name common object used in everyday life. Her initial language disturbance, word-finding difficulty, got worsened gradually over the next 4 years, She was able to point to the correct object when the word is provided by the examiner despite being unable to name it spontaneously. Her memory, attention, visuospatial skills and comportment were all intact. She is doing well in her daily living activities including taking care of herself, shopping and paying bills. MRI showed left perisylvian atrophy and dilated left frontal horn. SPECT study revealed decreased perfusion in left temporal lobe. Her clinical presentation together with the characteristic structural and functional neuroimaging findings were typical of 'primary progressive aphasia'.

경도인지장애 : 알쯔하이머병의 초기단계인가? Is it an Early Stage of Alzheimer's Disease?

한설희 대한치매학회 2003 Dementia and Neurocognitive Disorders Vol.2 No.2

Aging causes deterioration of various aspects of memory performance in norma adults In recent years. a great deal of interest has been generated around the concept of a boundary or transitional state between normal aging and dementia or, more specifically, Alzheimer's disease (AD). This condition has received a number of descriptions including incipient dementia. questionable dementia. age-associated cognitive decline, isolated memory impairment and mild cognitive impairment (MCI) Commonly accepted guidelines for MCI have been established-memory complaint, preferably corroborated by an informant. objective memory impairment for age and education. normal general cognition, preserved activities of daily living, and not demented The precise definitions need to be explicated. but these will probably simply be a refinement of a concept. rather than a major re-definition Importantly, clinical and neurobiological evidence suggests that patients with MCI are at an increased risk for developing AD. Current research efforts are geared with MCI are at an increased risk for developing AD. Current research efforts are geared towards intervention strategies aimed at preventing the development of AD among persons with MCI.

치매환자의 비인지 기능장애에 관한 예비적 연구

한설희 충북대학교 의과대학 충북대학교 의학연구소 1999 忠北醫大學術誌 Vol.9 No.2

연구목적: 행동장애/행동이상(behavioral disturbances)는 치매환자에서 비교적 흔히 관찰되는 증상이기는 하나 기억장애와 같은 인지기능이상이 두드러진 현상이기 때문에 최근까지 연구대상에서 제외되어 있었다. 그러나 환자들이 나타내는 비인지기능 증상들 (non-cognitive symptoms; NCS)은 치매의 진단, 예후 및 치료에 있어 매우 중요한 의미를 갖는다. 본 연구의 목적은 치매환자의 NCS의 임상적 특징을 면밀히 파악하여 향후 치매환자의 치료에 있어 인지기능을 개선시키려는 노력 이외에 NCS에 대한 적극적인 치료방침을 마련하는 데 있다. 대상 및 방법: 충북대학교병원 치매크리닉에 내원한 환자중 DSM IV 및 NINDS-ADRDA 진단기준에 맞는 알쯔하이머형 치매환자 42명, NINDS-AIREN 진단기준에 적합한 혈관성치매환자 13명, 혼합형치매환자 12명을 대상으로하여 이상행동적도를 평가하였다. 결과: 치매척도인 Hasegawa scale과 행동척도인 Behavioral Rating Scalerks의 상관지수는 0.805로 상당한 유의성이 관찰되었다. 질병의 종류에 무관하게 과격한 행동, 밤-낮의 뒤바뀜, 초조증 등이 가장 흔히 관찰되는 행동장애이었다. 결론: 본 연구의 결과 치매환자의 치료에 있어 비인지기능장애의 중요성을 인식할 수 있었으며 이를 조기에 발견 치료해줌으로써 환자들를 돌보는 간호인력이나 보호자들의 삶의 질을 향상시키는데 많은 기여를 할 것으로 기대된다. 비인지기능 장애의 발병기전을 밝히기 위하여 향후 좀더 잘 기획된 전향적 방법으로 치매환자에서 비인지기능 장애가 어떻게 진행되는 가에 대한 추시 연구가 필요할 것으로 생각된다. Purpose: Behavioral symptoms in dementias, although common, have not received much attention until recently. This report attempts to describe the frequencies and characteristics of such symptoms in patients with dementia. Materials and Methods : The author cross-sectionally investigated the prevalence, phenomenolgy, and clinical correaltes of noncognitive symptoms (NCS) in a consecutive series of 67 patients with dementia (42 with Alzheimer's disease, 13 with vascular dementia, 12 with mixed dementia). Cognitive function was rated using the Hasegawa scale and NCS was measured with modified Behavioral Rating Scale (BRS). Results: The correlation between Hasegawa scale and BRS was 0.805 at the time of initial evaluation. Among various delusional symptoms, picture sign was noted only in patients with Alzheimer's disease. Aggressive behavior, day-night-disturbances, and agitation were most frequently observed NCS regardless of disease entities. Conclusion: The findings of the present study underlie the importance of NCS in the management of patients with dementia. Further longitudinal study using well-designed structured interview should be performed to clarify the evolution of NCS in patients with dementia.

This paper presents the thermal characteristics analysis of a high-speed HMC spindle system with angular contact ball bearings, built-in motor, oil-jet lubrication method, oil jacket cooling method, and so on. The spindle system is composed of the main spindle and sub-spindle which are mechanically connected by a flexible coupling. The spindles are supported by two front and rear bearings, and the built-in motor is located between the front and rear bearings of the sub-spindle. The thermal analysis model of spindle system is constructed by the finite element method, and the thermal characteristics in the design stage are estimated based on temperature distribution and heat flow under the various testing conditions related to material of bearing ball, spindle speed and coolant temperature.

