A retrospective study was performed to evaluate the effects, and side effects, of epidural analgesia for postoperative pain relief of 2,381 surgical patients who received general-epidural, or epidural anesthesia only. Anesthesia records, patients charts, and pain control records were reviewed and classified according to: age, sex, body weight, department, operation site, epidural puncture site, degree of pain relief by injection mode & epidural injectate, and side effects(including nausea, vomiting, pruritus, urinary retention and respiratory depression). The results were as follows: 1) From the total of 2,381 patients, there were 1,563(66%) female patients; 1.032(43%) patients were from Obstetrics and Gynecology. 2) Lower abdomen, thorax, lower extremity and upper abdomen in the operation site; and lumbar, upper, lower thoracic in puncture site were order of decreasing frequency. Length of epidural injection for pain relief averaged $1.72{\pm}1.02$ days. 3) Ninety three percent of the patients experienced mild or no pain in the postoperative course. Analgesic quality was not affected by the kind of epidural injectate. 4) Nausea occurred in 3.2% of all patients, vomiting in 1.1%, pruritus 0.9%, urinary retention 0.6%, respiratory depression 0.08%. 5) Frequency of nausea was higher with female patients compared to male patients(p<0.05). 6) Pruritus frequency was higher with male patients than female patients(p<0.05); and more frequent with patients who received epidural injection with morphine than patients who received epidural injection without morphine(p<0.01). 7) Urinary retention was higher in female patients, and more frequent with patients who had received epidural injection with morphine than epidural injection without morphine(p<0.05). 8) There were two cases of respiratory depression. The course of treatment consisted of: cessation of epidural infusion, then administration of oxygen and intravenous naloxone. We conclude that postoperative epidural analgesia with a combination of local anesthetics and opiate is and effective method for postoperative pain relief with low incidence of side effects. However, patients should be carefully evaluated as rare but severe complications of respiratory depression may ensue.

청국장으로부터 Bacillus cereus에 대한 항균활성이 가장 높은 균주를 분리하여 형태학적, 생화학적 특성과 16S rDNA 염기서열 결정을 통해 Bacillus subtilis HH28으로 동정 및 명명하였다. B. subilis HH28의 생육시기에 따른 항균활성을 측정해 본 결과, 생육이 대수증식기인 9시간부터 생성되어 사멸기인 60시간에 가장 높은 활성(80 AU/ml)을 나타내었고 144시간(6일)까지 항균활성을 유지하였다. 항균물질의 정제는 황산암모늄 침전과 DEAE-sepharose fast flow, sephacryl S-200HR를 이용하였고, 19.7배의 정제도와 38.4%의 수율로 정제되었다. Tricine SDS-PAGE와 directed detection을 통해 항균물질의 분자량이 약 3,500 Da임을 알 수 있었다. 또한 본 연구의 항균물질을 B. cereus 뿐만 아니라 Listeria monocytogenes, Vibrio parahaemolyticus의 식중독 균에서도 우수한 항균활성을 나타내었고, 항균작용의 기작은 미생물을 사멸시키는 살균작용이였다. 또한 온도 안정성 실험에서 $40-80^{\circ}C$까지 안정했고, pH 안정성 실험에서는 pH 2-9까지 안정하여 비교적 온도와 pH에 안정하였다. 효소에 대한 영향 실험에서는 단백질 분해효소에 의해 항균활성이 실활되어 본 연구의 항균물질은 단백질성임을 알 수 있었다. 위와 같은 특성으로 보아 B. subtilis HH28이 생산하는 항균물질은 천연 식품 보존제 및 사료 보존제, 항생제 대체 의약품으로 사용할 수 있는 잠재력을 가지고 있으며, 향후 이 항균물질의 정확한 구조 및 특성 규명 등의 연구가 필요하다.

