  • MAP kinases are a family of serine/threonine specific protein kinases becoming activated in response to different proliferative stimuli by phosphorylation at both threonine and tyrosine residue. Present study shows that MAP kinase was purified from P388 murine leukema cells by SP sephadex C-50, phenyl superose and Mono Q column chromatography and identified with anti-ERKl antibody by western blotting. Immnublotting analysis to the crude extract of P388 cell lysate shows 44 kD and other minor bands but partial purified fraction eluted from phenyl supherose column have 44kD and 66 kD isoform. Subcloned GST-fusion protein from N-terminal of $p56^{kk}$ was tested as a substrate for MAP kinase phosphorylation. It was showed that the wild type and mutant forms(S42A) were fully phosporylated by purified MAP kinase fraction as com-pare with the other mutant form(S59A). This finding suggest that those GST-fusion proteins may be used as substrate for the in vitro test of MAP kinase.

  • Objectives: This study was performed to analyse single dose toxicity of pure melittin(Sweet Bee Venom-Sweet BV) extracted from the bee venom by utilizing protein isolation method of gel filtration. Methods: All experiments were conducted at Biotoxtech, a non-clinical studies authorized institution, under the regulations of Good Laboratory Practice (GLP). Six weeks old female Sprague-Dawley rats were chosen for the pilot study and determined 30㎎/㎏ which is 4285 times higher than the clinical application dosage as the high dosage, followed by 15 and 7.5㎎/㎏ as mid and lose dosage, respectively. Equal amount of excipient to the Sweet BV experiment groups was administered as the control group. Results: 1. No mortality was witnessed in all of the experiment groups. 2. Hyperemia and movement disorder were observed around the area of administration in all groups, and higher occurrence in the higher dosage groups. Hyperemia and movement disorder diminished with elapsed time. 3. For the weight measurement, male groups showed larger reduction in weight in accordance with higher dosage. Female groups didn't s how significant changes. 4. To verify abnormalities of organs and tissues, cerebellum, cerebrum, liver, lung, kidney, and spinal nerves were removed and conducted histological observation with H-E staining. No abnormalities were detected in any of organs and tissues. 5. One female rat in the 30㎎/㎏ group had amputated toe near the administered area and histopathological finding was hemorrhage with inflammation. This is presumed as a secondary infection after the administration of Sweet BV. Conclusion: Above findings suggest Sweet BV is relatively s safe treatment medium. Further studies on the subject should be conducted to yield more concrete evidences.

  • Kawasaki disease is an acute systemic inflammatory disorder, the etiology of which has not yet been established. The clinical manifestations are non-specific and are common to many pediatric infectious and immunologic diseases. In 2 cases presenting fever, cervical lymphadenopathy, and retropharyngeal abscess-like lesions on the neck shown in a computerized tomography (CT) scan, the diagnosis of Kawasaki disease was delayed. The patients were not responsive to antibiotic therapy, and fluid collection was not found during retropharyngeal aspiration. They showed typical Kawasaki manifestations over time and atrioventricular valve regurgitation in the echocardiogram. A diagnosis of Kawasaki disease should be considered in similar cases of fever and cervical lymphadenopathy. A CT scan that shows a retropharyngeal abscess-like lesion on the neck can be a false positive finding, and other laboratory exams, including echocardiography, should be performed as early as possible to avoid unnecessary medical and surgical procedures.

  • Background and Objectives : Despite of high prevalence, Tinnitus remains obscure because the cause and mechanism is poorly understood. In the absence of a suitable animal model, past investigations tool place in humans. Recently, the animal model with sodium salicylate ototoxicity is broadly used because of its reversibility. Balyangtongum-Tang had been used clinically to treat tinnitus and other hearing problems. We investigated the effects of Balyangtongum-Tang on cochlear morphologic change induced by sodium salicylate ototoxicity and were to find out its therapeutic effects on ototoxicity in rat model. Materials and Methods : Healthy ten Sprague-Dawley rats were divided into normal(2), control(4) and sample(4) groups. The sample group was given extract of Balyangtongum - Tang(1cc/100g) once a day for 4 days. After 3 hours when last medication were given, the sample and control groups were injected intraperitoneally with sodium salicylate(500mg/kg). We observed the cochlear morphologic changes of rats every 1, 2, 3 and 5 hours after injection. Results : The electron microscopic finding of outer hair cell shows some changes in the curticular plate and cytoplasm. Some vacuoles were found in the control and sample groups. Vacuolization in the curticular plate and cytoplasm of the sample group after 3, 5 hours were similar to the control group. But the curticular plate of the sample group after 1, 2 hours did not from vacuole. On the other hand the control group after 1, 2 hours formed vacuoles in the curticular plate. Light microscopic findings of cochlear duct in control and sample groups didn't find any difference. Conclusion : The results suggest that extract of Balyangtongum-Tang reduces the morphologic changes induced by sodium salicylate ototoxicity and the effects are remarkable in frist 2 hours. However the effective times are different with previous studies, it seems to due to the difference of tolerance and sensitivity of laboratory animals.

