Plasma renin activity (ORA) was determined by radioimmunoassay in 55 normal controls and 121 hypertensive patients in basal state and after double stimulation with furosemide administration and upright posture of 4 hrs. The results were obtained as follows, 1) Mean value of PRA of normal control was 2.2+/-1.41ng/ml/hr in basal state and 2.9+/-1.39ng/ml/hr after double stimulation, respectively. The latter was elevated significantly as compaired to the former. 2) PRA in males was significantly higher than in females, and PRA tend to be decreased as age become old. 3) Normal value of PRA after double stimulation was ranged from 1.0 to 5.0 ng/ml/hr. Of total 121 hypertensive patients(55 males and 66 females), PRA was low in 33 cases(27.3%), normal in 77 cases (63.6%), and high in 11 cases(9.1%). 4) Of 55 male hypertensive patients, PRA was low in 13 cases(23.6%), normal in 35 cases (63.7%), and high in 7 cases(12.7%). Of 66 female hypertensive patients,, PRA was low in 20 cases (30.3%), normal in 42 cases(63.6%), and high in 4 cases(6.1%). High renin group was observed more frequently in male hypertensive patients than in female hypertensive patients, while low renin group more frequently in famale than in male patients. 5) Low renin group was observed more frequently in older age group than in younger age group, while high renin group more frequently in younger age than in older age group.

OBJECTIVES: To understand the importance of the serum level of Ca-125 among pelvic mass, we performed a study. METHOD: From January to December 1998, we performed the study. Before hysterectomy, we performed a blood sampling to know the serum level of Ca-125, After hysterectomy, we weighed the uterus and measured the thickness of endometrium and other histologic characteristics. RESULTS: We performed my research to 80 peoples. The relation between uterine weight and the serum level of Ca-125 is little, if ever(R2=0.0007), and the relation between the thickness of endometrium and the serum level of Ca-125 is also little, if ever(R2=0.0353). The relation between leiomyoma, the cycle of endometrium and the serum level of Ca-125 were also little, but there was a close relationship between adenomyosis and the serum level of Ca-125. CONCLUSION: There was little relationship between uterine weight and the serum level of Ca-125.

The implatnation of malignant cells along the needle tract is an extremely rare complication after a percutaneous fine-needle aspiration biopsy(FNAB). However, it is very serious and may result in a change in the prognosis of lung cancer, especially in the curable early stage(T1-2,N0,M0). Recently, we experienced two cases of such complications. A 43 years old female underwent a fine needle aspiration biopsy and a right middle lobectomy with adjuvant chemotherapy due to an adenocarcinoma(T2N0M0). Two years later, a new tumor developed at the site of the needle aspiration biopsy. It had the same pathological findings as the previous lung cancer. Therefore, it was concluded to be an implantation metastasis, and she was treated successfully by a right pneumonectomy and a resection of the chest wall mall with adjuvant radiotherapy. In another case, a 62 years old man was diagnosed with squamous cell lung cancer by a fine needle aspiration biopsy and underwent a right upper lobectomy(T2N0M0) with adjuvant chemotherapy. eight months later, a protruding chest wall mass developed at the aspiration site. It showed the same pathological findings as the previous lung cancer. Consequently, a total excision of the mass with adjuvant radiotherapy was done. Two years after the second operation, although the right lung was intace a metachronous squamous cell lung cancer was found at the left lower lobe. The two patients were still alive 15 and 37 months after thenresection of the chest wall mass, respectively.

PURPOSE: Angiogenesis plays an important role in the growth, progression and metastasis of solid tumors. Vascular endothelial growth factor (VEGF) was thought to be one such angiogenic factor and was also thought to be a selective mitogen for endothelial cells. The purpose of this retrospective study was to evaluate for prognostic significance of VEGF in stomach cancer. MATERIALS AND METHODS: The sections of formalin-fixed, paraffin embedded from 55 stomach cancer were stained immunohistochemically for VEGF. The rate of VEGF expression and correlation between expression of VEGF and other prognostic factor of stomach cancer were studied. RESULTS: There were 20 cases (36.4%) of VEGF-positive and 35 cases (63.6%) of VEGF- negative. There were no significant difference between VEGF expression and the histologic type, differentiation, depth of invasion of histologic stage, lymph node involvement. The frequency of hepatic recurrence was higher in patients with VEGF-positive tumor than that af patient with negative tumor (p=0.007). The prognosis of the patients with VEGF positive tumor was worse than that of patients with VEGF negative tumor (p=0.0214). CONCLUSION: There was a closely significant between positive expression of VEGF and a high incidence of hepatic metastasis, low survival rate. The expression of VEGF could be considered to be one of useful prognostic factor in human gastric carcinoma

