  • Purpose: The diagnosis of chronic rhinosinusitis requires a comprehensive knowledge of the signs and symptoms of the disease and an accurate radiographic assessment. Computed tomography (CT) is the superior imaging modality for diagnosis of chronic rhinosinusitis. However, considering the lower dose and higher resolution of cone-beam computed tomography (CBCT) compared to CT, this study aimed to assess the agreement between the findings of CBCT and functional endoscopic sinus surgery (FESS). Materials and Methods: This descriptive prospective study evaluated 49 patients with treatment-resistant chronic rhinosinusitis who were candidates for FESS. Preoperative CBCT scans were obtained before patients underwent FESS. The agreement between the CBCT findings and those of FESS was determined using the kappa correlation coefficient. The frequency of anatomical variations of the paranasal sinuses was also evaluated on CBCT scans. Results: Significant agreement existed between pathological findings on CBCT scans and those of FESS, such that the kappa correlation coefficient was 1 for mucosal thickening, 0.644 for nasal deviation, 0.750 for concha bullosa, 0.918 for nasal polyp, 0.935 for ostiomeatal complex (OMC) obstruction, and 0.552 for infundibulum thickening. Furthermore, 95.9% of patients had 1 or more and 79.6% had 2 or more anatomical variations, of which nasal deviation was the most common (67.3%). Conclusion: Considering the significant agreement between the findings of CBCT and FESS for the detection of pathological changes in the paranasal sinuses, CBCT can be used prior to FESS to detect chronic rhinosinusitis and to assess anatomical variations of the OMC.

  • Objective: In the winter of 2002, severe acute respiratory syndrome(SARS) began to spread throughout the world. More than 5,000 cases were reported in China, including over 1,700 cases in Hong Kong Special Administrative Region(Hong Kong SAR). The total number of cases reported from Canada and Singapore was more than 200. The total number of SARS cases world-wide reached 8,437 with incidences in 29 counties. Mortality from SARS is estimated at $10{\sim}12%$. When the SARS outbreak occurred in China, the State Administration of Traditional Chinese Medicine of China immediately initiated clinical research projects on the use of integrated herbal medicine and Western medicine for treating SARS. and, in Hong Kong SAR, research on the use of herbal medicine for the prevention and treatment of SARS. Reports were released during convalescence. The objective of this study is to overview twelve clinical SARS reports of WHO on the treatment of SARS with herbal medicine and evaluate the efficacy and safety of treatment of SARS with herbal medicine, and further to share experiences and knowledge of the treatment of SARS. Methods: Twelve clinical reports about SARS from the WHO were selected, overviewed and evaluated for efficacy and safety of treatments of SARS. Results and Conclusion: Twelve clinical reports about SARS showed that the integrated treatment may have advantages, and the advantages are reflected in the following findings: Firstly, herbal medicine is not targeted only at a specific etiology or a certain pathological link, but also at the pathological status of the patients at that particular time. Therefore, comprehensive readjustment was made through various angles, targets and channels to restore the balance of the body. Secondly, there are advantages in the differentiation of the disease and the treatment. Based on the various symptoms, herbal medicine enables the physician to adopt the most suitable principle, provide individual treatment, and to administer medicine in accordance with the actual process and nature of the illness. Thirdly, there are advantages in the results of the treatment; herbal medicine can relieve symptoms, promote absorption of lung inflammation, improve the degree of blood oxygen saturation, regulate immunological functions, reduce the required dosage of glucocorticoid and other Western medicines, and reduce case fatality rate, in addition to lowering the cost of treatment.

  • Backgrounds : In recent years there has teen renewed interest in the importance of 8-constitution medicine as evidenced by growth of research in this field. Although diagnosis by 8-constitution depends on pulse types, it still is subjective and thus could be insignificant. Therefore, diagnosis based on objective characteristics is essential. Objectives : The purpose of this study was to find objective characteristics of the 4-constitution groups {木(Mok; hepatonia, cholecystonia), {土(To; pancreotonia, gastrotonia), {金(Gum; pulmotonia, colonotonia), {水(Soo; renotonia, vesicotonia)} in 8-constitution for further diagnosis and therapy. Also, some significant clinical tendencies of 4-constitution groups were studied. Methods : From Nov. 2001 to Apr. 2004, data were collected through a questionnaire given to 720 patients who were classified into one of 8 constitutions according to their pulse types and their responses to constitution-based acupuncture therapy. The questionnaire was composed of 80 items which were about personality, physical shape, habit, physiological and pathological symptoms, response to drugs, favorites and responses to various foods. The data were statistically analyzed by cross-tabulation and one-way analysis of variance, and SPSS V10.0.7PC was used. Results : The results are summarized as follows: 1) Among participants, proportions of hepatotonia, pancreotonia, and cholecystotonia were higher than those of vesicotonia, pulmotonia, colonotonia, renotonia, grstrotonia. 2) 52 items of 80 variances showed significant differences by gender, 3) 13 items were highly correlated with 4-constitution groups in males, and 26 items in fremales. 4) 22 items showed significant group differences among 4-constitution groups in males, and 41 items in females. Also, for each item 4-constitution groups were sorted according to their means, so that the constitutional tendencies were objectively figured out by personality, shape, habit, physiological and pathological symptoms, response to drugs, favorites and responses to foods. Conclusions : Most clinical characteristics of 4-constitution groups found in this study coincided with those from the previous ones in this fold. Thus, classifying patients into one of the 4-constitution groups based on significant objective characteristics is of great benefit to diagnosis and therapy. further study should be followed to improve proper therapy for each constitution.

