BACKGROUND: To study the prognosis of patients with lung cancer, many investigators have reported the methods to detect cell proliferation in tissues including PCNA, thymidine autoradiography, flow cytometry and Ki-67. PCNA, also known as cyclin, is a cell related nuclear protein with 36KD intranuclear polypeptide that is maximally elevated in S phase of proliferating cells. In this study, PCNA was identified by paraffin-embedding tissue using immunohistochemistry which has an advantage of simplicity and maintenance of tissue architecture. The variation of PCNA expression is known to be related with proliferating fraction, histologic type, anatomic(TNM) stage, degree of cell differentiation, S-phase fraction and survival rate. We analyzed the correlation between PCNA expression and S-phase fraction, survival. METHODS: To investigate expression of PCNA in primary lung cancer, we used immunohistochemical stain to paraffin-embedded sections of 57 resected primary non-small cell lung cancer specimen and the results were analyzed according to the cell type, cell differentiation, TNM stage, S-phase fraction and survival. RESULTS: PCNA expression was dMded into five group according to degree of staging(-, +, ++, +++,++++). Squamous cell type showed high positivity than in adenocarcinoma. Nonsignificant difference related to TNM stage was noticed. Nonsignificant difference related to degree of cell differentiation was noticed. S-phase fraction was increased wit advance of PCNA positivity, but t could not reach the statistic significance. The 2 year survival rate and median survival time were -50% 13 months, +75% 41.3 months, ++73% 33.6 months, +++67% 29.0 months, ++++25% 9 months with statistic significance (P<0.05, Kaplan-Meier, generalized Wilcox). CONCLUSION: From this study. PCNA expression was high positive n squamous cell cancer. And, there was no relationship between PCNA positivity and TNM stage, cellular differentiation or S-phase fraction. But, the patients with high positive PCNA staining showed poor survival rate than the patients with lower positive PCNA. It was concluded that PCNA immunostaining is a simple and useful method for survival prediction in paraffin embedded tissue of non-small cell lung cancer.

PURPOSE: The purpose of this study is to evaluate the signal intensity and size of anterior pituitary gland in postpartum women, and to compare with those of control group. MATERIALS AND METHODS: In 34 postpartum women(18-43 years, mean:27 years) and another 35 control nonpregnant women(20-29 years, mean :24 years), midsagittal Tl-weighted MR images were obtained. The signal intensity and height of the anterior pituitary gland were compared between the post-partum and normal control groups. RESULTS: In postpartum women, the signal intensity of the anterior pituitary gland relative to the pons was higher than that of the control gorup. Pituitary gland height of postpartum women was higher(5-11. 8mm, mean:8.18 +/- 1.8mm) than that of control group(2-9mm, mean :6.2 +/- 1.7mm). CONCLUSION: It is concluded that the hyperintensity of the anterior pituitary gland on Tl-weighted image is a normal finding in postpartum women, which is useful in differentiation from pituitary abnormality.

In order to evaluate the value of vertebral angiography in assessment of hemifacial spasm, we reviewed retrospectively the vertebral angiography of 28 patients(30 cases) with surgically proved hemifacial spasm but normal CT scans of posterior fossa. There were 9 males and 19 females. Angiography revealed vascular focus of hemifacial spasm located at anterior inferior cerebellar artery, posterior inferior cerebellar artery, and vertebral artery in 19, 9, and 2 cases respectively. Right side was involved in 20 cases. All involved vessels were elongated, tortuous, and dilated. In conclusion, vertebral angiography was valuable in evaluating hemifacial spasm of vascular origin in the posterior fossa.

