PURPOSE: Vascular endothelial growth factor(VEGF) is recognized as a potent constituent of the vascularization and growth of solid tumors. We assessed the serum levels of VEGF and we evaluated its correlation to the clinicopathologic findings and clinical outcome of patients with renal cell carcinoma(RCC). MATERIALS AND METHODS: Serum samples were collected before surgery from patients with RCC. The levels of serum VEGF were assessed by using quantitative enzyme immunoassay. Comparison of the serum VEGF level with the tumor stage, grade, cell type and clinical outcome was performed, and the survival rate between the RCC patients above and below the mean VEGF level was evaluated. RESULTS: The mean follow-up was 5.1 years. The serum VEGF level was significantly higher in the patients with RCC(mean: 497pg/ml) than that in the controls(mean: 211pg/ml)(p<0.001). The serum VEGF level was correlated with the tumor size, the pathologic T stage and the clinical stage and histologic nuclear grade, but not with the histologic subtype. Patients with a lower VEGF level(<497pg/ml) showed longer survival(p=0.0207 on univariate analysis, p=0.04 on multivariate analysis). CONCLUSIONS: Our study indicated that the serum VEGF level was significantly correlated with the clinical or pathologic stage, the nuclear grade and adverse survival. These results suggest that the serum VEGF level could be a comparable prognostic factor to the tumor stage and grade.

Gliomatosis peritonei, the implantation of neuroglial tissue upon the peritoneal surface, is a rare event most often associated with solid or immature teratoma of the ovary in young girls. The majority of cases occur in association with teratomas containing immature element. However malignant transformation of the glial tissue has been reported. Here we experienced a case of mature glial implants presenting in an 27-year-old female, 10 years after initial diagnosis and removal of an ovarian immature teratoma, and report this case with brief review of literatures.

PURPOSE: Angiopoietin-1 (Ang-1) plays a crucial role in vascular and hematopoietic development, mainly through its cognate receptor, Tie-2. Increased levels of Ang-2 have been shown to be correlated with abnormal tumor angiogenesis in several malignancies. Hence, we estimated the increased expression of Ang-2 relative to Ang-1 in patients with colorectal cancer and correlated our finding with prognosis in order to investigate the relationships between the expressions of Ang-1/Ang-2/Tie-2 receptor and the clinical parameters or overall survival of such patients. METHODS: We retrospectively analyzed 114 tissue samples from patients with colorectal cancer by using immunohistochemistry (IHC) to examine Ang-1, Ang-2, and Tie-2 expressions and to investigate the relationship between those expressions and clinical parameters or overall survival of such patients. A Western blot analysis was used for Ang-2 expression. RESULTS: IHC staining showed a link between Ang-1 and Tie-2 (P = 0.018), as well as meaningful correlations between Ang-2 and Tie-2 receptor (P = 0.022) and between lymph-node metastasis and Ang-2 (P = 0.025). The stronger the IHC staining for Ang-2 expression was, the shorter the cumulative survival was (P = 0.016). CONCLUSION: A relationship was found to exist between Ang-2 and Tie-2 expressions. The Ang-2 was correlated with lymph-node metastasis, and high expression of Ang-2 was indicative of poor overall survival. These findings suggest that Ang-2 is a useful prognostic marker in the management of patients with colorectal cancer. In addition, we suggest that Ang/Tie-2 signaling plays an important role in the progression of colorectal cancer.

PURPOSE: Appendicitis is the most common abdominal surgical emergency. The diagnosis of appendicitis can be difficult, occasionally taxing the diagnostic skills of even the most experienced surgeon, and especially for diagnosing reproductive women. This study was designed to evaluate the various pathologies of the appendix and the other intraabdominal organs in patients who were preoperatively diagnosed with acute appendicitis, and we wanted to analyze the difference of the perioperative results between the reproductive women and the other patients. METHODS: The study was a retrospective analysis of 1,108 appendectomies that were performed from September 2003 to August 2006. The data were analyzed for the following parameters: the age-related and sex-related incidence of acute appendicitis, the rates of negative appendectomy, negative operation and appendicular perforation, and the incidence of other encountered pathologies. In addition, we present the clinical results of the reproductive women. RESULTS: The diagnostic accuracy for acute appendicitis was 87.2%. The negative appendectomy rate was 11.6% and it was significantly higher (20.8%) in the reproductive women than in the male patients of the same age (P=0.001). On the clinical analyses of the reproductive aged appendicitis group showed they a shorter pain duration and a higher WBC count, and more frequent epigastric discomfort, nausea, vomiting and RLQ tenderness (P< 0.05). CONCLUSION: We noted a high rate of negative appendectomy among reproductive female patients, so more care should be taken to diagnose these patients.

