ABSTRACT
We examined whether the abnormal EEG state by NMDA receptor blocker MK-801 can be reversed by typical and atypical antipsychotics differentially by comparing their spectral profiles after drug treatment in rats. The spectral profiles produced by typical antipsychotics chlorpromazine (5 mg/kg, i.p.) and haloperidol (0.5 mg/kg, i.p.) were differ from that by atypical antipsychotic clozapine (5 mg/kg, i.p.) in the rats treated with or without MK-801 treatment (0.2 mg/kg, i.p.) which produce behavioral abnormalities like hyperlocomotion and stereotypy. The dissimilarity between the states produced by antipsychotics and the control state was examined with the distance of the location of the canonical variables calculated by stepwise discriminant analysis with the relative band powers as input variables. Although clozapine produced more different state from normal state than typical antipsychotics, clozapine could reverse the abnormal schizophrenic state induced by MK-801 to the state closer to the normal state than the typical antipsychotics. The results suggest that atypical anesthetic can reverse the abnormal schizophrenic state with negative symptom to the normal state better than typical antipsychotic. The results indicate that the multivariate discriminant analysis using the spectral parameters can help differentiate the antipsychotics with different actions.

In Korea the system of medical management has been bifurcated into two parts since the restoration of nation from Japanese after World War II. One is 'Western Medicine' and the other is 'Oriental Medicine' like Chinese but not like Japanese. The authors attempted to study on the unification of both medicines to prevent the confusion of medicare for people. The major part of medical care is accomplished by Western medicine among people in Korea and China. However, Oriental medicine is still present as well as college of Oriental medicine in small number. There have been long struggles between two parts of medicine because of each assertions for the theories. The ancient medicine has been likely to have its characteristics either in Western or Oriental medicine although in many countries were succeeded by Western medicine except a few Asian countries such as Korea and China. In Japan since the license of Oriental(herb) medicine was ceased about one hundred years ago, the Western medicine has been authorized by law until today and the herb is the secondary medicine as a kind of folk treatment as well as continuous and enormous study for scientification. In only China and Korea this herb medicine has been kept to use as a part of medicine by law though China has developed combined medicine to use both Western and Oriental medicine by one physician since previous prime minister Chou En-Lai around the year 1950 who made a recommendation to the two medical societies, Western and Oriental. This fact has a big sense to establish the unification of two medicines in near future in Korea as well as China. For this accomplishment of medical unification both parts of medicine require sincere and enormous efforts to study the theory and practice of herb medicine even from now on. This unification of two medicines will provide the best medicare in most convenient way to the people in the world creating new world medicine like the third medicine including alternative medicine. The acupuncture is changing to a new method in Western medicine especially applying into anesthesia and pain clinic in even USA and Western countries at this time. In conclusion the unification of the Western and Oriental medicine will provide the most reasonable and practical medicare including alternative medicine to people in the world. Because the Oriental medicine will be used at least separately to supplement the Western medicine by one physician

ABSTRACT
BACKGROUND: Although the precise pathogenesis of the Behçet's disease is not yet undertween the severity of Behçet's disease and the serum cytokine level. development of cytokine research has made it possible to find out if there is an association between the severity of Behçet's syndrome and the serum cytokine level. OBJECTIVE: Our purpose was to elucidate whether the immunopathological mechanism is associated with the serum tumor necrosis factor (TNF) and interleukin-1β (I1,1β) which are predominantly produced by monocytes/macrophages, and mterleukm-6 (IL-6). METHOD: Sixty seven patients of Behçet's disease and ten healthy adults as a control group were studied. Serum TNF and IL-6 levels were detected by enzyme immunoassay and serum IL-lβ levels by radioimmunoassay. RESULTS: There were no statistically significant differences in the serum levels of TNF, IL-1β, TL-6 compared with the control group. CONCLUSION: These data suggest that the immunopathological reactions of the Behçet's disease are not associated with a monocyte/macrophage dependent mechanism, possibly due to other immunocompetent cells.

BACKGROUND: Neopterin is released from monocytes/macrophages specifically by stimulation with interferon-γ. Therefore the increase refers to the activation of T lymphocytes. OBJECTIVE: Our objective was to examine the potential role of neopterin in the cell mediated immune response to Behçet's disease. METHODS: We studied 67 patients of Behçet's disease classified by Shimizu and a control group of 30 normal healthy people. Serum neopterin was detected by radioimmunoassay technique. RESULTS: The serum neopterin concentration of the group with Behçet's disease was significantly elevated, compared with the control group (6.36 nmol/ml vs 3.63 nmol/ml). The increase of neopterin concentration was well correlated to the clinical severity of the diseases in increasing order. CONCLUSION: Our data suggest that the T lymphocyte derived IFN-γ which stimulates the production of neopterin has some role in the pathogenesis and clinical severity of Behçet's disease.

