There has been considerable controversies in the method of the treatment of dislocation of the acromioclavicular joint, especially in grade III injury. It is hard to give a direct firm repair having a short ruptured coracoclavicular ligament. Thats why there are lots of difficulties in the treatment. Therefore, in operative treatment, the authors make use of cotton tape on coracoid process and clavicle as a reconstructive technique, because we have thought a simple fixation of acromioclavicular joint adding to a firm fixation of clavicle and coracoid process is inevitable. From January 1991 to December 1995, twenty-nine cases of grade III acromio-clavicular dislocation were treated by the modified Phemister method with using the cotton tape. Twenty-four patients were followed for an average of fifteen months and the following results were obtained. 1. The clinical results were evaluated by Weitzman criteria after average fifteen months follow up. An excellent result was obtained in 19 cases (79.2%), a good result in 3 cases (12.5%) and a fair result in 2 cases (8.3%), consecutively. 2. Clinical result in patients over 60-year old were bad. 3. The comparison of the coracoclavicular interval ratio before surgery with that after surgery facilitated the evaluation of effectiveness of the coracoclavicular ligament reconstruction. 4. The operative technique is through temporary fixation using K-wires which endows horizontal stability, and it fixes clavicle and coracoid process using cotton tape which endows vertical stability.

The pleckstrin homology (PH) domain is a protein module of approximately 100 amino acids, that has been found in signaling molecules, including serinelthreonine kinase, GTPase-activating protein, phospholipase, and some cytoskeletal proteins. Although the specific function of PH domain has not been defined yet, it is believed that this domain is involved in the regulation of signal transduction pathway. The expression plasmids of human PLCg PH domains were constructed to see the roles of them in IL-6 signal transduction. When these expression plasmids are transfected into B9 cells, only N-terminal of PH domain inhibited IL-6-induced B9 cell proliferation. These results suggest that N-terminal of PH domain is critical for IL-6 signal transduction in B9 cells. To search the binding proteins associated PH domains of PLCy1 in B9 cells, Glutathione S-trnaferase (GST) fusion proteins containg PH domains were expressed in E. coli. Then, IL-6-dependent B9 cells were treated with 10 unit/ml IL-6 and the cell lysates were immunoprecipited with GST-PH doman fusion proteins. In vitro kinase assay of immune complex demonstrated that p38 (38 KDa) protein was coprecipitated with NC fusion protein, but IL-6 had no additional effect on it. When S-methaionine labelled cell lysates were used for immunoprecipitation, the same result was observed, conforming the association of p38 with NC motive of PH domain.

This article summarizes the era from when Paul Broca had first introduced his aphasia case study and theory in 1861 to clinical-neuroanatomical approach which was widely known until early twentieth century. The article also comprises the cognitive-neuropsychological approach which appeared after the cognitive revolution in 1956. It investigated and compared the definition, classification method and the primary research object of aphasia in the perspectives of clinical-neuroanatomical approach and cognitive-neuropsychological approach. Each approach has its own advantages and disadvantages. Therefore, it is inappropriate to only support for a certain approach but better if two approaches are incorporated together and used effectively in certain situations. In order for the best research and treatment for the aphasic patients, clinical practitioners who prefer clinical-neuroanotomical approach and researchers who prefer cognitive-neuropsychological approach should participate together to incorporate the two approaches.

