This study was focused on improvement of milk production in Mongolia dairy industry by artificial insemination (AI) technology, of which was supported from ODA project of KOICA in Republic of Korea. The study was started from January 2009 to present and 3rd years in this year. So, all data, especially synchronization and pregnancy of dairy cows (Holstein) will be summarized in final result in this year. For synchronization, total 81 dairy cows selected from 4 private farms that were 38, 30, 8 and 5 in Undarmal milk, Onjin (Enkhbayer), Jargalant, and BRM School, respectively. All the dairy cows were injected intramuscular (IM) of 5 ml PGF2α in the vulva and detected estrus 2 to 3 days after PGF2α injection. Total 78 out of 81 dairy cows (96.3%) were detected estrus by only 1 time injection of PGF2α. The dairy cows that were induced estrus, inseminated with 0.5 ml dairy frozen semen by conventional AI techniques. The pregnancy diagnosis of the AI dairy cows was detected by uterus palpation after 60 days of insemination. Total 75 from 78 inseminated dairy cows (90.1%) were diagnosis pregnant. The estrus induction and pregnant rate were very effective using PGF2α injection and conventional AI techniques in Mongolia dairy cow. The results indicated that AI after estrus induction in Mongolia dairy cows could be applied to dairy breeding technology to improve the breeding efficiency and milk production.

However, Endoscopic retrograde cholangiopancreatography (ERCP) is still helpful procedure for the diagonosis of the pancreatobiliary disease and treatment through endoscopic sphinterectomy (EST) is relatively safe, these have possiblity of complications such as hemorrhage, infection, panceatitis, and perforation. ERCP related perforation was rarely reported in 0.3 to 1.1% of previous study, but most serious complication. A report of Pneumomediastinum, Tension Pneumothorax complicating perforation after ERCP and EST is very uncommon. In our hospital, we experienced case of pneumomediastinum, subcutaneous emphysema, and tension pneumothorax after ERCP and EST, and the patient (a 58 years old female with suspicious common bile duct stone) was treated successfully with conservative treatment.

Intercellular adhesion molecule-1 (ICAM-1) is a glycoprotein serving as ligands for leukocyte intergrin receptors, i.e. LFA-1, MAC-l. It has been suggested that the expression of ICAM-1 and the levels of circulating ICAM-1 were increased in several malignancies. We measured serum ICAM-1 by ELISA in patients with stomach cancer (n=25), acute lymphoblastic leukemia (n=7), non-Hodgkin's lymphoma (n=14), and metastasis of unknown origin (n=5). Serum levels of circulating ICAM-1 in all malignancies were significantly higer than in normal controls. And serum level of ICAM-1 in stomach cancer ptients having metastatic disease was higher than in patients with localized disease (p=0.027). These results suggest that elevated serum ICAM-1 is a rather common feature for malignancies, not unique for certain types of cancer such as malignant melanoma. It remains to be clalified whether marked increase of serum ICAM-1 in metastatic stomach cancers simply reflect tumor burden or this molecule plays a role in progression in stomach cancer.

The use of cyclosporine(CsA), a potent immunosuppressive agent, is associated with numerous side effects. Neurotoxicity was earlier less well known, but with growing experience central nervous system side effects are now reported up to 40% of patients. Among various CsA-induced neurotoxicities, tremor is most common and posterior leukoencephalopathy is well characterized. An encephalopathy presenting with pyramidal weakness, however, seems to be rare and poorly documented. We report here a case of encephalopathy presenting with multiple generalized seizures followed by fluctuating quadriparesis developed a few days after starting CsA and resolved spontaneously after withdrawal of the drug . A 48-year-old woman with aplastic anemia was placed upon immmunosuppressive treatment consisting of antithymocyte globulin(ATG), CsA, and methylprednisolone. Two days after starting the therapy, she developed a generalized seizure. The next day she developed 2 more episodes of seizure and the therapy was stopped. Computed tomogram of the brain was normal. Six days after starting therapy, she developed mild motor weakness and paresthesia of both lower extremities, which progressed to a definite quariparesis confining her to a bed in 3 days. Magnetic resonance imaging(MRI) of the brain revealed asymmetric, bilateral high-signal abnormalites in the subcortical white matter of fronto-temporal areas. After reaching to a maximum with some fluactuation(14 days after starting the therapy) the motor weakness started to be resolved. She was discharged with a almost complete resolution of the weakness 45 days after starting the therapy. Five months later she did well and brain MRI was negative.

Health Risk Appraisal(HRA) is usually defined as a process by which we expect of individual's chances of death or acquiring specific diseases within a defined period of time. The concept of worksite as an area of health maintenance and promotion is newly developing. Our movement for health promotion of employees has been increasingly known in the worksite. The aim of this study is to develop health risk appraisal tools about health promotion at the worksite for employees. We performed this study by two steps; one step was to develop a HRA questionnaire of worksites in Korea, another was to evaluate the reliability of the questionnaire. For developing HRA questionnaire, we reviewed scientific examples at first, and then weighted the score by delphi. To evaluate the reliability of developed questionnaire, we carried out survey by test-retest method. A total of 131 employees completed HRA questionnaire on two times. The results are as follows. The total score of health risk in unhealthy workers was higher than that of healthy workers. The range of test-retest reliability of responses to the questionnaire was 0.57-0.94. Therefore it seems that this questionnaire was very suitable to assess the health behavior of workers. In conclusion, the developed HRA questionnaire can be used as a tool for evaluating health behavior and for providing health counseling materials.

