The authors observed the ultrastructure of oral leukoplakia simplex of gingiva, buccal mucosa, tongue and alveolar ridge. For the purpose of clearly defining the lesions under investigation in this study, leukoplakias were cinsidered to be any white patches on the oral mucous membranes that could not be removed by rubbing and could not be classified clinically or microscopically as another diagnosable disease. The tissue to be examined were embedded in paraffin for light microscopic study. The tissue to be examined under the electronomicroscope were fixed in 2.5% glutaraldehyde in 0.1M cacodylate buffer and 1% osmic acid in 0.1M cacodylate buffer, dehydrated with guaded alchol, and treated with propylene oxide, and embedded in Epon.Ultrathin sections were obtained by LKB III ultrotome, stained with uranyl acetate/lead citrate, and examined with Corinth 500EM. The results were as follows : 1. Epithelium of leukoplakia consisted of stratum basale, stratum spinosum, stratum granulosum and stratum corneum. 2. There was hyperorthokerotosis or hyperparakeratosis. 3. Granular cells contained a lot number of membrane coating granule showing lamellar structure, clearing ot codensation, and a lot of keratohyaline granule varied in size. 4. An increased concentration of tonofilaments and an increased number of desmosomes were found in the stratum spinosum. 5. Basal lamina generally showed its continuity, but in some locatoins, its interreption and multiplication appeared.

Medial medullary infarction is caused by occlusion of vertebral artery or lower basilar artery. In this report, one case had impaired pain and thermal sense over half the body, and complained of dizziness, nausea and vomiting. The other symptoms were slippery pulse(脈滑), pale tongue with whitish coating(舌淡苔白), white face(面白), obesity(體肥) and unchanged skin color(肌色如故). We diagnosed this patient as the Gastrointestinal Phlegm(食痰) and prescribed Jengjengamiyijin-tang (Zhengchuanjiaweierchen-tang). The symptoms of impaired pain and thermal sense, dizziness, nausea, and vomiting were improved. So, we suggest that Jengjengamiyijin-tang (Zhengchuanjiaweierchen-tang) could be effective to the patient with the symptom of the Gastrointestinal Phlegm(食痰)

한의학에서 혀는 인체 내 생리, 병리적 변화를 반영하여 진단에 있어 중요한 지표자료로 사용하고 있다. 하지만 설진은 진단환경에 의한 영향을 많이 받게 되어 객관적이고 정량화된 결과를 얻기 힘들며, 그로 인해 한의사의 진단에 대한 신뢰성도 낮아 널리 활용되지 못하고 있다. 이를 해결하기 위해 본 연구에서는 제한된 측정환경을 제공하는 디지털 설진 시스템을 통해 한의사로부터 황태라 진단받은 48명과 백태라 진단받은 14명의 설 영상을 획득하고, 설태의 컬러벡터값을 구하여 백태와 황태를 구분하는데 유의한 변수를 도출하였으며, 이를 이용하여 한의사의 설태 진단과 일치율이 높은 판별함수를 도출하였다. 이와같은 연구방법은 백태, 황태 뿐 아니라 회태나 흑태 또는 후태나 박태를 구분하는 데에도 유용하게 쓰일 수 있을 것이며 앞으로 한의사의 설진과정을 객관화, 과학화하는 과정에 기여할 수 있을 것이다.

Objectives : The purpose of this study was to analyze the trend of clinical research on quantitative indicators of Mibyeong in traditional chinese medicine(TCM). Method : The journal search was performed using china national knowledge infrastructure(CNKI) database. Our inclusion criteria were as following: TCM clinical researches for quantitative indicators of Mibyeong. Exclusion criteria were as following: non-TCM clinical researches, used intervention methods. Results : Eleven clinical researches were analyzed in this study. Four of these researches classify the Mibyeong as a type of pattern identification(PI) and studied the characteristics of the PI quantitative indicators. Mibyeong diagnosis was done through guidelines and questionnaires, each was used at a similar rate. Quantitative indicators mentioned in the selected researches were blood indices, nailfold capillary, complexion, color of tongue substance and coating, pulse wave diagrams and heart rate variability. Among them, seven researches related to blood indices were the most. Blood indicators include whole-blood viscosity, plasma viscosity, fibrinogen, packed cell volume(Hct), triglycerides, total cholesterol, HDL-C, LDL-C, glucose, BUN/CREA, luteinzing hormone, estradiol, follicle stimulating hormone, IgA, IgG, etc. Conclusions : Based on this results, in combination with western medicine, it seems necessary to try to interpret the Mibyeong in more various ways. Even if the same Mibyeong, it is necessary to identify the index which changes according to the PI or chief complaint, and to set the Mibyeong standard corresponding thereto.