PURPOSE: We analyzed the gene status of p16INK4A, p15INK4B and MTAP (methylthio adenosine phophorylase) in Korean hepatdegrees Cellular carcinoma (HCC) to investigate whether the inactivation of these genes participated in hepatdegrees Carcinogenesis, and evaluated MTAP-targeted chemotherapy in MTAP-deficient cell lines. MATERIAL AND METHODS: We examined eleven primary HCC and 8 SNU cell lines using PCR, Southern blot analysis, PCR-SSCP, DNA sequencing, methylation-specific PCR, Western blot analysis, MTT assay, and crystal violet staining. RESULTS: Mutations or deletion of the p16INK4A, 15INK4B, and MTAP genes were rare, but methylation of the p16INK4A promoter region was common in HCC. The base alterations of 3' untranslated region of p16INK4A exon 3 were also detected in 3 samples. In SNU cells, p16INK4A was not detectable, when treated with demethylating agent, high levels of re-expressed p16INK4A protein were detected. In MTAP-targeted chemotherapy experiment, methylthioadeno sine (MTA) was able to rescue MTAP positive cell lines but not MTAP negative cell lines from growth inhibition by depletion of methionine and MTX treatment. CONCLUSION: These results suggest that de novo methylation of the p16INK4A promoter region seems to play an important role in the pathogenesis of HCC. And treatment of MTX, combined with methionine depletion in the presence of MTA, may be a high selective treatment for MTAP negative HCC.

PURPOSE: In spite of the development of asthma management guidelines, there are discrepancies between the guidelines and real management. We surveyed the insights and the real management of asthma to assess the current status of its management in Korea. METHODS: The objects of the survey were 266 parents with asthmatic children, who attended an educational lecture by the Korean World Asthma Day Project Office (KWADPO). Face to face interviews with questionnaires of 11 questions about understanding of asthma maintenance therapy, actual conditions of taking medicine and the impact of asthma on the family life were undertaken. RESULTS: The Median age of the patients was 5.2 years old and their parents' age ranged from those in their twenties to those in their forties. The number of the patients actually taking asthma maintenance medicine (40.6 percent) was a little bit lower than the level of awareness (53.0 percent). As a controller, patients are using short-acting beta2 inhalers (35.3 percent), steroid inhalers (including combination inhaler) (31.6 percent), leukotriene receptor antagonists (24.8 percent), antihistamines (25.6 percent), theophylline (2.3 percent), etc. Regular visits to hospital or clinic were done in 53.0 percent of the patients. As a controllers, oral medications (69.2 percent) was preferred to inhalers (18.0 percent) due to better compliance and easier dosage adjustment. CONCLUSION: According to the survey, asthma had negative effects on the life quality of patients and their families. Remarkable discrepancies were noticed between the guidelines and the real-world status of taking medicine in asthmatic children. It is necessary to have patients participate actively in making asthma management plans to raise their efficacy.

PURPOSE: It is widely known that allergic diseases progress through an allergic march. However, there have not been any recent reports in Korea on how the diseases progress. METHODS: Parents who visited one of the Pediatric Allergy Clinics of four university hospitals in Seoul with a child under the age of 6 years during the period from May 1-30, 2006 were asked to complete a questionnaire. RESULTS: A total of 229 parents answered the questionnaire about their children, of which 122 were male and 107 were female. The most common allergic disease before 2 years of age was atopic dermatitis (79%). Meanwhile, in 2- to 4-year age group, allergic rhinitis (38%) and asthma (37%) were predominant. The most common allergic disease in the 4- to 6-year age group was asthma (72%), followed by allergic rhinitis (64%). Seventy-three percent of the children had a family history of allergic disease, most often in the fathers (39%). Among patients with allergic rhinitis, 50% had experienced asthma in their earlier days and 30% had experienced atopic dermatitis. In addition, 57% of the children with asthma had suffered from atopic dermatitis. Parents believed that asthma was the most serious allergic disease. CONCLUSION: In the present study, allergic disease showed a tendency to march from atopic dermatitis to asthma and then to allergic rhinitis. Early diagnosis and treatment of atopic dermatitis is, therefore, considered important for prevention of the allergic march.

Spinal dural arteriovenous fistulas are rare abnormal connections of arteries and veins on the surface of the dura. A male presenting with myelopathy, which had a slowly progressive course for about 28 months, was diagnosed by magnetic resonance imaging and selective angiography. After surgical coagulation and excision, his symptoms were mildly improved. We report here on a man who underwent a surgical procedure for his myelopathy that was due to spinal arteriovenous fistula. Although it is unusual, spinal arteriovenous fistula should be considered when making a differential diagnosis of myelopathy.