PURPOSE: Topoisomerase II-alpha is a key enzyme in DNA replication and a molecular target for many anti-cancer drugs. The C-erbB-2 oncogene (HER-2/neu) is the most frequently amplified oncogene in breast cancer. Because of the physical proximity of c-erbB-2 and topoisomerase II-alpha, co-amplification of the c-erbB-2 and topoisomerase II-alpha may occur. To investigate the clinical significance of the topoisomerase II-alpha and c-erbB-2, the correlation between topoisomerase II-alpha and c-erbB-2 was examined by immunohistochemical staining in 43 invasive ductal breast carcinomas and its relationship with other prognostic factors. METHODS: Topoisomerase II-alpha and c-erbB-2 expression was studied immunohistochemically using sections of formalin fixed, paraffin-embedded tumor specimens from 43 invasive ductal breast carcinomas. The correlation between topoisomerase II-alpha and c-erbB-2 expression, and its relationship with the clinicopathological factors such as the tumor size, lymph node metastasis, TNM stage, histological grade, nuclear grade, estrogen receptors and progesteron receptors was investigated. RESULTS: C-erbB-2 was expressed in 9 (20.9%) out of the 43 infiltrating ductal carcinoma cases. Among the prognostic factors, the tumor size, lymph node metastasis, tumor stage, nuclear grade, status of progesteron receptors and estrogen receptors did not significantly correlated with c-erbB-2 expression. The tumor size, lymph node metastasis, tumor stage, histological grade, and the absence of estrogen receptors displayed a significant relationship with the increase in the topoisomerase-alpha index. However, the topoisomerase II-alpha index did not correlate with the nuclear grade and the status of progesterone receptors. The topoisomerase II-alpha index was slightly higher in the c-erbB-2 positive expression cases compared to c-erbB-2 negative expression cases but this increase was not significant (P=0.503). CONCLUSION: These results suggest that topoisomerase II-alpha may play some role as a prognostic factor, but further investigation is needed.

PURPOSE: This study was aimed to determine the role of the VEGF and MVD expression in infiltrating ductal carcinoma of breast and to observe the correlation between the expression of these VEGF/MVD, and other prognostic factors. MATERIALS AND METHODS: Immunohistochemical staining of VEGF and MVD with monoclonal antibody in pathologic specimens of 35 patients of infiltrating ductal carcinoma of breast was carried out. Reiationship between the expression of the VEGF/MVD and prognostic factors were assessed. RESULTS: The VEGF/MVD expression was closely related to tumor size, lymph node metastasis, and clinical stage, but not related to histologic grade, nuclear grade, estrogen receptor, and progestrone receptor. And the VEGF expression was closely related to MVD. CONCLUSION: The VEGF expression and microvessel density in infiltrating ductal carcinoma of breast may play an important prognostic factors, closely related to the tumor size, lymph node metastasis, and stage.

Sarcopenia has been defined as the considerable loss of skeletal muscle mass and strength that results in frailty in the elderly. Because muscle tissue plays diverse important roles in human, sarcopenia presents many negative health-related consequences including impaired energy homeostasis, falls and cardiovascular disease, and subsequently higher mortality. It is becoming evident that sarcopenia has a negative impact on the healthy life of the elderly. The European Working Group on Sarcopenia, the International Working Group on Sarcopenia and the Asian Working Group on Sarcopenia have released position statement regarding sarcopenia, and more recently the Foundation for the National Institutes of Health Sarcopenia Project has provided a new guideline for assessment of sarcopenia. At this time, there have been several data delineating the status of sarcopenia in Korea. This review focuses on largescale cohorts that assessed sarcopenia and highlights the controversies surrounding the clinical definition and prevalence of sarcopenia in Korea.

PURPOSE: This study was to evaluate the effects of bacterial cellulose (BC) membranes as a barrier membrane on guided bone regeneration (GBR) in comparison with those of the resorbable collagen membranes. MATERIALS AND METHODS: BC membranes were fabricated using biomimetic technology. Surface properties were analyzed, Mechanical properties were measured, in vitro cell proliferation test were performed with NIH3T3 cells and in vivo study were performed with rat calvarial defect and histomorphometric analysis was done. The Mann-Whitney U test and the Wilcoxon signed rank test was used (alpha<.05). RESULTS: BC membrane showed significantly higher mechanical properties such as wet tensile strength than collagen membrane and represented a three-dimensional multilayered structure cross-linked by nano-fibers with 60 % porosity. In vitro study, cell adhesion and proliferation were observed on BC membrane. However, morphology of the cells was found to be less differentiated, and the cell proliferation rate was lower than those of the cells on collagen membrane. In vivo study, the grafted BC membrane did not induce inflammatory response, and maintained adequate space for bone regeneration. An amount of new bone formation in defect region loaded with BC membrane was significantly similar to that of collagen membrane application. CONCLUSION: BC membrane has potential to be used as a barrier membrane, and efficacy of the membrane on GBR is comparable to that of collagen membrane.