BACKGROUND: Interleukin-2 receptor (IL-2) is expressed and released predominantly activated T lymphocyte. Increased serum levels of soluble IL-2R have been noted in a variety of autoimmune diseases and in conditions associated with T lymphocyte activation. OBJECTIVE: We aimed to examine whether the T lymphocyte activation has any association with the pathogenesis of Behçet's disease. METHOD: We have measured the serum level of soluble IL-2R in serum samples obtained from 67 patients with Behçet's disease and 30 healthy people as a control group, using a double-antibody sandwich enzyme-linked immunosorbent assay technique. RESULTS: Serum soluble IL-2R levels were found to be significantly elevated in the group of Behçet's disease as compared with the control group. No significant differences were found within clinical subtypes of Behçet's disease. CONCLUSION: These findings suggest the presence of an ongoing T lymphocyte activation in this disease process.

Recent studies suggest that apolipoproteins may be better predictor of ischemic heart disease than are plasma lipids, such as total cholesterol and high density lipoprotein cholesterol(HDL-C). To examine this hypothesis, plasma levels of major lipids and major apolipo-proteins were measured and their derivatives were calculated in 30 male patients with ischemic heart disease(16 angina pectoris and 14 old myocardial infarction) and 30 age-matched male healthy controls. Plasma levels of lipids were obtained by conventional methods and apolipoproteins by Rocket immunoelectrophoresis. Levels of HDL-C, HDL2-cholesterol(HDL2-C), and apolipoprotein-AII, and ratios of HDL-C/total cholesterol, HDL2-C/total cholesterol, and apolipoprotein-AI/apolipoprotein-B were lower in the group of patients than in controls. Levels of low density lipoprotein cholesterol(LDL-C) and apolipoprotein-B, and ratios of lDL-C/HDL-C and apolipoprotein-AI/apolipoprotein-AII were higher in the group of patients. There were no statistically significant differences in the levels of total cholesterol and apolipoprotein-AI between the two groups. Stepwise discriminators analysis showed that apolipoprotein-B and apolipoprotein-AII were better discriminators than plasma lipids for identifying those with ischemic heart disease. One could correctly classify 78% of the cases by using the levels of the two apolipoproteins. By using the level of apolipoprotein-B, one could correctly classify 73% of the cases. There were no correlations between the levels of total cholesterol and HDL-C in the controls whereas there were positive correlations between the levels in the group of patients. In conclusion, this study showed that apolipoprotein-B was the best single discriminator for identifying the patients with ischemic heart disease, followed by apolipoprotein-AII.

To investigate the difference of dry ear wax and wet ear wax, the lipid composition of wet ear wax was analyzed and compared with that of dry ear wax. In dry ear wax, squalene, steryl esters, wax esters, triglycerides free fatty acids and cholesterol were found. Squalene, triglycerides, free fatty acids and cholesterol formed the main demonstrable fractions in wet ear wax. In addition, three unidentified spots were always present in wet ear wax. Our results indicate that wet ear wax is due to the difference of quantity and composition of ear wax lipids.

Testicular involvement in male patients with leprosy is well documented and may be associated with impotence, sterility and gynecomastia. Testicular histology shows atrophy of the seminiferous tubules with hypertropy and clumping of Leydig cells and hyalinization of the small and medium sized vessels. The hormonal functions of the testes have been studied by a number of workers, usually in patients with testicular atrophy and gynecomastia. In these particular patients, androgens are generally diminished while gonadotropins are increased. The pathogenesis of testicular damage is uncertain, though Wall and Wright(1974) found that testicular germinal cell antibodies were present in 75% of lepromatous, and postulated that :autoirnmunity, Erythema Nodosum Leprosum imrnune complex damage and direct invasion by Mycobacterium leprae may all be contributory.

