The prevalence of right-sided infective endocarditis is increasing with a growing number of intravenous drug abusers. A case of right-sided endocarditis is reported in a 18-year-old female heroin addict. Tricuspid valve vegetation, septic pulmonary emboli and staphyloccus aureus in blood cultures are noted. During antimicrobial therapy, she developed remittent fever and skin rash due to vancomycin. After a change of the antibiotic to teicoplanin, she was freed from fever and discharged in an improved condition.

PURPOSE: Single-port laparoscopic surgery is a rapidly advancing technique in laparoscopic surgery. However, there is currently limited evidence on the learning curve for this procedure. The aim of this study was to estimate the number of single port laparoscopic cholecystectomies required until improvement in the performance of the technique ceases. METHODS: This is a descriptive, single-center study using routinely collected clinical data from 70 patients who underwent single port laparoscopic cholecystectomy between May 2009 and June 2010 at Dong-A University Medical Center in Busan, Korea. The review includes the mean operating time, conversion cases, intra-operative GB perforation, post-operative wound infection and mean hospital stay. RESULTS: The mean operating time of the first 30 cases (the learning period) was 91.83 minutes. After 30 operations (the experience period), it plateaued to an average of 75.25 minutes, which remained steady in the next 40 operations - a reduction of more than 16%. Reduction in the operating time was significant (P<0.001) between the learning period and the experience period. Other factors including additional ports, intraoperative gall bladder perforation, mean hospital stay, post-operative wound infection were not significantly different between the two periods. CONCLUSION: We suggest that the learning curve for single port laparoscopic cholecystectomy should be around thirty cases for a surgeon with prior conventional laparoscopic cholecystectomy experience and for self-taught single port technique.

The purpose of this study is to present an actual example for procedures for developing a PBL package based on philosophical backgrounds derived from Problem-based learning. To perform a systemic study on the operations of an intergrated curricula under multi-disciplines, a research team made up of several professors with different academic backgrounds was formed. Among the four situations for the patients with perception-adjustment disorder, especially a procedure for the development of PBL package which can be used in the emergency room situation has been proposed. The little(2000)'s PBL package model has been applied for this study. Tha package includes course objectives, learning objectives, concept map, situation scenario, tutor guide, and evaluation method. It is believed that learning objectives achievement procedures designed as a part of a problem-based learning package development procedures for the nursing of patients with perception-adjustment can be achieved at the same level as the learning objectives for the science of nursing founded by the Korean Nurses Association.

Oligodendroglioma that occurs in the ventricle has been reported uncommonly. The case is reported of a 38-year-old man who presented with severe headache and vomiting and was discovered to have an oligodendroglioma in the lateral and third ventricles. The clinical presentation, radiological finding, pathology and response to radiation are described with brief review of general biology in oligodendroglioma.

Myristoylated alanine-rich C kinase substrate (MARCKS) is a widely distributed protein kinase C (PKC) substrate and has been implicated in actin cytoskeletal rearrangement in response to extracellular stimuli. Although MARCKS was extensively examined in various cell culture systems, the physiological function of MARCKS in the central nervous system has not been clearly understood. We investigated alterations of cellular distribution and phosphorylation of MARCKS in the hippocampus following kainic acid (KA)-induced seizures. KA (25 mg/kg, i.p.) was administered to eight to nine week-old C57BL/6 mice. Behavioral seizure activity was observed for 2 h after the onset of seizures and was terminated with diazepam (8 mg/kg, i.p.). The animals were sacrificed and analyzed at various points in time after the initiation of seizure activity. Using double-labeling immunofluorescence analysis, we demonstrated that the expression and phosphorylation of MARCKS was dramatically upregulated specifically in microglial cells after KA-induced seizures, but not in other types of glial cells. PKC alpha, beta I, beta II and delta, from various PKC isoforms examined, also were markedly upregulated, specifically in microglial cells. Moreover, immunoreactivities of phosphorylated MARCKS were co-localized in the activated microglia with those of the above isoforms of PKC. Taken together, our in vivo data suggest that MARCKS is closely linked to microglial activation processes, which are important in pathological conditions, such as neuroinflammation and neurodegeneration.

The aim of this study was to investigate antimicrobial effect of oleanolic acid (OA), ursolic acid (UA), and sophoraflavanone G against Enterococcus faecalis and Propionibacterium acnes, which are the major causative bacteria of endodontic infections. The antimicrobial activity was evaluated by the minimal inhibitory concentration (MIC). The data showed that the OA, UA, and sophoraflavanone G had antimicrobial effect on all the strains use in the study with 16-64 microg/ml, 8-64 microg/ml, and 1-8 microg/ml of MIC values, respectively. These results indicate that OA, UA, and sophoraflavanone G could be useful in the development of antiseptic solution for washing the root canal in endodontic treatments.

Actinobacillus actinomycetemcomitans, a gram-negative, capnophiTic bacterium, is associated with several human diseases including periodontal disease. Products of A. actinomycetemcomitans exert immunomodulatory effects on various lymphoid populations, some of which may be implicated in the pathogenesis of periodontitis. It has been recently suggested that some of periodontopathic bacterial products might possess superantigenic (SAg) activities. In order to examine SAg activity of A. actinomycetemcomitans, we tried to purify immunomodulating factor (IMF) which can induce proliferation of mouse splenocytes and human PBMC. IMF fraction was obtained from the culture supernatant of A. actinomycetemcomitans by alcohol precipitation, ultrafiltration, size exclusion chromatography, and dye ligand affinity chromatography which has been widely used for the puri5cation of known SAgs. SDS-PAGE analysis showed that the factor migrated to a molecular mass of 40 kDa. The concentration of IMF which elicited maximal proliferative response of mouse splenocytes was ranged 1-10 ug/ml of protein on day 3 in culture. Human PBMC gave a similar response profile to IMF, but their maximal response was obtained by lower concentraion of IMF on day 2 in culture. This activity of IMF was heat and proteinase K sensitive and was not blocked by co-incubation with polymyxin B, a ligand for the lipid A region of lipopolysaccharide. T cell-enriched fraction of mouse splenocytes obtained by nylon wool column lost the response to IMF. Even though mitomycin C-treated antigen presenting cells were added to T cell-enriched fraction, the response to IMF was feeble as compared to unfractionated cells. Splenocytes depleted of T cells by anti-Thy 1.2 and complement also did not respond to IMF. These findings demonstrated that T cells are responsible for a minor proportion of the observed proliferation induced by IMF and the help of these cells are essential to the most of the proliferating cells which may be B cells. This observation was confirmed by flow cytometric analysis of responding lymphocyte subpopulations. These results indicate that IMF of A. actinomycetemcomitans does not act in a manner consistent with known SAgs but is more relevant to the explanation of pathologic findings of periodontal lesions.