  • Adenocarcinomas (AC) are the most frequently encountered carcinomas. It may be quite challenging to detect the primary origin when those carcinomas metastasize and the first finding is a metastatic tumor. This study evaluated the role of sex hormone binding globulin (SHBG) positivity in tumor cells in the subclassification and detection of the original organ of adenocarcinomas. Between 1994 and 2008, 64 sections of normal tissue belonging to ten organs, and 116 cases diagnosed as adenoid cystic carcinoma and mucoepidermoid carcinoma of the salivary gland, lung adenocarcinoma, invasive ductal carcinoma of the breast, adenocarcinoma of stomach, colon, gallbladder, pancreas and prostate, endometrial adenocarcinoma and serous adenocarcinoma and mucinous adenocarcinoma of the ovary, were sent to the laboratory at the Department of Pathology at the Yuzuncu Yil University School of Medicine, where they were stained immunohistochemically, using antibodies against SHBG. The SHBG immunoreactivity in both the tumor cells and normal cells, together with the type, diffuseness and intensity of the staining were then evaluated. In the differential diagnosis of the adenocarcinomas of the organs, including the glandular structures, impressively valuable results are encountered in the tumor cells, whether the SHBG immunopositivity is evaluated alone or together with other IHC markers. Further extensive research with a larger number of cases, including instances of cholangiocarcinoma and cervix uteri AC [which we could not include in the study for technical reasons] should be performed, in order to appropriately evaluate the role of SHBG in the differential diagnosis of AC.

  • This paper proposes an e-logistics system supporting efficient vehicle moving trajectory management. Recent advances in wireless communications have given rise to a number of location-based services including logistics vehicle tracking, cellular phone user's location finding, and location-based commerce. Logistics systems typically entail tracking vehicles for purposes of the logistics center knowing the whereabouts of the vehicles and/or consignments. Moreover, storing and managing location trajectory of continuously moving vehicles and consignments is necessary for supporting efficient logistics plan and consignment. The proposed system is able to manage spatial objects in GIS as well as logistic information in the mobile environment. And for the efficiently managing and retrieving of transporting trajectory of logistics, we extend previous moving object indexing method, TB-Tree, to use multi-version framework and evaluate data updating performance. It is able to apply the proposed method to develop mobile contents services based on continuously changing location of moving object in the mobile environment.

  • Background : Although chronic non-bacterial prostatitis is increasing, it is hard to treat effectively. In western medicine, antimicrobials drug, ${\alpha}$-adreno-ceptor antagonists, anti-inflammatory drugs, tricyclic antidepressants and anticholinergic agents are used commonly, but chronic prostatitis/chronic pelvic pain syndromes is confusing and frustrating for urologist. IDS(Indongsoyeom-bang) is used in treatment of chronic prostatitis/chronic pelvic pain syndromes. And it is reported that GLS(Gleditsiae spina) and TOF(Toosendan fructus) components of IDS have significant effect on protection of the glandular epithelial cells. Objective : In this study was conducted to investigate the therapeutic effects and action machanism of IDS in the rat model of non-bacterial prostatitis induced by castration and testosterone treatment. Methods : We observed six experimental objects of normal group, control group, testosterone group, and IDS 50 mg/kg, 200mg/kg, 400mg/kg group. Rats were treated with 17 ${\beta}$-estradiol after castration for induction of experimental non-bacterial prostatitis, which is similar to human chronic prostatitis in histophatological profiles. IDS and testosterone were administered as an experimental specimen and a positive control, respectively. The prostates were evaluated by histological parameters including the epithelial score and epithelio-stromal ratio for glandular damage. Also, the prostates were observed by Hematological alterations of WBC, RBC, hemoglobin and platelet. Results : While prostates of control rats revealed severe acinar gland atrophy and stromal proliferation, the rats treated with IDS-50 showed a diminished range of the tissue damage. Epithelial score was improved in IDS than that of the control. The epithelio-stromal ratio was lower in IDS when compared to that of the control. Also, the examination of bloods were not observed hematological change. Conclusion : These finding suggests that IDS may protects the glandular epithelial cells. We concluded that IDS could be a useful remedy agent for treating chronic non-bacterial prostatitis.