  • As the representative medical scholar at the time of Geumwon(金元) Dynasty, Idongwon(李東垣) deepened and developed the meaning of the diseases on internal injuries. He also proposed the primordial Gi[原氣] and Eum-Fire[陰火] theory in the physiology and pathology. Idongwon(李東垣) defined the pathological metabolism of internal injuries as the hyperactivity against Eum-Fire[陰火] due to the lack of primordial Gi[原氣不足], and he suggested the deficiency of Gi[氣虛] in the Spleen and Stomach and the surge of seven modes of emotion as the causes of the Eum-Fire[陰火] hyperactivity. Additionally, he established the therapy principles of eliminating Heat with Sweet and Warm drug[溫熱藥] and raising yang and spreading fire[升陽散火] based upon the above mentioned pathological metabolism. The Eum-Fire[陰火] that was suggested by Idongwon(李東垣) indicates the Heat syndrome[熱證] developed by internal causes[內因], and the principle reason is the consumption of the Spleen and Stomach Therefore, it is important to recuperate the function of Spleen and Stomach in treating the disease symptoms caused by Eum-Fire[陰火], and the therapies of eliminating Heat with Sweet and Warm drug [溫熱藥] and raising yang and spreading fire[升陽散火] are the corresponding ones. However, since vital Essence could be lacked due to the consumption of Spleen and Stomach, the therapy of replenishing Eum has to be considered. Additionally, the damp removal therapeutic method also has to be considered since Damp could be stagnated by the loss of function in Spleen and Stomach. In other way, Eum-Fire[陰火] developed by the consumption of Spleen and Stomach is somewhat similar aspect to the premier Fire[相火] that is developed by the lack of Eum[陰虛]. But complications could be developed if therapies of enriching the Eum[滋陰] to suppress Fire and replenishing Eum[補陰] are mainly used to control the symptoms developed by the lack of Eum[陰虛]. Namely, the drugs used to replenish Eum[補陰] mostly have the heavy and turbid properties, which contrarily have the possibility to debilitate the functions of Spleen and Stomach by causing Dampness within a body. So, care must be made in their use.

  • Background: Multiple sclerosis (MS) and its animal model, the experimental autoimmune encephalomyelitis (EAE), are primarily characterized as dysfunction of the blood-brain barrier (BBB). Ginsenoside-Rg3-enriched Korean Red Ginseng extract (Rg3-KRGE) is known to exert neuroprotective, anti-inflammatory, and anti-oxidative effects on neurological disorders. However, effects of Rg3-KRGE in EAE remain unclear. Methods: Here, we investigated whether Rg3-KRGE may improve the symptoms and pathological features of myelin oligodendroglial glycoprotein (MOG)35-55 peptide - induced chronic EAE mice through improving the integrity of the BBB. Results: Rg3-KRGE decreased EAE score and spinal demyelination. Rg3-KRGE inhibited Evan's blue dye leakage in spinal cord, suppressed increases of adhesion molecule platelet endothelial cell adhesion molecule-1, extracellular matrix proteins fibronection, and matrix metallopeptidase-9, and prevented decreases of tight junction proteins zonula occludens-1, claudin-3, and claudin-5 in spinal cord following EAE induction. Rg3-KRGE repressed increases of proinflammatory transcripts cyclooxygenase-2, inducible nitric oxide synthase, interleukin (IL)-1 beta, IL-6, and tumor necrosis factor-alpha, but enhanced expression levels of anti-inflammatory transcripts arginase-1 and IL-10 in the spinal cord following EAE induction. Rg3-KRGE inhibited the expression of oxidative stress markers (MitoSOX and 4-hydroxynonenal), the enhancement of nicotinamide adenine dinucleotide phosphate (NADPH) oxidase 2 (NOX2) and NOX4, and NADPH activity in the spinal cord of chronic EAE mice. Furthermore, apocynin, a NOX inhibitor, mimicked beneficial effects of Rg3-KRGE in chronic EAE mice. Conclusion: Our findings suggest that Rg3-KRGE might alleviate behavioral symptoms and pathological features of MS by improving BBB integrity through modulation of NOX2/4 expression.