A study was conducted on T-cell function, utilizing active & total T-lymphocyte count according to Minowata method, and B-cell function, using irrgnunoe4ctrophoresjp. Total 41 children (10 with nephrotic syadrome, 26 with meningitides, & 5 with frequent pneumonia) were entered into study group, all of them were admitted to our pediatric department during 11 months period from November, 1978 to September, 1979, As control, 22 healthy children were chosen, divided into various age groups. Following results were obtained: 1. T-cell count on normal children (total 59.4+/-0. 6, active 27.2+/-0.9%) were slightly less than that of normal adult (total 68. 2+/-0. 8, active 33. 0+/-1.9%), P value being<0.01. 2. In most cases of severe tuberculous meningitis (stage III), active T-cell count was severely depressed. However, changes of immunoglobulin & T-cell count in the other meningitides & frequent pneumonia patients were variable & inconsistant. 3. In nephrotic syndrome patients, total T-cell count was decreased in 50%, active T-cell count in 70%, and serum immunoglobulin was also decreased in 90% (9 out of 10 patients).

A case of a clinical syndrome of selective hereditary complete IgA deficiency with partial T-lymphocyte inactivation is reported. A 14 year old boy was admitted with chjef complaint of persistent wide shallow ulcerated non-vesicular patches on the skin folds of whole body, chronic upper respiatory infections and gastointestinal upsets. General appearance showed us as if the undemourished or malabsorption status had been accompanied. The duration of illness was about 10 years under the incorrect or mistaken diagnosis and skin lesions have incompletely responded to the treatment. Peripheral T-lymphocyte determination was carried out by the method of Wybran to be tumed out active T-cell 14%, total T-cell 48%. Tuberculin test showed negative with 5 TU. Immunoglobulin values were respectively as follows: IgG 325 mg%, IgM 60 mg%, and IgA trace. And we diagnosed this case as selective IgA defiency with partial T-lymphocyte inactivation. We started the immunochemotherapy with tuberculo-protein complex, Tubercin-3 and antibictics for 2 months. After 2 months with above regimen. the skin lesions were markedly improved. T-cell count also retumed to the normal limit(active 35%, total 59%) and levels of TgG and IgM raised(IgG 617.5 mg%, IgM 75mg%), but IgA still showed trace amount, Tuberculin test tumed out positive.

Cardiac arrest is the most serious complication during anesthesia and surgery. Once cardiac arrest is diagnosed, whether the heart is in standstill or in ventricullar fibrillation and whatever is the initial cause, the immediate treatment must be aimed at providing an artificial circulation of oxygenated blood to the vital organs. Authors have experienced cardiac arrest due to ventricular fibrillation during general anesthesia with hypotensive technique. When the diagnosis was established, immediate closed chest cardiac massage was carried out with drug therapy and D.C. defibrillator. Cardiac rhythm was restored immediately after the 100 joules of electric shock was given. The duration of closed chest cardiac massage was 18 minutes. The patient recovered completely without complications.

Three cases of leprosy were successfully treated with a tuberculo-protein complex, Tubercin-3, which was prepared from Mycobacterium tuberculosis by Chung( J. Korean Med. Ass. 17:427-431, 1974) and no noticeable side effects were observed. The three cases were brought to us without leprosy medication since their disease was recently diagnosed. Daily inoculations of Tubercin-3, 1.0 microgram on the forearm, subcutaneously for 8 months in Case 1, 7 months in Case 2, and 6 months in Case 3, cleared them of their lepromatous lesions.

Tracheostomy is done to treat the acute upper airway obstruction. But when the condition. precipitating tracheotomy has resolved, the tracheal cannula cannot be removed sometimes because of the anatomical change at the tracheotomised tissue. This is described that decannulation is delayed. Delayed decannulation is uncommon but occurs more frequently in young children than in adults. The child who is difficult to decannulate is continuously at risk. His family experiences emotional, social and sometimes economic hardships. Many factors may delay decannulation; a frequent cause is posterior displacement of the: anterior tracheal well above the tracheotomy stoma induced by the position and pressure of the tracheotomy cannula itself. High tracheotomy, subglottic edema, emotional dependence increase of upper air-way resistance and delayed laryngeal development are solo the factors. One of the treatment of the difficult decannulation, T-tube stent was inserted through tracheoplasty. in this report, a 24 months old girl, nasotracheal intubation was used in the attempted decannulation. Radiological and endoscopic evaluation indicated that posterior displacement of the anterior tracheal well above the tracheal stoma was the cause of the delay. Dacalnnulation was achieved after 10 days of the intubation therapy. Etiology of the tracheal stenosis, pattern of respiratory difficulty, technic and patient care of nasotracheal intubation as the therapy of delayed decannulation and the role of anesthesiologists and pediatric intensive care was discussed.
