In this study, a vehicle vector using cryptic plasmids was constructed for gene transfer in Helicobacter pylori. pHP51(3.9 kb) and pHP489(1.2 kb) were selected for constructing vectors from cryptic plasmid of H. pylori isolates in Korea. The HindⅢ-digestedDNA fragment(1.2kb) of pHP489 and 1.6kb DNA fragment of pHP51 were ligated with a kanamycin resistance gene(aph3'-Ⅲ) from C. jejuni to produce the recombinant plasmids pHP489K and pHP51K, respectively. Transformation frequency of pHP51K by electroporation was low. But pHP489K could be effectively transformed into various H. pylori strains. In order to design an intermdiate vehicle vector for gene transfer into H. pylori, pBlueHP489K was prepared by recloning pHP489K DNA into pBluescript and pTZ19R vector. This vector permitted the DNA fragment containing pHP489 sequence, aph3'-Ⅲ, and cloned DNA to be cut and self-ligated in the SacⅠ site after cloning. ureA and ureB gene were inserted into pBlueHP489K, resulting in pBlueHP489K/AB. The DNA fragment containing pHP489, kanamycin resistance gene(aph3'-Ⅲ), and urease structural gene was cut away from pBlueHP489K/AB and self-ligated to generate pBlueHP489K/AB. pBlueHP489K/AB made urease-negative H. pylori strains restore their urease activity. By this experiment, pBlueHP489K was confirmed to be the vehicle system for transferring H. pylori genes.

Objectives:Hypothalamic-Pituitary-Adrenocortical(HPA) system dysregulation plays an important role in the pathophysiology of major depressive disorder. Medically unexplained somatic symptoms comprised the predominant complaints of korean patients with major depressive disorder. It might be related to dysregulation of HPA system and somatic symptoms. The aim of this study was to investigate the association between Hamilton Depression Rating Scale severity and the Plasma Adrenocorticotropic Hormone(ACTH) & Serum Cortisol level in Korean patients with major depressive disorder. Methods:Our study design was prospective. A total 111 hospitalized patients with major depressive disorder (DSM-IV) at Anam Hospital, Korea University Medical Center between Jan 2009 and May 2011 were selected. Hamilton Depression Rating Scale was measured by psychiatrist. Plasma ACTH, Serum Cortisol levels were analyzed at the time of admission. Results:There are significant correlations(p<0.05) between Hamilton Depression Rating Scale of somatic component(HAM-D 11-15 item) and Plasma ACTH and Serum Cortisol level. However, other HAM-D sub items were not significantly correlated with Plasma ACTH and Serum Cortisol level except somatic component. Conclusion:Our Study results suggest that hyperactivity of HPA axis might be correlation with somatic symptoms in korean patients with major depressive disorder.

Objectives : This study was designed to evaluate relation between 6 weeks pharmacotherapy and the alteration of autonomic nervous system in patient with panic disorder. Methods : The subjects were patients (n=44) who met DSM-IV criteha for panic disorder with or without agoraphobia. They were measured Anxiety Disorder Inventory Schedule-Panic attack & agoraphobia (ADIS-P & A), Clinical Global Impression (CGI) Hamilton Rating Scale for depression (HAM-D), Panic Disorder Severity Scale (PDSS) and heart rate Vahability (HRV) before and after 6 weeks pharmacotherapy. We prescribed paroxetine primahly and benzodiazepine (clonazepam, alprazolam) in case needed. For analysis, we performed paired sample t-test, partial correlation, stepwise multiple regression. Results : After 6 weeks pharmacotherapy, a assessed clinical inventories significant improved. In HRV, patients showed stabilized sympathetic activity (LF, Normalized LF, 1og_LF), increased parasympathetic activity (Normalized HF). There were significant correlation between symptom improvement with parasympathetic components and symptom aggravation with sympathetic components. Multiple regression analysis showed that Normalized HF and TP were best explanatory variables of symptom improvement. Conclusion : This study suggests that 6 weeks pharmacotherapy is related to the alteration of autonomic nervous system and clinical improvement.

Purpose: This Study a descriptive correlation survey with the purpose of identifying the relationship between family function and hope in adolescents. It was done to provide basic data for developing family centered nursing strategies to promote adolescents' hope. Methods: The subjects of this study were 1030 high school students in J city. Data were analyzed with SPSS 10.0 program. Frequencies and percentages were used to compare the subjects' general characteristics. Minimum values, maximum values, mean scores and mean grades were used to identify the level of family function and hope. Pearson's correlation coefficient was used to analyze the relationship between family function and hope in adolescents, and t test, ANOVA, and Scheffe test were used to examine the level of family function and hope by general characteristics. Results: 1. The level of adolescents' family function ranged from 26 to 97, the mean score was 66.85±13.16, and the mean grade was 2.76±0.52. 2. The level of adolescents' hope ranged from 55 to 153, the mean score was 111.48±17.64 and the mean grade was 2.78±0.44. 3. It showed that there is a significantly positive correlation (r=0.546, p=.000) between adolescents' family function and hope. That is, the better family function adolescents have, the higher level of hope they have. 4. Adolescents' family function showed significant differences according to school record (F=6.363, p=.002), school life satisfaction (F=4.922, p=.007), father's education (F=2.640, p=.048), mother's education (F=3.586, p=.013) and domestic economy status(F=3.022, p=.049). 5. Adolescents' hope showed significant differences according to religion (t=2.018, p=.044), school type (t=2.567, p=.010), school record (F=9.712, p=.000), school life satisfaction (F=11.367,p=.000), father's education (F=4.632, p=.003), mother's education (F=4.709, p=.003), domestic economy status (F=4.235, p=.015), relationship with friends (F=8.187, p=.000), and subjective health condition (F=5.490, p=.001). Conclusion: First, in order to improve adolescents' family function, which encourages hope in adolescents, it is necessary to develop nursing interventions and to make further studies. Second, it is necessary to develop instruments for improving Korean adolescents' family function and hope. Third, further studies are required to improve adolescents' family function and hope in special situations such as disease, drug abuse and juvenile delinquent.