OBJECTIVE: The objectives of this study was to evaluate the correlation between myeloid differentiation protein 88 (MyD88) expression and paclitaxel effects on epithelial ovarian cancer cells and to evaluate whether paclitaxel had anti-apoptotic signals. METHODS: Epithelial ovarian cancer cells isolated from ascites and established cell lines were treated with increasing concentrations of paclitaxel (0.2 to 20 microM) for 24 and 48 hours and cell viability was determined using the CellTiter 96 AQueous One Solution Cell Proliferation Assay. Cytokine profiling was performed from culture supernatants using the Luminex 200 system. Nuclear factor-kappaB (NF-kappaB) activity was determined using a Luciferase reporter system. Levels of phospho-extracellular signal-regulated kinase (p-ERK) were measured by Western blot analysis. RESULTS: A strong signal for MyD88 expression was observed in R182, 01-19b and SKOV3 cells (MyD88-positive). A2780, R454 and 01-28 cells showed low levels of MyD88 (MyD88-negative). Paclitaxel effectively decreased cell viability in MyD88-negative A2780, R454, 01-28 cells after 24 and 48 hours (57%, 49%, 42% and 35%, 28%, 29%, respectively). MyD88-positive cells were resistant to paclitaxel. There was a significant increase in caspase-3/7 activity following paclitaxel treatment in MyD88-negative cells. No significant change in caspase-3/7 activity was detected in MyD88-positive cells. Paclitaxel induced NF-kappaB activation and enhanced the secretion of interleukin-6 (IL-6) and IL-8 in a dose dependent manner and induced ERK phosphorylation on MyD88-positive cells. CONCLUSION: Paclitaxel treatment for MyD88-positive ovarian cancer could have detrimental effects due to the paclitaxel-induced enhancement of NF-kappaB, ERK activities and pro-inflammatory cytokine production, which promote chemoresistance and tumor progression.

Changes of body temperature were observed in the esophagus and rectum by telethermometer during extracorporeal circulation in 40 cases of open heart for detection of significant differences in survivals and non-survivals. The following results were obtained; 1) Esophageal and rectal temperature(just prior to extracorporeal circulation) were 36.4+/-0.69 degrees C, 36.8+/-0.8 degrees C respectively in non-survivals and 36.0+/-0.73 degrees C, 36.4+/-0.8 degrees C in survivals after open heart surgery 2) Normal differences between rectal and esophageal temperature came to disappear after 30 minutes of extracorporeal circulation in two groups. 3) Esophageal temperatures were higher than rectal temperatures after extracorporeal circulation for open heart surgery in both groups. 4) Changes of temperature differences between rectum and esophagus have no correlation with mortality because of the variation in two areas in both groups.

This study introduces the Clinical practice guidelines (CPGs) appraisal system by the Korean Academy of Medical Sciences (KAMS). Quality management policies for CPGs vary among different countries, which have their own cultures and health care systems. However, supporting developers in guideline development and appraisals using standardized tools are common practices. KAMS, an organization representing the various medical societies of Korea, has been striving to establish a quality management system for CPGs, and has established a CPGs quality management system that reflects the characteristics of the Korean healthcare environment and the needs of its users. KAMS created a foundation for the development of CPGs, set up an independent appraisal organization, enacted regulations related to the appraisals, and trained appraisers. These efforts could enhance the ability of each individual medical society to develop CPGs, to increase the quality of the CPGs, and to ultimately improve the quality of the information available to decision-makers.

An experiment was planned to observe the histopathological alteration with administration of the Rheomacrodex and blood pressure changes in induced cerebral infarct after occlusion. Eighty well developed cats, weighing 2.3 to 3.5kg, were used in this experiment. The right MCA was exposed through temporal approach and the proximal part of the MCA was occluded with a silver clip. The animals were divided into 4 groups: The control group was comprised of 20 cats with occlusion of the right MCA alone, Rheomacrodex-treated group was comprised of 20 cats after occlusion of right MCA, induced hypotension and hypertension groups consisted in each 20 cats following occlusion of the MCA. The animals were sacrificed at intervals of 3 hours, 6 hours, 24 hours, 1 week and 2 weeks respectively after occlusion of the MCA. The animals were studied for clinical deficits and histopathological changes of the cerebral infarct according to the time courses. The results obtained were as follows: 1) In the control group, severe contralateral hemiplegia was developed in the early stage following the MCA occlusion, however the neurological deficits were progressively improved to the state of abnormal walking in 24 hours to 2 weeks. The hemorrhagic infarct was involving the basal ganglia, internal capsule and extending to the cortex with mild brain edema in the early stage and the area of the infarct was gradually enlarged from 6 hours to 24 hours following the MCA occlusion. Although the brain edema of surrounding area of the lesion was remained unchanged, the size and distribution of the infarct were decreased in one week to 2 weeks. Extensive ischemic neuronal damage was observed in the control group. 2) In the Rheomacrodex-treated group, mild to moderate neurological deficit was developed in the early stage after MCA occlusion and the deficit was less severe than control group. The clinical deficit was improving in the time course and one case had shown completely normal activity in 2 weeks. The distribution of the infarct was well defined and it was smaller than control group. The infarct mainly involved the basal ganglia and internal capsule. The area of the infarct was gradually enlarged from 6 hours to one week after MCA occlusion, then the extent of the infarct was decreased in 2 weeks. The ischemic neuronal change in this group was less severe than control group. 3) In the induced hypotension group, the early neurological deficit was worse than that of the control group and severe hemiplegia was developed in one week. There was minimal improvement of the neurological deficit in 2 weeks. The area of the infarct was ill-defined and hemorrhagic extending a large portion of the brain with severe brain edema. The infart was involving the basal ganglia, internal capsule, claustrum and the cortex from 3 hours to 24 hours after the occlusion and the area of the infarct was not changed during the observation. Severe ischemic nerve cell change or resolution of the cells was oserved in this group. 4) In the induced hypertension group, the neurological deficit was mild and it was better than that of the control group. The distribution of the infarct was well localized and minimum in extent. The extent of the infarct was not changed during the observation. There was no observable gross brain edema and the ischemic nerve cell changes were not severe.

