PURPOSE: To identify the four layers based on intranodular vascular nature visible in multiphase incremental bolus dynamic CT and to determine any differential points according to various factors of liver abscess with this vascular nature or not. MATERIALS AND METHODS: We categonized 29 cases of confirmed liver abscess into three different groups according to presence of four layers visible in early phase(arterial phase) of CT. Three groups were compared in regard to the results of antiamebic antibody test and bacteriologic study and presense of cholangitic abscess and internal septation. RESULTS: We could separate four layers, innermost hypodense central cavitary lesion, hyperdense granular tissue, hypodense abscess wall and outermost hyperdense compensatory hypervascular zone in 18 cases(62%), only two layers, cavity and wall in six cases(21%), and characteristically we could find three layers without innermost cavitary lesion in five cases(17%). But we couldn't find significant correlations between various clinical factors of liver abscess and our vascular groups. CONCLUSION: Our method of CT could represent four layers based on vascularity in 62% of cases. And also could find the unusual inflammatory mass containing three layer which must be differentiated from other malignant solid mass. But we couldn't find differential point between various clinical factor of liver abscess and imaging diagnosis. We think that with the improvement of hardware such as spiral CT, identification of four layers will be earier and will be very helpful in early detection and proper treatment planning of liver abscess.

This study aims at the developing of a computer program for the evaluation of nursing care quality. Since the professional nursing care requires a consistent evaluation, the computer program for the measurement of quality of nursing care is necessary. It provides the nursing care with an effective and efficient management of nursing quality. In this study, a computer program is developed as a module. The evaluation criteria are structured in a hierarchical manner. Each evaluation area includes several items, which again have their own indicators. The system consists of 7 evaluation areas, 32 evaluation items, and 71 indicators. Scoring is possible with the evaluation items. The scoring types of the program are of two types, that is, the norm-referenced type(option 1) and the criterion-referenced type(option 2). With this program, an accurate and consistent evaluation of nursing care with the rapid feedback to nursing care practice is expected.

In clinical setting, treatment-refractoriness, medication induced tardive dyskinesia and amenorrhea in chronic schizophrenia are frequently problematic. However, there are few guideline solving these problem available to clinicians. The goal of this study was collecting clinical data on clinical effeciveness and predictors of response of switching to olanzapine. We attempted to switch to olanzapine from risperidone and clozapine in chronic 31(risperidone 17, clozapine 14) schizophrenia and schizoaffective disorder patients suffering from sustained symptoms, weekly blood monitoring, medication induced tardive dyskinesia and amenorrhea. Previous antipsychotics dosage was gradually decreased for 2 or 3 weeks, at the same time olanzapine dosage was gradually increased. At baseline, after 1 week, after 2 weeks and after 4 weeks we checked Brief Psychiatric Rating Scale, Clinical Global Impression Scale, Sympson-Angus Rating Scale, Barnes Akathisia Rating Scale and Followed up after 12 months. Successful switch after 4 weeks was achieved in 25 patients(clozapine 9(64.2%), risperidone 16(94.1%). Overall, mean BPRS and CGI scores increased significantly. Successful maintenance after 12 months was achieved in 17 patients(clozapine 5(35.7%), risperidone 2(70.5%). Overall, mean BPRS and CGI scores increased significantly too. Switching to olanzapine from other atypical antipsychotics is recommendable in chronic schizophrenia with treatment refreactoriness and drug induced side effect.

Development of antibody-based cancer therapies will be greatly facilitated if antibodies are better standardized in two fundamental issues that are specificity analysis of antibody reactivity and the detailed biodistribution and pharmacokinetic profile of antibodies. In the current endeavor we attempted to use an antibody binding specificity to target the tumor in a syngeneic carcinoembryonic antigen (CEA) tumor model. CEA, a 180 kDa glycoprotein, expressed at high levels on the surface of nearly all tumors of the gastrointestinal tract was used a potential target for antibody immunotherapy of gastrointestinal carcinomas. Using the CEA model antibody-based cancer therapy directed against CEA has been evaluated in a syngeneic animal model of disseminated disease. We constructed mouse/human chimeric anti-CEA IgG3, which has been evaluated for the specificity for CEA and the detailed biodistribution and pharmacokinetic profiles. Anti-CEA IgG3 heavy chain was expressed with the expected 180kDa molecular weight, assembled as H2L2 forms with a co-expressed mouse/human chimeric anti-CEA light chain, and were secreted. On FACS the purified anti-CEA IgG3 specifically recognized the mouse colon adenocarcinoma cell line MC-38 transduced with CEA (MCA32a), but not MC 38 without expressing CEA. After subcutaneous injection in C57BL/6 mice the half- lives of anti-CEA IgG3 and an irrelevant anti-dansyl IgG3 showed the bi-phasic kinetic patterns, and their pharmacokinetics of the distribution and the elimination were similar in mice. However, the biodistribution patterns of anti-CEA IgG3 were very different from those of anti-dansyl IgG3. Anti-dansyl IgG3 was mainly distributed into kidney until 72 hours, but anti-CEA IgG3 was slowly rernoved from blood and distributed into liver, kidney, spleen, and tumor. It is note worthy that anti- CEA IgG3 increased in targeting MCA32a tumor expressing human CEA by time, but the targeting to MC38 tumor was negligible. Thus, the increased targeting of anti- CEA IgG3 made MCA32a tumor grow slowly

To generate drug delivery vector to locales in the body, genetic engineering and expression techniques have been used to produce antibody avidin fusion proteins. Chicken avidin has been fused to mouse-human chimeric IgG3 immediately after the hinge with a flexible linker (H-Flex-Av) and at the end of CH2 (CH2-Av). Fusion heavy chains were expressed with the expected molecular weight, assembled as H2L2 forms with a co-expressed light chain, and were secreted. The expression level of H- Flex-Av was 1~10 ug/ml/10(8)/24 hrs, but that of C2-Av was a very little (0.08~0.9 ug/ ml/10(8)/24 hrs). The resulting H-Flex-Av and CH2-Av fusion proteins continued to bind antigen dansyl and also bound biotinylated bovine serum albumin; both H-Flex-Av and CH2-Av had shown to retain 3-4 times higher relative affinity than that of CH3-Av in ELISA. Importantly the fact that both avidin fusion proteins had a higher relative affinity suggests that these avidin fusion proteins can be effectively used to deliver biotinylated ligands such as drugs and peptides to a certain locale, such as the brain.