Objective : We analyzed and investigated clinical manifestations, laboratory tests, and inhibitor development of hemophilia that had not been thoroughly studied. Methods : We retrospectively reviewed 96 patients with hemophilia who were registered in the Hanyang University hospital from Jan, 1984 to Dec, 2003, Results : The total patients, whose median age at onset was 46.0 months, in clude 84 cases of type A (87.5%) and 12 cases of type B (12.5%). The most common chief complaint was a traumatic hemorrhage. The family histories of hemophilia were revealed in 41 cases (42.7%). The median activated partial thromboplastin time (aPTT) was 66.7 seconds. The number of severe cases was 39 (40.6%). Inhibitors were present in 13 cases (13.5%) and seven cases (53.8%) were high responders. aPTT and factor levels showed reverse correlation (r=-0.467). aPTT is more prolonged in group without family history than the group with family history (P=0.037). Conclusion : In this study, the diagnosis of hemophilia are made at the lower age and the serological positivity of the HCV is decreased. Activated partial thromboplastin time and factor levels shows reverse correlation. Activated partial thromboplastin time is more prolonged in group without family history compared with group with family history. The frequencies of family history are lower than those of other developed countries, because of concealing the family history of hemophilia. The prevalence of the development of inhibitors increased compared with those of previous studies in Korea, but was lower than those of other countries. Further studies would be necessary to decrease the inhibitor development.

Objective : nvasiveness of squamous cell carcinoma in oral cavity is associated with poor prognosis, and MMPs have an important role in degradation of extracellular matrix and bawement membrane of vessil walls. Increased expressions of MMPs is related to infiltrative growth and lymph node metastases in human cancers. In normal tissue, there is balanced secretions of MMPs and TIMPs, but impaired balance of MMPs and TIMPs was noted in cancer tissue. The aim of this study is to evaluate the expression rates of MMP-1, 2, 3 and TIMP 1 and 2 in squamous cell carcinoma of the oral cavity, and relationship between MMPs and TIMPs expression and histologic grade and invasion pattern. Methods and Material : Pathologic review of fifty cases of squamous cell carcinoma during a period of Mar. 1994 to Feb. 2000 based on histologic grade and invasion pattim and immunohistochemical stains for MMP-1, 2, 3 and 9 and TIMP-1, 2 were done. Statistical analysis between MMPs and TIMP s expression rate and pathologic parameters and relationship between MMPs and TIMPs were performed. Results : Expression rates of MMP-1, 2, 3 and 9were 32.0%, 38.0%, 22.0% and 20.0%, respectively. MMP-2 expression rate was higher in well differentiated carcinomas and in cases with less-infiltrative pattern. Other MMPs show slightly higher expression rate in well differentiated carcinomas, but there were no statistical significances. There were no significant differences of MMP-1, 2, 3 and 9 expression rates according to invasion pattern. Expression rates of TIMP-1 and TIM-2 were 22.2% and 48.0%, respectively, and there were no significant differences according to histologic grade and invasion pattern. Significant correlations of MMP-1, 2, 3 and 9 expressions except between MMP-2 and MMP-3 were noted, but there were no significant correlations between MMPs and TIMPs expression. Conclusion : Conclusions: In well differentiated and less infiltrative squamous cell carcinomas of the oral cavity, expression rates of MMPs, especially MMP-2, were high. And there were positive correlation between MMPs, but no correlation between MMPs and TIMPs. These findings suggest that MMPs may have a role in tumor developent of a subset of squamous cell carcinoma with less aggressive behavior and MMPs may involve in early stage of tumor progression.

The flexible bronchoscopy is not frequently used in children as in adults due to many causes. However the role of bronchoscopy in children is important in respect of diagnosis and treatment. We have done with flexible bronchoscopy for the purpose of diagnosis and treatment in a two-month-old infant with pneumonia and atelectasis. The lipid-laden alveolar macrophage(LLAM) index was 227/400. We thought the aspiration pneumonia of the patient resulted from his mother's abnormal feeding posture. After the bronchoscopy and washing, the radiologic findings and clinical symptoms were improved. We recommended the feeding position to the patient's mother and he has been well-being state afterwards.