OBJECTIVE: The purpose of this study was to investigate clinical charactoristics of adenocarcinoma of the uterine cervix. STUDY METHODS: This study is a retrospective analysis of 103 patients with adenocarcinoma of cervix treated at the Kosin Medical center forom 1984 to 1993. RESULTS: The distribution by stage of disease included FIGO stage I, 51(49.6%); stage II, 32(31%); Stage III, 17(16.5%);Stage IV, 3(2.9%). The 2-year survival results for patients with stage I was 93.5%; stage II was 72.4%;stage III was 46.2% and stage IV was none survived. And 4 year survival results,'83.3/o, 591% and 33.3/o in stage I, II and III, reqxetively. The 4-year survivel rate varied significantly according to tumor size and lymph nade metastasis status-below 2cm 84.2%, 2cm~4cm 75%, above 4cm 0%: (stage I);negative node 91.3%, positive node 40% (stage I). The results of resurrent rate according to clinical stage was 11.8%, 25.8%, 84.6% and 100 % in stage I, ll, III and lV, respectively. CONCLUSION: Treatment strategies should be based on the stage of disease, tumor size, lymph node metastasis status and recurrent.

Twenty-eight cases of fracture of the femur and tibia on the same leg were treated in Pusan Maryknoll Hospital during the period from April 1981 to Jun 1988. We studied all of these patients, divided by five groups according to the method of treatment, with analysis of treatment and end results. The following results were obtained. 1. The incidence of trauma was high in the young man, and most frequent in the third decade (42.9%). 2. The main cause of injuries was traffic accident; 22 patients (78.6%). 3. The common fracture site was middle one-third in femur and tibia respectively. 4. The most common associsted injury was head trauma (9 case). 5. The average healing time of fracture was 20.7 weeks in femur and 22.7 weeks in tibia of group 3, 4, 5. 6. The best results were obtained in cases both fractures stabilized surgically.

Ilizarov technique has been successfully applied to limb lengthening for several decade, one of its main drawback is, however, long application of external fixator over 6 months. To lessen this time, simultaneous intramedullary fixation which convert later to static fixation by insertion of interlocking screws has been proposed. The indication for surgical limb lengthening includes familial short stature below the 3rd percentile. We compared the results of thirteen tibial lengthening with Ilizarov method to that of eleven hybrid methods. The hybrid system is composed of an unreamed AO intramedullary nail (IM) and ring fixator. Once the lengthening is completed, distal interlocking screws were inserted. In the group who were treated by hybrid system, the mean lengthening of tibia was 7.1cm (range, 6.3-9.5), the mean of external fixation period 7 months (range, 5-9), the mean healing index 1.2 month/cm (range, 1.1-1.4). On the other hand, the mean lengthening of tibia was 7.5cm (range, 5-10.3), the mean of external fixation period 9.8 months (range, 6-15), the mean healing index 1.4 month/cm (range, 1.1-1.8) in the group treated by Ilizarov method. Mean follow-up period was 23 months (range 14-47). There was no rotational or angular deformities and no loss of lengthening in the hybrid group. However we experienced three cases of angular deformity at the distraction site during lengthening in Ilizarov group. There was no deep infection in both groups. In the hybrid group we found several advantages such as no deformity, no loss of lengthening, and less scar by early removal of fixator, but some disadvantages such as need of subsequent procedures and limitation in intramedullary nailing.

PURPOSE: Our purpose in this study is to evaluate the effectiveness of bronchial and nonbronchial systemic arteries for the control of hemoptysis. MATERIALS AND METHODS: Seventy patients with massive or recurrent hemoptysis underwent percutaneous transcatheter embolotherapy between 1991 and 1993. Retrospectively we reviewed 77 cases of bronchial artery embotization and 32 cases of nonbronchial systemic artery embolization in the 70 patients. RESULTS: Immdiate control of hemoptysis was achieved in 33 of 39 patients with massive hemoptysis(84.6%) and 20 of 24 patients with recurrent hemopt ysis(83.3%). In 32 cases, nonbronchial systemic arteries contributed significantly to areas of pathologic pulmonary tissue and frequently were the major arterial supply. CONCLUSION: Bronchial artery embolization is an effective and life saving procedure in non-surgical candidates. Recognition and occlusion of nonbronchial systemic arteries that feed to hypervascular pulmonary lesions is essential for successful percutaneous embolotherapy of hemoptysis.