Despite advances in surgery, radiotherapy, and chemotherapy, the survival of patients with oral squamous cell carcinoma has not significantly improved over the past several decades. Gene therapy is currently under investigation and shows us new possibility of cancer curing method. This experiment was undergone to find out the cell growth inhibition effect and evidence of apoptosis by HCCS-1(human cervical cancer suppressor-1), one of the candidates of tumor suppressor gene, transducted to human oral cancer cell line. To determine the efficiency of the adenovirus as a gene delivery vector cell line was transducted with LacZ gene and analysed with X-gal staining. Northern blot was performed to confirm the transfection with HSCC-1 gene and cell viability was assessed by cell cytotoxicity assay using cell count kit(CCK). To show the evidence of apoptosis, DNA fragmentation assay and flow cytometry(FACS) were performed. We had successfully construct the recombinant HSCC-1 adenovirus(Ad5CMV-HCCS-1), and importation efficiency was 20% at 2 MOI(multiplicity of infection), 80% at 20 MOI. Northern blot analysis showed that a single 0.6kb mRNA transcript was expressed in Ad5CMV-HCCS-1 transducted cell lines. As a result of CCK, when comparing to control subjects, transducted group showed 50% growth inhibition. In DNA fragmentation assay, according to increasing of MOI, DNA volume was diminished. In FACS analysis, DNA distribution showed fragmentation. This results imply that HCCS-1gene has growth inhibition effect in human oral cancer cell lines through apoptosis induction.

Purpose: A Krukenberg tumor is an ovarian tumor of a signet-ring cell type. This tumor arises more commonly in young women, and the prognosis is poor. The primary focus of this tumor is often found at gastrointestinal malignancy, especially gastric cancer. We tried to identify the clinical characteristics of this tumor, and in that regard, this report might be helpful. Materials and Methods: We reviewed the 61 patients with Krukenberg tumors, who had been diagnosed at our hospital from 1994 to 2002, and retrospectively analyzed the clinical features. Results: The age distribution ranged from 15 to 59 years, and the mean age was 41 years. The most common symptom was a lower abdominal mass ($46\%$). Fourty-two cases ($77\%$) showed bilateral ovarian involvement, and the size of this tumor was variable, but in 24 cases ($4\%$) the size was $5\∼10$ cm for the largest diameter. Among 54 cases, 40 cases had ascites, and the volume of ascites was variable. The median survival of the 61 patients was 10 months, and Krukenberg tumor developed 19.7 months after the primary operation. The median survival durations of recurrence patterns were 20 months for the Krukenberg tumor alone, and 7 months for the Krukenberg tumor with peritoneal seeding. Conclusion: In young women treated with a gastrectomy, especially one for an advanced tumor, closed observation with abdominal ultrasonography or computed tomography to detect a Krukenberg tumor is recommended. The patient with a Krukenberg tumor alone has a better prognosis than one with a Krukenberg tumor combined peritoneal seeding. We will have to consider more progressive treatment for the patient with a Krukenberg tumor alone.

Malignant ovarian tumors in children are very rare, and consist of about 1 % of all childhood malignant tumors. The purpose of this study is to examine the clinical characteristics, treatment, and prognosis for children with malignant ovarian tumors. We retrospectively reviewed the medical records of children under 15 years of age with malignant ovarian tumors who had been treated surgically at Asan Medical Center between 1989 and March 2009. There were 32 patients, ranged in age at surgery from 2 to 15 years (mean; 10.4 years). The median follow-up period was 64.7 months (from 1 month to 188 months). Pathologic diagnosis were; immature teratoma (n=10), mixed germ cell tumor (n=10), and dysgerminoma (n=6). Tumor stage was classified by the staging system of the International Federation of Gynecology and Obstetrics (FIGO). The number of patients in stage I, II, III, and IV were 24 (75 %), 2 (6.2 %), 4 (12.5 %), and 2 (6.1 %), respectively. The tumor recurred in 4 patients. Seven patients of group 1 did not receive postoperative adjuvant chemotherapy, and in three of them, the tumor recurred. Twenty-five patients (group 2) underwent postoperative adjuvant chemotherapy, and there was only one recurrence. One patient who did not receive postoperative adjuvant chemotherapy and expired 10 months after operation because of tumor recurrence and distant metastasis. The overall 5-year event free survival (EFS) was 84.2 %: group 1 in 44.4 %, and group 2 in 95.7 %. Tumor recurrence was related to the postoperative adjuvant chemotherapy (p=0.004). In conclusion, proper surgical procedures with relevant postoperative adjuvant chemotherapy might improve clinical results in children with malignant ovarian tumors.

