The population of Ralstonia solanacearum (Rs) in soil is very important as a primary inoculum source of bacterial wilt in tobacco fields. To investigate the population of Rs, physical properties and chemical components during the tobacco growing season, soil samples were taken from the fifteen fields which were located in the flue-cured tobacco growing area, Ansung, Kyunggi province and Wonju, Kangwon province. Two fields of the fifteen were bacterial wilt free. Six fields had less than 10% plants being diseased and seven over 10%. The Rs population level determined by using SMSA medium generally showed an up-and-down pattern being low in May, high in Jun and July and low in August. The soil population in May and June showed a positive correlation with the incidence of bacterial wilt (r=0.571$^*$, r=0.688$^{**}$), but P$_2O_5$, content of soil was negatively correlated with the disease incidence (r=-0.539$^*$). These results suggest that Rs population in soil examined in May or in June, and the P$_2O_5$ content in soil should be key factors to determine the bacterial wilt potential of tobacco fields.

Accurate identification of pine wood nematode, Bursaphelenchus xylophilus is a prerequisite to diagnose the pine wilt disease. However, a fungivorous nematode, B. mucronatus is highly similar to B. xylophilus and it is difficult to differentiate these two species by morphological features. A molecular diagnosis method, ITSRFLP was applied for the identification of B. xylophilus and B. mucronatus from Korea. Genomic DNA was extracted from a single individual nematode and ITS DNA was amplified by PCR. The size of PCR product was approximately 900bp and the sequence data were obtained after cloning. Amplified ITS was digested by 5 different restriction enzymes (Rsa I, Hae III, Msp I, Hinf I, and Alu I) and provided a discriminatory profile for B. xylophilus and B. mucronatus. Besides, B. mucro- natus was determined to have 2 different genotypes, East Asian type and European type also clearly separated by Rsa I and Hae III digestion. European type of B. mucronatus is recently collected from Pinus koraiensis and has not been reported before. ITS sequnce data were analyzed by Restriction Mapper program and the result supported ITS-RFLP pattern. These data indicated that PCRRFLP method is an accurate and simple way for identification of Bursaphelenchus species.

Sj$\ddot{o}$gren's syndrome (SS) is an autoimmune disease characterized by keratoconjunctivitis sicca and xerostomia. About thirty percent of patients with Sj$\ddot{o}$gren's syndrome experience nervous system involvement such as myelopaty, optic neuropathy, and peripheral neuropathy. The most common pattern of peripheral nerve involvement is axonal polyneuropathy. We present a case of demyelinating polyneuropathy in a patient with Sj$\ddot{o}$gren's syndrome, which had been proven by electrophysiology and pathology.

Beevenom immunotherapy(BVIT) in allergic patients is a well-established treatment modality for the prevention of systemic anaphylactic reactions caused by insect stings. BVIT is accompanied by increases in allergen-specific IgG, particularly the IgG4 isotype, which blocks not only IgE-dependent histamine release from basophils but also IgE-mediated antigen presentation to T cells. Inhibition of T cells after BVIT also involves decreased induction of the costimulatory molecule ICOS, which, in turn, seems to be dependent on the presence of IL-10, also associated with the inhibited status of T cells after BVIT. Suppression of T cells by IL-10 is an active process, which depends on the expression and participation of CD28. Immune tolerance in specific allergen immunotherapy might be a consequence of decreased Th2 or increased Th1 response of allergen specific T lymphocytes. BVIT shifted cytokine responses to allergen from a TH-2 to a TH-1 dominant pattern, suggesting direct effects on T cells. Many studies showed that severe side effects due to venom immunotherapy are rare. These results suggest that immunological changes after BVIT may be applied to be therapeutic alternative of general allergic diseases including beevenom allergy.