Cardiac tumors, especially the primary tumors involving any part of the heart are extremely rare and its relative incidence has been reported to be approximately 0.02%. We report a patient with huge cardiac hemangioma who complained of shortness of breath, general weakness, and dizziness, Imaging study by echocardiography and computed tomography of thorax revealed a huge lobulating mass like a bunch of grapes in the right chamber of heart. The surgical exploration of thorax was performed and a histological diagnosis of spindle cell hemangioma was obtained by microscopy. The patient was treated by surgical resection of the tumor and doing well after surgery. Our experience indicated that prompt diagnosis and treatment of cardiac hemangioma is imperative for patients' prognosis.

The bcl-2 proto-oncogene encodes a 26 kD protein that promotes cell survival by blocking apoptosis. The bax protein is a member of the bcl-2 familly, now known to form heterodimers with the bcl-2 protein. The ratio of bax to bcl-2 is be critical in determining the fate of the cell in response to stimuli that can induce apoptosis. Extract of Pulsatilla Koreana (SB-31) showed promising antitumor activity in vitro with Topo I inhibitory action. In the present study, the relationship between apoptosis and the apoptosis related proteins, bcl-2 and bax were investigated in human leukemic cell lines HL-60, U-937 and CEM-CM3. All anticancer drugs(adriamycin, etoposide, camptothecin, SB-31) induced extensive apoptosis in HL-60, U-937 cells and CEM-CM3 cells. The expression of bcl-2 and bax protein were determined in cell lines by western blotting before and after incubation with anticancer drugs at different time points. 1) In HL-60 or U-937 cell lines, down regulation of bcl-2 and up-regulation of bax were found after incubation with ADR, VP-16 or camptothecin. 2) In HL-60 or U-937 cell lines, no significant change in bcl-2 or bax protein expression resulted after incubation with SB-31. 3) In CEM-CM3 cells, virtually no change was noted in bcl-2/bax expression after incubation with ADR, VP-16, camptothecin or SB-31. It is suggested that different leukemic cell lines use different pathways of apoptosis activation and a given cell may utilize different pathways of apoptosis activation in response to different cytotoxic agents.

Although acute lymphoblastic leukemia(ALL) is one of the most frequently encountered cancer in children, only about 20% of patients who were diagnosed leukemia are ALL in adults. During past 30 years, the result of treatment of ALL in children have been markedly improved, but in adults, the result of treatment of ALL is not so good as that in children. In recent, morbidity of ALL has been increased in KOREA, but studies of long-term survival are rare. So a retrospective clinical analysis was made in patients who were diagnosed for adult acute lymphoblastic leukemia between March 1988 and February 1997, in Chungnam National University Hospital. The result of treatment, prognostic factors of survival and duration of complete remission were analyzed. In 44 patients who were newly diagnosed as ALL in Chungnam National University Hospital, total 31 patients who have received chemotherapy more than two weeks were analyzed. All patients were treated by vincristine, daunorubicine, and prednisolone in phase I induction chemotherapy. At the 28th day of phase I induction chemotherapy, bone marrow aspiration biopsy was performed and achievement of complete remission was estimated. Within one or two weeks after completion of phase I chemotherapy, phase II induction chemotherapy was done. In phase II induction chemotherapy, cyclophosphamide, cytosine arabinoside and 6-mercaptopurine were administerd. During phase II induction chemotherapy, CNS prophylaxis with intrathecal methotrexate administration and intracranial irradiation. After completion of phase I and phase II of induction chemotherapy, 4 cycles of consolidation chemotherapy were made in utilization of VP-16 and cytosine arabinoside in standard risk group, and in utilization of methotrexate with leucovorin rescue and L-asparaginase in the high risk group. And then maintenance chemotherapy with 6-mercaptopurine and methotrexate was continued till two years later from the day of treatment start. The median survival time was 15.8 months (95% C.I. 6.0-18.8 months) and the long-term survival (more than 5 years after diagnosis) rate was 28.0%. The rate of complete remission was 83.9% ( 26 of 31) and the median of the complete remission duration was 15.8 months (95% C.I. 5.6-25.9 months). The rate of relapse was 69.2%. Good prognostic factor for overall survival time was the fraction of blast cells less than 75% in bone marrow at diagnosis (P=0.001) in univariate analysis. In multivariate analysis, age below 40 (P=0.003) and blast cells less than 75% in hone marrow at diagnosis (P=0.003) were good prognostic factors for overall survival time. Good prognostic factors for disease free survival in univariate analysis were the fraction of blast cells less than 75% in bone marrow (P=0.003), absence of fever (P=0.013), and absence of hepatomegaly (P=0.025), all at diagnosis. In multivariate analysis, good prognostic factors for disease free survival were platelet count more than 50,000/uL, blast cells less than 75% in bone marrow at diagnosis (P=0.004), serum LDH level below 500U/L (P=0.016). The result of treatment of ALL in adults has been improved but is not satisfactory in comparison with that in children. Despite of marked improvement of the rate of complete remission, the rate of relapse still not so much improved. So intensified consolidation chemotherpy or allogenic bone marrow transplantation or autologous bone marrow transplantation is necessary for improvement of survival of adult ALL.
