1.Pharmacological Treatments of Behavioral Symptoms in Dementia.
Journal of the Korean Medical Association 2002;45(4):415-420
Behavioral symptoms are well-recognized concomitants of the progression of dementia. These symptoms include agitation, aggression, anxiety, depression, disinhibition, delusions, hallucination, and sleep disturbance. Because these symptoms are a major source of impaired quality of life for patients and their caregivers, appropriate pharmacological management of them may reduce the burden of caregivers and postpone institutionalization. Furthermore, behavioral symptoms may be more amenable to pharmacological intervention than cognitive symptoms. For that reason, detailed evaluation and appropriate treatment are the mainstay in the management of dementia patients. In this article, we reviewed symptomatology and psychopharmacology for behavioral symptoms of dementia.

2.Symptomatology of Dementia.
Journal of Korean Geriatric Psychiatry 1997;1(1):34-47
Dementia can be defined as an acquired persistent impairment of intellectual func-tion with compromise in at least three of the mental activities such as language, memory, visuospatial skill, emotion or personality, and cognition. The purposes of diagnosing a dementia syndrome are to search systemically for various etiologies, to differentiate reversible or irreversible dementia, cortical or subcortical dementia, and degenerative or nondegenerative dementia, and to apply to patients neurocognitive rehabilitation or other specific trea-tment strategies. The evaluation of dementia includes neuropsychiatric history taking, neuropsychological assessment, neurologic examination, neuroimaging studies, and laboratory studies. It is impossible to evaluate dementic patients only with clinical signs, symptoms, and neuropsychiatric histories. But I will address specific neurologic or neuropsychiatric symptoms and signs of various dementias to und-erstand them as classification.

BACKGROUND: Vascular dementia is common cause of dementia, second to the dementia of Alzheimer desease. However in Asia and many developing countries, the incidence of vascular dementia exceeds that of Alzheimer's disease. Though many stroke-related factors related the nature of vascular injury, e.g. infarction and hemorrhage, have not assessed yet. Clarifying the difference of electroencephalograpy and clinical prognosis between infarction and hemorrhage, the aim of this study was to elucidate the role of nature of vascular injury. METHODS: to reduce confounding factors, the study population was restricted to the patients of single hemispheric striatocapsular infarction and hemorrhage saving cortex. On admission, we checked the KMMSE and FIM scores and using quantified EEG, we analyzed occipital peak frequency and the relative background alpha, theta and delta spectra power taken from 16 derivations by averaging twenty-2 -sec epoch in infarction, hemorrhage patients and elderly controls. After 6 months follow up, we compare the MMSE, FIM score between infarction and hemorrhage group. RESULTS: 1) Compared with infarction group, hemorrhage groups had a significantly bilateral lower occipital peak freqauency and background bilateral alpha spectra power. 2) In hemorrhage group, there is lower tendency in K-MMSE after 6 month follow up compared to infarction group. CONCLUSION: This study suggests that hemorrhage show more bilateral electrophysiological dysfunction than infarction group and possible grave prognosis for vascular dementia compared to infarction group.

4.Memory Impairment in Dementing Patients.
Sleep Medicine and Psychophysiology 1997;4(1):29-38
Dementia is defined as a syndrome which is characterized by various impairments in cognitive functions, especially memory function, Most of the diagnostic criteria for dementia include memory impairment as no essential feature. Memory decline can be present as a consequence of the aging process, But it does not cause significant distress or impairment in social and occupational functionings while dementiadoes. Depression may also be associated with memory impairment. funcitionings while dementiadoes. Depression may also be associated with memory impairment. However, unlike dementia, depression dose not cause decrease in delayed verbal learning and recognition memory. In dementia, different features of memory impairment may be present depending on the involved area. Memory impairment in cortical dementia is affected by the disturbance of encoding of information and memory consolidation, while memory imparnene in subcrotical denentiy is affected y the disturbance of retrieval in subcortial dementia.