Purpose: Patients with taste complaints presenting with various abnormal perceptions and alterations in gustatory function are often encountered in dental clinics. Since taste perception is thought to be influenced by numerous factors including neurological and psychological factors, the gustatory profiles of patients complaining of taste abnormalities should be very different. However, the gustatory profiles based on the clinical subtypes of taste complaints have not been fully studied. This study aimed to better understand the gustatory profiles depending on the clinical subtypes of taste complaints. Methods: Clinical data from 169 patients with complaints of altered taste were retrospectively collected to analyse their clinical and gustatory profiles. These complaints were subdivided into hypergeusia, hypogeusia, and dysgeusia for each taste quality according to the clinical types of these complaints. The gustatory profiles were then established by analysing the detection and recognition thresholds for each taste quality depending on the clinical subtypes of taste complaints. Results: Clinical analysis revealed that patients with taste complaints had widely diverse clinical profiles. There were significant differences between males and females with taste complaints in the prevalence rates of symptoms like dry mouth, tongue coating, and burning sensation. While hypogeusia (76.3%) was the most frequent type of taste complaint, it was revealed that the taste thresholds were not always consistent with the patient's description of gustatory symptoms. Conclusions: Patients with taste complaints exhibited diverse clinical profiles with sex differences. Considering the diversity of the taste complaints, the quantitative gustatory testing methods can be valuable to differentially evaluate the presence and intensity of altered taste in patients with these complaints.

Purpose: The institutionalized elderly have placed the most vulnerable state, and the report about the oral health status of the institutionalized elderly was scarce. The aims of the current study were to investigate the oral health status of institutionalized elderly. Materials and methods: The survey of the oral health status was carried out on 487 institutionalized elderly from 4 longterm care facilities of Seoul metropolitan city, Gyunggi province, and Gangwon province in Korea. Results: The prevalence of dental caries, root caries, and dental calculus of the institutionalized elderly was 19.2%, 15.3%, and 23.7%, respectively. The percentage of edentulism among the institutionalized elderly was 26.2%. Those who had poor oral hygiene and tongue coating were 43.9% and 90.5%, respectively. The percentages wearing complete and removable partial denture on maxilla were 12.8% and 3.3%, respectively. The percentages wearing complete and removable partial denture on mandible were 7.8% and 5.6%, respectively. The percentages of institutionalized elderly needing complete and removable partial denture on maxilla were 29.7% and 27.2%, respectively. The percentages of institutionalized elderly needing complete and removable partial denture on mandible were 24.5% and 30.9%, respectively. Conclusion: The oral health stuatus of institutionalized elderly was poor. For the oral health promotion of elderly in longterm care facilities, it is essential to educate nurses and caregivers about the importance of the oral health and oral hygiene method.

Objectives : This study aimed to clarify the relationship between the Oriental medical diagnosis and arteriosclerosis by measuring carotid-ankle vascular index(CAVI) in acute cerebral infarction patients. Method : One hundred thirty-one subjects were recruited from the patients admitted to the Internal Medical Department at Kyunghee University Oriental Medical Center from April 2007 to August 2008. We sorted cerebral infarction patients and assessed one hundred fourteen patients' CAVI data. We diagnosed dampness-phlegm by Oriental medical diagnosis and evaluated stroke type by single or multiple infarctions. then, we analyzed their characteristics with type of stroke, risk factor, lifestyle, metabolic syndrome and dampness-phlegm diagnosis. Result : 1. On the demographic variables of the patients, age, hypertension, hyperlipidemia, multiple infarction group and metabolic syndrome and dampness-phlegm group were significantly higher in the high CAVI score group than in the control. 2. According to the significant difference in the dampness-phlegm group, we analyzed dampness-phlegm related index for pattern identifications by CAVI score. As a result, dark circles, insomnia, headache, white coating tongue. slippery pulse, and rough pulse were significantly higher in the high CAVI score group then in the control. 3. In multivariate analysis, age, hypertension, multiple infarction and dampness-phlegm groups showed a close relationship with the high CAVI score group. Conclusions : According to the analysis, significance between dampness-phlegm diagnosed patients group and high CAVI score were clarified. Moreover, multiple location infarctions also have a relationship with high CAVI score in cerebral infarction patients. These results can be utilized in the future as a basis material.