김관 평론과 '민족음악'론

신설령 민족음악학회 2004 음악과 민족 Vol.28 No.-

Since there were few musical critics in 1930s, Kim Guan proposed the reexamination of "the national music." During this era, there were no support or exchanging of views from his fellow musical critics toward his proposal. Many believed that because of the closely monitored Japanese imperialism, they were intimidated to express their points of views and support for Kim's, "the national music." Besides of being suppressed, many found that Kim's opinion were very ahead of time or very futuristic and therefore, it didn't get the importance of its issues. After the independence from Japan, there were bursts of discussions about his proposal as like the darn water exploded. Many people including the musical critics were able to express their views towards the proposal. They could sing for joy during the independence. In 1980s, the systematic written exposition or argument about Korean music could point out and discussed the problems of the western music influences. However, during the occupation of the Japanese, there was one musical critic who gave his valuable opinion on "the national music" --- Kim Guan. Even though there was no freedom, there was advancement and it led the Korean music where it is today.

한설희,이건국,양기화,장순환 대한치매학회 2002 Dementia and Neurocognitive Disorders Vol.1 No.1

While the clinical diagnostic accuracy of probable Alzheimer′s disease (AD) is 87-96% with a diagnostic sensitivity/specificity of 0 81-0 87, the unequivocal diagnosis of AD rests on histopathological evidence at brain autopsy and/or biopsy We report here a 92-year-old woman whose clinical presentation suggested a far advanced Alzheimer′s disease Formal neuropsychological evaluations were not applicable due to severe cognitive impairments With a relatively good general physical condition she could walk with aid during her last days no focal neurological signs were noted on a detailed examination Brain MRI revealed a diffuse cortical atrophy with a marked reduction in the hippocampal volume The brain obtained weighted 780g The cerebral hemispheres examined after fixation disclosed moderately severe atrophy in prefrontal and temporal lobes on coronal section, the hippocampus was likewise severely atrophied the lateral ventricles were moderately dilated On microscope examination, there were numerous senile plaques and neurofibrillary tangles in the neocortices. hippocampus and amyglada, compatible with advanced Alzheimer′s disease In summary we report the first Korean autopsy-proven case with advanced Alzheimer′s disease.

Gerstmann 증후군을 동반한 교차 실어증 1례 : MRI 및 SPECT를 이용한 연구

한설희 충북대학교 의학연구소 2001 忠北醫大學術誌 Vol.11 No.1

교차실어증이란 오른손잡이 환자에서 우측 대뇌 반구 손상후에 언어장애(실어증)가 발생한 경우를 말한다.오른손잡이 실어증 환자의 약 1%-2%에서 교차실어증이 발생하는 것으로 알려져 있으나 구조적 병변이 잘 밝혀진 예는 드물다.더욱이 우뇌 손상과 관련된 좌, 우 지남력 상실, 수지 실인증, 계산불능증, 필기불능증의 4 가지 임상 특징을 가지는 Gerstmann 증후군의 예는 더욱 드물다.저자는 MRI 및 SPECT 뇌영상 검사로 우뇌 경색이 확인된 오른손잡이 환자에서 Gerstmann 증후군과 교차실어증이 동시에 발생한 드문 예를 경험하였기에 문헌 고찰과 함께 보고하는 바이다. Crossed aphasia refers to disturbance of language following a right hemisphere lesion in right handed individuals.Although it is estimated to occur in 1% to 2% of all dextral aphasic, well documented cases of crossed aphasia continue to be rare.Moreover, it is also rare to see a Gerstmann's syndrome (left-right disorientation, finger agnosia, dyscalculia, and dysgraphia) in right hemispheric lesion.In this paper, the author presents one case of crossed aphasia associated with Gerstmann syndrome in monolingual right handed patient. This case is found interesting to be reported because it is a extremely rare condition where a crossed aphasia and a Gerstmann syndrome are simultaneously seen in the same patient.

백서 뇌에서의 Nitric Oxide Synthase를 함유한 신경세포의 분포에 관한 연구 : 해마 구조를 중심으로 An NADPH-diaphorase Histochemical Study

한설희 충북대학교 의과대학 충북대학교 의학연구소 1996 忠北醫大學術誌 Vol.6 No.1

뇌에 존재하는 어떤 종류의 신경세포는 nicotinamide adenin dinucleotide phosphate-diaphorase (NADPH-d) 활성을 함유하고 있어 조직화학 기법에 의해 특이성을 가지며 강하게 염색된다. NADPH-d에 염색되는 신경 세포들은 다양한 종류의 신경 독성과 퇴행성 신경변성에 대하여 강한 저항성을 나타내는 것으로 알려져 있다. 또한 NADPH-d는 formaldehyde에 저항성을 나타내는 조직화학적 특성을 가지고 있으며 이는 nitric oxide synthase (NOS) 성질과 동일하다. 따라서 NADPH-d는 formaldehyde로 고정된 신경조직에서 NOS의 활성을 가진 신뢰성 높은 조직화학지표로 생각된다. 본 연구에서는 백서 뇌조직 중 해마에서의 NOS표현을 알아보기 위해 NADPH-d 조직화학 기법을 사용하였다. Certain neurons in the brain are specifically and intensely stained by a histochemical method which demonstrates nicotinamide adenine dinucleotide phosphate-diaphorase (NADPH-d) activity. These NADPH-d positive neurons are known to exhibit high resistance to various neurotoxins and to neurodegeneration. NADPH-d is a formaldehyde-resistant histochemical activity which has been shown to be exerted by nitric oxide synthase (NOS). Thus NADPH-d serve as a reliable histochemical marker for NOS in formaldehyde-fixed sections of neural tissue, the present study uses NADPH-diaphorase histochemistry to see the expression of NOS in the rat hippocampus.
