In general, hangman's fracture, odontoid Type III fractures, and most miscellaneous axis fractures are effectively managed with nonoperative methods (typically, the halo vest with its rigid external immobilization). Halo apparatus is a reliable instrument for the management of cervical spine injury, including that of odontoid fractures and other C1-2 injuries. Surgical fusion is the usual alternative to the halo device. Posterior wiring with or without fusion using autogenous iliac bone graft is probably the most common surgical treatment of cervical spine fracture and dislocation. The purpose of this study was to compare with stability of each others and to estimate the atlanto-dental interval and space for available in patients who were received conservative treatment and operative treatment due to upper cervical spine fracture and/or dislocation. 25 patients who were recieved conservative and operative management due to fracture and/or dislocation of the upper cervical spine (Cl and C2) during 1990. Jan. to 1997. May. were defined as a patient group. 12 patients were received conservative treatment. 13 patients were received operative treatment. In patient group who were received conservative treatment, the average of ADI and SAC was within normal range. In patient group who were received operative treatment, the average of ADI and SAC was within normal range. The patient group with the ADI and SAC of normal range were stable with good bone union at the last follow-up examination. Also the patient group was received fusion as their initial treatment for injuries incurred 1 month to 8 month prior to hospitalization were stable with good bone union.

In order to assess the role of postoperative radiotherapy and prognostic factors, 50 patients who were treated with radiotherapy after surgery for clinical early-stage carcinoma of the cervix were reviewed. All patients received external pelvic radiotherapy alone(dose range 4,500 cGy-6,480 cGy, median 5,040 cGy). The 5 year overall survival, disease free survival and locoregional control rates were 93%, 87% and 90%, respectively. Clinical stage was found to he a statistically significant prognostic factor on univariate analysis (p=0.003) but clinical stage and pathological pararnetrial invasion on multivariate analysis (p=0.016, 0.041). Grade Ⅰ and Ⅱ complication rate was 4% in all patients. In conclusion, postoperative radiotherapy should be used in patients treated with radical hysterectomy with unfavorable pathological findings and clinical stage IIB patients is recommended to be treated by radical radiotherapy rather than surgery due to their poor prognosis shown in this study.

The phagocytic activity of murine peritoneal macrophage was determined by lucigenin chemiluminescence and engulfment of fluorescein-conjugated E. coli particles. The activity-guided fractionation upon the methylenechloride fraction of Aurantii immaturi pericarpium led to the isolation of a flavonoid, isosinensetin, as a suppressive component of phagocytosis, lsosinensetin suppressed the lucigenin chemiluminescence and the engulfment of fluorescein-conjugated E. coli particles and enhanced the production of nitric oxide in murine peritoneal macrophage.

To evaluate the effect of radiation therapy and prognostic factors in metastatic brain tumor, we analyzed the 29 patients diagnosed as brain metastases and treated with radiation therapy, retrospectively. We evaluated the symptom palliation effect and mean survival time of patients treated with radiation therapy by means of prognostic factors such as initial performance status, primary site, extracranial metastasis, radiation dose etc. Conclusively, we confirmed the good symptomatic response rate but poor survival time of these patients. Also, this study revealed that prognostic factors of metastatic brain tumor treated with radiation therapy were initial preformance status, age and radiation dose but sex, use of steroid, primary site and extracranial metastasis were not. To increase the survival time of the patients with brain metastases, further study for adequate radiation dose/fractionation schedule, combination with chemotherapy and surgical resection, and stereotactic radiotherapy will be needed.

척추관 협착증에 대한 연구 : 요추관 협착증 환자에서 협착 부위에 따른 수술적 치료의 결과 Results of the Operative Treatments by the Level of Lumbar Spinal Stenosis

Spinal stenosis is any type of narrowing of the main spinal canal, nerve canal or foramina from structural abnormality of bony components. Posterior decompression only provide relief of pain and restoration of neurologic function, and simultaneous posterolateral fusion is needed for prevention of spinal instability after wide posterior decompression. The degree of decompression (focal or wide), instrumentation and bone graft is dependent to the level of stenosis and instability. The purpose of this study is to compare the operative results clinically and radiologically by the level of spinal stenosis. We reviewed 73 patients of lumbar spinal stenosis who had undergone operations with posterior decompression or posterolateral fusion with spinal instrumentation at our hospital, From January 1987 to October 1997. We classified the level of stenosis into one level, two level and multi-level(above three level) stenosis, and on the last follow up, radiological bony union, clinical results, and complications were compared. The following results were obtained. I. The one level was 42 cases(57.6%), two level 24 cases(32.9%), and multi-level stenosis 7 cases(9.6%) and the most common stenotic level was at LA-5, 31 cases(42.5%). 2. Posterior decompression only were carried out on 20 patients(27.4%), and simultaneous posterolateral fusion with instrumentation were 53 patients(72.6%), CD 4 cases, CCD 11 cases, PWB 2 cases, and Diapason 36 cases. 3. The radiologic union rate was 41 cases(97.6%) in one level, 22 cases(87.5%) in two level, 6cases(85.7%) in multi-level spinal stenosis. 4. The excellent or good clinical results(by the Kikaldy-Willis criteria) were 40 cases (95.2%) in one level, 22 cases(91.8%) in two level, 6 cases(85.7%) in multi-level spinal stenosis. 5. The postoperative complications such as infection, metal failure, neurologic deficit or death were 6 cases(14.3%) in one level, 4 cases(21%) in two level, 3 cases(44.3%) in multi-level stenosis.