In spite of the ongoing advances, standard therapies for oral cancer still has some limitations in efficacy and in ability to prolong survival rate of advanced disease and result in significant functional defect and severe cosmetic deformity. Currently gene therapy using tumor suppressor gene is considered as a potent candidate for new therapeutic approaches that can improve efficacy and reduce complications. The purpose of this research is to identify the role of adenoviral vector to transfer HCCS-1 tumor suppressor gene in oral cancer cells and to find out whether there is a possibility for it to serve in the field of gene therapy. The human SCC-25 cell line was used for transfection. To determine the efficiency of the adenovirus as a gene delivery vector cell line was transduced with LacZ gene and analysed with X-gal staining. Northern blot was performed to confirm the tranfection with HSCC-1 gene and cell viability was assessed by cell cytotoxicity assay. We had successfully construct the recombinant HSCC-1 adenovirus(Ad5CMV-HCCS-1). DNA extracted from Ad5CMV-HCCS-1 revealed HCCS-1 gene is incorporated. The transduction efficiencies were over than 50% of SCC-25 cells with a MOI of 2 and over 95% with a MOI of 50. Northern blot analysis showed that a single 0.6kb mRNA transcript was expressed in Ad5CMV-HCCS-1 transduced SCC-25 cells. There was no or very low transcription HCCS-1 mRNA in wild and Ad5CMV-LacZ transduced SCC-25 cells. Cells transduced with Ad5CMV-HCCS-1 showed significant growth inhibition. By day 6, Ad5CMV-HCCS-1 treated cell count was decreased to 30% of mock-infected cells, while that of Ad5CMV-LacZ treated cells was 90% of mock-infected cells (p<0.05). Finally, these result suggest that the Ad5CMV-HCCS-1 has potential as a gene therapy tool for oral cancer.

To compare the stimulation effect of the ratio in follicle stimulating hormone and luteinizing hormone in induction of multiple follicular growth, the serum $E_2$ level, the diameter of follicle, number of aspirated follicles and cleavage rate of in vitro fertilized preovulatory oocytes as well as the pregnancy rate were evaluated. Forty one patients with irreparable tubal disease were stimulated by hMG(n=24) or FSH/hMG(n=17) for the purpose of in vitro fertilization and embryo transfer. The following results were obtained. 1. Serum estradiol($E_2$) levels on the day of hCG administration were $921.0{\pm}353.3\;pg/ml$ in hMG group and $1272.9{\pm}1060.6\;pg/ml$ in FSH/hMG group. The serum $E_2$ value of hMG group was significantly lower than that of FSH/hMG group. 2. The diameter of leading follicle by ultrasonogram on the day of hCG administration were $16.2{\pm}2.0\;mm$ in hMG group and $16.2{\pm}2.6\;mm$ in FSH/hMG group. No significant difference of follicle diameter between two groups was demonstrated. 3. The number of follicles with diameter above 10 mm by sonogram on the day of hCG injection were $3.91{\pm}2.32$ in hMG group and $6.52{\pm}3.86$ in FSH/hMG group. There was significant difference of number of follicles between two groups, (p< 0.01). 4. The number of oocytes found per patient at aspiration were $2.59{\pm}1.00$ in hMG group and 3. $76{\pm}2.31$ in FSH/hMG group. There was significant difference of number of aspirated oocytes between two groups. (p< 0.05). 5. The detection rate of preovulatory oocyte at aspiration were 68.4%(39/57) in hMG group (n=22) and 77.6%(38/49) in FSH/hMG group (n=13). 6. The cleavage rate of preovulatory oocyte at 44 hours after insemination were 74.4%(29/39) in hMG group(n=22) and 81.6%(31/38) in FSH/hMG group (n=13). When only hMG was used, one pregnancy was established in 15 patients to whom 29 zygotes were transferred. And a full term normal female baby was delivered by elective cesarean section. In the FSH/hMG group, five pregnancies out of 9 transferred patients were confirmed by serum ${\beta}-hCG$. Two pregnancies were spontaneously aborted before the 6th week of pregnancy. One patient aborted her baby at the 18th week of pregnancy because of incompetent internal os of the cervix. Two patients delivered two full term babies by elective cesarean section. From the above findings, paralell with the increase in the ratio of exogenous follicle stimulating hormone to luteinizing hormone, an increase in oocyte recovery was observed as well as an improvements in pregnancy rate. It was concluded that FSH enrichment early in the follicular phase had a beneficial effect in the controlled ovarian hyperstimulation.