  • This study has been carried out to investigate the cause, pathological mechanism and treatment of symptoms regarded as the ischemic heart disease in Nei-jing(內經). I've got the following conclusions. 1. From the side of xing-bi(胸痺), the ischemic heart disease(IHD) was caused by that the energy in one's heart wasn't extended in the way of Yin-xie(飮邪), namely waste matter of human body and symptoms and treatment wern't written. 2. From the side of xin-bi (心痺), HID was catched by the mechanisms that the blood vessel is blocked. or the heart's blood was deficient owing to the mutation of mo-bi(脈痺), the lack of yang-ming(陽明) and excessive thoughts and worry and others. The symptoms were feeling oppressed in one's brest, palpitating, sudden dyspnea, the dryness of thorat, frequent belching and the fear by the inverse flow of the energy(氣). The treatment was that the yin(陰) was cured immediately, but the yang(陽) mustn't be attacked. 3. From the side of xing-tong(心痛), IHD was suffered from by mechanisms that following the han-sa(寒邪), namely the cold makes a invasion on humanbody, the vessel was blocked, spasm, filled and the amount of blood flow was poor, or caused by injury of vessel, the inverse flow and the disease of shi-dong(是動病) of shou-shao-xin-jing(手少陰心經) and so on. The pain was cramped into the upper and lower back or lower abdomen or throat and accompanied with nausea, abdominal dropsy, constipation, the impending of breathing and so on. The cure was mainly that acupuncture was applied at the jin-su(筋縮) region or meridian in relation to symptoms, but if the pain were severe, acupuncture mustn't be applied. The prog nosis was worse. 4. From the side of xing-tonge(心痛), IHD was divided into zhen-xing-tong(眞心痛) and jue-xing-tong(厥心痛), but pi-xiog-tong(脾心痛) and wei-xing-tong(胃心痛) out of jue-xing-tong(厥心痛) also included the symptoms of the digestive disease.

  • 영화 <살인마 잭의 집 The House that Jack Built>은 주인공 잭이 12년간의 연쇄살인과정에서 점차 정신병 증상을 지닌 '광기의 예술가'로 재탄생되는 모습을 다룬다. 강박증 증상을 지니고 있는 엔지니어 잭은 한차 레의 우연한 살인으로 향락을 느끼면서 사람을 죽이는 것을 하나의 예술 형태로 간주하고 이 과정에서 강박증을 극복하게 된다. 본고에서 주목하는 문제는 과연 반복 살인이라는 행위로 강박증 증상이 극복될 수 있는가? 하는 질문이다. 따라서 본고는 잭의 강박증은 살인과정에서 극복 된 것이 아니라 신경증에서 안정화 된 정신병 상태로 이행하면서 그 증상이 사라졌다는 관점을 밝히는 것이다. 프랑스의 유명한 정신분석학자 라캉(Lacan)의 이론에 따르면 인간 주체가 현실적인 안정성을 잃을 때 경험하는 환각이나 망상은 상징계의 틈새로 비집고 들어오는 실재(The Real)와 직면할 때 나타나는 현상이다. 영화 속 잭의 망상으로 구축된 가짜현실과 같은 현상은 잭에게 부성은유의 부재로 인해 '아버지의 이름'(The Name-of-the- Father)이 제대로 자리 잡지 못한 원인으로 나타나는 병리적 증상이다. 따라서 본고는 라스 폰 트리에( Lars von Trier) 감독의 영화 <살인마 잭의 집>의 주인공 잭이 지닌 정신병 구조를 라캉의 정신분석을 통해 해독한다.

  • Alzheimer's disease (AD) is a neurodegenerative disorder associated with progressive memory loss and neuronal cell death. Although numerous previous studies have been focused on disease progression or reverse pathological symptoms, therapeutic strategies for AD are limited. Alternatively, the identification of traditional herbal medicines or their active compounds has received much attention. The aims of the present study were to characterize the ameliorating effects of spinosin, a C-glucosylflavone isolated from Zizyphus jujuba var. spinosa, on memory impairment or the pathological changes induced through amyloid-${\beta}_{1-42}$ oligomer ($A{\beta}O$) in mice. Memory impairment was induced by intracerebroventricular injection of $A{\beta}O$ ($50{\mu}M$) and spinosin (5, 10, and 20 mg/kg) was administered for 7 days. In the behavioral tasks, the subchronic administration of spinosin (20 mg/kg, p.o.) significantly ameliorated $A{\beta}O$-induced cognitive impairment in the passive avoidance task or the Y-maze task. To identify the effects of spinosin on the pathological changes induced through $A{\beta}O$, immunohistochemistry and Western blot analyses were performed. Spinosin treatment also reduced the number of activated microglia and astrocytes observed after $A{\beta}O$ injection. In addition, spinosin rescued the $A{\beta}O$-induced decrease in choline acetyltransferase expression levels. These results suggest that spinosin ameliorated memory impairment induced through $A{\beta}O$, and these effects were regulated, in part, through neuroprotective activity via the anti-inflammatory effects of spinosin. Therefore, spinosin might be a useful agent against the amyloid ${\beta}$ protein-induced cognitive dysfunction observed in AD patients.