The purpose of this research was to investigate effects of Sa-Kunja-Tang(SKT) on immune cells of L1210 cell-transplanted mice. The apoptosis and T lymphocytes subopoulation were tested using a flow cytometry, and the proliferation was tested using a MTT assay. Nitric oxide production from mouse peritoneal macrophage was tested using a Griess reagents, and the phagocytic activity of mouse peritoneal macrophage was tested using a lucigenin chemiluminescence. SKT suppressed apoptosis of T-lymphocytes induced by L1210 transplantation. SKT decreased nitric oxide production from mice peritoneal macrophages increased by L1210 transplantation, and the phagocytic activity decreased by L1210 transplantation. These results suggest that SKT suppresses T lymphocyte apoptosis and macrophage activity in L1210 transplanted mice.

The purpose of this research was to investigate effects of Sa-Kunja-Tang(SKT) on immune cells of antitumor drugs administered mice. The apoptosis and T lymphocytes subpopulation were tested using a flow cytometry, and the proliferation was tested using a MTT assay. The administration of etoposide. vincristine or doxorubicin increased the apoptosis of T-lymphocytes, but the action of doxorubicin was decreased by the administration of SKT. The administration of etoposide or vincristine decreased helper T and cytotoxic T cells population of T lymphocytes, but the action of vincristine was recovered by the administration of SCT. The administration of etoposide, vincristine or doxorubicin decreased the proliferation of T-lymphocytes, but the action of doxorubicin was increased by the administration of SKT. These results suggest that SKT has a regulative function of T-lymphocytes in anti-tumor drugs administered mice.

우리 나라 해사중재의 현황과 개선 방안

성재모,김성준 한국해운물류학회 2003 해운물류:이론과실천 Vol.- No.5

해운, 무역, 보험과 관련한 분쟁은 법원보다는 중재에 회부되는 경우가 일반적이다. 그러나 국내 해운선사들이 해운 분쟁을 대한상사중재원에 회부하는 건수는 갈수록 줄어들고 있고, 대부분은 런던해사 중재에 회부되고 있다. 이번 연구에서는 해운선사의 해사중재현황을 5개 선사를 중심으로 조사하였다. 조사결과 용선분쟁의 90% 이상이 런던해사중재에 회부되고 있고, 대한상사중재원에 회부되는 중재는 2.2%에 불과했다. 이는 해사 분쟁의 당사자가 국내 선사와 제3국 기업이 주류를 차지하고 있는 것이 가장 큰 원인인 것으로 파악된다. 그밖에 해운과 관련한 영국의 판례가 용선계약서 해석의 원칙이 되고 있는 것이 해운업계의 오랜 관행으로 자리잡고 있는 것도 주요한 원인으로 작용하였다. 해운과 관련한 계약은 대부분 국제간에 이루어지기 때문에 해상법이 발달한 영국법에 기초한 런던중재조항이 분쟁 당사자들에게는 공평하게 느껴질 수 있다. 하지만, 국내 선사들간의 해사 분쟁 중 다수가 런던중재를 이용하고 있는 것으로 나타나고 있다. 따라서 현재 대한상사중재원에서 취급하고 해사중재제도가 갖고 있는 문제점을 파악하고, 그 개선방안을 모색해 보았다. It is quite general that a dispute concerned with shipping, trading and insurance is referred to the arbitration panel instead of court. But, the number of case referred to the Korea Commercial Arbitration Board in respect of shipping become fallen every year. Instead, most disputes are referred to the London Maritime Arbitrators Association. The focus of this research is to investigate the current situation of arbitration cases in Korean shipping companies in more details. In the result of the research, it shows that more than 90% of charterparty dispute is referred to the London Maritime Arbitrators Association and only 2.2% is referred to the Korea Commercial Arbitration Board. That is why many leading cases under English law has become a principle of interpretation of the shipping contracts and become a custom in the shipping area. The contributory cause of the above situation is that the Korea Commercial Arbitration Board has a systematic problem. As many contracts concerned with shipping is internationally made, many people in the shipping area might feel that the London Arbitration Clause based on English law would be fair and reasonable. Nevertheless, we should recognize the Korea Commercial Arbitration Board's systematic problem and grope for a method of improving the systematic problem.