Background: Recently, pain clinic is attracting attention and interest of both physicians and laymen. It is the purpose of this article to analyze our 10 years' experience to seek and improve better protocol of treating pain. Methods & Materials: We analyzed retrospectively 11,235 patients who visited the clinic during 10 years from 1986 to 1996. Total number of hospital visits was 51,908. Male to female ratio was 35：65(3910：7325). Treatment modalities employed were SGB(stellate ganglion block), TPI(trigger point injection), etc. Results: Yearly distribution showed a gradual upward curve until 1992 and remains in a horizontal pattern thereafter. Of age distribution, 6th decades occupied the largest proportion(27.29%). As of disease entities, Low back pain & lower extremities pain comprised of the majority(34.01%) and the epidural block was most frequently given as a treatment. Conclusion: Pain clinic is improving rapidly as an important part of medical science in Korea and outpatients of clinic are on an increasing trend. So, anesthesiologists should be make every efforts to research for treatment of good quality.

We observed yellow catfish Pelteobagrus fulvidraco fingerlings cultured in land ponds in Korea swimming in a corkscrew spiral pattern while hanging head-up and tail-down at the water surface, before eventually dying. Externally, these fish displayed “hole in the head” disease, pale gills, and hemorrhages in the base of the pectoral and caudal fins; internally they had liver hemorrhages and kidney discoloration. The bacterium Edwardsiella ictaluri (YCK-01 and YCL-01) was identified in the kidneys and livers of diseased fish via phenotypic characteristics and PCR analysis using the ictaluri-specific primers IVS (an intervening sequence) and IRS (the inter-ribosomal spacer). Infectivity challenges by intraperitoneal and immersion routes showed that a representative bacterial strain (YCK) exhibited strong virulence to yellow catfish, with an LD₅₀ of 3.2×10⁴ CFU/fish and 2.5×10⁶ CFU/mL, respectively. This is the first report of E. ictaluri infection in yellow catfish from Korea.

The following result are obtained through that comparative study on the psychotherapy of oriental and occidental medicine. 1. The shamanism(祝由) and active emotion therapy(移精變氣療法) are a primitive form of psychotherapy. It is an opinion that between active emotion therapy(移精變氣療法) and psychoanalytic therapy or supportive psychotherapy are similar. Also, the basic cognition pattern of shamanism(祝由) is projection. 2. Taoism is inseparably related to the psychotherapy of korean oriental medicine, the major thought has become the ideal base of oriental psychotherapy. 3. According to study of clinical document in relation to oriental psychotherapy, psychotherapy had been widely used by medical cure. 4. The five emotion restraint therapy is a high level psychotherapy of oriental medicine. Oriental psychotherapy that disease caused by surprising must be cure by surprising is like to systematic desensitization in western, and that pseudopsychosis must be cure by patient rely on doctor is like to suggestive therapy in western. 5. There are psychotherapy in western that Supportive psychotherapy, Short-term dynamic psychotherapy, Psychoanalytic therapy, Group psychotherapy, Family therapy, Morita therapy, Hypnotherapy, Autogenic training, Behavioral therapy, Milieu therapy, Occupational therapy, Psychodrama, the others. I think that they have wide application to the psychotherapy of korean oriental medicine.

Bronchial carcinoid tumor accounts for less than 5% of all primary lung tumors in adults. Although surgical resection is the treatment of choice, here we report a case of bronchial carcinoid tumor treated with flexible bronchoscopic resection. A 19-year-old-man presented with a history of wheezing with dyspnea for six months. A simple chest x-ray showed no abnormal findings, but a pulmonary function test showed a moderate obstructive lung disease pattern without a bronchodilator response. A computed tomogram of the thorax revealed an enhanced $15{\times}12$ mm nodule in the left main bronchus. Bronchoscopic examination showed a polypoid mass with a stalk in the left main bronchus, which almost completely occluded the left main bronchus. Histopathology of the resected specimen revealed a bronchial carcinoid tumor. We treated the carcinoid tumor with a flexible bronchoscopic resection. During the follow up period of 6 months, the previous tumor didn't relapse. Initial bronchoscopic resection should be considered when bronchial carcinoid tumor can be approached by bronchoscopy.
