<P>Reactive oxygen species (ROS), generated by ionizing radiation, has been implicated in its effect on living tissues. We confirmed the changes in the oxidative stress markers upon irradiation. We characterized the changes in the proteome profile in rat liver after administering irradiation, and the affected proteins were identified by MALDI-TOF-MS and ESI-MS/MS. The identified proteins represent diverse sets of proteins participating in the cellular metabolism. Our results demonstrated that proteomics analysis is a useful method for characterization of a global proteome change caused by ionizing radiation to unravel the molecular mechanisms involved in the cellular responses to ionizing radiation.</P>

The students who study in GLE(=Globalized and Localized experts) program must have a good command of English, especially in speaking and listening when they complete whole courses. In order to achieve this aim successfully the English curriculum for the GLE should be organized systematically as well as the intellectual faculties of the students, teaching methods and the beginning age of English teaming should be considered seriously We researched the learning theories of a foreign language and the four functional skills of language and proposed a few hints that the students in the GLE keep in mind while they learn English. The results obtained from this paper are summarized as follows: 1. The students who study in the GLE can effectively improve the ability of the command of English not through the way of language acquisition but through the way of language learning because they began to learn English at middle school days. In fact at the age of over 12 or 13 the language acquisition faculty has grown and consequently the value of linguistic parameters has already been set. 2. When the students in the GLE learn English, the emphasis should be laid on the improvement of speaking and listening ability primarily and then reading and writing ability should be developed. 3. It is necessary that the students understand the British and American social and cultural properties fully. As a particular language is the product of the social and cultural life of a certain language group, language learning always includes the understanding of the social and cultural properties of the people who use the target language.

This paper described a collaborative exercise intended to see what kinds of short tandem repeat (STR) loci are used in different DNA typing laboratories in Korea and to compare their results for the demonstration whether uniformity of DNA profiling results from different laboratory could be achieved in Korea Laboratories were asked to test five tissue DNAs using methods routinely used in each laboratory and to report the results to the coordinating laboratory. The exercise demonstrated that each laboratory was using different STR loci for the typing with different STR numbers,2 VNTRS,36 STRs and amelogenin in total, and the direct comparison of the results from all the laboratory for the 18 loci could not be done as only one laboratory submitted typing results. Among 21 loci for which several laboratories submitted typing results, results for 14 loci were the same and results for the other 7 loci were different depending on the participating laboratory. D1S80, F13A01, D16S539, D21S11, D18S51, D3S1744 were the loci with different typing results. Even in the cases where commercial kits were used, the results were not the same depending on the machines used, that is the capillary electrophoresis or the gel based electrophoresis. The reason for the different results, points about the standardization of the methods arid the profiling data were described.

의약품 및 동물약품으로 사용되고 있는 분말유산균을 개발하고자 동물의 장에서 산성 pH 및 담즙산에 대한 내성이 강하고 대장균 생육억제력이 좋은 Enterococcus faecium L20을 분리 동정하고 이를 이용하여 고농도의 생균이 함유된 분말 유산균을 제조하였다. 분리된 균주는 pH 3.0에서 90% 이상의 내성과 0.3% 담즙산이 함유된 배지에서 100%의 내성을 나타냈으며 MRS 배지에서 대장균과 혼합배양시 24시간 이내에 대장균을 사멸시켰다. 분리된 균주를 산업용배지에서 배양한 후 동결건조시켜 분말을 만들었을 때 생균수는 5.0×0^11/g 이상이었다. 이것은 18℃에 보관하였을 경우 11개월 동안 80%의 생존율을 나타내었다. In order to develop a lactic acid bacterial powder which can be used as a probiotic for human and animal, a lactic acid bacteria which has high resistance against low pH and ox-gall, and shows a good growth inhibition against low pH and ox-gall, and shows a good growth inhibition against E. coli, was isolated from an animal intestine and characterized. The isolated strain was identified as Enterococcus faecium. It had more than 90% of survival at low pH for 2 hours and almost 100% of survival in the presence of 0.3% ox-gall. When co-cultured with E. coli in MRS broth, all of the E. coli cells were killed within 24 hours. The final powdered product of the isolated strain was manufactured after a freeze drying process suing an industrial media, and then checked its stability. Its storage stability was 80% for 11 months at 18℃.

To study anti-cancer effect and molecular biological mechanism of bee venom for aqua-acupuncture, the effects of bee venom on cell viability, apoptosis, and cell cycle were analyzed using MTT assay, tryphan blue assay, [3H]thymidnine release assay, flow cytometric analysis, activity of caspase-3 protease activity assay, and immunocytometric analysis of PCNA. To explore whether anti-cancer effects of bee venom are associated with the transcriptional control of gene expression, quantitative RT-PCR analysis of apoptosis- and cell cycle-related genes was performed. The obtained results are summarized as follows: 1.The MTT assay demonstrated that cell viability was decreased by bee venom in a dose-dependant manner. 2.Significant induction of apoptosis was identified using tryphan blue assay. [³H]thymidine release assay, and flow cytometric analysis of sub G₁fraction. 3.In analysis of caspase-3 protease activity, the activity had increased significantly, in a dose-dependant manner. 4.Quantitative RT-PCR analysis of the apoptosis-related genes showed that Bcl-2 and Bcl-X□ were down-regulated whereas Bax was up-regulated by bee venom treatment. 5.In flow cytometric analysis of cell cycle and immunocytometric analysis of PCNA expression, cell numbers of G₁phase was increased by a dose-dependant manner. 6.In quantitative RT-PCR analysis of the cell cycle-related genes, p21, p27, and p57 were increased, while Cyclin D1, CDK4, c-Myc, c-Fos, and Histone H3 were decreased. In contrast, there were no remarkable changes in expression levels of CDC2 and c-Jun.

A 2cm sized solid mass was observed in the right inguinal lesion of a 10-years old poodle bitch. Radiological finding in the mass showed higher density than that of soft tissue and thoracic radiograph showed pulmonary interstitial pattern. Gross findings appeared a yellowish-brown solid mass containing cysts filled with brown colored mucoid fluids in the udder. And the lung showed multiple nodules scattered throughout the pulmonary parenchyma. In light microscopic finding, mass contained neoplastic proliferation of glandular epithelial and myoepithelial cells and showed metaplstic lesions of these cells to chondrous tissue. Glandular epithelial cells were undifferentiated and polygonal myoepithelial cells were frequently embedded in or surrounded by a pink to light blue mucinous matrix. Tumor cells of the pulmonary nodule had resemblance to neoplastic proliferation of glandular epithelial and myoepithelial cells observed in the mammary gland mass. Based on the gross and microscopic findings, the mass was diagnosed as malignant mixed tumor with metastasis to the lung.