The status of DNA synthesis and the effect of UV radiation on the DNA synthesis were studied in mouse skin by microautoradiography. Mice exposed to 100mJ/cm of UVB were injected intradermally with tritiated thymidine, 5 minutes, 2, 6 and 24 hours after irradiation and biopsies were processed for light microscopic autoradiography, A total of 25 ICR female albino haired mice were used as subjects. We compared heavily labeled cells(>10 grains/nucleus) and sparsely labeled cells (3-10 grains/nucleus) in UVL irradiated skin with nonirradiated control skin. 1. Within 5 minutes after UVL exposure an apparent depression in the number of heavily labeled cells occurred. This reduction was statistically significant and remained so for at least six hours post,irradiation. By 24 hours after UVL exposure, the reduction was recovered to nearly control level. 2. By five minutes after UVL exposure, sparsely labeled cells were observed in basal cell layer and differentiated cell layer. The nurriber of sparsely labeled cells appeared highest at five minutes after UVL exposure and then tended to fall to nearly control level at 24 hours. This aberrant type of TdR H incorporation is thought to represent unscheduled DNA synthesis to repair pyrimidine dimers formed in UVL injured DNA molecules,

Microvascular anastomosis has become an essential technique in reconstructive surgery. A lot of techniques have been developed to improve patency rate and reduce operation time. But interrupted suture technique is still most widely used because of limited indication and inconvenience of other methods. A comparative study was undertaken to evaluate new microvasular anastomosis technique using fibrin glue. In this report 40 femoral arteries of Sprague-Dawley rats were anastomosed by utilizing four stay sutures which were placed 90 degrees apart and the intervals covered with fibrin glue, and by conventional eight suture method served as control. The patency rate(immediate postoperative, postoperative two weeks), time needed for vascular anastomosis, and microscopic evaluation were compared to those of conventional microvascular suture technique. Postoperative patency rate was 100% and 85% by fibrin glue technique compared to 100% and 90% by conventional technique at immediate postoperative and postoperative two weeks. Less time consumed with fibrin glue technique by 16 minutes compared to conventional technique by 21 minutes. Microscopically reendothelization was complete with smooth and less injured inner lining and also less inflammatory response by fibrin glue technique compared to conventional technique.

8.Treatment and Management of Senile Dementia.
Journal of Korean Geriatric Psychiatry 1999;3(1):32-39
There are about sixty to seventy diseases which develop dementia until now. These include degenerative disease, vascular disease, infectious disease, hydrocephalus, toxic condition, head trauma, tumor , metabolic disease, and demyelinating disease etc. 20% of dementing illness is reversible to treatment. Treatment strategies of dementia can be classified as disease-specific treatment, pharmacotherapy with neurocognitive activators or psychopharmacologic agents, and nonpharmacologic intervention such as neurocognitive rehabilitation, reminiscence therapy, occupational or physical therapy, and psychosocial approach. But medical approach is necessary to prevent disability stemming from pneumonia, dehydration, malnutrition, decubitus ulcer, and other complication. These treatment strategies must be administered comprehensibly due to characteristics of the dementia patients.

One hundred seven isolates of Staphylococcus aureus from bovine mastitis were investigated for colony morphology in serum-soft agar (SSA), autoagglutination in salt, and capsular serotype. Capsular polysaccharide (CP) was purified and quantified from the extracts of clinical isolates. Overall, 89 isolates (83.2%) were diffuse in the SSA, without any difference in the proportion of diffuse colony between type 5 and type 8 strains. Some strains exhibited compact colonies in the SSA and expressed CP as determined by an enzyme-linked immunosorbent assay, indicating that compact morphology does not exclude encapsulation. The majority of the strains (11/12) showed autoagglutination in the salt aggregation test. The serotype 336 accounted for 46.7% of the isolates followed by serotype 5 (12.1%) and serotype 8 (12.1%). Particularly, twenty-six (24.3%) isolates reacted with two serotypes; 7 for type 8/336 and 19 for type 5/336. Five isolates (4.7%) were nontypeable with monoclonal antibodies specific for CP serotype 5, 8, or 336. The CP concentration in culture supernatants varied with the serotypes, and the total amount of CP produced by cells grown in a liquid medium was much less than that produced by cells grown on a solid medium. The Western blotting indicated that the CP bands of S. aureus serotype 5 and 8 were ranged in the molecular mass of 58-84 kilodalton (kDa), with additional bands in the region of approximately >or= 48 or