We reviewed 49 cases of moderate or severe pericardial effusion on which we performed pericardiocentesis and percutaneous pericardial biopsy from Jan. 1987 to Sep. 1989. Of these, 11 cases were performed percutaneous pericardial biopsy in order to diagnose confirmative. We studied clinical manifestation including physical examination, ECG, and radiology, etiology and complication of pericardiocentesis and percutaneous pericardial biopsy. The results are as belows : 1) The physical examination of pericardial effusion were neck vein engorgement(73.5%), priction rub(25.5%), and pulsus paradoxus(4%). The ECG findings were low voltage(77.6%) and electrical alternans(16.5%), and most common x-ray finding was cardiomegaly (81.6%). 2) Underlying diseases were as follows : neoplastic disease(40.8%), tuberculosis(18.4%) systemic lupus erythematosus(10.2%), hemopericardium(8.2%), chronic renal failure(6.1%), congestive heart failure(4.1%), idiopathic pericarditis(4.1%), GVHD(2.0%), pyopericardium(2.0%), rheumatic carditis(2.0%), and postpericardiotomy syndrome(2.0%), in order. 3) Special etiologic diagnosis of neoplasm were lung cancer(50%), adenocarcinoma of unknown origin(20%), Malignant lymphoma(15%), stomach cancer(5%), hepatoma(5%), and malignant thymoma(5%), in order. From the percutaneous pericardial biopsy, the authors confirmed 36% by finding two cases of malignancy and two cases of tuberculosis. On the other hand, only one case was confirmed in cytology. These result in a rather low rate of diagnostic confirm. There were 8 cases of complication : hypotension(8.2%), premature ventricular contraction(6.1%) and ventricular tachycardia (2.0%) without death cases. In percutaneous pericardial biopsy, only two cases of hypotension were found with no death case. The result obtained from the above 11 cases of percutanous pericardial biopsy is not enough to make conclusive statement concerning rate of diagnostic confirmation and complication. We expect better results by examining more cases in the future.

OBJECTIVE: The effect of basal day 3 luteinizing hormone (LH) and pituitary desensitized day 3 LH level on ovarian response to controlled ovarian hyperstimulation were investigated. METHODS: From January 1999 to December 2001, 445 cycles for in vitro fertilization and embryo transfer (IVF-ET) were allocated to this study. Controlled ovarian hyperstimulation (COH) was performed using long protocol of gonadotropin-releasing hormone agonist (GnRHa). All patients included in this study had blood samples drawn on cycle day 3 prior to COH and cycle day 3 after pituitary desensitization with GnRHa for measurement of FSH and LH. Infertile women were younger than 43 years old, and had normal menstrual cycle, normal day 3 FSH and LH level (<10 mIU/ml), infertility factor caused by tubal factor, mild endometriosis, unexplained infertility or mild male subfertility. The result of COH and IVF-ET were compared between low LH group and high LH group according to the level of basal LH (3 mIU/ml) and down-regulated LH (1 mIU/ml). RESULTS: The low LH groups were significantly higher FSH:LH ratio, higher dose of exogenous gonadotropin for pituitary desensitization, longer duration of gonadotropin administration. The peak estradiol, number of oocytes retrieved, number of MII oocyte, mean cumulative embryo score (MCES) were significantly lower in the low LH group than the high LH group. There were not significantly differentiation in the duration of pituitary desensitization, fertilization rate and the number of transferred embryos. The clinical pregnancy rate per cycle was not correlated with the value of basal LH concentration, but correlated with the value of down-regulated LH concentration. CONCLUSION: The lower LH activity (basal LH <3 mIU/ml, down-regulated LH <1 mIU/ml) is significantly associated with reduced ovarian response in controlled ovarian hyperstimulation after desensitization with GnRHa. These results suggest that down-regulated LH level 1 mIU/ml may be a useful predictor of the clinical pregnancy rate per cycle after controlled ovarian hyperstimulation.
