Objectives: The purpose of this study was to evaluate diagnostic value of Transcranial Doppler Ultrasound about risk factor of stroke by comparing blood flow between patients with metabolic syndrome(MS group) and Normal group. Methods: 62 metabolic syndrome patients and 106 healthy adults were selected who had no cerebrovascular diseases, cardiovascular diseases and other systemic diseases. We measured the mean velocity(Vm), peak systolic velocity(Vs) and pulsatility index(PI) of MCA, ACA, PCA, VA, ICA in two groups using TCD. All subjects were divided by gender and age. Results: In comparing Ms group with normal group, Vm in the MCA, ACA, PCA, ICA and Vs in the MCA, ICA were lower in MS group. In all vessels, PI of MS group were higher than that of Normal group. In all vessels, Vm and Vs revealed negative correlation with age and PI revealed positive correlation with age. In 20-39 year olds, there was decrease in the Vs and Vm and increase of PI of MS group in comparison with normal group. There was significant difference in the Vm of PCA, ICA, Vs of MCA, PCA, ICA and PI of MCA, ACA. In 40-59 year olds, Vm in the MCA, ACA, ICA and Vs in the MCA, ACA were lower in MS group. PI in the MCA, ACA, PCA, ICA were higher in MS group. In 60-79 year olds, Vm of MCA, PCA, ICA was decreased in MS group than Normal group with no statistical signification. Vs in the MCA was lower and PI in the PCA was higher in MS group. In male, Vm of PCA and Vs of MCA were lower and PI of MCA, ACA, PCA, ICA were higher in MS group. In female, Vm of MCA, PCA, ICA and Vs of MCA, ICA were lower and PI of ACA, PCA, VA, ICA were higher in MS group. Conclusions: The significant difference in Vm, Vs, PI between MS group and normal group suggests hemodynamic disorder. Screening and prognosing high risk group can be done through TCD and this can be used to prevent stroke. More detailed study will be needed.

Insomnia describes not only a state of a lack of sleep but also a causative factor for both psychological and physical disorders. Most people tend to underestimate the effects of insomnia on psychological problems, stroke, Sogal or other life-threatening conditions. insomnia may occur when 1) the flow of Jung(精), Ki(氣), Shin(神) and Hyul(血) is not smooth; 2) the five Jang organs and six Bu organs are in disharmony; 3) Shin(身) and Hyung(形) are inconsistently developed; 4) Young and Wi(衛) do not work in concert; 5) and other factors such as age or exposure to Cold are involved. I observed my patients suffering from insomnia according to Hyungsang medicine, which is based on 'Dongyuibogam'(東醫寶鑑). Insomnia due to the problems with Jung, Ki. Shin and Hyul was found in the Shin type(神科) and the Ki type(氣科). When it comes to the organs, sleep disorder significantly correlates to weakened Spleen, Liver and Kidneys. In terms of the inconsistent development of Shin and Hyung, patients who were shortsighted or experienced surgery showed insomnia. Patients exposed to Cold showed false type agitation. With respect to age, while children showed a weakened Gallbladder, the aged had deficient Blood. Sleep disorder caused by disharmony of Young and Wi occurs at dusk or dawn.

The decrease of masticatory function caused by tooth loss leads to a decrease of cerebral blood flow volume resulting in impairment of cognitive function and learning memory disorder. However, the reduced mastication-mediated morphological alteration in the central nervous system (CNS) responsible for senile deficit of cognition, learning and memory has not been well documented. In this study, the effect of the loss of the molar teeth (molarless condition) on the hippocampal expression of glial fibrillary acidic protein (GFAP) protein was studied by immunohistochemical techniques. The results were as follows : 1. The molarless mice showed a lower density of pyramidal cells in the cornu ammonis 1 (CA1) and dentate gyrus (DG) region of the hippocampus than control mice. 2. Immunohistochemical analysis showed that the molarless condition enhanced the time-dependent increase in the cell density and hypertrophy of GFAP immunoreactivity in the CA1 region of the hippocampus. The molarless condition enhanced an time-dependent decrease in the number of neurons in the hippocampal formation and the time-dependent increase in the number and hypertrophy of GFAP-labeled cells in the same region. The data suggest a possible link between reduced mastication and histological changes in hippocampal formation that may be one risk factor for senile impairment of cognitive function and spatial learning memory.

Inherited platelet function disorders (IPFDs) are a disease group of heterogeneous bleeding disorders associated with congenital defects of platelet functions. Normal platelets essential role for primary hemostasis by adhesion, activation, secretion of granules, aggregation, and procoagulant activity of platelets. The accurate diagnosis of IPFDs is challenging due to unavailability of important testing methods, including light transmission aggregometry and flow cytometry, in several medical centers in Korea. Among several IPFDs, Glanzmann thrombasthenia (GT) is a most representative IPFD and is relatively frequently found compare to the other types of rarer IPFDs. GT is an autosomal recessive disorder caused by mutations of ITGA2B or ITGB3. There are quantitative or qualitative defects of the GPIIb/IIIa complex in platelet, which is the binding receptor for fibrinogen, von Willbrand factor, and fibronectin in GT patients. Therefore, patients with GT have normal platelet count and normal platelet morphology, but they have severely decreased platelet aggregation. Thus, GT patients have a very severe hemorrhagic phenotypes that begins at a very early age and persists throughout life. In this article, the general contents about platelet functions and respective IPFDs, the overall contents of GT, and the current status of genetic diagnosis of GT in Korea will be reviewed.