  • Sarcoidosis is a multi-systemic granulomatous disorder of unknown etiology. The characteristic pathological finding is the presence of non-caseating granulomas. The lungs are primarily affected, however other organs may be involved causing various symptoms and ambiguous laboratory findings can be present. There are a few reported cases of sarcoidosis with elevated tumor markers. We describe a 68-year-old woman presenting with sarcoidosis showing elevated serum carcinoembryonic antigen (CEA). The possibility of cancer arising from serum CEA such as gastrointestinal cancer, breast cancer and lung cancer was excluded. A transbronchial lung biopsy demonstrated a non-caseating granuloma without necrosis. As a result prescribed 30 mg prednisolone daily to the patient and serum CEA was decreased after 1 month of treatment. We report a case of pulmonary sarcoidosis with elevated serum CEA.

  • To evaluate an effect of pathological liver damage on the conjugation of cyclohexane metabolites, rats were pretreated with 50% $CCl_4$ dissolved in olive oil (0.1 ml/100 g body weight) 10 or 17 times intraperitoneally at intervals of every other day. On the basis of liver function, the animals pretreated with $CCl_4$ 10 times were identified as acutely liver damaged ones and the animals pretreated with $CCl_4$ 17 times were identified as severly liver damaged ones. To these liver damaged animals, cyclohexane (a single dose of 1.56 g/kg body weight, i.p.) was administered at 48 hr after the last injection of $CCl_4$. The rats were sacrificed at 4 or 8 hr after injection of cyclohexane. The cyclohexane metabolites, cyclohexanol (CH-ol), cyclohexane-1,2-diol (CH-1,2-diol), cyclohexane-1,4-diol (CH-1,4-diol), and their glucuronyl conjugates and cyclohexanone were detected in the urine of cyclohexane treated rats. The urinary concentration of cyclohexane metabolites was generally more increased in liver damaged animals than normal ones, and the increasing rate was higher in $CCl_4$ 17 times injected rats than 10 times injected ones. And liver damaged.ats, especially $CCl_4$ 17 times treated ones, had an enhanced ability of glucuronyl conjugation to CH-ol analogues compared with normal group. Futhermore, CH-1,2 and 1,4-diol were all conjugated with glucuronic acid in $CCl_4$ 17 times injected animals. On the other hand, the increasing rate of activities of hepatic cytochrome P450 dependent aniline hydroxylase, alcohol dehydrogenase and urine diphosphate glucuronyl transferase was higher in 17 times $CCl_4$-treated rats compared with normal and $CCl_4$ 10 times injected animals. Taken all together, it is assumed that an increased urinary excretion amount of cyclohexane metabolites in liver damaged rats might be caused by an increase in the activities of cyclohexane metabolizing enzymes. And enhanced conjugating ability of CH-ol in liver damaged animals and novel finding of conjugating form of CH-1,2 and 1,4-diol might be caused by increase in the activity of hepatic diphosphouridine glucuronyltransferase.

  • Objectives : In this study, for before/after dental implant surgery, our aim is to provide the basic data based on the decision of the treatment by measuring satisfaction of the treatment and finding out the intention to revisit a hospital and also by recommendation. Methods : We conducted the frequency analysis, a cross-tabulations, paired t-test and a correlation analysis of 146 data who had visited at 6 dental clinics and hospitals located in Daegu for dental implant surgery, with SPSS (PASW 18.0 for Windows, SPSS Inc, USA) to find out the satisfaction of the treatment before/after dental implant surgery. Results : The satisfaction related to before/after dental implant surgery of oral health was all statistically significant on a masticatory, social and psychological function, the satisfaction towards the treatment, the intention to revisit a hospital and also by recommendation. Independent variables explained the satisfaction of the treatment before/after dental implant surgery as 19.1% and indicated a significantly high value in general. Conclusions : The satisfaction was higher on satisfactory of the postoperative treatment than on satisfactory of the preoperative treatment in spite of these limitations. Therefore, the dental medical team should take into account dental implanting as a way which improves the satisfaction of the treatment related with oral health and have continuous managements and careful concerns.