Jiu Qi(九氣) was shown at Ju Tong Lun(擧痛論) in Shao Wen(素問) Huang Ti Nei Ching(黃帝內經), and is nine important factors that affect the function of human body. Jiu Qi concludes endogenous, exogenous, non-endo-exogenous factors. I do the bibliographical study on the Jiu Qi, the results were as follows; 1. The Qi of Jiu Qi has two opposite meanings. one is genuine vital energy(正氣), and the other is the factors causing abnormal state in vital energy. Jiu Qi is nine factors concluding coldness-heat(exogenous factors). six emotional factors(endogenous factor), overworking(non -endo-exogenous factor). 2. Anger may lead to abnormal rising of vital energy. Anger causes Qi of the liver to go perversely upward, and perverted flow of exuberant Qi of the liver lead to dysfunction of the spleen, so resulted in hematemesis, diarrhea, indigestion. 3. Joy can promote the harmony of vital energy and blood, so do the circulation of nutrient and defensive energy in physiological state. But an excessive joy may lead to the sluggishness of vital energy. 4. The lung keeps the pathway of air unconstructed, disseminates vital energy, cleanses the inspired air and keeps vital energy flowing downward. Sorrow affects on the function of the lung and the heart, so could result in obstruction of the circulation of nutrient and defensive energy. An excessive sorrow after stagnation may lead to the consumption of vital energy. 5. Fear makes vital energy and essence of the kidney sink to inward and downside, makes Yang-Qi can't go upward, so causes obstruction of triple wanner. An excessive fear can obstructs the ascending of Yang-Qi, so may lead to the abnormal falling of vital energy. 6. Coldness makes the sweat pore be contracted, so obstructs the circulation of triple warmer, causes sluggishness of defensive energy or Qi of the internal organ. 7. Heat makes the sweat pore be open, much amount of sweat is excreted with Yang-Qi, defensive energy, vital energy. Heat may consume vital energy. 8. Sudden fright affects on spirits of the heart and liver, causes disorder of the mental faculties and separation of blood and vital energy. Fright may lead to disorder of Qi. 9. Overwork concludes overfatigue and exhaustion caused by intemperance in sexual life. Overwork renders vital energy consumed, and hence results in lassitude and listlessness. 10. Thinking affects on the function of the heart and the spleen. Over thinking may lead to depression of vital energy. Through the bibliographical study on Jiu Qi, I got smallest amount of it, and this must be more investigated correlating with clinical study.

발달성언어장애는 학령기 아동에서 약 $3{\sim}10%의$ 높은 빈도로 발견이 되며 그대로 방치할 경우 열등감, 좌절감, 우울증 등의 정서적인 문제를 일으키며 이차적인 학습장애를 동반한다. 이러한 발달성언어장애의 원인으로서는 사회환경적인 영향, 언어발달시기에 생긴 전도성청음장애로 인한 청각자극의 결핍, 유전적인 영향, 국소적인 뇌의 손상 등 때문으로 주장되지만 아직까지 정확한 기전은 밝혀지지 않고 있다. 이에 본 연구는 뇌전산화단층촬영이나 뇌파검사 등에는 나타나지 않는 국소적인 기질적인 병변이 존재하기 때문이라는 가설을 세우고, 뇌의 기능적인 이상을 알 수 있는 '단일광자방출전산화단층촬영'을 시행한 결과, 61.9%(26/42)에서 혈류의 감소가 있음을 발견하였다. 이상소견이 발견된 뇌의 부위가운데에서 대뇌피질이 47.6%(20/42)로서 가장 많았고, 그 다음으로는 시상부위가 33.3%(14/42)로 많았다. 이러한 결과로 미루어 볼 때 발달성언어장애가 뇌혈류의 이상소견과 관련된 뇌기능장애와 관련되어 나타날 가능성이 있음을 알 수 있었다. 향후 동일한 대상 환아군들을 추적 조사하여 증상이 호전된 후에 다시 단일광자방출전산화단층촬영을 실시하여 본 연구결과와 비교연구를 시행한다면 보다 정확한 원인 규명이 가능할 것으로 판단된다.

The Fontan operation is a heart operation used to treat complex congenital heart defects like tricuspid atresia, hypoplastic left heart syndrome, pulmonary atresia and single ventricle. A single ventricle is dedicated to pumping oxygenated blood to the systemic circulation and the entire systemic venous return reaches the pulmonary arterial system without the direct influence of a pumping chamber. In the patient with Fontan operation, it is important to achieve adequate pulmonary blood flow and cardiac output in anesthetic management. In this case, a 10-year-old boy (19.6 kg, 114 cm) with cleft palate, cerebral palsy and severe mental retardation, who underwent a Fontan operation when he was 4 years old, was presented for deep sedation. Because he was suffering from eating disorder with cleft palate, the orthodontist and the plastic surgeon planned to insert intraoral orthodontic device before cleft palate repair. But it was impossible to open his mouth for alginate impression procedure. After careful pre-anesthesia evaluation we planned to administer deep sedation with propofol infusion. After Intravenous catheter insertion, we started propofol intravenous infusion with the formula of a loading dose of 1.0 mg/kg followed by an infusion rate of 6.0 mg/kg/hr with syringe pump. His blood pressure was remained around 80/40 mmHg after loss of consciousness, but he could not maintain his airway patent. So we lowered the infusion rate to 3.0 mg/kg/hr, immediately. The oxygen saturation was maintained above 95% with nasal oxygen supply, and blood pressure was maintained around 100-80/60-40 mmHg. After the sedation of 110 minutes with propofol (the infusion rate to 3.0-5.0 mg/kg/hr), he fully regained consciousness, and was discharged without complication after 1 hour observation. In case of post-Fontan patient, intravenous deep sedation with propofol was safe and effective method of behavioral management during dental treatment.
